   1CONFIGURATION FILE
   2------------------
   3
   4The Git configuration file contains a number of variables that affect
   5the Git commands' behavior. The `.git/config` file in each repository
   6is used to store the configuration for that repository, and
   7`$HOME/.gitconfig` is used to store a per-user configuration as
   8fallback values for the `.git/config` file. The file `/etc/gitconfig`
   9can be used to store a system-wide default configuration.
  10
  11The configuration variables are used by both the Git plumbing
  12and the porcelains. The variables are divided into sections, wherein
  13the fully qualified variable name of the variable itself is the last
  14dot-separated segment and the section name is everything before the last
  15dot. The variable names are case-insensitive, allow only alphanumeric
  16characters and `-`, and must start with an alphabetic character.  Some
  17variables may appear multiple times; we say then that the variable is
  18multivalued.
  19
  20Syntax
  21~~~~~~
  22
  23The syntax is fairly flexible and permissive; whitespaces are mostly
  24ignored.  The '#' and ';' characters begin comments to the end of line,
  25blank lines are ignored.
  26
  27The file consists of sections and variables.  A section begins with
  28the name of the section in square brackets and continues until the next
  29section begins.  Section names are case-insensitive.  Only alphanumeric
  30characters, `-` and `.` are allowed in section names.  Each variable
  31must belong to some section, which means that there must be a section
  32header before the first setting of a variable.
  33
  34Sections can be further divided into subsections.  To begin a subsection
  35put its name in double quotes, separated by space from the section name,
  36in the section header, like in the example below:
  37
  38--------
  39        [section "subsection"]
  40
  41--------
  42
  43Subsection names are case sensitive and can contain any characters except
  44newline and the null byte. Doublequote `"` and backslash can be included
  45by escaping them as `\"` and `\\`, respectively. Backslashes preceding
  46other characters are dropped when reading; for example, `\t` is read as
  47`t` and `\0` is read as `0` Section headers cannot span multiple lines.
  48Variables may belong directly to a section or to a given subsection. You
  49can have `[section]` if you have `[section "subsection"]`, but you don't
  50need to.
  51
  52There is also a deprecated `[section.subsection]` syntax. With this
  53syntax, the subsection name is converted to lower-case and is also
  54compared case sensitively. These subsection names follow the same
  55restrictions as section names.
  56
  57All the other lines (and the remainder of the line after the section
  58header) are recognized as setting variables, in the form
  59'name = value' (or just 'name', which is a short-hand to say that
  60the variable is the boolean "true").
  61The variable names are case-insensitive, allow only alphanumeric characters
  62and `-`, and must start with an alphabetic character.
  63
  64A line that defines a value can be continued to the next line by
  65ending it with a `\`; the backquote and the end-of-line are
  66stripped.  Leading whitespaces after 'name =', the remainder of the
  67line after the first comment character '#' or ';', and trailing
  68whitespaces of the line are discarded unless they are enclosed in
  69double quotes.  Internal whitespaces within the value are retained
  70verbatim.
  71
  72Inside double quotes, double quote `"` and backslash `\` characters
  73must be escaped: use `\"` for `"` and `\\` for `\`.
  74
  75The following escape sequences (beside `\"` and `\\`) are recognized:
  76`\n` for newline character (NL), `\t` for horizontal tabulation (HT, TAB)
  77and `\b` for backspace (BS).  Other char escape sequences (including octal
  78escape sequences) are invalid.
  79
  80
  81Includes
  82~~~~~~~~
  83
  84The `include` and `includeIf` sections allow you to include config
  85directives from another source. These sections behave identically to
  86each other with the exception that `includeIf` sections may be ignored
  87if their condition does not evaluate to true; see "Conditional includes"
  88below.
  89
  90You can include a config file from another by setting the special
  91`include.path` (or `includeIf.*.path`) variable to the name of the file
  92to be included. The variable takes a pathname as its value, and is
  93subject to tilde expansion. These variables can be given multiple times.
  94
  95The contents of the included file are inserted immediately, as if they
  96had been found at the location of the include directive. If the value of the
  97variable is a relative path, the path is considered to
  98be relative to the configuration file in which the include directive
  99was found.  See below for examples.
 100
 101Conditional includes
 102~~~~~~~~~~~~~~~~~~~~
 103
 104You can include a config file from another conditionally by setting a
 105`includeIf.<condition>.path` variable to the name of the file to be
 106included.
 107
 108The condition starts with a keyword followed by a colon and some data
 109whose format and meaning depends on the keyword. Supported keywords
 110are:
 111
 112`gitdir`::
 113
 114        The data that follows the keyword `gitdir:` is used as a glob
 115        pattern. If the location of the .git directory matches the
 116        pattern, the include condition is met.
 117+
 118The .git location may be auto-discovered, or come from `$GIT_DIR`
 119environment variable. If the repository is auto discovered via a .git
 120file (e.g. from submodules, or a linked worktree), the .git location
 121would be the final location where the .git directory is, not where the
 122.git file is.
 123+
 124The pattern can contain standard globbing wildcards and two additional
 125ones, `**/` and `/**`, that can match multiple path components. Please
 126refer to linkgit:gitignore[5] for details. For convenience:
 127
 128 * If the pattern starts with `~/`, `~` will be substituted with the
 129   content of the environment variable `HOME`.
 130
 131 * If the pattern starts with `./`, it is replaced with the directory
 132   containing the current config file.
 133
 134 * If the pattern does not start with either `~/`, `./` or `/`, `**/`
 135   will be automatically prepended. For example, the pattern `foo/bar`
 136   becomes `**/foo/bar` and would match `/any/path/to/foo/bar`.
 137
 138 * If the pattern ends with `/`, `**` will be automatically added. For
 139   example, the pattern `foo/` becomes `foo/**`. In other words, it
 140   matches "foo" and everything inside, recursively.
 141
 142`gitdir/i`::
 143        This is the same as `gitdir` except that matching is done
 144        case-insensitively (e.g. on case-insensitive file sytems)
 145
 146A few more notes on matching via `gitdir` and `gitdir/i`:
 147
 148 * Symlinks in `$GIT_DIR` are not resolved before matching.
 149
 150 * Both the symlink & realpath versions of paths will be matched
 151   outside of `$GIT_DIR`. E.g. if ~/git is a symlink to
 152   /mnt/storage/git, both `gitdir:~/git` and `gitdir:/mnt/storage/git`
 153   will match.
 154+
 155This was not the case in the initial release of this feature in
 156v2.13.0, which only matched the realpath version. Configuration that
 157wants to be compatible with the initial release of this feature needs
 158to either specify only the realpath version, or both versions.
 159
 160 * Note that "../" is not special and will match literally, which is
 161   unlikely what you want.

 207
 208Values
 209~~~~~~
 210
 211Values of many variables are treated as a simple string, but there
 212are variables that take values of specific types and there are rules
 213as to how to spell them.
 214
 215boolean::
 216
 217       When a variable is said to take a boolean value, many
 218       synonyms are accepted for 'true' and 'false'; these are all
 219       case-insensitive.
 220
 221        true;; Boolean true literals are `yes`, `on`, `true`,
 222                and `1`.  Also, a variable defined without `= <value>`
 223                is taken as true.
 224
 225        false;; Boolean false literals are `no`, `off`, `false`,
 226                `0` and the empty string.
 227+
 228When converting value to the canonical form using `--bool` type
 229specifier, 'git config' will ensure that the output is "true" or
 230"false" (spelled in lowercase).
 231
 232integer::
 233       The value for many variables that specify various sizes can
 234       be suffixed with `k`, `M`,... to mean "scale the number by
 235       1024", "by 1024x1024", etc.
 236
 237color::
 238       The value for a variable that takes a color is a list of
 239       colors (at most two, one for foreground and one for background)
 240       and attributes (as many as you want), separated by spaces.
 241+
 242The basic colors accepted are `normal`, `black`, `red`, `green`, `yellow`,
 243`blue`, `magenta`, `cyan` and `white`.  The first color given is the
 244foreground; the second is the background.
 245+
 246Colors may also be given as numbers between 0 and 255; these use ANSI
 247256-color mode (but note that not all terminals may support this).  If
 248your terminal supports it, you may also specify 24-bit RGB values as
 249hex, like `#ff0ab3`.
 250+
 251The accepted attributes are `bold`, `dim`, `ul`, `blink`, `reverse`,
 252`italic`, and `strike` (for crossed-out or "strikethrough" letters).
 253The position of any attributes with respect to the colors
 254(before, after, or in between), doesn't matter. Specific attributes may
 255be turned off by prefixing them with `no` or `no-` (e.g., `noreverse`,
 256`no-ul`, etc).
 257+
 258An empty color string produces no color effect at all. This can be used
 259to avoid coloring specific elements without disabling color entirely.
 260+
 261For git's pre-defined color slots, the attributes are meant to be reset
 262at the beginning of each item in the colored output. So setting
 263`color.decorate.branch` to `black` will paint that branch name in a
 264plain `black`, even if the previous thing on the same output line (e.g.
 265opening parenthesis before the list of branch names in `log --decorate`
 266output) is set to be painted with `bold` or some other attribute.
 267However, custom log formats may do more complicated and layered
 268coloring, and the negated forms may be useful there.
 269
 270pathname::
 271        A variable that takes a pathname value can be given a
 272        string that begins with "`~/`" or "`~user/`", and the usual
 273        tilde expansion happens to such a string: `~/`
 274        is expanded to the value of `$HOME`, and `~user/` to the
 275        specified user's home directory.
 276
 277
 278Variables
 279~~~~~~~~~
 280
 281Note that this list is non-comprehensive and not necessarily complete.
 282For command-specific variables, you will find a more detailed description
 283in the appropriate manual page.
 284
 285Other git-related tools may and do use their own variables.  When
 286inventing new variables for use in your own tool, make sure their
 287names do not conflict with those that are used by Git itself and
 288other popular tools, and describe them in your documentation.
 289
 290
 291advice.*::
 292        These variables control various optional help messages designed to
 293        aid new users. All 'advice.*' variables default to 'true', and you
 294        can tell Git that you do not need help by setting these to 'false':
 295+
 296--
 297        pushUpdateRejected::
 298                Set this variable to 'false' if you want to disable
 299                'pushNonFFCurrent',
 300                'pushNonFFMatching', 'pushAlreadyExists',
 301                'pushFetchFirst', and 'pushNeedsForce'
 302                simultaneously.
 303        pushNonFFCurrent::
 304                Advice shown when linkgit:git-push[1] fails due to a
 305                non-fast-forward update to the current branch.
 306        pushNonFFMatching::
 307                Advice shown when you ran linkgit:git-push[1] and pushed
 308                'matching refs' explicitly (i.e. you used ':', or
 309                specified a refspec that isn't your current branch) and
 310                it resulted in a non-fast-forward error.
 311        pushAlreadyExists::
 312                Shown when linkgit:git-push[1] rejects an update that
 313                does not qualify for fast-forwarding (e.g., a tag.)
 314        pushFetchFirst::
 315                Shown when linkgit:git-push[1] rejects an update that
 316                tries to overwrite a remote ref that points at an
 317                object we do not have.
 318        pushNeedsForce::
 319                Shown when linkgit:git-push[1] rejects an update that
 320                tries to overwrite a remote ref that points at an
 321                object that is not a commit-ish, or make the remote
 322                ref point at an object that is not a commit-ish.
 323        statusHints::
 324                Show directions on how to proceed from the current
 325                state in the output of linkgit:git-status[1], in
 326                the template shown when writing commit messages in
 327                linkgit:git-commit[1], and in the help message shown
 328                by linkgit:git-checkout[1] when switching branch.
 329        statusUoption::
 330                Advise to consider using the `-u` option to linkgit:git-status[1]
 331                when the command takes more than 2 seconds to enumerate untracked
 332                files.
 333        commitBeforeMerge::
 334                Advice shown when linkgit:git-merge[1] refuses to
 335                merge to avoid overwriting local changes.
 336        resolveConflict::
 337                Advice shown by various commands when conflicts
 338                prevent the operation from being performed.
 339        implicitIdentity::
 340                Advice on how to set your identity configuration when
 341                your information is guessed from the system username and
 342                domain name.
 343        detachedHead::
 344                Advice shown when you used linkgit:git-checkout[1] to
 345                move to the detach HEAD state, to instruct how to create
 346                a local branch after the fact.
 347        checkoutAmbiguousRemoteBranchName::
 348                Advice shown when the argument to
 349                linkgit:git-checkout[1] ambiguously resolves to a
 350                remote tracking branch on more than one remote in
 351                situations where an unambiguous argument would have
 352                otherwise caused a remote-tracking branch to be
 353                checked out. See the `checkout.defaultRemote`
 354                configuration variable for how to set a given remote
 355                to used by default in some situations where this
 356                advice would be printed.
 357        amWorkDir::
 358                Advice that shows the location of the patch file when
 359                linkgit:git-am[1] fails to apply it.
 360        rmHints::
 361                In case of failure in the output of linkgit:git-rm[1],
 362                show directions on how to proceed from the current state.
 363        addEmbeddedRepo::
 364                Advice on what to do when you've accidentally added one
 365                git repo inside of another.
 366        ignoredHook::
 367                Advice shown if a hook is ignored because the hook is not
 368                set as executable.
 369        waitingForEditor::
 370                Print a message to the terminal whenever Git is waiting for
 371                editor input from the user.
 372--
 373
 374core.fileMode::
 375        Tells Git if the executable bit of files in the working tree
 376        is to be honored.
 377+
 378Some filesystems lose the executable bit when a file that is
 379marked as executable is checked out, or checks out a
 380non-executable file with executable bit on.
 381linkgit:git-clone[1] or linkgit:git-init[1] probe the filesystem
 382to see if it handles the executable bit correctly
 383and this variable is automatically set as necessary.
 384+
 385A repository, however, may be on a filesystem that handles
 386the filemode correctly, and this variable is set to 'true'
 387when created, but later may be made accessible from another
 388environment that loses the filemode (e.g. exporting ext4 via
 389CIFS mount, visiting a Cygwin created repository with
 390Git for Windows or Eclipse).
 391In such a case it may be necessary to set this variable to 'false'.
 392See linkgit:git-update-index[1].
 393+
 394The default is true (when core.filemode is not specified in the config file).
 395
 396core.hideDotFiles::
 397        (Windows-only) If true, mark newly-created directories and files whose
 398        name starts with a dot as hidden.  If 'dotGitOnly', only the `.git/`
 399        directory is hidden, but no other files starting with a dot.  The
 400        default mode is 'dotGitOnly'.
 401
 402core.ignoreCase::
 403        Internal variable which enables various workarounds to enable
 404        Git to work better on filesystems that are not case sensitive,
 405        like APFS, HFS+, FAT, NTFS, etc. For example, if a directory listing
 406        finds "makefile" when Git expects "Makefile", Git will assume
 407        it is really the same file, and continue to remember it as
 408        "Makefile".
 409+
 410The default is false, except linkgit:git-clone[1] or linkgit:git-init[1]
 411will probe and set core.ignoreCase true if appropriate when the repository
 412is created.
 413+
 414Git relies on the proper configuration of this variable for your operating
 415and file system. Modifying this value may result in unexpected behavior.
 416
 417core.precomposeUnicode::
 418        This option is only used by Mac OS implementation of Git.
 419        When core.precomposeUnicode=true, Git reverts the unicode decomposition
 420        of filenames done by Mac OS. This is useful when sharing a repository
 421        between Mac OS and Linux or Windows.
 422        (Git for Windows 1.7.10 or higher is needed, or Git under cygwin 1.7).
 423        When false, file names are handled fully transparent by Git,
 424        which is backward compatible with older versions of Git.
 425
 426core.protectHFS::
 427        If set to true, do not allow checkout of paths that would
 428        be considered equivalent to `.git` on an HFS+ filesystem.
 429        Defaults to `true` on Mac OS, and `false` elsewhere.
 430
 431core.protectNTFS::
 432        If set to true, do not allow checkout of paths that would
 433        cause problems with the NTFS filesystem, e.g. conflict with
 434        8.3 "short" names.
 435        Defaults to `true` on Windows, and `false` elsewhere.
 436
 437core.fsmonitor::
 438        If set, the value of this variable is used as a command which
 439        will identify all files that may have changed since the
 440        requested date/time. This information is used to speed up git by
 441        avoiding unnecessary processing of files that have not changed.
 442        See the "fsmonitor-watchman" section of linkgit:githooks[5].
 443
 444core.trustctime::
 445        If false, the ctime differences between the index and the
 446        working tree are ignored; useful when the inode change time
 447        is regularly modified by something outside Git (file system
 448        crawlers and some backup systems).
 449        See linkgit:git-update-index[1]. True by default.
 450
 451core.splitIndex::
 452        If true, the split-index feature of the index will be used.
 453        See linkgit:git-update-index[1]. False by default.
 454
 455core.untrackedCache::
 456        Determines what to do about the untracked cache feature of the
 457        index. It will be kept, if this variable is unset or set to
 458        `keep`. It will automatically be added if set to `true`. And
 459        it will automatically be removed, if set to `false`. Before
 460        setting it to `true`, you should check that mtime is working
 461        properly on your system.
 462        See linkgit:git-update-index[1]. `keep` by default.
 463
 464core.checkStat::
 465        When missing or is set to `default`, many fields in the stat
 466        structure are checked to detect if a file has been modified
 467        since Git looked at it.  When this configuration variable is
 468        set to `minimal`, sub-second part of mtime and ctime, the
 469        uid and gid of the owner of the file, the inode number (and
 470        the device number, if Git was compiled to use it), are
 471        excluded from the check among these fields, leaving only the
 472        whole-second part of mtime (and ctime, if `core.trustCtime`
 473        is set) and the filesize to be checked.
 474+
 475There are implementations of Git that do not leave usable values in
 476some fields (e.g. JGit); by excluding these fields from the
 477comparison, the `minimal` mode may help interoperability when the
 478same repository is used by these other systems at the same time.
 479
 480core.quotePath::
 481        Commands that output paths (e.g. 'ls-files', 'diff'), will
 482        quote "unusual" characters in the pathname by enclosing the
 483        pathname in double-quotes and escaping those characters with
 484        backslashes in the same way C escapes control characters (e.g.
 485        `\t` for TAB, `\n` for LF, `\\` for backslash) or bytes with
 486        values larger than 0x80 (e.g. octal `\302\265` for "micro" in
 487        UTF-8).  If this variable is set to false, bytes higher than
 488        0x80 are not considered "unusual" any more. Double-quotes,
 489        backslash and control characters are always escaped regardless
 490        of the setting of this variable.  A simple space character is
 491        not considered "unusual".  Many commands can output pathnames
 492        completely verbatim using the `-z` option. The default value
 493        is true.
 494
 495core.eol::
 496        Sets the line ending type to use in the working directory for
 497        files that have the `text` property set when core.autocrlf is false.
 498        Alternatives are 'lf', 'crlf' and 'native', which uses the platform's
 499        native line ending.  The default value is `native`.  See
 500        linkgit:gitattributes[5] for more information on end-of-line
 501        conversion.
 502
 503core.safecrlf::
 504        If true, makes Git check if converting `CRLF` is reversible when
 505        end-of-line conversion is active.  Git will verify if a command
 506        modifies a file in the work tree either directly or indirectly.
 507        For example, committing a file followed by checking out the
 508        same file should yield the original file in the work tree.  If
 509        this is not the case for the current setting of
 510        `core.autocrlf`, Git will reject the file.  The variable can
 511        be set to "warn", in which case Git will only warn about an
 512        irreversible conversion but continue the operation.
 513+
 514CRLF conversion bears a slight chance of corrupting data.
 515When it is enabled, Git will convert CRLF to LF during commit and LF to
 516CRLF during checkout.  A file that contains a mixture of LF and
 517CRLF before the commit cannot be recreated by Git.  For text
 518files this is the right thing to do: it corrects line endings
 519such that we have only LF line endings in the repository.
 520But for binary files that are accidentally classified as text the
 521conversion can corrupt data.
 522+
 523If you recognize such corruption early you can easily fix it by
 524setting the conversion type explicitly in .gitattributes.  Right
 525after committing you still have the original file in your work
 526tree and this file is not yet corrupted.  You can explicitly tell
 527Git that this file is binary and Git will handle the file
 528appropriately.
 529+
 530Unfortunately, the desired effect of cleaning up text files with
 531mixed line endings and the undesired effect of corrupting binary
 532files cannot be distinguished.  In both cases CRLFs are removed
 533in an irreversible way.  For text files this is the right thing
 534to do because CRLFs are line endings, while for binary files
 535converting CRLFs corrupts data.
 536+
 537Note, this safety check does not mean that a checkout will generate a
 538file identical to the original file for a different setting of
 539`core.eol` and `core.autocrlf`, but only for the current one.  For
 540example, a text file with `LF` would be accepted with `core.eol=lf`
 541and could later be checked out with `core.eol=crlf`, in which case the
 542resulting file would contain `CRLF`, although the original file
 543contained `LF`.  However, in both work trees the line endings would be
 544consistent, that is either all `LF` or all `CRLF`, but never mixed.  A
 545file with mixed line endings would be reported by the `core.safecrlf`
 546mechanism.
 547
 548core.autocrlf::
 549        Setting this variable to "true" is the same as setting
 550        the `text` attribute to "auto" on all files and core.eol to "crlf".
 551        Set to true if you want to have `CRLF` line endings in your
 552        working directory and the repository has LF line endings.
 553        This variable can be set to 'input',
 554        in which case no output conversion is performed.
 555
 556core.checkRoundtripEncoding::
 557        A comma and/or whitespace separated list of encodings that Git
 558        performs UTF-8 round trip checks on if they are used in an
 559        `working-tree-encoding` attribute (see linkgit:gitattributes[5]).
 560        The default value is `SHIFT-JIS`.
 561
 562core.symlinks::
 563        If false, symbolic links are checked out as small plain files that
 564        contain the link text. linkgit:git-update-index[1] and
 565        linkgit:git-add[1] will not change the recorded type to regular
 566        file. Useful on filesystems like FAT that do not support
 567        symbolic links.
 568+
 569The default is true, except linkgit:git-clone[1] or linkgit:git-init[1]
 570will probe and set core.symlinks false if appropriate when the repository
 571is created.
 572
 573core.gitProxy::
 574        A "proxy command" to execute (as 'command host port') instead
 575        of establishing direct connection to the remote server when
 576        using the Git protocol for fetching. If the variable value is
 577        in the "COMMAND for DOMAIN" format, the command is applied only
 578        on hostnames ending with the specified domain string. This variable
 579        may be set multiple times and is matched in the given order;
 580        the first match wins.
 581+
 582Can be overridden by the `GIT_PROXY_COMMAND` environment variable
 583(which always applies universally, without the special "for"
 584handling).
 585+
 586The special string `none` can be used as the proxy command to
 587specify that no proxy be used for a given domain pattern.
 588This is useful for excluding servers inside a firewall from
 589proxy use, while defaulting to a common proxy for external domains.
 590
 591core.sshCommand::
 592        If this variable is set, `git fetch` and `git push` will
 593        use the specified command instead of `ssh` when they need to
 594        connect to a remote system. The command is in the same form as
 595        the `GIT_SSH_COMMAND` environment variable and is overridden
 596        when the environment variable is set.
 597
 598core.ignoreStat::
 599        If true, Git will avoid using lstat() calls to detect if files have
 600        changed by setting the "assume-unchanged" bit for those tracked files
 601        which it has updated identically in both the index and working tree.
 602+
 603When files are modified outside of Git, the user will need to stage
 604the modified files explicitly (e.g. see 'Examples' section in
 605linkgit:git-update-index[1]).
 606Git will not normally detect changes to those files.
 607+
 608This is useful on systems where lstat() calls are very slow, such as
 609CIFS/Microsoft Windows.
 610+
 611False by default.
 612
 613core.preferSymlinkRefs::
 614        Instead of the default "symref" format for HEAD
 615        and other symbolic reference files, use symbolic links.
 616        This is sometimes needed to work with old scripts that
 617        expect HEAD to be a symbolic link.
 618
 619core.bare::
 620        If true this repository is assumed to be 'bare' and has no
 621        working directory associated with it.  If this is the case a
 622        number of commands that require a working directory will be
 623        disabled, such as linkgit:git-add[1] or linkgit:git-merge[1].
 624+
 625This setting is automatically guessed by linkgit:git-clone[1] or
 626linkgit:git-init[1] when the repository was created.  By default a
 627repository that ends in "/.git" is assumed to be not bare (bare =
 628false), while all other repositories are assumed to be bare (bare
 629= true).
 630
 631core.worktree::
 632        Set the path to the root of the working tree.
 633        If `GIT_COMMON_DIR` environment variable is set, core.worktree
 634        is ignored and not used for determining the root of working tree.
 635        This can be overridden by the `GIT_WORK_TREE` environment
 636        variable and the `--work-tree` command-line option.
 637        The value can be an absolute path or relative to the path to
 638        the .git directory, which is either specified by --git-dir
 639        or GIT_DIR, or automatically discovered.
 640        If --git-dir or GIT_DIR is specified but none of
 641        --work-tree, GIT_WORK_TREE and core.worktree is specified,
 642        the current working directory is regarded as the top level
 643        of your working tree.
 644+
 645Note that this variable is honored even when set in a configuration
 646file in a ".git" subdirectory of a directory and its value differs
 647from the latter directory (e.g. "/path/to/.git/config" has
 648core.worktree set to "/different/path"), which is most likely a
 649misconfiguration.  Running Git commands in the "/path/to" directory will
 650still use "/different/path" as the root of the work tree and can cause
 651confusion unless you know what you are doing (e.g. you are creating a
 652read-only snapshot of the same index to a location different from the
 653repository's usual working tree).
 654
 655core.logAllRefUpdates::
 656        Enable the reflog. Updates to a ref <ref> is logged to the file
 657        "`$GIT_DIR/logs/<ref>`", by appending the new and old
 658        SHA-1, the date/time and the reason of the update, but
 659        only when the file exists.  If this configuration
 660        variable is set to `true`, missing "`$GIT_DIR/logs/<ref>`"
 661        file is automatically created for branch heads (i.e. under
 662        `refs/heads/`), remote refs (i.e. under `refs/remotes/`),
 663        note refs (i.e. under `refs/notes/`), and the symbolic ref `HEAD`.
 664        If it is set to `always`, then a missing reflog is automatically
 665        created for any ref under `refs/`.
 666+
 667This information can be used to determine what commit
 668was the tip of a branch "2 days ago".
 669+
 670This value is true by default in a repository that has
 671a working directory associated with it, and false by
 672default in a bare repository.
 673
 674core.repositoryFormatVersion::
 675        Internal variable identifying the repository format and layout
 676        version.
 677
 678core.sharedRepository::
 679        When 'group' (or 'true'), the repository is made shareable between
 680        several users in a group (making sure all the files and objects are
 681        group-writable). When 'all' (or 'world' or 'everybody'), the
 682        repository will be readable by all users, additionally to being
 683        group-shareable. When 'umask' (or 'false'), Git will use permissions
 684        reported by umask(2). When '0xxx', where '0xxx' is an octal number,
 685        files in the repository will have this mode value. '0xxx' will override
 686        user's umask value (whereas the other options will only override
 687        requested parts of the user's umask value). Examples: '0660' will make
 688        the repo read/write-able for the owner and group, but inaccessible to
 689        others (equivalent to 'group' unless umask is e.g. '0022'). '0640' is a
 690        repository that is group-readable but not group-writable.
 691        See linkgit:git-init[1]. False by default.
 692
 693core.warnAmbiguousRefs::
 694        If true, Git will warn you if the ref name you passed it is ambiguous
 695        and might match multiple refs in the repository. True by default.
 696
 697core.compression::
 698        An integer -1..9, indicating a default compression level.
 699        -1 is the zlib default. 0 means no compression,
 700        and 1..9 are various speed/size tradeoffs, 9 being slowest.
 701        If set, this provides a default to other compression variables,
 702        such as `core.looseCompression` and `pack.compression`.
 703
 704core.looseCompression::
 705        An integer -1..9, indicating the compression level for objects that
 706        are not in a pack file. -1 is the zlib default. 0 means no
 707        compression, and 1..9 are various speed/size tradeoffs, 9 being
 708        slowest.  If not set,  defaults to core.compression.  If that is
 709        not set,  defaults to 1 (best speed).
 710
 711core.packedGitWindowSize::
 712        Number of bytes of a pack file to map into memory in a
 713        single mapping operation.  Larger window sizes may allow
 714        your system to process a smaller number of large pack files
 715        more quickly.  Smaller window sizes will negatively affect
 716        performance due to increased calls to the operating system's
 717        memory manager, but may improve performance when accessing
 718        a large number of large pack files.
 719+
 720Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
 721MiB on 32 bit platforms and 1 GiB on 64 bit platforms.  This should
 722be reasonable for all users/operating systems.  You probably do
 723not need to adjust this value.
 724+
 725Common unit suffixes of 'k', 'm', or 'g' are supported.
 726
 727core.packedGitLimit::
 728        Maximum number of bytes to map simultaneously into memory
 729        from pack files.  If Git needs to access more than this many
 730        bytes at once to complete an operation it will unmap existing
 731        regions to reclaim virtual address space within the process.
 732+
 733Default is 256 MiB on 32 bit platforms and 32 TiB (effectively
 734unlimited) on 64 bit platforms.
 735This should be reasonable for all users/operating systems, except on
 736the largest projects.  You probably do not need to adjust this value.
 737+
 738Common unit suffixes of 'k', 'm', or 'g' are supported.
 739
 740core.deltaBaseCacheLimit::
 741        Maximum number of bytes to reserve for caching base objects
 742        that may be referenced by multiple deltified objects.  By storing the
 743        entire decompressed base objects in a cache Git is able
 744        to avoid unpacking and decompressing frequently used base
 745        objects multiple times.
 746+
 747Default is 96 MiB on all platforms.  This should be reasonable
 748for all users/operating systems, except on the largest projects.
 749You probably do not need to adjust this value.
 750+
 751Common unit suffixes of 'k', 'm', or 'g' are supported.
 752
 753core.bigFileThreshold::
 754        Files larger than this size are stored deflated, without
 755        attempting delta compression.  Storing large files without
 756        delta compression avoids excessive memory usage, at the
 757        slight expense of increased disk usage. Additionally files
 758        larger than this size are always treated as binary.
 759+
 760Default is 512 MiB on all platforms.  This should be reasonable
 761for most projects as source code and other text files can still
 762be delta compressed, but larger binary media files won't be.
 763+
 764Common unit suffixes of 'k', 'm', or 'g' are supported.
 765
 766core.excludesFile::
 767        Specifies the pathname to the file that contains patterns to
 768        describe paths that are not meant to be tracked, in addition
 769        to '.gitignore' (per-directory) and '.git/info/exclude'.
 770        Defaults to `$XDG_CONFIG_HOME/git/ignore`.
 771        If `$XDG_CONFIG_HOME` is either not set or empty, `$HOME/.config/git/ignore`
 772        is used instead. See linkgit:gitignore[5].
 773
 774core.askPass::
 775        Some commands (e.g. svn and http interfaces) that interactively
 776        ask for a password can be told to use an external program given
 777        via the value of this variable. Can be overridden by the `GIT_ASKPASS`
 778        environment variable. If not set, fall back to the value of the
 779        `SSH_ASKPASS` environment variable or, failing that, a simple password
 780        prompt. The external program shall be given a suitable prompt as
 781        command-line argument and write the password on its STDOUT.
 782
 783core.attributesFile::
 784        In addition to '.gitattributes' (per-directory) and
 785        '.git/info/attributes', Git looks into this file for attributes
 786        (see linkgit:gitattributes[5]). Path expansions are made the same
 787        way as for `core.excludesFile`. Its default value is
 788        `$XDG_CONFIG_HOME/git/attributes`. If `$XDG_CONFIG_HOME` is either not
 789        set or empty, `$HOME/.config/git/attributes` is used instead.
 790
 791core.hooksPath::
 792        By default Git will look for your hooks in the
 793        '$GIT_DIR/hooks' directory. Set this to different path,
 794        e.g. '/etc/git/hooks', and Git will try to find your hooks in
 795        that directory, e.g. '/etc/git/hooks/pre-receive' instead of
 796        in '$GIT_DIR/hooks/pre-receive'.
 797+
 798The path can be either absolute or relative. A relative path is
 799taken as relative to the directory where the hooks are run (see
 800the "DESCRIPTION" section of linkgit:githooks[5]).
 801+
 802This configuration variable is useful in cases where you'd like to
 803centrally configure your Git hooks instead of configuring them on a
 804per-repository basis, or as a more flexible and centralized
 805alternative to having an `init.templateDir` where you've changed
 806default hooks.
 807
 808core.editor::
 809        Commands such as `commit` and `tag` that let you edit
 810        messages by launching an editor use the value of this
 811        variable when it is set, and the environment variable
 812        `GIT_EDITOR` is not set.  See linkgit:git-var[1].
 813
 814core.commentChar::
 815        Commands such as `commit` and `tag` that let you edit
 816        messages consider a line that begins with this character
 817        commented, and removes them after the editor returns
 818        (default '#').
 819+
 820If set to "auto", `git-commit` would select a character that is not
 821the beginning character of any line in existing commit messages.
 822
 823core.filesRefLockTimeout::
 824        The length of time, in milliseconds, to retry when trying to
 825        lock an individual reference. Value 0 means not to retry at
 826        all; -1 means to try indefinitely. Default is 100 (i.e.,
 827        retry for 100ms).
 828
 829core.packedRefsTimeout::
 830        The length of time, in milliseconds, to retry when trying to
 831        lock the `packed-refs` file. Value 0 means not to retry at
 832        all; -1 means to try indefinitely. Default is 1000 (i.e.,
 833        retry for 1 second).
 834
 835sequence.editor::
 836        Text editor used by `git rebase -i` for editing the rebase instruction file.
 837        The value is meant to be interpreted by the shell when it is used.
 838        It can be overridden by the `GIT_SEQUENCE_EDITOR` environment variable.
 839        When not configured the default commit message editor is used instead.
 840
 841core.pager::
 842        Text viewer for use by Git commands (e.g., 'less').  The value
 843        is meant to be interpreted by the shell.  The order of preference
 844        is the `$GIT_PAGER` environment variable, then `core.pager`
 845        configuration, then `$PAGER`, and then the default chosen at
 846        compile time (usually 'less').
 847+
 848When the `LESS` environment variable is unset, Git sets it to `FRX`
 849(if `LESS` environment variable is set, Git does not change it at
 850all).  If you want to selectively override Git's default setting
 851for `LESS`, you can set `core.pager` to e.g. `less -S`.  This will
 852be passed to the shell by Git, which will translate the final
 853command to `LESS=FRX less -S`. The environment does not set the
 854`S` option but the command line does, instructing less to truncate
 855long lines. Similarly, setting `core.pager` to `less -+F` will
 856deactivate the `F` option specified by the environment from the
 857command-line, deactivating the "quit if one screen" behavior of
 858`less`.  One can specifically activate some flags for particular
 859commands: for example, setting `pager.blame` to `less -S` enables
 860line truncation only for `git blame`.
 861+
 862Likewise, when the `LV` environment variable is unset, Git sets it
 863to `-c`.  You can override this setting by exporting `LV` with
 864another value or setting `core.pager` to `lv +c`.
 865
 866core.whitespace::
 867        A comma separated list of common whitespace problems to
 868        notice.  'git diff' will use `color.diff.whitespace` to
 869        highlight them, and 'git apply --whitespace=error' will
 870        consider them as errors.  You can prefix `-` to disable
 871        any of them (e.g. `-trailing-space`):
 872+
 873* `blank-at-eol` treats trailing whitespaces at the end of the line
 874  as an error (enabled by default).
 875* `space-before-tab` treats a space character that appears immediately
 876  before a tab character in the initial indent part of the line as an
 877  error (enabled by default).
 878* `indent-with-non-tab` treats a line that is indented with space
 879  characters instead of the equivalent tabs as an error (not enabled by
 880  default).
 881* `tab-in-indent` treats a tab character in the initial indent part of
 882  the line as an error (not enabled by default).
 883* `blank-at-eof` treats blank lines added at the end of file as an error
 884  (enabled by default).
 885* `trailing-space` is a short-hand to cover both `blank-at-eol` and
 886  `blank-at-eof`.
 887* `cr-at-eol` treats a carriage-return at the end of line as
 888  part of the line terminator, i.e. with it, `trailing-space`
 889  does not trigger if the character before such a carriage-return
 890  is not a whitespace (not enabled by default).
 891* `tabwidth=<n>` tells how many character positions a tab occupies; this
 892  is relevant for `indent-with-non-tab` and when Git fixes `tab-in-indent`
 893  errors. The default tab width is 8. Allowed values are 1 to 63.
 894
 895core.fsyncObjectFiles::
 896        This boolean will enable 'fsync()' when writing object files.
 897+
 898This is a total waste of time and effort on a filesystem that orders
 899data writes properly, but can be useful for filesystems that do not use
 900journalling (traditional UNIX filesystems) or that only journal metadata
 901and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback").
 902
 903core.preloadIndex::
 904        Enable parallel index preload for operations like 'git diff'
 905+
 906This can speed up operations like 'git diff' and 'git status' especially
 907on filesystems like NFS that have weak caching semantics and thus
 908relatively high IO latencies.  When enabled, Git will do the
 909index comparison to the filesystem data in parallel, allowing
 910overlapping IO's.  Defaults to true.
 911
 912core.createObject::
 913        You can set this to 'link', in which case a hardlink followed by
 914        a delete of the source are used to make sure that object creation
 915        will not overwrite existing objects.
 916+
 917On some file system/operating system combinations, this is unreliable.
 918Set this config setting to 'rename' there; However, This will remove the
 919check that makes sure that existing object files will not get overwritten.
 920
 921core.notesRef::
 922        When showing commit messages, also show notes which are stored in
 923        the given ref.  The ref must be fully qualified.  If the given
 924        ref does not exist, it is not an error but means that no
 925        notes should be printed.
 926+
 927This setting defaults to "refs/notes/commits", and it can be overridden by
 928the `GIT_NOTES_REF` environment variable.  See linkgit:git-notes[1].
 929
 930core.commitGraph::
 931        If true, then git will read the commit-graph file (if it exists)
 932        to parse the graph structure of commits. Defaults to false. See
 933        linkgit:git-commit-graph[1] for more information.
 934
 935core.useReplaceRefs::
 936        If set to `false`, behave as if the `--no-replace-objects`
 937        option was given on the command line. See linkgit:git[1] and
 938        linkgit:git-replace[1] for more information.
 939
 940core.sparseCheckout::
 941        Enable "sparse checkout" feature. See section "Sparse checkout" in
 942        linkgit:git-read-tree[1] for more information.
 943
 944core.abbrev::
 945        Set the length object names are abbreviated to.  If
 946        unspecified or set to "auto", an appropriate value is
 947        computed based on the approximate number of packed objects
 948        in your repository, which hopefully is enough for
 949        abbreviated object names to stay unique for some time.
 950        The minimum length is 4.
 951
 952add.ignoreErrors::
 953add.ignore-errors (deprecated)::
 954        Tells 'git add' to continue adding files when some files cannot be
 955        added due to indexing errors. Equivalent to the `--ignore-errors`
 956        option of linkgit:git-add[1].  `add.ignore-errors` is deprecated,
 957        as it does not follow the usual naming convention for configuration
 958        variables.
 959
 960alias.*::
 961        Command aliases for the linkgit:git[1] command wrapper - e.g.
 962        after defining "alias.last = cat-file commit HEAD", the invocation
 963        "git last" is equivalent to "git cat-file commit HEAD". To avoid
 964        confusion and troubles with script usage, aliases that
 965        hide existing Git commands are ignored. Arguments are split by
 966        spaces, the usual shell quoting and escaping is supported.
 967        A quote pair or a backslash can be used to quote them.
 968+
 969If the alias expansion is prefixed with an exclamation point,
 970it will be treated as a shell command.  For example, defining
 971"alias.new = !gitk --all --not ORIG_HEAD", the invocation
 972"git new" is equivalent to running the shell command
 973"gitk --all --not ORIG_HEAD".  Note that shell commands will be
 974executed from the top-level directory of a repository, which may
 975not necessarily be the current directory.
 976`GIT_PREFIX` is set as returned by running 'git rev-parse --show-prefix'
 977from the original current directory. See linkgit:git-rev-parse[1].
 978
 979am.keepcr::
 980        If true, git-am will call git-mailsplit for patches in mbox format
 981        with parameter `--keep-cr`. In this case git-mailsplit will
 982        not remove `\r` from lines ending with `\r\n`. Can be overridden
 983        by giving `--no-keep-cr` from the command line.
 984        See linkgit:git-am[1], linkgit:git-mailsplit[1].
 985
 986am.threeWay::
 987        By default, `git am` will fail if the patch does not apply cleanly. When
 988        set to true, this setting tells `git am` to fall back on 3-way merge if
 989        the patch records the identity of blobs it is supposed to apply to and
 990        we have those blobs available locally (equivalent to giving the `--3way`
 991        option from the command line). Defaults to `false`.
 992        See linkgit:git-am[1].
 993
 994apply.ignoreWhitespace::
 995        When set to 'change', tells 'git apply' to ignore changes in
 996        whitespace, in the same way as the `--ignore-space-change`
 997        option.
 998        When set to one of: no, none, never, false tells 'git apply' to
 999        respect all whitespace differences.
1000        See linkgit:git-apply[1].
1001
1002apply.whitespace::
1003        Tells 'git apply' how to handle whitespaces, in the same way
1004        as the `--whitespace` option. See linkgit:git-apply[1].
1005
1006blame.blankBoundary::
1007        Show blank commit object name for boundary commits in
1008        linkgit:git-blame[1]. This option defaults to false.
1009
1010blame.coloring::
1011        This determines the coloring scheme to be applied to blame
1012        output. It can be 'repeatedLines', 'highlightRecent',
1013        or 'none' which is the default.
1014
1015blame.date::
1016        Specifies the format used to output dates in linkgit:git-blame[1].
1017        If unset the iso format is used. For supported values,
1018        see the discussion of the `--date` option at linkgit:git-log[1].
1019
1020blame.showEmail::
1021        Show the author email instead of author name in linkgit:git-blame[1].
1022        This option defaults to false.
1023
1024blame.showRoot::
1025        Do not treat root commits as boundaries in linkgit:git-blame[1].
1026        This option defaults to false.
1027
1028branch.autoSetupMerge::
1029        Tells 'git branch' and 'git checkout' to set up new branches
1030        so that linkgit:git-pull[1] will appropriately merge from the
1031        starting point branch. Note that even if this option is not set,
1032        this behavior can be chosen per-branch using the `--track`
1033        and `--no-track` options. The valid settings are: `false` -- no
1034        automatic setup is done; `true` -- automatic setup is done when the
1035        starting point is a remote-tracking branch; `always` --
1036        automatic setup is done when the starting point is either a
1037        local branch or remote-tracking
1038        branch. This option defaults to true.
1039
1040branch.autoSetupRebase::
1041        When a new branch is created with 'git branch' or 'git checkout'
1042        that tracks another branch, this variable tells Git to set
1043        up pull to rebase instead of merge (see "branch.<name>.rebase").
1044        When `never`, rebase is never automatically set to true.
1045        When `local`, rebase is set to true for tracked branches of
1046        other local branches.
1047        When `remote`, rebase is set to true for tracked branches of
1048        remote-tracking branches.
1049        When `always`, rebase will be set to true for all tracking
1050        branches.
1051        See "branch.autoSetupMerge" for details on how to set up a
1052        branch to track another branch.
1053        This option defaults to never.
1054
1055branch.sort::
1056        This variable controls the sort ordering of branches when displayed by
1057        linkgit:git-branch[1]. Without the "--sort=<value>" option provided, the
1058        value of this variable will be used as the default.
1059        See linkgit:git-for-each-ref[1] field names for valid values.
1060
1061branch.<name>.remote::
1062        When on branch <name>, it tells 'git fetch' and 'git push'
1063        which remote to fetch from/push to.  The remote to push to
1064        may be overridden with `remote.pushDefault` (for all branches).
1065        The remote to push to, for the current branch, may be further
1066        overridden by `branch.<name>.pushRemote`.  If no remote is
1067        configured, or if you are not on any branch, it defaults to
1068        `origin` for fetching and `remote.pushDefault` for pushing.
1069        Additionally, `.` (a period) is the current local repository
1070        (a dot-repository), see `branch.<name>.merge`'s final note below.
1071
1072branch.<name>.pushRemote::
1073        When on branch <name>, it overrides `branch.<name>.remote` for
1074        pushing.  It also overrides `remote.pushDefault` for pushing
1075        from branch <name>.  When you pull from one place (e.g. your
1076        upstream) and push to another place (e.g. your own publishing
1077        repository), you would want to set `remote.pushDefault` to
1078        specify the remote to push to for all branches, and use this
1079        option to override it for a specific branch.
1080
1081branch.<name>.merge::
1082        Defines, together with branch.<name>.remote, the upstream branch
1083        for the given branch. It tells 'git fetch'/'git pull'/'git rebase' which
1084        branch to merge and can also affect 'git push' (see push.default).
1085        When in branch <name>, it tells 'git fetch' the default
1086        refspec to be marked for merging in FETCH_HEAD. The value is
1087        handled like the remote part of a refspec, and must match a
1088        ref which is fetched from the remote given by
1089        "branch.<name>.remote".
1090        The merge information is used by 'git pull' (which at first calls
1091        'git fetch') to lookup the default branch for merging. Without
1092        this option, 'git pull' defaults to merge the first refspec fetched.
1093        Specify multiple values to get an octopus merge.
1094        If you wish to setup 'git pull' so that it merges into <name> from
1095        another branch in the local repository, you can point
1096        branch.<name>.merge to the desired branch, and use the relative path
1097        setting `.` (a period) for branch.<name>.remote.
1098
1099branch.<name>.mergeOptions::
1100        Sets default options for merging into branch <name>. The syntax and
1101        supported options are the same as those of linkgit:git-merge[1], but
1102        option values containing whitespace characters are currently not
1103        supported.
1104
1105branch.<name>.rebase::
1106        When true, rebase the branch <name> on top of the fetched branch,
1107        instead of merging the default branch from the default remote when
1108        "git pull" is run. See "pull.rebase" for doing this in a non
1109        branch-specific manner.
1110+
1111When `merges`, pass the `--rebase-merges` option to 'git rebase'
1112so that the local merge commits are included in the rebase (see
1113linkgit:git-rebase[1] for details).
1114+
1115When preserve, also pass `--preserve-merges` along to 'git rebase'
1116so that locally committed merge commits will not be flattened
1117by running 'git pull'.
1118+
1119When the value is `interactive`, the rebase is run in interactive mode.
1120+
1121*NOTE*: this is a possibly dangerous operation; do *not* use
1122it unless you understand the implications (see linkgit:git-rebase[1]
1123for details).
1124
1125branch.<name>.description::
1126        Branch description, can be edited with
1127        `git branch --edit-description`. Branch description is
1128        automatically added in the format-patch cover letter or
1129        request-pull summary.
1130
1131browser.<tool>.cmd::
1132        Specify the command to invoke the specified browser. The
1133        specified command is evaluated in shell with the URLs passed
1134        as arguments. (See linkgit:git-web{litdd}browse[1].)
1135
1136browser.<tool>.path::
1137        Override the path for the given tool that may be used to
1138        browse HTML help (see `-w` option in linkgit:git-help[1]) or a
1139        working repository in gitweb (see linkgit:git-instaweb[1]).
1140
1141checkout.defaultRemote::
1142        When you run 'git checkout <something>' and only have one
1143        remote, it may implicitly fall back on checking out and
1144        tracking e.g. 'origin/<something>'. This stops working as soon
1145        as you have more than one remote with a '<something>'
1146        reference. This setting allows for setting the name of a
1147        preferred remote that should always win when it comes to
1148        disambiguation. The typical use-case is to set this to
1149        `origin`.
1150+
1151Currently this is used by linkgit:git-checkout[1] when 'git checkout
1152<something>' will checkout the '<something>' branch on another remote,
1153and by linkgit:git-worktree[1] when 'git worktree add' refers to a
1154remote branch. This setting might be used for other checkout-like
1155commands or functionality in the future.
1156
1157clean.requireForce::
1158        A boolean to make git-clean do nothing unless given -f,
1159        -i or -n.   Defaults to true.
1160
1161color.advice::
1162        A boolean to enable/disable color in hints (e.g. when a push
1163        failed, see `advice.*` for a list).  May be set to `always`,
1164        `false` (or `never`) or `auto` (or `true`), in which case colors
1165        are used only when the error output goes to a terminal. If
1166        unset, then the value of `color.ui` is used (`auto` by default).
1167
1168color.advice.hint::
1169        Use customized color for hints.
1170
1171color.blame.highlightRecent::
1172        This can be used to color the metadata of a blame line depending
1173        on age of the line.
1174+
1175This setting should be set to a comma-separated list of color and date settings,
1176starting and ending with a color, the dates should be set from oldest to newest.
1177The metadata will be colored given the colors if the the line was introduced
1178before the given timestamp, overwriting older timestamped colors.
1179+
1180Instead of an absolute timestamp relative timestamps work as well, e.g.
11812.weeks.ago is valid to address anything older than 2 weeks.
1182+
1183It defaults to 'blue,12 month ago,white,1 month ago,red', which colors
1184everything older than one year blue, recent changes between one month and
1185one year old are kept white, and lines introduced within the last month are
1186colored red.
1187
1188color.blame.repeatedLines::
1189        Use the customized color for the part of git-blame output that
1190        is repeated meta information per line (such as commit id,
1191        author name, date and timezone). Defaults to cyan.
1192
1193color.branch::
1194        A boolean to enable/disable color in the output of
1195        linkgit:git-branch[1]. May be set to `always`,
1196        `false` (or `never`) or `auto` (or `true`), in which case colors are used
1197        only when the output is to a terminal. If unset, then the
1198        value of `color.ui` is used (`auto` by default).
1199
1200color.branch.<slot>::
1201        Use customized color for branch coloration. `<slot>` is one of
1202        `current` (the current branch), `local` (a local branch),
1203        `remote` (a remote-tracking branch in refs/remotes/),
1204        `upstream` (upstream tracking branch), `plain` (other
1205        refs).
1206
1207color.diff::
1208        Whether to use ANSI escape sequences to add color to patches.
1209        If this is set to `always`, linkgit:git-diff[1],
1210        linkgit:git-log[1], and linkgit:git-show[1] will use color
1211        for all patches.  If it is set to `true` or `auto`, those
1212        commands will only use color when output is to the terminal.
1213        If unset, then the value of `color.ui` is used (`auto` by
1214        default).
1215+
1216This does not affect linkgit:git-format-patch[1] or the
1217'git-diff-{asterisk}' plumbing commands.  Can be overridden on the
1218command line with the `--color[=<when>]` option.
1219
1220color.diff.<slot>::
1221        Use customized color for diff colorization.  `<slot>` specifies
1222        which part of the patch to use the specified color, and is one
1223        of `context` (context text - `plain` is a historical synonym),
1224        `meta` (metainformation), `frag`
1225        (hunk header), 'func' (function in hunk header), `old` (removed lines),
1226        `new` (added lines), `commit` (commit headers), `whitespace`
1227        (highlighting whitespace errors), `oldMoved` (deleted lines),
1228        `newMoved` (added lines), `oldMovedDimmed`, `oldMovedAlternative`,
1229        `oldMovedAlternativeDimmed`, `newMovedDimmed`, `newMovedAlternative`
1230        `newMovedAlternativeDimmed` (See the '<mode>'
1231        setting of '--color-moved' in linkgit:git-diff[1] for details),
1232        `contextDimmed`, `oldDimmed`, `newDimmed`, `contextBold`,
1233        `oldBold`, and `newBold` (see linkgit:git-range-diff[1] for details).
1234
1235color.decorate.<slot>::
1236        Use customized color for 'git log --decorate' output.  `<slot>` is one
1237        of `branch`, `remoteBranch`, `tag`, `stash` or `HEAD` for local
1238        branches, remote-tracking branches, tags, stash and HEAD, respectively
1239        and `grafted` for grafted commits.
1240
1241color.grep::
1242        When set to `always`, always highlight matches.  When `false` (or
1243        `never`), never.  When set to `true` or `auto`, use color only
1244        when the output is written to the terminal.  If unset, then the
1245        value of `color.ui` is used (`auto` by default).
1246
1247color.grep.<slot>::
1248        Use customized color for grep colorization.  `<slot>` specifies which
1249        part of the line to use the specified color, and is one of
1250+
1251--
1252`context`;;
1253        non-matching text in context lines (when using `-A`, `-B`, or `-C`)
1254`filename`;;
1255        filename prefix (when not using `-h`)
1256`function`;;
1257        function name lines (when using `-p`)
1258`lineNumber`;;
1259        line number prefix (when using `-n`)
1260`column`;;
1261        column number prefix (when using `--column`)
1262`match`;;
1263        matching text (same as setting `matchContext` and `matchSelected`)
1264`matchContext`;;
1265        matching text in context lines
1266`matchSelected`;;
1267        matching text in selected lines
1268`selected`;;
1269        non-matching text in selected lines
1270`separator`;;
1271        separators between fields on a line (`:`, `-`, and `=`)
1272        and between hunks (`--`)
1273--
1274
1275color.interactive::
1276        When set to `always`, always use colors for interactive prompts
1277        and displays (such as those used by "git-add --interactive" and
1278        "git-clean --interactive"). When false (or `never`), never.
1279        When set to `true` or `auto`, use colors only when the output is
1280        to the terminal. If unset, then the value of `color.ui` is
1281        used (`auto` by default).
1282
1283color.interactive.<slot>::
1284        Use customized color for 'git add --interactive' and 'git clean
1285        --interactive' output. `<slot>` may be `prompt`, `header`, `help`
1286        or `error`, for four distinct types of normal output from
1287        interactive commands.
1288
1289color.pager::
1290        A boolean to enable/disable colored output when the pager is in
1291        use (default is true).
1292
1293color.push::
1294        A boolean to enable/disable color in push errors. May be set to
1295        `always`, `false` (or `never`) or `auto` (or `true`), in which
1296        case colors are used only when the error output goes to a terminal.
1297        If unset, then the value of `color.ui` is used (`auto` by default).
1298
1299color.push.error::
1300        Use customized color for push errors.
1301
1302color.remote::
1303        If set, keywords at the start of the line are highlighted. The
1304        keywords are "error", "warning", "hint" and "success", and are
1305        matched case-insensitively. May be set to `always`, `false` (or
1306        `never`) or `auto` (or `true`). If unset, then the value of
1307        `color.ui` is used (`auto` by default).
1308
1309color.remote.<slot>::
1310        Use customized color for each remote keyword. `<slot>` may be
1311        `hint`, `warning`, `success` or `error` which match the
1312        corresponding keyword.
1313
1314color.showBranch::
1315        A boolean to enable/disable color in the output of
1316        linkgit:git-show-branch[1]. May be set to `always`,
1317        `false` (or `never`) or `auto` (or `true`), in which case colors are used
1318        only when the output is to a terminal. If unset, then the
1319        value of `color.ui` is used (`auto` by default).
1320
1321color.status::
1322        A boolean to enable/disable color in the output of
1323        linkgit:git-status[1]. May be set to `always`,
1324        `false` (or `never`) or `auto` (or `true`), in which case colors are used
1325        only when the output is to a terminal. If unset, then the
1326        value of `color.ui` is used (`auto` by default).
1327
1328color.status.<slot>::
1329        Use customized color for status colorization. `<slot>` is
1330        one of `header` (the header text of the status message),
1331        `added` or `updated` (files which are added but not committed),
1332        `changed` (files which are changed but not added in the index),
1333        `untracked` (files which are not tracked by Git),
1334        `branch` (the current branch),
1335        `nobranch` (the color the 'no branch' warning is shown in, defaulting
1336        to red),
1337        `localBranch` or `remoteBranch` (the local and remote branch names,
1338        respectively, when branch and tracking information is displayed in the
1339        status short-format), or
1340        `unmerged` (files which have unmerged changes).
1341
1342color.transport::
1343        A boolean to enable/disable color when pushes are rejected. May be
1344        set to `always`, `false` (or `never`) or `auto` (or `true`), in which
1345        case colors are used only when the error output goes to a terminal.
1346        If unset, then the value of `color.ui` is used (`auto` by default).
1347
1348color.transport.rejected::
1349        Use customized color when a push was rejected.
1350
1351color.ui::
1352        This variable determines the default value for variables such
1353        as `color.diff` and `color.grep` that control the use of color
1354        per command family. Its scope will expand as more commands learn
1355        configuration to set a default for the `--color` option.  Set it
1356        to `false` or `never` if you prefer Git commands not to use
1357        color unless enabled explicitly with some other configuration
1358        or the `--color` option. Set it to `always` if you want all
1359        output not intended for machine consumption to use color, to
1360        `true` or `auto` (this is the default since Git 1.8.4) if you
1361        want such output to use color when written to the terminal.
1362
1363column.ui::
1364        Specify whether supported commands should output in columns.
1365        This variable consists of a list of tokens separated by spaces
1366        or commas:
1367+
1368These options control when the feature should be enabled
1369(defaults to 'never'):
1370+
1371--
1372`always`;;
1373        always show in columns
1374`never`;;
1375        never show in columns
1376`auto`;;
1377        show in columns if the output is to the terminal
1378--
1379+
1380These options control layout (defaults to 'column').  Setting any
1381of these implies 'always' if none of 'always', 'never', or 'auto' are
1382specified.
1383+
1384--
1385`column`;;
1386        fill columns before rows
1387`row`;;
1388        fill rows before columns
1389`plain`;;
1390        show in one column
1391--
1392+
1393Finally, these options can be combined with a layout option (defaults
1394to 'nodense'):
1395+
1396--
1397`dense`;;
1398        make unequal size columns to utilize more space
1399`nodense`;;
1400        make equal size columns
1401--
1402
1403column.branch::
1404        Specify whether to output branch listing in `git branch` in columns.
1405        See `column.ui` for details.
1406
1407column.clean::
1408        Specify the layout when list items in `git clean -i`, which always
1409        shows files and directories in columns. See `column.ui` for details.
1410
1411column.status::
1412        Specify whether to output untracked files in `git status` in columns.
1413        See `column.ui` for details.
1414
1415column.tag::
1416        Specify whether to output tag listing in `git tag` in columns.
1417        See `column.ui` for details.
1418
1419commit.cleanup::
1420        This setting overrides the default of the `--cleanup` option in
1421        `git commit`. See linkgit:git-commit[1] for details. Changing the
1422        default can be useful when you always want to keep lines that begin
1423        with comment character `#` in your log message, in which case you
1424        would do `git config commit.cleanup whitespace` (note that you will
1425        have to remove the help lines that begin with `#` in the commit log
1426        template yourself, if you do this).
1427
1428commit.gpgSign::
1429
1430        A boolean to specify whether all commits should be GPG signed.
1431        Use of this option when doing operations such as rebase can
1432        result in a large number of commits being signed. It may be
1433        convenient to use an agent to avoid typing your GPG passphrase
1434        several times.
1435
1436commit.status::
1437        A boolean to enable/disable inclusion of status information in the
1438        commit message template when using an editor to prepare the commit
1439        message.  Defaults to true.
1440
1441commit.template::
1442        Specify the pathname of a file to use as the template for
1443        new commit messages.
1444
1445commit.verbose::
1446        A boolean or int to specify the level of verbose with `git commit`.
1447        See linkgit:git-commit[1].
1448
1449credential.helper::
1450        Specify an external helper to be called when a username or
1451        password credential is needed; the helper may consult external
1452        storage to avoid prompting the user for the credentials. Note
1453        that multiple helpers may be defined. See linkgit:gitcredentials[7]
1454        for details.
1455
1456credential.useHttpPath::
1457        When acquiring credentials, consider the "path" component of an http
1458        or https URL to be important. Defaults to false. See
1459        linkgit:gitcredentials[7] for more information.
1460
1461credential.username::
1462        If no username is set for a network authentication, use this username
1463        by default. See credential.<context>.* below, and
1464        linkgit:gitcredentials[7].
1465
1466credential.<url>.*::
1467        Any of the credential.* options above can be applied selectively to
1468        some credentials. For example "credential.https://example.com.username"
1469        would set the default username only for https connections to
1470        example.com. See linkgit:gitcredentials[7] for details on how URLs are
1471        matched.
1472
1473credentialCache.ignoreSIGHUP::
1474        Tell git-credential-cache--daemon to ignore SIGHUP, instead of quitting.
1475
1476completion.commands::
1477        This is only used by git-completion.bash to add or remove
1478        commands from the list of completed commands. Normally only
1479        porcelain commands and a few select others are completed. You
1480        can add more commands, separated by space, in this
1481        variable. Prefixing the command with '-' will remove it from
1482        the existing list.
1483
1484include::diff-config.txt[]
1485
1486difftool.<tool>.path::
1487        Override the path for the given tool.  This is useful in case
1488        your tool is not in the PATH.
1489
1490difftool.<tool>.cmd::
1491        Specify the command to invoke the specified diff tool.
1492        The specified command is evaluated in shell with the following
1493        variables available:  'LOCAL' is set to the name of the temporary
1494        file containing the contents of the diff pre-image and 'REMOTE'
1495        is set to the name of the temporary file containing the contents
1496        of the diff post-image.
1497
1498difftool.prompt::
1499        Prompt before each invocation of the diff tool.
1500
1501fastimport.unpackLimit::
1502        If the number of objects imported by linkgit:git-fast-import[1]
1503        is below this limit, then the objects will be unpacked into
1504        loose object files.  However if the number of imported objects
1505        equals or exceeds this limit then the pack will be stored as a
1506        pack.  Storing the pack from a fast-import can make the import
1507        operation complete faster, especially on slow filesystems.  If
1508        not set, the value of `transfer.unpackLimit` is used instead.
1509
1510fetch.recurseSubmodules::
1511        This option can be either set to a boolean value or to 'on-demand'.
1512        Setting it to a boolean changes the behavior of fetch and pull to
1513        unconditionally recurse into submodules when set to true or to not
1514        recurse at all when set to false. When set to 'on-demand' (the default
1515        value), fetch and pull will only recurse into a populated submodule
1516        when its superproject retrieves a commit that updates the submodule's
1517        reference.
1518
1519fetch.fsckObjects::
1520        If it is set to true, git-fetch-pack will check all fetched
1521        objects. See `transfer.fsckObjects` for what's
1522        checked. Defaults to false. If not set, the value of
1523        `transfer.fsckObjects` is used instead.
1524
1525fetch.fsck.<msg-id>::
1526        Acts like `fsck.<msg-id>`, but is used by
1527        linkgit:git-fetch-pack[1] instead of linkgit:git-fsck[1]. See
1528        the `fsck.<msg-id>` documentation for details.
1529
1530fetch.fsck.skipList::
1531        Acts like `fsck.skipList`, but is used by
1532        linkgit:git-fetch-pack[1] instead of linkgit:git-fsck[1]. See
1533        the `fsck.skipList` documentation for details.
1534
1535fetch.unpackLimit::
1536        If the number of objects fetched over the Git native
1537        transfer is below this
1538        limit, then the objects will be unpacked into loose object
1539        files. However if the number of received objects equals or
1540        exceeds this limit then the received pack will be stored as
1541        a pack, after adding any missing delta bases.  Storing the
1542        pack from a push can make the push operation complete faster,
1543        especially on slow filesystems.  If not set, the value of
1544        `transfer.unpackLimit` is used instead.
1545
1546fetch.prune::
1547        If true, fetch will automatically behave as if the `--prune`
1548        option was given on the command line.  See also `remote.<name>.prune`
1549        and the PRUNING section of linkgit:git-fetch[1].
1550
1551fetch.pruneTags::
1552        If true, fetch will automatically behave as if the
1553        `refs/tags/*:refs/tags/*` refspec was provided when pruning,
1554        if not set already. This allows for setting both this option
1555        and `fetch.prune` to maintain a 1=1 mapping to upstream
1556        refs. See also `remote.<name>.pruneTags` and the PRUNING
1557        section of linkgit:git-fetch[1].
1558
1559fetch.output::
1560        Control how ref update status is printed. Valid values are
1561        `full` and `compact`. Default value is `full`. See section
1562        OUTPUT in linkgit:git-fetch[1] for detail.
1563
1564fetch.negotiationAlgorithm::
1565        Control how information about the commits in the local repository is
1566        sent when negotiating the contents of the packfile to be sent by the
1567        server. Set to "skipping" to use an algorithm that skips commits in an
1568        effort to converge faster, but may result in a larger-than-necessary
1569        packfile; The default is "default" which instructs Git to use the default algorithm
1570        that never skips commits (unless the server has acknowledged it or one
1571        of its descendants).
1572        Unknown values will cause 'git fetch' to error out.
1573+
1574See also the `--negotiation-tip` option for linkgit:git-fetch[1].
1575
1576format.attach::
1577        Enable multipart/mixed attachments as the default for
1578        'format-patch'.  The value can also be a double quoted string
1579        which will enable attachments as the default and set the
1580        value as the boundary.  See the --attach option in
1581        linkgit:git-format-patch[1].
1582
1583format.from::
1584        Provides the default value for the `--from` option to format-patch.
1585        Accepts a boolean value, or a name and email address.  If false,
1586        format-patch defaults to `--no-from`, using commit authors directly in
1587        the "From:" field of patch mails.  If true, format-patch defaults to
1588        `--from`, using your committer identity in the "From:" field of patch
1589        mails and including a "From:" field in the body of the patch mail if
1590        different.  If set to a non-boolean value, format-patch uses that
1591        value instead of your committer identity.  Defaults to false.
1592
1593format.numbered::
1594        A boolean which can enable or disable sequence numbers in patch
1595        subjects.  It defaults to "auto" which enables it only if there
1596        is more than one patch.  It can be enabled or disabled for all
1597        messages by setting it to "true" or "false".  See --numbered
1598        option in linkgit:git-format-patch[1].
1599
1600format.headers::
1601        Additional email headers to include in a patch to be submitted
1602        by mail.  See linkgit:git-format-patch[1].
1603
1604format.to::
1605format.cc::
1606        Additional recipients to include in a patch to be submitted
1607        by mail.  See the --to and --cc options in
1608        linkgit:git-format-patch[1].
1609
1610format.subjectPrefix::
1611        The default for format-patch is to output files with the '[PATCH]'
1612        subject prefix. Use this variable to change that prefix.
1613
1614format.signature::
1615        The default for format-patch is to output a signature containing
1616        the Git version number. Use this variable to change that default.
1617        Set this variable to the empty string ("") to suppress
1618        signature generation.
1619
1620format.signatureFile::
1621        Works just like format.signature except the contents of the
1622        file specified by this variable will be used as the signature.
1623
1624format.suffix::
1625        The default for format-patch is to output files with the suffix
1626        `.patch`. Use this variable to change that suffix (make sure to
1627        include the dot if you want it).
1628
1629format.pretty::
1630        The default pretty format for log/show/whatchanged command,
1631        See linkgit:git-log[1], linkgit:git-show[1],
1632        linkgit:git-whatchanged[1].
1633
1634format.thread::
1635        The default threading style for 'git format-patch'.  Can be
1636        a boolean value, or `shallow` or `deep`.  `shallow` threading
1637        makes every mail a reply to the head of the series,
1638        where the head is chosen from the cover letter, the
1639        `--in-reply-to`, and the first patch mail, in this order.
1640        `deep` threading makes every mail a reply to the previous one.
1641        A true boolean value is the same as `shallow`, and a false
1642        value disables threading.
1643
1644format.signOff::
1645        A boolean value which lets you enable the `-s/--signoff` option of
1646        format-patch by default. *Note:* Adding the Signed-off-by: line to a
1647        patch should be a conscious act and means that you certify you have
1648        the rights to submit this work under the same open source license.
1649        Please see the 'SubmittingPatches' document for further discussion.
1650
1651format.coverLetter::
1652        A boolean that controls whether to generate a cover-letter when
1653        format-patch is invoked, but in addition can be set to "auto", to
1654        generate a cover-letter only when there's more than one patch.
1655
1656format.outputDirectory::
1657        Set a custom directory to store the resulting files instead of the
1658        current working directory.
1659
1660format.useAutoBase::
1661        A boolean value which lets you enable the `--base=auto` option of
1662        format-patch by default.
1663
1664filter.<driver>.clean::
1665        The command which is used to convert the content of a worktree
1666        file to a blob upon checkin.  See linkgit:gitattributes[5] for
1667        details.
1668
1669filter.<driver>.smudge::
1670        The command which is used to convert the content of a blob
1671        object to a worktree file upon checkout.  See
1672        linkgit:gitattributes[5] for details.
1673
1674fsck.<msg-id>::
1675        During fsck git may find issues with legacy data which
1676        wouldn't be generated by current versions of git, and which
1677        wouldn't be sent over the wire if `transfer.fsckObjects` was
1678        set. This feature is intended to support working with legacy
1679        repositories containing such data.
1680+
1681Setting `fsck.<msg-id>` will be picked up by linkgit:git-fsck[1], but
1682to accept pushes of such data set `receive.fsck.<msg-id>` instead, or
1683to clone or fetch it set `fetch.fsck.<msg-id>`.
1684+
1685The rest of the documentation discusses `fsck.*` for brevity, but the
1686same applies for the corresponding `receive.fsck.*` and
1687`fetch.<msg-id>.*`. variables.
1688+
1689Unlike variables like `color.ui` and `core.editor` the
1690`receive.fsck.<msg-id>` and `fetch.fsck.<msg-id>` variables will not
1691fall back on the `fsck.<msg-id>` configuration if they aren't set. To
1692uniformly configure the same fsck settings in different circumstances
1693all three of them they must all set to the same values.
1694+
1695When `fsck.<msg-id>` is set, errors can be switched to warnings and
1696vice versa by configuring the `fsck.<msg-id>` setting where the
1697`<msg-id>` is the fsck message ID and the value is one of `error`,
1698`warn` or `ignore`. For convenience, fsck prefixes the error/warning
1699with the message ID, e.g. "missingEmail: invalid author/committer line
1700- missing email" means that setting `fsck.missingEmail = ignore` will
1701hide that issue.
1702+
1703In general, it is better to enumerate existing objects with problems
1704with `fsck.skipList`, instead of listing the kind of breakages these
1705problematic objects share to be ignored, as doing the latter will
1706allow new instances of the same breakages go unnoticed.
1707+
1708Setting an unknown `fsck.<msg-id>` value will cause fsck to die, but
1709doing the same for `receive.fsck.<msg-id>` and `fetch.fsck.<msg-id>`
1710will only cause git to warn.
1711
1712fsck.skipList::
1713        The path to a sorted list of object names (i.e. one SHA-1 per
1714        line) that are known to be broken in a non-fatal way and should
1715        be ignored. This feature is useful when an established project
1716        should be accepted despite early commits containing errors that
1717        can be safely ignored such as invalid committer email addresses.
1718        Note: corrupt objects cannot be skipped with this setting.
1719+
1720Like `fsck.<msg-id>` this variable has corresponding
1721`receive.fsck.skipList` and `fetch.fsck.skipList` variants.
1722+
1723Unlike variables like `color.ui` and `core.editor` the
1724`receive.fsck.skipList` and `fetch.fsck.skipList` variables will not
1725fall back on the `fsck.skipList` configuration if they aren't set. To
1726uniformly configure the same fsck settings in different circumstances
1727all three of them they must all set to the same values.
1728
1729gc.aggressiveDepth::
1730        The depth parameter used in the delta compression
1731        algorithm used by 'git gc --aggressive'.  This defaults
1732        to 50.
1733
1734gc.aggressiveWindow::
1735        The window size parameter used in the delta compression
1736        algorithm used by 'git gc --aggressive'.  This defaults
1737        to 250.
1738
1739gc.auto::
1740        When there are approximately more than this many loose
1741        objects in the repository, `git gc --auto` will pack them.
1742        Some Porcelain commands use this command to perform a
1743        light-weight garbage collection from time to time.  The
1744        default value is 6700.  Setting this to 0 disables it.
1745
1746gc.autoPackLimit::
1747        When there are more than this many packs that are not
1748        marked with `*.keep` file in the repository, `git gc
1749        --auto` consolidates them into one larger pack.  The
1750        default value is 50.  Setting this to 0 disables it.
1751
1752gc.autoDetach::
1753        Make `git gc --auto` return immediately and run in background
1754        if the system supports it. Default is true.
1755
1756gc.bigPackThreshold::
1757        If non-zero, all packs larger than this limit are kept when
1758        `git gc` is run. This is very similar to `--keep-base-pack`
1759        except that all packs that meet the threshold are kept, not
1760        just the base pack. Defaults to zero. Common unit suffixes of
1761        'k', 'm', or 'g' are supported.
1762+
1763Note that if the number of kept packs is more than gc.autoPackLimit,
1764this configuration variable is ignored, all packs except the base pack
1765will be repacked. After this the number of packs should go below
1766gc.autoPackLimit and gc.bigPackThreshold should be respected again.
1767
1768gc.writeCommitGraph::
1769        If true, then gc will rewrite the commit-graph file when
1770        linkgit:git-gc[1] is run. When using linkgit:git-gc[1]
1771        '--auto' the commit-graph will be updated if housekeeping is
1772        required. Default is false. See linkgit:git-commit-graph[1]
1773        for details.
1774
1775gc.logExpiry::
1776        If the file gc.log exists, then `git gc --auto` won't run
1777        unless that file is more than 'gc.logExpiry' old.  Default is
1778        "1.day".  See `gc.pruneExpire` for more ways to specify its
1779        value.
1780
1781gc.packRefs::
1782        Running `git pack-refs` in a repository renders it
1783        unclonable by Git versions prior to 1.5.1.2 over dumb
1784        transports such as HTTP.  This variable determines whether
1785        'git gc' runs `git pack-refs`. This can be set to `notbare`
1786        to enable it within all non-bare repos or it can be set to a
1787        boolean value.  The default is `true`.
1788
1789gc.pruneExpire::
1790        When 'git gc' is run, it will call 'prune --expire 2.weeks.ago'.
1791        Override the grace period with this config variable.  The value
1792        "now" may be used to disable this grace period and always prune
1793        unreachable objects immediately, or "never" may be used to
1794        suppress pruning.  This feature helps prevent corruption when
1795        'git gc' runs concurrently with another process writing to the
1796        repository; see the "NOTES" section of linkgit:git-gc[1].
1797
1798gc.worktreePruneExpire::
1799        When 'git gc' is run, it calls
1800        'git worktree prune --expire 3.months.ago'.
1801        This config variable can be used to set a different grace
1802        period. The value "now" may be used to disable the grace
1803        period and prune `$GIT_DIR/worktrees` immediately, or "never"
1804        may be used to suppress pruning.
1805
1806gc.reflogExpire::
1807gc.<pattern>.reflogExpire::
1808        'git reflog expire' removes reflog entries older than
1809        this time; defaults to 90 days. The value "now" expires all
1810        entries immediately, and "never" suppresses expiration
1811        altogether. With "<pattern>" (e.g.
1812        "refs/stash") in the middle the setting applies only to
1813        the refs that match the <pattern>.
1814
1815gc.reflogExpireUnreachable::
1816gc.<pattern>.reflogExpireUnreachable::
1817        'git reflog expire' removes reflog entries older than
1818        this time and are not reachable from the current tip;
1819        defaults to 30 days. The value "now" expires all entries
1820        immediately, and "never" suppresses expiration altogether.
1821        With "<pattern>" (e.g. "refs/stash")
1822        in the middle, the setting applies only to the refs that
1823        match the <pattern>.
1824
1825gc.rerereResolved::
1826        Records of conflicted merge you resolved earlier are
1827        kept for this many days when 'git rerere gc' is run.
1828        You can also use more human-readable "1.month.ago", etc.
1829        The default is 60 days.  See linkgit:git-rerere[1].
1830
1831gc.rerereUnresolved::
1832        Records of conflicted merge you have not resolved are
1833        kept for this many days when 'git rerere gc' is run.
1834        You can also use more human-readable "1.month.ago", etc.
1835        The default is 15 days.  See linkgit:git-rerere[1].
1836
1837gitcvs.commitMsgAnnotation::
1838        Append this string to each commit message. Set to empty string
1839        to disable this feature. Defaults to "via git-CVS emulator".
1840
1841gitcvs.enabled::
1842        Whether the CVS server interface is enabled for this repository.
1843        See linkgit:git-cvsserver[1].
1844
1845gitcvs.logFile::
1846        Path to a log file where the CVS server interface well... logs
1847        various stuff. See linkgit:git-cvsserver[1].
1848
1849gitcvs.usecrlfattr::
1850        If true, the server will look up the end-of-line conversion
1851        attributes for files to determine the `-k` modes to use. If
1852        the attributes force Git to treat a file as text,
1853        the `-k` mode will be left blank so CVS clients will
1854        treat it as text. If they suppress text conversion, the file
1855        will be set with '-kb' mode, which suppresses any newline munging
1856        the client might otherwise do. If the attributes do not allow
1857        the file type to be determined, then `gitcvs.allBinary` is
1858        used. See linkgit:gitattributes[5].
1859
1860gitcvs.allBinary::
1861        This is used if `gitcvs.usecrlfattr` does not resolve
1862        the correct '-kb' mode to use. If true, all
1863        unresolved files are sent to the client in
1864        mode '-kb'. This causes the client to treat them
1865        as binary files, which suppresses any newline munging it
1866        otherwise might do. Alternatively, if it is set to "guess",
1867        then the contents of the file are examined to decide if
1868        it is binary, similar to `core.autocrlf`.
1869
1870gitcvs.dbName::
1871        Database used by git-cvsserver to cache revision information
1872        derived from the Git repository. The exact meaning depends on the
1873        used database driver, for SQLite (which is the default driver) this
1874        is a filename. Supports variable substitution (see
1875        linkgit:git-cvsserver[1] for details). May not contain semicolons (`;`).
1876        Default: '%Ggitcvs.%m.sqlite'
1877
1878gitcvs.dbDriver::
1879        Used Perl DBI driver. You can specify any available driver
1880        for this here, but it might not work. git-cvsserver is tested
1881        with 'DBD::SQLite', reported to work with 'DBD::Pg', and
1882        reported *not* to work with 'DBD::mysql'. Experimental feature.
1883        May not contain double colons (`:`). Default: 'SQLite'.
1884        See linkgit:git-cvsserver[1].
1885
1886gitcvs.dbUser, gitcvs.dbPass::
1887        Database user and password. Only useful if setting `gitcvs.dbDriver`,
1888        since SQLite has no concept of database users and/or passwords.
1889        'gitcvs.dbUser' supports variable substitution (see
1890        linkgit:git-cvsserver[1] for details).
1891
1892gitcvs.dbTableNamePrefix::
1893        Database table name prefix.  Prepended to the names of any
1894        database tables used, allowing a single database to be used
1895        for several repositories.  Supports variable substitution (see
1896        linkgit:git-cvsserver[1] for details).  Any non-alphabetic
1897        characters will be replaced with underscores.
1898
1899All gitcvs variables except for `gitcvs.usecrlfattr` and
1900`gitcvs.allBinary` can also be specified as
1901'gitcvs.<access_method>.<varname>' (where 'access_method'
1902is one of "ext" and "pserver") to make them apply only for the given
1903access method.

1921
1922grep.lineNumber::
1923        If set to true, enable `-n` option by default.
1924
1925grep.column::
1926        If set to true, enable the `--column` option by default.
1927
1928grep.patternType::
1929        Set the default matching behavior. Using a value of 'basic', 'extended',
1930        'fixed', or 'perl' will enable the `--basic-regexp`, `--extended-regexp`,
1931        `--fixed-strings`, or `--perl-regexp` option accordingly, while the
1932        value 'default' will return to the default matching behavior.
1933
1934grep.extendedRegexp::
1935        If set to true, enable `--extended-regexp` option by default. This
1936        option is ignored when the `grep.patternType` option is set to a value
1937        other than 'default'.
1938
1939grep.threads::
1940        Number of grep worker threads to use.
1941        See `grep.threads` in linkgit:git-grep[1] for more information.
1942
1943grep.fallbackToNoIndex::
1944        If set to true, fall back to git grep --no-index if git grep
1945        is executed outside of a git repository.  Defaults to false.
1946
1947gpg.program::
1948        Use this custom program instead of "`gpg`" found on `$PATH` when
1949        making or verifying a PGP signature. The program must support the
1950        same command-line interface as GPG, namely, to verify a detached
1951        signature, "`gpg --verify $file - <$signature`" is run, and the
1952        program is expected to signal a good signature by exiting with
1953        code 0, and to generate an ASCII-armored detached signature, the
1954        standard input of "`gpg -bsau $key`" is fed with the contents to be
1955        signed, and the program is expected to send the result to its
1956        standard output.
1957
1958gpg.format::
1959        Specifies which key format to use when signing with `--gpg-sign`.
1960        Default is "openpgp" and another possible value is "x509".
1961
1962gpg.<format>.program::
1963        Use this to customize the program used for the signing format you
1964        chose. (see `gpg.program` and `gpg.format`) `gpg.program` can still
1965        be used as a legacy synonym for `gpg.openpgp.program`. The default
1966        value for `gpg.x509.program` is "gpgsm".
1967
1968gui.commitMsgWidth::
1969        Defines how wide the commit message window is in the
1970        linkgit:git-gui[1]. "75" is the default.
1971
1972gui.diffContext::
1973        Specifies how many context lines should be used in calls to diff
1974        made by the linkgit:git-gui[1]. The default is "5".
1975
1976gui.displayUntracked::
1977        Determines if linkgit:git-gui[1] shows untracked files
1978        in the file list. The default is "true".
1979
1980gui.encoding::
1981        Specifies the default encoding to use for displaying of
1982        file contents in linkgit:git-gui[1] and linkgit:gitk[1].
1983        It can be overridden by setting the 'encoding' attribute
1984        for relevant files (see linkgit:gitattributes[5]).
1985        If this option is not set, the tools default to the
1986        locale encoding.
1987
1988gui.matchTrackingBranch::
1989        Determines if new branches created with linkgit:git-gui[1] should
1990        default to tracking remote branches with matching names or
1991        not. Default: "false".
1992
1993gui.newBranchTemplate::
1994        Is used as suggested name when creating new branches using the
1995        linkgit:git-gui[1].
1996
1997gui.pruneDuringFetch::
1998        "true" if linkgit:git-gui[1] should prune remote-tracking branches when
1999        performing a fetch. The default value is "false".
2000
2001gui.trustmtime::
2002        Determines if linkgit:git-gui[1] should trust the file modification
2003        timestamp or not. By default the timestamps are not trusted.
2004
2005gui.spellingDictionary::
2006        Specifies the dictionary used for spell checking commit messages in
2007        the linkgit:git-gui[1]. When set to "none" spell checking is turned
2008        off.
2009
2010gui.fastCopyBlame::
2011        If true, 'git gui blame' uses `-C` instead of `-C -C` for original
2012        location detection. It makes blame significantly faster on huge
2013        repositories at the expense of less thorough copy detection.
2014
2015gui.copyBlameThreshold::
2016        Specifies the threshold to use in 'git gui blame' original location
2017        detection, measured in alphanumeric characters. See the
2018        linkgit:git-blame[1] manual for more information on copy detection.
2019
2020gui.blamehistoryctx::
2021        Specifies the radius of history context in days to show in
2022        linkgit:gitk[1] for the selected commit, when the `Show History
2023        Context` menu item is invoked from 'git gui blame'. If this
2024        variable is set to zero, the whole history is shown.
2025
2026guitool.<name>.cmd::
2027        Specifies the shell command line to execute when the corresponding item
2028        of the linkgit:git-gui[1] `Tools` menu is invoked. This option is
2029        mandatory for every tool. The command is executed from the root of
2030        the working directory, and in the environment it receives the name of
2031        the tool as `GIT_GUITOOL`, the name of the currently selected file as
2032        'FILENAME', and the name of the current branch as 'CUR_BRANCH' (if
2033        the head is detached, 'CUR_BRANCH' is empty).
2034
2035guitool.<name>.needsFile::
2036        Run the tool only if a diff is selected in the GUI. It guarantees
2037        that 'FILENAME' is not empty.
2038
2039guitool.<name>.noConsole::
2040        Run the command silently, without creating a window to display its
2041        output.
2042
2043guitool.<name>.noRescan::
2044        Don't rescan the working directory for changes after the tool
2045        finishes execution.
2046
2047guitool.<name>.confirm::
2048        Show a confirmation dialog before actually running the tool.
2049
2050guitool.<name>.argPrompt::
2051        Request a string argument from the user, and pass it to the tool
2052        through the `ARGS` environment variable. Since requesting an
2053        argument implies confirmation, the 'confirm' option has no effect
2054        if this is enabled. If the option is set to 'true', 'yes', or '1',
2055        the dialog uses a built-in generic prompt; otherwise the exact
2056        value of the variable is used.
2057
2058guitool.<name>.revPrompt::
2059        Request a single valid revision from the user, and set the
2060        `REVISION` environment variable. In other aspects this option
2061        is similar to 'argPrompt', and can be used together with it.
2062
2063guitool.<name>.revUnmerged::
2064        Show only unmerged branches in the 'revPrompt' subdialog.
2065        This is useful for tools similar to merge or rebase, but not
2066        for things like checkout or reset.
2067
2068guitool.<name>.title::
2069        Specifies the title to use for the prompt dialog. The default
2070        is the tool name.
2071
2072guitool.<name>.prompt::
2073        Specifies the general prompt string to display at the top of
2074        the dialog, before subsections for 'argPrompt' and 'revPrompt'.
2075        The default value includes the actual command.
2076
2077help.browser::
2078        Specify the browser that will be used to display help in the
2079        'web' format. See linkgit:git-help[1].
2080
2081help.format::
2082        Override the default help format used by linkgit:git-help[1].
2083        Values 'man', 'info', 'web' and 'html' are supported. 'man' is
2084        the default. 'web' and 'html' are the same.
2085
2086help.autoCorrect::
2087        Automatically correct and execute mistyped commands after
2088        waiting for the given number of deciseconds (0.1 sec). If more
2089        than one command can be deduced from the entered text, nothing
2090        will be executed.  If the value of this option is negative,
2091        the corrected command will be executed immediately. If the
2092        value is 0 - the command will be just shown but not executed.
2093        This is the default.
2094
2095help.htmlPath::
2096        Specify the path where the HTML documentation resides. File system paths
2097        and URLs are supported. HTML pages will be prefixed with this path when
2098        help is displayed in the 'web' format. This defaults to the documentation
2099        path of your Git installation.
2100
2101http.proxy::
2102        Override the HTTP proxy, normally configured using the 'http_proxy',
2103        'https_proxy', and 'all_proxy' environment variables (see `curl(1)`). In
2104        addition to the syntax understood by curl, it is possible to specify a
2105        proxy string with a user name but no password, in which case git will
2106        attempt to acquire one in the same way it does for other credentials. See
2107        linkgit:gitcredentials[7] for more information. The syntax thus is
2108        '[protocol://][user[:password]@]proxyhost[:port]'. This can be overridden
2109        on a per-remote basis; see remote.<name>.proxy
2110
2111http.proxyAuthMethod::
2112        Set the method with which to authenticate against the HTTP proxy. This
2113        only takes effect if the configured proxy string contains a user name part
2114        (i.e. is of the form 'user@host' or 'user@host:port'). This can be
2115        overridden on a per-remote basis; see `remote.<name>.proxyAuthMethod`.
2116        Both can be overridden by the `GIT_HTTP_PROXY_AUTHMETHOD` environment
2117        variable.  Possible values are:
2118+
2119--
2120* `anyauth` - Automatically pick a suitable authentication method. It is
2121  assumed that the proxy answers an unauthenticated request with a 407
2122  status code and one or more Proxy-authenticate headers with supported
2123  authentication methods. This is the default.
2124* `basic` - HTTP Basic authentication
2125* `digest` - HTTP Digest authentication; this prevents the password from being
2126  transmitted to the proxy in clear text
2127* `negotiate` - GSS-Negotiate authentication (compare the --negotiate option
2128  of `curl(1)`)
2129* `ntlm` - NTLM authentication (compare the --ntlm option of `curl(1)`)
2130--
2131
2132http.emptyAuth::
2133        Attempt authentication without seeking a username or password.  This
2134        can be used to attempt GSS-Negotiate authentication without specifying
2135        a username in the URL, as libcurl normally requires a username for
2136        authentication.
2137
2138http.delegation::
2139        Control GSSAPI credential delegation. The delegation is disabled
2140        by default in libcurl since version 7.21.7. Set parameter to tell
2141        the server what it is allowed to delegate when it comes to user
2142        credentials. Used with GSS/kerberos. Possible values are:
2143+
2144--
2145* `none` - Don't allow any delegation.
2146* `policy` - Delegates if and only if the OK-AS-DELEGATE flag is set in the
2147  Kerberos service ticket, which is a matter of realm policy.
2148* `always` - Unconditionally allow the server to delegate.
2149--
2150
2151
2152http.extraHeader::
2153        Pass an additional HTTP header when communicating with a server.  If
2154        more than one such entry exists, all of them are added as extra
2155        headers.  To allow overriding the settings inherited from the system
2156        config, an empty value will reset the extra headers to the empty list.
2157
2158http.cookieFile::
2159        The pathname of a file containing previously stored cookie lines,
2160        which should be used
2161        in the Git http session, if they match the server. The file format
2162        of the file to read cookies from should be plain HTTP headers or
2163        the Netscape/Mozilla cookie file format (see `curl(1)`).
2164        NOTE that the file specified with http.cookieFile is used only as
2165        input unless http.saveCookies is set.
2166
2167http.saveCookies::
2168        If set, store cookies received during requests to the file specified by
2169        http.cookieFile. Has no effect if http.cookieFile is unset.
2170
2171http.sslVersion::
2172        The SSL version to use when negotiating an SSL connection, if you
2173        want to force the default.  The available and default version
2174        depend on whether libcurl was built against NSS or OpenSSL and the
2175        particular configuration of the crypto library in use. Internally
2176        this sets the 'CURLOPT_SSL_VERSION' option; see the libcurl
2177        documentation for more details on the format of this option and
2178        for the ssl version supported. Actually the possible values of
2179        this option are:
2180
2181        - sslv2
2182        - sslv3
2183        - tlsv1
2184        - tlsv1.0
2185        - tlsv1.1
2186        - tlsv1.2
2187        - tlsv1.3
2188
2189+
2190Can be overridden by the `GIT_SSL_VERSION` environment variable.
2191To force git to use libcurl's default ssl version and ignore any
2192explicit http.sslversion option, set `GIT_SSL_VERSION` to the
2193empty string.
2194
2195http.sslCipherList::
2196  A list of SSL ciphers to use when negotiating an SSL connection.
2197  The available ciphers depend on whether libcurl was built against
2198  NSS or OpenSSL and the particular configuration of the crypto
2199  library in use.  Internally this sets the 'CURLOPT_SSL_CIPHER_LIST'
2200  option; see the libcurl documentation for more details on the format
2201  of this list.
2202+
2203Can be overridden by the `GIT_SSL_CIPHER_LIST` environment variable.
2204To force git to use libcurl's default cipher list and ignore any
2205explicit http.sslCipherList option, set `GIT_SSL_CIPHER_LIST` to the
2206empty string.
2207
2208http.sslVerify::
2209        Whether to verify the SSL certificate when fetching or pushing
2210        over HTTPS. Defaults to true. Can be overridden by the
2211        `GIT_SSL_NO_VERIFY` environment variable.
2212
2213http.sslCert::
2214        File containing the SSL certificate when fetching or pushing
2215        over HTTPS. Can be overridden by the `GIT_SSL_CERT` environment
2216        variable.
2217
2218http.sslKey::
2219        File containing the SSL private key when fetching or pushing
2220        over HTTPS. Can be overridden by the `GIT_SSL_KEY` environment
2221        variable.
2222
2223http.sslCertPasswordProtected::
2224        Enable Git's password prompt for the SSL certificate.  Otherwise
2225        OpenSSL will prompt the user, possibly many times, if the
2226        certificate or private key is encrypted.  Can be overridden by the
2227        `GIT_SSL_CERT_PASSWORD_PROTECTED` environment variable.
2228
2229http.sslCAInfo::
2230        File containing the certificates to verify the peer with when
2231        fetching or pushing over HTTPS. Can be overridden by the
2232        `GIT_SSL_CAINFO` environment variable.
2233
2234http.sslCAPath::
2235        Path containing files with the CA certificates to verify the peer
2236        with when fetching or pushing over HTTPS. Can be overridden
2237        by the `GIT_SSL_CAPATH` environment variable.
2238
2239http.pinnedpubkey::
2240        Public key of the https service. It may either be the filename of
2241        a PEM or DER encoded public key file or a string starting with
2242        'sha256//' followed by the base64 encoded sha256 hash of the
2243        public key. See also libcurl 'CURLOPT_PINNEDPUBLICKEY'. git will
2244        exit with an error if this option is set but not supported by
2245        cURL.
2246
2247http.sslTry::
2248        Attempt to use AUTH SSL/TLS and encrypted data transfers
2249        when connecting via regular FTP protocol. This might be needed
2250        if the FTP server requires it for security reasons or you wish
2251        to connect securely whenever remote FTP server supports it.
2252        Default is false since it might trigger certificate verification
2253        errors on misconfigured servers.
2254
2255http.maxRequests::
2256        How many HTTP requests to launch in parallel. Can be overridden
2257        by the `GIT_HTTP_MAX_REQUESTS` environment variable. Default is 5.
2258
2259http.minSessions::
2260        The number of curl sessions (counted across slots) to be kept across
2261        requests. They will not be ended with curl_easy_cleanup() until
2262        http_cleanup() is invoked. If USE_CURL_MULTI is not defined, this
2263        value will be capped at 1. Defaults to 1.
2264
2265http.postBuffer::
2266        Maximum size in bytes of the buffer used by smart HTTP
2267        transports when POSTing data to the remote system.
2268        For requests larger than this buffer size, HTTP/1.1 and
2269        Transfer-Encoding: chunked is used to avoid creating a
2270        massive pack file locally.  Default is 1 MiB, which is
2271        sufficient for most requests.
2272
2273http.lowSpeedLimit, http.lowSpeedTime::
2274        If the HTTP transfer speed is less than 'http.lowSpeedLimit'
2275        for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
2276        Can be overridden by the `GIT_HTTP_LOW_SPEED_LIMIT` and
2277        `GIT_HTTP_LOW_SPEED_TIME` environment variables.
2278
2279http.noEPSV::
2280        A boolean which disables using of EPSV ftp command by curl.
2281        This can helpful with some "poor" ftp servers which don't
2282        support EPSV mode. Can be overridden by the `GIT_CURL_FTP_NO_EPSV`
2283        environment variable. Default is false (curl will use EPSV).
2284
2285http.userAgent::
2286        The HTTP USER_AGENT string presented to an HTTP server.  The default
2287        value represents the version of the client Git such as git/1.7.1.
2288        This option allows you to override this value to a more common value
2289        such as Mozilla/4.0.  This may be necessary, for instance, if
2290        connecting through a firewall that restricts HTTP connections to a set
2291        of common USER_AGENT strings (but not including those like git/1.7.1).
2292        Can be overridden by the `GIT_HTTP_USER_AGENT` environment variable.
2293
2294http.followRedirects::
2295        Whether git should follow HTTP redirects. If set to `true`, git
2296        will transparently follow any redirect issued by a server it
2297        encounters. If set to `false`, git will treat all redirects as
2298        errors. If set to `initial`, git will follow redirects only for
2299        the initial request to a remote, but not for subsequent
2300        follow-up HTTP requests. Since git uses the redirected URL as
2301        the base for the follow-up requests, this is generally
2302        sufficient. The default is `initial`.
2303
2304http.<url>.*::
2305        Any of the http.* options above can be applied selectively to some URLs.
2306        For a config key to match a URL, each element of the config key is
2307        compared to that of the URL, in the following order:
2308+
2309--
2310. Scheme (e.g., `https` in `https://example.com/`). This field
2311  must match exactly between the config key and the URL.
2312
2313. Host/domain name (e.g., `example.com` in `https://example.com/`).
2314  This field must match between the config key and the URL. It is
2315  possible to specify a `*` as part of the host name to match all subdomains
2316  at this level. `https://*.example.com/` for example would match
2317  `https://foo.example.com/`, but not `https://foo.bar.example.com/`.
2318
2319. Port number (e.g., `8080` in `http://example.com:8080/`).
2320  This field must match exactly between the config key and the URL.
2321  Omitted port numbers are automatically converted to the correct
2322  default for the scheme before matching.
2323
2324. Path (e.g., `repo.git` in `https://example.com/repo.git`). The
2325  path field of the config key must match the path field of the URL
2326  either exactly or as a prefix of slash-delimited path elements.  This means
2327  a config key with path `foo/` matches URL path `foo/bar`.  A prefix can only
2328  match on a slash (`/`) boundary.  Longer matches take precedence (so a config
2329  key with path `foo/bar` is a better match to URL path `foo/bar` than a config
2330  key with just path `foo/`).
2331
2332. User name (e.g., `user` in `https://user@example.com/repo.git`). If
2333  the config key has a user name it must match the user name in the
2334  URL exactly. If the config key does not have a user name, that
2335  config key will match a URL with any user name (including none),
2336  but at a lower precedence than a config key with a user name.
2337--
2338+
2339The list above is ordered by decreasing precedence; a URL that matches
2340a config key's path is preferred to one that matches its user name. For example,
2341if the URL is `https://user@example.com/foo/bar` a config key match of
2342`https://example.com/foo` will be preferred over a config key match of
2343`https://user@example.com`.
2344+
2345All URLs are normalized before attempting any matching (the password part,
2346if embedded in the URL, is always ignored for matching purposes) so that
2347equivalent URLs that are simply spelled differently will match properly.
2348Environment variable settings always override any matches.  The URLs that are
2349matched against are those given directly to Git commands.  This means any URLs
2350visited as a result of a redirection do not participate in matching.
2351
2352ssh.variant::
2353        By default, Git determines the command line arguments to use
2354        based on the basename of the configured SSH command (configured
2355        using the environment variable `GIT_SSH` or `GIT_SSH_COMMAND` or
2356        the config setting `core.sshCommand`). If the basename is
2357        unrecognized, Git will attempt to detect support of OpenSSH
2358        options by first invoking the configured SSH command with the
2359        `-G` (print configuration) option and will subsequently use
2360        OpenSSH options (if that is successful) or no options besides
2361        the host and remote command (if it fails).
2362+
2363The config variable `ssh.variant` can be set to override this detection.
2364Valid values are `ssh` (to use OpenSSH options), `plink`, `putty`,
2365`tortoiseplink`, `simple` (no options except the host and remote command).
2366The default auto-detection can be explicitly requested using the value
2367`auto`.  Any other value is treated as `ssh`.  This setting can also be
2368overridden via the environment variable `GIT_SSH_VARIANT`.
2369+
2370The current command-line parameters used for each variant are as
2371follows:
2372+
2373--
2374
2375* `ssh` - [-p port] [-4] [-6] [-o option] [username@]host command
2376
2377* `simple` - [username@]host command
2378
2379* `plink` or `putty` - [-P port] [-4] [-6] [username@]host command
2380
2381* `tortoiseplink` - [-P port] [-4] [-6] -batch [username@]host command
2382
2383--
2384+
2385Except for the `simple` variant, command-line parameters are likely to
2386change as git gains new features.
2387
2388i18n.commitEncoding::
2389        Character encoding the commit messages are stored in; Git itself
2390        does not care per se, but this information is necessary e.g. when
2391        importing commits from emails or in the gitk graphical history
2392        browser (and possibly at other places in the future or in other
2393        porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.
2394
2395i18n.logOutputEncoding::
2396        Character encoding the commit messages are converted to when
2397        running 'git log' and friends.
2398
2399imap::
2400        The configuration variables in the 'imap' section are described
2401        in linkgit:git-imap-send[1].
2402
2403index.version::
2404        Specify the version with which new index files should be
2405        initialized.  This does not affect existing repositories.
2406
2407init.templateDir::
2408        Specify the directory from which templates will be copied.
2409        (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].)
2410
2411instaweb.browser::
2412        Specify the program that will be used to browse your working
2413        repository in gitweb. See linkgit:git-instaweb[1].
2414
2415instaweb.httpd::
2416        The HTTP daemon command-line to start gitweb on your working
2417        repository. See linkgit:git-instaweb[1].
2418
2419instaweb.local::
2420        If true the web server started by linkgit:git-instaweb[1] will
2421        be bound to the local IP (127.0.0.1).
2422
2423instaweb.modulePath::
2424        The default module path for linkgit:git-instaweb[1] to use
2425        instead of /usr/lib/apache2/modules.  Only used if httpd
2426        is Apache.
2427
2428instaweb.port::
2429        The port number to bind the gitweb httpd to. See
2430        linkgit:git-instaweb[1].
2431
2432interactive.singleKey::
2433        In interactive commands, allow the user to provide one-letter
2434        input with a single key (i.e., without hitting enter).
2435        Currently this is used by the `--patch` mode of
2436        linkgit:git-add[1], linkgit:git-checkout[1], linkgit:git-commit[1],
2437        linkgit:git-reset[1], and linkgit:git-stash[1]. Note that this
2438        setting is silently ignored if portable keystroke input
2439        is not available; requires the Perl module Term::ReadKey.
2440
2441interactive.diffFilter::
2442        When an interactive command (such as `git add --patch`) shows
2443        a colorized diff, git will pipe the diff through the shell
2444        command defined by this configuration variable. The command may
2445        mark up the diff further for human consumption, provided that it
2446        retains a one-to-one correspondence with the lines in the
2447        original diff. Defaults to disabled (no filtering).
2448
2449log.abbrevCommit::
2450        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
2451        linkgit:git-whatchanged[1] assume `--abbrev-commit`. You may
2452        override this option with `--no-abbrev-commit`.
2453
2454log.date::
2455        Set the default date-time mode for the 'log' command.
2456        Setting a value for log.date is similar to using 'git log''s
2457        `--date` option.  See linkgit:git-log[1] for details.
2458
2459log.decorate::
2460        Print out the ref names of any commits that are shown by the log
2461        command. If 'short' is specified, the ref name prefixes 'refs/heads/',
2462        'refs/tags/' and 'refs/remotes/' will not be printed. If 'full' is
2463        specified, the full ref name (including prefix) will be printed.
2464        If 'auto' is specified, then if the output is going to a terminal,
2465        the ref names are shown as if 'short' were given, otherwise no ref
2466        names are shown. This is the same as the `--decorate` option
2467        of the `git log`.
2468
2469log.follow::
2470        If `true`, `git log` will act as if the `--follow` option was used when
2471        a single <path> is given.  This has the same limitations as `--follow`,
2472        i.e. it cannot be used to follow multiple files and does not work well
2473        on non-linear history.
2474
2475log.graphColors::
2476        A list of colors, separated by commas, that can be used to draw
2477        history lines in `git log --graph`.
2478
2479log.showRoot::
2480        If true, the initial commit will be shown as a big creation event.
2481        This is equivalent to a diff against an empty tree.
2482        Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
2483        normally hide the root commit will now show it. True by default.
2484
2485log.showSignature::
2486        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
2487        linkgit:git-whatchanged[1] assume `--show-signature`.
2488
2489log.mailmap::
2490        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
2491        linkgit:git-whatchanged[1] assume `--use-mailmap`.
2492
2493mailinfo.scissors::
2494        If true, makes linkgit:git-mailinfo[1] (and therefore
2495        linkgit:git-am[1]) act by default as if the --scissors option
2496        was provided on the command-line. When active, this features
2497        removes everything from the message body before a scissors
2498        line (i.e. consisting mainly of ">8", "8<" and "-").
2499
2500mailmap.file::
2501        The location of an augmenting mailmap file. The default
2502        mailmap, located in the root of the repository, is loaded
2503        first, then the mailmap file pointed to by this variable.
2504        The location of the mailmap file may be in a repository
2505        subdirectory, or somewhere outside of the repository itself.
2506        See linkgit:git-shortlog[1] and linkgit:git-blame[1].
2507
2508mailmap.blob::
2509        Like `mailmap.file`, but consider the value as a reference to a
2510        blob in the repository. If both `mailmap.file` and
2511        `mailmap.blob` are given, both are parsed, with entries from
2512        `mailmap.file` taking precedence. In a bare repository, this
2513        defaults to `HEAD:.mailmap`. In a non-bare repository, it
2514        defaults to empty.
2515
2516man.viewer::
2517        Specify the programs that may be used to display help in the
2518        'man' format. See linkgit:git-help[1].
2519
2520man.<tool>.cmd::
2521        Specify the command to invoke the specified man viewer. The
2522        specified command is evaluated in shell with the man page
2523        passed as argument. (See linkgit:git-help[1].)
2524
2525man.<tool>.path::
2526        Override the path for the given tool that may be used to
2527        display help in the 'man' format. See linkgit:git-help[1].
2528
2529include::merge-config.txt[]
2530
2531mergetool.<tool>.path::
2532        Override the path for the given tool.  This is useful in case
2533        your tool is not in the PATH.
2534
2535mergetool.<tool>.cmd::
2536        Specify the command to invoke the specified merge tool.  The
2537        specified command is evaluated in shell with the following
2538        variables available: 'BASE' is the name of a temporary file
2539        containing the common base of the files to be merged, if available;
2540        'LOCAL' is the name of a temporary file containing the contents of
2541        the file on the current branch; 'REMOTE' is the name of a temporary
2542        file containing the contents of the file from the branch being
2543        merged; 'MERGED' contains the name of the file to which the merge
2544        tool should write the results of a successful merge.
2545
2546mergetool.<tool>.trustExitCode::
2547        For a custom merge command, specify whether the exit code of
2548        the merge command can be used to determine whether the merge was
2549        successful.  If this is not set to true then the merge target file
2550        timestamp is checked and the merge assumed to have been successful
2551        if the file has been updated, otherwise the user is prompted to
2552        indicate the success of the merge.
2553
2554mergetool.meld.hasOutput::
2555        Older versions of `meld` do not support the `--output` option.
2556        Git will attempt to detect whether `meld` supports `--output`
2557        by inspecting the output of `meld --help`.  Configuring
2558        `mergetool.meld.hasOutput` will make Git skip these checks and
2559        use the configured value instead.  Setting `mergetool.meld.hasOutput`
2560        to `true` tells Git to unconditionally use the `--output` option,
2561        and `false` avoids using `--output`.
2562
2563mergetool.keepBackup::
2564        After performing a merge, the original file with conflict markers
2565        can be saved as a file with a `.orig` extension.  If this variable
2566        is set to `false` then this file is not preserved.  Defaults to
2567        `true` (i.e. keep the backup files).
2568
2569mergetool.keepTemporaries::
2570        When invoking a custom merge tool, Git uses a set of temporary
2571        files to pass to the tool. If the tool returns an error and this
2572        variable is set to `true`, then these temporary files will be
2573        preserved, otherwise they will be removed after the tool has
2574        exited. Defaults to `false`.
2575
2576mergetool.writeToTemp::
2577        Git writes temporary 'BASE', 'LOCAL', and 'REMOTE' versions of
2578        conflicting files in the worktree by default.  Git will attempt
2579        to use a temporary directory for these files when set `true`.
2580        Defaults to `false`.
2581
2582mergetool.prompt::
2583        Prompt before each invocation of the merge resolution program.
2584
2585notes.mergeStrategy::
2586        Which merge strategy to choose by default when resolving notes
2587        conflicts.  Must be one of `manual`, `ours`, `theirs`, `union`, or
2588        `cat_sort_uniq`.  Defaults to `manual`.  See "NOTES MERGE STRATEGIES"
2589        section of linkgit:git-notes[1] for more information on each strategy.
2590
2591notes.<name>.mergeStrategy::
2592        Which merge strategy to choose when doing a notes merge into
2593        refs/notes/<name>.  This overrides the more general
2594        "notes.mergeStrategy".  See the "NOTES MERGE STRATEGIES" section in
2595        linkgit:git-notes[1] for more information on the available strategies.
2596
2597notes.displayRef::
2598        The (fully qualified) refname from which to show notes when
2599        showing commit messages.  The value of this variable can be set
2600        to a glob, in which case notes from all matching refs will be
2601        shown.  You may also specify this configuration variable
2602        several times.  A warning will be issued for refs that do not
2603        exist, but a glob that does not match any refs is silently
2604        ignored.
2605+
2606This setting can be overridden with the `GIT_NOTES_DISPLAY_REF`
2607environment variable, which must be a colon separated list of refs or
2608globs.
2609+
2610The effective value of "core.notesRef" (possibly overridden by
2611GIT_NOTES_REF) is also implicitly added to the list of refs to be
2612displayed.
2613
2614notes.rewrite.<command>::
2615        When rewriting commits with <command> (currently `amend` or
2616        `rebase`) and this variable is set to `true`, Git
2617        automatically copies your notes from the original to the
2618        rewritten commit.  Defaults to `true`, but see
2619        "notes.rewriteRef" below.
2620
2621notes.rewriteMode::
2622        When copying notes during a rewrite (see the
2623        "notes.rewrite.<command>" option), determines what to do if
2624        the target commit already has a note.  Must be one of
2625        `overwrite`, `concatenate`, `cat_sort_uniq`, or `ignore`.
2626        Defaults to `concatenate`.
2627+
2628This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
2629environment variable.
2630
2631notes.rewriteRef::
2632        When copying notes during a rewrite, specifies the (fully
2633        qualified) ref whose notes should be copied.  The ref may be a
2634        glob, in which case notes in all matching refs will be copied.
2635        You may also specify this configuration several times.
2636+
2637Does not have a default value; you must configure this variable to
2638enable note rewriting.  Set it to `refs/notes/commits` to enable
2639rewriting for the default commit notes.
2640+
2641This setting can be overridden with the `GIT_NOTES_REWRITE_REF`
2642environment variable, which must be a colon separated list of refs or
2643globs.
2644
2645pack.window::
2646        The size of the window used by linkgit:git-pack-objects[1] when no
2647        window size is given on the command line. Defaults to 10.
2648
2649pack.depth::
2650        The maximum delta depth used by linkgit:git-pack-objects[1] when no
2651        maximum depth is given on the command line. Defaults to 50.
2652        Maximum value is 4095.
2653
2654pack.windowMemory::
2655        The maximum size of memory that is consumed by each thread
2656        in linkgit:git-pack-objects[1] for pack window memory when
2657        no limit is given on the command line.  The value can be
2658        suffixed with "k", "m", or "g".  When left unconfigured (or
2659        set explicitly to 0), there will be no limit.
2660
2661pack.compression::
2662        An integer -1..9, indicating the compression level for objects
2663        in a pack file. -1 is the zlib default. 0 means no
2664        compression, and 1..9 are various speed/size tradeoffs, 9 being
2665        slowest.  If not set,  defaults to core.compression.  If that is
2666        not set,  defaults to -1, the zlib default, which is "a default
2667        compromise between speed and compression (currently equivalent
2668        to level 6)."
2669+
2670Note that changing the compression level will not automatically recompress
2671all existing objects. You can force recompression by passing the -F option
2672to linkgit:git-repack[1].
2673
2674pack.deltaCacheSize::
2675        The maximum memory in bytes used for caching deltas in
2676        linkgit:git-pack-objects[1] before writing them out to a pack.
2677        This cache is used to speed up the writing object phase by not
2678        having to recompute the final delta result once the best match
2679        for all objects is found.  Repacking large repositories on machines
2680        which are tight with memory might be badly impacted by this though,
2681        especially if this cache pushes the system into swapping.
2682        A value of 0 means no limit. The smallest size of 1 byte may be
2683        used to virtually disable this cache. Defaults to 256 MiB.
2684
2685pack.deltaCacheLimit::
2686        The maximum size of a delta, that is cached in
2687        linkgit:git-pack-objects[1]. This cache is used to speed up the
2688        writing object phase by not having to recompute the final delta
2689        result once the best match for all objects is found.
2690        Defaults to 1000. Maximum value is 65535.
2691
2692pack.threads::
2693        Specifies the number of threads to spawn when searching for best
2694        delta matches.  This requires that linkgit:git-pack-objects[1]
2695        be compiled with pthreads otherwise this option is ignored with a
2696        warning. This is meant to reduce packing time on multiprocessor
2697        machines. The required amount of memory for the delta search window
2698        is however multiplied by the number of threads.
2699        Specifying 0 will cause Git to auto-detect the number of CPU's
2700        and set the number of threads accordingly.
2701
2702pack.indexVersion::
2703        Specify the default pack index version.  Valid values are 1 for
2704        legacy pack index used by Git versions prior to 1.5.2, and 2 for
2705        the new pack index with capabilities for packs larger than 4 GB
2706        as well as proper protection against the repacking of corrupted
2707        packs.  Version 2 is the default.  Note that version 2 is enforced
2708        and this config option ignored whenever the corresponding pack is
2709        larger than 2 GB.
2710+
2711If you have an old Git that does not understand the version 2 `*.idx` file,
2712cloning or fetching over a non native protocol (e.g. "http")
2713that will copy both `*.pack` file and corresponding `*.idx` file from the
2714other side may give you a repository that cannot be accessed with your
2715older version of Git. If the `*.pack` file is smaller than 2 GB, however,
2716you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
2717the `*.idx` file.
2718
2719pack.packSizeLimit::
2720        The maximum size of a pack.  This setting only affects
2721        packing to a file when repacking, i.e. the git:// protocol
2722        is unaffected.  It can be overridden by the `--max-pack-size`
2723        option of linkgit:git-repack[1].  Reaching this limit results
2724        in the creation of multiple packfiles; which in turn prevents
2725        bitmaps from being created.
2726        The minimum size allowed is limited to 1 MiB.
2727        The default is unlimited.
2728        Common unit suffixes of 'k', 'm', or 'g' are
2729        supported.
2730
2731pack.useBitmaps::
2732        When true, git will use pack bitmaps (if available) when packing
2733        to stdout (e.g., during the server side of a fetch). Defaults to
2734        true. You should not generally need to turn this off unless
2735        you are debugging pack bitmaps.
2736
2737pack.writeBitmaps (deprecated)::
2738        This is a deprecated synonym for `repack.writeBitmaps`.
2739
2740pack.writeBitmapHashCache::
2741        When true, git will include a "hash cache" section in the bitmap
2742        index (if one is written). This cache can be used to feed git's
2743        delta heuristics, potentially leading to better deltas between
2744        bitmapped and non-bitmapped objects (e.g., when serving a fetch
2745        between an older, bitmapped pack and objects that have been
2746        pushed since the last gc). The downside is that it consumes 4
2747        bytes per object of disk space, and that JGit's bitmap
2748        implementation does not understand it, causing it to complain if
2749        Git and JGit are used on the same repository. Defaults to false.
2750
2751pager.<cmd>::
2752        If the value is boolean, turns on or off pagination of the
2753        output of a particular Git subcommand when writing to a tty.
2754        Otherwise, turns on pagination for the subcommand using the
2755        pager specified by the value of `pager.<cmd>`.  If `--paginate`
2756        or `--no-pager` is specified on the command line, it takes
2757        precedence over this option.  To disable pagination for all
2758        commands, set `core.pager` or `GIT_PAGER` to `cat`.
2759
2760pretty.<name>::
2761        Alias for a --pretty= format string, as specified in
2762        linkgit:git-log[1]. Any aliases defined here can be used just
2763        as the built-in pretty formats could. For example,
2764        running `git config pretty.changelog "format:* %H %s"`
2765        would cause the invocation `git log --pretty=changelog`
2766        to be equivalent to running `git log "--pretty=format:* %H %s"`.
2767        Note that an alias with the same name as a built-in format
2768        will be silently ignored.
2769
2770protocol.allow::
2771        If set, provide a user defined default policy for all protocols which
2772        don't explicitly have a policy (`protocol.<name>.allow`).  By default,
2773        if unset, known-safe protocols (http, https, git, ssh, file) have a
2774        default policy of `always`, known-dangerous protocols (ext) have a
2775        default policy of `never`, and all other protocols have a default
2776        policy of `user`.  Supported policies:
2777+
2778--
2779
2780* `always` - protocol is always able to be used.
2781
2782* `never` - protocol is never able to be used.
2783
2784* `user` - protocol is only able to be used when `GIT_PROTOCOL_FROM_USER` is
2785  either unset or has a value of 1.  This policy should be used when you want a
2786  protocol to be directly usable by the user but don't want it used by commands which
2787  execute clone/fetch/push commands without user input, e.g. recursive
2788  submodule initialization.
2789
2790--
2791
2792protocol.<name>.allow::
2793        Set a policy to be used by protocol `<name>` with clone/fetch/push
2794        commands. See `protocol.allow` above for the available policies.
2795+
2796The protocol names currently used by git are:
2797+
2798--
2799  - `file`: any local file-based path (including `file://` URLs,
2800    or local paths)
2801
2802  - `git`: the anonymous git protocol over a direct TCP
2803    connection (or proxy, if configured)
2804
2805  - `ssh`: git over ssh (including `host:path` syntax,
2806    `ssh://`, etc).
2807
2808  - `http`: git over http, both "smart http" and "dumb http".
2809    Note that this does _not_ include `https`; if you want to configure
2810    both, you must do so individually.
2811
2812  - any external helpers are named by their protocol (e.g., use
2813    `hg` to allow the `git-remote-hg` helper)
2814--
2815
2816protocol.version::
2817        Experimental. If set, clients will attempt to communicate with a
2818        server using the specified protocol version.  If unset, no
2819        attempt will be made by the client to communicate using a
2820        particular protocol version, this results in protocol version 0
2821        being used.
2822        Supported versions:
2823+
2824--
2825
2826* `0` - the original wire protocol.
2827
2828* `1` - the original wire protocol with the addition of a version string
2829  in the initial response from the server.
2830
2831--
2832
2833pull.ff::
2834        By default, Git does not create an extra merge commit when merging
2835        a commit that is a descendant of the current commit. Instead, the
2836        tip of the current branch is fast-forwarded. When set to `false`,
2837        this variable tells Git to create an extra merge commit in such
2838        a case (equivalent to giving the `--no-ff` option from the command
2839        line). When set to `only`, only such fast-forward merges are
2840        allowed (equivalent to giving the `--ff-only` option from the
2841        command line). This setting overrides `merge.ff` when pulling.
2842
2843pull.rebase::
2844        When true, rebase branches on top of the fetched branch, instead
2845        of merging the default branch from the default remote when "git
2846        pull" is run. See "branch.<name>.rebase" for setting this on a
2847        per-branch basis.
2848+
2849When `merges`, pass the `--rebase-merges` option to 'git rebase'
2850so that the local merge commits are included in the rebase (see
2851linkgit:git-rebase[1] for details).
2852+
2853When preserve, also pass `--preserve-merges` along to 'git rebase'
2854so that locally committed merge commits will not be flattened
2855by running 'git pull'.
2856+
2857When the value is `interactive`, the rebase is run in interactive mode.
2858+
2859*NOTE*: this is a possibly dangerous operation; do *not* use
2860it unless you understand the implications (see linkgit:git-rebase[1]
2861for details).
2862
2863pull.octopus::
2864        The default merge strategy to use when pulling multiple branches
2865        at once.
2866
2867pull.twohead::
2868        The default merge strategy to use when pulling a single branch.
2869
2870push.default::
2871        Defines the action `git push` should take if no refspec is
2872        explicitly given.  Different values are well-suited for
2873        specific workflows; for instance, in a purely central workflow
2874        (i.e. the fetch source is equal to the push destination),
2875        `upstream` is probably what you want.  Possible values are:
2876+
2877--
2878
2879* `nothing` - do not push anything (error out) unless a refspec is
2880  explicitly given. This is primarily meant for people who want to
2881  avoid mistakes by always being explicit.
2882
2883* `current` - push the current branch to update a branch with the same
2884  name on the receiving end.  Works in both central and non-central
2885  workflows.
2886
2887* `upstream` - push the current branch back to the branch whose
2888  changes are usually integrated into the current branch (which is
2889  called `@{upstream}`).  This mode only makes sense if you are
2890  pushing to the same repository you would normally pull from
2891  (i.e. central workflow).
2892
2893* `tracking` - This is a deprecated synonym for `upstream`.
2894
2895* `simple` - in centralized workflow, work like `upstream` with an
2896  added safety to refuse to push if the upstream branch's name is
2897  different from the local one.
2898+
2899When pushing to a remote that is different from the remote you normally
2900pull from, work as `current`.  This is the safest option and is suited
2901for beginners.
2902+
2903This mode has become the default in Git 2.0.
2904
2905* `matching` - push all branches having the same name on both ends.
2906  This makes the repository you are pushing to remember the set of
2907  branches that will be pushed out (e.g. if you always push 'maint'
2908  and 'master' there and no other branches, the repository you push
2909  to will have these two branches, and your local 'maint' and
2910  'master' will be pushed there).
2911+
2912To use this mode effectively, you have to make sure _all_ the
2913branches you would push out are ready to be pushed out before
2914running 'git push', as the whole point of this mode is to allow you
2915to push all of the branches in one go.  If you usually finish work
2916on only one branch and push out the result, while other branches are
2917unfinished, this mode is not for you.  Also this mode is not
2918suitable for pushing into a shared central repository, as other
2919people may add new branches there, or update the tip of existing
2920branches outside your control.
2921+
2922This used to be the default, but not since Git 2.0 (`simple` is the
2923new default).
2924
2925--
2926
2927push.followTags::
2928        If set to true enable `--follow-tags` option by default.  You
2929        may override this configuration at time of push by specifying
2930        `--no-follow-tags`.
2931
2932push.gpgSign::
2933        May be set to a boolean value, or the string 'if-asked'. A true
2934        value causes all pushes to be GPG signed, as if `--signed` is
2935        passed to linkgit:git-push[1]. The string 'if-asked' causes
2936        pushes to be signed if the server supports it, as if
2937        `--signed=if-asked` is passed to 'git push'. A false value may
2938        override a value from a lower-priority config file. An explicit
2939        command-line flag always overrides this config option.
2940
2941push.pushOption::
2942        When no `--push-option=<option>` argument is given from the
2943        command line, `git push` behaves as if each <value> of
2944        this variable is given as `--push-option=<value>`.
2945+
2946This is a multi-valued variable, and an empty value can be used in a
2947higher priority configuration file (e.g. `.git/config` in a
2948repository) to clear the values inherited from a lower priority
2949configuration files (e.g. `$HOME/.gitconfig`).
2950+
2951--
2952
2953Example:
2954
2955/etc/gitconfig
2956  push.pushoption = a
2957  push.pushoption = b
2958
2959~/.gitconfig
2960  push.pushoption = c
2961
2962repo/.git/config
2963  push.pushoption =
2964  push.pushoption = b
2965
2966This will result in only b (a and c are cleared).
2967
2968--
2969
2970push.recurseSubmodules::
2971        Make sure all submodule commits used by the revisions to be pushed
2972        are available on a remote-tracking branch. If the value is 'check'
2973        then Git will verify that all submodule commits that changed in the
2974        revisions to be pushed are available on at least one remote of the
2975        submodule. If any commits are missing, the push will be aborted and
2976        exit with non-zero status. If the value is 'on-demand' then all
2977        submodules that changed in the revisions to be pushed will be
2978        pushed. If on-demand was not able to push all necessary revisions
2979        it will also be aborted and exit with non-zero status. If the value
2980        is 'no' then default behavior of ignoring submodules when pushing
2981        is retained. You may override this configuration at time of push by
2982        specifying '--recurse-submodules=check|on-demand|no'.
2983
2984include::rebase-config.txt[]
2985
2986receive.advertiseAtomic::
2987        By default, git-receive-pack will advertise the atomic push
2988        capability to its clients. If you don't want to advertise this
2989        capability, set this variable to false.
2990
2991receive.advertisePushOptions::
2992        When set to true, git-receive-pack will advertise the push options
2993        capability to its clients. False by default.
2994
2995receive.autogc::
2996        By default, git-receive-pack will run "git-gc --auto" after
2997        receiving data from git-push and updating refs.  You can stop
2998        it by setting this variable to false.
2999
3000receive.certNonceSeed::
3001        By setting this variable to a string, `git receive-pack`
3002        will accept a `git push --signed` and verifies it by using
3003        a "nonce" protected by HMAC using this string as a secret
3004        key.
3005
3006receive.certNonceSlop::
3007        When a `git push --signed` sent a push certificate with a
3008        "nonce" that was issued by a receive-pack serving the same
3009        repository within this many seconds, export the "nonce"
3010        found in the certificate to `GIT_PUSH_CERT_NONCE` to the
3011        hooks (instead of what the receive-pack asked the sending
3012        side to include).  This may allow writing checks in
3013        `pre-receive` and `post-receive` a bit easier.  Instead of
3014        checking `GIT_PUSH_CERT_NONCE_SLOP` environment variable
3015        that records by how many seconds the nonce is stale to
3016        decide if they want to accept the certificate, they only
3017        can check `GIT_PUSH_CERT_NONCE_STATUS` is `OK`.
3018
3019receive.fsckObjects::
3020        If it is set to true, git-receive-pack will check all received
3021        objects. See `transfer.fsckObjects` for what's checked.
3022        Defaults to false. If not set, the value of
3023        `transfer.fsckObjects` is used instead.
3024
3025receive.fsck.<msg-id>::
3026        Acts like `fsck.<msg-id>`, but is used by
3027        linkgit:git-receive-pack[1] instead of
3028        linkgit:git-fsck[1]. See the `fsck.<msg-id>` documentation for
3029        details.
3030
3031receive.fsck.skipList::
3032        Acts like `fsck.skipList`, but is used by
3033        linkgit:git-receive-pack[1] instead of
3034        linkgit:git-fsck[1]. See the `fsck.skipList` documentation for
3035        details.
3036
3037receive.keepAlive::
3038        After receiving the pack from the client, `receive-pack` may
3039        produce no output (if `--quiet` was specified) while processing
3040        the pack, causing some networks to drop the TCP connection.
3041        With this option set, if `receive-pack` does not transmit
3042        any data in this phase for `receive.keepAlive` seconds, it will
3043        send a short keepalive packet.  The default is 5 seconds; set
3044        to 0 to disable keepalives entirely.
3045
3046receive.unpackLimit::
3047        If the number of objects received in a push is below this
3048        limit then the objects will be unpacked into loose object
3049        files. However if the number of received objects equals or
3050        exceeds this limit then the received pack will be stored as
3051        a pack, after adding any missing delta bases.  Storing the
3052        pack from a push can make the push operation complete faster,
3053        especially on slow filesystems.  If not set, the value of
3054        `transfer.unpackLimit` is used instead.
3055
3056receive.maxInputSize::
3057        If the size of the incoming pack stream is larger than this
3058        limit, then git-receive-pack will error out, instead of
3059        accepting the pack file. If not set or set to 0, then the size
3060        is unlimited.
3061
3062receive.denyDeletes::
3063        If set to true, git-receive-pack will deny a ref update that deletes
3064        the ref. Use this to prevent such a ref deletion via a push.
3065
3066receive.denyDeleteCurrent::
3067        If set to true, git-receive-pack will deny a ref update that
3068        deletes the currently checked out branch of a non-bare repository.
3069
3070receive.denyCurrentBranch::
3071        If set to true or "refuse", git-receive-pack will deny a ref update
3072        to the currently checked out branch of a non-bare repository.
3073        Such a push is potentially dangerous because it brings the HEAD
3074        out of sync with the index and working tree. If set to "warn",
3075        print a warning of such a push to stderr, but allow the push to
3076        proceed. If set to false or "ignore", allow such pushes with no
3077        message. Defaults to "refuse".
3078+
3079Another option is "updateInstead" which will update the working
3080tree if pushing into the current branch.  This option is
3081intended for synchronizing working directories when one side is not easily
3082accessible via interactive ssh (e.g. a live web site, hence the requirement
3083that the working directory be clean). This mode also comes in handy when
3084developing inside a VM to test and fix code on different Operating Systems.
3085+
3086By default, "updateInstead" will refuse the push if the working tree or
3087the index have any difference from the HEAD, but the `push-to-checkout`
3088hook can be used to customize this.  See linkgit:githooks[5].
3089
3090receive.denyNonFastForwards::
3091        If set to true, git-receive-pack will deny a ref update which is
3092        not a fast-forward. Use this to prevent such an update via a push,
3093        even if that push is forced. This configuration variable is
3094        set when initializing a shared repository.
3095
3096receive.hideRefs::
3097        This variable is the same as `transfer.hideRefs`, but applies
3098        only to `receive-pack` (and so affects pushes, but not fetches).
3099        An attempt to update or delete a hidden ref by `git push` is
3100        rejected.
3101
3102receive.updateServerInfo::
3103        If set to true, git-receive-pack will run git-update-server-info
3104        after receiving data from git-push and updating refs.
3105
3106receive.shallowUpdate::
3107        If set to true, .git/shallow can be updated when new refs
3108        require new shallow roots. Otherwise those refs are rejected.
3109
3110remote.pushDefault::
3111        The remote to push to by default.  Overrides
3112        `branch.<name>.remote` for all branches, and is overridden by
3113        `branch.<name>.pushRemote` for specific branches.
3114
3115remote.<name>.url::
3116        The URL of a remote repository.  See linkgit:git-fetch[1] or
3117        linkgit:git-push[1].
3118
3119remote.<name>.pushurl::
3120        The push URL of a remote repository.  See linkgit:git-push[1].
3121
3122remote.<name>.proxy::
3123        For remotes that require curl (http, https and ftp), the URL to
3124        the proxy to use for that remote.  Set to the empty string to
3125        disable proxying for that remote.
3126
3127remote.<name>.proxyAuthMethod::
3128        For remotes that require curl (http, https and ftp), the method to use for
3129        authenticating against the proxy in use (probably set in
3130        `remote.<name>.proxy`). See `http.proxyAuthMethod`.
3131
3132remote.<name>.fetch::
3133        The default set of "refspec" for linkgit:git-fetch[1]. See
3134        linkgit:git-fetch[1].
3135
3136remote.<name>.push::
3137        The default set of "refspec" for linkgit:git-push[1]. See
3138        linkgit:git-push[1].
3139
3140remote.<name>.mirror::
3141        If true, pushing to this remote will automatically behave
3142        as if the `--mirror` option was given on the command line.
3143
3144remote.<name>.skipDefaultUpdate::
3145        If true, this remote will be skipped by default when updating
3146        using linkgit:git-fetch[1] or the `update` subcommand of
3147        linkgit:git-remote[1].
3148
3149remote.<name>.skipFetchAll::
3150        If true, this remote will be skipped by default when updating
3151        using linkgit:git-fetch[1] or the `update` subcommand of
3152        linkgit:git-remote[1].
3153
3154remote.<name>.receivepack::
3155        The default program to execute on the remote side when pushing.  See
3156        option --receive-pack of linkgit:git-push[1].
3157
3158remote.<name>.uploadpack::
3159        The default program to execute on the remote side when fetching.  See
3160        option --upload-pack of linkgit:git-fetch-pack[1].
3161
3162remote.<name>.tagOpt::
3163        Setting this value to --no-tags disables automatic tag following when
3164        fetching from remote <name>. Setting it to --tags will fetch every
3165        tag from remote <name>, even if they are not reachable from remote
3166        branch heads. Passing these flags directly to linkgit:git-fetch[1] can
3167        override this setting. See options --tags and --no-tags of
3168        linkgit:git-fetch[1].
3169
3170remote.<name>.vcs::
3171        Setting this to a value <vcs> will cause Git to interact with
3172        the remote with the git-remote-<vcs> helper.
3173
3174remote.<name>.prune::
3175        When set to true, fetching from this remote by default will also
3176        remove any remote-tracking references that no longer exist on the
3177        remote (as if the `--prune` option was given on the command line).
3178        Overrides `fetch.prune` settings, if any.
3179
3180remote.<name>.pruneTags::
3181        When set to true, fetching from this remote by default will also
3182        remove any local tags that no longer exist on the remote if pruning
3183        is activated in general via `remote.<name>.prune`, `fetch.prune` or
3184        `--prune`. Overrides `fetch.pruneTags` settings, if any.
3185+
3186See also `remote.<name>.prune` and the PRUNING section of
3187linkgit:git-fetch[1].
3188
3189remotes.<group>::
3190        The list of remotes which are fetched by "git remote update
3191        <group>".  See linkgit:git-remote[1].
3192
3193repack.useDeltaBaseOffset::
3194        By default, linkgit:git-repack[1] creates packs that use
3195        delta-base offset. If you need to share your repository with
3196        Git older than version 1.4.4, either directly or via a dumb
3197        protocol such as http, then you need to set this option to
3198        "false" and repack. Access from old Git versions over the
3199        native protocol are unaffected by this option.
3200
3201repack.packKeptObjects::
3202        If set to true, makes `git repack` act as if
3203        `--pack-kept-objects` was passed. See linkgit:git-repack[1] for
3204        details. Defaults to `false` normally, but `true` if a bitmap
3205        index is being written (either via `--write-bitmap-index` or
3206        `repack.writeBitmaps`).
3207
3208repack.writeBitmaps::
3209        When true, git will write a bitmap index when packing all
3210        objects to disk (e.g., when `git repack -a` is run).  This
3211        index can speed up the "counting objects" phase of subsequent
3212        packs created for clones and fetches, at the cost of some disk
3213        space and extra time spent on the initial repack.  This has
3214        no effect if multiple packfiles are created.
3215        Defaults to false.
3216
3217rerere.autoUpdate::
3218        When set to true, `git-rerere` updates the index with the
3219        resulting contents after it cleanly resolves conflicts using
3220        previously recorded resolution.  Defaults to false.
3221
3222rerere.enabled::
3223        Activate recording of resolved conflicts, so that identical
3224        conflict hunks can be resolved automatically, should they be
3225        encountered again.  By default, linkgit:git-rerere[1] is
3226        enabled if there is an `rr-cache` directory under the
3227        `$GIT_DIR`, e.g. if "rerere" was previously used in the
3228        repository.
3229
3230sendemail.identity::
3231        A configuration identity. When given, causes values in the
3232        'sendemail.<identity>' subsection to take precedence over
3233        values in the 'sendemail' section. The default identity is
3234        the value of `sendemail.identity`.
3235
3236sendemail.smtpEncryption::
3237        See linkgit:git-send-email[1] for description.  Note that this
3238        setting is not subject to the 'identity' mechanism.
3239
3240sendemail.smtpssl (deprecated)::
3241        Deprecated alias for 'sendemail.smtpEncryption = ssl'.
3242
3243sendemail.smtpsslcertpath::
3244        Path to ca-certificates (either a directory or a single file).
3245        Set it to an empty string to disable certificate verification.
3246
3247sendemail.<identity>.*::
3248        Identity-specific versions of the 'sendemail.*' parameters
3249        found below, taking precedence over those when this
3250        identity is selected, through either the command-line or
3251        `sendemail.identity`.
3252
3253sendemail.aliasesFile::
3254sendemail.aliasFileType::
3255sendemail.annotate::
3256sendemail.bcc::
3257sendemail.cc::

3279        See linkgit:git-send-email[1] for description.
3280
3281sendemail.signedoffcc (deprecated)::
3282        Deprecated alias for `sendemail.signedoffbycc`.
3283
3284sendemail.smtpBatchSize::
3285        Number of messages to be sent per connection, after that a relogin
3286        will happen.  If the value is 0 or undefined, send all messages in
3287        one connection.
3288        See also the `--batch-size` option of linkgit:git-send-email[1].
3289
3290sendemail.smtpReloginDelay::
3291        Seconds wait before reconnecting to smtp server.
3292        See also the `--relogin-delay` option of linkgit:git-send-email[1].
3293
3294showbranch.default::
3295        The default set of branches for linkgit:git-show-branch[1].
3296        See linkgit:git-show-branch[1].
3297
3298splitIndex.maxPercentChange::
3299        When the split index feature is used, this specifies the
3300        percent of entries the split index can contain compared to the
3301        total number of entries in both the split index and the shared
3302        index before a new shared index is written.
3303        The value should be between 0 and 100. If the value is 0 then
3304        a new shared index is always written, if it is 100 a new
3305        shared index is never written.
3306        By default the value is 20, so a new shared index is written
3307        if the number of entries in the split index would be greater
3308        than 20 percent of the total number of entries.
3309        See linkgit:git-update-index[1].
3310
3311splitIndex.sharedIndexExpire::
3312        When the split index feature is used, shared index files that
3313        were not modified since the time this variable specifies will
3314        be removed when a new shared index file is created. The value
3315        "now" expires all entries immediately, and "never" suppresses
3316        expiration altogether.
3317        The default value is "2.weeks.ago".
3318        Note that a shared index file is considered modified (for the
3319        purpose of expiration) each time a new split-index file is
3320        either created based on it or read from it.
3321        See linkgit:git-update-index[1].
3322
3323status.relativePaths::
3324        By default, linkgit:git-status[1] shows paths relative to the
3325        current directory. Setting this variable to `false` shows paths
3326        relative to the repository root (this was the default for Git
3327        prior to v1.5.4).
3328
3329status.short::
3330        Set to true to enable --short by default in linkgit:git-status[1].
3331        The option --no-short takes precedence over this variable.
3332
3333status.branch::
3334        Set to true to enable --branch by default in linkgit:git-status[1].
3335        The option --no-branch takes precedence over this variable.
3336
3337status.displayCommentPrefix::
3338        If set to true, linkgit:git-status[1] will insert a comment
3339        prefix before each output line (starting with
3340        `core.commentChar`, i.e. `#` by default). This was the
3341        behavior of linkgit:git-status[1] in Git 1.8.4 and previous.
3342        Defaults to false.
3343
3344status.renameLimit::
3345        The number of files to consider when performing rename detection
3346        in linkgit:git-status[1] and linkgit:git-commit[1]. Defaults to
3347        the value of diff.renameLimit.
3348
3349status.renames::
3350        Whether and how Git detects renames in linkgit:git-status[1] and
3351        linkgit:git-commit[1] .  If set to "false", rename detection is
3352        disabled. If set to "true", basic rename detection is enabled.
3353        If set to "copies" or "copy", Git will detect copies, as well.
3354        Defaults to the value of diff.renames.
3355
3356status.showStash::
3357        If set to true, linkgit:git-status[1] will display the number of
3358        entries currently stashed away.
3359        Defaults to false.
3360
3361status.showUntrackedFiles::
3362        By default, linkgit:git-status[1] and linkgit:git-commit[1] show
3363        files which are not currently tracked by Git. Directories which
3364        contain only untracked files, are shown with the directory name
3365        only. Showing untracked files means that Git needs to lstat() all
3366        the files in the whole repository, which might be slow on some
3367        systems. So, this variable controls how the commands displays
3368        the untracked files. Possible values are:
3369+
3370--
3371* `no` - Show no untracked files.
3372* `normal` - Show untracked files and directories.
3373* `all` - Show also individual files in untracked directories.
3374--
3375+
3376If this variable is not specified, it defaults to 'normal'.
3377This variable can be overridden with the -u|--untracked-files option
3378of linkgit:git-status[1] and linkgit:git-commit[1].
3379
3380status.submoduleSummary::
3381        Defaults to false.
3382        If this is set to a non zero number or true (identical to -1 or an
3383        unlimited number), the submodule summary will be enabled and a
3384        summary of commits for modified submodules will be shown (see
3385        --summary-limit option of linkgit:git-submodule[1]). Please note
3386        that the summary output command will be suppressed for all
3387        submodules when `diff.ignoreSubmodules` is set to 'all' or only
3388        for those submodules where `submodule.<name>.ignore=all`. The only
3389        exception to that rule is that status and commit will show staged
3390        submodule changes. To
3391        also view the summary for ignored submodules you can either use
3392        the --ignore-submodules=dirty command-line option or the 'git
3393        submodule summary' command, which shows a similar output but does
3394        not honor these settings.
3395
3396stash.showPatch::
3397        If this is set to true, the `git stash show` command without an
3398        option will show the stash entry in patch form.  Defaults to false.
3399        See description of 'show' command in linkgit:git-stash[1].
3400
3401stash.showStat::
3402        If this is set to true, the `git stash show` command without an
3403        option will show diffstat of the stash entry.  Defaults to true.
3404        See description of 'show' command in linkgit:git-stash[1].
3405
3406submodule.<name>.url::
3407        The URL for a submodule. This variable is copied from the .gitmodules
3408        file to the git config via 'git submodule init'. The user can change
3409        the configured URL before obtaining the submodule via 'git submodule
3410        update'. If neither submodule.<name>.active or submodule.active are
3411        set, the presence of this variable is used as a fallback to indicate
3412        whether the submodule is of interest to git commands.
3413        See linkgit:git-submodule[1] and linkgit:gitmodules[5] for details.
3414
3415submodule.<name>.update::
3416        The method by which a submodule is updated by 'git submodule update',
3417        which is the only affected command, others such as
3418        'git checkout --recurse-submodules' are unaffected. It exists for
3419        historical reasons, when 'git submodule' was the only command to
3420        interact with submodules; settings like `submodule.active`
3421        and `pull.rebase` are more specific. It is populated by
3422        `git submodule init` from the linkgit:gitmodules[5] file.
3423        See description of 'update' command in linkgit:git-submodule[1].
3424
3425submodule.<name>.branch::
3426        The remote branch name for a submodule, used by `git submodule
3427        update --remote`.  Set this option to override the value found in
3428        the `.gitmodules` file.  See linkgit:git-submodule[1] and
3429        linkgit:gitmodules[5] for details.
3430
3431submodule.<name>.fetchRecurseSubmodules::
3432        This option can be used to control recursive fetching of this
3433        submodule. It can be overridden by using the --[no-]recurse-submodules
3434        command-line option to "git fetch" and "git pull".
3435        This setting will override that from in the linkgit:gitmodules[5]
3436        file.
3437
3438submodule.<name>.ignore::
3439        Defines under what circumstances "git status" and the diff family show
3440        a submodule as modified. When set to "all", it will never be considered
3441        modified (but it will nonetheless show up in the output of status and
3442        commit when it has been staged), "dirty" will ignore all changes
3443        to the submodules work tree and
3444        takes only differences between the HEAD of the submodule and the commit
3445        recorded in the superproject into account. "untracked" will additionally
3446        let submodules with modified tracked files in their work tree show up.
3447        Using "none" (the default when this option is not set) also shows
3448        submodules that have untracked files in their work tree as changed.
3449        This setting overrides any setting made in .gitmodules for this submodule,
3450        both settings can be overridden on the command line by using the
3451        "--ignore-submodules" option. The 'git submodule' commands are not
3452        affected by this setting.
3453
3454submodule.<name>.active::
3455        Boolean value indicating if the submodule is of interest to git
3456        commands.  This config option takes precedence over the
3457        submodule.active config option. See linkgit:gitsubmodules[7] for
3458        details.
3459
3460submodule.active::
3461        A repeated field which contains a pathspec used to match against a
3462        submodule's path to determine if the submodule is of interest to git
3463        commands. See linkgit:gitsubmodules[7] for details.
3464
3465submodule.recurse::
3466        Specifies if commands recurse into submodules by default. This
3467        applies to all commands that have a `--recurse-submodules` option,
3468        except `clone`.
3469        Defaults to false.
3470
3471submodule.fetchJobs::
3472        Specifies how many submodules are fetched/cloned at the same time.
3473        A positive integer allows up to that number of submodules fetched
3474        in parallel. A value of 0 will give some reasonable default.
3475        If unset, it defaults to 1.
3476
3477submodule.alternateLocation::
3478        Specifies how the submodules obtain alternates when submodules are
3479        cloned. Possible values are `no`, `superproject`.
3480        By default `no` is assumed, which doesn't add references. When the
3481        value is set to `superproject` the submodule to be cloned computes
3482        its alternates location relative to the superprojects alternate.
3483
3484submodule.alternateErrorStrategy::
3485        Specifies how to treat errors with the alternates for a submodule
3486        as computed via `submodule.alternateLocation`. Possible values are
3487        `ignore`, `info`, `die`. Default is `die`.
3488
3489tag.forceSignAnnotated::
3490        A boolean to specify whether annotated tags created should be GPG signed.
3491        If `--annotate` is specified on the command line, it takes
3492        precedence over this option.
3493
3494tag.sort::
3495        This variable controls the sort ordering of tags when displayed by
3496        linkgit:git-tag[1]. Without the "--sort=<value>" option provided, the
3497        value of this variable will be used as the default.
3498
3499tar.umask::
3500        This variable can be used to restrict the permission bits of
3501        tar archive entries.  The default is 0002, which turns off the
3502        world write bit.  The special value "user" indicates that the
3503        archiving user's umask will be used instead.  See umask(2) and
3504        linkgit:git-archive[1].
3505
3506transfer.fsckObjects::
3507        When `fetch.fsckObjects` or `receive.fsckObjects` are
3508        not set, the value of this variable is used instead.
3509        Defaults to false.
3510+
3511When set, the fetch or receive will abort in the case of a malformed
3512object or a link to a nonexistent object. In addition, various other
3513issues are checked for, including legacy issues (see `fsck.<msg-id>`),
3514and potential security issues like the existence of a `.GIT` directory
3515or a malicious `.gitmodules` file (see the release notes for v2.2.1
3516and v2.17.1 for details). Other sanity and security checks may be
3517added in future releases.
3518+
3519On the receiving side, failing fsckObjects will make those objects
3520unreachable, see "QUARANTINE ENVIRONMENT" in
3521linkgit:git-receive-pack[1]. On the fetch side, malformed objects will
3522instead be left unreferenced in the repository.
3523+
3524Due to the non-quarantine nature of the `fetch.fsckObjects`
3525implementation it can not be relied upon to leave the object store
3526clean like `receive.fsckObjects` can.
3527+
3528As objects are unpacked they're written to the object store, so there
3529can be cases where malicious objects get introduced even though the
3530"fetch" failed, only to have a subsequent "fetch" succeed because only
3531new incoming objects are checked, not those that have already been
3532written to the object store. That difference in behavior should not be
3533relied upon. In the future, such objects may be quarantined for
3534"fetch" as well.
3535+
3536For now, the paranoid need to find some way to emulate the quarantine
3537environment if they'd like the same protection as "push". E.g. in the
3538case of an internal mirror do the mirroring in two steps, one to fetch
3539the untrusted objects, and then do a second "push" (which will use the
3540quarantine) to another internal repo, and have internal clients
3541consume this pushed-to repository, or embargo internal fetches and
3542only allow them once a full "fsck" has run (and no new fetches have
3543happened in the meantime).
3544
3545transfer.hideRefs::
3546        String(s) `receive-pack` and `upload-pack` use to decide which
3547        refs to omit from their initial advertisements.  Use more than
3548        one definition to specify multiple prefix strings. A ref that is
3549        under the hierarchies listed in the value of this variable is
3550        excluded, and is hidden when responding to `git push` or `git
3551        fetch`.  See `receive.hideRefs` and `uploadpack.hideRefs` for
3552        program-specific versions of this config.
3553+
3554You may also include a `!` in front of the ref name to negate the entry,
3555explicitly exposing it, even if an earlier entry marked it as hidden.
3556If you have multiple hideRefs values, later entries override earlier ones
3557(and entries in more-specific config files override less-specific ones).
3558+
3559If a namespace is in use, the namespace prefix is stripped from each
3560reference before it is matched against `transfer.hiderefs` patterns.
3561For example, if `refs/heads/master` is specified in `transfer.hideRefs` and
3562the current namespace is `foo`, then `refs/namespaces/foo/refs/heads/master`
3563is omitted from the advertisements but `refs/heads/master` and
3564`refs/namespaces/bar/refs/heads/master` are still advertised as so-called
3565"have" lines. In order to match refs before stripping, add a `^` in front of
3566the ref name. If you combine `!` and `^`, `!` must be specified first.
3567+
3568Even if you hide refs, a client may still be able to steal the target
3569objects via the techniques described in the "SECURITY" section of the
3570linkgit:gitnamespaces[7] man page; it's best to keep private data in a
3571separate repository.
3572
3573transfer.unpackLimit::
3574        When `fetch.unpackLimit` or `receive.unpackLimit` are
3575        not set, the value of this variable is used instead.
3576        The default value is 100.
3577
3578uploadarchive.allowUnreachable::
3579        If true, allow clients to use `git archive --remote` to request
3580        any tree, whether reachable from the ref tips or not. See the
3581        discussion in the "SECURITY" section of
3582        linkgit:git-upload-archive[1] for more details. Defaults to
3583        `false`.
3584
3585uploadpack.hideRefs::
3586        This variable is the same as `transfer.hideRefs`, but applies
3587        only to `upload-pack` (and so affects only fetches, not pushes).
3588        An attempt to fetch a hidden ref by `git fetch` will fail.  See
3589        also `uploadpack.allowTipSHA1InWant`.

3591uploadpack.allowTipSHA1InWant::
3592        When `uploadpack.hideRefs` is in effect, allow `upload-pack`
3593        to accept a fetch request that asks for an object at the tip
3594        of a hidden ref (by default, such a request is rejected).
3595        See also `uploadpack.hideRefs`.  Even if this is false, a client
3596        may be able to steal objects via the techniques described in the
3597        "SECURITY" section of the linkgit:gitnamespaces[7] man page; it's
3598        best to keep private data in a separate repository.
3599
3600uploadpack.allowReachableSHA1InWant::
3601        Allow `upload-pack` to accept a fetch request that asks for an
3602        object that is reachable from any ref tip. However, note that
3603        calculating object reachability is computationally expensive.
3604        Defaults to `false`.  Even if this is false, a client may be able
3605        to steal objects via the techniques described in the "SECURITY"
3606        section of the linkgit:gitnamespaces[7] man page; it's best to
3607        keep private data in a separate repository.
3608
3609uploadpack.allowAnySHA1InWant::
3610        Allow `upload-pack` to accept a fetch request that asks for any
3611        object at all.
3612        Defaults to `false`.
3613
3614uploadpack.keepAlive::
3615        When `upload-pack` has started `pack-objects`, there may be a
3616        quiet period while `pack-objects` prepares the pack. Normally
3617        it would output progress information, but if `--quiet` was used
3618        for the fetch, `pack-objects` will output nothing at all until
3619        the pack data begins. Some clients and networks may consider
3620        the server to be hung and give up. Setting this option instructs
3621        `upload-pack` to send an empty keepalive packet every
3622        `uploadpack.keepAlive` seconds. Setting this option to 0
3623        disables keepalive packets entirely. The default is 5 seconds.
3624
3625uploadpack.packObjectsHook::
3626        If this option is set, when `upload-pack` would run
3627        `git pack-objects` to create a packfile for a client, it will
3628        run this shell command instead.  The `pack-objects` command and
3629        arguments it _would_ have run (including the `git pack-objects`
3630        at the beginning) are appended to the shell command. The stdin
3631        and stdout of the hook are treated as if `pack-objects` itself
3632        was run. I.e., `upload-pack` will feed input intended for
3633        `pack-objects` to the hook, and expects a completed packfile on
3634        stdout.
3635
3636uploadpack.allowFilter::
3637        If this option is set, `upload-pack` will support partial
3638        clone and partial fetch object filtering.
3639+
3640Note that this configuration variable is ignored if it is seen in the
3641repository-level config (this is a safety measure against fetching from
3642untrusted repositories).
3643
3644uploadpack.allowRefInWant::
3645        If this option is set, `upload-pack` will support the `ref-in-want`
3646        feature of the protocol version 2 `fetch` command.  This feature
3647        is intended for the benefit of load-balanced servers which may
3648        not have the same view of what OIDs their refs point to due to
3649        replication delay.
3650
3651url.<base>.insteadOf::
3652        Any URL that starts with this value will be rewritten to
3653        start, instead, with <base>. In cases where some site serves a
3654        large number of repositories, and serves them with multiple
3655        access methods, and some users need to use different access
3656        methods, this feature allows people to specify any of the
3657        equivalent URLs and have Git automatically rewrite the URL to
3658        the best alternative for the particular user, even for a
3659        never-before-seen repository on the site.  When more than one
3660        insteadOf strings match a given URL, the longest match is used.
3661+
3662Note that any protocol restrictions will be applied to the rewritten
3663URL. If the rewrite changes the URL to use a custom protocol or remote
3664helper, you may need to adjust the `protocol.*.allow` config to permit
3665the request.  In particular, protocols you expect to use for submodules
3666must be set to `always` rather than the default of `user`. See the
3667description of `protocol.allow` above.
3668
3669url.<base>.pushInsteadOf::
3670        Any URL that starts with this value will not be pushed to;
3671        instead, it will be rewritten to start with <base>, and the
3672        resulting URL will be pushed to. In cases where some site serves
3673        a large number of repositories, and serves them with multiple
3674        access methods, some of which do not allow push, this feature
3675        allows people to specify a pull-only URL and have Git
3676        automatically use an appropriate URL to push, even for a
3677        never-before-seen repository on the site.  When more than one
3678        pushInsteadOf strings match a given URL, the longest match is
3679        used.  If a remote has an explicit pushurl, Git will ignore this
3680        setting for that remote.
3681
3682user.email::
3683        Your email address to be recorded in any newly created commits.
3684        Can be overridden by the `GIT_AUTHOR_EMAIL`, `GIT_COMMITTER_EMAIL`, and
3685        `EMAIL` environment variables.  See linkgit:git-commit-tree[1].
3686
3687user.name::
3688        Your full name to be recorded in any newly created commits.
3689        Can be overridden by the `GIT_AUTHOR_NAME` and `GIT_COMMITTER_NAME`
3690        environment variables.  See linkgit:git-commit-tree[1].
3691
3692user.useConfigOnly::
3693        Instruct Git to avoid trying to guess defaults for `user.email`
3694        and `user.name`, and instead retrieve the values only from the
3695        configuration. For example, if you have multiple email addresses
3696        and would like to use a different one for each repository, then
3697        with this configuration option set to `true` in the global config
3698        along with a name, Git will prompt you to set up an email before
3699        making new commits in a newly cloned repository.
3700        Defaults to `false`.
3701
3702user.signingKey::
3703        If linkgit:git-tag[1] or linkgit:git-commit[1] is not selecting the
3704        key you want it to automatically when creating a signed tag or
3705        commit, you can override the default selection with this variable.
3706        This option is passed unchanged to gpg's --local-user parameter,
3707        so you may specify a key using any method that gpg supports.
3708
3709versionsort.prereleaseSuffix (deprecated)::
3710        Deprecated alias for `versionsort.suffix`.  Ignored if
3711        `versionsort.suffix` is set.
3712
3713versionsort.suffix::
3714        Even when version sort is used in linkgit:git-tag[1], tagnames
3715        with the same base version but different suffixes are still sorted
3716        lexicographically, resulting e.g. in prerelease tags appearing
3717        after the main release (e.g. "1.0-rc1" after "1.0").  This
3718        variable can be specified to determine the sorting order of tags
3719        with different suffixes.
3720+
3721By specifying a single suffix in this variable, any tagname containing
3722that suffix will appear before the corresponding main release.  E.g. if
3723the variable is set to "-rc", then all "1.0-rcX" tags will appear before
3724"1.0".  If specified multiple times, once per suffix, then the order of
3725suffixes in the configuration will determine the sorting order of tagnames
3726with those suffixes.  E.g. if "-pre" appears before "-rc" in the
3727configuration, then all "1.0-preX" tags will be listed before any
3728"1.0-rcX" tags.  The placement of the main release tag relative to tags
3729with various suffixes can be determined by specifying the empty suffix
3730among those other suffixes.  E.g. if the suffixes "-rc", "", "-ck" and
3731"-bfs" appear in the configuration in this order, then all "v4.8-rcX" tags
3732are listed first, followed by "v4.8", then "v4.8-ckX" and finally
3733"v4.8-bfsX".
3734+
3735If more than one suffixes match the same tagname, then that tagname will
3736be sorted according to the suffix which starts at the earliest position in
3737the tagname.  If more than one different matching suffixes start at
3738that earliest position, then that tagname will be sorted according to the
3739longest of those suffixes.
3740The sorting order between different suffixes is undefined if they are
3741in multiple config files.
3742
3743web.browser::
3744        Specify a web browser that may be used by some commands.
3745        Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
3746        may use it.
3747
3748worktree.guessRemote::
3749        With `add`, if no branch argument, and neither of `-b` nor
3750        `-B` nor `--detach` are given, the command defaults to
3751        creating a new branch from HEAD.  If `worktree.guessRemote` is
3752        set to true, `worktree add` tries to find a remote-tracking
3753        branch whose name uniquely matches the new branch name.  If
3754        such a branch exists, it is checked out and set as "upstream"
3755        for the new branch.  If no such match can be found, it falls
3756        back to creating a new branch from the current HEAD.
