   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.

 206                path = foo.inc
 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 a value to its canonical form using the `--type=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.alternateRefsCommand::
 620        When advertising tips of available history from an alternate, use the shell to
 621        execute the specified command instead of linkgit:git-for-each-ref[1]. The
 622        first argument is the absolute path of the alternate. Output must contain one
 623        hex object id per line (i.e., the same as produced by `git for-each-ref
 624        --format='%(objectname)'`).
 625+
 626Note that you cannot generally put `git for-each-ref` directly into the config
 627value, as it does not take a repository path as an argument (but you can wrap
 628the command above in a shell script).
 629
 630core.alternateRefsPrefixes::
 631        When listing references from an alternate, list only references that begin
 632        with the given prefix. Prefixes match as if they were given as arguments to
 633        linkgit:git-for-each-ref[1]. To list multiple prefixes, separate them with
 634        whitespace. If `core.alternateRefsCommand` is set, setting
 635        `core.alternateRefsPrefixes` has no effect.
 636
 637core.bare::
 638        If true this repository is assumed to be 'bare' and has no
 639        working directory associated with it.  If this is the case a
 640        number of commands that require a working directory will be
 641        disabled, such as linkgit:git-add[1] or linkgit:git-merge[1].
 642+
 643This setting is automatically guessed by linkgit:git-clone[1] or
 644linkgit:git-init[1] when the repository was created.  By default a
 645repository that ends in "/.git" is assumed to be not bare (bare =
 646false), while all other repositories are assumed to be bare (bare
 647= true).
 648
 649core.worktree::
 650        Set the path to the root of the working tree.
 651        If `GIT_COMMON_DIR` environment variable is set, core.worktree
 652        is ignored and not used for determining the root of working tree.
 653        This can be overridden by the `GIT_WORK_TREE` environment
 654        variable and the `--work-tree` command-line option.
 655        The value can be an absolute path or relative to the path to
 656        the .git directory, which is either specified by --git-dir
 657        or GIT_DIR, or automatically discovered.
 658        If --git-dir or GIT_DIR is specified but none of
 659        --work-tree, GIT_WORK_TREE and core.worktree is specified,
 660        the current working directory is regarded as the top level
 661        of your working tree.
 662+
 663Note that this variable is honored even when set in a configuration
 664file in a ".git" subdirectory of a directory and its value differs
 665from the latter directory (e.g. "/path/to/.git/config" has
 666core.worktree set to "/different/path"), which is most likely a
 667misconfiguration.  Running Git commands in the "/path/to" directory will
 668still use "/different/path" as the root of the work tree and can cause
 669confusion unless you know what you are doing (e.g. you are creating a
 670read-only snapshot of the same index to a location different from the
 671repository's usual working tree).
 672
 673core.logAllRefUpdates::
 674        Enable the reflog. Updates to a ref <ref> is logged to the file
 675        "`$GIT_DIR/logs/<ref>`", by appending the new and old
 676        SHA-1, the date/time and the reason of the update, but
 677        only when the file exists.  If this configuration
 678        variable is set to `true`, missing "`$GIT_DIR/logs/<ref>`"
 679        file is automatically created for branch heads (i.e. under
 680        `refs/heads/`), remote refs (i.e. under `refs/remotes/`),
 681        note refs (i.e. under `refs/notes/`), and the symbolic ref `HEAD`.
 682        If it is set to `always`, then a missing reflog is automatically
 683        created for any ref under `refs/`.
 684+
 685This information can be used to determine what commit
 686was the tip of a branch "2 days ago".
 687+
 688This value is true by default in a repository that has
 689a working directory associated with it, and false by
 690default in a bare repository.
 691
 692core.repositoryFormatVersion::
 693        Internal variable identifying the repository format and layout
 694        version.
 695
 696core.sharedRepository::
 697        When 'group' (or 'true'), the repository is made shareable between
 698        several users in a group (making sure all the files and objects are
 699        group-writable). When 'all' (or 'world' or 'everybody'), the
 700        repository will be readable by all users, additionally to being
 701        group-shareable. When 'umask' (or 'false'), Git will use permissions
 702        reported by umask(2). When '0xxx', where '0xxx' is an octal number,
 703        files in the repository will have this mode value. '0xxx' will override
 704        user's umask value (whereas the other options will only override
 705        requested parts of the user's umask value). Examples: '0660' will make
 706        the repo read/write-able for the owner and group, but inaccessible to
 707        others (equivalent to 'group' unless umask is e.g. '0022'). '0640' is a
 708        repository that is group-readable but not group-writable.
 709        See linkgit:git-init[1]. False by default.
 710
 711core.warnAmbiguousRefs::
 712        If true, Git will warn you if the ref name you passed it is ambiguous
 713        and might match multiple refs in the repository. True by default.
 714
 715core.compression::
 716        An integer -1..9, indicating a default compression level.
 717        -1 is the zlib default. 0 means no compression,
 718        and 1..9 are various speed/size tradeoffs, 9 being slowest.
 719        If set, this provides a default to other compression variables,
 720        such as `core.looseCompression` and `pack.compression`.
 721
 722core.looseCompression::
 723        An integer -1..9, indicating the compression level for objects that
 724        are not in a pack file. -1 is the zlib default. 0 means no
 725        compression, and 1..9 are various speed/size tradeoffs, 9 being
 726        slowest.  If not set,  defaults to core.compression.  If that is
 727        not set,  defaults to 1 (best speed).
 728
 729core.packedGitWindowSize::
 730        Number of bytes of a pack file to map into memory in a
 731        single mapping operation.  Larger window sizes may allow
 732        your system to process a smaller number of large pack files
 733        more quickly.  Smaller window sizes will negatively affect
 734        performance due to increased calls to the operating system's
 735        memory manager, but may improve performance when accessing
 736        a large number of large pack files.
 737+
 738Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
 739MiB on 32 bit platforms and 1 GiB on 64 bit platforms.  This should
 740be reasonable for all users/operating systems.  You probably do
 741not need to adjust this value.
 742+
 743Common unit suffixes of 'k', 'm', or 'g' are supported.
 744
 745core.packedGitLimit::
 746        Maximum number of bytes to map simultaneously into memory
 747        from pack files.  If Git needs to access more than this many
 748        bytes at once to complete an operation it will unmap existing
 749        regions to reclaim virtual address space within the process.
 750+
 751Default is 256 MiB on 32 bit platforms and 32 TiB (effectively
 752unlimited) on 64 bit platforms.
 753This should be reasonable for all users/operating systems, except on
 754the largest projects.  You probably do not need to adjust this value.
 755+
 756Common unit suffixes of 'k', 'm', or 'g' are supported.
 757
 758core.deltaBaseCacheLimit::
 759        Maximum number of bytes to reserve for caching base objects
 760        that may be referenced by multiple deltified objects.  By storing the
 761        entire decompressed base objects in a cache Git is able
 762        to avoid unpacking and decompressing frequently used base
 763        objects multiple times.
 764+
 765Default is 96 MiB on all platforms.  This should be reasonable
 766for all users/operating systems, except on the largest projects.
 767You probably do not need to adjust this value.
 768+
 769Common unit suffixes of 'k', 'm', or 'g' are supported.
 770
 771core.bigFileThreshold::
 772        Files larger than this size are stored deflated, without
 773        attempting delta compression.  Storing large files without
 774        delta compression avoids excessive memory usage, at the
 775        slight expense of increased disk usage. Additionally files
 776        larger than this size are always treated as binary.
 777+
 778Default is 512 MiB on all platforms.  This should be reasonable
 779for most projects as source code and other text files can still
 780be delta compressed, but larger binary media files won't be.
 781+
 782Common unit suffixes of 'k', 'm', or 'g' are supported.
 783
 784core.excludesFile::
 785        Specifies the pathname to the file that contains patterns to
 786        describe paths that are not meant to be tracked, in addition
 787        to '.gitignore' (per-directory) and '.git/info/exclude'.
 788        Defaults to `$XDG_CONFIG_HOME/git/ignore`.
 789        If `$XDG_CONFIG_HOME` is either not set or empty, `$HOME/.config/git/ignore`
 790        is used instead. See linkgit:gitignore[5].
 791
 792core.askPass::
 793        Some commands (e.g. svn and http interfaces) that interactively
 794        ask for a password can be told to use an external program given
 795        via the value of this variable. Can be overridden by the `GIT_ASKPASS`
 796        environment variable. If not set, fall back to the value of the
 797        `SSH_ASKPASS` environment variable or, failing that, a simple password
 798        prompt. The external program shall be given a suitable prompt as
 799        command-line argument and write the password on its STDOUT.
 800
 801core.attributesFile::
 802        In addition to '.gitattributes' (per-directory) and
 803        '.git/info/attributes', Git looks into this file for attributes
 804        (see linkgit:gitattributes[5]). Path expansions are made the same
 805        way as for `core.excludesFile`. Its default value is
 806        `$XDG_CONFIG_HOME/git/attributes`. If `$XDG_CONFIG_HOME` is either not
 807        set or empty, `$HOME/.config/git/attributes` is used instead.
 808
 809core.hooksPath::
 810        By default Git will look for your hooks in the
 811        '$GIT_DIR/hooks' directory. Set this to different path,
 812        e.g. '/etc/git/hooks', and Git will try to find your hooks in
 813        that directory, e.g. '/etc/git/hooks/pre-receive' instead of
 814        in '$GIT_DIR/hooks/pre-receive'.
 815+
 816The path can be either absolute or relative. A relative path is
 817taken as relative to the directory where the hooks are run (see
 818the "DESCRIPTION" section of linkgit:githooks[5]).
 819+
 820This configuration variable is useful in cases where you'd like to
 821centrally configure your Git hooks instead of configuring them on a
 822per-repository basis, or as a more flexible and centralized
 823alternative to having an `init.templateDir` where you've changed
 824default hooks.
 825
 826core.editor::
 827        Commands such as `commit` and `tag` that let you edit
 828        messages by launching an editor use the value of this
 829        variable when it is set, and the environment variable
 830        `GIT_EDITOR` is not set.  See linkgit:git-var[1].
 831
 832core.commentChar::
 833        Commands such as `commit` and `tag` that let you edit
 834        messages consider a line that begins with this character
 835        commented, and removes them after the editor returns
 836        (default '#').
 837+
 838If set to "auto", `git-commit` would select a character that is not
 839the beginning character of any line in existing commit messages.
 840
 841core.filesRefLockTimeout::
 842        The length of time, in milliseconds, to retry when trying to
 843        lock an individual reference. Value 0 means not to retry at
 844        all; -1 means to try indefinitely. Default is 100 (i.e.,
 845        retry for 100ms).
 846
 847core.packedRefsTimeout::
 848        The length of time, in milliseconds, to retry when trying to
 849        lock the `packed-refs` file. Value 0 means not to retry at
 850        all; -1 means to try indefinitely. Default is 1000 (i.e.,
 851        retry for 1 second).
 852
 853core.pager::
 854        Text viewer for use by Git commands (e.g., 'less').  The value
 855        is meant to be interpreted by the shell.  The order of preference
 856        is the `$GIT_PAGER` environment variable, then `core.pager`
 857        configuration, then `$PAGER`, and then the default chosen at
 858        compile time (usually 'less').
 859+
 860When the `LESS` environment variable is unset, Git sets it to `FRX`
 861(if `LESS` environment variable is set, Git does not change it at
 862all).  If you want to selectively override Git's default setting
 863for `LESS`, you can set `core.pager` to e.g. `less -S`.  This will
 864be passed to the shell by Git, which will translate the final
 865command to `LESS=FRX less -S`. The environment does not set the
 866`S` option but the command line does, instructing less to truncate
 867long lines. Similarly, setting `core.pager` to `less -+F` will
 868deactivate the `F` option specified by the environment from the
 869command-line, deactivating the "quit if one screen" behavior of
 870`less`.  One can specifically activate some flags for particular
 871commands: for example, setting `pager.blame` to `less -S` enables
 872line truncation only for `git blame`.
 873+
 874Likewise, when the `LV` environment variable is unset, Git sets it
 875to `-c`.  You can override this setting by exporting `LV` with
 876another value or setting `core.pager` to `lv +c`.
 877
 878core.whitespace::
 879        A comma separated list of common whitespace problems to
 880        notice.  'git diff' will use `color.diff.whitespace` to
 881        highlight them, and 'git apply --whitespace=error' will
 882        consider them as errors.  You can prefix `-` to disable
 883        any of them (e.g. `-trailing-space`):
 884+
 885* `blank-at-eol` treats trailing whitespaces at the end of the line
 886  as an error (enabled by default).
 887* `space-before-tab` treats a space character that appears immediately
 888  before a tab character in the initial indent part of the line as an
 889  error (enabled by default).
 890* `indent-with-non-tab` treats a line that is indented with space
 891  characters instead of the equivalent tabs as an error (not enabled by
 892  default).
 893* `tab-in-indent` treats a tab character in the initial indent part of
 894  the line as an error (not enabled by default).
 895* `blank-at-eof` treats blank lines added at the end of file as an error
 896  (enabled by default).
 897* `trailing-space` is a short-hand to cover both `blank-at-eol` and
 898  `blank-at-eof`.
 899* `cr-at-eol` treats a carriage-return at the end of line as
 900  part of the line terminator, i.e. with it, `trailing-space`
 901  does not trigger if the character before such a carriage-return
 902  is not a whitespace (not enabled by default).
 903* `tabwidth=<n>` tells how many character positions a tab occupies; this
 904  is relevant for `indent-with-non-tab` and when Git fixes `tab-in-indent`
 905  errors. The default tab width is 8. Allowed values are 1 to 63.
 906
 907core.fsyncObjectFiles::
 908        This boolean will enable 'fsync()' when writing object files.
 909+
 910This is a total waste of time and effort on a filesystem that orders
 911data writes properly, but can be useful for filesystems that do not use
 912journalling (traditional UNIX filesystems) or that only journal metadata
 913and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback").
 914
 915core.preloadIndex::
 916        Enable parallel index preload for operations like 'git diff'
 917+
 918This can speed up operations like 'git diff' and 'git status' especially
 919on filesystems like NFS that have weak caching semantics and thus
 920relatively high IO latencies.  When enabled, Git will do the
 921index comparison to the filesystem data in parallel, allowing
 922overlapping IO's.  Defaults to true.
 923
 924core.createObject::
 925        You can set this to 'link', in which case a hardlink followed by
 926        a delete of the source are used to make sure that object creation
 927        will not overwrite existing objects.
 928+
 929On some file system/operating system combinations, this is unreliable.
 930Set this config setting to 'rename' there; However, This will remove the
 931check that makes sure that existing object files will not get overwritten.
 932
 933core.notesRef::
 934        When showing commit messages, also show notes which are stored in
 935        the given ref.  The ref must be fully qualified.  If the given
 936        ref does not exist, it is not an error but means that no
 937        notes should be printed.
 938+
 939This setting defaults to "refs/notes/commits", and it can be overridden by
 940the `GIT_NOTES_REF` environment variable.  See linkgit:git-notes[1].
 941
 942core.commitGraph::
 943        If true, then git will read the commit-graph file (if it exists)
 944        to parse the graph structure of commits. Defaults to false. See
 945        linkgit:git-commit-graph[1] for more information.
 946
 947core.useReplaceRefs::
 948        If set to `false`, behave as if the `--no-replace-objects`
 949        option was given on the command line. See linkgit:git[1] and
 950        linkgit:git-replace[1] for more information.
 951
 952core.multiPackIndex::
 953        Use the multi-pack-index file to track multiple packfiles using a
 954        single index. See link:technical/multi-pack-index.html[the
 955        multi-pack-index design document].
 956
 957core.sparseCheckout::
 958        Enable "sparse checkout" feature. See section "Sparse checkout" in
 959        linkgit:git-read-tree[1] for more information.
 960
 961core.abbrev::
 962        Set the length object names are abbreviated to.  If
 963        unspecified or set to "auto", an appropriate value is
 964        computed based on the approximate number of packed objects
 965        in your repository, which hopefully is enough for
 966        abbreviated object names to stay unique for some time.
 967        The minimum length is 4.
 968
 969add.ignoreErrors::
 970add.ignore-errors (deprecated)::
 971        Tells 'git add' to continue adding files when some files cannot be
 972        added due to indexing errors. Equivalent to the `--ignore-errors`
 973        option of linkgit:git-add[1].  `add.ignore-errors` is deprecated,
 974        as it does not follow the usual naming convention for configuration
 975        variables.
 976
 977alias.*::
 978        Command aliases for the linkgit:git[1] command wrapper - e.g.
 979        after defining "alias.last = cat-file commit HEAD", the invocation
 980        "git last" is equivalent to "git cat-file commit HEAD". To avoid
 981        confusion and troubles with script usage, aliases that
 982        hide existing Git commands are ignored. Arguments are split by
 983        spaces, the usual shell quoting and escaping is supported.
 984        A quote pair or a backslash can be used to quote them.
 985+
 986If the alias expansion is prefixed with an exclamation point,
 987it will be treated as a shell command.  For example, defining
 988"alias.new = !gitk --all --not ORIG_HEAD", the invocation
 989"git new" is equivalent to running the shell command
 990"gitk --all --not ORIG_HEAD".  Note that shell commands will be
 991executed from the top-level directory of a repository, which may
 992not necessarily be the current directory.
 993`GIT_PREFIX` is set as returned by running 'git rev-parse --show-prefix'
 994from the original current directory. See linkgit:git-rev-parse[1].
 995
 996am.keepcr::
 997        If true, git-am will call git-mailsplit for patches in mbox format
 998        with parameter `--keep-cr`. In this case git-mailsplit will
 999        not remove `\r` from lines ending with `\r\n`. Can be overridden
1000        by giving `--no-keep-cr` from the command line.
1001        See linkgit:git-am[1], linkgit:git-mailsplit[1].
1002
1003am.threeWay::
1004        By default, `git am` will fail if the patch does not apply cleanly. When
1005        set to true, this setting tells `git am` to fall back on 3-way merge if
1006        the patch records the identity of blobs it is supposed to apply to and
1007        we have those blobs available locally (equivalent to giving the `--3way`
1008        option from the command line). Defaults to `false`.
1009        See linkgit:git-am[1].
1010
1011apply.ignoreWhitespace::
1012        When set to 'change', tells 'git apply' to ignore changes in
1013        whitespace, in the same way as the `--ignore-space-change`
1014        option.
1015        When set to one of: no, none, never, false tells 'git apply' to
1016        respect all whitespace differences.
1017        See linkgit:git-apply[1].
1018
1019apply.whitespace::
1020        Tells 'git apply' how to handle whitespaces, in the same way
1021        as the `--whitespace` option. See linkgit:git-apply[1].
1022
1023blame.blankBoundary::
1024        Show blank commit object name for boundary commits in
1025        linkgit:git-blame[1]. This option defaults to false.
1026
1027blame.coloring::
1028        This determines the coloring scheme to be applied to blame
1029        output. It can be 'repeatedLines', 'highlightRecent',
1030        or 'none' which is the default.
1031
1032blame.date::
1033        Specifies the format used to output dates in linkgit:git-blame[1].
1034        If unset the iso format is used. For supported values,
1035        see the discussion of the `--date` option at linkgit:git-log[1].
1036
1037blame.showEmail::
1038        Show the author email instead of author name in linkgit:git-blame[1].
1039        This option defaults to false.
1040
1041blame.showRoot::
1042        Do not treat root commits as boundaries in linkgit:git-blame[1].
1043        This option defaults to false.
1044
1045branch.autoSetupMerge::
1046        Tells 'git branch' and 'git checkout' to set up new branches
1047        so that linkgit:git-pull[1] will appropriately merge from the
1048        starting point branch. Note that even if this option is not set,
1049        this behavior can be chosen per-branch using the `--track`
1050        and `--no-track` options. The valid settings are: `false` -- no
1051        automatic setup is done; `true` -- automatic setup is done when the
1052        starting point is a remote-tracking branch; `always` --
1053        automatic setup is done when the starting point is either a
1054        local branch or remote-tracking
1055        branch. This option defaults to true.
1056
1057branch.autoSetupRebase::
1058        When a new branch is created with 'git branch' or 'git checkout'
1059        that tracks another branch, this variable tells Git to set
1060        up pull to rebase instead of merge (see "branch.<name>.rebase").
1061        When `never`, rebase is never automatically set to true.
1062        When `local`, rebase is set to true for tracked branches of
1063        other local branches.
1064        When `remote`, rebase is set to true for tracked branches of
1065        remote-tracking branches.
1066        When `always`, rebase will be set to true for all tracking
1067        branches.
1068        See "branch.autoSetupMerge" for details on how to set up a
1069        branch to track another branch.
1070        This option defaults to never.
1071
1072branch.sort::
1073        This variable controls the sort ordering of branches when displayed by
1074        linkgit:git-branch[1]. Without the "--sort=<value>" option provided, the
1075        value of this variable will be used as the default.
1076        See linkgit:git-for-each-ref[1] field names for valid values.
1077
1078branch.<name>.remote::
1079        When on branch <name>, it tells 'git fetch' and 'git push'
1080        which remote to fetch from/push to.  The remote to push to
1081        may be overridden with `remote.pushDefault` (for all branches).
1082        The remote to push to, for the current branch, may be further
1083        overridden by `branch.<name>.pushRemote`.  If no remote is
1084        configured, or if you are not on any branch, it defaults to
1085        `origin` for fetching and `remote.pushDefault` for pushing.
1086        Additionally, `.` (a period) is the current local repository
1087        (a dot-repository), see `branch.<name>.merge`'s final note below.
1088
1089branch.<name>.pushRemote::
1090        When on branch <name>, it overrides `branch.<name>.remote` for
1091        pushing.  It also overrides `remote.pushDefault` for pushing
1092        from branch <name>.  When you pull from one place (e.g. your
1093        upstream) and push to another place (e.g. your own publishing
1094        repository), you would want to set `remote.pushDefault` to
1095        specify the remote to push to for all branches, and use this
1096        option to override it for a specific branch.
1097
1098branch.<name>.merge::
1099        Defines, together with branch.<name>.remote, the upstream branch
1100        for the given branch. It tells 'git fetch'/'git pull'/'git rebase' which
1101        branch to merge and can also affect 'git push' (see push.default).
1102        When in branch <name>, it tells 'git fetch' the default
1103        refspec to be marked for merging in FETCH_HEAD. The value is
1104        handled like the remote part of a refspec, and must match a
1105        ref which is fetched from the remote given by
1106        "branch.<name>.remote".
1107        The merge information is used by 'git pull' (which at first calls
1108        'git fetch') to lookup the default branch for merging. Without
1109        this option, 'git pull' defaults to merge the first refspec fetched.
1110        Specify multiple values to get an octopus merge.
1111        If you wish to setup 'git pull' so that it merges into <name> from
1112        another branch in the local repository, you can point
1113        branch.<name>.merge to the desired branch, and use the relative path
1114        setting `.` (a period) for branch.<name>.remote.
1115
1116branch.<name>.mergeOptions::
1117        Sets default options for merging into branch <name>. The syntax and
1118        supported options are the same as those of linkgit:git-merge[1], but
1119        option values containing whitespace characters are currently not
1120        supported.
1121
1122branch.<name>.rebase::
1123        When true, rebase the branch <name> on top of the fetched branch,
1124        instead of merging the default branch from the default remote when
1125        "git pull" is run. See "pull.rebase" for doing this in a non
1126        branch-specific manner.
1127+
1128When `merges`, pass the `--rebase-merges` option to 'git rebase'
1129so that the local merge commits are included in the rebase (see
1130linkgit:git-rebase[1] for details).
1131+
1132When preserve, also pass `--preserve-merges` along to 'git rebase'
1133so that locally committed merge commits will not be flattened
1134by running 'git pull'.
1135+
1136When the value is `interactive`, the rebase is run in interactive mode.
1137+
1138*NOTE*: this is a possibly dangerous operation; do *not* use
1139it unless you understand the implications (see linkgit:git-rebase[1]
1140for details).
1141
1142branch.<name>.description::
1143        Branch description, can be edited with
1144        `git branch --edit-description`. Branch description is
1145        automatically added in the format-patch cover letter or
1146        request-pull summary.
1147
1148browser.<tool>.cmd::
1149        Specify the command to invoke the specified browser. The
1150        specified command is evaluated in shell with the URLs passed
1151        as arguments. (See linkgit:git-web{litdd}browse[1].)
1152
1153browser.<tool>.path::
1154        Override the path for the given tool that may be used to
1155        browse HTML help (see `-w` option in linkgit:git-help[1]) or a
1156        working repository in gitweb (see linkgit:git-instaweb[1]).
1157
1158checkout.defaultRemote::
1159        When you run 'git checkout <something>' and only have one
1160        remote, it may implicitly fall back on checking out and
1161        tracking e.g. 'origin/<something>'. This stops working as soon
1162        as you have more than one remote with a '<something>'
1163        reference. This setting allows for setting the name of a
1164        preferred remote that should always win when it comes to
1165        disambiguation. The typical use-case is to set this to
1166        `origin`.
1167+
1168Currently this is used by linkgit:git-checkout[1] when 'git checkout
1169<something>' will checkout the '<something>' branch on another remote,
1170and by linkgit:git-worktree[1] when 'git worktree add' refers to a
1171remote branch. This setting might be used for other checkout-like
1172commands or functionality in the future.
1173
1174checkout.optimizeNewBranch::
1175        Optimizes the performance of "git checkout -b <new_branch>" when
1176        using sparse-checkout.  When set to true, git will not update the
1177        repo based on the current sparse-checkout settings.  This means it
1178        will not update the skip-worktree bit in the index nor add/remove
1179        files in the working directory to reflect the current sparse checkout
1180        settings nor will it show the local changes.
1181
1182clean.requireForce::
1183        A boolean to make git-clean do nothing unless given -f,
1184        -i or -n.   Defaults to true.
1185
1186color.advice::
1187        A boolean to enable/disable color in hints (e.g. when a push
1188        failed, see `advice.*` for a list).  May be set to `always`,
1189        `false` (or `never`) or `auto` (or `true`), in which case colors
1190        are used only when the error output goes to a terminal. If
1191        unset, then the value of `color.ui` is used (`auto` by default).
1192
1193color.advice.hint::
1194        Use customized color for hints.
1195
1196color.blame.highlightRecent::
1197        This can be used to color the metadata of a blame line depending
1198        on age of the line.
1199+
1200This setting should be set to a comma-separated list of color and date settings,
1201starting and ending with a color, the dates should be set from oldest to newest.
1202The metadata will be colored given the colors if the the line was introduced
1203before the given timestamp, overwriting older timestamped colors.
1204+
1205Instead of an absolute timestamp relative timestamps work as well, e.g.
12062.weeks.ago is valid to address anything older than 2 weeks.
1207+
1208It defaults to 'blue,12 month ago,white,1 month ago,red', which colors
1209everything older than one year blue, recent changes between one month and
1210one year old are kept white, and lines introduced within the last month are
1211colored red.
1212
1213color.blame.repeatedLines::
1214        Use the customized color for the part of git-blame output that
1215        is repeated meta information per line (such as commit id,
1216        author name, date and timezone). Defaults to cyan.
1217
1218color.branch::
1219        A boolean to enable/disable color in the output of
1220        linkgit:git-branch[1]. May be set to `always`,
1221        `false` (or `never`) or `auto` (or `true`), in which case colors are used
1222        only when the output is to a terminal. If unset, then the
1223        value of `color.ui` is used (`auto` by default).
1224
1225color.branch.<slot>::
1226        Use customized color for branch coloration. `<slot>` is one of
1227        `current` (the current branch), `local` (a local branch),
1228        `remote` (a remote-tracking branch in refs/remotes/),
1229        `upstream` (upstream tracking branch), `plain` (other
1230        refs).
1231
1232color.diff::
1233        Whether to use ANSI escape sequences to add color to patches.
1234        If this is set to `always`, linkgit:git-diff[1],
1235        linkgit:git-log[1], and linkgit:git-show[1] will use color
1236        for all patches.  If it is set to `true` or `auto`, those
1237        commands will only use color when output is to the terminal.
1238        If unset, then the value of `color.ui` is used (`auto` by
1239        default).
1240+
1241This does not affect linkgit:git-format-patch[1] or the
1242'git-diff-{asterisk}' plumbing commands.  Can be overridden on the
1243command line with the `--color[=<when>]` option.
1244
1245color.diff.<slot>::
1246        Use customized color for diff colorization.  `<slot>` specifies
1247        which part of the patch to use the specified color, and is one
1248        of `context` (context text - `plain` is a historical synonym),
1249        `meta` (metainformation), `frag`
1250        (hunk header), 'func' (function in hunk header), `old` (removed lines),
1251        `new` (added lines), `commit` (commit headers), `whitespace`
1252        (highlighting whitespace errors), `oldMoved` (deleted lines),
1253        `newMoved` (added lines), `oldMovedDimmed`, `oldMovedAlternative`,
1254        `oldMovedAlternativeDimmed`, `newMovedDimmed`, `newMovedAlternative`
1255        `newMovedAlternativeDimmed` (See the '<mode>'
1256        setting of '--color-moved' in linkgit:git-diff[1] for details),
1257        `contextDimmed`, `oldDimmed`, `newDimmed`, `contextBold`,
1258        `oldBold`, and `newBold` (see linkgit:git-range-diff[1] for details).
1259
1260color.decorate.<slot>::
1261        Use customized color for 'git log --decorate' output.  `<slot>` is one
1262        of `branch`, `remoteBranch`, `tag`, `stash` or `HEAD` for local
1263        branches, remote-tracking branches, tags, stash and HEAD, respectively
1264        and `grafted` for grafted commits.
1265
1266color.grep::
1267        When set to `always`, always highlight matches.  When `false` (or
1268        `never`), never.  When set to `true` or `auto`, use color only
1269        when the output is written to the terminal.  If unset, then the
1270        value of `color.ui` is used (`auto` by default).
1271
1272color.grep.<slot>::
1273        Use customized color for grep colorization.  `<slot>` specifies which
1274        part of the line to use the specified color, and is one of
1275+
1276--
1277`context`;;
1278        non-matching text in context lines (when using `-A`, `-B`, or `-C`)
1279`filename`;;
1280        filename prefix (when not using `-h`)
1281`function`;;
1282        function name lines (when using `-p`)
1283`lineNumber`;;
1284        line number prefix (when using `-n`)
1285`column`;;
1286        column number prefix (when using `--column`)
1287`match`;;
1288        matching text (same as setting `matchContext` and `matchSelected`)
1289`matchContext`;;
1290        matching text in context lines
1291`matchSelected`;;
1292        matching text in selected lines
1293`selected`;;
1294        non-matching text in selected lines
1295`separator`;;
1296        separators between fields on a line (`:`, `-`, and `=`)
1297        and between hunks (`--`)
1298--
1299
1300color.interactive::
1301        When set to `always`, always use colors for interactive prompts
1302        and displays (such as those used by "git-add --interactive" and
1303        "git-clean --interactive"). When false (or `never`), never.
1304        When set to `true` or `auto`, use colors only when the output is
1305        to the terminal. If unset, then the value of `color.ui` is
1306        used (`auto` by default).
1307
1308color.interactive.<slot>::
1309        Use customized color for 'git add --interactive' and 'git clean
1310        --interactive' output. `<slot>` may be `prompt`, `header`, `help`
1311        or `error`, for four distinct types of normal output from
1312        interactive commands.
1313
1314color.pager::
1315        A boolean to enable/disable colored output when the pager is in
1316        use (default is true).
1317
1318color.push::
1319        A boolean to enable/disable color in push errors. May be set to
1320        `always`, `false` (or `never`) or `auto` (or `true`), in which
1321        case colors are used only when the error output goes to a terminal.
1322        If unset, then the value of `color.ui` is used (`auto` by default).
1323
1324color.push.error::
1325        Use customized color for push errors.
1326
1327color.remote::
1328        If set, keywords at the start of the line are highlighted. The
1329        keywords are "error", "warning", "hint" and "success", and are
1330        matched case-insensitively. May be set to `always`, `false` (or
1331        `never`) or `auto` (or `true`). If unset, then the value of
1332        `color.ui` is used (`auto` by default).
1333
1334color.remote.<slot>::
1335        Use customized color for each remote keyword. `<slot>` may be
1336        `hint`, `warning`, `success` or `error` which match the
1337        corresponding keyword.
1338
1339color.showBranch::
1340        A boolean to enable/disable color in the output of
1341        linkgit:git-show-branch[1]. May be set to `always`,
1342        `false` (or `never`) or `auto` (or `true`), in which case colors are used
1343        only when the output is to a terminal. If unset, then the
1344        value of `color.ui` is used (`auto` by default).
1345
1346color.status::
1347        A boolean to enable/disable color in the output of
1348        linkgit:git-status[1]. May be set to `always`,
1349        `false` (or `never`) or `auto` (or `true`), in which case colors are used
1350        only when the output is to a terminal. If unset, then the
1351        value of `color.ui` is used (`auto` by default).
1352
1353color.status.<slot>::
1354        Use customized color for status colorization. `<slot>` is
1355        one of `header` (the header text of the status message),
1356        `added` or `updated` (files which are added but not committed),
1357        `changed` (files which are changed but not added in the index),
1358        `untracked` (files which are not tracked by Git),
1359        `branch` (the current branch),
1360        `nobranch` (the color the 'no branch' warning is shown in, defaulting
1361        to red),
1362        `localBranch` or `remoteBranch` (the local and remote branch names,
1363        respectively, when branch and tracking information is displayed in the
1364        status short-format), or
1365        `unmerged` (files which have unmerged changes).
1366
1367color.transport::
1368        A boolean to enable/disable color when pushes are rejected. May be
1369        set to `always`, `false` (or `never`) or `auto` (or `true`), in which
1370        case colors are used only when the error output goes to a terminal.
1371        If unset, then the value of `color.ui` is used (`auto` by default).
1372
1373color.transport.rejected::
1374        Use customized color when a push was rejected.
1375
1376color.ui::
1377        This variable determines the default value for variables such
1378        as `color.diff` and `color.grep` that control the use of color
1379        per command family. Its scope will expand as more commands learn
1380        configuration to set a default for the `--color` option.  Set it
1381        to `false` or `never` if you prefer Git commands not to use
1382        color unless enabled explicitly with some other configuration
1383        or the `--color` option. Set it to `always` if you want all
1384        output not intended for machine consumption to use color, to
1385        `true` or `auto` (this is the default since Git 1.8.4) if you
1386        want such output to use color when written to the terminal.
1387
1388column.ui::
1389        Specify whether supported commands should output in columns.
1390        This variable consists of a list of tokens separated by spaces
1391        or commas:
1392+
1393These options control when the feature should be enabled
1394(defaults to 'never'):
1395+
1396--
1397`always`;;
1398        always show in columns
1399`never`;;
1400        never show in columns
1401`auto`;;
1402        show in columns if the output is to the terminal
1403--
1404+
1405These options control layout (defaults to 'column').  Setting any
1406of these implies 'always' if none of 'always', 'never', or 'auto' are
1407specified.
1408+
1409--
1410`column`;;
1411        fill columns before rows
1412`row`;;
1413        fill rows before columns
1414`plain`;;
1415        show in one column
1416--
1417+
1418Finally, these options can be combined with a layout option (defaults
1419to 'nodense'):
1420+
1421--
1422`dense`;;
1423        make unequal size columns to utilize more space
1424`nodense`;;
1425        make equal size columns
1426--
1427
1428column.branch::
1429        Specify whether to output branch listing in `git branch` in columns.
1430        See `column.ui` for details.
1431
1432column.clean::
1433        Specify the layout when list items in `git clean -i`, which always
1434        shows files and directories in columns. See `column.ui` for details.
1435
1436column.status::
1437        Specify whether to output untracked files in `git status` in columns.
1438        See `column.ui` for details.
1439
1440column.tag::
1441        Specify whether to output tag listing in `git tag` in columns.
1442        See `column.ui` for details.
1443
1444commit.cleanup::
1445        This setting overrides the default of the `--cleanup` option in
1446        `git commit`. See linkgit:git-commit[1] for details. Changing the
1447        default can be useful when you always want to keep lines that begin
1448        with comment character `#` in your log message, in which case you
1449        would do `git config commit.cleanup whitespace` (note that you will
1450        have to remove the help lines that begin with `#` in the commit log
1451        template yourself, if you do this).
1452
1453commit.gpgSign::
1454
1455        A boolean to specify whether all commits should be GPG signed.
1456        Use of this option when doing operations such as rebase can
1457        result in a large number of commits being signed. It may be
1458        convenient to use an agent to avoid typing your GPG passphrase
1459        several times.
1460
1461commit.status::
1462        A boolean to enable/disable inclusion of status information in the
1463        commit message template when using an editor to prepare the commit
1464        message.  Defaults to true.
1465
1466commit.template::
1467        Specify the pathname of a file to use as the template for
1468        new commit messages.
1469
1470commit.verbose::
1471        A boolean or int to specify the level of verbose with `git commit`.
1472        See linkgit:git-commit[1].
1473
1474credential.helper::
1475        Specify an external helper to be called when a username or
1476        password credential is needed; the helper may consult external
1477        storage to avoid prompting the user for the credentials. Note
1478        that multiple helpers may be defined. See linkgit:gitcredentials[7]
1479        for details.
1480
1481credential.useHttpPath::
1482        When acquiring credentials, consider the "path" component of an http
1483        or https URL to be important. Defaults to false. See
1484        linkgit:gitcredentials[7] for more information.
1485
1486credential.username::
1487        If no username is set for a network authentication, use this username
1488        by default. See credential.<context>.* below, and
1489        linkgit:gitcredentials[7].
1490
1491credential.<url>.*::
1492        Any of the credential.* options above can be applied selectively to
1493        some credentials. For example "credential.https://example.com.username"
1494        would set the default username only for https connections to
1495        example.com. See linkgit:gitcredentials[7] for details on how URLs are
1496        matched.
1497
1498credentialCache.ignoreSIGHUP::
1499        Tell git-credential-cache--daemon to ignore SIGHUP, instead of quitting.
1500
1501completion.commands::
1502        This is only used by git-completion.bash to add or remove
1503        commands from the list of completed commands. Normally only
1504        porcelain commands and a few select others are completed. You
1505        can add more commands, separated by space, in this
1506        variable. Prefixing the command with '-' will remove it from
1507        the existing list.
1508
1509include::diff-config.txt[]
1510
1511difftool.<tool>.path::
1512        Override the path for the given tool.  This is useful in case
1513        your tool is not in the PATH.
1514
1515difftool.<tool>.cmd::
1516        Specify the command to invoke the specified diff tool.
1517        The specified command is evaluated in shell with the following
1518        variables available:  'LOCAL' is set to the name of the temporary
1519        file containing the contents of the diff pre-image and 'REMOTE'
1520        is set to the name of the temporary file containing the contents
1521        of the diff post-image.
1522
1523difftool.prompt::
1524        Prompt before each invocation of the diff tool.
1525
1526fastimport.unpackLimit::
1527        If the number of objects imported by linkgit:git-fast-import[1]
1528        is below this limit, then the objects will be unpacked into
1529        loose object files.  However if the number of imported objects
1530        equals or exceeds this limit then the pack will be stored as a
1531        pack.  Storing the pack from a fast-import can make the import
1532        operation complete faster, especially on slow filesystems.  If
1533        not set, the value of `transfer.unpackLimit` is used instead.
1534
1535include::fetch-config.txt[]
1536
1537include::format-config.txt[]
1538
1539filter.<driver>.clean::
1540        The command which is used to convert the content of a worktree
1541        file to a blob upon checkin.  See linkgit:gitattributes[5] for
1542        details.
1543
1544filter.<driver>.smudge::
1545        The command which is used to convert the content of a blob
1546        object to a worktree file upon checkout.  See
1547        linkgit:gitattributes[5] for details.
1548
1549fsck.<msg-id>::
1550        During fsck git may find issues with legacy data which
1551        wouldn't be generated by current versions of git, and which
1552        wouldn't be sent over the wire if `transfer.fsckObjects` was
1553        set. This feature is intended to support working with legacy
1554        repositories containing such data.
1555+
1556Setting `fsck.<msg-id>` will be picked up by linkgit:git-fsck[1], but
1557to accept pushes of such data set `receive.fsck.<msg-id>` instead, or
1558to clone or fetch it set `fetch.fsck.<msg-id>`.
1559+
1560The rest of the documentation discusses `fsck.*` for brevity, but the
1561same applies for the corresponding `receive.fsck.*` and
1562`fetch.<msg-id>.*`. variables.
1563+
1564Unlike variables like `color.ui` and `core.editor` the
1565`receive.fsck.<msg-id>` and `fetch.fsck.<msg-id>` variables will not
1566fall back on the `fsck.<msg-id>` configuration if they aren't set. To
1567uniformly configure the same fsck settings in different circumstances
1568all three of them they must all set to the same values.
1569+
1570When `fsck.<msg-id>` is set, errors can be switched to warnings and
1571vice versa by configuring the `fsck.<msg-id>` setting where the
1572`<msg-id>` is the fsck message ID and the value is one of `error`,
1573`warn` or `ignore`. For convenience, fsck prefixes the error/warning
1574with the message ID, e.g. "missingEmail: invalid author/committer line
1575- missing email" means that setting `fsck.missingEmail = ignore` will
1576hide that issue.
1577+
1578In general, it is better to enumerate existing objects with problems
1579with `fsck.skipList`, instead of listing the kind of breakages these
1580problematic objects share to be ignored, as doing the latter will
1581allow new instances of the same breakages go unnoticed.
1582+
1583Setting an unknown `fsck.<msg-id>` value will cause fsck to die, but
1584doing the same for `receive.fsck.<msg-id>` and `fetch.fsck.<msg-id>`
1585will only cause git to warn.
1586
1587fsck.skipList::
1588        The path to a list of object names (i.e. one unabbreviated SHA-1 per
1589        line) that are known to be broken in a non-fatal way and should
1590        be ignored. On versions of Git 2.20 and later comments ('#'), empty
1591        lines, and any leading and trailing whitespace is ignored. Everything
1592        but a SHA-1 per line will error out on older versions.
1593+
1594This feature is useful when an established project should be accepted
1595despite early commits containing errors that can be safely ignored
1596such as invalid committer email addresses.  Note: corrupt objects
1597cannot be skipped with this setting.
1598+
1599Like `fsck.<msg-id>` this variable has corresponding
1600`receive.fsck.skipList` and `fetch.fsck.skipList` variants.
1601+
1602Unlike variables like `color.ui` and `core.editor` the
1603`receive.fsck.skipList` and `fetch.fsck.skipList` variables will not
1604fall back on the `fsck.skipList` configuration if they aren't set. To
1605uniformly configure the same fsck settings in different circumstances
1606all three of them they must all set to the same values.
1607+
1608Older versions of Git (before 2.20) documented that the object names
1609list should be sorted. This was never a requirement, the object names
1610could appear in any order, but when reading the list we tracked whether
1611the list was sorted for the purposes of an internal binary search
1612implementation, which could save itself some work with an already sorted
1613list. Unless you had a humongous list there was no reason to go out of
1614your way to pre-sort the list. After Git version 2.20 a hash implementation
1615is used instead, so there's now no reason to pre-sort the list.
1616
1617gc.aggressiveDepth::
1618        The depth parameter used in the delta compression
1619        algorithm used by 'git gc --aggressive'.  This defaults
1620        to 50.
1621
1622gc.aggressiveWindow::
1623        The window size parameter used in the delta compression
1624        algorithm used by 'git gc --aggressive'.  This defaults
1625        to 250.
1626
1627gc.auto::
1628        When there are approximately more than this many loose
1629        objects in the repository, `git gc --auto` will pack them.
1630        Some Porcelain commands use this command to perform a
1631        light-weight garbage collection from time to time.  The
1632        default value is 6700.  Setting this to 0 disables it.
1633
1634gc.autoPackLimit::
1635        When there are more than this many packs that are not
1636        marked with `*.keep` file in the repository, `git gc
1637        --auto` consolidates them into one larger pack.  The
1638        default value is 50.  Setting this to 0 disables it.
1639
1640gc.autoDetach::
1641        Make `git gc --auto` return immediately and run in background
1642        if the system supports it. Default is true.
1643
1644gc.bigPackThreshold::
1645        If non-zero, all packs larger than this limit are kept when
1646        `git gc` is run. This is very similar to `--keep-base-pack`
1647        except that all packs that meet the threshold are kept, not
1648        just the base pack. Defaults to zero. Common unit suffixes of
1649        'k', 'm', or 'g' are supported.
1650+
1651Note that if the number of kept packs is more than gc.autoPackLimit,
1652this configuration variable is ignored, all packs except the base pack
1653will be repacked. After this the number of packs should go below
1654gc.autoPackLimit and gc.bigPackThreshold should be respected again.
1655
1656gc.writeCommitGraph::
1657        If true, then gc will rewrite the commit-graph file when
1658        linkgit:git-gc[1] is run. When using linkgit:git-gc[1]
1659        '--auto' the commit-graph will be updated if housekeeping is
1660        required. Default is false. See linkgit:git-commit-graph[1]
1661        for details.
1662
1663gc.logExpiry::
1664        If the file gc.log exists, then `git gc --auto` will print
1665        its content and exit with status zero instead of running
1666        unless that file is more than 'gc.logExpiry' old.  Default is
1667        "1.day".  See `gc.pruneExpire` for more ways to specify its
1668        value.
1669
1670gc.packRefs::
1671        Running `git pack-refs` in a repository renders it
1672        unclonable by Git versions prior to 1.5.1.2 over dumb
1673        transports such as HTTP.  This variable determines whether
1674        'git gc' runs `git pack-refs`. This can be set to `notbare`
1675        to enable it within all non-bare repos or it can be set to a
1676        boolean value.  The default is `true`.
1677
1678gc.pruneExpire::
1679        When 'git gc' is run, it will call 'prune --expire 2.weeks.ago'.
1680        Override the grace period with this config variable.  The value
1681        "now" may be used to disable this grace period and always prune
1682        unreachable objects immediately, or "never" may be used to
1683        suppress pruning.  This feature helps prevent corruption when
1684        'git gc' runs concurrently with another process writing to the
1685        repository; see the "NOTES" section of linkgit:git-gc[1].
1686
1687gc.worktreePruneExpire::
1688        When 'git gc' is run, it calls
1689        'git worktree prune --expire 3.months.ago'.
1690        This config variable can be used to set a different grace
1691        period. The value "now" may be used to disable the grace
1692        period and prune `$GIT_DIR/worktrees` immediately, or "never"
1693        may be used to suppress pruning.
1694
1695gc.reflogExpire::
1696gc.<pattern>.reflogExpire::
1697        'git reflog expire' removes reflog entries older than
1698        this time; defaults to 90 days. The value "now" expires all
1699        entries immediately, and "never" suppresses expiration
1700        altogether. With "<pattern>" (e.g.
1701        "refs/stash") in the middle the setting applies only to
1702        the refs that match the <pattern>.
1703
1704gc.reflogExpireUnreachable::
1705gc.<pattern>.reflogExpireUnreachable::
1706        'git reflog expire' removes reflog entries older than
1707        this time and are not reachable from the current tip;
1708        defaults to 30 days. The value "now" expires all entries
1709        immediately, and "never" suppresses expiration altogether.
1710        With "<pattern>" (e.g. "refs/stash")
1711        in the middle, the setting applies only to the refs that
1712        match the <pattern>.
1713
1714gc.rerereResolved::
1715        Records of conflicted merge you resolved earlier are
1716        kept for this many days when 'git rerere gc' is run.
1717        You can also use more human-readable "1.month.ago", etc.
1718        The default is 60 days.  See linkgit:git-rerere[1].
1719
1720gc.rerereUnresolved::
1721        Records of conflicted merge you have not resolved are
1722        kept for this many days when 'git rerere gc' is run.
1723        You can also use more human-readable "1.month.ago", etc.
1724        The default is 15 days.  See linkgit:git-rerere[1].

1745grep.lineNumber::
1746        If set to true, enable `-n` option by default.
1747
1748grep.column::
1749        If set to true, enable the `--column` option by default.
1750
1751grep.patternType::
1752        Set the default matching behavior. Using a value of 'basic', 'extended',
1753        'fixed', or 'perl' will enable the `--basic-regexp`, `--extended-regexp`,
1754        `--fixed-strings`, or `--perl-regexp` option accordingly, while the
1755        value 'default' will return to the default matching behavior.
1756
1757grep.extendedRegexp::
1758        If set to true, enable `--extended-regexp` option by default. This
1759        option is ignored when the `grep.patternType` option is set to a value
1760        other than 'default'.
1761
1762grep.threads::
1763        Number of grep worker threads to use.
1764        See `grep.threads` in linkgit:git-grep[1] for more information.
1765
1766grep.fallbackToNoIndex::
1767        If set to true, fall back to git grep --no-index if git grep
1768        is executed outside of a git repository.  Defaults to false.
1769
1770gpg.program::
1771        Use this custom program instead of "`gpg`" found on `$PATH` when
1772        making or verifying a PGP signature. The program must support the
1773        same command-line interface as GPG, namely, to verify a detached
1774        signature, "`gpg --verify $file - <$signature`" is run, and the
1775        program is expected to signal a good signature by exiting with
1776        code 0, and to generate an ASCII-armored detached signature, the
1777        standard input of "`gpg -bsau $key`" is fed with the contents to be
1778        signed, and the program is expected to send the result to its
1779        standard output.
1780
1781gpg.format::
1782        Specifies which key format to use when signing with `--gpg-sign`.
1783        Default is "openpgp" and another possible value is "x509".
1784
1785gpg.<format>.program::
1786        Use this to customize the program used for the signing format you
1787        chose. (see `gpg.program` and `gpg.format`) `gpg.program` can still
1788        be used as a legacy synonym for `gpg.openpgp.program`. The default
1789        value for `gpg.x509.program` is "gpgsm".
1790
1791include::gui-config.txt[]
1792
1793guitool.<name>.cmd::
1794        Specifies the shell command line to execute when the corresponding item
1795        of the linkgit:git-gui[1] `Tools` menu is invoked. This option is
1796        mandatory for every tool. The command is executed from the root of
1797        the working directory, and in the environment it receives the name of
1798        the tool as `GIT_GUITOOL`, the name of the currently selected file as
1799        'FILENAME', and the name of the current branch as 'CUR_BRANCH' (if
1800        the head is detached, 'CUR_BRANCH' is empty).
1801
1802guitool.<name>.needsFile::
1803        Run the tool only if a diff is selected in the GUI. It guarantees
1804        that 'FILENAME' is not empty.
1805
1806guitool.<name>.noConsole::
1807        Run the command silently, without creating a window to display its
1808        output.
1809
1810guitool.<name>.noRescan::
1811        Don't rescan the working directory for changes after the tool
1812        finishes execution.
1813
1814guitool.<name>.confirm::
1815        Show a confirmation dialog before actually running the tool.
1816
1817guitool.<name>.argPrompt::
1818        Request a string argument from the user, and pass it to the tool
1819        through the `ARGS` environment variable. Since requesting an
1820        argument implies confirmation, the 'confirm' option has no effect
1821        if this is enabled. If the option is set to 'true', 'yes', or '1',
1822        the dialog uses a built-in generic prompt; otherwise the exact
1823        value of the variable is used.
1824
1825guitool.<name>.revPrompt::
1826        Request a single valid revision from the user, and set the
1827        `REVISION` environment variable. In other aspects this option
1828        is similar to 'argPrompt', and can be used together with it.
1829
1830guitool.<name>.revUnmerged::
1831        Show only unmerged branches in the 'revPrompt' subdialog.
1832        This is useful for tools similar to merge or rebase, but not
1833        for things like checkout or reset.
1834
1835guitool.<name>.title::
1836        Specifies the title to use for the prompt dialog. The default
1837        is the tool name.
1838
1839guitool.<name>.prompt::
1840        Specifies the general prompt string to display at the top of
1841        the dialog, before subsections for 'argPrompt' and 'revPrompt'.
1842        The default value includes the actual command.
1843
1844help.browser::
1845        Specify the browser that will be used to display help in the
1846        'web' format. See linkgit:git-help[1].
1847
1848help.format::
1849        Override the default help format used by linkgit:git-help[1].
1850        Values 'man', 'info', 'web' and 'html' are supported. 'man' is
1851        the default. 'web' and 'html' are the same.
1852
1853help.autoCorrect::
1854        Automatically correct and execute mistyped commands after
1855        waiting for the given number of deciseconds (0.1 sec). If more
1856        than one command can be deduced from the entered text, nothing
1857        will be executed.  If the value of this option is negative,
1858        the corrected command will be executed immediately. If the
1859        value is 0 - the command will be just shown but not executed.
1860        This is the default.
1861
1862help.htmlPath::
1863        Specify the path where the HTML documentation resides. File system paths
1864        and URLs are supported. HTML pages will be prefixed with this path when
1865        help is displayed in the 'web' format. This defaults to the documentation
1866        path of your Git installation.
1867
1868http.proxy::
1869        Override the HTTP proxy, normally configured using the 'http_proxy',
1870        'https_proxy', and 'all_proxy' environment variables (see `curl(1)`). In
1871        addition to the syntax understood by curl, it is possible to specify a
1872        proxy string with a user name but no password, in which case git will
1873        attempt to acquire one in the same way it does for other credentials. See
1874        linkgit:gitcredentials[7] for more information. The syntax thus is
1875        '[protocol://][user[:password]@]proxyhost[:port]'. This can be overridden
1876        on a per-remote basis; see remote.<name>.proxy
1877
1878http.proxyAuthMethod::
1879        Set the method with which to authenticate against the HTTP proxy. This
1880        only takes effect if the configured proxy string contains a user name part
1881        (i.e. is of the form 'user@host' or 'user@host:port'). This can be
1882        overridden on a per-remote basis; see `remote.<name>.proxyAuthMethod`.
1883        Both can be overridden by the `GIT_HTTP_PROXY_AUTHMETHOD` environment
1884        variable.  Possible values are:
1885+
1886--
1887* `anyauth` - Automatically pick a suitable authentication method. It is
1888  assumed that the proxy answers an unauthenticated request with a 407
1889  status code and one or more Proxy-authenticate headers with supported
1890  authentication methods. This is the default.
1891* `basic` - HTTP Basic authentication
1892* `digest` - HTTP Digest authentication; this prevents the password from being
1893  transmitted to the proxy in clear text
1894* `negotiate` - GSS-Negotiate authentication (compare the --negotiate option
1895  of `curl(1)`)
1896* `ntlm` - NTLM authentication (compare the --ntlm option of `curl(1)`)
1897--
1898
1899http.emptyAuth::
1900        Attempt authentication without seeking a username or password.  This
1901        can be used to attempt GSS-Negotiate authentication without specifying
1902        a username in the URL, as libcurl normally requires a username for
1903        authentication.
1904
1905http.delegation::
1906        Control GSSAPI credential delegation. The delegation is disabled
1907        by default in libcurl since version 7.21.7. Set parameter to tell
1908        the server what it is allowed to delegate when it comes to user
1909        credentials. Used with GSS/kerberos. Possible values are:
1910+
1911--
1912* `none` - Don't allow any delegation.
1913* `policy` - Delegates if and only if the OK-AS-DELEGATE flag is set in the
1914  Kerberos service ticket, which is a matter of realm policy.
1915* `always` - Unconditionally allow the server to delegate.
1916--
1917
1918
1919http.extraHeader::
1920        Pass an additional HTTP header when communicating with a server.  If
1921        more than one such entry exists, all of them are added as extra
1922        headers.  To allow overriding the settings inherited from the system
1923        config, an empty value will reset the extra headers to the empty list.
1924
1925http.cookieFile::
1926        The pathname of a file containing previously stored cookie lines,
1927        which should be used
1928        in the Git http session, if they match the server. The file format
1929        of the file to read cookies from should be plain HTTP headers or
1930        the Netscape/Mozilla cookie file format (see `curl(1)`).
1931        NOTE that the file specified with http.cookieFile is used only as
1932        input unless http.saveCookies is set.
1933
1934http.saveCookies::
1935        If set, store cookies received during requests to the file specified by
1936        http.cookieFile. Has no effect if http.cookieFile is unset.
1937
1938http.sslVersion::
1939        The SSL version to use when negotiating an SSL connection, if you
1940        want to force the default.  The available and default version
1941        depend on whether libcurl was built against NSS or OpenSSL and the
1942        particular configuration of the crypto library in use. Internally
1943        this sets the 'CURLOPT_SSL_VERSION' option; see the libcurl
1944        documentation for more details on the format of this option and
1945        for the ssl version supported. Actually the possible values of
1946        this option are:
1947
1948        - sslv2
1949        - sslv3
1950        - tlsv1
1951        - tlsv1.0
1952        - tlsv1.1
1953        - tlsv1.2
1954        - tlsv1.3
1955
1956+
1957Can be overridden by the `GIT_SSL_VERSION` environment variable.
1958To force git to use libcurl's default ssl version and ignore any
1959explicit http.sslversion option, set `GIT_SSL_VERSION` to the
1960empty string.
1961
1962http.sslCipherList::
1963  A list of SSL ciphers to use when negotiating an SSL connection.
1964  The available ciphers depend on whether libcurl was built against
1965  NSS or OpenSSL and the particular configuration of the crypto
1966  library in use.  Internally this sets the 'CURLOPT_SSL_CIPHER_LIST'
1967  option; see the libcurl documentation for more details on the format
1968  of this list.
1969+
1970Can be overridden by the `GIT_SSL_CIPHER_LIST` environment variable.
1971To force git to use libcurl's default cipher list and ignore any
1972explicit http.sslCipherList option, set `GIT_SSL_CIPHER_LIST` to the
1973empty string.
1974
1975http.sslVerify::
1976        Whether to verify the SSL certificate when fetching or pushing
1977        over HTTPS. Defaults to true. Can be overridden by the
1978        `GIT_SSL_NO_VERIFY` environment variable.
1979
1980http.sslCert::
1981        File containing the SSL certificate when fetching or pushing
1982        over HTTPS. Can be overridden by the `GIT_SSL_CERT` environment
1983        variable.
1984
1985http.sslKey::
1986        File containing the SSL private key when fetching or pushing
1987        over HTTPS. Can be overridden by the `GIT_SSL_KEY` environment
1988        variable.
1989
1990http.sslCertPasswordProtected::
1991        Enable Git's password prompt for the SSL certificate.  Otherwise
1992        OpenSSL will prompt the user, possibly many times, if the
1993        certificate or private key is encrypted.  Can be overridden by the
1994        `GIT_SSL_CERT_PASSWORD_PROTECTED` environment variable.
1995
1996http.sslCAInfo::
1997        File containing the certificates to verify the peer with when
1998        fetching or pushing over HTTPS. Can be overridden by the
1999        `GIT_SSL_CAINFO` environment variable.
2000
2001http.sslCAPath::
2002        Path containing files with the CA certificates to verify the peer
2003        with when fetching or pushing over HTTPS. Can be overridden
2004        by the `GIT_SSL_CAPATH` environment variable.
2005
2006http.pinnedpubkey::
2007        Public key of the https service. It may either be the filename of
2008        a PEM or DER encoded public key file or a string starting with
2009        'sha256//' followed by the base64 encoded sha256 hash of the
2010        public key. See also libcurl 'CURLOPT_PINNEDPUBLICKEY'. git will
2011        exit with an error if this option is set but not supported by
2012        cURL.
2013
2014http.sslTry::
2015        Attempt to use AUTH SSL/TLS and encrypted data transfers
2016        when connecting via regular FTP protocol. This might be needed
2017        if the FTP server requires it for security reasons or you wish
2018        to connect securely whenever remote FTP server supports it.
2019        Default is false since it might trigger certificate verification
2020        errors on misconfigured servers.
2021
2022http.maxRequests::
2023        How many HTTP requests to launch in parallel. Can be overridden
2024        by the `GIT_HTTP_MAX_REQUESTS` environment variable. Default is 5.
2025
2026http.minSessions::
2027        The number of curl sessions (counted across slots) to be kept across
2028        requests. They will not be ended with curl_easy_cleanup() until
2029        http_cleanup() is invoked. If USE_CURL_MULTI is not defined, this
2030        value will be capped at 1. Defaults to 1.
2031
2032http.postBuffer::
2033        Maximum size in bytes of the buffer used by smart HTTP
2034        transports when POSTing data to the remote system.
2035        For requests larger than this buffer size, HTTP/1.1 and
2036        Transfer-Encoding: chunked is used to avoid creating a
2037        massive pack file locally.  Default is 1 MiB, which is
2038        sufficient for most requests.
2039
2040http.lowSpeedLimit, http.lowSpeedTime::
2041        If the HTTP transfer speed is less than 'http.lowSpeedLimit'
2042        for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
2043        Can be overridden by the `GIT_HTTP_LOW_SPEED_LIMIT` and
2044        `GIT_HTTP_LOW_SPEED_TIME` environment variables.
2045
2046http.noEPSV::
2047        A boolean which disables using of EPSV ftp command by curl.
2048        This can helpful with some "poor" ftp servers which don't
2049        support EPSV mode. Can be overridden by the `GIT_CURL_FTP_NO_EPSV`
2050        environment variable. Default is false (curl will use EPSV).
2051
2052http.userAgent::
2053        The HTTP USER_AGENT string presented to an HTTP server.  The default
2054        value represents the version of the client Git such as git/1.7.1.
2055        This option allows you to override this value to a more common value
2056        such as Mozilla/4.0.  This may be necessary, for instance, if
2057        connecting through a firewall that restricts HTTP connections to a set
2058        of common USER_AGENT strings (but not including those like git/1.7.1).
2059        Can be overridden by the `GIT_HTTP_USER_AGENT` environment variable.
2060
2061http.followRedirects::
2062        Whether git should follow HTTP redirects. If set to `true`, git
2063        will transparently follow any redirect issued by a server it
2064        encounters. If set to `false`, git will treat all redirects as
2065        errors. If set to `initial`, git will follow redirects only for
2066        the initial request to a remote, but not for subsequent
2067        follow-up HTTP requests. Since git uses the redirected URL as
2068        the base for the follow-up requests, this is generally
2069        sufficient. The default is `initial`.
2070
2071http.<url>.*::
2072        Any of the http.* options above can be applied selectively to some URLs.
2073        For a config key to match a URL, each element of the config key is
2074        compared to that of the URL, in the following order:
2075+
2076--
2077. Scheme (e.g., `https` in `https://example.com/`). This field
2078  must match exactly between the config key and the URL.
2079
2080. Host/domain name (e.g., `example.com` in `https://example.com/`).
2081  This field must match between the config key and the URL. It is
2082  possible to specify a `*` as part of the host name to match all subdomains
2083  at this level. `https://*.example.com/` for example would match
2084  `https://foo.example.com/`, but not `https://foo.bar.example.com/`.
2085
2086. Port number (e.g., `8080` in `http://example.com:8080/`).
2087  This field must match exactly between the config key and the URL.
2088  Omitted port numbers are automatically converted to the correct
2089  default for the scheme before matching.
2090
2091. Path (e.g., `repo.git` in `https://example.com/repo.git`). The
2092  path field of the config key must match the path field of the URL
2093  either exactly or as a prefix of slash-delimited path elements.  This means
2094  a config key with path `foo/` matches URL path `foo/bar`.  A prefix can only
2095  match on a slash (`/`) boundary.  Longer matches take precedence (so a config
2096  key with path `foo/bar` is a better match to URL path `foo/bar` than a config
2097  key with just path `foo/`).
2098
2099. User name (e.g., `user` in `https://user@example.com/repo.git`). If
2100  the config key has a user name it must match the user name in the
2101  URL exactly. If the config key does not have a user name, that
2102  config key will match a URL with any user name (including none),
2103  but at a lower precedence than a config key with a user name.
2104--
2105+
2106The list above is ordered by decreasing precedence; a URL that matches
2107a config key's path is preferred to one that matches its user name. For example,
2108if the URL is `https://user@example.com/foo/bar` a config key match of
2109`https://example.com/foo` will be preferred over a config key match of
2110`https://user@example.com`.
2111+
2112All URLs are normalized before attempting any matching (the password part,
2113if embedded in the URL, is always ignored for matching purposes) so that
2114equivalent URLs that are simply spelled differently will match properly.
2115Environment variable settings always override any matches.  The URLs that are
2116matched against are those given directly to Git commands.  This means any URLs
2117visited as a result of a redirection do not participate in matching.
2118
2119ssh.variant::
2120        By default, Git determines the command line arguments to use
2121        based on the basename of the configured SSH command (configured
2122        using the environment variable `GIT_SSH` or `GIT_SSH_COMMAND` or
2123        the config setting `core.sshCommand`). If the basename is
2124        unrecognized, Git will attempt to detect support of OpenSSH
2125        options by first invoking the configured SSH command with the
2126        `-G` (print configuration) option and will subsequently use
2127        OpenSSH options (if that is successful) or no options besides
2128        the host and remote command (if it fails).
2129+
2130The config variable `ssh.variant` can be set to override this detection.
2131Valid values are `ssh` (to use OpenSSH options), `plink`, `putty`,
2132`tortoiseplink`, `simple` (no options except the host and remote command).
2133The default auto-detection can be explicitly requested using the value
2134`auto`.  Any other value is treated as `ssh`.  This setting can also be
2135overridden via the environment variable `GIT_SSH_VARIANT`.
2136+
2137The current command-line parameters used for each variant are as
2138follows:
2139+
2140--
2141
2142* `ssh` - [-p port] [-4] [-6] [-o option] [username@]host command
2143
2144* `simple` - [username@]host command
2145
2146* `plink` or `putty` - [-P port] [-4] [-6] [username@]host command
2147
2148* `tortoiseplink` - [-P port] [-4] [-6] -batch [username@]host command
2149
2150--
2151+
2152Except for the `simple` variant, command-line parameters are likely to
2153change as git gains new features.
2154
2155i18n.commitEncoding::
2156        Character encoding the commit messages are stored in; Git itself
2157        does not care per se, but this information is necessary e.g. when
2158        importing commits from emails or in the gitk graphical history
2159        browser (and possibly at other places in the future or in other
2160        porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.
2161
2162i18n.logOutputEncoding::
2163        Character encoding the commit messages are converted to when
2164        running 'git log' and friends.
2165
2166imap::
2167        The configuration variables in the 'imap' section are described
2168        in linkgit:git-imap-send[1].
2169
2170index.threads::
2171        Specifies the number of threads to spawn when loading the index.
2172        This is meant to reduce index load time on multiprocessor machines.
2173        Specifying 0 or 'true' will cause Git to auto-detect the number of
2174        CPU's and set the number of threads accordingly. Specifying 1 or
2175        'false' will disable multithreading. Defaults to 'true'.
2176
2177index.version::
2178        Specify the version with which new index files should be
2179        initialized.  This does not affect existing repositories.
2180
2181init.templateDir::
2182        Specify the directory from which templates will be copied.
2183        (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].)
2184
2185instaweb.browser::
2186        Specify the program that will be used to browse your working
2187        repository in gitweb. See linkgit:git-instaweb[1].
2188
2189instaweb.httpd::
2190        The HTTP daemon command-line to start gitweb on your working
2191        repository. See linkgit:git-instaweb[1].
2192
2193instaweb.local::
2194        If true the web server started by linkgit:git-instaweb[1] will
2195        be bound to the local IP (127.0.0.1).
2196
2197instaweb.modulePath::
2198        The default module path for linkgit:git-instaweb[1] to use
2199        instead of /usr/lib/apache2/modules.  Only used if httpd
2200        is Apache.
2201
2202instaweb.port::
2203        The port number to bind the gitweb httpd to. See
2204        linkgit:git-instaweb[1].
2205
2206interactive.singleKey::
2207        In interactive commands, allow the user to provide one-letter
2208        input with a single key (i.e., without hitting enter).
2209        Currently this is used by the `--patch` mode of
2210        linkgit:git-add[1], linkgit:git-checkout[1], linkgit:git-commit[1],
2211        linkgit:git-reset[1], and linkgit:git-stash[1]. Note that this
2212        setting is silently ignored if portable keystroke input
2213        is not available; requires the Perl module Term::ReadKey.
2214
2215interactive.diffFilter::
2216        When an interactive command (such as `git add --patch`) shows
2217        a colorized diff, git will pipe the diff through the shell
2218        command defined by this configuration variable. The command may
2219        mark up the diff further for human consumption, provided that it
2220        retains a one-to-one correspondence with the lines in the
2221        original diff. Defaults to disabled (no filtering).
2222
2223log.abbrevCommit::
2224        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
2225        linkgit:git-whatchanged[1] assume `--abbrev-commit`. You may
2226        override this option with `--no-abbrev-commit`.
2227
2228log.date::
2229        Set the default date-time mode for the 'log' command.
2230        Setting a value for log.date is similar to using 'git log''s
2231        `--date` option.  See linkgit:git-log[1] for details.
2232
2233log.decorate::
2234        Print out the ref names of any commits that are shown by the log
2235        command. If 'short' is specified, the ref name prefixes 'refs/heads/',
2236        'refs/tags/' and 'refs/remotes/' will not be printed. If 'full' is
2237        specified, the full ref name (including prefix) will be printed.
2238        If 'auto' is specified, then if the output is going to a terminal,
2239        the ref names are shown as if 'short' were given, otherwise no ref
2240        names are shown. This is the same as the `--decorate` option
2241        of the `git log`.
2242
2243log.follow::
2244        If `true`, `git log` will act as if the `--follow` option was used when
2245        a single <path> is given.  This has the same limitations as `--follow`,
2246        i.e. it cannot be used to follow multiple files and does not work well
2247        on non-linear history.
2248
2249log.graphColors::
2250        A list of colors, separated by commas, that can be used to draw
2251        history lines in `git log --graph`.
2252
2253log.showRoot::
2254        If true, the initial commit will be shown as a big creation event.
2255        This is equivalent to a diff against an empty tree.
2256        Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
2257        normally hide the root commit will now show it. True by default.
2258
2259log.showSignature::
2260        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
2261        linkgit:git-whatchanged[1] assume `--show-signature`.
2262
2263log.mailmap::
2264        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
2265        linkgit:git-whatchanged[1] assume `--use-mailmap`.
2266
2267mailinfo.scissors::
2268        If true, makes linkgit:git-mailinfo[1] (and therefore
2269        linkgit:git-am[1]) act by default as if the --scissors option
2270        was provided on the command-line. When active, this features
2271        removes everything from the message body before a scissors
2272        line (i.e. consisting mainly of ">8", "8<" and "-").
2273
2274mailmap.file::
2275        The location of an augmenting mailmap file. The default
2276        mailmap, located in the root of the repository, is loaded
2277        first, then the mailmap file pointed to by this variable.
2278        The location of the mailmap file may be in a repository
2279        subdirectory, or somewhere outside of the repository itself.
2280        See linkgit:git-shortlog[1] and linkgit:git-blame[1].
2281
2282mailmap.blob::
2283        Like `mailmap.file`, but consider the value as a reference to a
2284        blob in the repository. If both `mailmap.file` and
2285        `mailmap.blob` are given, both are parsed, with entries from
2286        `mailmap.file` taking precedence. In a bare repository, this
2287        defaults to `HEAD:.mailmap`. In a non-bare repository, it
2288        defaults to empty.
2289
2290man.viewer::
2291        Specify the programs that may be used to display help in the
2292        'man' format. See linkgit:git-help[1].
2293
2294man.<tool>.cmd::
2295        Specify the command to invoke the specified man viewer. The
2296        specified command is evaluated in shell with the man page
2297        passed as argument. (See linkgit:git-help[1].)
2298
2299man.<tool>.path::
2300        Override the path for the given tool that may be used to
2301        display help in the 'man' format. See linkgit:git-help[1].
2302
2303include::merge-config.txt[]
2304
2305mergetool.<tool>.path::
2306        Override the path for the given tool.  This is useful in case
2307        your tool is not in the PATH.
2308
2309mergetool.<tool>.cmd::
2310        Specify the command to invoke the specified merge tool.  The
2311        specified command is evaluated in shell with the following
2312        variables available: 'BASE' is the name of a temporary file
2313        containing the common base of the files to be merged, if available;
2314        'LOCAL' is the name of a temporary file containing the contents of
2315        the file on the current branch; 'REMOTE' is the name of a temporary
2316        file containing the contents of the file from the branch being
2317        merged; 'MERGED' contains the name of the file to which the merge
2318        tool should write the results of a successful merge.
2319
2320mergetool.<tool>.trustExitCode::
2321        For a custom merge command, specify whether the exit code of
2322        the merge command can be used to determine whether the merge was
2323        successful.  If this is not set to true then the merge target file
2324        timestamp is checked and the merge assumed to have been successful
2325        if the file has been updated, otherwise the user is prompted to
2326        indicate the success of the merge.
2327
2328mergetool.meld.hasOutput::
2329        Older versions of `meld` do not support the `--output` option.
2330        Git will attempt to detect whether `meld` supports `--output`
2331        by inspecting the output of `meld --help`.  Configuring
2332        `mergetool.meld.hasOutput` will make Git skip these checks and
2333        use the configured value instead.  Setting `mergetool.meld.hasOutput`
2334        to `true` tells Git to unconditionally use the `--output` option,
2335        and `false` avoids using `--output`.
2336
2337mergetool.keepBackup::
2338        After performing a merge, the original file with conflict markers
2339        can be saved as a file with a `.orig` extension.  If this variable
2340        is set to `false` then this file is not preserved.  Defaults to
2341        `true` (i.e. keep the backup files).
2342
2343mergetool.keepTemporaries::
2344        When invoking a custom merge tool, Git uses a set of temporary
2345        files to pass to the tool. If the tool returns an error and this
2346        variable is set to `true`, then these temporary files will be
2347        preserved, otherwise they will be removed after the tool has
2348        exited. Defaults to `false`.
2349
2350mergetool.writeToTemp::
2351        Git writes temporary 'BASE', 'LOCAL', and 'REMOTE' versions of
2352        conflicting files in the worktree by default.  Git will attempt
2353        to use a temporary directory for these files when set `true`.
2354        Defaults to `false`.
2355
2356mergetool.prompt::
2357        Prompt before each invocation of the merge resolution program.
2358
2359notes.mergeStrategy::
2360        Which merge strategy to choose by default when resolving notes
2361        conflicts.  Must be one of `manual`, `ours`, `theirs`, `union`, or
2362        `cat_sort_uniq`.  Defaults to `manual`.  See "NOTES MERGE STRATEGIES"
2363        section of linkgit:git-notes[1] for more information on each strategy.
2364
2365notes.<name>.mergeStrategy::
2366        Which merge strategy to choose when doing a notes merge into
2367        refs/notes/<name>.  This overrides the more general
2368        "notes.mergeStrategy".  See the "NOTES MERGE STRATEGIES" section in
2369        linkgit:git-notes[1] for more information on the available strategies.
2370
2371notes.displayRef::
2372        The (fully qualified) refname from which to show notes when
2373        showing commit messages.  The value of this variable can be set
2374        to a glob, in which case notes from all matching refs will be
2375        shown.  You may also specify this configuration variable
2376        several times.  A warning will be issued for refs that do not
2377        exist, but a glob that does not match any refs is silently
2378        ignored.
2379+
2380This setting can be overridden with the `GIT_NOTES_DISPLAY_REF`
2381environment variable, which must be a colon separated list of refs or
2382globs.
2383+
2384The effective value of "core.notesRef" (possibly overridden by
2385GIT_NOTES_REF) is also implicitly added to the list of refs to be
2386displayed.
2387
2388notes.rewrite.<command>::
2389        When rewriting commits with <command> (currently `amend` or
2390        `rebase`) and this variable is set to `true`, Git
2391        automatically copies your notes from the original to the
2392        rewritten commit.  Defaults to `true`, but see
2393        "notes.rewriteRef" below.
2394
2395notes.rewriteMode::
2396        When copying notes during a rewrite (see the
2397        "notes.rewrite.<command>" option), determines what to do if
2398        the target commit already has a note.  Must be one of
2399        `overwrite`, `concatenate`, `cat_sort_uniq`, or `ignore`.
2400        Defaults to `concatenate`.
2401+
2402This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
2403environment variable.
2404
2405notes.rewriteRef::
2406        When copying notes during a rewrite, specifies the (fully
2407        qualified) ref whose notes should be copied.  The ref may be a
2408        glob, in which case notes in all matching refs will be copied.
2409        You may also specify this configuration several times.
2410+
2411Does not have a default value; you must configure this variable to
2412enable note rewriting.  Set it to `refs/notes/commits` to enable
2413rewriting for the default commit notes.
2414+
2415This setting can be overridden with the `GIT_NOTES_REWRITE_REF`
2416environment variable, which must be a colon separated list of refs or
2417globs.
2418
2419pack.window::
2420        The size of the window used by linkgit:git-pack-objects[1] when no
2421        window size is given on the command line. Defaults to 10.
2422
2423pack.depth::
2424        The maximum delta depth used by linkgit:git-pack-objects[1] when no
2425        maximum depth is given on the command line. Defaults to 50.
2426        Maximum value is 4095.
2427
2428pack.windowMemory::
2429        The maximum size of memory that is consumed by each thread
2430        in linkgit:git-pack-objects[1] for pack window memory when
2431        no limit is given on the command line.  The value can be
2432        suffixed with "k", "m", or "g".  When left unconfigured (or
2433        set explicitly to 0), there will be no limit.
2434
2435pack.compression::
2436        An integer -1..9, indicating the compression level for objects
2437        in a pack file. -1 is the zlib default. 0 means no
2438        compression, and 1..9 are various speed/size tradeoffs, 9 being
2439        slowest.  If not set,  defaults to core.compression.  If that is
2440        not set,  defaults to -1, the zlib default, which is "a default
2441        compromise between speed and compression (currently equivalent
2442        to level 6)."
2443+
2444Note that changing the compression level will not automatically recompress
2445all existing objects. You can force recompression by passing the -F option
2446to linkgit:git-repack[1].
2447
2448pack.island::
2449        An extended regular expression configuring a set of delta
2450        islands. See "DELTA ISLANDS" in linkgit:git-pack-objects[1]
2451        for details.
2452
2453pack.islandCore::
2454        Specify an island name which gets to have its objects be
2455        packed first. This creates a kind of pseudo-pack at the front
2456        of one pack, so that the objects from the specified island are
2457        hopefully faster to copy into any pack that should be served
2458        to a user requesting these objects. In practice this means
2459        that the island specified should likely correspond to what is
2460        the most commonly cloned in the repo. See also "DELTA ISLANDS"
2461        in linkgit:git-pack-objects[1].
2462
2463pack.deltaCacheSize::
2464        The maximum memory in bytes used for caching deltas in
2465        linkgit:git-pack-objects[1] before writing them out to a pack.
2466        This cache is used to speed up the writing object phase by not
2467        having to recompute the final delta result once the best match
2468        for all objects is found.  Repacking large repositories on machines
2469        which are tight with memory might be badly impacted by this though,
2470        especially if this cache pushes the system into swapping.
2471        A value of 0 means no limit. The smallest size of 1 byte may be
2472        used to virtually disable this cache. Defaults to 256 MiB.
2473
2474pack.deltaCacheLimit::
2475        The maximum size of a delta, that is cached in
2476        linkgit:git-pack-objects[1]. This cache is used to speed up the
2477        writing object phase by not having to recompute the final delta
2478        result once the best match for all objects is found.
2479        Defaults to 1000. Maximum value is 65535.
2480
2481pack.threads::
2482        Specifies the number of threads to spawn when searching for best
2483        delta matches.  This requires that linkgit:git-pack-objects[1]
2484        be compiled with pthreads otherwise this option is ignored with a
2485        warning. This is meant to reduce packing time on multiprocessor
2486        machines. The required amount of memory for the delta search window
2487        is however multiplied by the number of threads.
2488        Specifying 0 will cause Git to auto-detect the number of CPU's
2489        and set the number of threads accordingly.
2490
2491pack.indexVersion::
2492        Specify the default pack index version.  Valid values are 1 for
2493        legacy pack index used by Git versions prior to 1.5.2, and 2 for
2494        the new pack index with capabilities for packs larger than 4 GB
2495        as well as proper protection against the repacking of corrupted
2496        packs.  Version 2 is the default.  Note that version 2 is enforced
2497        and this config option ignored whenever the corresponding pack is
2498        larger than 2 GB.
2499+
2500If you have an old Git that does not understand the version 2 `*.idx` file,
2501cloning or fetching over a non native protocol (e.g. "http")
2502that will copy both `*.pack` file and corresponding `*.idx` file from the
2503other side may give you a repository that cannot be accessed with your
2504older version of Git. If the `*.pack` file is smaller than 2 GB, however,
2505you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
2506the `*.idx` file.
2507
2508pack.packSizeLimit::
2509        The maximum size of a pack.  This setting only affects
2510        packing to a file when repacking, i.e. the git:// protocol
2511        is unaffected.  It can be overridden by the `--max-pack-size`
2512        option of linkgit:git-repack[1].  Reaching this limit results
2513        in the creation of multiple packfiles; which in turn prevents
2514        bitmaps from being created.
2515        The minimum size allowed is limited to 1 MiB.
2516        The default is unlimited.
2517        Common unit suffixes of 'k', 'm', or 'g' are
2518        supported.
2519
2520pack.useBitmaps::
2521        When true, git will use pack bitmaps (if available) when packing
2522        to stdout (e.g., during the server side of a fetch). Defaults to
2523        true. You should not generally need to turn this off unless
2524        you are debugging pack bitmaps.
2525
2526pack.writeBitmaps (deprecated)::
2527        This is a deprecated synonym for `repack.writeBitmaps`.
2528
2529pack.writeBitmapHashCache::
2530        When true, git will include a "hash cache" section in the bitmap
2531        index (if one is written). This cache can be used to feed git's
2532        delta heuristics, potentially leading to better deltas between
2533        bitmapped and non-bitmapped objects (e.g., when serving a fetch
2534        between an older, bitmapped pack and objects that have been
2535        pushed since the last gc). The downside is that it consumes 4
2536        bytes per object of disk space, and that JGit's bitmap
2537        implementation does not understand it, causing it to complain if
2538        Git and JGit are used on the same repository. Defaults to false.
2539
2540pager.<cmd>::
2541        If the value is boolean, turns on or off pagination of the
2542        output of a particular Git subcommand when writing to a tty.
2543        Otherwise, turns on pagination for the subcommand using the
2544        pager specified by the value of `pager.<cmd>`.  If `--paginate`
2545        or `--no-pager` is specified on the command line, it takes
2546        precedence over this option.  To disable pagination for all
2547        commands, set `core.pager` or `GIT_PAGER` to `cat`.
2548
2549pretty.<name>::
2550        Alias for a --pretty= format string, as specified in
2551        linkgit:git-log[1]. Any aliases defined here can be used just
2552        as the built-in pretty formats could. For example,
2553        running `git config pretty.changelog "format:* %H %s"`
2554        would cause the invocation `git log --pretty=changelog`
2555        to be equivalent to running `git log "--pretty=format:* %H %s"`.
2556        Note that an alias with the same name as a built-in format
2557        will be silently ignored.
2558
2559protocol.allow::
2560        If set, provide a user defined default policy for all protocols which
2561        don't explicitly have a policy (`protocol.<name>.allow`).  By default,
2562        if unset, known-safe protocols (http, https, git, ssh, file) have a
2563        default policy of `always`, known-dangerous protocols (ext) have a
2564        default policy of `never`, and all other protocols have a default
2565        policy of `user`.  Supported policies:
2566+
2567--
2568
2569* `always` - protocol is always able to be used.
2570
2571* `never` - protocol is never able to be used.
2572
2573* `user` - protocol is only able to be used when `GIT_PROTOCOL_FROM_USER` is
2574  either unset or has a value of 1.  This policy should be used when you want a
2575  protocol to be directly usable by the user but don't want it used by commands which
2576  execute clone/fetch/push commands without user input, e.g. recursive
2577  submodule initialization.
2578
2579--
2580
2581protocol.<name>.allow::
2582        Set a policy to be used by protocol `<name>` with clone/fetch/push
2583        commands. See `protocol.allow` above for the available policies.
2584+
2585The protocol names currently used by git are:
2586+
2587--
2588  - `file`: any local file-based path (including `file://` URLs,
2589    or local paths)
2590
2591  - `git`: the anonymous git protocol over a direct TCP
2592    connection (or proxy, if configured)
2593
2594  - `ssh`: git over ssh (including `host:path` syntax,
2595    `ssh://`, etc).
2596
2597  - `http`: git over http, both "smart http" and "dumb http".
2598    Note that this does _not_ include `https`; if you want to configure
2599    both, you must do so individually.
2600
2601  - any external helpers are named by their protocol (e.g., use
2602    `hg` to allow the `git-remote-hg` helper)
2603--
2604
2605protocol.version::
2606        Experimental. If set, clients will attempt to communicate with a
2607        server using the specified protocol version.  If unset, no
2608        attempt will be made by the client to communicate using a
2609        particular protocol version, this results in protocol version 0
2610        being used.
2611        Supported versions:
2612+
2613--
2614
2615* `0` - the original wire protocol.
2616
2617* `1` - the original wire protocol with the addition of a version string
2618  in the initial response from the server.
2619
2620* `2` - link:technical/protocol-v2.html[wire protocol version 2].

2632remote.pushDefault::
2633        The remote to push to by default.  Overrides
2634        `branch.<name>.remote` for all branches, and is overridden by
2635        `branch.<name>.pushRemote` for specific branches.
2636
2637remote.<name>.url::
2638        The URL of a remote repository.  See linkgit:git-fetch[1] or
2639        linkgit:git-push[1].
2640
2641remote.<name>.pushurl::
2642        The push URL of a remote repository.  See linkgit:git-push[1].
2643
2644remote.<name>.proxy::
2645        For remotes that require curl (http, https and ftp), the URL to
2646        the proxy to use for that remote.  Set to the empty string to
2647        disable proxying for that remote.
2648
2649remote.<name>.proxyAuthMethod::
2650        For remotes that require curl (http, https and ftp), the method to use for
2651        authenticating against the proxy in use (probably set in
2652        `remote.<name>.proxy`). See `http.proxyAuthMethod`.
2653
2654remote.<name>.fetch::
2655        The default set of "refspec" for linkgit:git-fetch[1]. See
2656        linkgit:git-fetch[1].
2657
2658remote.<name>.push::
2659        The default set of "refspec" for linkgit:git-push[1]. See
2660        linkgit:git-push[1].
2661
2662remote.<name>.mirror::
2663        If true, pushing to this remote will automatically behave
2664        as if the `--mirror` option was given on the command line.
2665
2666remote.<name>.skipDefaultUpdate::
2667        If true, this remote will be skipped by default when updating
2668        using linkgit:git-fetch[1] or the `update` subcommand of
2669        linkgit:git-remote[1].
2670
2671remote.<name>.skipFetchAll::
2672        If true, this remote will be skipped by default when updating
2673        using linkgit:git-fetch[1] or the `update` subcommand of
2674        linkgit:git-remote[1].
2675
2676remote.<name>.receivepack::
2677        The default program to execute on the remote side when pushing.  See
2678        option --receive-pack of linkgit:git-push[1].
2679
2680remote.<name>.uploadpack::
2681        The default program to execute on the remote side when fetching.  See
2682        option --upload-pack of linkgit:git-fetch-pack[1].
2683
2684remote.<name>.tagOpt::
2685        Setting this value to --no-tags disables automatic tag following when
2686        fetching from remote <name>. Setting it to --tags will fetch every
2687        tag from remote <name>, even if they are not reachable from remote
2688        branch heads. Passing these flags directly to linkgit:git-fetch[1] can
2689        override this setting. See options --tags and --no-tags of
2690        linkgit:git-fetch[1].
2691
2692remote.<name>.vcs::
2693        Setting this to a value <vcs> will cause Git to interact with
2694        the remote with the git-remote-<vcs> helper.
2695
2696remote.<name>.prune::
2697        When set to true, fetching from this remote by default will also
2698        remove any remote-tracking references that no longer exist on the
2699        remote (as if the `--prune` option was given on the command line).
2700        Overrides `fetch.prune` settings, if any.
2701
2702remote.<name>.pruneTags::
2703        When set to true, fetching from this remote by default will also
2704        remove any local tags that no longer exist on the remote if pruning
2705        is activated in general via `remote.<name>.prune`, `fetch.prune` or
2706        `--prune`. Overrides `fetch.pruneTags` settings, if any.
2707+
2708See also `remote.<name>.prune` and the PRUNING section of
2709linkgit:git-fetch[1].
2710
2711remotes.<group>::
2712        The list of remotes which are fetched by "git remote update
2713        <group>".  See linkgit:git-remote[1].
2714
2715repack.useDeltaBaseOffset::
2716        By default, linkgit:git-repack[1] creates packs that use
2717        delta-base offset. If you need to share your repository with
2718        Git older than version 1.4.4, either directly or via a dumb
2719        protocol such as http, then you need to set this option to
2720        "false" and repack. Access from old Git versions over the
2721        native protocol are unaffected by this option.
2722
2723repack.packKeptObjects::
2724        If set to true, makes `git repack` act as if
2725        `--pack-kept-objects` was passed. See linkgit:git-repack[1] for
2726        details. Defaults to `false` normally, but `true` if a bitmap
2727        index is being written (either via `--write-bitmap-index` or
2728        `repack.writeBitmaps`).
2729
2730repack.useDeltaIslands::
2731        If set to true, makes `git repack` act as if `--delta-islands`
2732        was passed. Defaults to `false`.
2733
2734repack.writeBitmaps::
2735        When true, git will write a bitmap index when packing all
2736        objects to disk (e.g., when `git repack -a` is run).  This
2737        index can speed up the "counting objects" phase of subsequent
2738        packs created for clones and fetches, at the cost of some disk
2739        space and extra time spent on the initial repack.  This has
2740        no effect if multiple packfiles are created.
2741        Defaults to false.
2742
2743rerere.autoUpdate::
2744        When set to true, `git-rerere` updates the index with the
2745        resulting contents after it cleanly resolves conflicts using
2746        previously recorded resolution.  Defaults to false.
2747
2748rerere.enabled::
2749        Activate recording of resolved conflicts, so that identical
2750        conflict hunks can be resolved automatically, should they be
2751        encountered again.  By default, linkgit:git-rerere[1] is
2752        enabled if there is an `rr-cache` directory under the
2753        `$GIT_DIR`, e.g. if "rerere" was previously used in the
2754        repository.
2755
2756include::sendemail-config.txt[]
2757
2758sequence.editor::
2759        Text editor used by `git rebase -i` for editing the rebase instruction file.
2760        The value is meant to be interpreted by the shell when it is used.
2761        It can be overridden by the `GIT_SEQUENCE_EDITOR` environment variable.
2762        When not configured the default commit message editor is used instead.
2763
2764showBranch.default::
2765        The default set of branches for linkgit:git-show-branch[1].
2766        See linkgit:git-show-branch[1].
2767
2768splitIndex.maxPercentChange::
2769        When the split index feature is used, this specifies the
2770        percent of entries the split index can contain compared to the
2771        total number of entries in both the split index and the shared
2772        index before a new shared index is written.
2773        The value should be between 0 and 100. If the value is 0 then
2774        a new shared index is always written, if it is 100 a new
2775        shared index is never written.
2776        By default the value is 20, so a new shared index is written
2777        if the number of entries in the split index would be greater
2778        than 20 percent of the total number of entries.
2779        See linkgit:git-update-index[1].
2780
2781splitIndex.sharedIndexExpire::
2782        When the split index feature is used, shared index files that
2783        were not modified since the time this variable specifies will
2784        be removed when a new shared index file is created. The value
2785        "now" expires all entries immediately, and "never" suppresses
2786        expiration altogether.
2787        The default value is "2.weeks.ago".
2788        Note that a shared index file is considered modified (for the
2789        purpose of expiration) each time a new split-index file is
2790        either created based on it or read from it.
2791        See linkgit:git-update-index[1].
2792
2793status.relativePaths::
2794        By default, linkgit:git-status[1] shows paths relative to the
2795        current directory. Setting this variable to `false` shows paths
2796        relative to the repository root (this was the default for Git
2797        prior to v1.5.4).
2798
2799status.short::
2800        Set to true to enable --short by default in linkgit:git-status[1].
2801        The option --no-short takes precedence over this variable.
2802
2803status.branch::
2804        Set to true to enable --branch by default in linkgit:git-status[1].
2805        The option --no-branch takes precedence over this variable.
2806
2807status.displayCommentPrefix::
2808        If set to true, linkgit:git-status[1] will insert a comment
2809        prefix before each output line (starting with
2810        `core.commentChar`, i.e. `#` by default). This was the
2811        behavior of linkgit:git-status[1] in Git 1.8.4 and previous.
2812        Defaults to false.
2813
2814status.renameLimit::
2815        The number of files to consider when performing rename detection
2816        in linkgit:git-status[1] and linkgit:git-commit[1]. Defaults to
2817        the value of diff.renameLimit.
2818
2819status.renames::
2820        Whether and how Git detects renames in linkgit:git-status[1] and
2821        linkgit:git-commit[1] .  If set to "false", rename detection is
2822        disabled. If set to "true", basic rename detection is enabled.
2823        If set to "copies" or "copy", Git will detect copies, as well.
2824        Defaults to the value of diff.renames.
2825
2826status.showStash::
2827        If set to true, linkgit:git-status[1] will display the number of
2828        entries currently stashed away.
2829        Defaults to false.
2830
2831status.showUntrackedFiles::
2832        By default, linkgit:git-status[1] and linkgit:git-commit[1] show
2833        files which are not currently tracked by Git. Directories which
2834        contain only untracked files, are shown with the directory name
2835        only. Showing untracked files means that Git needs to lstat() all
2836        the files in the whole repository, which might be slow on some
2837        systems. So, this variable controls how the commands displays
2838        the untracked files. Possible values are:
2839+
2840--
2841* `no` - Show no untracked files.
2842* `normal` - Show untracked files and directories.
2843* `all` - Show also individual files in untracked directories.
2844--
2845+
2846If this variable is not specified, it defaults to 'normal'.
2847This variable can be overridden with the -u|--untracked-files option
2848of linkgit:git-status[1] and linkgit:git-commit[1].
2849
2850status.submoduleSummary::
2851        Defaults to false.
2852        If this is set to a non zero number or true (identical to -1 or an
2853        unlimited number), the submodule summary will be enabled and a
2854        summary of commits for modified submodules will be shown (see
2855        --summary-limit option of linkgit:git-submodule[1]). Please note
2856        that the summary output command will be suppressed for all
2857        submodules when `diff.ignoreSubmodules` is set to 'all' or only
2858        for those submodules where `submodule.<name>.ignore=all`. The only
2859        exception to that rule is that status and commit will show staged
2860        submodule changes. To
2861        also view the summary for ignored submodules you can either use
2862        the --ignore-submodules=dirty command-line option or the 'git
2863        submodule summary' command, which shows a similar output but does
2864        not honor these settings.
2865
2866stash.showPatch::
2867        If this is set to true, the `git stash show` command without an
2868        option will show the stash entry in patch form.  Defaults to false.
2869        See description of 'show' command in linkgit:git-stash[1].
2870
2871stash.showStat::
2872        If this is set to true, the `git stash show` command without an
2873        option will show diffstat of the stash entry.  Defaults to true.
2874        See description of 'show' command in linkgit:git-stash[1].
2875
2876include::submodule-config.txt[]
2877
2878tag.forceSignAnnotated::
2879        A boolean to specify whether annotated tags created should be GPG signed.
2880        If `--annotate` is specified on the command line, it takes
2881        precedence over this option.
2882
2883tag.sort::
2884        This variable controls the sort ordering of tags when displayed by
2885        linkgit:git-tag[1]. Without the "--sort=<value>" option provided, the
2886        value of this variable will be used as the default.
2887
2888tar.umask::
2889        This variable can be used to restrict the permission bits of
2890        tar archive entries.  The default is 0002, which turns off the
2891        world write bit.  The special value "user" indicates that the
2892        archiving user's umask will be used instead.  See umask(2) and
2893        linkgit:git-archive[1].
2894
2895transfer.fsckObjects::
2896        When `fetch.fsckObjects` or `receive.fsckObjects` are
2897        not set, the value of this variable is used instead.
2898        Defaults to false.
2899+
2900When set, the fetch or receive will abort in the case of a malformed
2901object or a link to a nonexistent object. In addition, various other
2902issues are checked for, including legacy issues (see `fsck.<msg-id>`),
2903and potential security issues like the existence of a `.GIT` directory
2904or a malicious `.gitmodules` file (see the release notes for v2.2.1
2905and v2.17.1 for details). Other sanity and security checks may be
2906added in future releases.
2907+
2908On the receiving side, failing fsckObjects will make those objects
2909unreachable, see "QUARANTINE ENVIRONMENT" in
2910linkgit:git-receive-pack[1]. On the fetch side, malformed objects will
2911instead be left unreferenced in the repository.
2912+
2913Due to the non-quarantine nature of the `fetch.fsckObjects`
2914implementation it can not be relied upon to leave the object store
2915clean like `receive.fsckObjects` can.
2916+
2917As objects are unpacked they're written to the object store, so there
2918can be cases where malicious objects get introduced even though the
2919"fetch" failed, only to have a subsequent "fetch" succeed because only
2920new incoming objects are checked, not those that have already been
2921written to the object store. That difference in behavior should not be
2922relied upon. In the future, such objects may be quarantined for
2923"fetch" as well.
2924+
2925For now, the paranoid need to find some way to emulate the quarantine
2926environment if they'd like the same protection as "push". E.g. in the
2927case of an internal mirror do the mirroring in two steps, one to fetch
2928the untrusted objects, and then do a second "push" (which will use the
2929quarantine) to another internal repo, and have internal clients
2930consume this pushed-to repository, or embargo internal fetches and
2931only allow them once a full "fsck" has run (and no new fetches have
2932happened in the meantime).
2933
2934transfer.hideRefs::
2935        String(s) `receive-pack` and `upload-pack` use to decide which
2936        refs to omit from their initial advertisements.  Use more than
2937        one definition to specify multiple prefix strings. A ref that is
2938        under the hierarchies listed in the value of this variable is
2939        excluded, and is hidden when responding to `git push` or `git
2940        fetch`.  See `receive.hideRefs` and `uploadpack.hideRefs` for
2941        program-specific versions of this config.
2942+
2943You may also include a `!` in front of the ref name to negate the entry,
2944explicitly exposing it, even if an earlier entry marked it as hidden.
2945If you have multiple hideRefs values, later entries override earlier ones
2946(and entries in more-specific config files override less-specific ones).
2947+
2948If a namespace is in use, the namespace prefix is stripped from each
2949reference before it is matched against `transfer.hiderefs` patterns.
2950For example, if `refs/heads/master` is specified in `transfer.hideRefs` and
2951the current namespace is `foo`, then `refs/namespaces/foo/refs/heads/master`
2952is omitted from the advertisements but `refs/heads/master` and
2953`refs/namespaces/bar/refs/heads/master` are still advertised as so-called
2954"have" lines. In order to match refs before stripping, add a `^` in front of
2955the ref name. If you combine `!` and `^`, `!` must be specified first.
2956+
2957Even if you hide refs, a client may still be able to steal the target
2958objects via the techniques described in the "SECURITY" section of the
2959linkgit:gitnamespaces[7] man page; it's best to keep private data in a
2960separate repository.
2961
2962transfer.unpackLimit::
2963        When `fetch.unpackLimit` or `receive.unpackLimit` are
2964        not set, the value of this variable is used instead.
2965        The default value is 100.
2966
2967uploadarchive.allowUnreachable::
2968        If true, allow clients to use `git archive --remote` to request
2969        any tree, whether reachable from the ref tips or not. See the
2970        discussion in the "SECURITY" section of
2971        linkgit:git-upload-archive[1] for more details. Defaults to
2972        `false`.
2973
2974uploadpack.hideRefs::
2975        This variable is the same as `transfer.hideRefs`, but applies
2976        only to `upload-pack` (and so affects only fetches, not pushes).
2977        An attempt to fetch a hidden ref by `git fetch` will fail.  See
2978        also `uploadpack.allowTipSHA1InWant`.
2979
2980uploadpack.allowTipSHA1InWant::
2981        When `uploadpack.hideRefs` is in effect, allow `upload-pack`
2982        to accept a fetch request that asks for an object at the tip
2983        of a hidden ref (by default, such a request is rejected).
2984        See also `uploadpack.hideRefs`.  Even if this is false, a client
2985        may be able to steal objects via the techniques described in the
2986        "SECURITY" section of the linkgit:gitnamespaces[7] man page; it's
2987        best to keep private data in a separate repository.
2988
2989uploadpack.allowReachableSHA1InWant::
2990        Allow `upload-pack` to accept a fetch request that asks for an
2991        object that is reachable from any ref tip. However, note that
2992        calculating object reachability is computationally expensive.
2993        Defaults to `false`.  Even if this is false, a client may be able
2994        to steal objects via the techniques described in the "SECURITY"
2995        section of the linkgit:gitnamespaces[7] man page; it's best to
2996        keep private data in a separate repository.
2997
2998uploadpack.allowAnySHA1InWant::
2999        Allow `upload-pack` to accept a fetch request that asks for any
3000        object at all.
3001        Defaults to `false`.
3002
3003uploadpack.keepAlive::
3004        When `upload-pack` has started `pack-objects`, there may be a
3005        quiet period while `pack-objects` prepares the pack. Normally
3006        it would output progress information, but if `--quiet` was used
3007        for the fetch, `pack-objects` will output nothing at all until
3008        the pack data begins. Some clients and networks may consider
3009        the server to be hung and give up. Setting this option instructs
3010        `upload-pack` to send an empty keepalive packet every
3011        `uploadpack.keepAlive` seconds. Setting this option to 0
3012        disables keepalive packets entirely. The default is 5 seconds.
3013
3014uploadpack.packObjectsHook::
3015        If this option is set, when `upload-pack` would run
3016        `git pack-objects` to create a packfile for a client, it will
3017        run this shell command instead.  The `pack-objects` command and
3018        arguments it _would_ have run (including the `git pack-objects`
3019        at the beginning) are appended to the shell command. The stdin
3020        and stdout of the hook are treated as if `pack-objects` itself
3021        was run. I.e., `upload-pack` will feed input intended for
3022        `pack-objects` to the hook, and expects a completed packfile on
3023        stdout.
3024+
3025Note that this configuration variable is ignored if it is seen in the
3026repository-level config (this is a safety measure against fetching from
3027untrusted repositories).
3028
3029uploadpack.allowFilter::
3030        If this option is set, `upload-pack` will support partial
3031        clone and partial fetch object filtering.
3032
3033uploadpack.allowRefInWant::
3034        If this option is set, `upload-pack` will support the `ref-in-want`
3035        feature of the protocol version 2 `fetch` command.  This feature
3036        is intended for the benefit of load-balanced servers which may
3037        not have the same view of what OIDs their refs point to due to
3038        replication delay.
3039
3040url.<base>.insteadOf::
3041        Any URL that starts with this value will be rewritten to
3042        start, instead, with <base>. In cases where some site serves a
3043        large number of repositories, and serves them with multiple
3044        access methods, and some users need to use different access
3045        methods, this feature allows people to specify any of the
3046        equivalent URLs and have Git automatically rewrite the URL to
3047        the best alternative for the particular user, even for a
3048        never-before-seen repository on the site.  When more than one
3049        insteadOf strings match a given URL, the longest match is used.
3050+
3051Note that any protocol restrictions will be applied to the rewritten
3052URL. If the rewrite changes the URL to use a custom protocol or remote
3053helper, you may need to adjust the `protocol.*.allow` config to permit
3054the request.  In particular, protocols you expect to use for submodules
3055must be set to `always` rather than the default of `user`. See the
3056description of `protocol.allow` above.
3057
3058url.<base>.pushInsteadOf::
3059        Any URL that starts with this value will not be pushed to;
3060        instead, it will be rewritten to start with <base>, and the
3061        resulting URL will be pushed to. In cases where some site serves
3062        a large number of repositories, and serves them with multiple
3063        access methods, some of which do not allow push, this feature
3064        allows people to specify a pull-only URL and have Git
3065        automatically use an appropriate URL to push, even for a
3066        never-before-seen repository on the site.  When more than one
3067        pushInsteadOf strings match a given URL, the longest match is
3068        used.  If a remote has an explicit pushurl, Git will ignore this
3069        setting for that remote.
3070
3071user.email::
3072        Your email address to be recorded in any newly created commits.
3073        Can be overridden by the `GIT_AUTHOR_EMAIL`, `GIT_COMMITTER_EMAIL`, and
3074        `EMAIL` environment variables.  See linkgit:git-commit-tree[1].
3075
3076user.name::
3077        Your full name to be recorded in any newly created commits.
3078        Can be overridden by the `GIT_AUTHOR_NAME` and `GIT_COMMITTER_NAME`
3079        environment variables.  See linkgit:git-commit-tree[1].
3080
3081user.useConfigOnly::
3082        Instruct Git to avoid trying to guess defaults for `user.email`
3083        and `user.name`, and instead retrieve the values only from the
3084        configuration. For example, if you have multiple email addresses
3085        and would like to use a different one for each repository, then
3086        with this configuration option set to `true` in the global config
3087        along with a name, Git will prompt you to set up an email before
3088        making new commits in a newly cloned repository.
3089        Defaults to `false`.
3090
3091user.signingKey::
3092        If linkgit:git-tag[1] or linkgit:git-commit[1] is not selecting the
3093        key you want it to automatically when creating a signed tag or
3094        commit, you can override the default selection with this variable.
3095        This option is passed unchanged to gpg's --local-user parameter,
3096        so you may specify a key using any method that gpg supports.
3097
3098versionsort.prereleaseSuffix (deprecated)::
3099        Deprecated alias for `versionsort.suffix`.  Ignored if
3100        `versionsort.suffix` is set.
3101
3102versionsort.suffix::
3103        Even when version sort is used in linkgit:git-tag[1], tagnames
3104        with the same base version but different suffixes are still sorted
3105        lexicographically, resulting e.g. in prerelease tags appearing
3106        after the main release (e.g. "1.0-rc1" after "1.0").  This
3107        variable can be specified to determine the sorting order of tags
3108        with different suffixes.
3109+
3110By specifying a single suffix in this variable, any tagname containing
3111that suffix will appear before the corresponding main release.  E.g. if
3112the variable is set to "-rc", then all "1.0-rcX" tags will appear before
3113"1.0".  If specified multiple times, once per suffix, then the order of
3114suffixes in the configuration will determine the sorting order of tagnames
3115with those suffixes.  E.g. if "-pre" appears before "-rc" in the
3116configuration, then all "1.0-preX" tags will be listed before any
3117"1.0-rcX" tags.  The placement of the main release tag relative to tags
3118with various suffixes can be determined by specifying the empty suffix
3119among those other suffixes.  E.g. if the suffixes "-rc", "", "-ck" and
3120"-bfs" appear in the configuration in this order, then all "v4.8-rcX" tags
3121are listed first, followed by "v4.8", then "v4.8-ckX" and finally
3122"v4.8-bfsX".
3123+
3124If more than one suffixes match the same tagname, then that tagname will
3125be sorted according to the suffix which starts at the earliest position in
3126the tagname.  If more than one different matching suffixes start at
3127that earliest position, then that tagname will be sorted according to the
3128longest of those suffixes.
3129The sorting order between different suffixes is undefined if they are
3130in multiple config files.
3131
3132web.browser::
3133        Specify a web browser that may be used by some commands.
3134        Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
3135        may use it.
3136
3137worktree.guessRemote::
3138        With `add`, if no branch argument, and neither of `-b` nor
3139        `-B` nor `--detach` are given, the command defaults to
3140        creating a new branch from HEAD.  If `worktree.guessRemote` is
3141        set to true, `worktree add` tries to find a remote-tracking
3142        branch whose name uniquely matches the new branch name.  If
3143        such a branch exists, it is checked out and set as "upstream"
3144        for the new branch.  If no such match can be found, it falls
3145        back to creating a new branch from the current HEAD.
