   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.
  18
  19Syntax
  20~~~~~~
  21
  22The syntax is fairly flexible and permissive; whitespaces are mostly
  23ignored.  The '#' and ';' characters begin comments to the end of line,
  24blank lines are ignored.
  25
  26The file consists of sections and variables.  A section begins with
  27the name of the section in square brackets and continues until the next
  28section begins.  Section names are not case sensitive.  Only alphanumeric
  29characters, `-` and `.` are allowed in section names.  Each variable
  30must belong to some section, which means that there must be a section
  31header before the first setting of a variable.
  32
  33Sections can be further divided into subsections.  To begin a subsection
  34put its name in double quotes, separated by space from the section name,
  35in the section header, like in the example below:
  36
  37--------
  38        [section "subsection"]
  39
  40--------
  41
  42Subsection names are case sensitive and can contain any characters except
  43newline (doublequote `"` and backslash have to be escaped as `\"` and `\\`,
  44respectively).  Section headers cannot span multiple
  45lines.  Variables may belong directly to a section or to a given subsection.
  46You can have `[section]` if you have `[section "subsection"]`, but you
  47don't need to.
  48
  49There is also a deprecated `[section.subsection]` syntax. With this
  50syntax, the subsection name is converted to lower-case and is also
  51compared case sensitively. These subsection names follow the same
  52restrictions as section names.
  53
  54All the other lines (and the remainder of the line after the section
  55header) are recognized as setting variables, in the form
  56'name = value'.  If there is no equal sign on the line, the entire line
  57is taken as 'name' and the variable is recognized as boolean "true".
  58The variable names are case-insensitive, allow only alphanumeric characters
  59and `-`, and must start with an alphabetic character.  There can be more
  60than one value for a given variable; we say then that the variable is
  61multivalued.
  62
  63Leading and trailing whitespace in a variable value is discarded.
  64Internal whitespace within a variable value is retained verbatim.
  65
  66The values following the equals sign in variable assign are all either
  67a string, an integer, or a boolean.  Boolean values may be given as yes/no,
  681/0, true/false or on/off.  Case is not significant in boolean values, when
  69converting value to the canonical form using '--bool' type specifier;
  70'git config' will ensure that the output is "true" or "false".
  71
  72String values may be entirely or partially enclosed in double quotes.
  73You need to enclose variable values in double quotes if you want to
  74preserve leading or trailing whitespace, or if the variable value contains
  75comment characters (i.e. it contains '#' or ';').
  76Double quote `"` and backslash `\` characters in variable values must
  77be escaped: use `\"` for `"` and `\\` for `\`.
  78
  79The following escape sequences (beside `\"` and `\\`) are recognized:
  80`\n` for newline character (NL), `\t` for horizontal tabulation (HT, TAB)
  81and `\b` for backspace (BS).  No other char escape sequence, nor octal
  82char sequences are valid.
  83
  84Variable values ending in a `\` are continued on the next line in the
  85customary UNIX fashion.
  86
  87Some variables may require a special value format.
  88
  89Includes
  90~~~~~~~~
  91
  92You can include one config file from another by setting the special
  93`include.path` variable to the name of the file to be included. The
  94included file is expanded immediately, as if its contents had been
  95found at the location of the include directive. If the value of the
  96`include.path` variable is a relative path, the path is considered to be
  97relative to the configuration file in which the include directive was
  98found. The value of `include.path` is subject to tilde expansion: `~/`
  99is expanded to the value of `$HOME`, and `~user/` to the specified
 100user's home directory. See below for examples.
 101

 131
 132Note that this list is non-comprehensive and not necessarily complete.
 133For command-specific variables, you will find a more detailed description
 134in the appropriate manual page. You will find a description of non-core
 135porcelain configuration variables in the respective porcelain documentation.
 136
 137advice.*::
 138        These variables control various optional help messages designed to
 139        aid new users. All 'advice.*' variables default to 'true', and you
 140        can tell Git that you do not need help by setting these to 'false':
 141+
 142--
 143        pushUpdateRejected::
 144                Set this variable to 'false' if you want to disable
 145                'pushNonFFCurrent', 'pushNonFFDefault',
 146                'pushNonFFMatching', 'pushAlreadyExists',
 147                'pushFetchFirst', and 'pushNeedsForce'
 148                simultaneously.
 149        pushNonFFCurrent::
 150                Advice shown when linkgit:git-push[1] fails due to a
 151                non-fast-forward update to the current branch.
 152        pushNonFFDefault::
 153                Advice to set 'push.default' to 'upstream' or 'current'
 154                when you ran linkgit:git-push[1] and pushed 'matching
 155                refs' by default (i.e. you did not provide an explicit
 156                refspec, and no 'push.default' configuration was set)
 157                and it resulted in a non-fast-forward error.
 158        pushNonFFMatching::
 159                Advice shown when you ran linkgit:git-push[1] and pushed
 160                'matching refs' explicitly (i.e. you used ':', or
 161                specified a refspec that isn't your current branch) and
 162                it resulted in a non-fast-forward error.
 163        pushAlreadyExists::
 164                Shown when linkgit:git-push[1] rejects an update that
 165                does not qualify for fast-forwarding (e.g., a tag.)
 166        pushFetchFirst::
 167                Shown when linkgit:git-push[1] rejects an update that
 168                tries to overwrite a remote ref that points at an
 169                object we do not have.
 170        pushNeedsForce::
 171                Shown when linkgit:git-push[1] rejects an update that
 172                tries to overwrite a remote ref that points at an
 173                object that is not a committish, or make the remote
 174                ref point at an object that is not a committish.
 175        statusHints::
 176                Show directions on how to proceed from the current
 177                state in the output of linkgit:git-status[1], in
 178                the template shown when writing commit messages in
 179                linkgit:git-commit[1], and in the help message shown
 180                by linkgit:git-checkout[1] when switching branch.
 181        statusUoption::
 182                Advise to consider using the `-u` option to linkgit:git-status[1]
 183                when the command takes more than 2 seconds to enumerate untracked
 184                files.
 185        commitBeforeMerge::
 186                Advice shown when linkgit:git-merge[1] refuses to
 187                merge to avoid overwriting local changes.
 188        resolveConflict::
 189                Advice shown by various commands when conflicts
 190                prevent the operation from being performed.
 191        implicitIdentity::
 192                Advice on how to set your identity configuration when
 193                your information is guessed from the system username and
 194                domain name.
 195        detachedHead::
 196                Advice shown when you used linkgit:git-checkout[1] to
 197                move to the detach HEAD state, to instruct how to create
 198                a local branch after the fact.
 199        amWorkDir::
 200                Advice that shows the location of the patch file when
 201                linkgit:git-am[1] fails to apply it.
 202--
 203
 204core.fileMode::
 205        If false, the executable bit differences between the index and
 206        the working tree are ignored; useful on broken filesystems like FAT.
 207        See linkgit:git-update-index[1].
 208+
 209The default is true, except linkgit:git-clone[1] or linkgit:git-init[1]
 210will probe and set core.fileMode false if appropriate when the
 211repository is created.
 212
 213core.ignoreCygwinFSTricks::
 214        This option is only used by Cygwin implementation of Git. If false,
 215        the Cygwin stat() and lstat() functions are used. This may be useful
 216        if your repository consists of a few separate directories joined in
 217        one hierarchy using Cygwin mount. If true, Git uses native Win32 API
 218        whenever it is possible and falls back to Cygwin functions only to
 219        handle symbol links. The native mode is more than twice faster than
 220        normal Cygwin l/stat() functions. True by default, unless core.filemode
 221        is true, in which case ignoreCygwinFSTricks is ignored as Cygwin's
 222        POSIX emulation is required to support core.filemode.
 223
 224core.ignorecase::
 225        If true, this option enables various workarounds to enable
 226        Git to work better on filesystems that are not case sensitive,
 227        like FAT. For example, if a directory listing finds
 228        "makefile" when Git expects "Makefile", Git will assume
 229        it is really the same file, and continue to remember it as
 230        "Makefile".
 231+
 232The default is false, except linkgit:git-clone[1] or linkgit:git-init[1]
 233will probe and set core.ignorecase true if appropriate when the repository
 234is created.
 235
 236core.precomposeunicode::
 237        This option is only used by Mac OS implementation of Git.
 238        When core.precomposeunicode=true, Git reverts the unicode decomposition
 239        of filenames done by Mac OS. This is useful when sharing a repository
 240        between Mac OS and Linux or Windows.
 241        (Git for Windows 1.7.10 or higher is needed, or Git under cygwin 1.7).
 242        When false, file names are handled fully transparent by Git,
 243        which is backward compatible with older versions of Git.
 244
 245core.trustctime::
 246        If false, the ctime differences between the index and the
 247        working tree are ignored; useful when the inode change time
 248        is regularly modified by something outside Git (file system
 249        crawlers and some backup systems).
 250        See linkgit:git-update-index[1]. True by default.
 251
 252core.checkstat::
 253        Determines which stat fields to match between the index
 254        and work tree. The user can set this to 'default' or
 255        'minimal'. Default (or explicitly 'default'), is to check
 256        all fields, including the sub-second part of mtime and ctime.
 257
 258core.quotepath::
 259        The commands that output paths (e.g. 'ls-files',
 260        'diff'), when not given the `-z` option, will quote
 261        "unusual" characters in the pathname by enclosing the
 262        pathname in a double-quote pair and with backslashes the
 263        same way strings in C source code are quoted.  If this
 264        variable is set to false, the bytes higher than 0x80 are
 265        not quoted but output as verbatim.  Note that double
 266        quote, backslash and control characters are always
 267        quoted without `-z` regardless of the setting of this
 268        variable.
 269
 270core.eol::
 271        Sets the line ending type to use in the working directory for
 272        files that have the `text` property set.  Alternatives are
 273        'lf', 'crlf' and 'native', which uses the platform's native
 274        line ending.  The default value is `native`.  See
 275        linkgit:gitattributes[5] for more information on end-of-line
 276        conversion.
 277
 278core.safecrlf::
 279        If true, makes Git check if converting `CRLF` is reversible when
 280        end-of-line conversion is active.  Git will verify if a command
 281        modifies a file in the work tree either directly or indirectly.
 282        For example, committing a file followed by checking out the
 283        same file should yield the original file in the work tree.  If
 284        this is not the case for the current setting of
 285        `core.autocrlf`, Git will reject the file.  The variable can
 286        be set to "warn", in which case Git will only warn about an
 287        irreversible conversion but continue the operation.
 288+
 289CRLF conversion bears a slight chance of corrupting data.
 290When it is enabled, Git will convert CRLF to LF during commit and LF to
 291CRLF during checkout.  A file that contains a mixture of LF and
 292CRLF before the commit cannot be recreated by Git.  For text
 293files this is the right thing to do: it corrects line endings
 294such that we have only LF line endings in the repository.
 295But for binary files that are accidentally classified as text the
 296conversion can corrupt data.
 297+
 298If you recognize such corruption early you can easily fix it by
 299setting the conversion type explicitly in .gitattributes.  Right
 300after committing you still have the original file in your work
 301tree and this file is not yet corrupted.  You can explicitly tell
 302Git that this file is binary and Git will handle the file
 303appropriately.
 304+
 305Unfortunately, the desired effect of cleaning up text files with
 306mixed line endings and the undesired effect of corrupting binary
 307files cannot be distinguished.  In both cases CRLFs are removed
 308in an irreversible way.  For text files this is the right thing
 309to do because CRLFs are line endings, while for binary files
 310converting CRLFs corrupts data.
 311+
 312Note, this safety check does not mean that a checkout will generate a
 313file identical to the original file for a different setting of
 314`core.eol` and `core.autocrlf`, but only for the current one.  For
 315example, a text file with `LF` would be accepted with `core.eol=lf`
 316and could later be checked out with `core.eol=crlf`, in which case the
 317resulting file would contain `CRLF`, although the original file
 318contained `LF`.  However, in both work trees the line endings would be
 319consistent, that is either all `LF` or all `CRLF`, but never mixed.  A
 320file with mixed line endings would be reported by the `core.safecrlf`
 321mechanism.
 322
 323core.autocrlf::
 324        Setting this variable to "true" is almost the same as setting
 325        the `text` attribute to "auto" on all files except that text
 326        files are not guaranteed to be normalized: files that contain
 327        `CRLF` in the repository will not be touched.  Use this
 328        setting if you want to have `CRLF` line endings in your
 329        working directory even though the repository does not have
 330        normalized line endings.  This variable can be set to 'input',
 331        in which case no output conversion is performed.
 332
 333core.symlinks::
 334        If false, symbolic links are checked out as small plain files that
 335        contain the link text. linkgit:git-update-index[1] and
 336        linkgit:git-add[1] will not change the recorded type to regular
 337        file. Useful on filesystems like FAT that do not support
 338        symbolic links.
 339+
 340The default is true, except linkgit:git-clone[1] or linkgit:git-init[1]
 341will probe and set core.symlinks false if appropriate when the repository
 342is created.
 343
 344core.gitProxy::
 345        A "proxy command" to execute (as 'command host port') instead
 346        of establishing direct connection to the remote server when
 347        using the Git protocol for fetching. If the variable value is
 348        in the "COMMAND for DOMAIN" format, the command is applied only
 349        on hostnames ending with the specified domain string. This variable
 350        may be set multiple times and is matched in the given order;
 351        the first match wins.
 352+
 353Can be overridden by the 'GIT_PROXY_COMMAND' environment variable
 354(which always applies universally, without the special "for"
 355handling).
 356+
 357The special string `none` can be used as the proxy command to
 358specify that no proxy be used for a given domain pattern.
 359This is useful for excluding servers inside a firewall from
 360proxy use, while defaulting to a common proxy for external domains.
 361
 362core.ignoreStat::
 363        If true, commands which modify both the working tree and the index
 364        will mark the updated paths with the "assume unchanged" bit in the
 365        index. These marked files are then assumed to stay unchanged in the
 366        working tree, until you mark them otherwise manually - Git will not
 367        detect the file changes by lstat() calls. This is useful on systems
 368        where those are very slow, such as Microsoft Windows.
 369        See linkgit:git-update-index[1].
 370        False by default.
 371
 372core.preferSymlinkRefs::
 373        Instead of the default "symref" format for HEAD
 374        and other symbolic reference files, use symbolic links.
 375        This is sometimes needed to work with old scripts that
 376        expect HEAD to be a symbolic link.
 377
 378core.bare::
 379        If true this repository is assumed to be 'bare' and has no
 380        working directory associated with it.  If this is the case a
 381        number of commands that require a working directory will be
 382        disabled, such as linkgit:git-add[1] or linkgit:git-merge[1].
 383+
 384This setting is automatically guessed by linkgit:git-clone[1] or
 385linkgit:git-init[1] when the repository was created.  By default a
 386repository that ends in "/.git" is assumed to be not bare (bare =
 387false), while all other repositories are assumed to be bare (bare
 388= true).
 389
 390core.worktree::
 391        Set the path to the root of the working tree.
 392        This can be overridden by the GIT_WORK_TREE environment
 393        variable and the '--work-tree' command line option.
 394        The value can be an absolute path or relative to the path to
 395        the .git directory, which is either specified by --git-dir
 396        or GIT_DIR, or automatically discovered.
 397        If --git-dir or GIT_DIR is specified but none of
 398        --work-tree, GIT_WORK_TREE and core.worktree is specified,
 399        the current working directory is regarded as the top level
 400        of your working tree.
 401+
 402Note that this variable is honored even when set in a configuration
 403file in a ".git" subdirectory of a directory and its value differs
 404from the latter directory (e.g. "/path/to/.git/config" has
 405core.worktree set to "/different/path"), which is most likely a
 406misconfiguration.  Running Git commands in the "/path/to" directory will
 407still use "/different/path" as the root of the work tree and can cause
 408confusion unless you know what you are doing (e.g. you are creating a
 409read-only snapshot of the same index to a location different from the
 410repository's usual working tree).
 411
 412core.logAllRefUpdates::
 413        Enable the reflog. Updates to a ref <ref> is logged to the file
 414        "$GIT_DIR/logs/<ref>", by appending the new and old
 415        SHA-1, the date/time and the reason of the update, but
 416        only when the file exists.  If this configuration
 417        variable is set to true, missing "$GIT_DIR/logs/<ref>"
 418        file is automatically created for branch heads (i.e. under
 419        refs/heads/), remote refs (i.e. under refs/remotes/),
 420        note refs (i.e. under refs/notes/), and the symbolic ref HEAD.
 421+
 422This information can be used to determine what commit
 423was the tip of a branch "2 days ago".
 424+
 425This value is true by default in a repository that has
 426a working directory associated with it, and false by
 427default in a bare repository.
 428
 429core.repositoryFormatVersion::
 430        Internal variable identifying the repository format and layout
 431        version.
 432
 433core.sharedRepository::
 434        When 'group' (or 'true'), the repository is made shareable between
 435        several users in a group (making sure all the files and objects are
 436        group-writable). When 'all' (or 'world' or 'everybody'), the
 437        repository will be readable by all users, additionally to being
 438        group-shareable. When 'umask' (or 'false'), Git will use permissions
 439        reported by umask(2). When '0xxx', where '0xxx' is an octal number,
 440        files in the repository will have this mode value. '0xxx' will override
 441        user's umask value (whereas the other options will only override
 442        requested parts of the user's umask value). Examples: '0660' will make
 443        the repo read/write-able for the owner and group, but inaccessible to
 444        others (equivalent to 'group' unless umask is e.g. '0022'). '0640' is a
 445        repository that is group-readable but not group-writable.
 446        See linkgit:git-init[1]. False by default.
 447
 448core.warnAmbiguousRefs::
 449        If true, Git will warn you if the ref name you passed it is ambiguous
 450        and might match multiple refs in the repository. True by default.
 451
 452core.compression::
 453        An integer -1..9, indicating a default compression level.
 454        -1 is the zlib default. 0 means no compression,
 455        and 1..9 are various speed/size tradeoffs, 9 being slowest.
 456        If set, this provides a default to other compression variables,
 457        such as 'core.loosecompression' and 'pack.compression'.
 458
 459core.loosecompression::
 460        An integer -1..9, indicating the compression level for objects that
 461        are not in a pack file. -1 is the zlib default. 0 means no
 462        compression, and 1..9 are various speed/size tradeoffs, 9 being
 463        slowest.  If not set,  defaults to core.compression.  If that is
 464        not set,  defaults to 1 (best speed).
 465
 466core.packedGitWindowSize::
 467        Number of bytes of a pack file to map into memory in a
 468        single mapping operation.  Larger window sizes may allow
 469        your system to process a smaller number of large pack files
 470        more quickly.  Smaller window sizes will negatively affect
 471        performance due to increased calls to the operating system's
 472        memory manager, but may improve performance when accessing
 473        a large number of large pack files.
 474+
 475Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
 476MiB on 32 bit platforms and 1 GiB on 64 bit platforms.  This should
 477be reasonable for all users/operating systems.  You probably do
 478not need to adjust this value.
 479+
 480Common unit suffixes of 'k', 'm', or 'g' are supported.
 481
 482core.packedGitLimit::
 483        Maximum number of bytes to map simultaneously into memory
 484        from pack files.  If Git needs to access more than this many
 485        bytes at once to complete an operation it will unmap existing
 486        regions to reclaim virtual address space within the process.
 487+
 488Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms.
 489This should be reasonable for all users/operating systems, except on
 490the largest projects.  You probably do not need to adjust this value.
 491+
 492Common unit suffixes of 'k', 'm', or 'g' are supported.
 493
 494core.deltaBaseCacheLimit::
 495        Maximum number of bytes to reserve for caching base objects
 496        that may be referenced by multiple deltified objects.  By storing the
 497        entire decompressed base objects in a cache Git is able
 498        to avoid unpacking and decompressing frequently used base
 499        objects multiple times.
 500+
 501Default is 16 MiB on all platforms.  This should be reasonable
 502for all users/operating systems, except on the largest projects.
 503You probably do not need to adjust this value.
 504+
 505Common unit suffixes of 'k', 'm', or 'g' are supported.
 506
 507core.bigFileThreshold::
 508        Files larger than this size are stored deflated, without
 509        attempting delta compression.  Storing large files without
 510        delta compression avoids excessive memory usage, at the
 511        slight expense of increased disk usage.
 512+
 513Default is 512 MiB on all platforms.  This should be reasonable
 514for most projects as source code and other text files can still
 515be delta compressed, but larger binary media files won't be.
 516+
 517Common unit suffixes of 'k', 'm', or 'g' are supported.
 518
 519core.excludesfile::
 520        In addition to '.gitignore' (per-directory) and
 521        '.git/info/exclude', Git looks into this file for patterns
 522        of files which are not meant to be tracked.  "`~/`" is expanded
 523        to the value of `$HOME` and "`~user/`" to the specified user's
 524        home directory. Its default value is $XDG_CONFIG_HOME/git/ignore.
 525        If $XDG_CONFIG_HOME is either not set or empty, $HOME/.config/git/ignore
 526        is used instead. See linkgit:gitignore[5].
 527
 528core.askpass::
 529        Some commands (e.g. svn and http interfaces) that interactively
 530        ask for a password can be told to use an external program given
 531        via the value of this variable. Can be overridden by the 'GIT_ASKPASS'
 532        environment variable. If not set, fall back to the value of the
 533        'SSH_ASKPASS' environment variable or, failing that, a simple password
 534        prompt. The external program shall be given a suitable prompt as
 535        command line argument and write the password on its STDOUT.
 536
 537core.attributesfile::
 538        In addition to '.gitattributes' (per-directory) and
 539        '.git/info/attributes', Git looks into this file for attributes
 540        (see linkgit:gitattributes[5]). Path expansions are made the same
 541        way as for `core.excludesfile`. Its default value is
 542        $XDG_CONFIG_HOME/git/attributes. If $XDG_CONFIG_HOME is either not
 543        set or empty, $HOME/.config/git/attributes is used instead.
 544
 545core.editor::
 546        Commands such as `commit` and `tag` that lets you edit
 547        messages by launching an editor uses the value of this
 548        variable when it is set, and the environment variable
 549        `GIT_EDITOR` is not set.  See linkgit:git-var[1].
 550
 551core.commentchar::
 552        Commands such as `commit` and `tag` that lets you edit
 553        messages consider a line that begins with this character
 554        commented, and removes them after the editor returns
 555        (default '#').
 556
 557sequence.editor::
 558        Text editor used by `git rebase -i` for editing the rebase instruction file.
 559        The value is meant to be interpreted by the shell when it is used.
 560        It can be overridden by the `GIT_SEQUENCE_EDITOR` environment variable.
 561        When not configured the default commit message editor is used instead.
 562
 563core.pager::
 564        The command that Git will use to paginate output.  Can
 565        be overridden with the `GIT_PAGER` environment
 566        variable.  Note that Git sets the `LESS` environment
 567        variable to `FRSX` if it is unset when it runs the
 568        pager.  One can change these settings by setting the
 569        `LESS` variable to some other value.  Alternately,
 570        these settings can be overridden on a project or
 571        global basis by setting the `core.pager` option.
 572        Setting `core.pager` has no effect on the `LESS`
 573        environment variable behaviour above, so if you want
 574        to override Git's default settings this way, you need
 575        to be explicit.  For example, to disable the S option
 576        in a backward compatible manner, set `core.pager`
 577        to `less -+S`.  This will be passed to the shell by
 578        Git, which will translate the final command to
 579        `LESS=FRSX less -+S`.
 580
 581core.whitespace::
 582        A comma separated list of common whitespace problems to
 583        notice.  'git diff' will use `color.diff.whitespace` to
 584        highlight them, and 'git apply --whitespace=error' will
 585        consider them as errors.  You can prefix `-` to disable
 586        any of them (e.g. `-trailing-space`):
 587+
 588* `blank-at-eol` treats trailing whitespaces at the end of the line
 589  as an error (enabled by default).
 590* `space-before-tab` treats a space character that appears immediately
 591  before a tab character in the initial indent part of the line as an
 592  error (enabled by default).
 593* `indent-with-non-tab` treats a line that is indented with space
 594  characters instead of the equivalent tabs as an error (not enabled by
 595  default).
 596* `tab-in-indent` treats a tab character in the initial indent part of
 597  the line as an error (not enabled by default).
 598* `blank-at-eof` treats blank lines added at the end of file as an error
 599  (enabled by default).
 600* `trailing-space` is a short-hand to cover both `blank-at-eol` and
 601  `blank-at-eof`.
 602* `cr-at-eol` treats a carriage-return at the end of line as
 603  part of the line terminator, i.e. with it, `trailing-space`
 604  does not trigger if the character before such a carriage-return
 605  is not a whitespace (not enabled by default).
 606* `tabwidth=<n>` tells how many character positions a tab occupies; this
 607  is relevant for `indent-with-non-tab` and when Git fixes `tab-in-indent`
 608  errors. The default tab width is 8. Allowed values are 1 to 63.
 609
 610core.fsyncobjectfiles::
 611        This boolean will enable 'fsync()' when writing object files.
 612+
 613This is a total waste of time and effort on a filesystem that orders
 614data writes properly, but can be useful for filesystems that do not use
 615journalling (traditional UNIX filesystems) or that only journal metadata
 616and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback").
 617
 618core.preloadindex::
 619        Enable parallel index preload for operations like 'git diff'
 620+
 621This can speed up operations like 'git diff' and 'git status' especially
 622on filesystems like NFS that have weak caching semantics and thus
 623relatively high IO latencies.  With this set to 'true', Git will do the
 624index comparison to the filesystem data in parallel, allowing
 625overlapping IO's.
 626
 627core.createObject::
 628        You can set this to 'link', in which case a hardlink followed by
 629        a delete of the source are used to make sure that object creation
 630        will not overwrite existing objects.
 631+
 632On some file system/operating system combinations, this is unreliable.
 633Set this config setting to 'rename' there; However, This will remove the
 634check that makes sure that existing object files will not get overwritten.
 635
 636core.notesRef::
 637        When showing commit messages, also show notes which are stored in
 638        the given ref.  The ref must be fully qualified.  If the given
 639        ref does not exist, it is not an error but means that no
 640        notes should be printed.
 641+
 642This setting defaults to "refs/notes/commits", and it can be overridden by
 643the 'GIT_NOTES_REF' environment variable.  See linkgit:git-notes[1].
 644
 645core.sparseCheckout::
 646        Enable "sparse checkout" feature. See section "Sparse checkout" in
 647        linkgit:git-read-tree[1] for more information.
 648
 649core.abbrev::
 650        Set the length object names are abbreviated to.  If unspecified,
 651        many commands abbreviate to 7 hexdigits, which may not be enough
 652        for abbreviated object names to stay unique for sufficiently long
 653        time.
 654
 655add.ignore-errors::
 656add.ignoreErrors::
 657        Tells 'git add' to continue adding files when some files cannot be
 658        added due to indexing errors. Equivalent to the '--ignore-errors'
 659        option of linkgit:git-add[1].  Older versions of Git accept only
 660        `add.ignore-errors`, which does not follow the usual naming
 661        convention for configuration variables.  Newer versions of Git
 662        honor `add.ignoreErrors` as well.
 663
 664alias.*::
 665        Command aliases for the linkgit:git[1] command wrapper - e.g.
 666        after defining "alias.last = cat-file commit HEAD", the invocation
 667        "git last" is equivalent to "git cat-file commit HEAD". To avoid
 668        confusion and troubles with script usage, aliases that
 669        hide existing Git commands are ignored. Arguments are split by
 670        spaces, the usual shell quoting and escaping is supported.
 671        quote pair and a backslash can be used to quote them.
 672+
 673If the alias expansion is prefixed with an exclamation point,
 674it will be treated as a shell command.  For example, defining
 675"alias.new = !gitk --all --not ORIG_HEAD", the invocation
 676"git new" is equivalent to running the shell command
 677"gitk --all --not ORIG_HEAD".  Note that shell commands will be
 678executed from the top-level directory of a repository, which may
 679not necessarily be the current directory.
 680'GIT_PREFIX' is set as returned by running 'git rev-parse --show-prefix'
 681from the original current directory. See linkgit:git-rev-parse[1].
 682
 683am.keepcr::
 684        If true, git-am will call git-mailsplit for patches in mbox format
 685        with parameter '--keep-cr'. In this case git-mailsplit will
 686        not remove `\r` from lines ending with `\r\n`. Can be overridden
 687        by giving '--no-keep-cr' from the command line.
 688        See linkgit:git-am[1], linkgit:git-mailsplit[1].
 689
 690apply.ignorewhitespace::
 691        When set to 'change', tells 'git apply' to ignore changes in
 692        whitespace, in the same way as the '--ignore-space-change'
 693        option.
 694        When set to one of: no, none, never, false tells 'git apply' to
 695        respect all whitespace differences.
 696        See linkgit:git-apply[1].
 697
 698apply.whitespace::
 699        Tells 'git apply' how to handle whitespaces, in the same way
 700        as the '--whitespace' option. See linkgit:git-apply[1].
 701
 702branch.autosetupmerge::
 703        Tells 'git branch' and 'git checkout' to set up new branches
 704        so that linkgit:git-pull[1] will appropriately merge from the
 705        starting point branch. Note that even if this option is not set,
 706        this behavior can be chosen per-branch using the `--track`
 707        and `--no-track` options. The valid settings are: `false` -- no
 708        automatic setup is done; `true` -- automatic setup is done when the
 709        starting point is a remote-tracking branch; `always` --
 710        automatic setup is done when the starting point is either a
 711        local branch or remote-tracking
 712        branch. This option defaults to true.
 713
 714branch.autosetuprebase::
 715        When a new branch is created with 'git branch' or 'git checkout'
 716        that tracks another branch, this variable tells Git to set
 717        up pull to rebase instead of merge (see "branch.<name>.rebase").
 718        When `never`, rebase is never automatically set to true.
 719        When `local`, rebase is set to true for tracked branches of
 720        other local branches.
 721        When `remote`, rebase is set to true for tracked branches of
 722        remote-tracking branches.
 723        When `always`, rebase will be set to true for all tracking
 724        branches.
 725        See "branch.autosetupmerge" for details on how to set up a
 726        branch to track another branch.
 727        This option defaults to never.
 728
 729branch.<name>.remote::
 730        When on branch <name>, it tells 'git fetch' and 'git push'
 731        which remote to fetch from/push to.  The remote to push to
 732        may be overridden with `remote.pushdefault` (for all branches).
 733        The remote to push to, for the current branch, may be further
 734        overridden by `branch.<name>.pushremote`.  If no remote is
 735        configured, or if you are not on any branch, it defaults to
 736        `origin` for fetching and `remote.pushdefault` for pushing.
 737
 738branch.<name>.pushremote::
 739        When on branch <name>, it overrides `branch.<name>.remote` for
 740        pushing.  It also overrides `remote.pushdefault` for pushing
 741        from branch <name>.  When you pull from one place (e.g. your
 742        upstream) and push to another place (e.g. your own publishing
 743        repository), you would want to set `remote.pushdefault` to
 744        specify the remote to push to for all branches, and use this
 745        option to override it for a specific branch.
 746
 747branch.<name>.merge::
 748        Defines, together with branch.<name>.remote, the upstream branch
 749        for the given branch. It tells 'git fetch'/'git pull'/'git rebase' which
 750        branch to merge and can also affect 'git push' (see push.default).
 751        When in branch <name>, it tells 'git fetch' the default
 752        refspec to be marked for merging in FETCH_HEAD. The value is
 753        handled like the remote part of a refspec, and must match a
 754        ref which is fetched from the remote given by
 755        "branch.<name>.remote".
 756        The merge information is used by 'git pull' (which at first calls
 757        'git fetch') to lookup the default branch for merging. Without
 758        this option, 'git pull' defaults to merge the first refspec fetched.
 759        Specify multiple values to get an octopus merge.
 760        If you wish to setup 'git pull' so that it merges into <name> from
 761        another branch in the local repository, you can point
 762        branch.<name>.merge to the desired branch, and use the special setting
 763        `.` (a period) for branch.<name>.remote.
 764
 765branch.<name>.mergeoptions::
 766        Sets default options for merging into branch <name>. The syntax and
 767        supported options are the same as those of linkgit:git-merge[1], but
 768        option values containing whitespace characters are currently not
 769        supported.
 770
 771branch.<name>.rebase::
 772        When true, rebase the branch <name> on top of the fetched branch,
 773        instead of merging the default branch from the default remote when
 774        "git pull" is run. See "pull.rebase" for doing this in a non
 775        branch-specific manner.
 776+
 777*NOTE*: this is a possibly dangerous operation; do *not* use
 778it unless you understand the implications (see linkgit:git-rebase[1]
 779for details).
 780
 781branch.<name>.description::
 782        Branch description, can be edited with
 783        `git branch --edit-description`. Branch description is
 784        automatically added in the format-patch cover letter or
 785        request-pull summary.
 786
 787browser.<tool>.cmd::
 788        Specify the command to invoke the specified browser. The
 789        specified command is evaluated in shell with the URLs passed
 790        as arguments. (See linkgit:git-web{litdd}browse[1].)
 791
 792browser.<tool>.path::
 793        Override the path for the given tool that may be used to
 794        browse HTML help (see '-w' option in linkgit:git-help[1]) or a
 795        working repository in gitweb (see linkgit:git-instaweb[1]).
 796
 797clean.requireForce::
 798        A boolean to make git-clean do nothing unless given -f
 799        or -n.   Defaults to true.
 800
 801color.branch::
 802        A boolean to enable/disable color in the output of
 803        linkgit:git-branch[1]. May be set to `always`,
 804        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 805        only when the output is to a terminal. Defaults to false.
 806
 807color.branch.<slot>::
 808        Use customized color for branch coloration. `<slot>` is one of
 809        `current` (the current branch), `local` (a local branch),
 810        `remote` (a remote-tracking branch in refs/remotes/),
 811        `upstream` (upstream tracking branch), `plain` (other
 812        refs).
 813+
 814The value for these configuration variables is a list of colors (at most
 815two) and attributes (at most one), separated by spaces.  The colors
 816accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`,
 817`magenta`, `cyan` and `white`; the attributes are `bold`, `dim`, `ul`,
 818`blink` and `reverse`.  The first color given is the foreground; the
 819second is the background.  The position of the attribute, if any,
 820doesn't matter.
 821
 822color.diff::
 823        Whether to use ANSI escape sequences to add color to patches.
 824        If this is set to `always`, linkgit:git-diff[1],
 825        linkgit:git-log[1], and linkgit:git-show[1] will use color
 826        for all patches.  If it is set to `true` or `auto`, those
 827        commands will only use color when output is to the terminal.
 828        Defaults to false.
 829+
 830This does not affect linkgit:git-format-patch[1] nor the
 831'git-diff-{asterisk}' plumbing commands.  Can be overridden on the
 832command line with the `--color[=<when>]` option.
 833
 834color.diff.<slot>::
 835        Use customized color for diff colorization.  `<slot>` specifies
 836        which part of the patch to use the specified color, and is one
 837        of `plain` (context text), `meta` (metainformation), `frag`
 838        (hunk header), 'func' (function in hunk header), `old` (removed lines),
 839        `new` (added lines), `commit` (commit headers), or `whitespace`
 840        (highlighting whitespace errors). The values of these variables may be
 841        specified as in color.branch.<slot>.
 842
 843color.decorate.<slot>::
 844        Use customized color for 'git log --decorate' output.  `<slot>` is one
 845        of `branch`, `remoteBranch`, `tag`, `stash` or `HEAD` for local
 846        branches, remote-tracking branches, tags, stash and HEAD, respectively.
 847
 848color.grep::
 849        When set to `always`, always highlight matches.  When `false` (or
 850        `never`), never.  When set to `true` or `auto`, use color only
 851        when the output is written to the terminal.  Defaults to `false`.
 852
 853color.grep.<slot>::
 854        Use customized color for grep colorization.  `<slot>` specifies which
 855        part of the line to use the specified color, and is one of
 856+
 857--
 858`context`;;
 859        non-matching text in context lines (when using `-A`, `-B`, or `-C`)
 860`filename`;;
 861        filename prefix (when not using `-h`)
 862`function`;;
 863        function name lines (when using `-p`)
 864`linenumber`;;
 865        line number prefix (when using `-n`)
 866`match`;;
 867        matching text
 868`selected`;;
 869        non-matching text in selected lines
 870`separator`;;
 871        separators between fields on a line (`:`, `-`, and `=`)
 872        and between hunks (`--`)
 873--
 874+
 875The values of these variables may be specified as in color.branch.<slot>.
 876
 877color.interactive::
 878        When set to `always`, always use colors for interactive prompts
 879        and displays (such as those used by "git-add --interactive").
 880        When false (or `never`), never.  When set to `true` or `auto`, use
 881        colors only when the output is to the terminal. Defaults to false.
 882
 883color.interactive.<slot>::
 884        Use customized color for 'git add --interactive'
 885        output. `<slot>` may be `prompt`, `header`, `help` or `error`, for
 886        four distinct types of normal output from interactive
 887        commands.  The values of these variables may be specified as
 888        in color.branch.<slot>.
 889
 890color.pager::
 891        A boolean to enable/disable colored output when the pager is in
 892        use (default is true).
 893
 894color.showbranch::
 895        A boolean to enable/disable color in the output of
 896        linkgit:git-show-branch[1]. May be set to `always`,
 897        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 898        only when the output is to a terminal. Defaults to false.
 899
 900color.status::
 901        A boolean to enable/disable color in the output of
 902        linkgit:git-status[1]. May be set to `always`,
 903        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 904        only when the output is to a terminal. Defaults to false.
 905
 906color.status.<slot>::
 907        Use customized color for status colorization. `<slot>` is
 908        one of `header` (the header text of the status message),
 909        `added` or `updated` (files which are added but not committed),
 910        `changed` (files which are changed but not added in the index),
 911        `untracked` (files which are not tracked by Git),
 912        `branch` (the current branch), or
 913        `nobranch` (the color the 'no branch' warning is shown in, defaulting
 914        to red). The values of these variables may be specified as in
 915        color.branch.<slot>.
 916
 917color.ui::
 918        This variable determines the default value for variables such
 919        as `color.diff` and `color.grep` that control the use of color
 920        per command family. Its scope will expand as more commands learn
 921        configuration to set a default for the `--color` option.  Set it
 922        to `false` or `never` if you prefer Git commands not to use
 923        color unless enabled explicitly with some other configuration
 924        or the `--color` option. Set it to `always` if you want all
 925        output not intended for machine consumption to use color, to
 926        `true` or `auto` (this is the default since Git 1.8.4) if you
 927        want such output to use color when written to the terminal.
 928
 929column.ui::
 930        Specify whether supported commands should output in columns.
 931        This variable consists of a list of tokens separated by spaces
 932        or commas:
 933+
 934--
 935`always`;;
 936        always show in columns
 937`never`;;
 938        never show in columns
 939`auto`;;
 940        show in columns if the output is to the terminal
 941`column`;;
 942        fill columns before rows (default)
 943`row`;;
 944        fill rows before columns
 945`plain`;;
 946        show in one column
 947`dense`;;
 948        make unequal size columns to utilize more space
 949`nodense`;;
 950        make equal size columns
 951--
 952+
 953This option defaults to 'never'.
 954
 955column.branch::
 956        Specify whether to output branch listing in `git branch` in columns.
 957        See `column.ui` for details.
 958
 959column.status::
 960        Specify whether to output untracked files in `git status` in columns.
 961        See `column.ui` for details.
 962
 963column.tag::
 964        Specify whether to output tag listing in `git tag` in columns.
 965        See `column.ui` for details.
 966
 967commit.cleanup::
 968        This setting overrides the default of the `--cleanup` option in
 969        `git commit`. See linkgit:git-commit[1] for details. Changing the
 970        default can be useful when you always want to keep lines that begin
 971        with comment character `#` in your log message, in which case you
 972        would do `git config commit.cleanup whitespace` (note that you will
 973        have to remove the help lines that begin with `#` in the commit log
 974        template yourself, if you do this).
 975
 976commit.status::
 977        A boolean to enable/disable inclusion of status information in the
 978        commit message template when using an editor to prepare the commit
 979        message.  Defaults to true.
 980
 981commit.template::
 982        Specify a file to use as the template for new commit messages.
 983        "`~/`" is expanded to the value of `$HOME` and "`~user/`" to the
 984        specified user's home directory.
 985
 986credential.helper::
 987        Specify an external helper to be called when a username or
 988        password credential is needed; the helper may consult external
 989        storage to avoid prompting the user for the credentials. See
 990        linkgit:gitcredentials[7] for details.
 991
 992credential.useHttpPath::
 993        When acquiring credentials, consider the "path" component of an http
 994        or https URL to be important. Defaults to false. See
 995        linkgit:gitcredentials[7] for more information.
 996
 997credential.username::
 998        If no username is set for a network authentication, use this username
 999        by default. See credential.<context>.* below, and
1000        linkgit:gitcredentials[7].
1001
1002credential.<url>.*::
1003        Any of the credential.* options above can be applied selectively to
1004        some credentials. For example "credential.https://example.com.username"
1005        would set the default username only for https connections to
1006        example.com. See linkgit:gitcredentials[7] for details on how URLs are
1007        matched.
1008
1009include::diff-config.txt[]
1010
1011difftool.<tool>.path::
1012        Override the path for the given tool.  This is useful in case
1013        your tool is not in the PATH.
1014
1015difftool.<tool>.cmd::
1016        Specify the command to invoke the specified diff tool.
1017        The specified command is evaluated in shell with the following
1018        variables available:  'LOCAL' is set to the name of the temporary
1019        file containing the contents of the diff pre-image and 'REMOTE'
1020        is set to the name of the temporary file containing the contents
1021        of the diff post-image.
1022
1023difftool.prompt::
1024        Prompt before each invocation of the diff tool.
1025
1026fetch.recurseSubmodules::
1027        This option can be either set to a boolean value or to 'on-demand'.
1028        Setting it to a boolean changes the behavior of fetch and pull to
1029        unconditionally recurse into submodules when set to true or to not
1030        recurse at all when set to false. When set to 'on-demand' (the default
1031        value), fetch and pull will only recurse into a populated submodule
1032        when its superproject retrieves a commit that updates the submodule's
1033        reference.
1034
1035fetch.fsckObjects::
1036        If it is set to true, git-fetch-pack will check all fetched
1037        objects. It will abort in the case of a malformed object or a
1038        broken link. The result of an abort are only dangling objects.
1039        Defaults to false. If not set, the value of `transfer.fsckObjects`
1040        is used instead.
1041
1042fetch.unpackLimit::
1043        If the number of objects fetched over the Git native
1044        transfer is below this
1045        limit, then the objects will be unpacked into loose object
1046        files. However if the number of received objects equals or
1047        exceeds this limit then the received pack will be stored as
1048        a pack, after adding any missing delta bases.  Storing the
1049        pack from a push can make the push operation complete faster,
1050        especially on slow filesystems.  If not set, the value of
1051        `transfer.unpackLimit` is used instead.
1052
1053format.attach::
1054        Enable multipart/mixed attachments as the default for
1055        'format-patch'.  The value can also be a double quoted string
1056        which will enable attachments as the default and set the
1057        value as the boundary.  See the --attach option in
1058        linkgit:git-format-patch[1].
1059
1060format.numbered::
1061        A boolean which can enable or disable sequence numbers in patch
1062        subjects.  It defaults to "auto" which enables it only if there
1063        is more than one patch.  It can be enabled or disabled for all
1064        messages by setting it to "true" or "false".  See --numbered
1065        option in linkgit:git-format-patch[1].
1066
1067format.headers::
1068        Additional email headers to include in a patch to be submitted
1069        by mail.  See linkgit:git-format-patch[1].
1070
1071format.to::
1072format.cc::
1073        Additional recipients to include in a patch to be submitted
1074        by mail.  See the --to and --cc options in
1075        linkgit:git-format-patch[1].
1076
1077format.subjectprefix::
1078        The default for format-patch is to output files with the '[PATCH]'
1079        subject prefix. Use this variable to change that prefix.
1080
1081format.signature::
1082        The default for format-patch is to output a signature containing
1083        the Git version number. Use this variable to change that default.
1084        Set this variable to the empty string ("") to suppress
1085        signature generation.
1086
1087format.suffix::
1088        The default for format-patch is to output files with the suffix
1089        `.patch`. Use this variable to change that suffix (make sure to
1090        include the dot if you want it).
1091
1092format.pretty::
1093        The default pretty format for log/show/whatchanged command,
1094        See linkgit:git-log[1], linkgit:git-show[1],
1095        linkgit:git-whatchanged[1].
1096
1097format.thread::
1098        The default threading style for 'git format-patch'.  Can be
1099        a boolean value, or `shallow` or `deep`.  `shallow` threading
1100        makes every mail a reply to the head of the series,
1101        where the head is chosen from the cover letter, the
1102        `--in-reply-to`, and the first patch mail, in this order.
1103        `deep` threading makes every mail a reply to the previous one.
1104        A true boolean value is the same as `shallow`, and a false
1105        value disables threading.
1106
1107format.signoff::
1108        A boolean value which lets you enable the `-s/--signoff` option of
1109        format-patch by default. *Note:* Adding the Signed-off-by: line to a
1110        patch should be a conscious act and means that you certify you have
1111        the rights to submit this work under the same open source license.
1112        Please see the 'SubmittingPatches' document for further discussion.
1113
1114format.coverLetter::
1115        A boolean that controls whether to generate a cover-letter when
1116        format-patch is invoked, but in addition can be set to "auto", to
1117        generate a cover-letter only when there's more than one patch.
1118
1119filter.<driver>.clean::
1120        The command which is used to convert the content of a worktree
1121        file to a blob upon checkin.  See linkgit:gitattributes[5] for
1122        details.
1123
1124filter.<driver>.smudge::
1125        The command which is used to convert the content of a blob
1126        object to a worktree file upon checkout.  See
1127        linkgit:gitattributes[5] for details.
1128
1129gc.aggressiveWindow::
1130        The window size parameter used in the delta compression
1131        algorithm used by 'git gc --aggressive'.  This defaults
1132        to 250.
1133
1134gc.auto::
1135        When there are approximately more than this many loose
1136        objects in the repository, `git gc --auto` will pack them.
1137        Some Porcelain commands use this command to perform a
1138        light-weight garbage collection from time to time.  The
1139        default value is 6700.  Setting this to 0 disables it.
1140
1141gc.autopacklimit::
1142        When there are more than this many packs that are not
1143        marked with `*.keep` file in the repository, `git gc
1144        --auto` consolidates them into one larger pack.  The
1145        default value is 50.  Setting this to 0 disables it.
1146
1147gc.packrefs::
1148        Running `git pack-refs` in a repository renders it
1149        unclonable by Git versions prior to 1.5.1.2 over dumb
1150        transports such as HTTP.  This variable determines whether
1151        'git gc' runs `git pack-refs`. This can be set to `notbare`
1152        to enable it within all non-bare repos or it can be set to a
1153        boolean value.  The default is `true`.
1154
1155gc.pruneexpire::
1156        When 'git gc' is run, it will call 'prune --expire 2.weeks.ago'.
1157        Override the grace period with this config variable.  The value
1158        "now" may be used to disable this  grace period and always prune
1159        unreachable objects immediately.
1160
1161gc.reflogexpire::
1162gc.<pattern>.reflogexpire::
1163        'git reflog expire' removes reflog entries older than
1164        this time; defaults to 90 days.  With "<pattern>" (e.g.
1165        "refs/stash") in the middle the setting applies only to
1166        the refs that match the <pattern>.
1167
1168gc.reflogexpireunreachable::
1169gc.<ref>.reflogexpireunreachable::
1170        'git reflog expire' removes reflog entries older than
1171        this time and are not reachable from the current tip;
1172        defaults to 30 days.  With "<pattern>" (e.g. "refs/stash")
1173        in the middle, the setting applies only to the refs that
1174        match the <pattern>.
1175
1176gc.rerereresolved::
1177        Records of conflicted merge you resolved earlier are
1178        kept for this many days when 'git rerere gc' is run.
1179        The default is 60 days.  See linkgit:git-rerere[1].
1180
1181gc.rerereunresolved::
1182        Records of conflicted merge you have not resolved are
1183        kept for this many days when 'git rerere gc' is run.
1184        The default is 15 days.  See linkgit:git-rerere[1].
1185
1186gitcvs.commitmsgannotation::
1187        Append this string to each commit message. Set to empty string
1188        to disable this feature. Defaults to "via git-CVS emulator".
1189
1190gitcvs.enabled::
1191        Whether the CVS server interface is enabled for this repository.
1192        See linkgit:git-cvsserver[1].
1193
1194gitcvs.logfile::
1195        Path to a log file where the CVS server interface well... logs
1196        various stuff. See linkgit:git-cvsserver[1].
1197
1198gitcvs.usecrlfattr::
1199        If true, the server will look up the end-of-line conversion
1200        attributes for files to determine the '-k' modes to use. If
1201        the attributes force Git to treat a file as text,
1202        the '-k' mode will be left blank so CVS clients will
1203        treat it as text. If they suppress text conversion, the file
1204        will be set with '-kb' mode, which suppresses any newline munging
1205        the client might otherwise do. If the attributes do not allow
1206        the file type to be determined, then 'gitcvs.allbinary' is
1207        used. See linkgit:gitattributes[5].
1208
1209gitcvs.allbinary::
1210        This is used if 'gitcvs.usecrlfattr' does not resolve
1211        the correct '-kb' mode to use. If true, all
1212        unresolved files are sent to the client in
1213        mode '-kb'. This causes the client to treat them
1214        as binary files, which suppresses any newline munging it
1215        otherwise might do. Alternatively, if it is set to "guess",
1216        then the contents of the file are examined to decide if
1217        it is binary, similar to 'core.autocrlf'.
1218
1219gitcvs.dbname::
1220        Database used by git-cvsserver to cache revision information
1221        derived from the Git repository. The exact meaning depends on the
1222        used database driver, for SQLite (which is the default driver) this
1223        is a filename. Supports variable substitution (see
1224        linkgit:git-cvsserver[1] for details). May not contain semicolons (`;`).
1225        Default: '%Ggitcvs.%m.sqlite'
1226
1227gitcvs.dbdriver::
1228        Used Perl DBI driver. You can specify any available driver
1229        for this here, but it might not work. git-cvsserver is tested
1230        with 'DBD::SQLite', reported to work with 'DBD::Pg', and
1231        reported *not* to work with 'DBD::mysql'. Experimental feature.
1232        May not contain double colons (`:`). Default: 'SQLite'.
1233        See linkgit:git-cvsserver[1].
1234
1235gitcvs.dbuser, gitcvs.dbpass::
1236        Database user and password. Only useful if setting 'gitcvs.dbdriver',
1237        since SQLite has no concept of database users and/or passwords.
1238        'gitcvs.dbuser' supports variable substitution (see
1239        linkgit:git-cvsserver[1] for details).
1240
1241gitcvs.dbTableNamePrefix::
1242        Database table name prefix.  Prepended to the names of any
1243        database tables used, allowing a single database to be used
1244        for several repositories.  Supports variable substitution (see
1245        linkgit:git-cvsserver[1] for details).  Any non-alphabetic
1246        characters will be replaced with underscores.
1247
1248All gitcvs variables except for 'gitcvs.usecrlfattr' and
1249'gitcvs.allbinary' can also be specified as
1250'gitcvs.<access_method>.<varname>' (where 'access_method'
1251is one of "ext" and "pserver") to make them apply only for the given
1252access method.

1270
1271grep.lineNumber::
1272        If set to true, enable '-n' option by default.
1273
1274grep.patternType::
1275        Set the default matching behavior. Using a value of 'basic', 'extended',
1276        'fixed', or 'perl' will enable the '--basic-regexp', '--extended-regexp',
1277        '--fixed-strings', or '--perl-regexp' option accordingly, while the
1278        value 'default' will return to the default matching behavior.
1279
1280grep.extendedRegexp::
1281        If set to true, enable '--extended-regexp' option by default. This
1282        option is ignored when the 'grep.patternType' option is set to a value
1283        other than 'default'.
1284
1285gpg.program::
1286        Use this custom program instead of "gpg" found on $PATH when
1287        making or verifying a PGP signature. The program must support the
1288        same command line interface as GPG, namely, to verify a detached
1289        signature, "gpg --verify $file - <$signature" is run, and the
1290        program is expected to signal a good signature by exiting with
1291        code 0, and to generate an ascii-armored detached signature, the
1292        standard input of "gpg -bsau $key" is fed with the contents to be
1293        signed, and the program is expected to send the result to its
1294        standard output.
1295
1296gui.commitmsgwidth::
1297        Defines how wide the commit message window is in the
1298        linkgit:git-gui[1]. "75" is the default.
1299
1300gui.diffcontext::
1301        Specifies how many context lines should be used in calls to diff
1302        made by the linkgit:git-gui[1]. The default is "5".
1303
1304gui.encoding::
1305        Specifies the default encoding to use for displaying of
1306        file contents in linkgit:git-gui[1] and linkgit:gitk[1].
1307        It can be overridden by setting the 'encoding' attribute
1308        for relevant files (see linkgit:gitattributes[5]).
1309        If this option is not set, the tools default to the
1310        locale encoding.
1311
1312gui.matchtrackingbranch::
1313        Determines if new branches created with linkgit:git-gui[1] should
1314        default to tracking remote branches with matching names or
1315        not. Default: "false".
1316
1317gui.newbranchtemplate::
1318        Is used as suggested name when creating new branches using the
1319        linkgit:git-gui[1].
1320
1321gui.pruneduringfetch::
1322        "true" if linkgit:git-gui[1] should prune remote-tracking branches when
1323        performing a fetch. The default value is "false".
1324
1325gui.trustmtime::
1326        Determines if linkgit:git-gui[1] should trust the file modification
1327        timestamp or not. By default the timestamps are not trusted.
1328
1329gui.spellingdictionary::
1330        Specifies the dictionary used for spell checking commit messages in
1331        the linkgit:git-gui[1]. When set to "none" spell checking is turned
1332        off.
1333
1334gui.fastcopyblame::
1335        If true, 'git gui blame' uses `-C` instead of `-C -C` for original
1336        location detection. It makes blame significantly faster on huge
1337        repositories at the expense of less thorough copy detection.
1338
1339gui.copyblamethreshold::
1340        Specifies the threshold to use in 'git gui blame' original location
1341        detection, measured in alphanumeric characters. See the
1342        linkgit:git-blame[1] manual for more information on copy detection.
1343
1344gui.blamehistoryctx::
1345        Specifies the radius of history context in days to show in
1346        linkgit:gitk[1] for the selected commit, when the `Show History
1347        Context` menu item is invoked from 'git gui blame'. If this
1348        variable is set to zero, the whole history is shown.
1349
1350guitool.<name>.cmd::
1351        Specifies the shell command line to execute when the corresponding item
1352        of the linkgit:git-gui[1] `Tools` menu is invoked. This option is
1353        mandatory for every tool. The command is executed from the root of
1354        the working directory, and in the environment it receives the name of
1355        the tool as 'GIT_GUITOOL', the name of the currently selected file as
1356        'FILENAME', and the name of the current branch as 'CUR_BRANCH' (if
1357        the head is detached, 'CUR_BRANCH' is empty).
1358
1359guitool.<name>.needsfile::
1360        Run the tool only if a diff is selected in the GUI. It guarantees
1361        that 'FILENAME' is not empty.
1362
1363guitool.<name>.noconsole::
1364        Run the command silently, without creating a window to display its
1365        output.
1366
1367guitool.<name>.norescan::
1368        Don't rescan the working directory for changes after the tool
1369        finishes execution.
1370
1371guitool.<name>.confirm::
1372        Show a confirmation dialog before actually running the tool.
1373
1374guitool.<name>.argprompt::
1375        Request a string argument from the user, and pass it to the tool
1376        through the 'ARGS' environment variable. Since requesting an
1377        argument implies confirmation, the 'confirm' option has no effect
1378        if this is enabled. If the option is set to 'true', 'yes', or '1',
1379        the dialog uses a built-in generic prompt; otherwise the exact
1380        value of the variable is used.
1381
1382guitool.<name>.revprompt::
1383        Request a single valid revision from the user, and set the
1384        'REVISION' environment variable. In other aspects this option
1385        is similar to 'argprompt', and can be used together with it.
1386
1387guitool.<name>.revunmerged::
1388        Show only unmerged branches in the 'revprompt' subdialog.
1389        This is useful for tools similar to merge or rebase, but not
1390        for things like checkout or reset.
1391
1392guitool.<name>.title::
1393        Specifies the title to use for the prompt dialog. The default
1394        is the tool name.
1395
1396guitool.<name>.prompt::
1397        Specifies the general prompt string to display at the top of
1398        the dialog, before subsections for 'argprompt' and 'revprompt'.
1399        The default value includes the actual command.
1400
1401help.browser::
1402        Specify the browser that will be used to display help in the
1403        'web' format. See linkgit:git-help[1].
1404
1405help.format::
1406        Override the default help format used by linkgit:git-help[1].
1407        Values 'man', 'info', 'web' and 'html' are supported. 'man' is
1408        the default. 'web' and 'html' are the same.
1409
1410help.autocorrect::
1411        Automatically correct and execute mistyped commands after
1412        waiting for the given number of deciseconds (0.1 sec). If more
1413        than one command can be deduced from the entered text, nothing
1414        will be executed.  If the value of this option is negative,
1415        the corrected command will be executed immediately. If the
1416        value is 0 - the command will be just shown but not executed.
1417        This is the default.
1418
1419help.htmlpath::
1420        Specify the path where the HTML documentation resides. File system paths
1421        and URLs are supported. HTML pages will be prefixed with this path when
1422        help is displayed in the 'web' format. This defaults to the documentation
1423        path of your Git installation.
1424
1425http.proxy::
1426        Override the HTTP proxy, normally configured using the 'http_proxy',
1427        'https_proxy', and 'all_proxy' environment variables (see
1428        `curl(1)`).  This can be overridden on a per-remote basis; see
1429        remote.<name>.proxy
1430
1431http.cookiefile::
1432        File containing previously stored cookie lines which should be used
1433        in the Git http session, if they match the server. The file format
1434        of the file to read cookies from should be plain HTTP headers or
1435        the Netscape/Mozilla cookie file format (see linkgit:curl[1]).
1436        NOTE that the file specified with http.cookiefile is only used as
1437        input. No cookies will be stored in the file.
1438
1439http.sslVerify::
1440        Whether to verify the SSL certificate when fetching or pushing
1441        over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
1442        variable.
1443
1444http.sslCert::
1445        File containing the SSL certificate when fetching or pushing
1446        over HTTPS. Can be overridden by the 'GIT_SSL_CERT' environment
1447        variable.
1448
1449http.sslKey::
1450        File containing the SSL private key when fetching or pushing
1451        over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment
1452        variable.
1453
1454http.sslCertPasswordProtected::
1455        Enable Git's password prompt for the SSL certificate.  Otherwise
1456        OpenSSL will prompt the user, possibly many times, if the
1457        certificate or private key is encrypted.  Can be overridden by the
1458        'GIT_SSL_CERT_PASSWORD_PROTECTED' environment variable.
1459
1460http.sslCAInfo::
1461        File containing the certificates to verify the peer with when
1462        fetching or pushing over HTTPS. Can be overridden by the
1463        'GIT_SSL_CAINFO' environment variable.
1464
1465http.sslCAPath::
1466        Path containing files with the CA certificates to verify the peer
1467        with when fetching or pushing over HTTPS. Can be overridden
1468        by the 'GIT_SSL_CAPATH' environment variable.
1469
1470http.sslTry::
1471        Attempt to use AUTH SSL/TLS and encrypted data transfers
1472        when connecting via regular FTP protocol. This might be needed
1473        if the FTP server requires it for security reasons or you wish
1474        to connect securely whenever remote FTP server supports it.
1475        Default is false since it might trigger certificate verification
1476        errors on misconfigured servers.
1477
1478http.maxRequests::
1479        How many HTTP requests to launch in parallel. Can be overridden
1480        by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5.
1481
1482http.minSessions::
1483        The number of curl sessions (counted across slots) to be kept across
1484        requests. They will not be ended with curl_easy_cleanup() until
1485        http_cleanup() is invoked. If USE_CURL_MULTI is not defined, this
1486        value will be capped at 1. Defaults to 1.
1487
1488http.postBuffer::
1489        Maximum size in bytes of the buffer used by smart HTTP
1490        transports when POSTing data to the remote system.
1491        For requests larger than this buffer size, HTTP/1.1 and
1492        Transfer-Encoding: chunked is used to avoid creating a
1493        massive pack file locally.  Default is 1 MiB, which is
1494        sufficient for most requests.
1495
1496http.lowSpeedLimit, http.lowSpeedTime::
1497        If the HTTP transfer speed is less than 'http.lowSpeedLimit'
1498        for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
1499        Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and
1500        'GIT_HTTP_LOW_SPEED_TIME' environment variables.
1501
1502http.noEPSV::
1503        A boolean which disables using of EPSV ftp command by curl.
1504        This can helpful with some "poor" ftp servers which don't
1505        support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
1506        environment variable. Default is false (curl will use EPSV).
1507
1508http.useragent::
1509        The HTTP USER_AGENT string presented to an HTTP server.  The default
1510        value represents the version of the client Git such as git/1.7.1.
1511        This option allows you to override this value to a more common value
1512        such as Mozilla/4.0.  This may be necessary, for instance, if
1513        connecting through a firewall that restricts HTTP connections to a set
1514        of common USER_AGENT strings (but not including those like git/1.7.1).
1515        Can be overridden by the 'GIT_HTTP_USER_AGENT' environment variable.
1516
1517i18n.commitEncoding::
1518        Character encoding the commit messages are stored in; Git itself
1519        does not care per se, but this information is necessary e.g. when
1520        importing commits from emails or in the gitk graphical history
1521        browser (and possibly at other places in the future or in other
1522        porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.
1523
1524i18n.logOutputEncoding::
1525        Character encoding the commit messages are converted to when
1526        running 'git log' and friends.
1527
1528imap::
1529        The configuration variables in the 'imap' section are described
1530        in linkgit:git-imap-send[1].
1531
1532init.templatedir::
1533        Specify the directory from which templates will be copied.
1534        (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].)
1535
1536instaweb.browser::
1537        Specify the program that will be used to browse your working
1538        repository in gitweb. See linkgit:git-instaweb[1].
1539
1540instaweb.httpd::
1541        The HTTP daemon command-line to start gitweb on your working
1542        repository. See linkgit:git-instaweb[1].
1543
1544instaweb.local::
1545        If true the web server started by linkgit:git-instaweb[1] will
1546        be bound to the local IP (127.0.0.1).
1547
1548instaweb.modulepath::
1549        The default module path for linkgit:git-instaweb[1] to use
1550        instead of /usr/lib/apache2/modules.  Only used if httpd
1551        is Apache.
1552
1553instaweb.port::
1554        The port number to bind the gitweb httpd to. See
1555        linkgit:git-instaweb[1].
1556
1557interactive.singlekey::
1558        In interactive commands, allow the user to provide one-letter
1559        input with a single key (i.e., without hitting enter).
1560        Currently this is used by the `--patch` mode of
1561        linkgit:git-add[1], linkgit:git-checkout[1], linkgit:git-commit[1],
1562        linkgit:git-reset[1], and linkgit:git-stash[1]. Note that this
1563        setting is silently ignored if portable keystroke input
1564        is not available.
1565
1566log.abbrevCommit::
1567        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
1568        linkgit:git-whatchanged[1] assume `--abbrev-commit`. You may
1569        override this option with `--no-abbrev-commit`.
1570
1571log.date::
1572        Set the default date-time mode for the 'log' command.
1573        Setting a value for log.date is similar to using 'git log''s
1574        `--date` option.  Possible values are `relative`, `local`,
1575        `default`, `iso`, `rfc`, and `short`; see linkgit:git-log[1]
1576        for details.
1577
1578log.decorate::
1579        Print out the ref names of any commits that are shown by the log
1580        command. If 'short' is specified, the ref name prefixes 'refs/heads/',
1581        'refs/tags/' and 'refs/remotes/' will not be printed. If 'full' is
1582        specified, the full ref name (including prefix) will be printed.
1583        This is the same as the log commands '--decorate' option.
1584
1585log.showroot::
1586        If true, the initial commit will be shown as a big creation event.
1587        This is equivalent to a diff against an empty tree.
1588        Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
1589        normally hide the root commit will now show it. True by default.
1590
1591log.mailmap::
1592        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
1593        linkgit:git-whatchanged[1] assume `--use-mailmap`.
1594
1595mailmap.file::
1596        The location of an augmenting mailmap file. The default
1597        mailmap, located in the root of the repository, is loaded
1598        first, then the mailmap file pointed to by this variable.
1599        The location of the mailmap file may be in a repository
1600        subdirectory, or somewhere outside of the repository itself.
1601        See linkgit:git-shortlog[1] and linkgit:git-blame[1].
1602
1603mailmap.blob::
1604        Like `mailmap.file`, but consider the value as a reference to a
1605        blob in the repository. If both `mailmap.file` and
1606        `mailmap.blob` are given, both are parsed, with entries from
1607        `mailmap.file` taking precedence. In a bare repository, this
1608        defaults to `HEAD:.mailmap`. In a non-bare repository, it
1609        defaults to empty.
1610
1611man.viewer::
1612        Specify the programs that may be used to display help in the
1613        'man' format. See linkgit:git-help[1].
1614
1615man.<tool>.cmd::
1616        Specify the command to invoke the specified man viewer. The
1617        specified command is evaluated in shell with the man page
1618        passed as argument. (See linkgit:git-help[1].)
1619
1620man.<tool>.path::
1621        Override the path for the given tool that may be used to
1622        display help in the 'man' format. See linkgit:git-help[1].
1623
1624include::merge-config.txt[]
1625
1626mergetool.<tool>.path::
1627        Override the path for the given tool.  This is useful in case
1628        your tool is not in the PATH.
1629
1630mergetool.<tool>.cmd::
1631        Specify the command to invoke the specified merge tool.  The
1632        specified command is evaluated in shell with the following
1633        variables available: 'BASE' is the name of a temporary file
1634        containing the common base of the files to be merged, if available;
1635        'LOCAL' is the name of a temporary file containing the contents of
1636        the file on the current branch; 'REMOTE' is the name of a temporary
1637        file containing the contents of the file from the branch being
1638        merged; 'MERGED' contains the name of the file to which the merge
1639        tool should write the results of a successful merge.
1640
1641mergetool.<tool>.trustExitCode::
1642        For a custom merge command, specify whether the exit code of
1643        the merge command can be used to determine whether the merge was
1644        successful.  If this is not set to true then the merge target file
1645        timestamp is checked and the merge assumed to have been successful
1646        if the file has been updated, otherwise the user is prompted to
1647        indicate the success of the merge.
1648
1649mergetool.keepBackup::
1650        After performing a merge, the original file with conflict markers
1651        can be saved as a file with a `.orig` extension.  If this variable
1652        is set to `false` then this file is not preserved.  Defaults to
1653        `true` (i.e. keep the backup files).
1654
1655mergetool.keepTemporaries::
1656        When invoking a custom merge tool, Git uses a set of temporary
1657        files to pass to the tool. If the tool returns an error and this
1658        variable is set to `true`, then these temporary files will be
1659        preserved, otherwise they will be removed after the tool has
1660        exited. Defaults to `false`.
1661
1662mergetool.prompt::
1663        Prompt before each invocation of the merge resolution program.
1664
1665notes.displayRef::
1666        The (fully qualified) refname from which to show notes when
1667        showing commit messages.  The value of this variable can be set
1668        to a glob, in which case notes from all matching refs will be
1669        shown.  You may also specify this configuration variable
1670        several times.  A warning will be issued for refs that do not
1671        exist, but a glob that does not match any refs is silently
1672        ignored.
1673+
1674This setting can be overridden with the `GIT_NOTES_DISPLAY_REF`
1675environment variable, which must be a colon separated list of refs or
1676globs.
1677+
1678The effective value of "core.notesRef" (possibly overridden by
1679GIT_NOTES_REF) is also implicitly added to the list of refs to be
1680displayed.
1681
1682notes.rewrite.<command>::
1683        When rewriting commits with <command> (currently `amend` or
1684        `rebase`) and this variable is set to `true`, Git
1685        automatically copies your notes from the original to the
1686        rewritten commit.  Defaults to `true`, but see
1687        "notes.rewriteRef" below.
1688
1689notes.rewriteMode::
1690        When copying notes during a rewrite (see the
1691        "notes.rewrite.<command>" option), determines what to do if
1692        the target commit already has a note.  Must be one of
1693        `overwrite`, `concatenate`, or `ignore`.  Defaults to
1694        `concatenate`.
1695+
1696This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
1697environment variable.
1698
1699notes.rewriteRef::
1700        When copying notes during a rewrite, specifies the (fully
1701        qualified) ref whose notes should be copied.  The ref may be a
1702        glob, in which case notes in all matching refs will be copied.
1703        You may also specify this configuration several times.
1704+
1705Does not have a default value; you must configure this variable to
1706enable note rewriting.  Set it to `refs/notes/commits` to enable
1707rewriting for the default commit notes.
1708+
1709This setting can be overridden with the `GIT_NOTES_REWRITE_REF`
1710environment variable, which must be a colon separated list of refs or
1711globs.
1712
1713pack.window::
1714        The size of the window used by linkgit:git-pack-objects[1] when no
1715        window size is given on the command line. Defaults to 10.
1716
1717pack.depth::
1718        The maximum delta depth used by linkgit:git-pack-objects[1] when no
1719        maximum depth is given on the command line. Defaults to 50.
1720
1721pack.windowMemory::
1722        The window memory size limit used by linkgit:git-pack-objects[1]
1723        when no limit is given on the command line.  The value can be
1724        suffixed with "k", "m", or "g".  Defaults to 0, meaning no
1725        limit.
1726
1727pack.compression::
1728        An integer -1..9, indicating the compression level for objects
1729        in a pack file. -1 is the zlib default. 0 means no
1730        compression, and 1..9 are various speed/size tradeoffs, 9 being
1731        slowest.  If not set,  defaults to core.compression.  If that is
1732        not set,  defaults to -1, the zlib default, which is "a default
1733        compromise between speed and compression (currently equivalent
1734        to level 6)."
1735+
1736Note that changing the compression level will not automatically recompress
1737all existing objects. You can force recompression by passing the -F option
1738to linkgit:git-repack[1].
1739
1740pack.deltaCacheSize::
1741        The maximum memory in bytes used for caching deltas in
1742        linkgit:git-pack-objects[1] before writing them out to a pack.
1743        This cache is used to speed up the writing object phase by not
1744        having to recompute the final delta result once the best match
1745        for all objects is found.  Repacking large repositories on machines
1746        which are tight with memory might be badly impacted by this though,
1747        especially if this cache pushes the system into swapping.
1748        A value of 0 means no limit. The smallest size of 1 byte may be
1749        used to virtually disable this cache. Defaults to 256 MiB.
1750
1751pack.deltaCacheLimit::
1752        The maximum size of a delta, that is cached in
1753        linkgit:git-pack-objects[1]. This cache is used to speed up the
1754        writing object phase by not having to recompute the final delta
1755        result once the best match for all objects is found. Defaults to 1000.
1756
1757pack.threads::
1758        Specifies the number of threads to spawn when searching for best
1759        delta matches.  This requires that linkgit:git-pack-objects[1]
1760        be compiled with pthreads otherwise this option is ignored with a
1761        warning. This is meant to reduce packing time on multiprocessor
1762        machines. The required amount of memory for the delta search window
1763        is however multiplied by the number of threads.
1764        Specifying 0 will cause Git to auto-detect the number of CPU's
1765        and set the number of threads accordingly.
1766
1767pack.indexVersion::
1768        Specify the default pack index version.  Valid values are 1 for
1769        legacy pack index used by Git versions prior to 1.5.2, and 2 for
1770        the new pack index with capabilities for packs larger than 4 GB
1771        as well as proper protection against the repacking of corrupted
1772        packs.  Version 2 is the default.  Note that version 2 is enforced
1773        and this config option ignored whenever the corresponding pack is
1774        larger than 2 GB.
1775+
1776If you have an old Git that does not understand the version 2 `*.idx` file,
1777cloning or fetching over a non native protocol (e.g. "http" and "rsync")
1778that will copy both `*.pack` file and corresponding `*.idx` file from the
1779other side may give you a repository that cannot be accessed with your
1780older version of Git. If the `*.pack` file is smaller than 2 GB, however,
1781you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
1782the `*.idx` file.
1783
1784pack.packSizeLimit::
1785        The maximum size of a pack.  This setting only affects
1786        packing to a file when repacking, i.e. the git:// protocol
1787        is unaffected.  It can be overridden by the `--max-pack-size`
1788        option of linkgit:git-repack[1]. The minimum size allowed is
1789        limited to 1 MiB. The default is unlimited.
1790        Common unit suffixes of 'k', 'm', or 'g' are
1791        supported.
1792
1793pager.<cmd>::
1794        If the value is boolean, turns on or off pagination of the
1795        output of a particular Git subcommand when writing to a tty.
1796        Otherwise, turns on pagination for the subcommand using the
1797        pager specified by the value of `pager.<cmd>`.  If `--paginate`
1798        or `--no-pager` is specified on the command line, it takes
1799        precedence over this option.  To disable pagination for all
1800        commands, set `core.pager` or `GIT_PAGER` to `cat`.
1801
1802pretty.<name>::
1803        Alias for a --pretty= format string, as specified in
1804        linkgit:git-log[1]. Any aliases defined here can be used just
1805        as the built-in pretty formats could. For example,
1806        running `git config pretty.changelog "format:* %H %s"`
1807        would cause the invocation `git log --pretty=changelog`
1808        to be equivalent to running `git log "--pretty=format:* %H %s"`.
1809        Note that an alias with the same name as a built-in format
1810        will be silently ignored.
1811
1812pull.rebase::
1813        When true, rebase branches on top of the fetched branch, instead
1814        of merging the default branch from the default remote when "git
1815        pull" is run. See "branch.<name>.rebase" for setting this on a
1816        per-branch basis.
1817+
1818*NOTE*: this is a possibly dangerous operation; do *not* use
1819it unless you understand the implications (see linkgit:git-rebase[1]
1820for details).
1821
1822pull.octopus::
1823        The default merge strategy to use when pulling multiple branches
1824        at once.
1825
1826pull.twohead::
1827        The default merge strategy to use when pulling a single branch.
1828
1829push.default::
1830        Defines the action `git push` should take if no refspec is given
1831        on the command line, no refspec is configured in the remote, and
1832        no refspec is implied by any of the options given on the command
1833        line. Possible values are:
1834+
1835--
1836* `nothing` - do not push anything.
1837* `matching` - push all branches having the same name in both ends.
1838  This is for those who prepare all the branches into a publishable
1839  shape and then push them out with a single command.  It is not
1840  appropriate for pushing into a repository shared by multiple users,
1841  since locally stalled branches will attempt a non-fast forward push
1842  if other users updated the branch.
1843  +
1844  This is currently the default, but Git 2.0 will change the default
1845  to `simple`.
1846* `upstream` - push the current branch to its upstream branch
1847  (`tracking` is a deprecated synonym for this).
1848  With this, `git push` will update the same remote ref as the one which
1849  is merged by `git pull`, making `push` and `pull` symmetrical.
1850  See "branch.<name>.merge" for how to configure the upstream branch.
1851* `simple` - like `upstream`, but refuses to push if the upstream
1852  branch's name is different from the local one. This is the safest
1853  option and is well-suited for beginners. It will become the default
1854  in Git 2.0.
1855* `current` - push the current branch to a branch of the same name.
1856--
1857+
1858The `simple`, `current` and `upstream` modes are for those who want to
1859push out a single branch after finishing work, even when the other
1860branches are not yet ready to be pushed out. If you are working with
1861other people to push into the same shared repository, you would want
1862to use one of these.
1863
1864rebase.stat::
1865        Whether to show a diffstat of what changed upstream since the last
1866        rebase. False by default.
1867
1868rebase.autosquash::
1869        If set to true enable '--autosquash' option by default.
1870
1871rebase.autostash::
1872        When set to true, automatically create a temporary stash
1873        before the operation begins, and apply it after the operation
1874        ends.  This means that you can run rebase on a dirty worktree.
1875        However, use with care: the final stash application after a
1876        successful rebase might result in non-trivial conflicts.
1877        Defaults to false.
1878
1879receive.autogc::
1880        By default, git-receive-pack will run "git-gc --auto" after
1881        receiving data from git-push and updating refs.  You can stop
1882        it by setting this variable to false.
1883
1884receive.fsckObjects::
1885        If it is set to true, git-receive-pack will check all received
1886        objects. It will abort in the case of a malformed object or a
1887        broken link. The result of an abort are only dangling objects.
1888        Defaults to false. If not set, the value of `transfer.fsckObjects`
1889        is used instead.
1890
1891receive.unpackLimit::
1892        If the number of objects received in a push is below this
1893        limit then the objects will be unpacked into loose object
1894        files. However if the number of received objects equals or
1895        exceeds this limit then the received pack will be stored as
1896        a pack, after adding any missing delta bases.  Storing the
1897        pack from a push can make the push operation complete faster,
1898        especially on slow filesystems.  If not set, the value of
1899        `transfer.unpackLimit` is used instead.
1900
1901receive.denyDeletes::
1902        If set to true, git-receive-pack will deny a ref update that deletes
1903        the ref. Use this to prevent such a ref deletion via a push.
1904
1905receive.denyDeleteCurrent::
1906        If set to true, git-receive-pack will deny a ref update that
1907        deletes the currently checked out branch of a non-bare repository.
1908
1909receive.denyCurrentBranch::
1910        If set to true or "refuse", git-receive-pack will deny a ref update
1911        to the currently checked out branch of a non-bare repository.
1912        Such a push is potentially dangerous because it brings the HEAD
1913        out of sync with the index and working tree. If set to "warn",
1914        print a warning of such a push to stderr, but allow the push to
1915        proceed. If set to false or "ignore", allow such pushes with no
1916        message. Defaults to "refuse".
1917
1918receive.denyNonFastForwards::
1919        If set to true, git-receive-pack will deny a ref update which is
1920        not a fast-forward. Use this to prevent such an update via a push,
1921        even if that push is forced. This configuration variable is
1922        set when initializing a shared repository.
1923
1924receive.hiderefs::
1925        String(s) `receive-pack` uses to decide which refs to omit
1926        from its initial advertisement.  Use more than one
1927        definitions to specify multiple prefix strings. A ref that
1928        are under the hierarchies listed on the value of this
1929        variable is excluded, and is hidden when responding to `git
1930        push`, and an attempt to update or delete a hidden ref by
1931        `git push` is rejected.
1932
1933receive.updateserverinfo::
1934        If set to true, git-receive-pack will run git-update-server-info
1935        after receiving data from git-push and updating refs.
1936
1937remote.pushdefault::
1938        The remote to push to by default.  Overrides
1939        `branch.<name>.remote` for all branches, and is overridden by
1940        `branch.<name>.pushremote` for specific branches.
1941
1942remote.<name>.url::
1943        The URL of a remote repository.  See linkgit:git-fetch[1] or
1944        linkgit:git-push[1].
1945
1946remote.<name>.pushurl::
1947        The push URL of a remote repository.  See linkgit:git-push[1].
1948
1949remote.<name>.proxy::
1950        For remotes that require curl (http, https and ftp), the URL to
1951        the proxy to use for that remote.  Set to the empty string to
1952        disable proxying for that remote.
1953
1954remote.<name>.fetch::
1955        The default set of "refspec" for linkgit:git-fetch[1]. See
1956        linkgit:git-fetch[1].
1957
1958remote.<name>.push::
1959        The default set of "refspec" for linkgit:git-push[1]. See
1960        linkgit:git-push[1].
1961
1962remote.<name>.mirror::
1963        If true, pushing to this remote will automatically behave
1964        as if the `--mirror` option was given on the command line.
1965
1966remote.<name>.skipDefaultUpdate::
1967        If true, this remote will be skipped by default when updating
1968        using linkgit:git-fetch[1] or the `update` subcommand of
1969        linkgit:git-remote[1].
1970
1971remote.<name>.skipFetchAll::
1972        If true, this remote will be skipped by default when updating
1973        using linkgit:git-fetch[1] or the `update` subcommand of
1974        linkgit:git-remote[1].
1975
1976remote.<name>.receivepack::
1977        The default program to execute on the remote side when pushing.  See
1978        option \--receive-pack of linkgit:git-push[1].
1979
1980remote.<name>.uploadpack::
1981        The default program to execute on the remote side when fetching.  See
1982        option \--upload-pack of linkgit:git-fetch-pack[1].
1983
1984remote.<name>.tagopt::
1985        Setting this value to \--no-tags disables automatic tag following when
1986        fetching from remote <name>. Setting it to \--tags will fetch every
1987        tag from remote <name>, even if they are not reachable from remote
1988        branch heads. Passing these flags directly to linkgit:git-fetch[1] can
1989        override this setting. See options \--tags and \--no-tags of
1990        linkgit:git-fetch[1].
1991
1992remote.<name>.vcs::
1993        Setting this to a value <vcs> will cause Git to interact with
1994        the remote with the git-remote-<vcs> helper.
1995
1996remotes.<group>::
1997        The list of remotes which are fetched by "git remote update
1998        <group>".  See linkgit:git-remote[1].
1999
2000repack.usedeltabaseoffset::
2001        By default, linkgit:git-repack[1] creates packs that use
2002        delta-base offset. If you need to share your repository with
2003        Git older than version 1.4.4, either directly or via a dumb
2004        protocol such as http, then you need to set this option to
2005        "false" and repack. Access from old Git versions over the
2006        native protocol are unaffected by this option.
2007
2008rerere.autoupdate::
2009        When set to true, `git-rerere` updates the index with the
2010        resulting contents after it cleanly resolves conflicts using
2011        previously recorded resolution.  Defaults to false.
2012
2013rerere.enabled::
2014        Activate recording of resolved conflicts, so that identical
2015        conflict hunks can be resolved automatically, should they be
2016        encountered again.  By default, linkgit:git-rerere[1] is
2017        enabled if there is an `rr-cache` directory under the
2018        `$GIT_DIR`, e.g. if "rerere" was previously used in the
2019        repository.
2020
2021sendemail.identity::
2022        A configuration identity. When given, causes values in the
2023        'sendemail.<identity>' subsection to take precedence over
2024        values in the 'sendemail' section. The default identity is
2025        the value of 'sendemail.identity'.
2026
2027sendemail.smtpencryption::
2028        See linkgit:git-send-email[1] for description.  Note that this
2029        setting is not subject to the 'identity' mechanism.
2030
2031sendemail.smtpssl::
2032        Deprecated alias for 'sendemail.smtpencryption = ssl'.
2033
2034sendemail.<identity>.*::
2035        Identity-specific versions of the 'sendemail.*' parameters
2036        found below, taking precedence over those when the this
2037        identity is selected, through command-line or
2038        'sendemail.identity'.
2039

2066        Deprecated alias for 'sendemail.signedoffbycc'.
2067
2068showbranch.default::
2069        The default set of branches for linkgit:git-show-branch[1].
2070        See linkgit:git-show-branch[1].
2071
2072status.relativePaths::
2073        By default, linkgit:git-status[1] shows paths relative to the
2074        current directory. Setting this variable to `false` shows paths
2075        relative to the repository root (this was the default for Git
2076        prior to v1.5.4).
2077
2078status.short::
2079        Set to true to enable --short by default in linkgit:git-status[1].
2080        The option --no-short takes precedence over this variable.
2081
2082status.branch::
2083        Set to true to enable --branch by default in linkgit:git-status[1].
2084        The option --no-branch takes precedence over this variable.
2085
2086status.showUntrackedFiles::
2087        By default, linkgit:git-status[1] and linkgit:git-commit[1] show
2088        files which are not currently tracked by Git. Directories which
2089        contain only untracked files, are shown with the directory name
2090        only. Showing untracked files means that Git needs to lstat() all
2091        all the files in the whole repository, which might be slow on some
2092        systems. So, this variable controls how the commands displays
2093        the untracked files. Possible values are:
2094+
2095--
2096* `no` - Show no untracked files.
2097* `normal` - Show untracked files and directories.
2098* `all` - Show also individual files in untracked directories.
2099--
2100+
2101If this variable is not specified, it defaults to 'normal'.
2102This variable can be overridden with the -u|--untracked-files option
2103of linkgit:git-status[1] and linkgit:git-commit[1].
2104
2105status.submodulesummary::
2106        Defaults to false.
2107        If this is set to a non zero number or true (identical to -1 or an
2108        unlimited number), the submodule summary will be enabled and a
2109        summary of commits for modified submodules will be shown (see
2110        --summary-limit option of linkgit:git-submodule[1]).
2111
2112submodule.<name>.path::
2113submodule.<name>.url::
2114submodule.<name>.update::
2115        The path within this project, URL, and the updating strategy
2116        for a submodule.  These variables are initially populated
2117        by 'git submodule init'; edit them to override the
2118        URL and other values found in the `.gitmodules` file.  See
2119        linkgit:git-submodule[1] and linkgit:gitmodules[5] for details.
2120
2121submodule.<name>.branch::
2122        The remote branch name for a submodule, used by `git submodule
2123        update --remote`.  Set this option to override the value found in
2124        the `.gitmodules` file.  See linkgit:git-submodule[1] and
2125        linkgit:gitmodules[5] for details.
2126
2127submodule.<name>.fetchRecurseSubmodules::
2128        This option can be used to control recursive fetching of this
2129        submodule. It can be overridden by using the --[no-]recurse-submodules
2130        command line option to "git fetch" and "git pull".
2131        This setting will override that from in the linkgit:gitmodules[5]
2132        file.
2133
2134submodule.<name>.ignore::
2135        Defines under what circumstances "git status" and the diff family show
2136        a submodule as modified. When set to "all", it will never be considered
2137        modified, "dirty" will ignore all changes to the submodules work tree and
2138        takes only differences between the HEAD of the submodule and the commit
2139        recorded in the superproject into account. "untracked" will additionally
2140        let submodules with modified tracked files in their work tree show up.
2141        Using "none" (the default when this option is not set) also shows
2142        submodules that have untracked files in their work tree as changed.
2143        This setting overrides any setting made in .gitmodules for this submodule,
2144        both settings can be overridden on the command line by using the
2145        "--ignore-submodules" option.
2146
2147tar.umask::
2148        This variable can be used to restrict the permission bits of
2149        tar archive entries.  The default is 0002, which turns off the
2150        world write bit.  The special value "user" indicates that the
2151        archiving user's umask will be used instead.  See umask(2) and
2152        linkgit:git-archive[1].
2153
2154transfer.fsckObjects::
2155        When `fetch.fsckObjects` or `receive.fsckObjects` are
2156        not set, the value of this variable is used instead.
2157        Defaults to false.
2158
2159transfer.hiderefs::
2160        This variable can be used to set both `receive.hiderefs`
2161        and `uploadpack.hiderefs` at the same time to the same
2162        values.  See entries for these other variables.
2163
2164transfer.unpackLimit::
2165        When `fetch.unpackLimit` or `receive.unpackLimit` are
2166        not set, the value of this variable is used instead.
2167        The default value is 100.
2168
2169uploadpack.hiderefs::
2170        String(s) `upload-pack` uses to decide which refs to omit
2171        from its initial advertisement.  Use more than one
2172        definitions to specify multiple prefix strings. A ref that
2173        are under the hierarchies listed on the value of this
2174        variable is excluded, and is hidden from `git ls-remote`,
2175        `git fetch`, etc.  An attempt to fetch a hidden ref by `git
2176        fetch` will fail.  See also `uploadpack.allowtipsha1inwant`.
2177
2178uploadpack.allowtipsha1inwant::
2179        When `uploadpack.hiderefs` is in effect, allow `upload-pack`
2180        to accept a fetch request that asks for an object at the tip
2181        of a hidden ref (by default, such a request is rejected).
2182        see also `uploadpack.hiderefs`.
2183
2184url.<base>.insteadOf::
2185        Any URL that starts with this value will be rewritten to
2186        start, instead, with <base>. In cases where some site serves a
2187        large number of repositories, and serves them with multiple
2188        access methods, and some users need to use different access
2189        methods, this feature allows people to specify any of the
2190        equivalent URLs and have Git automatically rewrite the URL to
2191        the best alternative for the particular user, even for a
2192        never-before-seen repository on the site.  When more than one
2193        insteadOf strings match a given URL, the longest match is used.
2194
2195url.<base>.pushInsteadOf::
2196        Any URL that starts with this value will not be pushed to;
2197        instead, it will be rewritten to start with <base>, and the
2198        resulting URL will be pushed to. In cases where some site serves
2199        a large number of repositories, and serves them with multiple
2200        access methods, some of which do not allow push, this feature
2201        allows people to specify a pull-only URL and have Git
2202        automatically use an appropriate URL to push, even for a
2203        never-before-seen repository on the site.  When more than one
2204        pushInsteadOf strings match a given URL, the longest match is
2205        used.  If a remote has an explicit pushurl, Git will ignore this
2206        setting for that remote.
2207
2208user.email::
2209        Your email address to be recorded in any newly created commits.
2210        Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and
2211        'EMAIL' environment variables.  See linkgit:git-commit-tree[1].
2212
2213user.name::
2214        Your full name to be recorded in any newly created commits.
2215        Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
2216        environment variables.  See linkgit:git-commit-tree[1].
2217
2218user.signingkey::
2219        If linkgit:git-tag[1] is not selecting the key you want it to
2220        automatically when creating a signed tag, you can override the
2221        default selection with this variable.  This option is passed
2222        unchanged to gpg's --local-user parameter, so you may specify a key
2223        using any method that gpg supports.
2224
2225web.browser::
2226        Specify a web browser that may be used by some commands.
2227        Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
2228        may use it.
