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

 206                path = foo.inc
 207
 208Values
 209~~~~~~
 210
 211Values of many variables are treated as a simple string, but there
 212are variables that take values of specific types and there are rules
 213as to how to spell them.
 214
 215boolean::
 216
 217       When a variable is said to take a boolean value, many
 218       synonyms are accepted for 'true' and 'false'; these are all
 219       case-insensitive.
 220
 221        true;; Boolean true literals are `yes`, `on`, `true`,
 222                and `1`.  Also, a variable defined without `= <value>`
 223                is taken as true.
 224
 225        false;; Boolean false literals are `no`, `off`, `false`,
 226                `0` and the empty string.
 227+
 228When converting a value to its canonical form using the `--type=bool` type
 229specifier, 'git config' will ensure that the output is "true" or
 230"false" (spelled in lowercase).
 231
 232integer::
 233       The value for many variables that specify various sizes can
 234       be suffixed with `k`, `M`,... to mean "scale the number by
 235       1024", "by 1024x1024", etc.
 236
 237color::
 238       The value for a variable that takes a color is a list of
 239       colors (at most two, one for foreground and one for background)
 240       and attributes (as many as you want), separated by spaces.
 241+
 242The basic colors accepted are `normal`, `black`, `red`, `green`, `yellow`,
 243`blue`, `magenta`, `cyan` and `white`.  The first color given is the
 244foreground; the second is the background.
 245+
 246Colors may also be given as numbers between 0 and 255; these use ANSI
 247256-color mode (but note that not all terminals may support this).  If
 248your terminal supports it, you may also specify 24-bit RGB values as
 249hex, like `#ff0ab3`.
 250+
 251The accepted attributes are `bold`, `dim`, `ul`, `blink`, `reverse`,
 252`italic`, and `strike` (for crossed-out or "strikethrough" letters).
 253The position of any attributes with respect to the colors
 254(before, after, or in between), doesn't matter. Specific attributes may
 255be turned off by prefixing them with `no` or `no-` (e.g., `noreverse`,
 256`no-ul`, etc).
 257+
 258An empty color string produces no color effect at all. This can be used
 259to avoid coloring specific elements without disabling color entirely.
 260+
 261For git's pre-defined color slots, the attributes are meant to be reset
 262at the beginning of each item in the colored output. So setting
 263`color.decorate.branch` to `black` will paint that branch name in a
 264plain `black`, even if the previous thing on the same output line (e.g.
 265opening parenthesis before the list of branch names in `log --decorate`
 266output) is set to be painted with `bold` or some other attribute.
 267However, custom log formats may do more complicated and layered
 268coloring, and the negated forms may be useful there.
 269
 270pathname::
 271        A variable that takes a pathname value can be given a
 272        string that begins with "`~/`" or "`~user/`", and the usual
 273        tilde expansion happens to such a string: `~/`
 274        is expanded to the value of `$HOME`, and `~user/` to the
 275        specified user's home directory.
 276
 277
 278Variables
 279~~~~~~~~~
 280
 281Note that this list is non-comprehensive and not necessarily complete.
 282For command-specific variables, you will find a more detailed description
 283in the appropriate manual page.
 284
 285Other git-related tools may and do use their own variables.  When
 286inventing new variables for use in your own tool, make sure their
 287names do not conflict with those that are used by Git itself and
 288other popular tools, and describe them in your documentation.

 372man.viewer::
 373        Specify the programs that may be used to display help in the
 374        'man' format. See linkgit:git-help[1].
 375
 376man.<tool>.cmd::
 377        Specify the command to invoke the specified man viewer. The
 378        specified command is evaluated in shell with the man page
 379        passed as argument. (See linkgit:git-help[1].)
 380
 381man.<tool>.path::
 382        Override the path for the given tool that may be used to
 383        display help in the 'man' format. See linkgit:git-help[1].
 384
 385include::merge-config.txt[]
 386
 387mergetool.<tool>.path::
 388        Override the path for the given tool.  This is useful in case
 389        your tool is not in the PATH.
 390
 391mergetool.<tool>.cmd::
 392        Specify the command to invoke the specified merge tool.  The
 393        specified command is evaluated in shell with the following
 394        variables available: 'BASE' is the name of a temporary file
 395        containing the common base of the files to be merged, if available;
 396        'LOCAL' is the name of a temporary file containing the contents of
 397        the file on the current branch; 'REMOTE' is the name of a temporary
 398        file containing the contents of the file from the branch being
 399        merged; 'MERGED' contains the name of the file to which the merge
 400        tool should write the results of a successful merge.
 401
 402mergetool.<tool>.trustExitCode::
 403        For a custom merge command, specify whether the exit code of
 404        the merge command can be used to determine whether the merge was
 405        successful.  If this is not set to true then the merge target file
 406        timestamp is checked and the merge assumed to have been successful
 407        if the file has been updated, otherwise the user is prompted to
 408        indicate the success of the merge.
 409
 410mergetool.meld.hasOutput::
 411        Older versions of `meld` do not support the `--output` option.
 412        Git will attempt to detect whether `meld` supports `--output`
 413        by inspecting the output of `meld --help`.  Configuring
 414        `mergetool.meld.hasOutput` will make Git skip these checks and
 415        use the configured value instead.  Setting `mergetool.meld.hasOutput`
 416        to `true` tells Git to unconditionally use the `--output` option,
 417        and `false` avoids using `--output`.
 418
 419mergetool.keepBackup::
 420        After performing a merge, the original file with conflict markers
 421        can be saved as a file with a `.orig` extension.  If this variable
 422        is set to `false` then this file is not preserved.  Defaults to
 423        `true` (i.e. keep the backup files).
 424
 425mergetool.keepTemporaries::
 426        When invoking a custom merge tool, Git uses a set of temporary
 427        files to pass to the tool. If the tool returns an error and this
 428        variable is set to `true`, then these temporary files will be
 429        preserved, otherwise they will be removed after the tool has
 430        exited. Defaults to `false`.
 431
 432mergetool.writeToTemp::
 433        Git writes temporary 'BASE', 'LOCAL', and 'REMOTE' versions of
 434        conflicting files in the worktree by default.  Git will attempt
 435        to use a temporary directory for these files when set `true`.
 436        Defaults to `false`.
 437
 438mergetool.prompt::
 439        Prompt before each invocation of the merge resolution program.
 440
 441notes.mergeStrategy::
 442        Which merge strategy to choose by default when resolving notes
 443        conflicts.  Must be one of `manual`, `ours`, `theirs`, `union`, or
 444        `cat_sort_uniq`.  Defaults to `manual`.  See "NOTES MERGE STRATEGIES"
 445        section of linkgit:git-notes[1] for more information on each strategy.
 446
 447notes.<name>.mergeStrategy::
 448        Which merge strategy to choose when doing a notes merge into
 449        refs/notes/<name>.  This overrides the more general
 450        "notes.mergeStrategy".  See the "NOTES MERGE STRATEGIES" section in
 451        linkgit:git-notes[1] for more information on the available strategies.
 452
 453notes.displayRef::
 454        The (fully qualified) refname from which to show notes when
 455        showing commit messages.  The value of this variable can be set
 456        to a glob, in which case notes from all matching refs will be
 457        shown.  You may also specify this configuration variable
 458        several times.  A warning will be issued for refs that do not
 459        exist, but a glob that does not match any refs is silently
 460        ignored.
 461+
 462This setting can be overridden with the `GIT_NOTES_DISPLAY_REF`
 463environment variable, which must be a colon separated list of refs or
 464globs.
 465+
 466The effective value of "core.notesRef" (possibly overridden by
 467GIT_NOTES_REF) is also implicitly added to the list of refs to be
 468displayed.
 469
 470notes.rewrite.<command>::
 471        When rewriting commits with <command> (currently `amend` or
 472        `rebase`) and this variable is set to `true`, Git
 473        automatically copies your notes from the original to the
 474        rewritten commit.  Defaults to `true`, but see
 475        "notes.rewriteRef" below.
 476
 477notes.rewriteMode::
 478        When copying notes during a rewrite (see the
 479        "notes.rewrite.<command>" option), determines what to do if
 480        the target commit already has a note.  Must be one of
 481        `overwrite`, `concatenate`, `cat_sort_uniq`, or `ignore`.
 482        Defaults to `concatenate`.
 483+
 484This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
 485environment variable.
 486
 487notes.rewriteRef::
 488        When copying notes during a rewrite, specifies the (fully
 489        qualified) ref whose notes should be copied.  The ref may be a
 490        glob, in which case notes in all matching refs will be copied.
 491        You may also specify this configuration several times.
 492+
 493Does not have a default value; you must configure this variable to
 494enable note rewriting.  Set it to `refs/notes/commits` to enable
 495rewriting for the default commit notes.
 496+
 497This setting can be overridden with the `GIT_NOTES_REWRITE_REF`
 498environment variable, which must be a colon separated list of refs or
 499globs.
 500
 501pack.window::
 502        The size of the window used by linkgit:git-pack-objects[1] when no
 503        window size is given on the command line. Defaults to 10.
 504
 505pack.depth::
 506        The maximum delta depth used by linkgit:git-pack-objects[1] when no
 507        maximum depth is given on the command line. Defaults to 50.
 508        Maximum value is 4095.
 509
 510pack.windowMemory::
 511        The maximum size of memory that is consumed by each thread
 512        in linkgit:git-pack-objects[1] for pack window memory when
 513        no limit is given on the command line.  The value can be
 514        suffixed with "k", "m", or "g".  When left unconfigured (or
 515        set explicitly to 0), there will be no limit.
 516
 517pack.compression::
 518        An integer -1..9, indicating the compression level for objects
 519        in a pack file. -1 is the zlib default. 0 means no
 520        compression, and 1..9 are various speed/size tradeoffs, 9 being
 521        slowest.  If not set,  defaults to core.compression.  If that is
 522        not set,  defaults to -1, the zlib default, which is "a default
 523        compromise between speed and compression (currently equivalent
 524        to level 6)."
 525+
 526Note that changing the compression level will not automatically recompress
 527all existing objects. You can force recompression by passing the -F option
 528to linkgit:git-repack[1].
 529
 530pack.island::
 531        An extended regular expression configuring a set of delta
 532        islands. See "DELTA ISLANDS" in linkgit:git-pack-objects[1]
 533        for details.
 534
 535pack.islandCore::
 536        Specify an island name which gets to have its objects be
 537        packed first. This creates a kind of pseudo-pack at the front
 538        of one pack, so that the objects from the specified island are
 539        hopefully faster to copy into any pack that should be served
 540        to a user requesting these objects. In practice this means
 541        that the island specified should likely correspond to what is
 542        the most commonly cloned in the repo. See also "DELTA ISLANDS"
 543        in linkgit:git-pack-objects[1].
 544
 545pack.deltaCacheSize::
 546        The maximum memory in bytes used for caching deltas in
 547        linkgit:git-pack-objects[1] before writing them out to a pack.
 548        This cache is used to speed up the writing object phase by not
 549        having to recompute the final delta result once the best match
 550        for all objects is found.  Repacking large repositories on machines
 551        which are tight with memory might be badly impacted by this though,
 552        especially if this cache pushes the system into swapping.
 553        A value of 0 means no limit. The smallest size of 1 byte may be
 554        used to virtually disable this cache. Defaults to 256 MiB.
 555
 556pack.deltaCacheLimit::
 557        The maximum size of a delta, that is cached in
 558        linkgit:git-pack-objects[1]. This cache is used to speed up the
 559        writing object phase by not having to recompute the final delta
 560        result once the best match for all objects is found.
 561        Defaults to 1000. Maximum value is 65535.
 562
 563pack.threads::
 564        Specifies the number of threads to spawn when searching for best
 565        delta matches.  This requires that linkgit:git-pack-objects[1]
 566        be compiled with pthreads otherwise this option is ignored with a
 567        warning. This is meant to reduce packing time on multiprocessor
 568        machines. The required amount of memory for the delta search window
 569        is however multiplied by the number of threads.
 570        Specifying 0 will cause Git to auto-detect the number of CPU's
 571        and set the number of threads accordingly.
 572
 573pack.indexVersion::
 574        Specify the default pack index version.  Valid values are 1 for
 575        legacy pack index used by Git versions prior to 1.5.2, and 2 for
 576        the new pack index with capabilities for packs larger than 4 GB
 577        as well as proper protection against the repacking of corrupted
 578        packs.  Version 2 is the default.  Note that version 2 is enforced
 579        and this config option ignored whenever the corresponding pack is
 580        larger than 2 GB.
 581+
 582If you have an old Git that does not understand the version 2 `*.idx` file,
 583cloning or fetching over a non native protocol (e.g. "http")
 584that will copy both `*.pack` file and corresponding `*.idx` file from the
 585other side may give you a repository that cannot be accessed with your
 586older version of Git. If the `*.pack` file is smaller than 2 GB, however,
 587you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
 588the `*.idx` file.
 589
 590pack.packSizeLimit::
 591        The maximum size of a pack.  This setting only affects
 592        packing to a file when repacking, i.e. the git:// protocol
 593        is unaffected.  It can be overridden by the `--max-pack-size`
 594        option of linkgit:git-repack[1].  Reaching this limit results
 595        in the creation of multiple packfiles; which in turn prevents
 596        bitmaps from being created.
 597        The minimum size allowed is limited to 1 MiB.
 598        The default is unlimited.
 599        Common unit suffixes of 'k', 'm', or 'g' are
 600        supported.
 601
 602pack.useBitmaps::
 603        When true, git will use pack bitmaps (if available) when packing
 604        to stdout (e.g., during the server side of a fetch). Defaults to
 605        true. You should not generally need to turn this off unless
 606        you are debugging pack bitmaps.
 607
 608pack.writeBitmaps (deprecated)::
 609        This is a deprecated synonym for `repack.writeBitmaps`.
 610
 611pack.writeBitmapHashCache::
 612        When true, git will include a "hash cache" section in the bitmap
 613        index (if one is written). This cache can be used to feed git's
 614        delta heuristics, potentially leading to better deltas between
 615        bitmapped and non-bitmapped objects (e.g., when serving a fetch
 616        between an older, bitmapped pack and objects that have been
 617        pushed since the last gc). The downside is that it consumes 4
 618        bytes per object of disk space, and that JGit's bitmap
 619        implementation does not understand it, causing it to complain if
 620        Git and JGit are used on the same repository. Defaults to false.
 621
 622pager.<cmd>::
 623        If the value is boolean, turns on or off pagination of the
 624        output of a particular Git subcommand when writing to a tty.
 625        Otherwise, turns on pagination for the subcommand using the
 626        pager specified by the value of `pager.<cmd>`.  If `--paginate`
 627        or `--no-pager` is specified on the command line, it takes
 628        precedence over this option.  To disable pagination for all
 629        commands, set `core.pager` or `GIT_PAGER` to `cat`.
 630
 631pretty.<name>::
 632        Alias for a --pretty= format string, as specified in
 633        linkgit:git-log[1]. Any aliases defined here can be used just
 634        as the built-in pretty formats could. For example,
 635        running `git config pretty.changelog "format:* %H %s"`
 636        would cause the invocation `git log --pretty=changelog`
 637        to be equivalent to running `git log "--pretty=format:* %H %s"`.
 638        Note that an alias with the same name as a built-in format
 639        will be silently ignored.
 640
 641protocol.allow::
 642        If set, provide a user defined default policy for all protocols which
 643        don't explicitly have a policy (`protocol.<name>.allow`).  By default,
 644        if unset, known-safe protocols (http, https, git, ssh, file) have a
 645        default policy of `always`, known-dangerous protocols (ext) have a
 646        default policy of `never`, and all other protocols have a default
 647        policy of `user`.  Supported policies:
 648+
 649--
 650
 651* `always` - protocol is always able to be used.
 652
 653* `never` - protocol is never able to be used.
 654
 655* `user` - protocol is only able to be used when `GIT_PROTOCOL_FROM_USER` is
 656  either unset or has a value of 1.  This policy should be used when you want a
 657  protocol to be directly usable by the user but don't want it used by commands which
 658  execute clone/fetch/push commands without user input, e.g. recursive
 659  submodule initialization.
 660
 661--
 662
 663protocol.<name>.allow::
 664        Set a policy to be used by protocol `<name>` with clone/fetch/push
 665        commands. See `protocol.allow` above for the available policies.
 666+
 667The protocol names currently used by git are:
 668+
 669--
 670  - `file`: any local file-based path (including `file://` URLs,
 671    or local paths)
 672
 673  - `git`: the anonymous git protocol over a direct TCP
 674    connection (or proxy, if configured)
 675
 676  - `ssh`: git over ssh (including `host:path` syntax,
 677    `ssh://`, etc).
 678
 679  - `http`: git over http, both "smart http" and "dumb http".
 680    Note that this does _not_ include `https`; if you want to configure
 681    both, you must do so individually.
 682
 683  - any external helpers are named by their protocol (e.g., use
 684    `hg` to allow the `git-remote-hg` helper)
 685--
 686
 687protocol.version::
 688        Experimental. If set, clients will attempt to communicate with a
 689        server using the specified protocol version.  If unset, no
 690        attempt will be made by the client to communicate using a
 691        particular protocol version, this results in protocol version 0
 692        being used.
 693        Supported versions:
 694+
 695--
 696
 697* `0` - the original wire protocol.
 698
 699* `1` - the original wire protocol with the addition of a version string
 700  in the initial response from the server.
 701
 702* `2` - link:technical/protocol-v2.html[wire protocol version 2].

 714remote.pushDefault::
 715        The remote to push to by default.  Overrides
 716        `branch.<name>.remote` for all branches, and is overridden by
 717        `branch.<name>.pushRemote` for specific branches.
 718
 719remote.<name>.url::
 720        The URL of a remote repository.  See linkgit:git-fetch[1] or
 721        linkgit:git-push[1].
 722
 723remote.<name>.pushurl::
 724        The push URL of a remote repository.  See linkgit:git-push[1].
 725
 726remote.<name>.proxy::
 727        For remotes that require curl (http, https and ftp), the URL to
 728        the proxy to use for that remote.  Set to the empty string to
 729        disable proxying for that remote.
 730
 731remote.<name>.proxyAuthMethod::
 732        For remotes that require curl (http, https and ftp), the method to use for
 733        authenticating against the proxy in use (probably set in
 734        `remote.<name>.proxy`). See `http.proxyAuthMethod`.
 735
 736remote.<name>.fetch::
 737        The default set of "refspec" for linkgit:git-fetch[1]. See
 738        linkgit:git-fetch[1].
 739
 740remote.<name>.push::
 741        The default set of "refspec" for linkgit:git-push[1]. See
 742        linkgit:git-push[1].
 743
 744remote.<name>.mirror::
 745        If true, pushing to this remote will automatically behave
 746        as if the `--mirror` option was given on the command line.
 747
 748remote.<name>.skipDefaultUpdate::
 749        If true, this remote will be skipped by default when updating
 750        using linkgit:git-fetch[1] or the `update` subcommand of
 751        linkgit:git-remote[1].
 752
 753remote.<name>.skipFetchAll::
 754        If true, this remote will be skipped by default when updating
 755        using linkgit:git-fetch[1] or the `update` subcommand of
 756        linkgit:git-remote[1].
 757
 758remote.<name>.receivepack::
 759        The default program to execute on the remote side when pushing.  See
 760        option --receive-pack of linkgit:git-push[1].
 761
 762remote.<name>.uploadpack::
 763        The default program to execute on the remote side when fetching.  See
 764        option --upload-pack of linkgit:git-fetch-pack[1].
 765
 766remote.<name>.tagOpt::
 767        Setting this value to --no-tags disables automatic tag following when
 768        fetching from remote <name>. Setting it to --tags will fetch every
 769        tag from remote <name>, even if they are not reachable from remote
 770        branch heads. Passing these flags directly to linkgit:git-fetch[1] can
 771        override this setting. See options --tags and --no-tags of
 772        linkgit:git-fetch[1].
 773
 774remote.<name>.vcs::
 775        Setting this to a value <vcs> will cause Git to interact with
 776        the remote with the git-remote-<vcs> helper.
 777
 778remote.<name>.prune::
 779        When set to true, fetching from this remote by default will also
 780        remove any remote-tracking references that no longer exist on the
 781        remote (as if the `--prune` option was given on the command line).
 782        Overrides `fetch.prune` settings, if any.
 783
 784remote.<name>.pruneTags::
 785        When set to true, fetching from this remote by default will also
 786        remove any local tags that no longer exist on the remote if pruning
 787        is activated in general via `remote.<name>.prune`, `fetch.prune` or
 788        `--prune`. Overrides `fetch.pruneTags` settings, if any.
 789+
 790See also `remote.<name>.prune` and the PRUNING section of
 791linkgit:git-fetch[1].
 792
 793remotes.<group>::
 794        The list of remotes which are fetched by "git remote update
 795        <group>".  See linkgit:git-remote[1].
 796
 797repack.useDeltaBaseOffset::
 798        By default, linkgit:git-repack[1] creates packs that use
 799        delta-base offset. If you need to share your repository with
 800        Git older than version 1.4.4, either directly or via a dumb
 801        protocol such as http, then you need to set this option to
 802        "false" and repack. Access from old Git versions over the
 803        native protocol are unaffected by this option.
 804
 805repack.packKeptObjects::
 806        If set to true, makes `git repack` act as if
 807        `--pack-kept-objects` was passed. See linkgit:git-repack[1] for
 808        details. Defaults to `false` normally, but `true` if a bitmap
 809        index is being written (either via `--write-bitmap-index` or
 810        `repack.writeBitmaps`).
 811
 812repack.useDeltaIslands::
 813        If set to true, makes `git repack` act as if `--delta-islands`
 814        was passed. Defaults to `false`.
 815
 816repack.writeBitmaps::
 817        When true, git will write a bitmap index when packing all
 818        objects to disk (e.g., when `git repack -a` is run).  This
 819        index can speed up the "counting objects" phase of subsequent
 820        packs created for clones and fetches, at the cost of some disk
 821        space and extra time spent on the initial repack.  This has
 822        no effect if multiple packfiles are created.
 823        Defaults to false.
 824
 825rerere.autoUpdate::
 826        When set to true, `git-rerere` updates the index with the
 827        resulting contents after it cleanly resolves conflicts using
 828        previously recorded resolution.  Defaults to false.
 829
 830rerere.enabled::
 831        Activate recording of resolved conflicts, so that identical
 832        conflict hunks can be resolved automatically, should they be
 833        encountered again.  By default, linkgit:git-rerere[1] is
 834        enabled if there is an `rr-cache` directory under the
 835        `$GIT_DIR`, e.g. if "rerere" was previously used in the
 836        repository.
 837
 838reset.quiet::
 839        When set to true, 'git reset' will default to the '--quiet' option.
 840
 841include::sendemail-config.txt[]
 842
 843sequence.editor::
 844        Text editor used by `git rebase -i` for editing the rebase instruction file.
 845        The value is meant to be interpreted by the shell when it is used.
 846        It can be overridden by the `GIT_SEQUENCE_EDITOR` environment variable.
 847        When not configured the default commit message editor is used instead.
 848
 849showBranch.default::
 850        The default set of branches for linkgit:git-show-branch[1].
 851        See linkgit:git-show-branch[1].
 852
 853splitIndex.maxPercentChange::
 854        When the split index feature is used, this specifies the
 855        percent of entries the split index can contain compared to the
 856        total number of entries in both the split index and the shared
 857        index before a new shared index is written.
 858        The value should be between 0 and 100. If the value is 0 then
 859        a new shared index is always written, if it is 100 a new
 860        shared index is never written.
 861        By default the value is 20, so a new shared index is written
 862        if the number of entries in the split index would be greater
 863        than 20 percent of the total number of entries.
 864        See linkgit:git-update-index[1].
 865
 866splitIndex.sharedIndexExpire::
 867        When the split index feature is used, shared index files that
 868        were not modified since the time this variable specifies will
 869        be removed when a new shared index file is created. The value
 870        "now" expires all entries immediately, and "never" suppresses
 871        expiration altogether.
 872        The default value is "2.weeks.ago".
 873        Note that a shared index file is considered modified (for the
 874        purpose of expiration) each time a new split-index file is
 875        either created based on it or read from it.
 876        See linkgit:git-update-index[1].
 877
 878include::config/ssh.txt[]
 879
 880status.relativePaths::
 881        By default, linkgit:git-status[1] shows paths relative to the
 882        current directory. Setting this variable to `false` shows paths
 883        relative to the repository root (this was the default for Git
 884        prior to v1.5.4).
 885
 886status.short::
 887        Set to true to enable --short by default in linkgit:git-status[1].
 888        The option --no-short takes precedence over this variable.
 889
 890status.branch::
 891        Set to true to enable --branch by default in linkgit:git-status[1].
 892        The option --no-branch takes precedence over this variable.
 893
 894status.displayCommentPrefix::
 895        If set to true, linkgit:git-status[1] will insert a comment
 896        prefix before each output line (starting with
 897        `core.commentChar`, i.e. `#` by default). This was the
 898        behavior of linkgit:git-status[1] in Git 1.8.4 and previous.
 899        Defaults to false.
 900
 901status.renameLimit::
 902        The number of files to consider when performing rename detection
 903        in linkgit:git-status[1] and linkgit:git-commit[1]. Defaults to
 904        the value of diff.renameLimit.
 905
 906status.renames::
 907        Whether and how Git detects renames in linkgit:git-status[1] and
 908        linkgit:git-commit[1] .  If set to "false", rename detection is
 909        disabled. If set to "true", basic rename detection is enabled.
 910        If set to "copies" or "copy", Git will detect copies, as well.
 911        Defaults to the value of diff.renames.
 912
 913status.showStash::
 914        If set to true, linkgit:git-status[1] will display the number of
 915        entries currently stashed away.
 916        Defaults to false.
 917
 918status.showUntrackedFiles::
 919        By default, linkgit:git-status[1] and linkgit:git-commit[1] show
 920        files which are not currently tracked by Git. Directories which
 921        contain only untracked files, are shown with the directory name
 922        only. Showing untracked files means that Git needs to lstat() all
 923        the files in the whole repository, which might be slow on some
 924        systems. So, this variable controls how the commands displays
 925        the untracked files. Possible values are:
 926+
 927--
 928* `no` - Show no untracked files.
 929* `normal` - Show untracked files and directories.
 930* `all` - Show also individual files in untracked directories.
 931--
 932+
 933If this variable is not specified, it defaults to 'normal'.
 934This variable can be overridden with the -u|--untracked-files option
 935of linkgit:git-status[1] and linkgit:git-commit[1].
 936
 937status.submoduleSummary::
 938        Defaults to false.
 939        If this is set to a non zero number or true (identical to -1 or an
 940        unlimited number), the submodule summary will be enabled and a
 941        summary of commits for modified submodules will be shown (see
 942        --summary-limit option of linkgit:git-submodule[1]). Please note
 943        that the summary output command will be suppressed for all
 944        submodules when `diff.ignoreSubmodules` is set to 'all' or only
 945        for those submodules where `submodule.<name>.ignore=all`. The only
 946        exception to that rule is that status and commit will show staged
 947        submodule changes. To
 948        also view the summary for ignored submodules you can either use
 949        the --ignore-submodules=dirty command-line option or the 'git
 950        submodule summary' command, which shows a similar output but does
 951        not honor these settings.
 952
 953stash.showPatch::
 954        If this is set to true, the `git stash show` command without an
 955        option will show the stash entry in patch form.  Defaults to false.
 956        See description of 'show' command in linkgit:git-stash[1].
 957
 958stash.showStat::
 959        If this is set to true, the `git stash show` command without an
 960        option will show diffstat of the stash entry.  Defaults to true.
 961        See description of 'show' command in linkgit:git-stash[1].
 962
 963include::submodule-config.txt[]
 964
 965tag.forceSignAnnotated::
 966        A boolean to specify whether annotated tags created should be GPG signed.
 967        If `--annotate` is specified on the command line, it takes
 968        precedence over this option.
 969
 970tag.sort::
 971        This variable controls the sort ordering of tags when displayed by
 972        linkgit:git-tag[1]. Without the "--sort=<value>" option provided, the
 973        value of this variable will be used as the default.
 974
 975tar.umask::
 976        This variable can be used to restrict the permission bits of
 977        tar archive entries.  The default is 0002, which turns off the
 978        world write bit.  The special value "user" indicates that the
 979        archiving user's umask will be used instead.  See umask(2) and
 980        linkgit:git-archive[1].
 981
 982transfer.fsckObjects::
 983        When `fetch.fsckObjects` or `receive.fsckObjects` are
 984        not set, the value of this variable is used instead.
 985        Defaults to false.
 986+
 987When set, the fetch or receive will abort in the case of a malformed
 988object or a link to a nonexistent object. In addition, various other
 989issues are checked for, including legacy issues (see `fsck.<msg-id>`),
 990and potential security issues like the existence of a `.GIT` directory
 991or a malicious `.gitmodules` file (see the release notes for v2.2.1
 992and v2.17.1 for details). Other sanity and security checks may be
 993added in future releases.
 994+
 995On the receiving side, failing fsckObjects will make those objects
 996unreachable, see "QUARANTINE ENVIRONMENT" in
 997linkgit:git-receive-pack[1]. On the fetch side, malformed objects will
 998instead be left unreferenced in the repository.
 999+
1000Due to the non-quarantine nature of the `fetch.fsckObjects`
1001implementation it can not be relied upon to leave the object store
1002clean like `receive.fsckObjects` can.
1003+
1004As objects are unpacked they're written to the object store, so there
1005can be cases where malicious objects get introduced even though the
1006"fetch" failed, only to have a subsequent "fetch" succeed because only
1007new incoming objects are checked, not those that have already been
1008written to the object store. That difference in behavior should not be
1009relied upon. In the future, such objects may be quarantined for
1010"fetch" as well.
1011+
1012For now, the paranoid need to find some way to emulate the quarantine
1013environment if they'd like the same protection as "push". E.g. in the
1014case of an internal mirror do the mirroring in two steps, one to fetch
1015the untrusted objects, and then do a second "push" (which will use the
1016quarantine) to another internal repo, and have internal clients
1017consume this pushed-to repository, or embargo internal fetches and
1018only allow them once a full "fsck" has run (and no new fetches have
1019happened in the meantime).
1020
1021transfer.hideRefs::
1022        String(s) `receive-pack` and `upload-pack` use to decide which
1023        refs to omit from their initial advertisements.  Use more than
1024        one definition to specify multiple prefix strings. A ref that is
1025        under the hierarchies listed in the value of this variable is
1026        excluded, and is hidden when responding to `git push` or `git
1027        fetch`.  See `receive.hideRefs` and `uploadpack.hideRefs` for
1028        program-specific versions of this config.
1029+
1030You may also include a `!` in front of the ref name to negate the entry,
1031explicitly exposing it, even if an earlier entry marked it as hidden.
1032If you have multiple hideRefs values, later entries override earlier ones
1033(and entries in more-specific config files override less-specific ones).
1034+
1035If a namespace is in use, the namespace prefix is stripped from each
1036reference before it is matched against `transfer.hiderefs` patterns.
1037For example, if `refs/heads/master` is specified in `transfer.hideRefs` and
1038the current namespace is `foo`, then `refs/namespaces/foo/refs/heads/master`
1039is omitted from the advertisements but `refs/heads/master` and
1040`refs/namespaces/bar/refs/heads/master` are still advertised as so-called
1041"have" lines. In order to match refs before stripping, add a `^` in front of
1042the ref name. If you combine `!` and `^`, `!` must be specified first.
1043+
1044Even if you hide refs, a client may still be able to steal the target
1045objects via the techniques described in the "SECURITY" section of the
1046linkgit:gitnamespaces[7] man page; it's best to keep private data in a
1047separate repository.
1048
1049transfer.unpackLimit::
1050        When `fetch.unpackLimit` or `receive.unpackLimit` are
1051        not set, the value of this variable is used instead.
1052        The default value is 100.
1053
1054uploadarchive.allowUnreachable::
1055        If true, allow clients to use `git archive --remote` to request
1056        any tree, whether reachable from the ref tips or not. See the
1057        discussion in the "SECURITY" section of
1058        linkgit:git-upload-archive[1] for more details. Defaults to
1059        `false`.
1060
1061uploadpack.hideRefs::
1062        This variable is the same as `transfer.hideRefs`, but applies
1063        only to `upload-pack` (and so affects only fetches, not pushes).
1064        An attempt to fetch a hidden ref by `git fetch` will fail.  See
1065        also `uploadpack.allowTipSHA1InWant`.
1066
1067uploadpack.allowTipSHA1InWant::
1068        When `uploadpack.hideRefs` is in effect, allow `upload-pack`
1069        to accept a fetch request that asks for an object at the tip
1070        of a hidden ref (by default, such a request is rejected).
1071        See also `uploadpack.hideRefs`.  Even if this is false, a client
1072        may be able to steal objects via the techniques described in the
1073        "SECURITY" section of the linkgit:gitnamespaces[7] man page; it's
1074        best to keep private data in a separate repository.
1075
1076uploadpack.allowReachableSHA1InWant::
1077        Allow `upload-pack` to accept a fetch request that asks for an
1078        object that is reachable from any ref tip. However, note that
1079        calculating object reachability is computationally expensive.
1080        Defaults to `false`.  Even if this is false, a client may be able
1081        to steal objects via the techniques described in the "SECURITY"
1082        section of the linkgit:gitnamespaces[7] man page; it's best to
1083        keep private data in a separate repository.
1084
1085uploadpack.allowAnySHA1InWant::
1086        Allow `upload-pack` to accept a fetch request that asks for any
1087        object at all.
1088        Defaults to `false`.
1089
1090uploadpack.keepAlive::
1091        When `upload-pack` has started `pack-objects`, there may be a
1092        quiet period while `pack-objects` prepares the pack. Normally
1093        it would output progress information, but if `--quiet` was used
1094        for the fetch, `pack-objects` will output nothing at all until
1095        the pack data begins. Some clients and networks may consider
1096        the server to be hung and give up. Setting this option instructs
1097        `upload-pack` to send an empty keepalive packet every
1098        `uploadpack.keepAlive` seconds. Setting this option to 0
1099        disables keepalive packets entirely. The default is 5 seconds.
1100
1101uploadpack.packObjectsHook::
1102        If this option is set, when `upload-pack` would run
1103        `git pack-objects` to create a packfile for a client, it will
1104        run this shell command instead.  The `pack-objects` command and
1105        arguments it _would_ have run (including the `git pack-objects`
1106        at the beginning) are appended to the shell command. The stdin
1107        and stdout of the hook are treated as if `pack-objects` itself
1108        was run. I.e., `upload-pack` will feed input intended for
1109        `pack-objects` to the hook, and expects a completed packfile on
1110        stdout.
1111+
1112Note that this configuration variable is ignored if it is seen in the
1113repository-level config (this is a safety measure against fetching from
1114untrusted repositories).
1115
1116uploadpack.allowFilter::
1117        If this option is set, `upload-pack` will support partial
1118        clone and partial fetch object filtering.
1119
1120uploadpack.allowRefInWant::
1121        If this option is set, `upload-pack` will support the `ref-in-want`
1122        feature of the protocol version 2 `fetch` command.  This feature
1123        is intended for the benefit of load-balanced servers which may
1124        not have the same view of what OIDs their refs point to due to
1125        replication delay.
1126
1127url.<base>.insteadOf::
1128        Any URL that starts with this value will be rewritten to
1129        start, instead, with <base>. In cases where some site serves a
1130        large number of repositories, and serves them with multiple
1131        access methods, and some users need to use different access
1132        methods, this feature allows people to specify any of the
1133        equivalent URLs and have Git automatically rewrite the URL to
1134        the best alternative for the particular user, even for a
1135        never-before-seen repository on the site.  When more than one
1136        insteadOf strings match a given URL, the longest match is used.
1137+
1138Note that any protocol restrictions will be applied to the rewritten
1139URL. If the rewrite changes the URL to use a custom protocol or remote
1140helper, you may need to adjust the `protocol.*.allow` config to permit
1141the request.  In particular, protocols you expect to use for submodules
1142must be set to `always` rather than the default of `user`. See the
1143description of `protocol.allow` above.
1144
1145url.<base>.pushInsteadOf::
1146        Any URL that starts with this value will not be pushed to;
1147        instead, it will be rewritten to start with <base>, and the
1148        resulting URL will be pushed to. In cases where some site serves
1149        a large number of repositories, and serves them with multiple
1150        access methods, some of which do not allow push, this feature
1151        allows people to specify a pull-only URL and have Git
1152        automatically use an appropriate URL to push, even for a
1153        never-before-seen repository on the site.  When more than one
1154        pushInsteadOf strings match a given URL, the longest match is
1155        used.  If a remote has an explicit pushurl, Git will ignore this
1156        setting for that remote.
1157
1158user.email::
1159        Your email address to be recorded in any newly created commits.
1160        Can be overridden by the `GIT_AUTHOR_EMAIL`, `GIT_COMMITTER_EMAIL`, and
1161        `EMAIL` environment variables.  See linkgit:git-commit-tree[1].
1162
1163user.name::
1164        Your full name to be recorded in any newly created commits.
1165        Can be overridden by the `GIT_AUTHOR_NAME` and `GIT_COMMITTER_NAME`
1166        environment variables.  See linkgit:git-commit-tree[1].
1167
1168user.useConfigOnly::
1169        Instruct Git to avoid trying to guess defaults for `user.email`
1170        and `user.name`, and instead retrieve the values only from the
1171        configuration. For example, if you have multiple email addresses
1172        and would like to use a different one for each repository, then
1173        with this configuration option set to `true` in the global config
1174        along with a name, Git will prompt you to set up an email before
1175        making new commits in a newly cloned repository.
1176        Defaults to `false`.
1177
1178user.signingKey::
1179        If linkgit:git-tag[1] or linkgit:git-commit[1] is not selecting the
1180        key you want it to automatically when creating a signed tag or
1181        commit, you can override the default selection with this variable.
1182        This option is passed unchanged to gpg's --local-user parameter,
1183        so you may specify a key using any method that gpg supports.
1184
1185versionsort.prereleaseSuffix (deprecated)::
1186        Deprecated alias for `versionsort.suffix`.  Ignored if
1187        `versionsort.suffix` is set.
1188
1189versionsort.suffix::
1190        Even when version sort is used in linkgit:git-tag[1], tagnames
1191        with the same base version but different suffixes are still sorted
1192        lexicographically, resulting e.g. in prerelease tags appearing
1193        after the main release (e.g. "1.0-rc1" after "1.0").  This
1194        variable can be specified to determine the sorting order of tags
1195        with different suffixes.
1196+
1197By specifying a single suffix in this variable, any tagname containing
1198that suffix will appear before the corresponding main release.  E.g. if
1199the variable is set to "-rc", then all "1.0-rcX" tags will appear before
1200"1.0".  If specified multiple times, once per suffix, then the order of
1201suffixes in the configuration will determine the sorting order of tagnames
1202with those suffixes.  E.g. if "-pre" appears before "-rc" in the
1203configuration, then all "1.0-preX" tags will be listed before any
1204"1.0-rcX" tags.  The placement of the main release tag relative to tags
1205with various suffixes can be determined by specifying the empty suffix
1206among those other suffixes.  E.g. if the suffixes "-rc", "", "-ck" and
1207"-bfs" appear in the configuration in this order, then all "v4.8-rcX" tags
1208are listed first, followed by "v4.8", then "v4.8-ckX" and finally
1209"v4.8-bfsX".
1210+
1211If more than one suffixes match the same tagname, then that tagname will
1212be sorted according to the suffix which starts at the earliest position in
1213the tagname.  If more than one different matching suffixes start at
1214that earliest position, then that tagname will be sorted according to the
1215longest of those suffixes.
1216The sorting order between different suffixes is undefined if they are
1217in multiple config files.
1218
1219web.browser::
1220        Specify a web browser that may be used by some commands.
1221        Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
1222        may use it.
1223
1224worktree.guessRemote::
1225        With `add`, if no branch argument, and neither of `-b` nor
1226        `-B` nor `--detach` are given, the command defaults to
1227        creating a new branch from HEAD.  If `worktree.guessRemote` is
1228        set to true, `worktree add` tries to find a remote-tracking
1229        branch whose name uniquely matches the new branch name.  If
1230        such a branch exists, it is checked out and set as "upstream"
1231        for the new branch.  If no such match can be found, it falls
1232        back to creating a new branch from the current HEAD.
