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

 207
 208Values
 209~~~~~~
 210
 211Values of many variables are treated as a simple string, but there
 212are variables that take values of specific types and there are rules
 213as to how to spell them.
 214
 215boolean::
 216
 217       When a variable is said to take a boolean value, many
 218       synonyms are accepted for 'true' and 'false'; these are all
 219       case-insensitive.
 220
 221        true;; Boolean true literals are `yes`, `on`, `true`,
 222                and `1`.  Also, a variable defined without `= <value>`
 223                is taken as true.
 224
 225        false;; Boolean false literals are `no`, `off`, `false`,
 226                `0` and the empty string.
 227+
 228When converting 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

 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.

 336gc.aggressiveDepth::
 337        The depth parameter used in the delta compression
 338        algorithm used by 'git gc --aggressive'.  This defaults
 339        to 50.
 340
 341gc.aggressiveWindow::
 342        The window size parameter used in the delta compression
 343        algorithm used by 'git gc --aggressive'.  This defaults
 344        to 250.
 345
 346gc.auto::
 347        When there are approximately more than this many loose
 348        objects in the repository, `git gc --auto` will pack them.
 349        Some Porcelain commands use this command to perform a
 350        light-weight garbage collection from time to time.  The
 351        default value is 6700.  Setting this to 0 disables it.
 352
 353gc.autoPackLimit::
 354        When there are more than this many packs that are not
 355        marked with `*.keep` file in the repository, `git gc
 356        --auto` consolidates them into one larger pack.  The
 357        default value is 50.  Setting this to 0 disables it.
 358
 359gc.autoDetach::
 360        Make `git gc --auto` return immediately and run in background
 361        if the system supports it. Default is true.
 362
 363gc.bigPackThreshold::
 364        If non-zero, all packs larger than this limit are kept when
 365        `git gc` is run. This is very similar to `--keep-base-pack`
 366        except that all packs that meet the threshold are kept, not
 367        just the base pack. Defaults to zero. Common unit suffixes of
 368        'k', 'm', or 'g' are supported.
 369+
 370Note that if the number of kept packs is more than gc.autoPackLimit,
 371this configuration variable is ignored, all packs except the base pack
 372will be repacked. After this the number of packs should go below
 373gc.autoPackLimit and gc.bigPackThreshold should be respected again.
 374
 375gc.writeCommitGraph::
 376        If true, then gc will rewrite the commit-graph file when
 377        linkgit:git-gc[1] is run. When using linkgit:git-gc[1]
 378        '--auto' the commit-graph will be updated if housekeeping is
 379        required. Default is false. See linkgit:git-commit-graph[1]
 380        for details.
 381
 382gc.logExpiry::
 383        If the file gc.log exists, then `git gc --auto` will print
 384        its content and exit with status zero instead of running
 385        unless that file is more than 'gc.logExpiry' old.  Default is
 386        "1.day".  See `gc.pruneExpire` for more ways to specify its
 387        value.
 388
 389gc.packRefs::
 390        Running `git pack-refs` in a repository renders it
 391        unclonable by Git versions prior to 1.5.1.2 over dumb
 392        transports such as HTTP.  This variable determines whether
 393        'git gc' runs `git pack-refs`. This can be set to `notbare`
 394        to enable it within all non-bare repos or it can be set to a
 395        boolean value.  The default is `true`.
 396
 397gc.pruneExpire::
 398        When 'git gc' is run, it will call 'prune --expire 2.weeks.ago'.
 399        Override the grace period with this config variable.  The value
 400        "now" may be used to disable this grace period and always prune
 401        unreachable objects immediately, or "never" may be used to
 402        suppress pruning.  This feature helps prevent corruption when
 403        'git gc' runs concurrently with another process writing to the
 404        repository; see the "NOTES" section of linkgit:git-gc[1].
 405
 406gc.worktreePruneExpire::
 407        When 'git gc' is run, it calls
 408        'git worktree prune --expire 3.months.ago'.
 409        This config variable can be used to set a different grace
 410        period. The value "now" may be used to disable the grace
 411        period and prune `$GIT_DIR/worktrees` immediately, or "never"
 412        may be used to suppress pruning.
 413
 414gc.reflogExpire::
 415gc.<pattern>.reflogExpire::
 416        'git reflog expire' removes reflog entries older than
 417        this time; defaults to 90 days. The value "now" expires all
 418        entries immediately, and "never" suppresses expiration
 419        altogether. With "<pattern>" (e.g.
 420        "refs/stash") in the middle the setting applies only to
 421        the refs that match the <pattern>.
 422
 423gc.reflogExpireUnreachable::
 424gc.<pattern>.reflogExpireUnreachable::
 425        'git reflog expire' removes reflog entries older than
 426        this time and are not reachable from the current tip;
 427        defaults to 30 days. The value "now" expires all entries
 428        immediately, and "never" suppresses expiration altogether.
 429        With "<pattern>" (e.g. "refs/stash")
 430        in the middle, the setting applies only to the refs that
 431        match the <pattern>.
 432
 433gc.rerereResolved::
 434        Records of conflicted merge you resolved earlier are
 435        kept for this many days when 'git rerere gc' is run.
 436        You can also use more human-readable "1.month.ago", etc.
 437        The default is 60 days.  See linkgit:git-rerere[1].
 438
 439gc.rerereUnresolved::
 440        Records of conflicted merge you have not resolved are
 441        kept for this many days when 'git rerere gc' is run.
 442        You can also use more human-readable "1.month.ago", etc.
 443        The default is 15 days.  See linkgit:git-rerere[1].

 479        other than 'default'.
 480
 481grep.threads::
 482        Number of grep worker threads to use.
 483        See `grep.threads` in linkgit:git-grep[1] for more information.
 484
 485grep.fallbackToNoIndex::
 486        If set to true, fall back to git grep --no-index if git grep
 487        is executed outside of a git repository.  Defaults to false.
 488
 489gpg.program::
 490        Use this custom program instead of "`gpg`" found on `$PATH` when
 491        making or verifying a PGP signature. The program must support the
 492        same command-line interface as GPG, namely, to verify a detached
 493        signature, "`gpg --verify $file - <$signature`" is run, and the
 494        program is expected to signal a good signature by exiting with
 495        code 0, and to generate an ASCII-armored detached signature, the
 496        standard input of "`gpg -bsau $key`" is fed with the contents to be
 497        signed, and the program is expected to send the result to its
 498        standard output.
 499
 500gpg.format::
 501        Specifies which key format to use when signing with `--gpg-sign`.
 502        Default is "openpgp" and another possible value is "x509".
 503
 504gpg.<format>.program::
 505        Use this to customize the program used for the signing format you
 506        chose. (see `gpg.program` and `gpg.format`) `gpg.program` can still
 507        be used as a legacy synonym for `gpg.openpgp.program`. The default
 508        value for `gpg.x509.program` is "gpgsm".
 509
 510include::gui-config.txt[]
 511
 512guitool.<name>.cmd::
 513        Specifies the shell command line to execute when the corresponding item
 514        of the linkgit:git-gui[1] `Tools` menu is invoked. This option is
 515        mandatory for every tool. The command is executed from the root of
 516        the working directory, and in the environment it receives the name of
 517        the tool as `GIT_GUITOOL`, the name of the currently selected file as
 518        'FILENAME', and the name of the current branch as 'CUR_BRANCH' (if
 519        the head is detached, 'CUR_BRANCH' is empty).
 520
 521guitool.<name>.needsFile::
 522        Run the tool only if a diff is selected in the GUI. It guarantees
 523        that 'FILENAME' is not empty.
 524
 525guitool.<name>.noConsole::
 526        Run the command silently, without creating a window to display its
 527        output.
 528
 529guitool.<name>.noRescan::
 530        Don't rescan the working directory for changes after the tool
 531        finishes execution.
 532
 533guitool.<name>.confirm::
 534        Show a confirmation dialog before actually running the tool.
 535
 536guitool.<name>.argPrompt::
 537        Request a string argument from the user, and pass it to the tool
 538        through the `ARGS` environment variable. Since requesting an
 539        argument implies confirmation, the 'confirm' option has no effect
 540        if this is enabled. If the option is set to 'true', 'yes', or '1',
 541        the dialog uses a built-in generic prompt; otherwise the exact
 542        value of the variable is used.
 543
 544guitool.<name>.revPrompt::
 545        Request a single valid revision from the user, and set the
 546        `REVISION` environment variable. In other aspects this option
 547        is similar to 'argPrompt', and can be used together with it.
 548
 549guitool.<name>.revUnmerged::
 550        Show only unmerged branches in the 'revPrompt' subdialog.
 551        This is useful for tools similar to merge or rebase, but not
 552        for things like checkout or reset.
 553
 554guitool.<name>.title::
 555        Specifies the title to use for the prompt dialog. The default
 556        is the tool name.
 557
 558guitool.<name>.prompt::
 559        Specifies the general prompt string to display at the top of
 560        the dialog, before subsections for 'argPrompt' and 'revPrompt'.
 561        The default value includes the actual command.
 562
 563help.browser::
 564        Specify the browser that will be used to display help in the
 565        'web' format. See linkgit:git-help[1].
 566
 567help.format::
 568        Override the default help format used by linkgit:git-help[1].
 569        Values 'man', 'info', 'web' and 'html' are supported. 'man' is
 570        the default. 'web' and 'html' are the same.
 571
 572help.autoCorrect::
 573        Automatically correct and execute mistyped commands after
 574        waiting for the given number of deciseconds (0.1 sec). If more
 575        than one command can be deduced from the entered text, nothing
 576        will be executed.  If the value of this option is negative,
 577        the corrected command will be executed immediately. If the
 578        value is 0 - the command will be just shown but not executed.
 579        This is the default.
 580
 581help.htmlPath::
 582        Specify the path where the HTML documentation resides. File system paths
 583        and URLs are supported. HTML pages will be prefixed with this path when
 584        help is displayed in the 'web' format. This defaults to the documentation
 585        path of your Git installation.
 586
 587http.proxy::
 588        Override the HTTP proxy, normally configured using the 'http_proxy',
 589        'https_proxy', and 'all_proxy' environment variables (see `curl(1)`). In
 590        addition to the syntax understood by curl, it is possible to specify a
 591        proxy string with a user name but no password, in which case git will
 592        attempt to acquire one in the same way it does for other credentials. See
 593        linkgit:gitcredentials[7] for more information. The syntax thus is
 594        '[protocol://][user[:password]@]proxyhost[:port]'. This can be overridden
 595        on a per-remote basis; see remote.<name>.proxy
 596
 597http.proxyAuthMethod::
 598        Set the method with which to authenticate against the HTTP proxy. This
 599        only takes effect if the configured proxy string contains a user name part
 600        (i.e. is of the form 'user@host' or 'user@host:port'). This can be
 601        overridden on a per-remote basis; see `remote.<name>.proxyAuthMethod`.
 602        Both can be overridden by the `GIT_HTTP_PROXY_AUTHMETHOD` environment
 603        variable.  Possible values are:
 604+
 605--
 606* `anyauth` - Automatically pick a suitable authentication method. It is
 607  assumed that the proxy answers an unauthenticated request with a 407
 608  status code and one or more Proxy-authenticate headers with supported
 609  authentication methods. This is the default.
 610* `basic` - HTTP Basic authentication
 611* `digest` - HTTP Digest authentication; this prevents the password from being
 612  transmitted to the proxy in clear text
 613* `negotiate` - GSS-Negotiate authentication (compare the --negotiate option
 614  of `curl(1)`)
 615* `ntlm` - NTLM authentication (compare the --ntlm option of `curl(1)`)
 616--
 617
 618http.emptyAuth::
 619        Attempt authentication without seeking a username or password.  This
 620        can be used to attempt GSS-Negotiate authentication without specifying
 621        a username in the URL, as libcurl normally requires a username for
 622        authentication.
 623
 624http.delegation::
 625        Control GSSAPI credential delegation. The delegation is disabled
 626        by default in libcurl since version 7.21.7. Set parameter to tell
 627        the server what it is allowed to delegate when it comes to user
 628        credentials. Used with GSS/kerberos. Possible values are:
 629+
 630--
 631* `none` - Don't allow any delegation.
 632* `policy` - Delegates if and only if the OK-AS-DELEGATE flag is set in the
 633  Kerberos service ticket, which is a matter of realm policy.
 634* `always` - Unconditionally allow the server to delegate.
 635--
 636
 637
 638http.extraHeader::
 639        Pass an additional HTTP header when communicating with a server.  If
 640        more than one such entry exists, all of them are added as extra
 641        headers.  To allow overriding the settings inherited from the system
 642        config, an empty value will reset the extra headers to the empty list.
 643
 644http.cookieFile::
 645        The pathname of a file containing previously stored cookie lines,
 646        which should be used
 647        in the Git http session, if they match the server. The file format
 648        of the file to read cookies from should be plain HTTP headers or
 649        the Netscape/Mozilla cookie file format (see `curl(1)`).
 650        NOTE that the file specified with http.cookieFile is used only as
 651        input unless http.saveCookies is set.
 652
 653http.saveCookies::
 654        If set, store cookies received during requests to the file specified by
 655        http.cookieFile. Has no effect if http.cookieFile is unset.
 656
 657http.sslVersion::
 658        The SSL version to use when negotiating an SSL connection, if you
 659        want to force the default.  The available and default version
 660        depend on whether libcurl was built against NSS or OpenSSL and the
 661        particular configuration of the crypto library in use. Internally
 662        this sets the 'CURLOPT_SSL_VERSION' option; see the libcurl
 663        documentation for more details on the format of this option and
 664        for the ssl version supported. Actually the possible values of
 665        this option are:
 666
 667        - sslv2
 668        - sslv3
 669        - tlsv1
 670        - tlsv1.0
 671        - tlsv1.1
 672        - tlsv1.2
 673        - tlsv1.3
 674
 675+
 676Can be overridden by the `GIT_SSL_VERSION` environment variable.
 677To force git to use libcurl's default ssl version and ignore any
 678explicit http.sslversion option, set `GIT_SSL_VERSION` to the
 679empty string.
 680
 681http.sslCipherList::
 682  A list of SSL ciphers to use when negotiating an SSL connection.
 683  The available ciphers depend on whether libcurl was built against
 684  NSS or OpenSSL and the particular configuration of the crypto
 685  library in use.  Internally this sets the 'CURLOPT_SSL_CIPHER_LIST'
 686  option; see the libcurl documentation for more details on the format
 687  of this list.
 688+
 689Can be overridden by the `GIT_SSL_CIPHER_LIST` environment variable.
 690To force git to use libcurl's default cipher list and ignore any
 691explicit http.sslCipherList option, set `GIT_SSL_CIPHER_LIST` to the
 692empty string.
 693
 694http.sslVerify::
 695        Whether to verify the SSL certificate when fetching or pushing
 696        over HTTPS. Defaults to true. Can be overridden by the
 697        `GIT_SSL_NO_VERIFY` environment variable.
 698
 699http.sslCert::
 700        File containing the SSL certificate when fetching or pushing
 701        over HTTPS. Can be overridden by the `GIT_SSL_CERT` environment
 702        variable.
 703
 704http.sslKey::
 705        File containing the SSL private key when fetching or pushing
 706        over HTTPS. Can be overridden by the `GIT_SSL_KEY` environment
 707        variable.
 708
 709http.sslCertPasswordProtected::
 710        Enable Git's password prompt for the SSL certificate.  Otherwise
 711        OpenSSL will prompt the user, possibly many times, if the
 712        certificate or private key is encrypted.  Can be overridden by the
 713        `GIT_SSL_CERT_PASSWORD_PROTECTED` environment variable.
 714
 715http.sslCAInfo::
 716        File containing the certificates to verify the peer with when
 717        fetching or pushing over HTTPS. Can be overridden by the
 718        `GIT_SSL_CAINFO` environment variable.
 719
 720http.sslCAPath::
 721        Path containing files with the CA certificates to verify the peer
 722        with when fetching or pushing over HTTPS. Can be overridden
 723        by the `GIT_SSL_CAPATH` environment variable.
 724
 725http.sslBackend::
 726        Name of the SSL backend to use (e.g. "openssl" or "schannel").
 727        This option is ignored if cURL lacks support for choosing the SSL
 728        backend at runtime.
 729
 730http.schannelCheckRevoke::
 731        Used to enforce or disable certificate revocation checks in cURL
 732        when http.sslBackend is set to "schannel". Defaults to `true` if
 733        unset. Only necessary to disable this if Git consistently errors
 734        and the message is about checking the revocation status of a
 735        certificate. This option is ignored if cURL lacks support for
 736        setting the relevant SSL option at runtime.
 737
 738http.schannelUseSSLCAInfo::
 739        As of cURL v7.60.0, the Secure Channel backend can use the
 740        certificate bundle provided via `http.sslCAInfo`, but that would
 741        override the Windows Certificate Store. Since this is not desirable
 742        by default, Git will tell cURL not to use that bundle by default
 743        when the `schannel` backend was configured via `http.sslBackend`,
 744        unless `http.schannelUseSSLCAInfo` overrides this behavior.
 745
 746http.pinnedpubkey::
 747        Public key of the https service. It may either be the filename of
 748        a PEM or DER encoded public key file or a string starting with
 749        'sha256//' followed by the base64 encoded sha256 hash of the
 750        public key. See also libcurl 'CURLOPT_PINNEDPUBLICKEY'. git will
 751        exit with an error if this option is set but not supported by
 752        cURL.
 753
 754http.sslTry::
 755        Attempt to use AUTH SSL/TLS and encrypted data transfers
 756        when connecting via regular FTP protocol. This might be needed
 757        if the FTP server requires it for security reasons or you wish
 758        to connect securely whenever remote FTP server supports it.
 759        Default is false since it might trigger certificate verification
 760        errors on misconfigured servers.
 761
 762http.maxRequests::
 763        How many HTTP requests to launch in parallel. Can be overridden
 764        by the `GIT_HTTP_MAX_REQUESTS` environment variable. Default is 5.
 765
 766http.minSessions::
 767        The number of curl sessions (counted across slots) to be kept across
 768        requests. They will not be ended with curl_easy_cleanup() until
 769        http_cleanup() is invoked. If USE_CURL_MULTI is not defined, this
 770        value will be capped at 1. Defaults to 1.
 771
 772http.postBuffer::
 773        Maximum size in bytes of the buffer used by smart HTTP
 774        transports when POSTing data to the remote system.
 775        For requests larger than this buffer size, HTTP/1.1 and
 776        Transfer-Encoding: chunked is used to avoid creating a
 777        massive pack file locally.  Default is 1 MiB, which is
 778        sufficient for most requests.
 779
 780http.lowSpeedLimit, http.lowSpeedTime::
 781        If the HTTP transfer speed is less than 'http.lowSpeedLimit'
 782        for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
 783        Can be overridden by the `GIT_HTTP_LOW_SPEED_LIMIT` and
 784        `GIT_HTTP_LOW_SPEED_TIME` environment variables.
 785
 786http.noEPSV::
 787        A boolean which disables using of EPSV ftp command by curl.
 788        This can helpful with some "poor" ftp servers which don't
 789        support EPSV mode. Can be overridden by the `GIT_CURL_FTP_NO_EPSV`
 790        environment variable. Default is false (curl will use EPSV).
 791
 792http.userAgent::
 793        The HTTP USER_AGENT string presented to an HTTP server.  The default
 794        value represents the version of the client Git such as git/1.7.1.
 795        This option allows you to override this value to a more common value
 796        such as Mozilla/4.0.  This may be necessary, for instance, if
 797        connecting through a firewall that restricts HTTP connections to a set
 798        of common USER_AGENT strings (but not including those like git/1.7.1).
 799        Can be overridden by the `GIT_HTTP_USER_AGENT` environment variable.
 800
 801http.followRedirects::
 802        Whether git should follow HTTP redirects. If set to `true`, git
 803        will transparently follow any redirect issued by a server it
 804        encounters. If set to `false`, git will treat all redirects as
 805        errors. If set to `initial`, git will follow redirects only for
 806        the initial request to a remote, but not for subsequent
 807        follow-up HTTP requests. Since git uses the redirected URL as
 808        the base for the follow-up requests, this is generally
 809        sufficient. The default is `initial`.
 810
 811http.<url>.*::
 812        Any of the http.* options above can be applied selectively to some URLs.
 813        For a config key to match a URL, each element of the config key is
 814        compared to that of the URL, in the following order:
 815+
 816--
 817. Scheme (e.g., `https` in `https://example.com/`). This field
 818  must match exactly between the config key and the URL.
 819
 820. Host/domain name (e.g., `example.com` in `https://example.com/`).
 821  This field must match between the config key and the URL. It is
 822  possible to specify a `*` as part of the host name to match all subdomains
 823  at this level. `https://*.example.com/` for example would match
 824  `https://foo.example.com/`, but not `https://foo.bar.example.com/`.
 825
 826. Port number (e.g., `8080` in `http://example.com:8080/`).
 827  This field must match exactly between the config key and the URL.
 828  Omitted port numbers are automatically converted to the correct
 829  default for the scheme before matching.
 830
 831. Path (e.g., `repo.git` in `https://example.com/repo.git`). The
 832  path field of the config key must match the path field of the URL
 833  either exactly or as a prefix of slash-delimited path elements.  This means
 834  a config key with path `foo/` matches URL path `foo/bar`.  A prefix can only
 835  match on a slash (`/`) boundary.  Longer matches take precedence (so a config
 836  key with path `foo/bar` is a better match to URL path `foo/bar` than a config
 837  key with just path `foo/`).
 838
 839. User name (e.g., `user` in `https://user@example.com/repo.git`). If
 840  the config key has a user name it must match the user name in the
 841  URL exactly. If the config key does not have a user name, that
 842  config key will match a URL with any user name (including none),
 843  but at a lower precedence than a config key with a user name.
 844--
 845+
 846The list above is ordered by decreasing precedence; a URL that matches
 847a config key's path is preferred to one that matches its user name. For example,
 848if the URL is `https://user@example.com/foo/bar` a config key match of
 849`https://example.com/foo` will be preferred over a config key match of
 850`https://user@example.com`.
 851+
 852All URLs are normalized before attempting any matching (the password part,
 853if embedded in the URL, is always ignored for matching purposes) so that
 854equivalent URLs that are simply spelled differently will match properly.
 855Environment variable settings always override any matches.  The URLs that are
 856matched against are those given directly to Git commands.  This means any URLs
 857visited as a result of a redirection do not participate in matching.
 858
 859ssh.variant::
 860        By default, Git determines the command line arguments to use
 861        based on the basename of the configured SSH command (configured
 862        using the environment variable `GIT_SSH` or `GIT_SSH_COMMAND` or
 863        the config setting `core.sshCommand`). If the basename is
 864        unrecognized, Git will attempt to detect support of OpenSSH
 865        options by first invoking the configured SSH command with the
 866        `-G` (print configuration) option and will subsequently use
 867        OpenSSH options (if that is successful) or no options besides
 868        the host and remote command (if it fails).
 869+
 870The config variable `ssh.variant` can be set to override this detection.
 871Valid values are `ssh` (to use OpenSSH options), `plink`, `putty`,
 872`tortoiseplink`, `simple` (no options except the host and remote command).
 873The default auto-detection can be explicitly requested using the value
 874`auto`.  Any other value is treated as `ssh`.  This setting can also be
 875overridden via the environment variable `GIT_SSH_VARIANT`.
 876+
 877The current command-line parameters used for each variant are as
 878follows:
 879+
 880--
 881
 882* `ssh` - [-p port] [-4] [-6] [-o option] [username@]host command
 883
 884* `simple` - [username@]host command
 885
 886* `plink` or `putty` - [-P port] [-4] [-6] [username@]host command
 887
 888* `tortoiseplink` - [-P port] [-4] [-6] -batch [username@]host command
 889
 890--
 891+
 892Except for the `simple` variant, command-line parameters are likely to
 893change as git gains new features.
 894
 895i18n.commitEncoding::
 896        Character encoding the commit messages are stored in; Git itself
 897        does not care per se, but this information is necessary e.g. when
 898        importing commits from emails or in the gitk graphical history
 899        browser (and possibly at other places in the future or in other
 900        porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.
 901
 902i18n.logOutputEncoding::
 903        Character encoding the commit messages are converted to when
 904        running 'git log' and friends.
 905
 906imap::
 907        The configuration variables in the 'imap' section are described
 908        in linkgit:git-imap-send[1].
 909
 910index.threads::
 911        Specifies the number of threads to spawn when loading the index.
 912        This is meant to reduce index load time on multiprocessor machines.
 913        Specifying 0 or 'true' will cause Git to auto-detect the number of
 914        CPU's and set the number of threads accordingly. Specifying 1 or
 915        'false' will disable multithreading. Defaults to 'true'.
 916
 917index.version::
 918        Specify the version with which new index files should be
 919        initialized.  This does not affect existing repositories.
 920
 921init.templateDir::
 922        Specify the directory from which templates will be copied.
 923        (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].)
 924
 925instaweb.browser::
 926        Specify the program that will be used to browse your working
 927        repository in gitweb. See linkgit:git-instaweb[1].
 928
 929instaweb.httpd::
 930        The HTTP daemon command-line to start gitweb on your working
 931        repository. See linkgit:git-instaweb[1].
 932
 933instaweb.local::
 934        If true the web server started by linkgit:git-instaweb[1] will
 935        be bound to the local IP (127.0.0.1).
 936
 937instaweb.modulePath::
 938        The default module path for linkgit:git-instaweb[1] to use
 939        instead of /usr/lib/apache2/modules.  Only used if httpd
 940        is Apache.
 941
 942instaweb.port::
 943        The port number to bind the gitweb httpd to. See
 944        linkgit:git-instaweb[1].
 945
 946interactive.singleKey::
 947        In interactive commands, allow the user to provide one-letter
 948        input with a single key (i.e., without hitting enter).
 949        Currently this is used by the `--patch` mode of
 950        linkgit:git-add[1], linkgit:git-checkout[1], linkgit:git-commit[1],
 951        linkgit:git-reset[1], and linkgit:git-stash[1]. Note that this
 952        setting is silently ignored if portable keystroke input
 953        is not available; requires the Perl module Term::ReadKey.
 954
 955interactive.diffFilter::
 956        When an interactive command (such as `git add --patch`) shows
 957        a colorized diff, git will pipe the diff through the shell
 958        command defined by this configuration variable. The command may
 959        mark up the diff further for human consumption, provided that it
 960        retains a one-to-one correspondence with the lines in the
 961        original diff. Defaults to disabled (no filtering).
 962
 963log.abbrevCommit::
 964        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
 965        linkgit:git-whatchanged[1] assume `--abbrev-commit`. You may
 966        override this option with `--no-abbrev-commit`.
 967
 968log.date::
 969        Set the default date-time mode for the 'log' command.
 970        Setting a value for log.date is similar to using 'git log''s
 971        `--date` option.  See linkgit:git-log[1] for details.
 972
 973log.decorate::
 974        Print out the ref names of any commits that are shown by the log
 975        command. If 'short' is specified, the ref name prefixes 'refs/heads/',
 976        'refs/tags/' and 'refs/remotes/' will not be printed. If 'full' is
 977        specified, the full ref name (including prefix) will be printed.
 978        If 'auto' is specified, then if the output is going to a terminal,
 979        the ref names are shown as if 'short' were given, otherwise no ref
 980        names are shown. This is the same as the `--decorate` option
 981        of the `git log`.
 982
 983log.follow::
 984        If `true`, `git log` will act as if the `--follow` option was used when
 985        a single <path> is given.  This has the same limitations as `--follow`,
 986        i.e. it cannot be used to follow multiple files and does not work well
 987        on non-linear history.
 988
 989log.graphColors::
 990        A list of colors, separated by commas, that can be used to draw
 991        history lines in `git log --graph`.
 992
 993log.showRoot::
 994        If true, the initial commit will be shown as a big creation event.
 995        This is equivalent to a diff against an empty tree.
 996        Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
 997        normally hide the root commit will now show it. True by default.
 998
 999log.showSignature::
1000        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
1001        linkgit:git-whatchanged[1] assume `--show-signature`.
1002
1003log.mailmap::
1004        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
1005        linkgit:git-whatchanged[1] assume `--use-mailmap`.
1006
1007mailinfo.scissors::
1008        If true, makes linkgit:git-mailinfo[1] (and therefore
1009        linkgit:git-am[1]) act by default as if the --scissors option
1010        was provided on the command-line. When active, this features
1011        removes everything from the message body before a scissors
1012        line (i.e. consisting mainly of ">8", "8<" and "-").
1013
1014mailmap.file::
1015        The location of an augmenting mailmap file. The default
1016        mailmap, located in the root of the repository, is loaded
1017        first, then the mailmap file pointed to by this variable.
1018        The location of the mailmap file may be in a repository
1019        subdirectory, or somewhere outside of the repository itself.
1020        See linkgit:git-shortlog[1] and linkgit:git-blame[1].
1021
1022mailmap.blob::
1023        Like `mailmap.file`, but consider the value as a reference to a
1024        blob in the repository. If both `mailmap.file` and
1025        `mailmap.blob` are given, both are parsed, with entries from
1026        `mailmap.file` taking precedence. In a bare repository, this
1027        defaults to `HEAD:.mailmap`. In a non-bare repository, it
1028        defaults to empty.
1029
1030man.viewer::
1031        Specify the programs that may be used to display help in the
1032        'man' format. See linkgit:git-help[1].
1033
1034man.<tool>.cmd::
1035        Specify the command to invoke the specified man viewer. The
1036        specified command is evaluated in shell with the man page
1037        passed as argument. (See linkgit:git-help[1].)
1038
1039man.<tool>.path::
1040        Override the path for the given tool that may be used to
1041        display help in the 'man' format. See linkgit:git-help[1].
1042
1043include::merge-config.txt[]
1044
1045mergetool.<tool>.path::
1046        Override the path for the given tool.  This is useful in case
1047        your tool is not in the PATH.
1048
1049mergetool.<tool>.cmd::
1050        Specify the command to invoke the specified merge tool.  The
1051        specified command is evaluated in shell with the following
1052        variables available: 'BASE' is the name of a temporary file
1053        containing the common base of the files to be merged, if available;
1054        'LOCAL' is the name of a temporary file containing the contents of
1055        the file on the current branch; 'REMOTE' is the name of a temporary
1056        file containing the contents of the file from the branch being
1057        merged; 'MERGED' contains the name of the file to which the merge
1058        tool should write the results of a successful merge.
1059
1060mergetool.<tool>.trustExitCode::
1061        For a custom merge command, specify whether the exit code of
1062        the merge command can be used to determine whether the merge was
1063        successful.  If this is not set to true then the merge target file
1064        timestamp is checked and the merge assumed to have been successful
1065        if the file has been updated, otherwise the user is prompted to
1066        indicate the success of the merge.
1067
1068mergetool.meld.hasOutput::
1069        Older versions of `meld` do not support the `--output` option.
1070        Git will attempt to detect whether `meld` supports `--output`
1071        by inspecting the output of `meld --help`.  Configuring
1072        `mergetool.meld.hasOutput` will make Git skip these checks and
1073        use the configured value instead.  Setting `mergetool.meld.hasOutput`
1074        to `true` tells Git to unconditionally use the `--output` option,
1075        and `false` avoids using `--output`.
1076
1077mergetool.keepBackup::
1078        After performing a merge, the original file with conflict markers
1079        can be saved as a file with a `.orig` extension.  If this variable
1080        is set to `false` then this file is not preserved.  Defaults to
1081        `true` (i.e. keep the backup files).
1082
1083mergetool.keepTemporaries::
1084        When invoking a custom merge tool, Git uses a set of temporary
1085        files to pass to the tool. If the tool returns an error and this
1086        variable is set to `true`, then these temporary files will be
1087        preserved, otherwise they will be removed after the tool has
1088        exited. Defaults to `false`.
1089
1090mergetool.writeToTemp::
1091        Git writes temporary 'BASE', 'LOCAL', and 'REMOTE' versions of
1092        conflicting files in the worktree by default.  Git will attempt
1093        to use a temporary directory for these files when set `true`.
1094        Defaults to `false`.
1095
1096mergetool.prompt::
1097        Prompt before each invocation of the merge resolution program.
1098
1099notes.mergeStrategy::
1100        Which merge strategy to choose by default when resolving notes
1101        conflicts.  Must be one of `manual`, `ours`, `theirs`, `union`, or
1102        `cat_sort_uniq`.  Defaults to `manual`.  See "NOTES MERGE STRATEGIES"
1103        section of linkgit:git-notes[1] for more information on each strategy.
1104
1105notes.<name>.mergeStrategy::
1106        Which merge strategy to choose when doing a notes merge into
1107        refs/notes/<name>.  This overrides the more general
1108        "notes.mergeStrategy".  See the "NOTES MERGE STRATEGIES" section in
1109        linkgit:git-notes[1] for more information on the available strategies.
1110
1111notes.displayRef::
1112        The (fully qualified) refname from which to show notes when
1113        showing commit messages.  The value of this variable can be set
1114        to a glob, in which case notes from all matching refs will be
1115        shown.  You may also specify this configuration variable
1116        several times.  A warning will be issued for refs that do not
1117        exist, but a glob that does not match any refs is silently
1118        ignored.
1119+
1120This setting can be overridden with the `GIT_NOTES_DISPLAY_REF`
1121environment variable, which must be a colon separated list of refs or
1122globs.
1123+
1124The effective value of "core.notesRef" (possibly overridden by
1125GIT_NOTES_REF) is also implicitly added to the list of refs to be
1126displayed.
1127
1128notes.rewrite.<command>::
1129        When rewriting commits with <command> (currently `amend` or
1130        `rebase`) and this variable is set to `true`, Git
1131        automatically copies your notes from the original to the
1132        rewritten commit.  Defaults to `true`, but see
1133        "notes.rewriteRef" below.
1134
1135notes.rewriteMode::
1136        When copying notes during a rewrite (see the
1137        "notes.rewrite.<command>" option), determines what to do if
1138        the target commit already has a note.  Must be one of
1139        `overwrite`, `concatenate`, `cat_sort_uniq`, or `ignore`.
1140        Defaults to `concatenate`.
1141+
1142This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
1143environment variable.
1144
1145notes.rewriteRef::
1146        When copying notes during a rewrite, specifies the (fully
1147        qualified) ref whose notes should be copied.  The ref may be a
1148        glob, in which case notes in all matching refs will be copied.
1149        You may also specify this configuration several times.
1150+
1151Does not have a default value; you must configure this variable to
1152enable note rewriting.  Set it to `refs/notes/commits` to enable
1153rewriting for the default commit notes.
1154+
1155This setting can be overridden with the `GIT_NOTES_REWRITE_REF`
1156environment variable, which must be a colon separated list of refs or
1157globs.
1158
1159pack.window::
1160        The size of the window used by linkgit:git-pack-objects[1] when no
1161        window size is given on the command line. Defaults to 10.
1162
1163pack.depth::
1164        The maximum delta depth used by linkgit:git-pack-objects[1] when no
1165        maximum depth is given on the command line. Defaults to 50.
1166        Maximum value is 4095.
1167
1168pack.windowMemory::
1169        The maximum size of memory that is consumed by each thread
1170        in linkgit:git-pack-objects[1] for pack window memory when
1171        no limit is given on the command line.  The value can be
1172        suffixed with "k", "m", or "g".  When left unconfigured (or
1173        set explicitly to 0), there will be no limit.
1174
1175pack.compression::
1176        An integer -1..9, indicating the compression level for objects
1177        in a pack file. -1 is the zlib default. 0 means no
1178        compression, and 1..9 are various speed/size tradeoffs, 9 being
1179        slowest.  If not set,  defaults to core.compression.  If that is
1180        not set,  defaults to -1, the zlib default, which is "a default
1181        compromise between speed and compression (currently equivalent
1182        to level 6)."
1183+
1184Note that changing the compression level will not automatically recompress
1185all existing objects. You can force recompression by passing the -F option
1186to linkgit:git-repack[1].
1187
1188pack.island::
1189        An extended regular expression configuring a set of delta
1190        islands. See "DELTA ISLANDS" in linkgit:git-pack-objects[1]
1191        for details.
1192
1193pack.islandCore::
1194        Specify an island name which gets to have its objects be
1195        packed first. This creates a kind of pseudo-pack at the front
1196        of one pack, so that the objects from the specified island are
1197        hopefully faster to copy into any pack that should be served
1198        to a user requesting these objects. In practice this means
1199        that the island specified should likely correspond to what is
1200        the most commonly cloned in the repo. See also "DELTA ISLANDS"
1201        in linkgit:git-pack-objects[1].
1202
1203pack.deltaCacheSize::
1204        The maximum memory in bytes used for caching deltas in
1205        linkgit:git-pack-objects[1] before writing them out to a pack.
1206        This cache is used to speed up the writing object phase by not
1207        having to recompute the final delta result once the best match
1208        for all objects is found.  Repacking large repositories on machines
1209        which are tight with memory might be badly impacted by this though,
1210        especially if this cache pushes the system into swapping.
1211        A value of 0 means no limit. The smallest size of 1 byte may be
1212        used to virtually disable this cache. Defaults to 256 MiB.
1213
1214pack.deltaCacheLimit::
1215        The maximum size of a delta, that is cached in
1216        linkgit:git-pack-objects[1]. This cache is used to speed up the
1217        writing object phase by not having to recompute the final delta
1218        result once the best match for all objects is found.
1219        Defaults to 1000. Maximum value is 65535.
1220
1221pack.threads::
1222        Specifies the number of threads to spawn when searching for best
1223        delta matches.  This requires that linkgit:git-pack-objects[1]
1224        be compiled with pthreads otherwise this option is ignored with a
1225        warning. This is meant to reduce packing time on multiprocessor
1226        machines. The required amount of memory for the delta search window
1227        is however multiplied by the number of threads.
1228        Specifying 0 will cause Git to auto-detect the number of CPU's
1229        and set the number of threads accordingly.
1230
1231pack.indexVersion::
1232        Specify the default pack index version.  Valid values are 1 for
1233        legacy pack index used by Git versions prior to 1.5.2, and 2 for
1234        the new pack index with capabilities for packs larger than 4 GB
1235        as well as proper protection against the repacking of corrupted
1236        packs.  Version 2 is the default.  Note that version 2 is enforced
1237        and this config option ignored whenever the corresponding pack is
1238        larger than 2 GB.
1239+
1240If you have an old Git that does not understand the version 2 `*.idx` file,
1241cloning or fetching over a non native protocol (e.g. "http")
1242that will copy both `*.pack` file and corresponding `*.idx` file from the
1243other side may give you a repository that cannot be accessed with your
1244older version of Git. If the `*.pack` file is smaller than 2 GB, however,
1245you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
1246the `*.idx` file.
1247
1248pack.packSizeLimit::
1249        The maximum size of a pack.  This setting only affects
1250        packing to a file when repacking, i.e. the git:// protocol
1251        is unaffected.  It can be overridden by the `--max-pack-size`
1252        option of linkgit:git-repack[1].  Reaching this limit results
1253        in the creation of multiple packfiles; which in turn prevents
1254        bitmaps from being created.
1255        The minimum size allowed is limited to 1 MiB.
1256        The default is unlimited.
1257        Common unit suffixes of 'k', 'm', or 'g' are
1258        supported.
1259
1260pack.useBitmaps::
1261        When true, git will use pack bitmaps (if available) when packing
1262        to stdout (e.g., during the server side of a fetch). Defaults to
1263        true. You should not generally need to turn this off unless
1264        you are debugging pack bitmaps.
1265
1266pack.writeBitmaps (deprecated)::
1267        This is a deprecated synonym for `repack.writeBitmaps`.
1268
1269pack.writeBitmapHashCache::
1270        When true, git will include a "hash cache" section in the bitmap
1271        index (if one is written). This cache can be used to feed git's
1272        delta heuristics, potentially leading to better deltas between
1273        bitmapped and non-bitmapped objects (e.g., when serving a fetch
1274        between an older, bitmapped pack and objects that have been
1275        pushed since the last gc). The downside is that it consumes 4
1276        bytes per object of disk space, and that JGit's bitmap
1277        implementation does not understand it, causing it to complain if
1278        Git and JGit are used on the same repository. Defaults to false.
1279
1280pager.<cmd>::
1281        If the value is boolean, turns on or off pagination of the
1282        output of a particular Git subcommand when writing to a tty.
1283        Otherwise, turns on pagination for the subcommand using the
1284        pager specified by the value of `pager.<cmd>`.  If `--paginate`
1285        or `--no-pager` is specified on the command line, it takes
1286        precedence over this option.  To disable pagination for all
1287        commands, set `core.pager` or `GIT_PAGER` to `cat`.
1288
1289pretty.<name>::
1290        Alias for a --pretty= format string, as specified in
1291        linkgit:git-log[1]. Any aliases defined here can be used just
1292        as the built-in pretty formats could. For example,
1293        running `git config pretty.changelog "format:* %H %s"`
1294        would cause the invocation `git log --pretty=changelog`
1295        to be equivalent to running `git log "--pretty=format:* %H %s"`.
1296        Note that an alias with the same name as a built-in format
1297        will be silently ignored.
1298
1299protocol.allow::
1300        If set, provide a user defined default policy for all protocols which
1301        don't explicitly have a policy (`protocol.<name>.allow`).  By default,
1302        if unset, known-safe protocols (http, https, git, ssh, file) have a
1303        default policy of `always`, known-dangerous protocols (ext) have a
1304        default policy of `never`, and all other protocols have a default
1305        policy of `user`.  Supported policies:
1306+
1307--
1308
1309* `always` - protocol is always able to be used.
1310
1311* `never` - protocol is never able to be used.
1312
1313* `user` - protocol is only able to be used when `GIT_PROTOCOL_FROM_USER` is
1314  either unset or has a value of 1.  This policy should be used when you want a
1315  protocol to be directly usable by the user but don't want it used by commands which
1316  execute clone/fetch/push commands without user input, e.g. recursive
1317  submodule initialization.
1318
1319--
1320
1321protocol.<name>.allow::
1322        Set a policy to be used by protocol `<name>` with clone/fetch/push
1323        commands. See `protocol.allow` above for the available policies.
1324+
1325The protocol names currently used by git are:
1326+
1327--
1328  - `file`: any local file-based path (including `file://` URLs,
1329    or local paths)
1330
1331  - `git`: the anonymous git protocol over a direct TCP
1332    connection (or proxy, if configured)
1333
1334  - `ssh`: git over ssh (including `host:path` syntax,
1335    `ssh://`, etc).
1336
1337  - `http`: git over http, both "smart http" and "dumb http".
1338    Note that this does _not_ include `https`; if you want to configure
1339    both, you must do so individually.
1340
1341  - any external helpers are named by their protocol (e.g., use
1342    `hg` to allow the `git-remote-hg` helper)
1343--
1344
1345protocol.version::
1346        Experimental. If set, clients will attempt to communicate with a
1347        server using the specified protocol version.  If unset, no
1348        attempt will be made by the client to communicate using a
1349        particular protocol version, this results in protocol version 0
1350        being used.
1351        Supported versions:
1352+
1353--
1354
1355* `0` - the original wire protocol.
1356
1357* `1` - the original wire protocol with the addition of a version string
1358  in the initial response from the server.
1359
1360* `2` - link:technical/protocol-v2.html[wire protocol version 2].

1372remote.pushDefault::
1373        The remote to push to by default.  Overrides
1374        `branch.<name>.remote` for all branches, and is overridden by
1375        `branch.<name>.pushRemote` for specific branches.
1376
1377remote.<name>.url::
1378        The URL of a remote repository.  See linkgit:git-fetch[1] or
1379        linkgit:git-push[1].
1380
1381remote.<name>.pushurl::
1382        The push URL of a remote repository.  See linkgit:git-push[1].
1383
1384remote.<name>.proxy::
1385        For remotes that require curl (http, https and ftp), the URL to
1386        the proxy to use for that remote.  Set to the empty string to
1387        disable proxying for that remote.
1388
1389remote.<name>.proxyAuthMethod::
1390        For remotes that require curl (http, https and ftp), the method to use for
1391        authenticating against the proxy in use (probably set in
1392        `remote.<name>.proxy`). See `http.proxyAuthMethod`.
1393
1394remote.<name>.fetch::
1395        The default set of "refspec" for linkgit:git-fetch[1]. See
1396        linkgit:git-fetch[1].
1397
1398remote.<name>.push::
1399        The default set of "refspec" for linkgit:git-push[1]. See
1400        linkgit:git-push[1].
1401
1402remote.<name>.mirror::
1403        If true, pushing to this remote will automatically behave
1404        as if the `--mirror` option was given on the command line.
1405
1406remote.<name>.skipDefaultUpdate::
1407        If true, this remote will be skipped by default when updating
1408        using linkgit:git-fetch[1] or the `update` subcommand of
1409        linkgit:git-remote[1].
1410
1411remote.<name>.skipFetchAll::
1412        If true, this remote will be skipped by default when updating
1413        using linkgit:git-fetch[1] or the `update` subcommand of
1414        linkgit:git-remote[1].
1415
1416remote.<name>.receivepack::
1417        The default program to execute on the remote side when pushing.  See
1418        option --receive-pack of linkgit:git-push[1].
1419
1420remote.<name>.uploadpack::
1421        The default program to execute on the remote side when fetching.  See
1422        option --upload-pack of linkgit:git-fetch-pack[1].
1423
1424remote.<name>.tagOpt::
1425        Setting this value to --no-tags disables automatic tag following when
1426        fetching from remote <name>. Setting it to --tags will fetch every
1427        tag from remote <name>, even if they are not reachable from remote
1428        branch heads. Passing these flags directly to linkgit:git-fetch[1] can
1429        override this setting. See options --tags and --no-tags of
1430        linkgit:git-fetch[1].
1431
1432remote.<name>.vcs::
1433        Setting this to a value <vcs> will cause Git to interact with
1434        the remote with the git-remote-<vcs> helper.
1435
1436remote.<name>.prune::
1437        When set to true, fetching from this remote by default will also
1438        remove any remote-tracking references that no longer exist on the
1439        remote (as if the `--prune` option was given on the command line).
1440        Overrides `fetch.prune` settings, if any.
1441
1442remote.<name>.pruneTags::
1443        When set to true, fetching from this remote by default will also
1444        remove any local tags that no longer exist on the remote if pruning
1445        is activated in general via `remote.<name>.prune`, `fetch.prune` or
1446        `--prune`. Overrides `fetch.pruneTags` settings, if any.
1447+
1448See also `remote.<name>.prune` and the PRUNING section of
1449linkgit:git-fetch[1].
1450
1451remotes.<group>::
1452        The list of remotes which are fetched by "git remote update
1453        <group>".  See linkgit:git-remote[1].
1454
1455repack.useDeltaBaseOffset::
1456        By default, linkgit:git-repack[1] creates packs that use
1457        delta-base offset. If you need to share your repository with
1458        Git older than version 1.4.4, either directly or via a dumb
1459        protocol such as http, then you need to set this option to
1460        "false" and repack. Access from old Git versions over the
1461        native protocol are unaffected by this option.
1462
1463repack.packKeptObjects::
1464        If set to true, makes `git repack` act as if
1465        `--pack-kept-objects` was passed. See linkgit:git-repack[1] for
1466        details. Defaults to `false` normally, but `true` if a bitmap
1467        index is being written (either via `--write-bitmap-index` or
1468        `repack.writeBitmaps`).
1469
1470repack.useDeltaIslands::
1471        If set to true, makes `git repack` act as if `--delta-islands`
1472        was passed. Defaults to `false`.
1473
1474repack.writeBitmaps::
1475        When true, git will write a bitmap index when packing all
1476        objects to disk (e.g., when `git repack -a` is run).  This
1477        index can speed up the "counting objects" phase of subsequent
1478        packs created for clones and fetches, at the cost of some disk
1479        space and extra time spent on the initial repack.  This has
1480        no effect if multiple packfiles are created.
1481        Defaults to false.
1482
1483rerere.autoUpdate::
1484        When set to true, `git-rerere` updates the index with the
1485        resulting contents after it cleanly resolves conflicts using
1486        previously recorded resolution.  Defaults to false.
1487
1488rerere.enabled::
1489        Activate recording of resolved conflicts, so that identical
1490        conflict hunks can be resolved automatically, should they be
1491        encountered again.  By default, linkgit:git-rerere[1] is
1492        enabled if there is an `rr-cache` directory under the
1493        `$GIT_DIR`, e.g. if "rerere" was previously used in the
1494        repository.
1495
1496reset.quiet::
1497        When set to true, 'git reset' will default to the '--quiet' option.
1498
1499include::sendemail-config.txt[]
1500
1501sequence.editor::
1502        Text editor used by `git rebase -i` for editing the rebase instruction file.
1503        The value is meant to be interpreted by the shell when it is used.
1504        It can be overridden by the `GIT_SEQUENCE_EDITOR` environment variable.
1505        When not configured the default commit message editor is used instead.
1506
1507showBranch.default::
1508        The default set of branches for linkgit:git-show-branch[1].
1509        See linkgit:git-show-branch[1].
1510
1511splitIndex.maxPercentChange::
1512        When the split index feature is used, this specifies the
1513        percent of entries the split index can contain compared to the
1514        total number of entries in both the split index and the shared
1515        index before a new shared index is written.
1516        The value should be between 0 and 100. If the value is 0 then
1517        a new shared index is always written, if it is 100 a new
1518        shared index is never written.
1519        By default the value is 20, so a new shared index is written
1520        if the number of entries in the split index would be greater
1521        than 20 percent of the total number of entries.
1522        See linkgit:git-update-index[1].
1523
1524splitIndex.sharedIndexExpire::
1525        When the split index feature is used, shared index files that
1526        were not modified since the time this variable specifies will
1527        be removed when a new shared index file is created. The value
1528        "now" expires all entries immediately, and "never" suppresses
1529        expiration altogether.
1530        The default value is "2.weeks.ago".
1531        Note that a shared index file is considered modified (for the
1532        purpose of expiration) each time a new split-index file is
1533        either created based on it or read from it.
1534        See linkgit:git-update-index[1].
1535
1536status.relativePaths::
1537        By default, linkgit:git-status[1] shows paths relative to the
1538        current directory. Setting this variable to `false` shows paths
1539        relative to the repository root (this was the default for Git
1540        prior to v1.5.4).
1541
1542status.short::
1543        Set to true to enable --short by default in linkgit:git-status[1].
1544        The option --no-short takes precedence over this variable.
1545
1546status.branch::
1547        Set to true to enable --branch by default in linkgit:git-status[1].
1548        The option --no-branch takes precedence over this variable.
1549
1550status.displayCommentPrefix::
1551        If set to true, linkgit:git-status[1] will insert a comment
1552        prefix before each output line (starting with
1553        `core.commentChar`, i.e. `#` by default). This was the
1554        behavior of linkgit:git-status[1] in Git 1.8.4 and previous.
1555        Defaults to false.
1556
1557status.renameLimit::
1558        The number of files to consider when performing rename detection
1559        in linkgit:git-status[1] and linkgit:git-commit[1]. Defaults to
1560        the value of diff.renameLimit.
1561
1562status.renames::
1563        Whether and how Git detects renames in linkgit:git-status[1] and
1564        linkgit:git-commit[1] .  If set to "false", rename detection is
1565        disabled. If set to "true", basic rename detection is enabled.
1566        If set to "copies" or "copy", Git will detect copies, as well.
1567        Defaults to the value of diff.renames.
1568
1569status.showStash::
1570        If set to true, linkgit:git-status[1] will display the number of
1571        entries currently stashed away.
1572        Defaults to false.
1573
1574status.showUntrackedFiles::
1575        By default, linkgit:git-status[1] and linkgit:git-commit[1] show
1576        files which are not currently tracked by Git. Directories which
1577        contain only untracked files, are shown with the directory name
1578        only. Showing untracked files means that Git needs to lstat() all
1579        the files in the whole repository, which might be slow on some
1580        systems. So, this variable controls how the commands displays
1581        the untracked files. Possible values are:
1582+
1583--
1584* `no` - Show no untracked files.
1585* `normal` - Show untracked files and directories.
1586* `all` - Show also individual files in untracked directories.
1587--
1588+
1589If this variable is not specified, it defaults to 'normal'.
1590This variable can be overridden with the -u|--untracked-files option
1591of linkgit:git-status[1] and linkgit:git-commit[1].
1592
1593status.submoduleSummary::
1594        Defaults to false.
1595        If this is set to a non zero number or true (identical to -1 or an
1596        unlimited number), the submodule summary will be enabled and a
1597        summary of commits for modified submodules will be shown (see
1598        --summary-limit option of linkgit:git-submodule[1]). Please note
1599        that the summary output command will be suppressed for all
1600        submodules when `diff.ignoreSubmodules` is set to 'all' or only
1601        for those submodules where `submodule.<name>.ignore=all`. The only
1602        exception to that rule is that status and commit will show staged
1603        submodule changes. To
1604        also view the summary for ignored submodules you can either use
1605        the --ignore-submodules=dirty command-line option or the 'git
1606        submodule summary' command, which shows a similar output but does
1607        not honor these settings.
1608
1609stash.showPatch::
1610        If this is set to true, the `git stash show` command without an
1611        option will show the stash entry in patch form.  Defaults to false.
1612        See description of 'show' command in linkgit:git-stash[1].
1613
1614stash.showStat::
1615        If this is set to true, the `git stash show` command without an
1616        option will show diffstat of the stash entry.  Defaults to true.
1617        See description of 'show' command in linkgit:git-stash[1].
1618
1619include::submodule-config.txt[]
1620
1621tag.forceSignAnnotated::
1622        A boolean to specify whether annotated tags created should be GPG signed.
1623        If `--annotate` is specified on the command line, it takes
1624        precedence over this option.
1625
1626tag.sort::
1627        This variable controls the sort ordering of tags when displayed by
1628        linkgit:git-tag[1]. Without the "--sort=<value>" option provided, the
1629        value of this variable will be used as the default.
1630
1631tar.umask::
1632        This variable can be used to restrict the permission bits of
1633        tar archive entries.  The default is 0002, which turns off the
1634        world write bit.  The special value "user" indicates that the
1635        archiving user's umask will be used instead.  See umask(2) and
1636        linkgit:git-archive[1].
1637
1638transfer.fsckObjects::
1639        When `fetch.fsckObjects` or `receive.fsckObjects` are
1640        not set, the value of this variable is used instead.
1641        Defaults to false.
1642+
1643When set, the fetch or receive will abort in the case of a malformed
1644object or a link to a nonexistent object. In addition, various other
1645issues are checked for, including legacy issues (see `fsck.<msg-id>`),
1646and potential security issues like the existence of a `.GIT` directory
1647or a malicious `.gitmodules` file (see the release notes for v2.2.1
1648and v2.17.1 for details). Other sanity and security checks may be
1649added in future releases.
1650+
1651On the receiving side, failing fsckObjects will make those objects
1652unreachable, see "QUARANTINE ENVIRONMENT" in
1653linkgit:git-receive-pack[1]. On the fetch side, malformed objects will
1654instead be left unreferenced in the repository.
1655+
1656Due to the non-quarantine nature of the `fetch.fsckObjects`
1657implementation it can not be relied upon to leave the object store
1658clean like `receive.fsckObjects` can.
1659+
1660As objects are unpacked they're written to the object store, so there
1661can be cases where malicious objects get introduced even though the
1662"fetch" failed, only to have a subsequent "fetch" succeed because only
1663new incoming objects are checked, not those that have already been
1664written to the object store. That difference in behavior should not be
1665relied upon. In the future, such objects may be quarantined for
1666"fetch" as well.
1667+
1668For now, the paranoid need to find some way to emulate the quarantine
1669environment if they'd like the same protection as "push". E.g. in the
1670case of an internal mirror do the mirroring in two steps, one to fetch
1671the untrusted objects, and then do a second "push" (which will use the
1672quarantine) to another internal repo, and have internal clients
1673consume this pushed-to repository, or embargo internal fetches and
1674only allow them once a full "fsck" has run (and no new fetches have
1675happened in the meantime).
1676
1677transfer.hideRefs::
1678        String(s) `receive-pack` and `upload-pack` use to decide which
1679        refs to omit from their initial advertisements.  Use more than
1680        one definition to specify multiple prefix strings. A ref that is
1681        under the hierarchies listed in the value of this variable is
1682        excluded, and is hidden when responding to `git push` or `git
1683        fetch`.  See `receive.hideRefs` and `uploadpack.hideRefs` for
1684        program-specific versions of this config.
1685+
1686You may also include a `!` in front of the ref name to negate the entry,
1687explicitly exposing it, even if an earlier entry marked it as hidden.
1688If you have multiple hideRefs values, later entries override earlier ones
1689(and entries in more-specific config files override less-specific ones).
1690+
1691If a namespace is in use, the namespace prefix is stripped from each
1692reference before it is matched against `transfer.hiderefs` patterns.
1693For example, if `refs/heads/master` is specified in `transfer.hideRefs` and
1694the current namespace is `foo`, then `refs/namespaces/foo/refs/heads/master`
1695is omitted from the advertisements but `refs/heads/master` and
1696`refs/namespaces/bar/refs/heads/master` are still advertised as so-called
1697"have" lines. In order to match refs before stripping, add a `^` in front of
1698the ref name. If you combine `!` and `^`, `!` must be specified first.
1699+
1700Even if you hide refs, a client may still be able to steal the target
1701objects via the techniques described in the "SECURITY" section of the
1702linkgit:gitnamespaces[7] man page; it's best to keep private data in a
1703separate repository.
1704
1705transfer.unpackLimit::
1706        When `fetch.unpackLimit` or `receive.unpackLimit` are
1707        not set, the value of this variable is used instead.
1708        The default value is 100.
1709
1710uploadarchive.allowUnreachable::
1711        If true, allow clients to use `git archive --remote` to request
1712        any tree, whether reachable from the ref tips or not. See the
1713        discussion in the "SECURITY" section of
1714        linkgit:git-upload-archive[1] for more details. Defaults to
1715        `false`.
1716
1717uploadpack.hideRefs::
1718        This variable is the same as `transfer.hideRefs`, but applies
1719        only to `upload-pack` (and so affects only fetches, not pushes).
1720        An attempt to fetch a hidden ref by `git fetch` will fail.  See
1721        also `uploadpack.allowTipSHA1InWant`.
1722
1723uploadpack.allowTipSHA1InWant::
1724        When `uploadpack.hideRefs` is in effect, allow `upload-pack`
1725        to accept a fetch request that asks for an object at the tip
1726        of a hidden ref (by default, such a request is rejected).
1727        See also `uploadpack.hideRefs`.  Even if this is false, a client
1728        may be able to steal objects via the techniques described in the
1729        "SECURITY" section of the linkgit:gitnamespaces[7] man page; it's
1730        best to keep private data in a separate repository.
1731
1732uploadpack.allowReachableSHA1InWant::
1733        Allow `upload-pack` to accept a fetch request that asks for an
1734        object that is reachable from any ref tip. However, note that
1735        calculating object reachability is computationally expensive.
1736        Defaults to `false`.  Even if this is false, a client may be able
1737        to steal objects via the techniques described in the "SECURITY"
1738        section of the linkgit:gitnamespaces[7] man page; it's best to
1739        keep private data in a separate repository.
1740
1741uploadpack.allowAnySHA1InWant::
1742        Allow `upload-pack` to accept a fetch request that asks for any
1743        object at all.
1744        Defaults to `false`.
1745
1746uploadpack.keepAlive::
1747        When `upload-pack` has started `pack-objects`, there may be a
1748        quiet period while `pack-objects` prepares the pack. Normally
1749        it would output progress information, but if `--quiet` was used
1750        for the fetch, `pack-objects` will output nothing at all until
1751        the pack data begins. Some clients and networks may consider
1752        the server to be hung and give up. Setting this option instructs
1753        `upload-pack` to send an empty keepalive packet every
1754        `uploadpack.keepAlive` seconds. Setting this option to 0
1755        disables keepalive packets entirely. The default is 5 seconds.
1756
1757uploadpack.packObjectsHook::
1758        If this option is set, when `upload-pack` would run
1759        `git pack-objects` to create a packfile for a client, it will
1760        run this shell command instead.  The `pack-objects` command and
1761        arguments it _would_ have run (including the `git pack-objects`
1762        at the beginning) are appended to the shell command. The stdin
1763        and stdout of the hook are treated as if `pack-objects` itself
1764        was run. I.e., `upload-pack` will feed input intended for
1765        `pack-objects` to the hook, and expects a completed packfile on
1766        stdout.
1767+
1768Note that this configuration variable is ignored if it is seen in the
1769repository-level config (this is a safety measure against fetching from
1770untrusted repositories).
1771
1772uploadpack.allowFilter::
1773        If this option is set, `upload-pack` will support partial
1774        clone and partial fetch object filtering.
1775
1776uploadpack.allowRefInWant::
1777        If this option is set, `upload-pack` will support the `ref-in-want`
1778        feature of the protocol version 2 `fetch` command.  This feature
1779        is intended for the benefit of load-balanced servers which may
1780        not have the same view of what OIDs their refs point to due to
1781        replication delay.
1782
1783url.<base>.insteadOf::
1784        Any URL that starts with this value will be rewritten to
1785        start, instead, with <base>. In cases where some site serves a
1786        large number of repositories, and serves them with multiple
1787        access methods, and some users need to use different access
1788        methods, this feature allows people to specify any of the
1789        equivalent URLs and have Git automatically rewrite the URL to
1790        the best alternative for the particular user, even for a
1791        never-before-seen repository on the site.  When more than one
1792        insteadOf strings match a given URL, the longest match is used.
1793+
1794Note that any protocol restrictions will be applied to the rewritten
1795URL. If the rewrite changes the URL to use a custom protocol or remote
1796helper, you may need to adjust the `protocol.*.allow` config to permit
1797the request.  In particular, protocols you expect to use for submodules
1798must be set to `always` rather than the default of `user`. See the
1799description of `protocol.allow` above.
1800
1801url.<base>.pushInsteadOf::
1802        Any URL that starts with this value will not be pushed to;
1803        instead, it will be rewritten to start with <base>, and the
1804        resulting URL will be pushed to. In cases where some site serves
1805        a large number of repositories, and serves them with multiple
1806        access methods, some of which do not allow push, this feature
1807        allows people to specify a pull-only URL and have Git
1808        automatically use an appropriate URL to push, even for a
1809        never-before-seen repository on the site.  When more than one
1810        pushInsteadOf strings match a given URL, the longest match is
1811        used.  If a remote has an explicit pushurl, Git will ignore this
1812        setting for that remote.
1813
1814user.email::
1815        Your email address to be recorded in any newly created commits.
1816        Can be overridden by the `GIT_AUTHOR_EMAIL`, `GIT_COMMITTER_EMAIL`, and
1817        `EMAIL` environment variables.  See linkgit:git-commit-tree[1].
1818
1819user.name::
1820        Your full name to be recorded in any newly created commits.
1821        Can be overridden by the `GIT_AUTHOR_NAME` and `GIT_COMMITTER_NAME`
1822        environment variables.  See linkgit:git-commit-tree[1].
1823
1824user.useConfigOnly::
1825        Instruct Git to avoid trying to guess defaults for `user.email`
1826        and `user.name`, and instead retrieve the values only from the
1827        configuration. For example, if you have multiple email addresses
1828        and would like to use a different one for each repository, then
1829        with this configuration option set to `true` in the global config
1830        along with a name, Git will prompt you to set up an email before
1831        making new commits in a newly cloned repository.
1832        Defaults to `false`.
1833
1834user.signingKey::
1835        If linkgit:git-tag[1] or linkgit:git-commit[1] is not selecting the
1836        key you want it to automatically when creating a signed tag or
1837        commit, you can override the default selection with this variable.
1838        This option is passed unchanged to gpg's --local-user parameter,
1839        so you may specify a key using any method that gpg supports.
1840
1841versionsort.prereleaseSuffix (deprecated)::
1842        Deprecated alias for `versionsort.suffix`.  Ignored if
1843        `versionsort.suffix` is set.
1844
1845versionsort.suffix::
1846        Even when version sort is used in linkgit:git-tag[1], tagnames
1847        with the same base version but different suffixes are still sorted
1848        lexicographically, resulting e.g. in prerelease tags appearing
1849        after the main release (e.g. "1.0-rc1" after "1.0").  This
1850        variable can be specified to determine the sorting order of tags
1851        with different suffixes.
1852+
1853By specifying a single suffix in this variable, any tagname containing
1854that suffix will appear before the corresponding main release.  E.g. if
1855the variable is set to "-rc", then all "1.0-rcX" tags will appear before
1856"1.0".  If specified multiple times, once per suffix, then the order of
1857suffixes in the configuration will determine the sorting order of tagnames
1858with those suffixes.  E.g. if "-pre" appears before "-rc" in the
1859configuration, then all "1.0-preX" tags will be listed before any
1860"1.0-rcX" tags.  The placement of the main release tag relative to tags
1861with various suffixes can be determined by specifying the empty suffix
1862among those other suffixes.  E.g. if the suffixes "-rc", "", "-ck" and
1863"-bfs" appear in the configuration in this order, then all "v4.8-rcX" tags
1864are listed first, followed by "v4.8", then "v4.8-ckX" and finally
1865"v4.8-bfsX".
1866+
1867If more than one suffixes match the same tagname, then that tagname will
1868be sorted according to the suffix which starts at the earliest position in
1869the tagname.  If more than one different matching suffixes start at
1870that earliest position, then that tagname will be sorted according to the
1871longest of those suffixes.
1872The sorting order between different suffixes is undefined if they are
1873in multiple config files.
1874
1875web.browser::
1876        Specify a web browser that may be used by some commands.
1877        Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
1878        may use it.
1879
1880worktree.guessRemote::
1881        With `add`, if no branch argument, and neither of `-b` nor
1882        `-B` nor `--detach` are given, the command defaults to
1883        creating a new branch from HEAD.  If `worktree.guessRemote` is
1884        set to true, `worktree add` tries to find a remote-tracking
1885        branch whose name uniquely matches the new branch name.  If
1886        such a branch exists, it is checked out and set as "upstream"
1887        for the new branch.  If no such match can be found, it falls
1888        back to creating a new branch from the current HEAD.
