   1CONFIGURATION FILE
   2------------------
   3
   4The Git configuration file contains a number of variables that affect
   5the Git commands' behavior. The `.git/config` file in each repository
   6is used to store the configuration for that repository, and
   7`$HOME/.gitconfig` is used to store a per-user configuration as
   8fallback values for the `.git/config` file. The file `/etc/gitconfig`
   9can be used to store a system-wide default configuration.
  10
  11The configuration variables are used by both the Git plumbing
  12and the porcelains. The variables are divided into sections, wherein
  13the fully qualified variable name of the variable itself is the last
  14dot-separated segment and the section name is everything before the last
  15dot. The variable names are case-insensitive, allow only alphanumeric
  16characters and `-`, and must start with an alphabetic character.  Some
  17variables may appear multiple times.
  18
  19Syntax
  20~~~~~~
  21
  22The syntax is fairly flexible and permissive; whitespaces are mostly
  23ignored.  The '#' and ';' characters begin comments to the end of line,
  24blank lines are ignored.
  25
  26The file consists of sections and variables.  A section begins with
  27the name of the section in square brackets and continues until the next
  28section begins.  Section names are not case sensitive.  Only alphanumeric
  29characters, `-` and `.` are allowed in section names.  Each variable
  30must belong to some section, which means that there must be a section
  31header before the first setting of a variable.
  32
  33Sections can be further divided into subsections.  To begin a subsection
  34put its name in double quotes, separated by space from the section name,
  35in the section header, like in the example below:
  36
  37--------
  38        [section "subsection"]
  39
  40--------
  41
  42Subsection names are case sensitive and can contain any characters except
  43newline (doublequote `"` and backslash have to be escaped as `\"` and `\\`,
  44respectively).  Section headers cannot span multiple
  45lines.  Variables may belong directly to a section or to a given subsection.
  46You can have `[section]` if you have `[section "subsection"]`, but you
  47don't need to.
  48
  49There is also a deprecated `[section.subsection]` syntax. With this
  50syntax, the subsection name is converted to lower-case and is also
  51compared case sensitively. These subsection names follow the same
  52restrictions as section names.
  53
  54All the other lines (and the remainder of the line after the section
  55header) are recognized as setting variables, in the form
  56'name = value'.  If there is no equal sign on the line, the entire line
  57is taken as 'name' and the variable is recognized as boolean "true".
  58The variable names are case-insensitive, allow only alphanumeric characters
  59and `-`, and must start with an alphabetic character.  There can be more
  60than one value for a given variable; we say then that the variable is
  61multivalued.
  62
  63Leading and trailing whitespace in a variable value is discarded.
  64Internal whitespace within a variable value is retained verbatim.
  65
  66The values following the equals sign in variable assign are all either
  67a string, an integer, or a boolean.  Boolean values may be given as yes/no,
  681/0, true/false or on/off.  Case is not significant in boolean values, when
  69converting value to the canonical form using '--bool' type specifier;
  70'git config' will ensure that the output is "true" or "false".
  71
  72String values may be entirely or partially enclosed in double quotes.
  73You need to enclose variable values in double quotes if you want to
  74preserve leading or trailing whitespace, or if the variable value contains
  75comment characters (i.e. it contains '#' or ';').
  76Double quote `"` and backslash `\` characters in variable values must
  77be escaped: use `\"` for `"` and `\\` for `\`.
  78
  79The following escape sequences (beside `\"` and `\\`) are recognized:
  80`\n` for newline character (NL), `\t` for horizontal tabulation (HT, TAB)
  81and `\b` for backspace (BS).  No other char escape sequence, nor octal
  82char sequences are valid.
  83
  84Variable values ending in a `\` are continued on the next line in the
  85customary UNIX fashion.
  86
  87Some variables may require a special value format.
  88
  89Includes
  90~~~~~~~~
  91
  92You can include one config file from another by setting the special
  93`include.path` variable to the name of the file to be included. The
  94included file is expanded immediately, as if its contents had been
  95found at the location of the include directive. If the value of the
  96`include.path` variable is a relative path, the path is considered to be
  97relative to the configuration file in which the include directive was
  98found. The value of `include.path` is subject to tilde expansion: `~/`
  99is expanded to the value of `$HOME`, and `~user/` to the specified
 100user's home directory. See below for examples.
 101

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

1269
1270grep.lineNumber::
1271        If set to true, enable '-n' option by default.
1272
1273grep.patternType::
1274        Set the default matching behavior. Using a value of 'basic', 'extended',
1275        'fixed', or 'perl' will enable the '--basic-regexp', '--extended-regexp',
1276        '--fixed-strings', or '--perl-regexp' option accordingly, while the
1277        value 'default' will return to the default matching behavior.
1278
1279grep.extendedRegexp::
1280        If set to true, enable '--extended-regexp' option by default. This
1281        option is ignored when the 'grep.patternType' option is set to a value
1282        other than 'default'.
1283
1284gpg.program::
1285        Use this custom program instead of "gpg" found on $PATH when
1286        making or verifying a PGP signature. The program must support the
1287        same command line interface as GPG, namely, to verify a detached
1288        signature, "gpg --verify $file - <$signature" is run, and the
1289        program is expected to signal a good signature by exiting with
1290        code 0, and to generate an ascii-armored detached signature, the
1291        standard input of "gpg -bsau $key" is fed with the contents to be
1292        signed, and the program is expected to send the result to its
1293        standard output.
1294
1295gui.commitmsgwidth::
1296        Defines how wide the commit message window is in the
1297        linkgit:git-gui[1]. "75" is the default.
1298
1299gui.diffcontext::
1300        Specifies how many context lines should be used in calls to diff
1301        made by the linkgit:git-gui[1]. The default is "5".
1302
1303gui.encoding::
1304        Specifies the default encoding to use for displaying of
1305        file contents in linkgit:git-gui[1] and linkgit:gitk[1].
1306        It can be overridden by setting the 'encoding' attribute
1307        for relevant files (see linkgit:gitattributes[5]).
1308        If this option is not set, the tools default to the
1309        locale encoding.
1310
1311gui.matchtrackingbranch::
1312        Determines if new branches created with linkgit:git-gui[1] should
1313        default to tracking remote branches with matching names or
1314        not. Default: "false".
1315
1316gui.newbranchtemplate::
1317        Is used as suggested name when creating new branches using the
1318        linkgit:git-gui[1].
1319
1320gui.pruneduringfetch::
1321        "true" if linkgit:git-gui[1] should prune remote-tracking branches when
1322        performing a fetch. The default value is "false".
1323
1324gui.trustmtime::
1325        Determines if linkgit:git-gui[1] should trust the file modification
1326        timestamp or not. By default the timestamps are not trusted.
1327
1328gui.spellingdictionary::
1329        Specifies the dictionary used for spell checking commit messages in
1330        the linkgit:git-gui[1]. When set to "none" spell checking is turned
1331        off.
1332
1333gui.fastcopyblame::
1334        If true, 'git gui blame' uses `-C` instead of `-C -C` for original
1335        location detection. It makes blame significantly faster on huge
1336        repositories at the expense of less thorough copy detection.
1337
1338gui.copyblamethreshold::
1339        Specifies the threshold to use in 'git gui blame' original location
1340        detection, measured in alphanumeric characters. See the
1341        linkgit:git-blame[1] manual for more information on copy detection.
1342
1343gui.blamehistoryctx::
1344        Specifies the radius of history context in days to show in
1345        linkgit:gitk[1] for the selected commit, when the `Show History
1346        Context` menu item is invoked from 'git gui blame'. If this
1347        variable is set to zero, the whole history is shown.
1348
1349guitool.<name>.cmd::
1350        Specifies the shell command line to execute when the corresponding item
1351        of the linkgit:git-gui[1] `Tools` menu is invoked. This option is
1352        mandatory for every tool. The command is executed from the root of
1353        the working directory, and in the environment it receives the name of
1354        the tool as 'GIT_GUITOOL', the name of the currently selected file as
1355        'FILENAME', and the name of the current branch as 'CUR_BRANCH' (if
1356        the head is detached, 'CUR_BRANCH' is empty).
1357
1358guitool.<name>.needsfile::
1359        Run the tool only if a diff is selected in the GUI. It guarantees
1360        that 'FILENAME' is not empty.
1361
1362guitool.<name>.noconsole::
1363        Run the command silently, without creating a window to display its
1364        output.
1365
1366guitool.<name>.norescan::
1367        Don't rescan the working directory for changes after the tool
1368        finishes execution.
1369
1370guitool.<name>.confirm::
1371        Show a confirmation dialog before actually running the tool.
1372
1373guitool.<name>.argprompt::
1374        Request a string argument from the user, and pass it to the tool
1375        through the 'ARGS' environment variable. Since requesting an
1376        argument implies confirmation, the 'confirm' option has no effect
1377        if this is enabled. If the option is set to 'true', 'yes', or '1',
1378        the dialog uses a built-in generic prompt; otherwise the exact
1379        value of the variable is used.
1380
1381guitool.<name>.revprompt::
1382        Request a single valid revision from the user, and set the
1383        'REVISION' environment variable. In other aspects this option
1384        is similar to 'argprompt', and can be used together with it.
1385
1386guitool.<name>.revunmerged::
1387        Show only unmerged branches in the 'revprompt' subdialog.
1388        This is useful for tools similar to merge or rebase, but not
1389        for things like checkout or reset.
1390
1391guitool.<name>.title::
1392        Specifies the title to use for the prompt dialog. The default
1393        is the tool name.
1394
1395guitool.<name>.prompt::
1396        Specifies the general prompt string to display at the top of
1397        the dialog, before subsections for 'argprompt' and 'revprompt'.
1398        The default value includes the actual command.
1399
1400help.browser::
1401        Specify the browser that will be used to display help in the
1402        'web' format. See linkgit:git-help[1].
1403
1404help.format::
1405        Override the default help format used by linkgit:git-help[1].
1406        Values 'man', 'info', 'web' and 'html' are supported. 'man' is
1407        the default. 'web' and 'html' are the same.
1408
1409help.autocorrect::
1410        Automatically correct and execute mistyped commands after
1411        waiting for the given number of deciseconds (0.1 sec). If more
1412        than one command can be deduced from the entered text, nothing
1413        will be executed.  If the value of this option is negative,
1414        the corrected command will be executed immediately. If the
1415        value is 0 - the command will be just shown but not executed.
1416        This is the default.
1417
1418help.htmlpath::
1419        Specify the path where the HTML documentation resides. File system paths
1420        and URLs are supported. HTML pages will be prefixed with this path when
1421        help is displayed in the 'web' format. This defaults to the documentation
1422        path of your Git installation.
1423
1424http.proxy::
1425        Override the HTTP proxy, normally configured using the 'http_proxy',
1426        'https_proxy', and 'all_proxy' environment variables (see
1427        `curl(1)`).  This can be overridden on a per-remote basis; see
1428        remote.<name>.proxy
1429
1430http.cookiefile::
1431        File containing previously stored cookie lines which should be used
1432        in the Git http session, if they match the server. The file format
1433        of the file to read cookies from should be plain HTTP headers or
1434        the Netscape/Mozilla cookie file format (see linkgit:curl[1]).
1435        NOTE that the file specified with http.cookiefile is only used as
1436        input. No cookies will be stored in the file.
1437
1438http.sslVerify::
1439        Whether to verify the SSL certificate when fetching or pushing
1440        over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
1441        variable.
1442
1443http.sslCert::
1444        File containing the SSL certificate when fetching or pushing
1445        over HTTPS. Can be overridden by the 'GIT_SSL_CERT' environment
1446        variable.
1447
1448http.sslKey::
1449        File containing the SSL private key when fetching or pushing
1450        over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment
1451        variable.
1452
1453http.sslCertPasswordProtected::
1454        Enable Git's password prompt for the SSL certificate.  Otherwise
1455        OpenSSL will prompt the user, possibly many times, if the
1456        certificate or private key is encrypted.  Can be overridden by the
1457        'GIT_SSL_CERT_PASSWORD_PROTECTED' environment variable.
1458
1459http.sslCAInfo::
1460        File containing the certificates to verify the peer with when
1461        fetching or pushing over HTTPS. Can be overridden by the
1462        'GIT_SSL_CAINFO' environment variable.
1463
1464http.sslCAPath::
1465        Path containing files with the CA certificates to verify the peer
1466        with when fetching or pushing over HTTPS. Can be overridden
1467        by the 'GIT_SSL_CAPATH' environment variable.
1468
1469http.sslTry::
1470        Attempt to use AUTH SSL/TLS and encrypted data transfers
1471        when connecting via regular FTP protocol. This might be needed
1472        if the FTP server requires it for security reasons or you wish
1473        to connect securely whenever remote FTP server supports it.
1474        Default is false since it might trigger certificate verification
1475        errors on misconfigured servers.
1476
1477http.maxRequests::
1478        How many HTTP requests to launch in parallel. Can be overridden
1479        by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5.
1480
1481http.minSessions::
1482        The number of curl sessions (counted across slots) to be kept across
1483        requests. They will not be ended with curl_easy_cleanup() until
1484        http_cleanup() is invoked. If USE_CURL_MULTI is not defined, this
1485        value will be capped at 1. Defaults to 1.
1486
1487http.postBuffer::
1488        Maximum size in bytes of the buffer used by smart HTTP
1489        transports when POSTing data to the remote system.
1490        For requests larger than this buffer size, HTTP/1.1 and
1491        Transfer-Encoding: chunked is used to avoid creating a
1492        massive pack file locally.  Default is 1 MiB, which is
1493        sufficient for most requests.
1494
1495http.lowSpeedLimit, http.lowSpeedTime::
1496        If the HTTP transfer speed is less than 'http.lowSpeedLimit'
1497        for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
1498        Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and
1499        'GIT_HTTP_LOW_SPEED_TIME' environment variables.
1500
1501http.noEPSV::
1502        A boolean which disables using of EPSV ftp command by curl.
1503        This can helpful with some "poor" ftp servers which don't
1504        support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
1505        environment variable. Default is false (curl will use EPSV).
1506
1507http.useragent::
1508        The HTTP USER_AGENT string presented to an HTTP server.  The default
1509        value represents the version of the client Git such as git/1.7.1.
1510        This option allows you to override this value to a more common value
1511        such as Mozilla/4.0.  This may be necessary, for instance, if
1512        connecting through a firewall that restricts HTTP connections to a set
1513        of common USER_AGENT strings (but not including those like git/1.7.1).
1514        Can be overridden by the 'GIT_HTTP_USER_AGENT' environment variable.
1515
1516i18n.commitEncoding::
1517        Character encoding the commit messages are stored in; Git itself
1518        does not care per se, but this information is necessary e.g. when
1519        importing commits from emails or in the gitk graphical history
1520        browser (and possibly at other places in the future or in other
1521        porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.
1522
1523i18n.logOutputEncoding::
1524        Character encoding the commit messages are converted to when
1525        running 'git log' and friends.
1526
1527imap::
1528        The configuration variables in the 'imap' section are described
1529        in linkgit:git-imap-send[1].
1530
1531init.templatedir::
1532        Specify the directory from which templates will be copied.
1533        (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].)
1534
1535instaweb.browser::
1536        Specify the program that will be used to browse your working
1537        repository in gitweb. See linkgit:git-instaweb[1].
1538
1539instaweb.httpd::
1540        The HTTP daemon command-line to start gitweb on your working
1541        repository. See linkgit:git-instaweb[1].
1542
1543instaweb.local::
1544        If true the web server started by linkgit:git-instaweb[1] will
1545        be bound to the local IP (127.0.0.1).
1546
1547instaweb.modulepath::
1548        The default module path for linkgit:git-instaweb[1] to use
1549        instead of /usr/lib/apache2/modules.  Only used if httpd
1550        is Apache.
1551
1552instaweb.port::
1553        The port number to bind the gitweb httpd to. See
1554        linkgit:git-instaweb[1].
1555
1556interactive.singlekey::
1557        In interactive commands, allow the user to provide one-letter
1558        input with a single key (i.e., without hitting enter).
1559        Currently this is used by the `--patch` mode of
1560        linkgit:git-add[1], linkgit:git-checkout[1], linkgit:git-commit[1],
1561        linkgit:git-reset[1], and linkgit:git-stash[1]. Note that this
1562        setting is silently ignored if portable keystroke input
1563        is not available.
1564
1565log.abbrevCommit::
1566        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
1567        linkgit:git-whatchanged[1] assume `--abbrev-commit`. You may
1568        override this option with `--no-abbrev-commit`.
1569
1570log.date::
1571        Set the default date-time mode for the 'log' command.
1572        Setting a value for log.date is similar to using 'git log''s
1573        `--date` option.  Possible values are `relative`, `local`,
1574        `default`, `iso`, `rfc`, and `short`; see linkgit:git-log[1]
1575        for details.
1576
1577log.decorate::
1578        Print out the ref names of any commits that are shown by the log
1579        command. If 'short' is specified, the ref name prefixes 'refs/heads/',
1580        'refs/tags/' and 'refs/remotes/' will not be printed. If 'full' is
1581        specified, the full ref name (including prefix) will be printed.
1582        This is the same as the log commands '--decorate' option.
1583
1584log.showroot::
1585        If true, the initial commit will be shown as a big creation event.
1586        This is equivalent to a diff against an empty tree.
1587        Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
1588        normally hide the root commit will now show it. True by default.
1589
1590log.mailmap::
1591        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
1592        linkgit:git-whatchanged[1] assume `--use-mailmap`.
1593
1594mailmap.file::
1595        The location of an augmenting mailmap file. The default
1596        mailmap, located in the root of the repository, is loaded
1597        first, then the mailmap file pointed to by this variable.
1598        The location of the mailmap file may be in a repository
1599        subdirectory, or somewhere outside of the repository itself.
1600        See linkgit:git-shortlog[1] and linkgit:git-blame[1].
1601
1602mailmap.blob::
1603        Like `mailmap.file`, but consider the value as a reference to a
1604        blob in the repository. If both `mailmap.file` and
1605        `mailmap.blob` are given, both are parsed, with entries from
1606        `mailmap.file` taking precedence. In a bare repository, this
1607        defaults to `HEAD:.mailmap`. In a non-bare repository, it
1608        defaults to empty.
1609
1610man.viewer::
1611        Specify the programs that may be used to display help in the
1612        'man' format. See linkgit:git-help[1].
1613
1614man.<tool>.cmd::
1615        Specify the command to invoke the specified man viewer. The
1616        specified command is evaluated in shell with the man page
1617        passed as argument. (See linkgit:git-help[1].)
1618
1619man.<tool>.path::
1620        Override the path for the given tool that may be used to
1621        display help in the 'man' format. See linkgit:git-help[1].
1622
1623include::merge-config.txt[]
1624
1625mergetool.<tool>.path::
1626        Override the path for the given tool.  This is useful in case
1627        your tool is not in the PATH.
1628
1629mergetool.<tool>.cmd::
1630        Specify the command to invoke the specified merge tool.  The
1631        specified command is evaluated in shell with the following
1632        variables available: 'BASE' is the name of a temporary file
1633        containing the common base of the files to be merged, if available;
1634        'LOCAL' is the name of a temporary file containing the contents of
1635        the file on the current branch; 'REMOTE' is the name of a temporary
1636        file containing the contents of the file from the branch being
1637        merged; 'MERGED' contains the name of the file to which the merge
1638        tool should write the results of a successful merge.
1639
1640mergetool.<tool>.trustExitCode::
1641        For a custom merge command, specify whether the exit code of
1642        the merge command can be used to determine whether the merge was
1643        successful.  If this is not set to true then the merge target file
1644        timestamp is checked and the merge assumed to have been successful
1645        if the file has been updated, otherwise the user is prompted to
1646        indicate the success of the merge.
1647
1648mergetool.keepBackup::
1649        After performing a merge, the original file with conflict markers
1650        can be saved as a file with a `.orig` extension.  If this variable
1651        is set to `false` then this file is not preserved.  Defaults to
1652        `true` (i.e. keep the backup files).
1653
1654mergetool.keepTemporaries::
1655        When invoking a custom merge tool, Git uses a set of temporary
1656        files to pass to the tool. If the tool returns an error and this
1657        variable is set to `true`, then these temporary files will be
1658        preserved, otherwise they will be removed after the tool has
1659        exited. Defaults to `false`.
1660
1661mergetool.prompt::
1662        Prompt before each invocation of the merge resolution program.
1663
1664notes.displayRef::
1665        The (fully qualified) refname from which to show notes when
1666        showing commit messages.  The value of this variable can be set
1667        to a glob, in which case notes from all matching refs will be
1668        shown.  You may also specify this configuration variable
1669        several times.  A warning will be issued for refs that do not
1670        exist, but a glob that does not match any refs is silently
1671        ignored.
1672+
1673This setting can be overridden with the `GIT_NOTES_DISPLAY_REF`
1674environment variable, which must be a colon separated list of refs or
1675globs.
1676+
1677The effective value of "core.notesRef" (possibly overridden by
1678GIT_NOTES_REF) is also implicitly added to the list of refs to be
1679displayed.
1680
1681notes.rewrite.<command>::
1682        When rewriting commits with <command> (currently `amend` or
1683        `rebase`) and this variable is set to `true`, Git
1684        automatically copies your notes from the original to the
1685        rewritten commit.  Defaults to `true`, but see
1686        "notes.rewriteRef" below.
1687
1688notes.rewriteMode::
1689        When copying notes during a rewrite (see the
1690        "notes.rewrite.<command>" option), determines what to do if
1691        the target commit already has a note.  Must be one of
1692        `overwrite`, `concatenate`, or `ignore`.  Defaults to
1693        `concatenate`.
1694+
1695This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
1696environment variable.
1697
1698notes.rewriteRef::
1699        When copying notes during a rewrite, specifies the (fully
1700        qualified) ref whose notes should be copied.  The ref may be a
1701        glob, in which case notes in all matching refs will be copied.
1702        You may also specify this configuration several times.
1703+
1704Does not have a default value; you must configure this variable to
1705enable note rewriting.  Set it to `refs/notes/commits` to enable
1706rewriting for the default commit notes.
1707+
1708This setting can be overridden with the `GIT_NOTES_REWRITE_REF`
1709environment variable, which must be a colon separated list of refs or
1710globs.
1711
1712pack.window::
1713        The size of the window used by linkgit:git-pack-objects[1] when no
1714        window size is given on the command line. Defaults to 10.
1715
1716pack.depth::
1717        The maximum delta depth used by linkgit:git-pack-objects[1] when no
1718        maximum depth is given on the command line. Defaults to 50.
1719
1720pack.windowMemory::
1721        The window memory size limit used by linkgit:git-pack-objects[1]
1722        when no limit is given on the command line.  The value can be
1723        suffixed with "k", "m", or "g".  Defaults to 0, meaning no
1724        limit.
1725
1726pack.compression::
1727        An integer -1..9, indicating the compression level for objects
1728        in a pack file. -1 is the zlib default. 0 means no
1729        compression, and 1..9 are various speed/size tradeoffs, 9 being
1730        slowest.  If not set,  defaults to core.compression.  If that is
1731        not set,  defaults to -1, the zlib default, which is "a default
1732        compromise between speed and compression (currently equivalent
1733        to level 6)."
1734+
1735Note that changing the compression level will not automatically recompress
1736all existing objects. You can force recompression by passing the -F option
1737to linkgit:git-repack[1].
1738
1739pack.deltaCacheSize::
1740        The maximum memory in bytes used for caching deltas in
1741        linkgit:git-pack-objects[1] before writing them out to a pack.
1742        This cache is used to speed up the writing object phase by not
1743        having to recompute the final delta result once the best match
1744        for all objects is found.  Repacking large repositories on machines
1745        which are tight with memory might be badly impacted by this though,
1746        especially if this cache pushes the system into swapping.
1747        A value of 0 means no limit. The smallest size of 1 byte may be
1748        used to virtually disable this cache. Defaults to 256 MiB.
1749
1750pack.deltaCacheLimit::
1751        The maximum size of a delta, that is cached in
1752        linkgit:git-pack-objects[1]. This cache is used to speed up the
1753        writing object phase by not having to recompute the final delta
1754        result once the best match for all objects is found. Defaults to 1000.
1755
1756pack.threads::
1757        Specifies the number of threads to spawn when searching for best
1758        delta matches.  This requires that linkgit:git-pack-objects[1]
1759        be compiled with pthreads otherwise this option is ignored with a
1760        warning. This is meant to reduce packing time on multiprocessor
1761        machines. The required amount of memory for the delta search window
1762        is however multiplied by the number of threads.
1763        Specifying 0 will cause Git to auto-detect the number of CPU's
1764        and set the number of threads accordingly.
1765
1766pack.indexVersion::
1767        Specify the default pack index version.  Valid values are 1 for
1768        legacy pack index used by Git versions prior to 1.5.2, and 2 for
1769        the new pack index with capabilities for packs larger than 4 GB
1770        as well as proper protection against the repacking of corrupted
1771        packs.  Version 2 is the default.  Note that version 2 is enforced
1772        and this config option ignored whenever the corresponding pack is
1773        larger than 2 GB.
1774+
1775If you have an old Git that does not understand the version 2 `*.idx` file,
1776cloning or fetching over a non native protocol (e.g. "http" and "rsync")
1777that will copy both `*.pack` file and corresponding `*.idx` file from the
1778other side may give you a repository that cannot be accessed with your
1779older version of Git. If the `*.pack` file is smaller than 2 GB, however,
1780you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
1781the `*.idx` file.
1782
1783pack.packSizeLimit::
1784        The maximum size of a pack.  This setting only affects
1785        packing to a file when repacking, i.e. the git:// protocol
1786        is unaffected.  It can be overridden by the `--max-pack-size`
1787        option of linkgit:git-repack[1]. The minimum size allowed is
1788        limited to 1 MiB. The default is unlimited.
1789        Common unit suffixes of 'k', 'm', or 'g' are
1790        supported.
1791
1792pager.<cmd>::
1793        If the value is boolean, turns on or off pagination of the
1794        output of a particular Git subcommand when writing to a tty.
1795        Otherwise, turns on pagination for the subcommand using the
1796        pager specified by the value of `pager.<cmd>`.  If `--paginate`
1797        or `--no-pager` is specified on the command line, it takes
1798        precedence over this option.  To disable pagination for all
1799        commands, set `core.pager` or `GIT_PAGER` to `cat`.
1800
1801pretty.<name>::
1802        Alias for a --pretty= format string, as specified in
1803        linkgit:git-log[1]. Any aliases defined here can be used just
1804        as the built-in pretty formats could. For example,
1805        running `git config pretty.changelog "format:* %H %s"`
1806        would cause the invocation `git log --pretty=changelog`
1807        to be equivalent to running `git log "--pretty=format:* %H %s"`.
1808        Note that an alias with the same name as a built-in format
1809        will be silently ignored.
1810
1811pull.rebase::
1812        When true, rebase branches on top of the fetched branch, instead
1813        of merging the default branch from the default remote when "git
1814        pull" is run. See "branch.<name>.rebase" for setting this on a
1815        per-branch basis.
1816+
1817*NOTE*: this is a possibly dangerous operation; do *not* use
1818it unless you understand the implications (see linkgit:git-rebase[1]
1819for details).
1820
1821pull.octopus::
1822        The default merge strategy to use when pulling multiple branches
1823        at once.
1824
1825pull.twohead::
1826        The default merge strategy to use when pulling a single branch.
1827
1828push.default::
1829        Defines the action `git push` should take if no refspec is given
1830        on the command line, no refspec is configured in the remote, and
1831        no refspec is implied by any of the options given on the command
1832        line. Possible values are:
1833+
1834--
1835* `nothing` - do not push anything.
1836* `matching` - push all branches having the same name in both ends.
1837  This is for those who prepare all the branches into a publishable
1838  shape and then push them out with a single command.  It is not
1839  appropriate for pushing into a repository shared by multiple users,
1840  since locally stalled branches will attempt a non-fast forward push
1841  if other users updated the branch.
1842  +
1843  This is currently the default, but Git 2.0 will change the default
1844  to `simple`.
1845* `upstream` - push the current branch to its upstream branch
1846  (`tracking` is a deprecated synonym for this).
1847  With this, `git push` will update the same remote ref as the one which
1848  is merged by `git pull`, making `push` and `pull` symmetrical.
1849  See "branch.<name>.merge" for how to configure the upstream branch.
1850* `simple` - like `upstream`, but refuses to push if the upstream
1851  branch's name is different from the local one. This is the safest
1852  option and is well-suited for beginners. It will become the default
1853  in Git 2.0.
1854* `current` - push the current branch to a branch of the same name.
1855--
1856+
1857The `simple`, `current` and `upstream` modes are for those who want to
1858push out a single branch after finishing work, even when the other
1859branches are not yet ready to be pushed out. If you are working with
1860other people to push into the same shared repository, you would want
1861to use one of these.
1862
1863rebase.stat::
1864        Whether to show a diffstat of what changed upstream since the last
1865        rebase. False by default.
1866
1867rebase.autosquash::
1868        If set to true enable '--autosquash' option by default.
1869
1870receive.autogc::
1871        By default, git-receive-pack will run "git-gc --auto" after
1872        receiving data from git-push and updating refs.  You can stop
1873        it by setting this variable to false.
1874
1875receive.fsckObjects::
1876        If it is set to true, git-receive-pack will check all received
1877        objects. It will abort in the case of a malformed object or a
1878        broken link. The result of an abort are only dangling objects.
1879        Defaults to false. If not set, the value of `transfer.fsckObjects`
1880        is used instead.
1881
1882receive.unpackLimit::
1883        If the number of objects received in a push is below this
1884        limit then the objects will be unpacked into loose object
1885        files. However if the number of received objects equals or
1886        exceeds this limit then the received pack will be stored as
1887        a pack, after adding any missing delta bases.  Storing the
1888        pack from a push can make the push operation complete faster,
1889        especially on slow filesystems.  If not set, the value of
1890        `transfer.unpackLimit` is used instead.
1891
1892receive.denyDeletes::
1893        If set to true, git-receive-pack will deny a ref update that deletes
1894        the ref. Use this to prevent such a ref deletion via a push.
1895
1896receive.denyDeleteCurrent::
1897        If set to true, git-receive-pack will deny a ref update that
1898        deletes the currently checked out branch of a non-bare repository.
1899
1900receive.denyCurrentBranch::
1901        If set to true or "refuse", git-receive-pack will deny a ref update
1902        to the currently checked out branch of a non-bare repository.
1903        Such a push is potentially dangerous because it brings the HEAD
1904        out of sync with the index and working tree. If set to "warn",
1905        print a warning of such a push to stderr, but allow the push to
1906        proceed. If set to false or "ignore", allow such pushes with no
1907        message. Defaults to "refuse".
1908
1909receive.denyNonFastForwards::
1910        If set to true, git-receive-pack will deny a ref update which is
1911        not a fast-forward. Use this to prevent such an update via a push,
1912        even if that push is forced. This configuration variable is
1913        set when initializing a shared repository.
1914
1915receive.hiderefs::
1916        String(s) `receive-pack` uses to decide which refs to omit
1917        from its initial advertisement.  Use more than one
1918        definitions to specify multiple prefix strings. A ref that
1919        are under the hierarchies listed on the value of this
1920        variable is excluded, and is hidden when responding to `git
1921        push`, and an attempt to update or delete a hidden ref by
1922        `git push` is rejected.
1923
1924receive.updateserverinfo::
1925        If set to true, git-receive-pack will run git-update-server-info
1926        after receiving data from git-push and updating refs.
1927
1928remote.pushdefault::
1929        The remote to push to by default.  Overrides
1930        `branch.<name>.remote` for all branches, and is overridden by
1931        `branch.<name>.pushremote` for specific branches.
1932
1933remote.<name>.url::
1934        The URL of a remote repository.  See linkgit:git-fetch[1] or
1935        linkgit:git-push[1].
1936
1937remote.<name>.pushurl::
1938        The push URL of a remote repository.  See linkgit:git-push[1].
1939
1940remote.<name>.proxy::
1941        For remotes that require curl (http, https and ftp), the URL to
1942        the proxy to use for that remote.  Set to the empty string to
1943        disable proxying for that remote.
1944
1945remote.<name>.fetch::
1946        The default set of "refspec" for linkgit:git-fetch[1]. See
1947        linkgit:git-fetch[1].
1948
1949remote.<name>.push::
1950        The default set of "refspec" for linkgit:git-push[1]. See
1951        linkgit:git-push[1].
1952
1953remote.<name>.mirror::
1954        If true, pushing to this remote will automatically behave
1955        as if the `--mirror` option was given on the command line.
1956
1957remote.<name>.skipDefaultUpdate::
1958        If true, this remote will be skipped by default when updating
1959        using linkgit:git-fetch[1] or the `update` subcommand of
1960        linkgit:git-remote[1].
1961
1962remote.<name>.skipFetchAll::
1963        If true, this remote will be skipped by default when updating
1964        using linkgit:git-fetch[1] or the `update` subcommand of
1965        linkgit:git-remote[1].
1966
1967remote.<name>.receivepack::
1968        The default program to execute on the remote side when pushing.  See
1969        option \--receive-pack of linkgit:git-push[1].
1970
1971remote.<name>.uploadpack::
1972        The default program to execute on the remote side when fetching.  See
1973        option \--upload-pack of linkgit:git-fetch-pack[1].
1974
1975remote.<name>.tagopt::
1976        Setting this value to \--no-tags disables automatic tag following when
1977        fetching from remote <name>. Setting it to \--tags will fetch every
1978        tag from remote <name>, even if they are not reachable from remote
1979        branch heads. Passing these flags directly to linkgit:git-fetch[1] can
1980        override this setting. See options \--tags and \--no-tags of
1981        linkgit:git-fetch[1].
1982
1983remote.<name>.vcs::
1984        Setting this to a value <vcs> will cause Git to interact with
1985        the remote with the git-remote-<vcs> helper.
1986
1987remotes.<group>::
1988        The list of remotes which are fetched by "git remote update
1989        <group>".  See linkgit:git-remote[1].
1990
1991repack.usedeltabaseoffset::
1992        By default, linkgit:git-repack[1] creates packs that use
1993        delta-base offset. If you need to share your repository with
1994        Git older than version 1.4.4, either directly or via a dumb
1995        protocol such as http, then you need to set this option to
1996        "false" and repack. Access from old Git versions over the
1997        native protocol are unaffected by this option.
1998
1999rerere.autoupdate::
2000        When set to true, `git-rerere` updates the index with the
2001        resulting contents after it cleanly resolves conflicts using
2002        previously recorded resolution.  Defaults to false.
2003
2004rerere.enabled::
2005        Activate recording of resolved conflicts, so that identical
2006        conflict hunks can be resolved automatically, should they be
2007        encountered again.  By default, linkgit:git-rerere[1] is
2008        enabled if there is an `rr-cache` directory under the
2009        `$GIT_DIR`, e.g. if "rerere" was previously used in the
2010        repository.
2011
2012sendemail.identity::
2013        A configuration identity. When given, causes values in the
2014        'sendemail.<identity>' subsection to take precedence over
2015        values in the 'sendemail' section. The default identity is
2016        the value of 'sendemail.identity'.
2017
2018sendemail.smtpencryption::
2019        See linkgit:git-send-email[1] for description.  Note that this
2020        setting is not subject to the 'identity' mechanism.
2021
2022sendemail.smtpssl::
2023        Deprecated alias for 'sendemail.smtpencryption = ssl'.
2024
2025sendemail.<identity>.*::
2026        Identity-specific versions of the 'sendemail.*' parameters
2027        found below, taking precedence over those when the this
2028        identity is selected, through command-line or
2029        'sendemail.identity'.

2057        Deprecated alias for 'sendemail.signedoffbycc'.
2058
2059showbranch.default::
2060        The default set of branches for linkgit:git-show-branch[1].
2061        See linkgit:git-show-branch[1].
2062
2063status.relativePaths::
2064        By default, linkgit:git-status[1] shows paths relative to the
2065        current directory. Setting this variable to `false` shows paths
2066        relative to the repository root (this was the default for Git
2067        prior to v1.5.4).
2068
2069status.showUntrackedFiles::
2070        By default, linkgit:git-status[1] and linkgit:git-commit[1] show
2071        files which are not currently tracked by Git. Directories which
2072        contain only untracked files, are shown with the directory name
2073        only. Showing untracked files means that Git needs to lstat() all
2074        all the files in the whole repository, which might be slow on some
2075        systems. So, this variable controls how the commands displays
2076        the untracked files. Possible values are:
2077+
2078--
2079* `no` - Show no untracked files.
2080* `normal` - Show untracked files and directories.
2081* `all` - Show also individual files in untracked directories.
2082--
2083+
2084If this variable is not specified, it defaults to 'normal'.
2085This variable can be overridden with the -u|--untracked-files option
2086of linkgit:git-status[1] and linkgit:git-commit[1].
2087
2088status.submodulesummary::
2089        Defaults to false.
2090        If this is set to a non zero number or true (identical to -1 or an
2091        unlimited number), the submodule summary will be enabled and a
2092        summary of commits for modified submodules will be shown (see
2093        --summary-limit option of linkgit:git-submodule[1]).
2094
2095submodule.<name>.path::
2096submodule.<name>.url::
2097submodule.<name>.update::
2098        The path within this project, URL, and the updating strategy
2099        for a submodule.  These variables are initially populated
2100        by 'git submodule init'; edit them to override the
2101        URL and other values found in the `.gitmodules` file.  See
2102        linkgit:git-submodule[1] and linkgit:gitmodules[5] for details.
2103
2104submodule.<name>.branch::
2105        The remote branch name for a submodule, used by `git submodule
2106        update --remote`.  Set this option to override the value found in
2107        the `.gitmodules` file.  See linkgit:git-submodule[1] and
2108        linkgit:gitmodules[5] for details.
2109
2110submodule.<name>.fetchRecurseSubmodules::
2111        This option can be used to control recursive fetching of this
2112        submodule. It can be overridden by using the --[no-]recurse-submodules
2113        command line option to "git fetch" and "git pull".
2114        This setting will override that from in the linkgit:gitmodules[5]
2115        file.
2116
2117submodule.<name>.ignore::
2118        Defines under what circumstances "git status" and the diff family show
2119        a submodule as modified. When set to "all", it will never be considered
2120        modified, "dirty" will ignore all changes to the submodules work tree and
2121        takes only differences between the HEAD of the submodule and the commit
2122        recorded in the superproject into account. "untracked" will additionally
2123        let submodules with modified tracked files in their work tree show up.
2124        Using "none" (the default when this option is not set) also shows
2125        submodules that have untracked files in their work tree as changed.
2126        This setting overrides any setting made in .gitmodules for this submodule,
2127        both settings can be overridden on the command line by using the
2128        "--ignore-submodules" option.
2129
2130tar.umask::
2131        This variable can be used to restrict the permission bits of
2132        tar archive entries.  The default is 0002, which turns off the
2133        world write bit.  The special value "user" indicates that the
2134        archiving user's umask will be used instead.  See umask(2) and
2135        linkgit:git-archive[1].
2136
2137transfer.fsckObjects::
2138        When `fetch.fsckObjects` or `receive.fsckObjects` are
2139        not set, the value of this variable is used instead.
2140        Defaults to false.
2141
2142transfer.hiderefs::
2143        This variable can be used to set both `receive.hiderefs`
2144        and `uploadpack.hiderefs` at the same time to the same
2145        values.  See entries for these other variables.
2146
2147transfer.unpackLimit::
2148        When `fetch.unpackLimit` or `receive.unpackLimit` are
2149        not set, the value of this variable is used instead.
2150        The default value is 100.
2151
2152uploadpack.hiderefs::
2153        String(s) `upload-pack` uses to decide which refs to omit
2154        from its initial advertisement.  Use more than one
2155        definitions to specify multiple prefix strings. A ref that
2156        are under the hierarchies listed on the value of this
2157        variable is excluded, and is hidden from `git ls-remote`,
2158        `git fetch`, etc.  An attempt to fetch a hidden ref by `git
2159        fetch` will fail.  See also `uploadpack.allowtipsha1inwant`.
2160
2161uploadpack.allowtipsha1inwant::
2162        When `uploadpack.hiderefs` is in effect, allow `upload-pack`
2163        to accept a fetch request that asks for an object at the tip
2164        of a hidden ref (by default, such a request is rejected).
2165        see also `uploadpack.hiderefs`.
2166
2167url.<base>.insteadOf::
2168        Any URL that starts with this value will be rewritten to
2169        start, instead, with <base>. In cases where some site serves a
2170        large number of repositories, and serves them with multiple
2171        access methods, and some users need to use different access
2172        methods, this feature allows people to specify any of the
2173        equivalent URLs and have Git automatically rewrite the URL to
2174        the best alternative for the particular user, even for a
2175        never-before-seen repository on the site.  When more than one
2176        insteadOf strings match a given URL, the longest match is used.
2177
2178url.<base>.pushInsteadOf::
2179        Any URL that starts with this value will not be pushed to;
2180        instead, it will be rewritten to start with <base>, and the
2181        resulting URL will be pushed to. In cases where some site serves
2182        a large number of repositories, and serves them with multiple
2183        access methods, some of which do not allow push, this feature
2184        allows people to specify a pull-only URL and have Git
2185        automatically use an appropriate URL to push, even for a
2186        never-before-seen repository on the site.  When more than one
2187        pushInsteadOf strings match a given URL, the longest match is
2188        used.  If a remote has an explicit pushurl, Git will ignore this
2189        setting for that remote.
2190
2191user.email::
2192        Your email address to be recorded in any newly created commits.
2193        Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and
2194        'EMAIL' environment variables.  See linkgit:git-commit-tree[1].
2195
2196user.name::
2197        Your full name to be recorded in any newly created commits.
2198        Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
2199        environment variables.  See linkgit:git-commit-tree[1].
2200
2201user.signingkey::
2202        If linkgit:git-tag[1] is not selecting the key you want it to
2203        automatically when creating a signed tag, you can override the
2204        default selection with this variable.  This option is passed
2205        unchanged to gpg's --local-user parameter, so you may specify a key
2206        using any method that gpg supports.
2207
2208web.browser::
2209        Specify a web browser that may be used by some commands.
2210        Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
2211        may use it.
