Documentation / config.txton commit git-clean: implement partial matching for selection (6083861)
   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

 129Variables
 130~~~~~~~~~
 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" and
 880        "git-clean --interactive"). When false (or `never`), never.
 881        When set to `true` or `auto`, use colors only when the output is
 882        to the terminal. Defaults to false.
 883
 884color.interactive.<slot>::
 885        Use customized color for 'git add --interactive' and 'git clean
 886        --interactive' output. `<slot>` may be `prompt`, `header`, `help`
 887        or `error`, for four distinct types of normal output from
 888        interactive commands.  The values of these variables may be
 889        specified as in color.branch.<slot>.
 890
 891color.pager::
 892        A boolean to enable/disable colored output when the pager is in
 893        use (default is true).
 894
 895color.showbranch::
 896        A boolean to enable/disable color in the output of
 897        linkgit:git-show-branch[1]. May be set to `always`,
 898        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 899        only when the output is to a terminal. Defaults to false.
 900
 901color.status::
 902        A boolean to enable/disable color in the output of
 903        linkgit:git-status[1]. May be set to `always`,
 904        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 905        only when the output is to a terminal. Defaults to false.
 906
 907color.status.<slot>::
 908        Use customized color for status colorization. `<slot>` is
 909        one of `header` (the header text of the status message),
 910        `added` or `updated` (files which are added but not committed),
 911        `changed` (files which are changed but not added in the index),
 912        `untracked` (files which are not tracked by Git),
 913        `branch` (the current branch), or
 914        `nobranch` (the color the 'no branch' warning is shown in, defaulting
 915        to red). The values of these variables may be specified as in
 916        color.branch.<slot>.
 917
 918color.ui::
 919        This variable determines the default value for variables such
 920        as `color.diff` and `color.grep` that control the use of color
 921        per command family. Its scope will expand as more commands learn
 922        configuration to set a default for the `--color` option.  Set it
 923        to `always` if you want all output not intended for machine
 924        consumption to use color, to `true` or `auto` if you want such
 925        output to use color when written to the terminal, or to `false` or
 926        `never` if you prefer Git commands not to use color unless enabled
 927        explicitly with some other configuration or the `--color` option.
 928
 929column.ui::
 930        Specify whether supported commands should output in columns.
 931        This variable consists of a list of tokens separated by spaces
 932        or commas:
 933+
 934--
 935`always`;;
 936        always show in columns
 937`never`;;
 938        never show in columns
 939`auto`;;
 940        show in columns if the output is to the terminal
 941`column`;;
 942        fill columns before rows (default)
 943`row`;;
 944        fill rows before columns
 945`plain`;;
 946        show in one column
 947`dense`;;
 948        make unequal size columns to utilize more space
 949`nodense`;;
 950        make equal size columns
 951--
 952+
 953This option defaults to 'never'.
 954
 955column.branch::
 956        Specify whether to output branch listing in `git branch` in columns.
 957        See `column.ui` for details.
 958
 959column.clean::
 960        Specify the layout when list items in `git clean -i`, which always
 961        shows files and directories in columns. See `column.ui` for details.
 962
 963column.status::
 964        Specify whether to output untracked files in `git status` in columns.
 965        See `column.ui` for details.
 966
 967column.tag::
 968        Specify whether to output tag listing in `git tag` in columns.
 969        See `column.ui` for details.
 970
 971commit.cleanup::
 972        This setting overrides the default of the `--cleanup` option in
 973        `git commit`. See linkgit:git-commit[1] for details. Changing the
 974        default can be useful when you always want to keep lines that begin
 975        with comment character `#` in your log message, in which case you
 976        would do `git config commit.cleanup whitespace` (note that you will
 977        have to remove the help lines that begin with `#` in the commit log
 978        template yourself, if you do this).
 979
 980commit.status::
 981        A boolean to enable/disable inclusion of status information in the
 982        commit message template when using an editor to prepare the commit
 983        message.  Defaults to true.
 984
 985commit.template::
 986        Specify a file to use as the template for new commit messages.
 987        "`~/`" is expanded to the value of `$HOME` and "`~user/`" to the
 988        specified user's home directory.
 989
 990credential.helper::
 991        Specify an external helper to be called when a username or
 992        password credential is needed; the helper may consult external
 993        storage to avoid prompting the user for the credentials. See
 994        linkgit:gitcredentials[7] for details.
 995
 996credential.useHttpPath::
 997        When acquiring credentials, consider the "path" component of an http
 998        or https URL to be important. Defaults to false. See
 999        linkgit:gitcredentials[7] for more information.
1000
1001credential.username::
1002        If no username is set for a network authentication, use this username
1003        by default. See credential.<context>.* below, and
1004        linkgit:gitcredentials[7].
1005
1006credential.<url>.*::
1007        Any of the credential.* options above can be applied selectively to
1008        some credentials. For example "credential.https://example.com.username"
1009        would set the default username only for https connections to
1010        example.com. See linkgit:gitcredentials[7] for details on how URLs are
1011        matched.
1012
1013include::diff-config.txt[]
1014
1015difftool.<tool>.path::
1016        Override the path for the given tool.  This is useful in case
1017        your tool is not in the PATH.
1018
1019difftool.<tool>.cmd::
1020        Specify the command to invoke the specified diff tool.
1021        The specified command is evaluated in shell with the following
1022        variables available:  'LOCAL' is set to the name of the temporary
1023        file containing the contents of the diff pre-image and 'REMOTE'
1024        is set to the name of the temporary file containing the contents
1025        of the diff post-image.
1026
1027difftool.prompt::
1028        Prompt before each invocation of the diff tool.
1029
1030fetch.recurseSubmodules::
1031        This option can be either set to a boolean value or to 'on-demand'.
1032        Setting it to a boolean changes the behavior of fetch and pull to
1033        unconditionally recurse into submodules when set to true or to not
1034        recurse at all when set to false. When set to 'on-demand' (the default
1035        value), fetch and pull will only recurse into a populated submodule
1036        when its superproject retrieves a commit that updates the submodule's
1037        reference.
1038
1039fetch.fsckObjects::
1040        If it is set to true, git-fetch-pack will check all fetched
1041        objects. It will abort in the case of a malformed object or a
1042        broken link. The result of an abort are only dangling objects.
1043        Defaults to false. If not set, the value of `transfer.fsckObjects`
1044        is used instead.
1045
1046fetch.unpackLimit::
1047        If the number of objects fetched over the Git native
1048        transfer is below this
1049        limit, then the objects will be unpacked into loose object
1050        files. However if the number of received objects equals or
1051        exceeds this limit then the received pack will be stored as
1052        a pack, after adding any missing delta bases.  Storing the
1053        pack from a push can make the push operation complete faster,
1054        especially on slow filesystems.  If not set, the value of
1055        `transfer.unpackLimit` is used instead.
1056
1057format.attach::
1058        Enable multipart/mixed attachments as the default for
1059        'format-patch'.  The value can also be a double quoted string
1060        which will enable attachments as the default and set the
1061        value as the boundary.  See the --attach option in
1062        linkgit:git-format-patch[1].
1063
1064format.numbered::
1065        A boolean which can enable or disable sequence numbers in patch
1066        subjects.  It defaults to "auto" which enables it only if there
1067        is more than one patch.  It can be enabled or disabled for all
1068        messages by setting it to "true" or "false".  See --numbered
1069        option in linkgit:git-format-patch[1].
1070
1071format.headers::
1072        Additional email headers to include in a patch to be submitted
1073        by mail.  See linkgit:git-format-patch[1].
1074
1075format.to::
1076format.cc::
1077        Additional recipients to include in a patch to be submitted
1078        by mail.  See the --to and --cc options in
1079        linkgit:git-format-patch[1].
1080
1081format.subjectprefix::
1082        The default for format-patch is to output files with the '[PATCH]'
1083        subject prefix. Use this variable to change that prefix.
1084
1085format.signature::
1086        The default for format-patch is to output a signature containing
1087        the Git version number. Use this variable to change that default.
1088        Set this variable to the empty string ("") to suppress
1089        signature generation.
1090
1091format.suffix::
1092        The default for format-patch is to output files with the suffix
1093        `.patch`. Use this variable to change that suffix (make sure to
1094        include the dot if you want it).
1095
1096format.pretty::
1097        The default pretty format for log/show/whatchanged command,
1098        See linkgit:git-log[1], linkgit:git-show[1],
1099        linkgit:git-whatchanged[1].
1100
1101format.thread::
1102        The default threading style for 'git format-patch'.  Can be
1103        a boolean value, or `shallow` or `deep`.  `shallow` threading
1104        makes every mail a reply to the head of the series,
1105        where the head is chosen from the cover letter, the
1106        `--in-reply-to`, and the first patch mail, in this order.
1107        `deep` threading makes every mail a reply to the previous one.
1108        A true boolean value is the same as `shallow`, and a false
1109        value disables threading.
1110
1111format.signoff::
1112        A boolean value which lets you enable the `-s/--signoff` option of
1113        format-patch by default. *Note:* Adding the Signed-off-by: line to a
1114        patch should be a conscious act and means that you certify you have
1115        the rights to submit this work under the same open source license.
1116        Please see the 'SubmittingPatches' document for further discussion.
1117
1118format.coverLetter::
1119        A boolean that controls whether to generate a cover-letter when
1120        format-patch is invoked, but in addition can be set to "auto", to
1121        generate a cover-letter only when there's more than one patch.
1122
1123filter.<driver>.clean::
1124        The command which is used to convert the content of a worktree
1125        file to a blob upon checkin.  See linkgit:gitattributes[5] for
1126        details.
1127
1128filter.<driver>.smudge::
1129        The command which is used to convert the content of a blob
1130        object to a worktree file upon checkout.  See
1131        linkgit:gitattributes[5] for details.
1132
1133gc.aggressiveWindow::
1134        The window size parameter used in the delta compression
1135        algorithm used by 'git gc --aggressive'.  This defaults
1136        to 250.
1137
1138gc.auto::
1139        When there are approximately more than this many loose
1140        objects in the repository, `git gc --auto` will pack them.
1141        Some Porcelain commands use this command to perform a
1142        light-weight garbage collection from time to time.  The
1143        default value is 6700.  Setting this to 0 disables it.
1144
1145gc.autopacklimit::
1146        When there are more than this many packs that are not
1147        marked with `*.keep` file in the repository, `git gc
1148        --auto` consolidates them into one larger pack.  The
1149        default value is 50.  Setting this to 0 disables it.
1150
1151gc.packrefs::
1152        Running `git pack-refs` in a repository renders it
1153        unclonable by Git versions prior to 1.5.1.2 over dumb
1154        transports such as HTTP.  This variable determines whether
1155        'git gc' runs `git pack-refs`. This can be set to `notbare`
1156        to enable it within all non-bare repos or it can be set to a
1157        boolean value.  The default is `true`.
1158
1159gc.pruneexpire::
1160        When 'git gc' is run, it will call 'prune --expire 2.weeks.ago'.
1161        Override the grace period with this config variable.  The value
1162        "now" may be used to disable this  grace period and always prune
1163        unreachable objects immediately.
1164
1165gc.reflogexpire::
1166gc.<pattern>.reflogexpire::
1167        'git reflog expire' removes reflog entries older than
1168        this time; defaults to 90 days.  With "<pattern>" (e.g.
1169        "refs/stash") in the middle the setting applies only to
1170        the refs that match the <pattern>.
1171
1172gc.reflogexpireunreachable::
1173gc.<ref>.reflogexpireunreachable::
1174        'git reflog expire' removes reflog entries older than
1175        this time and are not reachable from the current tip;
1176        defaults to 30 days.  With "<pattern>" (e.g. "refs/stash")
1177        in the middle, the setting applies only to the refs that
1178        match the <pattern>.
1179
1180gc.rerereresolved::
1181        Records of conflicted merge you resolved earlier are
1182        kept for this many days when 'git rerere gc' is run.
1183        The default is 60 days.  See linkgit:git-rerere[1].
1184
1185gc.rerereunresolved::
1186        Records of conflicted merge you have not resolved are
1187        kept for this many days when 'git rerere gc' is run.
1188        The default is 15 days.  See linkgit:git-rerere[1].
1189
1190gitcvs.commitmsgannotation::
1191        Append this string to each commit message. Set to empty string
1192        to disable this feature. Defaults to "via git-CVS emulator".
1193
1194gitcvs.enabled::
1195        Whether the CVS server interface is enabled for this repository.
1196        See linkgit:git-cvsserver[1].
1197
1198gitcvs.logfile::
1199        Path to a log file where the CVS server interface well... logs
1200        various stuff. See linkgit:git-cvsserver[1].
1201
1202gitcvs.usecrlfattr::
1203        If true, the server will look up the end-of-line conversion
1204        attributes for files to determine the '-k' modes to use. If
1205        the attributes force Git to treat a file as text,
1206        the '-k' mode will be left blank so CVS clients will
1207        treat it as text. If they suppress text conversion, the file
1208        will be set with '-kb' mode, which suppresses any newline munging
1209        the client might otherwise do. If the attributes do not allow
1210        the file type to be determined, then 'gitcvs.allbinary' is
1211        used. See linkgit:gitattributes[5].
1212
1213gitcvs.allbinary::
1214        This is used if 'gitcvs.usecrlfattr' does not resolve
1215        the correct '-kb' mode to use. If true, all
1216        unresolved files are sent to the client in
1217        mode '-kb'. This causes the client to treat them
1218        as binary files, which suppresses any newline munging it
1219        otherwise might do. Alternatively, if it is set to "guess",
1220        then the contents of the file are examined to decide if
1221        it is binary, similar to 'core.autocrlf'.
1222
1223gitcvs.dbname::
1224        Database used by git-cvsserver to cache revision information
1225        derived from the Git repository. The exact meaning depends on the
1226        used database driver, for SQLite (which is the default driver) this
1227        is a filename. Supports variable substitution (see
1228        linkgit:git-cvsserver[1] for details). May not contain semicolons (`;`).
1229        Default: '%Ggitcvs.%m.sqlite'
1230
1231gitcvs.dbdriver::
1232        Used Perl DBI driver. You can specify any available driver
1233        for this here, but it might not work. git-cvsserver is tested
1234        with 'DBD::SQLite', reported to work with 'DBD::Pg', and
1235        reported *not* to work with 'DBD::mysql'. Experimental feature.
1236        May not contain double colons (`:`). Default: 'SQLite'.
1237        See linkgit:git-cvsserver[1].
1238
1239gitcvs.dbuser, gitcvs.dbpass::
1240        Database user and password. Only useful if setting 'gitcvs.dbdriver',
1241        since SQLite has no concept of database users and/or passwords.
1242        'gitcvs.dbuser' supports variable substitution (see
1243        linkgit:git-cvsserver[1] for details).
1244
1245gitcvs.dbTableNamePrefix::
1246        Database table name prefix.  Prepended to the names of any
1247        database tables used, allowing a single database to be used
1248        for several repositories.  Supports variable substitution (see
1249        linkgit:git-cvsserver[1] for details).  Any non-alphabetic
1250        characters will be replaced with underscores.
1251
1252All gitcvs variables except for 'gitcvs.usecrlfattr' and
1253'gitcvs.allbinary' can also be specified as
1254'gitcvs.<access_method>.<varname>' (where 'access_method'
1255is one of "ext" and "pserver") to make them apply only for the given
1256access method.

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

2062        Deprecated alias for 'sendemail.signedoffbycc'.
2063
2064showbranch.default::
2065        The default set of branches for linkgit:git-show-branch[1].
2066        See linkgit:git-show-branch[1].
2067
2068status.relativePaths::
2069        By default, linkgit:git-status[1] shows paths relative to the
2070        current directory. Setting this variable to `false` shows paths
2071        relative to the repository root (this was the default for Git
2072        prior to v1.5.4).
2073
2074status.showUntrackedFiles::
2075        By default, linkgit:git-status[1] and linkgit:git-commit[1] show
2076        files which are not currently tracked by Git. Directories which
2077        contain only untracked files, are shown with the directory name
2078        only. Showing untracked files means that Git needs to lstat() all
2079        all the files in the whole repository, which might be slow on some
2080        systems. So, this variable controls how the commands displays
2081        the untracked files. Possible values are:
2082+
2083--
2084* `no` - Show no untracked files.
2085* `normal` - Show untracked files and directories.
2086* `all` - Show also individual files in untracked directories.
2087--
2088+
2089If this variable is not specified, it defaults to 'normal'.
2090This variable can be overridden with the -u|--untracked-files option
2091of linkgit:git-status[1] and linkgit:git-commit[1].
2092
2093status.submodulesummary::
2094        Defaults to false.
2095        If this is set to a non zero number or true (identical to -1 or an
2096        unlimited number), the submodule summary will be enabled and a
2097        summary of commits for modified submodules will be shown (see
2098        --summary-limit option of linkgit:git-submodule[1]).
2099
2100submodule.<name>.path::
2101submodule.<name>.url::
2102submodule.<name>.update::
2103        The path within this project, URL, and the updating strategy
2104        for a submodule.  These variables are initially populated
2105        by 'git submodule init'; edit them to override the
2106        URL and other values found in the `.gitmodules` file.  See
2107        linkgit:git-submodule[1] and linkgit:gitmodules[5] for details.
2108
2109submodule.<name>.branch::
2110        The remote branch name for a submodule, used by `git submodule
2111        update --remote`.  Set this option to override the value found in
2112        the `.gitmodules` file.  See linkgit:git-submodule[1] and
2113        linkgit:gitmodules[5] for details.
2114
2115submodule.<name>.fetchRecurseSubmodules::
2116        This option can be used to control recursive fetching of this
2117        submodule. It can be overridden by using the --[no-]recurse-submodules
2118        command line option to "git fetch" and "git pull".
2119        This setting will override that from in the linkgit:gitmodules[5]
2120        file.
2121
2122submodule.<name>.ignore::
2123        Defines under what circumstances "git status" and the diff family show
2124        a submodule as modified. When set to "all", it will never be considered
2125        modified, "dirty" will ignore all changes to the submodules work tree and
2126        takes only differences between the HEAD of the submodule and the commit
2127        recorded in the superproject into account. "untracked" will additionally
2128        let submodules with modified tracked files in their work tree show up.
2129        Using "none" (the default when this option is not set) also shows
2130        submodules that have untracked files in their work tree as changed.
2131        This setting overrides any setting made in .gitmodules for this submodule,
2132        both settings can be overridden on the command line by using the
2133        "--ignore-submodules" option.
2134
2135tar.umask::
2136        This variable can be used to restrict the permission bits of
2137        tar archive entries.  The default is 0002, which turns off the
2138        world write bit.  The special value "user" indicates that the
2139        archiving user's umask will be used instead.  See umask(2) and
2140        linkgit:git-archive[1].
2141
2142transfer.fsckObjects::
2143        When `fetch.fsckObjects` or `receive.fsckObjects` are
2144        not set, the value of this variable is used instead.
2145        Defaults to false.
2146
2147transfer.hiderefs::
2148        This variable can be used to set both `receive.hiderefs`
2149        and `uploadpack.hiderefs` at the same time to the same
2150        values.  See entries for these other variables.
2151
2152transfer.unpackLimit::
2153        When `fetch.unpackLimit` or `receive.unpackLimit` are
2154        not set, the value of this variable is used instead.
2155        The default value is 100.
2156
2157uploadpack.hiderefs::
2158        String(s) `upload-pack` uses to decide which refs to omit
2159        from its initial advertisement.  Use more than one
2160        definitions to specify multiple prefix strings. A ref that
2161        are under the hierarchies listed on the value of this
2162        variable is excluded, and is hidden from `git ls-remote`,
2163        `git fetch`, etc.  An attempt to fetch a hidden ref by `git
2164        fetch` will fail.  See also `uploadpack.allowtipsha1inwant`.
2165
2166uploadpack.allowtipsha1inwant::
2167        When `uploadpack.hiderefs` is in effect, allow `upload-pack`
2168        to accept a fetch request that asks for an object at the tip
2169        of a hidden ref (by default, such a request is rejected).
2170        see also `uploadpack.hiderefs`.
2171
2172url.<base>.insteadOf::
2173        Any URL that starts with this value will be rewritten to
2174        start, instead, with <base>. In cases where some site serves a
2175        large number of repositories, and serves them with multiple
2176        access methods, and some users need to use different access
2177        methods, this feature allows people to specify any of the
2178        equivalent URLs and have Git automatically rewrite the URL to
2179        the best alternative for the particular user, even for a
2180        never-before-seen repository on the site.  When more than one
2181        insteadOf strings match a given URL, the longest match is used.
2182
2183url.<base>.pushInsteadOf::
2184        Any URL that starts with this value will not be pushed to;
2185        instead, it will be rewritten to start with <base>, and the
2186        resulting URL will be pushed to. In cases where some site serves
2187        a large number of repositories, and serves them with multiple
2188        access methods, some of which do not allow push, this feature
2189        allows people to specify a pull-only URL and have Git
2190        automatically use an appropriate URL to push, even for a
2191        never-before-seen repository on the site.  When more than one
2192        pushInsteadOf strings match a given URL, the longest match is
2193        used.  If a remote has an explicit pushurl, Git will ignore this
2194        setting for that remote.
2195
2196user.email::
2197        Your email address to be recorded in any newly created commits.
2198        Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and
2199        'EMAIL' environment variables.  See linkgit:git-commit-tree[1].
2200
2201user.name::
2202        Your full name to be recorded in any newly created commits.
2203        Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
2204        environment variables.  See linkgit:git-commit-tree[1].
2205
2206user.signingkey::
2207        If linkgit:git-tag[1] is not selecting the key you want it to
2208        automatically when creating a signed tag, you can override the
2209        default selection with this variable.  This option is passed
2210        unchanged to gpg's --local-user parameter, so you may specify a key
2211        using any method that gpg supports.
2212
2213web.browser::
2214        Specify a web browser that may be used by some commands.
2215        Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
2216        may use it.
