Documentation / config.txton commit pack-objects doc: treat output filename as opaque (40a4f5a)
   1CONFIGURATION FILE
   2------------------
   3
   4The Git configuration file contains a number of variables that affect
   5the Git commands' behavior. The `.git/config` file in each repository
   6is used to store the configuration for that repository, and
   7`$HOME/.gitconfig` is used to store a per-user configuration as
   8fallback values for the `.git/config` file. The file `/etc/gitconfig`
   9can be used to store a system-wide default configuration.
  10
  11The configuration variables are used by both the Git plumbing
  12and the porcelains. The variables are divided into sections, wherein
  13the fully qualified variable name of the variable itself is the last
  14dot-separated segment and the section name is everything before the last
  15dot. The variable names are case-insensitive, allow only alphanumeric
  16characters and `-`, and must start with an alphabetic character.  Some
  17variables may appear multiple times.
  18
  19Syntax
  20~~~~~~
  21
  22The syntax is fairly flexible and permissive; whitespaces are mostly
  23ignored.  The '#' and ';' characters begin comments to the end of line,
  24blank lines are ignored.
  25
  26The file consists of sections and variables.  A section begins with
  27the name of the section in square brackets and continues until the next
  28section begins.  Section names are not case sensitive.  Only alphanumeric
  29characters, `-` and `.` are allowed in section names.  Each variable
  30must belong to some section, which means that there must be a section
  31header before the first setting of a variable.
  32
  33Sections can be further divided into subsections.  To begin a subsection
  34put its name in double quotes, separated by space from the section name,
  35in the section header, like in the example below:
  36
  37--------
  38        [section "subsection"]
  39
  40--------
  41
  42Subsection names are case sensitive and can contain any characters except
  43newline (doublequote `"` and backslash have to be escaped as `\"` and `\\`,
  44respectively).  Section headers cannot span multiple
  45lines.  Variables may belong directly to a section or to a given subsection.
  46You can have `[section]` if you have `[section "subsection"]`, but you
  47don't need to.
  48
  49There is also a deprecated `[section.subsection]` syntax. With this
  50syntax, the subsection name is converted to lower-case and is also
  51compared case sensitively. These subsection names follow the same
  52restrictions as section names.
  53
  54All the other lines (and the remainder of the line after the section
  55header) are recognized as setting variables, in the form
  56'name = value'.  If there is no equal sign on the line, the entire line
  57is taken as 'name' and the variable is recognized as boolean "true".
  58The variable names are case-insensitive, allow only alphanumeric characters
  59and `-`, and must start with an alphabetic character.  There can be more
  60than one value for a given variable; we say then that the variable is
  61multivalued.
  62
  63Leading and trailing whitespace in a variable value is discarded.
  64Internal whitespace within a variable value is retained verbatim.
  65
  66The values following the equals sign in variable assign are all either
  67a string, an integer, or a boolean.  Boolean values may be given as yes/no,
  681/0, true/false or on/off.  Case is not significant in boolean values, when
  69converting value to the canonical form using '--bool' type specifier;
  70'git config' will ensure that the output is "true" or "false".
  71
  72String values may be entirely or partially enclosed in double quotes.
  73You need to enclose variable values in double quotes if you want to
  74preserve leading or trailing whitespace, or if the variable value contains
  75comment characters (i.e. it contains '#' or ';').
  76Double quote `"` and backslash `\` characters in variable values must
  77be escaped: use `\"` for `"` and `\\` for `\`.
  78
  79The following escape sequences (beside `\"` and `\\`) are recognized:
  80`\n` for newline character (NL), `\t` for horizontal tabulation (HT, TAB)
  81and `\b` for backspace (BS).  No other char escape sequence, nor octal
  82char sequences are valid.
  83
  84Variable values ending in a `\` are continued on the next line in the
  85customary UNIX fashion.
  86
  87Some variables may require a special value format.
  88
  89Includes
  90~~~~~~~~
  91
  92You can include one config file from another by setting the special
  93`include.path` variable to the name of the file to be included. The
  94included file is expanded immediately, as if its contents had been
  95found at the location of the include directive. If the value of the
  96`include.path` variable is a relative path, the path is considered to be
  97relative to the configuration file in which the include directive was
  98found. The value of `include.path` is subject to tilde expansion: `~/`
  99is expanded to the value of `$HOME`, and `~user/` to the specified
 100user's home directory. See below for examples.
 101

 131
 132Note that this list is non-comprehensive and not necessarily complete.
 133For command-specific variables, you will find a more detailed description
 134in the appropriate manual page. You will find a description of non-core
 135porcelain configuration variables in the respective porcelain documentation.
 136
 137advice.*::
 138        These variables control various optional help messages designed to
 139        aid new users. All 'advice.*' variables default to 'true', and you
 140        can tell Git that you do not need help by setting these to 'false':
 141+
 142--
 143        pushUpdateRejected::
 144                Set this variable to 'false' if you want to disable
 145                'pushNonFFCurrent', 'pushNonFFDefault',
 146                'pushNonFFMatching', 'pushAlreadyExists',
 147                'pushFetchFirst', and 'pushNeedsForce'
 148                simultaneously.
 149        pushNonFFCurrent::
 150                Advice shown when linkgit:git-push[1] fails due to a
 151                non-fast-forward update to the current branch.
 152        pushNonFFDefault::
 153                Advice to set 'push.default' to 'upstream' or 'current'
 154                when you ran linkgit:git-push[1] and pushed 'matching
 155                refs' by default (i.e. you did not provide an explicit
 156                refspec, and no 'push.default' configuration was set)
 157                and it resulted in a non-fast-forward error.
 158        pushNonFFMatching::
 159                Advice shown when you ran linkgit:git-push[1] and pushed
 160                'matching refs' explicitly (i.e. you used ':', or
 161                specified a refspec that isn't your current branch) and
 162                it resulted in a non-fast-forward error.
 163        pushAlreadyExists::
 164                Shown when linkgit:git-push[1] rejects an update that
 165                does not qualify for fast-forwarding (e.g., a tag.)
 166        pushFetchFirst::
 167                Shown when linkgit:git-push[1] rejects an update that
 168                tries to overwrite a remote ref that points at an
 169                object we do not have.
 170        pushNeedsForce::
 171                Shown when linkgit:git-push[1] rejects an update that
 172                tries to overwrite a remote ref that points at an
 173                object that is not a commit-ish, or make the remote
 174                ref point at an object that is not a commit-ish.
 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.

 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        rmHints::
 203                In case of failure in the output of linkgit:git-rm[1],
 204                show directions on how to proceed from the current state.
 205--
 206
 207core.fileMode::
 208        If false, the executable bit differences between the index and
 209        the working tree are ignored; useful on broken filesystems like FAT.
 210        See linkgit:git-update-index[1].
 211+
 212The default is true, except linkgit:git-clone[1] or linkgit:git-init[1]
 213will probe and set core.fileMode false if appropriate when the
 214repository is created.
 215
 216core.ignorecase::
 217        If true, this option enables various workarounds to enable
 218        Git to work better on filesystems that are not case sensitive,
 219        like FAT. For example, if a directory listing finds
 220        "makefile" when Git expects "Makefile", Git will assume
 221        it is really the same file, and continue to remember it as
 222        "Makefile".
 223+
 224The default is false, except linkgit:git-clone[1] or linkgit:git-init[1]
 225will probe and set core.ignorecase true if appropriate when the repository
 226is created.
 227
 228core.precomposeunicode::
 229        This option is only used by Mac OS implementation of Git.
 230        When core.precomposeunicode=true, Git reverts the unicode decomposition
 231        of filenames done by Mac OS. This is useful when sharing a repository
 232        between Mac OS and Linux or Windows.
 233        (Git for Windows 1.7.10 or higher is needed, or Git under cygwin 1.7).
 234        When false, file names are handled fully transparent by Git,
 235        which is backward compatible with older versions of Git.
 236
 237core.trustctime::
 238        If false, the ctime differences between the index and the
 239        working tree are ignored; useful when the inode change time
 240        is regularly modified by something outside Git (file system
 241        crawlers and some backup systems).
 242        See linkgit:git-update-index[1]. True by default.
 243
 244core.checkstat::
 245        Determines which stat fields to match between the index
 246        and work tree. The user can set this to 'default' or
 247        'minimal'. Default (or explicitly 'default'), is to check
 248        all fields, including the sub-second part of mtime and ctime.
 249
 250core.quotepath::
 251        The commands that output paths (e.g. 'ls-files',
 252        'diff'), when not given the `-z` option, will quote
 253        "unusual" characters in the pathname by enclosing the
 254        pathname in a double-quote pair and with backslashes the
 255        same way strings in C source code are quoted.  If this
 256        variable is set to false, the bytes higher than 0x80 are
 257        not quoted but output as verbatim.  Note that double
 258        quote, backslash and control characters are always
 259        quoted without `-z` regardless of the setting of this
 260        variable.
 261
 262core.eol::
 263        Sets the line ending type to use in the working directory for
 264        files that have the `text` property set.  Alternatives are
 265        'lf', 'crlf' and 'native', which uses the platform's native
 266        line ending.  The default value is `native`.  See
 267        linkgit:gitattributes[5] for more information on end-of-line
 268        conversion.
 269
 270core.safecrlf::
 271        If true, makes Git check if converting `CRLF` is reversible when
 272        end-of-line conversion is active.  Git will verify if a command
 273        modifies a file in the work tree either directly or indirectly.
 274        For example, committing a file followed by checking out the
 275        same file should yield the original file in the work tree.  If
 276        this is not the case for the current setting of
 277        `core.autocrlf`, Git will reject the file.  The variable can
 278        be set to "warn", in which case Git will only warn about an
 279        irreversible conversion but continue the operation.
 280+
 281CRLF conversion bears a slight chance of corrupting data.
 282When it is enabled, Git will convert CRLF to LF during commit and LF to
 283CRLF during checkout.  A file that contains a mixture of LF and
 284CRLF before the commit cannot be recreated by Git.  For text
 285files this is the right thing to do: it corrects line endings
 286such that we have only LF line endings in the repository.
 287But for binary files that are accidentally classified as text the
 288conversion can corrupt data.
 289+
 290If you recognize such corruption early you can easily fix it by
 291setting the conversion type explicitly in .gitattributes.  Right
 292after committing you still have the original file in your work
 293tree and this file is not yet corrupted.  You can explicitly tell
 294Git that this file is binary and Git will handle the file
 295appropriately.
 296+
 297Unfortunately, the desired effect of cleaning up text files with
 298mixed line endings and the undesired effect of corrupting binary
 299files cannot be distinguished.  In both cases CRLFs are removed
 300in an irreversible way.  For text files this is the right thing
 301to do because CRLFs are line endings, while for binary files
 302converting CRLFs corrupts data.
 303+
 304Note, this safety check does not mean that a checkout will generate a
 305file identical to the original file for a different setting of
 306`core.eol` and `core.autocrlf`, but only for the current one.  For
 307example, a text file with `LF` would be accepted with `core.eol=lf`
 308and could later be checked out with `core.eol=crlf`, in which case the
 309resulting file would contain `CRLF`, although the original file
 310contained `LF`.  However, in both work trees the line endings would be
 311consistent, that is either all `LF` or all `CRLF`, but never mixed.  A
 312file with mixed line endings would be reported by the `core.safecrlf`
 313mechanism.
 314
 315core.autocrlf::
 316        Setting this variable to "true" is almost the same as setting
 317        the `text` attribute to "auto" on all files except that text
 318        files are not guaranteed to be normalized: files that contain
 319        `CRLF` in the repository will not be touched.  Use this
 320        setting if you want to have `CRLF` line endings in your
 321        working directory even though the repository does not have
 322        normalized line endings.  This variable can be set to 'input',
 323        in which case no output conversion is performed.
 324
 325core.symlinks::
 326        If false, symbolic links are checked out as small plain files that
 327        contain the link text. linkgit:git-update-index[1] and
 328        linkgit:git-add[1] will not change the recorded type to regular
 329        file. Useful on filesystems like FAT that do not support
 330        symbolic links.
 331+
 332The default is true, except linkgit:git-clone[1] or linkgit:git-init[1]
 333will probe and set core.symlinks false if appropriate when the repository
 334is created.
 335
 336core.gitProxy::
 337        A "proxy command" to execute (as 'command host port') instead
 338        of establishing direct connection to the remote server when
 339        using the Git protocol for fetching. If the variable value is
 340        in the "COMMAND for DOMAIN" format, the command is applied only
 341        on hostnames ending with the specified domain string. This variable
 342        may be set multiple times and is matched in the given order;
 343        the first match wins.
 344+
 345Can be overridden by the 'GIT_PROXY_COMMAND' environment variable
 346(which always applies universally, without the special "for"
 347handling).
 348+
 349The special string `none` can be used as the proxy command to
 350specify that no proxy be used for a given domain pattern.
 351This is useful for excluding servers inside a firewall from
 352proxy use, while defaulting to a common proxy for external domains.
 353
 354core.ignoreStat::
 355        If true, commands which modify both the working tree and the index
 356        will mark the updated paths with the "assume unchanged" bit in the
 357        index. These marked files are then assumed to stay unchanged in the
 358        working tree, until you mark them otherwise manually - Git will not
 359        detect the file changes by lstat() calls. This is useful on systems
 360        where those are very slow, such as Microsoft Windows.
 361        See linkgit:git-update-index[1].
 362        False by default.
 363
 364core.preferSymlinkRefs::
 365        Instead of the default "symref" format for HEAD
 366        and other symbolic reference files, use symbolic links.
 367        This is sometimes needed to work with old scripts that
 368        expect HEAD to be a symbolic link.
 369
 370core.bare::
 371        If true this repository is assumed to be 'bare' and has no
 372        working directory associated with it.  If this is the case a
 373        number of commands that require a working directory will be
 374        disabled, such as linkgit:git-add[1] or linkgit:git-merge[1].
 375+
 376This setting is automatically guessed by linkgit:git-clone[1] or
 377linkgit:git-init[1] when the repository was created.  By default a
 378repository that ends in "/.git" is assumed to be not bare (bare =
 379false), while all other repositories are assumed to be bare (bare
 380= true).
 381
 382core.worktree::
 383        Set the path to the root of the working tree.
 384        This can be overridden by the GIT_WORK_TREE environment
 385        variable and the '--work-tree' command line option.
 386        The value can be an absolute path or relative to the path to
 387        the .git directory, which is either specified by --git-dir
 388        or GIT_DIR, or automatically discovered.
 389        If --git-dir or GIT_DIR is specified but none of
 390        --work-tree, GIT_WORK_TREE and core.worktree is specified,
 391        the current working directory is regarded as the top level
 392        of your working tree.
 393+
 394Note that this variable is honored even when set in a configuration
 395file in a ".git" subdirectory of a directory and its value differs
 396from the latter directory (e.g. "/path/to/.git/config" has
 397core.worktree set to "/different/path"), which is most likely a
 398misconfiguration.  Running Git commands in the "/path/to" directory will
 399still use "/different/path" as the root of the work tree and can cause
 400confusion unless you know what you are doing (e.g. you are creating a
 401read-only snapshot of the same index to a location different from the
 402repository's usual working tree).
 403
 404core.logAllRefUpdates::
 405        Enable the reflog. Updates to a ref <ref> is logged to the file
 406        "$GIT_DIR/logs/<ref>", by appending the new and old
 407        SHA-1, the date/time and the reason of the update, but
 408        only when the file exists.  If this configuration
 409        variable is set to true, missing "$GIT_DIR/logs/<ref>"
 410        file is automatically created for branch heads (i.e. under
 411        refs/heads/), remote refs (i.e. under refs/remotes/),
 412        note refs (i.e. under refs/notes/), and the symbolic ref HEAD.
 413+
 414This information can be used to determine what commit
 415was the tip of a branch "2 days ago".
 416+
 417This value is true by default in a repository that has
 418a working directory associated with it, and false by
 419default in a bare repository.
 420
 421core.repositoryFormatVersion::
 422        Internal variable identifying the repository format and layout
 423        version.
 424
 425core.sharedRepository::
 426        When 'group' (or 'true'), the repository is made shareable between
 427        several users in a group (making sure all the files and objects are
 428        group-writable). When 'all' (or 'world' or 'everybody'), the
 429        repository will be readable by all users, additionally to being
 430        group-shareable. When 'umask' (or 'false'), Git will use permissions
 431        reported by umask(2). When '0xxx', where '0xxx' is an octal number,
 432        files in the repository will have this mode value. '0xxx' will override
 433        user's umask value (whereas the other options will only override
 434        requested parts of the user's umask value). Examples: '0660' will make
 435        the repo read/write-able for the owner and group, but inaccessible to
 436        others (equivalent to 'group' unless umask is e.g. '0022'). '0640' is a
 437        repository that is group-readable but not group-writable.
 438        See linkgit:git-init[1]. False by default.
 439
 440core.warnAmbiguousRefs::
 441        If true, Git will warn you if the ref name you passed it is ambiguous
 442        and might match multiple refs in the repository. True by default.
 443
 444core.compression::
 445        An integer -1..9, indicating a default compression level.
 446        -1 is the zlib default. 0 means no compression,
 447        and 1..9 are various speed/size tradeoffs, 9 being slowest.
 448        If set, this provides a default to other compression variables,
 449        such as 'core.loosecompression' and 'pack.compression'.
 450
 451core.loosecompression::
 452        An integer -1..9, indicating the compression level for objects that
 453        are not in a pack file. -1 is the zlib default. 0 means no
 454        compression, and 1..9 are various speed/size tradeoffs, 9 being
 455        slowest.  If not set,  defaults to core.compression.  If that is
 456        not set,  defaults to 1 (best speed).
 457
 458core.packedGitWindowSize::
 459        Number of bytes of a pack file to map into memory in a
 460        single mapping operation.  Larger window sizes may allow
 461        your system to process a smaller number of large pack files
 462        more quickly.  Smaller window sizes will negatively affect
 463        performance due to increased calls to the operating system's
 464        memory manager, but may improve performance when accessing
 465        a large number of large pack files.
 466+
 467Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
 468MiB on 32 bit platforms and 1 GiB on 64 bit platforms.  This should
 469be reasonable for all users/operating systems.  You probably do
 470not need to adjust this value.
 471+
 472Common unit suffixes of 'k', 'm', or 'g' are supported.
 473
 474core.packedGitLimit::
 475        Maximum number of bytes to map simultaneously into memory
 476        from pack files.  If Git needs to access more than this many
 477        bytes at once to complete an operation it will unmap existing
 478        regions to reclaim virtual address space within the process.
 479+
 480Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms.
 481This should be reasonable for all users/operating systems, except on
 482the largest projects.  You probably do not need to adjust this value.
 483+
 484Common unit suffixes of 'k', 'm', or 'g' are supported.
 485
 486core.deltaBaseCacheLimit::
 487        Maximum number of bytes to reserve for caching base objects
 488        that may be referenced by multiple deltified objects.  By storing the
 489        entire decompressed base objects in a cache Git is able
 490        to avoid unpacking and decompressing frequently used base
 491        objects multiple times.
 492+
 493Default is 16 MiB on all platforms.  This should be reasonable
 494for all users/operating systems, except on the largest projects.
 495You probably do not need to adjust this value.
 496+
 497Common unit suffixes of 'k', 'm', or 'g' are supported.
 498
 499core.bigFileThreshold::
 500        Files larger than this size are stored deflated, without
 501        attempting delta compression.  Storing large files without
 502        delta compression avoids excessive memory usage, at the
 503        slight expense of increased disk usage.
 504+
 505Default is 512 MiB on all platforms.  This should be reasonable
 506for most projects as source code and other text files can still
 507be delta compressed, but larger binary media files won't be.
 508+
 509Common unit suffixes of 'k', 'm', or 'g' are supported.
 510
 511core.excludesfile::
 512        In addition to '.gitignore' (per-directory) and
 513        '.git/info/exclude', Git looks into this file for patterns
 514        of files which are not meant to be tracked.  "`~/`" is expanded
 515        to the value of `$HOME` and "`~user/`" to the specified user's
 516        home directory. Its default value is $XDG_CONFIG_HOME/git/ignore.
 517        If $XDG_CONFIG_HOME is either not set or empty, $HOME/.config/git/ignore
 518        is used instead. See linkgit:gitignore[5].
 519
 520core.askpass::
 521        Some commands (e.g. svn and http interfaces) that interactively
 522        ask for a password can be told to use an external program given
 523        via the value of this variable. Can be overridden by the 'GIT_ASKPASS'
 524        environment variable. If not set, fall back to the value of the
 525        'SSH_ASKPASS' environment variable or, failing that, a simple password
 526        prompt. The external program shall be given a suitable prompt as
 527        command line argument and write the password on its STDOUT.
 528
 529core.attributesfile::
 530        In addition to '.gitattributes' (per-directory) and
 531        '.git/info/attributes', Git looks into this file for attributes
 532        (see linkgit:gitattributes[5]). Path expansions are made the same
 533        way as for `core.excludesfile`. Its default value is
 534        $XDG_CONFIG_HOME/git/attributes. If $XDG_CONFIG_HOME is either not
 535        set or empty, $HOME/.config/git/attributes is used instead.
 536
 537core.editor::
 538        Commands such as `commit` and `tag` that lets you edit
 539        messages by launching an editor uses the value of this
 540        variable when it is set, and the environment variable
 541        `GIT_EDITOR` is not set.  See linkgit:git-var[1].
 542
 543core.commentchar::
 544        Commands such as `commit` and `tag` that lets you edit
 545        messages consider a line that begins with this character
 546        commented, and removes them after the editor returns
 547        (default '#').
 548
 549sequence.editor::
 550        Text editor used by `git rebase -i` for editing the rebase instruction file.
 551        The value is meant to be interpreted by the shell when it is used.
 552        It can be overridden by the `GIT_SEQUENCE_EDITOR` environment variable.
 553        When not configured the default commit message editor is used instead.
 554
 555core.pager::
 556        Text viewer for use by Git commands (e.g., 'less').  The value
 557        is meant to be interpreted by the shell.  The order of preference
 558        is the `$GIT_PAGER` environment variable, then `core.pager`
 559        configuration, then `$PAGER`, and then the default chosen at
 560        compile time (usually 'less').
 561+
 562When the `LESS` environment variable is unset, Git sets it to `FRSX`
 563(if `LESS` environment variable is set, Git does not change it at
 564all).  If you want to selectively override Git's default setting
 565for `LESS`, you can set `core.pager` to e.g. `less -+S`.  This will
 566be passed to the shell by Git, which will translate the final
 567command to `LESS=FRSX less -+S`. The environment tells the command
 568to set the `S` option to chop long lines but the command line
 569resets it to the default to fold long lines.
 570
 571core.whitespace::
 572        A comma separated list of common whitespace problems to
 573        notice.  'git diff' will use `color.diff.whitespace` to
 574        highlight them, and 'git apply --whitespace=error' will
 575        consider them as errors.  You can prefix `-` to disable
 576        any of them (e.g. `-trailing-space`):
 577+
 578* `blank-at-eol` treats trailing whitespaces at the end of the line
 579  as an error (enabled by default).
 580* `space-before-tab` treats a space character that appears immediately
 581  before a tab character in the initial indent part of the line as an
 582  error (enabled by default).
 583* `indent-with-non-tab` treats a line that is indented with space
 584  characters instead of the equivalent tabs as an error (not enabled by
 585  default).
 586* `tab-in-indent` treats a tab character in the initial indent part of
 587  the line as an error (not enabled by default).
 588* `blank-at-eof` treats blank lines added at the end of file as an error
 589  (enabled by default).
 590* `trailing-space` is a short-hand to cover both `blank-at-eol` and
 591  `blank-at-eof`.
 592* `cr-at-eol` treats a carriage-return at the end of line as
 593  part of the line terminator, i.e. with it, `trailing-space`
 594  does not trigger if the character before such a carriage-return
 595  is not a whitespace (not enabled by default).
 596* `tabwidth=<n>` tells how many character positions a tab occupies; this
 597  is relevant for `indent-with-non-tab` and when Git fixes `tab-in-indent`
 598  errors. The default tab width is 8. Allowed values are 1 to 63.
 599
 600core.fsyncobjectfiles::
 601        This boolean will enable 'fsync()' when writing object files.
 602+
 603This is a total waste of time and effort on a filesystem that orders
 604data writes properly, but can be useful for filesystems that do not use
 605journalling (traditional UNIX filesystems) or that only journal metadata
 606and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback").
 607
 608core.preloadindex::
 609        Enable parallel index preload for operations like 'git diff'
 610+
 611This can speed up operations like 'git diff' and 'git status' especially
 612on filesystems like NFS that have weak caching semantics and thus
 613relatively high IO latencies.  With this set to 'true', Git will do the
 614index comparison to the filesystem data in parallel, allowing
 615overlapping IO's.
 616
 617core.createObject::
 618        You can set this to 'link', in which case a hardlink followed by
 619        a delete of the source are used to make sure that object creation
 620        will not overwrite existing objects.
 621+
 622On some file system/operating system combinations, this is unreliable.
 623Set this config setting to 'rename' there; However, This will remove the
 624check that makes sure that existing object files will not get overwritten.
 625
 626core.notesRef::
 627        When showing commit messages, also show notes which are stored in
 628        the given ref.  The ref must be fully qualified.  If the given
 629        ref does not exist, it is not an error but means that no
 630        notes should be printed.
 631+
 632This setting defaults to "refs/notes/commits", and it can be overridden by
 633the 'GIT_NOTES_REF' environment variable.  See linkgit:git-notes[1].
 634
 635core.sparseCheckout::
 636        Enable "sparse checkout" feature. See section "Sparse checkout" in
 637        linkgit:git-read-tree[1] for more information.
 638
 639core.abbrev::
 640        Set the length object names are abbreviated to.  If unspecified,
 641        many commands abbreviate to 7 hexdigits, which may not be enough
 642        for abbreviated object names to stay unique for sufficiently long
 643        time.
 644
 645add.ignore-errors::
 646add.ignoreErrors::
 647        Tells 'git add' to continue adding files when some files cannot be
 648        added due to indexing errors. Equivalent to the '--ignore-errors'
 649        option of linkgit:git-add[1].  Older versions of Git accept only
 650        `add.ignore-errors`, which does not follow the usual naming
 651        convention for configuration variables.  Newer versions of Git
 652        honor `add.ignoreErrors` as well.
 653
 654alias.*::
 655        Command aliases for the linkgit:git[1] command wrapper - e.g.
 656        after defining "alias.last = cat-file commit HEAD", the invocation
 657        "git last" is equivalent to "git cat-file commit HEAD". To avoid
 658        confusion and troubles with script usage, aliases that
 659        hide existing Git commands are ignored. Arguments are split by
 660        spaces, the usual shell quoting and escaping is supported.
 661        quote pair and a backslash can be used to quote them.
 662+
 663If the alias expansion is prefixed with an exclamation point,
 664it will be treated as a shell command.  For example, defining
 665"alias.new = !gitk --all --not ORIG_HEAD", the invocation
 666"git new" is equivalent to running the shell command
 667"gitk --all --not ORIG_HEAD".  Note that shell commands will be
 668executed from the top-level directory of a repository, which may
 669not necessarily be the current directory.
 670'GIT_PREFIX' is set as returned by running 'git rev-parse --show-prefix'
 671from the original current directory. See linkgit:git-rev-parse[1].
 672
 673am.keepcr::
 674        If true, git-am will call git-mailsplit for patches in mbox format
 675        with parameter '--keep-cr'. In this case git-mailsplit will
 676        not remove `\r` from lines ending with `\r\n`. Can be overridden
 677        by giving '--no-keep-cr' from the command line.
 678        See linkgit:git-am[1], linkgit:git-mailsplit[1].
 679
 680apply.ignorewhitespace::
 681        When set to 'change', tells 'git apply' to ignore changes in
 682        whitespace, in the same way as the '--ignore-space-change'
 683        option.
 684        When set to one of: no, none, never, false tells 'git apply' to
 685        respect all whitespace differences.
 686        See linkgit:git-apply[1].
 687
 688apply.whitespace::
 689        Tells 'git apply' how to handle whitespaces, in the same way
 690        as the '--whitespace' option. See linkgit:git-apply[1].
 691
 692branch.autosetupmerge::
 693        Tells 'git branch' and 'git checkout' to set up new branches
 694        so that linkgit:git-pull[1] will appropriately merge from the
 695        starting point branch. Note that even if this option is not set,
 696        this behavior can be chosen per-branch using the `--track`
 697        and `--no-track` options. The valid settings are: `false` -- no
 698        automatic setup is done; `true` -- automatic setup is done when the
 699        starting point is a remote-tracking branch; `always` --
 700        automatic setup is done when the starting point is either a
 701        local branch or remote-tracking
 702        branch. This option defaults to true.
 703
 704branch.autosetuprebase::
 705        When a new branch is created with 'git branch' or 'git checkout'
 706        that tracks another branch, this variable tells Git to set
 707        up pull to rebase instead of merge (see "branch.<name>.rebase").
 708        When `never`, rebase is never automatically set to true.
 709        When `local`, rebase is set to true for tracked branches of
 710        other local branches.
 711        When `remote`, rebase is set to true for tracked branches of
 712        remote-tracking branches.
 713        When `always`, rebase will be set to true for all tracking
 714        branches.
 715        See "branch.autosetupmerge" for details on how to set up a
 716        branch to track another branch.
 717        This option defaults to never.
 718
 719branch.<name>.remote::
 720        When on branch <name>, it tells 'git fetch' and 'git push'
 721        which remote to fetch from/push to.  The remote to push to
 722        may be overridden with `remote.pushdefault` (for all branches).
 723        The remote to push to, for the current branch, may be further
 724        overridden by `branch.<name>.pushremote`.  If no remote is
 725        configured, or if you are not on any branch, it defaults to
 726        `origin` for fetching and `remote.pushdefault` for pushing.
 727        Additionally, `.` (a period) is the current local repository
 728        (a dot-repository), see `branch.<name>.merge`'s final note below.
 729
 730branch.<name>.pushremote::
 731        When on branch <name>, it overrides `branch.<name>.remote` for
 732        pushing.  It also overrides `remote.pushdefault` for pushing
 733        from branch <name>.  When you pull from one place (e.g. your
 734        upstream) and push to another place (e.g. your own publishing
 735        repository), you would want to set `remote.pushdefault` to
 736        specify the remote to push to for all branches, and use this
 737        option to override it for a specific branch.
 738
 739branch.<name>.merge::
 740        Defines, together with branch.<name>.remote, the upstream branch
 741        for the given branch. It tells 'git fetch'/'git pull'/'git rebase' which
 742        branch to merge and can also affect 'git push' (see push.default).
 743        When in branch <name>, it tells 'git fetch' the default
 744        refspec to be marked for merging in FETCH_HEAD. The value is
 745        handled like the remote part of a refspec, and must match a
 746        ref which is fetched from the remote given by
 747        "branch.<name>.remote".
 748        The merge information is used by 'git pull' (which at first calls
 749        'git fetch') to lookup the default branch for merging. Without
 750        this option, 'git pull' defaults to merge the first refspec fetched.
 751        Specify multiple values to get an octopus merge.
 752        If you wish to setup 'git pull' so that it merges into <name> from
 753        another branch in the local repository, you can point
 754        branch.<name>.merge to the desired branch, and use the relative path
 755        setting `.` (a period) for branch.<name>.remote.
 756
 757branch.<name>.mergeoptions::
 758        Sets default options for merging into branch <name>. The syntax and
 759        supported options are the same as those of linkgit:git-merge[1], but
 760        option values containing whitespace characters are currently not
 761        supported.
 762
 763branch.<name>.rebase::
 764        When true, rebase the branch <name> on top of the fetched branch,
 765        instead of merging the default branch from the default remote when
 766        "git pull" is run. See "pull.rebase" for doing this in a non
 767        branch-specific manner.
 768+
 769        When preserve, also pass `--preserve-merges` along to 'git rebase'
 770        so that locally committed merge commits will not be flattened
 771        by running 'git pull'.
 772+
 773*NOTE*: this is a possibly dangerous operation; do *not* use
 774it unless you understand the implications (see linkgit:git-rebase[1]
 775for details).
 776
 777branch.<name>.description::
 778        Branch description, can be edited with
 779        `git branch --edit-description`. Branch description is
 780        automatically added in the format-patch cover letter or
 781        request-pull summary.
 782
 783browser.<tool>.cmd::
 784        Specify the command to invoke the specified browser. The
 785        specified command is evaluated in shell with the URLs passed
 786        as arguments. (See linkgit:git-web{litdd}browse[1].)
 787
 788browser.<tool>.path::
 789        Override the path for the given tool that may be used to
 790        browse HTML help (see '-w' option in linkgit:git-help[1]) or a
 791        working repository in gitweb (see linkgit:git-instaweb[1]).
 792
 793clean.requireForce::
 794        A boolean to make git-clean do nothing unless given -f,
 795        -i or -n.   Defaults to true.
 796
 797color.branch::
 798        A boolean to enable/disable color in the output of
 799        linkgit:git-branch[1]. May be set to `always`,
 800        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 801        only when the output is to a terminal. Defaults to false.
 802
 803color.branch.<slot>::
 804        Use customized color for branch coloration. `<slot>` is one of
 805        `current` (the current branch), `local` (a local branch),
 806        `remote` (a remote-tracking branch in refs/remotes/),
 807        `upstream` (upstream tracking branch), `plain` (other
 808        refs).
 809+
 810The value for these configuration variables is a list of colors (at most
 811two) and attributes (at most one), separated by spaces.  The colors
 812accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`,
 813`magenta`, `cyan` and `white`; the attributes are `bold`, `dim`, `ul`,
 814`blink` and `reverse`.  The first color given is the foreground; the
 815second is the background.  The position of the attribute, if any,
 816doesn't matter.
 817
 818color.diff::
 819        Whether to use ANSI escape sequences to add color to patches.
 820        If this is set to `always`, linkgit:git-diff[1],
 821        linkgit:git-log[1], and linkgit:git-show[1] will use color
 822        for all patches.  If it is set to `true` or `auto`, those
 823        commands will only use color when output is to the terminal.
 824        Defaults to false.
 825+
 826This does not affect linkgit:git-format-patch[1] nor the
 827'git-diff-{asterisk}' plumbing commands.  Can be overridden on the
 828command line with the `--color[=<when>]` option.
 829
 830color.diff.<slot>::
 831        Use customized color for diff colorization.  `<slot>` specifies
 832        which part of the patch to use the specified color, and is one
 833        of `plain` (context text), `meta` (metainformation), `frag`
 834        (hunk header), 'func' (function in hunk header), `old` (removed lines),
 835        `new` (added lines), `commit` (commit headers), or `whitespace`
 836        (highlighting whitespace errors). The values of these variables may be
 837        specified as in color.branch.<slot>.
 838
 839color.decorate.<slot>::
 840        Use customized color for 'git log --decorate' output.  `<slot>` is one
 841        of `branch`, `remoteBranch`, `tag`, `stash` or `HEAD` for local
 842        branches, remote-tracking branches, tags, stash and HEAD, respectively.
 843
 844color.grep::
 845        When set to `always`, always highlight matches.  When `false` (or
 846        `never`), never.  When set to `true` or `auto`, use color only
 847        when the output is written to the terminal.  Defaults to `false`.
 848
 849color.grep.<slot>::
 850        Use customized color for grep colorization.  `<slot>` specifies which
 851        part of the line to use the specified color, and is one of
 852+
 853--
 854`context`;;
 855        non-matching text in context lines (when using `-A`, `-B`, or `-C`)
 856`filename`;;
 857        filename prefix (when not using `-h`)
 858`function`;;
 859        function name lines (when using `-p`)
 860`linenumber`;;
 861        line number prefix (when using `-n`)
 862`match`;;
 863        matching text
 864`selected`;;
 865        non-matching text in selected lines
 866`separator`;;
 867        separators between fields on a line (`:`, `-`, and `=`)
 868        and between hunks (`--`)
 869--
 870+
 871The values of these variables may be specified as in color.branch.<slot>.
 872
 873color.interactive::
 874        When set to `always`, always use colors for interactive prompts
 875        and displays (such as those used by "git-add --interactive" and
 876        "git-clean --interactive"). When false (or `never`), never.
 877        When set to `true` or `auto`, use colors only when the output is
 878        to the terminal. Defaults to false.
 879
 880color.interactive.<slot>::
 881        Use customized color for 'git add --interactive' and 'git clean
 882        --interactive' output. `<slot>` may be `prompt`, `header`, `help`
 883        or `error`, for four distinct types of normal output from
 884        interactive commands.  The values of these variables may be
 885        specified as in color.branch.<slot>.
 886
 887color.pager::
 888        A boolean to enable/disable colored output when the pager is in
 889        use (default is true).
 890
 891color.showbranch::
 892        A boolean to enable/disable color in the output of
 893        linkgit:git-show-branch[1]. May be set to `always`,
 894        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 895        only when the output is to a terminal. Defaults to false.
 896
 897color.status::
 898        A boolean to enable/disable color in the output of
 899        linkgit:git-status[1]. May be set to `always`,
 900        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 901        only when the output is to a terminal. Defaults to false.
 902
 903color.status.<slot>::
 904        Use customized color for status colorization. `<slot>` is
 905        one of `header` (the header text of the status message),
 906        `added` or `updated` (files which are added but not committed),
 907        `changed` (files which are changed but not added in the index),
 908        `untracked` (files which are not tracked by Git),
 909        `branch` (the current branch), or
 910        `nobranch` (the color the 'no branch' warning is shown in, defaulting
 911        to red). The values of these variables may be specified as in
 912        color.branch.<slot>.
 913
 914color.ui::
 915        This variable determines the default value for variables such
 916        as `color.diff` and `color.grep` that control the use of color
 917        per command family. Its scope will expand as more commands learn
 918        configuration to set a default for the `--color` option.  Set it
 919        to `false` or `never` if you prefer Git commands not to use
 920        color unless enabled explicitly with some other configuration
 921        or the `--color` option. Set it to `always` if you want all
 922        output not intended for machine consumption to use color, to
 923        `true` or `auto` (this is the default since Git 1.8.4) if you
 924        want such output to use color when written to the terminal.
 925
 926column.ui::
 927        Specify whether supported commands should output in columns.
 928        This variable consists of a list of tokens separated by spaces
 929        or commas:
 930+
 931These options control when the feature should be enabled
 932(defaults to 'never'):
 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--
 942+
 943These options control layout (defaults to 'column').  Setting any
 944of these implies 'always' if none of 'always', 'never', or 'auto' are
 945specified.
 946+
 947--
 948`column`;;
 949        fill columns before rows
 950`row`;;
 951        fill rows before columns
 952`plain`;;
 953        show in one column
 954--
 955+
 956Finally, these options can be combined with a layout option (defaults
 957to 'nodense'):
 958+
 959--
 960`dense`;;
 961        make unequal size columns to utilize more space
 962`nodense`;;
 963        make equal size columns
 964--
 965
 966column.branch::
 967        Specify whether to output branch listing in `git branch` in columns.
 968        See `column.ui` for details.
 969
 970column.clean::
 971        Specify the layout when list items in `git clean -i`, which always
 972        shows files and directories in columns. See `column.ui` for details.
 973
 974column.status::
 975        Specify whether to output untracked files in `git status` in columns.
 976        See `column.ui` for details.
 977
 978column.tag::
 979        Specify whether to output tag listing in `git tag` in columns.
 980        See `column.ui` for details.
 981
 982commit.cleanup::
 983        This setting overrides the default of the `--cleanup` option in
 984        `git commit`. See linkgit:git-commit[1] for details. Changing the
 985        default can be useful when you always want to keep lines that begin
 986        with comment character `#` in your log message, in which case you
 987        would do `git config commit.cleanup whitespace` (note that you will
 988        have to remove the help lines that begin with `#` in the commit log
 989        template yourself, if you do this).
 990
 991commit.status::
 992        A boolean to enable/disable inclusion of status information in the
 993        commit message template when using an editor to prepare the commit
 994        message.  Defaults to true.
 995
 996commit.template::
 997        Specify a file to use as the template for new commit messages.
 998        "`~/`" is expanded to the value of `$HOME` and "`~user/`" to the
 999        specified user's home directory.
1000
1001credential.helper::
1002        Specify an external helper to be called when a username or
1003        password credential is needed; the helper may consult external
1004        storage to avoid prompting the user for the credentials. See
1005        linkgit:gitcredentials[7] for details.
1006
1007credential.useHttpPath::
1008        When acquiring credentials, consider the "path" component of an http
1009        or https URL to be important. Defaults to false. See
1010        linkgit:gitcredentials[7] for more information.
1011
1012credential.username::
1013        If no username is set for a network authentication, use this username
1014        by default. See credential.<context>.* below, and
1015        linkgit:gitcredentials[7].
1016
1017credential.<url>.*::
1018        Any of the credential.* options above can be applied selectively to
1019        some credentials. For example "credential.https://example.com.username"
1020        would set the default username only for https connections to
1021        example.com. See linkgit:gitcredentials[7] for details on how URLs are
1022        matched.
1023
1024include::diff-config.txt[]
1025
1026difftool.<tool>.path::
1027        Override the path for the given tool.  This is useful in case
1028        your tool is not in the PATH.
1029
1030difftool.<tool>.cmd::
1031        Specify the command to invoke the specified diff tool.
1032        The specified command is evaluated in shell with the following
1033        variables available:  'LOCAL' is set to the name of the temporary
1034        file containing the contents of the diff pre-image and 'REMOTE'
1035        is set to the name of the temporary file containing the contents
1036        of the diff post-image.
1037
1038difftool.prompt::
1039        Prompt before each invocation of the diff tool.
1040
1041fetch.recurseSubmodules::
1042        This option can be either set to a boolean value or to 'on-demand'.
1043        Setting it to a boolean changes the behavior of fetch and pull to
1044        unconditionally recurse into submodules when set to true or to not
1045        recurse at all when set to false. When set to 'on-demand' (the default
1046        value), fetch and pull will only recurse into a populated submodule
1047        when its superproject retrieves a commit that updates the submodule's
1048        reference.
1049
1050fetch.fsckObjects::
1051        If it is set to true, git-fetch-pack will check all fetched
1052        objects. It will abort in the case of a malformed object or a
1053        broken link. The result of an abort are only dangling objects.
1054        Defaults to false. If not set, the value of `transfer.fsckObjects`
1055        is used instead.
1056
1057fetch.unpackLimit::
1058        If the number of objects fetched over the Git native
1059        transfer is below this
1060        limit, then the objects will be unpacked into loose object
1061        files. However if the number of received objects equals or
1062        exceeds this limit then the received pack will be stored as
1063        a pack, after adding any missing delta bases.  Storing the
1064        pack from a push can make the push operation complete faster,
1065        especially on slow filesystems.  If not set, the value of
1066        `transfer.unpackLimit` is used instead.
1067
1068fetch.prune::
1069        If true, fetch will automatically behave as if the `--prune`
1070        option was given on the command line.  See also `remote.<name>.prune`.
1071
1072format.attach::
1073        Enable multipart/mixed attachments as the default for
1074        'format-patch'.  The value can also be a double quoted string
1075        which will enable attachments as the default and set the
1076        value as the boundary.  See the --attach option in
1077        linkgit:git-format-patch[1].
1078
1079format.numbered::
1080        A boolean which can enable or disable sequence numbers in patch
1081        subjects.  It defaults to "auto" which enables it only if there
1082        is more than one patch.  It can be enabled or disabled for all
1083        messages by setting it to "true" or "false".  See --numbered
1084        option in linkgit:git-format-patch[1].
1085
1086format.headers::
1087        Additional email headers to include in a patch to be submitted
1088        by mail.  See linkgit:git-format-patch[1].
1089
1090format.to::
1091format.cc::
1092        Additional recipients to include in a patch to be submitted
1093        by mail.  See the --to and --cc options in
1094        linkgit:git-format-patch[1].
1095
1096format.subjectprefix::
1097        The default for format-patch is to output files with the '[PATCH]'
1098        subject prefix. Use this variable to change that prefix.
1099
1100format.signature::
1101        The default for format-patch is to output a signature containing
1102        the Git version number. Use this variable to change that default.
1103        Set this variable to the empty string ("") to suppress
1104        signature generation.
1105
1106format.suffix::
1107        The default for format-patch is to output files with the suffix
1108        `.patch`. Use this variable to change that suffix (make sure to
1109        include the dot if you want it).
1110
1111format.pretty::
1112        The default pretty format for log/show/whatchanged command,
1113        See linkgit:git-log[1], linkgit:git-show[1],
1114        linkgit:git-whatchanged[1].
1115
1116format.thread::
1117        The default threading style for 'git format-patch'.  Can be
1118        a boolean value, or `shallow` or `deep`.  `shallow` threading
1119        makes every mail a reply to the head of the series,
1120        where the head is chosen from the cover letter, the
1121        `--in-reply-to`, and the first patch mail, in this order.
1122        `deep` threading makes every mail a reply to the previous one.
1123        A true boolean value is the same as `shallow`, and a false
1124        value disables threading.
1125
1126format.signoff::
1127        A boolean value which lets you enable the `-s/--signoff` option of
1128        format-patch by default. *Note:* Adding the Signed-off-by: line to a
1129        patch should be a conscious act and means that you certify you have
1130        the rights to submit this work under the same open source license.
1131        Please see the 'SubmittingPatches' document for further discussion.
1132
1133format.coverLetter::
1134        A boolean that controls whether to generate a cover-letter when
1135        format-patch is invoked, but in addition can be set to "auto", to
1136        generate a cover-letter only when there's more than one patch.
1137
1138filter.<driver>.clean::
1139        The command which is used to convert the content of a worktree
1140        file to a blob upon checkin.  See linkgit:gitattributes[5] for
1141        details.
1142
1143filter.<driver>.smudge::
1144        The command which is used to convert the content of a blob
1145        object to a worktree file upon checkout.  See
1146        linkgit:gitattributes[5] for details.
1147
1148gc.aggressiveWindow::
1149        The window size parameter used in the delta compression
1150        algorithm used by 'git gc --aggressive'.  This defaults
1151        to 250.
1152
1153gc.auto::
1154        When there are approximately more than this many loose
1155        objects in the repository, `git gc --auto` will pack them.
1156        Some Porcelain commands use this command to perform a
1157        light-weight garbage collection from time to time.  The
1158        default value is 6700.  Setting this to 0 disables it.
1159
1160gc.autopacklimit::
1161        When there are more than this many packs that are not
1162        marked with `*.keep` file in the repository, `git gc
1163        --auto` consolidates them into one larger pack.  The
1164        default value is 50.  Setting this to 0 disables it.
1165
1166gc.packrefs::
1167        Running `git pack-refs` in a repository renders it
1168        unclonable by Git versions prior to 1.5.1.2 over dumb
1169        transports such as HTTP.  This variable determines whether
1170        'git gc' runs `git pack-refs`. This can be set to `notbare`
1171        to enable it within all non-bare repos or it can be set to a
1172        boolean value.  The default is `true`.
1173
1174gc.pruneexpire::
1175        When 'git gc' is run, it will call 'prune --expire 2.weeks.ago'.
1176        Override the grace period with this config variable.  The value
1177        "now" may be used to disable this  grace period and always prune
1178        unreachable objects immediately.
1179
1180gc.reflogexpire::
1181gc.<pattern>.reflogexpire::
1182        'git reflog expire' removes reflog entries older than
1183        this time; defaults to 90 days.  With "<pattern>" (e.g.
1184        "refs/stash") in the middle the setting applies only to
1185        the refs that match the <pattern>.
1186
1187gc.reflogexpireunreachable::
1188gc.<ref>.reflogexpireunreachable::
1189        'git reflog expire' removes reflog entries older than
1190        this time and are not reachable from the current tip;
1191        defaults to 30 days.  With "<pattern>" (e.g. "refs/stash")
1192        in the middle, the setting applies only to the refs that
1193        match the <pattern>.
1194
1195gc.rerereresolved::
1196        Records of conflicted merge you resolved earlier are
1197        kept for this many days when 'git rerere gc' is run.
1198        The default is 60 days.  See linkgit:git-rerere[1].
1199
1200gc.rerereunresolved::
1201        Records of conflicted merge you have not resolved are
1202        kept for this many days when 'git rerere gc' is run.
1203        The default is 15 days.  See linkgit:git-rerere[1].
1204
1205gitcvs.commitmsgannotation::
1206        Append this string to each commit message. Set to empty string
1207        to disable this feature. Defaults to "via git-CVS emulator".
1208
1209gitcvs.enabled::
1210        Whether the CVS server interface is enabled for this repository.
1211        See linkgit:git-cvsserver[1].
1212
1213gitcvs.logfile::
1214        Path to a log file where the CVS server interface well... logs
1215        various stuff. See linkgit:git-cvsserver[1].
1216
1217gitcvs.usecrlfattr::
1218        If true, the server will look up the end-of-line conversion
1219        attributes for files to determine the '-k' modes to use. If
1220        the attributes force Git to treat a file as text,
1221        the '-k' mode will be left blank so CVS clients will
1222        treat it as text. If they suppress text conversion, the file
1223        will be set with '-kb' mode, which suppresses any newline munging
1224        the client might otherwise do. If the attributes do not allow
1225        the file type to be determined, then 'gitcvs.allbinary' is
1226        used. See linkgit:gitattributes[5].
1227
1228gitcvs.allbinary::
1229        This is used if 'gitcvs.usecrlfattr' does not resolve
1230        the correct '-kb' mode to use. If true, all
1231        unresolved files are sent to the client in
1232        mode '-kb'. This causes the client to treat them
1233        as binary files, which suppresses any newline munging it
1234        otherwise might do. Alternatively, if it is set to "guess",
1235        then the contents of the file are examined to decide if
1236        it is binary, similar to 'core.autocrlf'.
1237
1238gitcvs.dbname::
1239        Database used by git-cvsserver to cache revision information
1240        derived from the Git repository. The exact meaning depends on the
1241        used database driver, for SQLite (which is the default driver) this
1242        is a filename. Supports variable substitution (see
1243        linkgit:git-cvsserver[1] for details). May not contain semicolons (`;`).
1244        Default: '%Ggitcvs.%m.sqlite'
1245
1246gitcvs.dbdriver::
1247        Used Perl DBI driver. You can specify any available driver
1248        for this here, but it might not work. git-cvsserver is tested
1249        with 'DBD::SQLite', reported to work with 'DBD::Pg', and
1250        reported *not* to work with 'DBD::mysql'. Experimental feature.
1251        May not contain double colons (`:`). Default: 'SQLite'.
1252        See linkgit:git-cvsserver[1].
1253
1254gitcvs.dbuser, gitcvs.dbpass::
1255        Database user and password. Only useful if setting 'gitcvs.dbdriver',
1256        since SQLite has no concept of database users and/or passwords.
1257        'gitcvs.dbuser' supports variable substitution (see
1258        linkgit:git-cvsserver[1] for details).
1259
1260gitcvs.dbTableNamePrefix::
1261        Database table name prefix.  Prepended to the names of any
1262        database tables used, allowing a single database to be used
1263        for several repositories.  Supports variable substitution (see
1264        linkgit:git-cvsserver[1] for details).  Any non-alphabetic
1265        characters will be replaced with underscores.
1266
1267All gitcvs variables except for 'gitcvs.usecrlfattr' and
1268'gitcvs.allbinary' can also be specified as
1269'gitcvs.<access_method>.<varname>' (where 'access_method'
1270is one of "ext" and "pserver") to make them apply only for the given
1271access method.

1289
1290grep.lineNumber::
1291        If set to true, enable '-n' option by default.
1292
1293grep.patternType::
1294        Set the default matching behavior. Using a value of 'basic', 'extended',
1295        'fixed', or 'perl' will enable the '--basic-regexp', '--extended-regexp',
1296        '--fixed-strings', or '--perl-regexp' option accordingly, while the
1297        value 'default' will return to the default matching behavior.
1298
1299grep.extendedRegexp::
1300        If set to true, enable '--extended-regexp' option by default. This
1301        option is ignored when the 'grep.patternType' option is set to a value
1302        other than 'default'.
1303
1304gpg.program::
1305        Use this custom program instead of "gpg" found on $PATH when
1306        making or verifying a PGP signature. The program must support the
1307        same command line interface as GPG, namely, to verify a detached
1308        signature, "gpg --verify $file - <$signature" is run, and the
1309        program is expected to signal a good signature by exiting with
1310        code 0, and to generate an ascii-armored detached signature, the
1311        standard input of "gpg -bsau $key" is fed with the contents to be
1312        signed, and the program is expected to send the result to its
1313        standard output.
1314
1315gui.commitmsgwidth::
1316        Defines how wide the commit message window is in the
1317        linkgit:git-gui[1]. "75" is the default.
1318
1319gui.diffcontext::
1320        Specifies how many context lines should be used in calls to diff
1321        made by the linkgit:git-gui[1]. The default is "5".
1322
1323gui.encoding::
1324        Specifies the default encoding to use for displaying of
1325        file contents in linkgit:git-gui[1] and linkgit:gitk[1].
1326        It can be overridden by setting the 'encoding' attribute
1327        for relevant files (see linkgit:gitattributes[5]).
1328        If this option is not set, the tools default to the
1329        locale encoding.
1330
1331gui.matchtrackingbranch::
1332        Determines if new branches created with linkgit:git-gui[1] should
1333        default to tracking remote branches with matching names or
1334        not. Default: "false".
1335
1336gui.newbranchtemplate::
1337        Is used as suggested name when creating new branches using the
1338        linkgit:git-gui[1].
1339
1340gui.pruneduringfetch::
1341        "true" if linkgit:git-gui[1] should prune remote-tracking branches when
1342        performing a fetch. The default value is "false".
1343
1344gui.trustmtime::
1345        Determines if linkgit:git-gui[1] should trust the file modification
1346        timestamp or not. By default the timestamps are not trusted.
1347
1348gui.spellingdictionary::
1349        Specifies the dictionary used for spell checking commit messages in
1350        the linkgit:git-gui[1]. When set to "none" spell checking is turned
1351        off.
1352
1353gui.fastcopyblame::
1354        If true, 'git gui blame' uses `-C` instead of `-C -C` for original
1355        location detection. It makes blame significantly faster on huge
1356        repositories at the expense of less thorough copy detection.
1357
1358gui.copyblamethreshold::
1359        Specifies the threshold to use in 'git gui blame' original location
1360        detection, measured in alphanumeric characters. See the
1361        linkgit:git-blame[1] manual for more information on copy detection.
1362
1363gui.blamehistoryctx::
1364        Specifies the radius of history context in days to show in
1365        linkgit:gitk[1] for the selected commit, when the `Show History
1366        Context` menu item is invoked from 'git gui blame'. If this
1367        variable is set to zero, the whole history is shown.
1368
1369guitool.<name>.cmd::
1370        Specifies the shell command line to execute when the corresponding item
1371        of the linkgit:git-gui[1] `Tools` menu is invoked. This option is
1372        mandatory for every tool. The command is executed from the root of
1373        the working directory, and in the environment it receives the name of
1374        the tool as 'GIT_GUITOOL', the name of the currently selected file as
1375        'FILENAME', and the name of the current branch as 'CUR_BRANCH' (if
1376        the head is detached, 'CUR_BRANCH' is empty).
1377
1378guitool.<name>.needsfile::
1379        Run the tool only if a diff is selected in the GUI. It guarantees
1380        that 'FILENAME' is not empty.
1381
1382guitool.<name>.noconsole::
1383        Run the command silently, without creating a window to display its
1384        output.
1385
1386guitool.<name>.norescan::
1387        Don't rescan the working directory for changes after the tool
1388        finishes execution.
1389
1390guitool.<name>.confirm::
1391        Show a confirmation dialog before actually running the tool.
1392
1393guitool.<name>.argprompt::
1394        Request a string argument from the user, and pass it to the tool
1395        through the 'ARGS' environment variable. Since requesting an
1396        argument implies confirmation, the 'confirm' option has no effect
1397        if this is enabled. If the option is set to 'true', 'yes', or '1',
1398        the dialog uses a built-in generic prompt; otherwise the exact
1399        value of the variable is used.
1400
1401guitool.<name>.revprompt::
1402        Request a single valid revision from the user, and set the
1403        'REVISION' environment variable. In other aspects this option
1404        is similar to 'argprompt', and can be used together with it.
1405
1406guitool.<name>.revunmerged::
1407        Show only unmerged branches in the 'revprompt' subdialog.
1408        This is useful for tools similar to merge or rebase, but not
1409        for things like checkout or reset.
1410
1411guitool.<name>.title::
1412        Specifies the title to use for the prompt dialog. The default
1413        is the tool name.
1414
1415guitool.<name>.prompt::
1416        Specifies the general prompt string to display at the top of
1417        the dialog, before subsections for 'argprompt' and 'revprompt'.
1418        The default value includes the actual command.
1419
1420help.browser::
1421        Specify the browser that will be used to display help in the
1422        'web' format. See linkgit:git-help[1].
1423
1424help.format::
1425        Override the default help format used by linkgit:git-help[1].
1426        Values 'man', 'info', 'web' and 'html' are supported. 'man' is
1427        the default. 'web' and 'html' are the same.
1428
1429help.autocorrect::
1430        Automatically correct and execute mistyped commands after
1431        waiting for the given number of deciseconds (0.1 sec). If more
1432        than one command can be deduced from the entered text, nothing
1433        will be executed.  If the value of this option is negative,
1434        the corrected command will be executed immediately. If the
1435        value is 0 - the command will be just shown but not executed.
1436        This is the default.
1437
1438help.htmlpath::
1439        Specify the path where the HTML documentation resides. File system paths
1440        and URLs are supported. HTML pages will be prefixed with this path when
1441        help is displayed in the 'web' format. This defaults to the documentation
1442        path of your Git installation.
1443
1444http.proxy::
1445        Override the HTTP proxy, normally configured using the 'http_proxy',
1446        'https_proxy', and 'all_proxy' environment variables (see
1447        `curl(1)`).  This can be overridden on a per-remote basis; see
1448        remote.<name>.proxy
1449
1450http.cookiefile::
1451        File containing previously stored cookie lines which should be used
1452        in the Git http session, if they match the server. The file format
1453        of the file to read cookies from should be plain HTTP headers or
1454        the Netscape/Mozilla cookie file format (see linkgit:curl[1]).
1455        NOTE that the file specified with http.cookiefile is only used as
1456        input unless http.saveCookies is set.
1457
1458http.savecookies::
1459        If set, store cookies received during requests to the file specified by
1460        http.cookiefile. Has no effect if http.cookiefile is unset.
1461
1462http.sslVerify::
1463        Whether to verify the SSL certificate when fetching or pushing
1464        over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
1465        variable.
1466
1467http.sslCert::
1468        File containing the SSL certificate when fetching or pushing
1469        over HTTPS. Can be overridden by the 'GIT_SSL_CERT' environment
1470        variable.
1471
1472http.sslKey::
1473        File containing the SSL private key when fetching or pushing
1474        over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment
1475        variable.
1476
1477http.sslCertPasswordProtected::
1478        Enable Git's password prompt for the SSL certificate.  Otherwise
1479        OpenSSL will prompt the user, possibly many times, if the
1480        certificate or private key is encrypted.  Can be overridden by the
1481        'GIT_SSL_CERT_PASSWORD_PROTECTED' environment variable.
1482
1483http.sslCAInfo::
1484        File containing the certificates to verify the peer with when
1485        fetching or pushing over HTTPS. Can be overridden by the
1486        'GIT_SSL_CAINFO' environment variable.
1487
1488http.sslCAPath::
1489        Path containing files with the CA certificates to verify the peer
1490        with when fetching or pushing over HTTPS. Can be overridden
1491        by the 'GIT_SSL_CAPATH' environment variable.
1492
1493http.sslTry::
1494        Attempt to use AUTH SSL/TLS and encrypted data transfers
1495        when connecting via regular FTP protocol. This might be needed
1496        if the FTP server requires it for security reasons or you wish
1497        to connect securely whenever remote FTP server supports it.
1498        Default is false since it might trigger certificate verification
1499        errors on misconfigured servers.
1500
1501http.maxRequests::
1502        How many HTTP requests to launch in parallel. Can be overridden
1503        by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5.
1504
1505http.minSessions::
1506        The number of curl sessions (counted across slots) to be kept across
1507        requests. They will not be ended with curl_easy_cleanup() until
1508        http_cleanup() is invoked. If USE_CURL_MULTI is not defined, this
1509        value will be capped at 1. Defaults to 1.
1510
1511http.postBuffer::
1512        Maximum size in bytes of the buffer used by smart HTTP
1513        transports when POSTing data to the remote system.
1514        For requests larger than this buffer size, HTTP/1.1 and
1515        Transfer-Encoding: chunked is used to avoid creating a
1516        massive pack file locally.  Default is 1 MiB, which is
1517        sufficient for most requests.
1518
1519http.lowSpeedLimit, http.lowSpeedTime::
1520        If the HTTP transfer speed is less than 'http.lowSpeedLimit'
1521        for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
1522        Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and
1523        'GIT_HTTP_LOW_SPEED_TIME' environment variables.
1524
1525http.noEPSV::
1526        A boolean which disables using of EPSV ftp command by curl.
1527        This can helpful with some "poor" ftp servers which don't
1528        support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
1529        environment variable. Default is false (curl will use EPSV).
1530
1531http.useragent::
1532        The HTTP USER_AGENT string presented to an HTTP server.  The default
1533        value represents the version of the client Git such as git/1.7.1.
1534        This option allows you to override this value to a more common value
1535        such as Mozilla/4.0.  This may be necessary, for instance, if
1536        connecting through a firewall that restricts HTTP connections to a set
1537        of common USER_AGENT strings (but not including those like git/1.7.1).
1538        Can be overridden by the 'GIT_HTTP_USER_AGENT' environment variable.
1539
1540http.<url>.*::
1541        Any of the http.* options above can be applied selectively to some urls.
1542        For a config key to match a URL, each element of the config key is
1543        compared to that of the URL, in the following order:
1544+
1545--
1546. Scheme (e.g., `https` in `https://example.com/`). This field
1547  must match exactly between the config key and the URL.
1548
1549. Host/domain name (e.g., `example.com` in `https://example.com/`).
1550  This field must match exactly between the config key and the URL.
1551
1552. Port number (e.g., `8080` in `http://example.com:8080/`).
1553  This field must match exactly between the config key and the URL.
1554  Omitted port numbers are automatically converted to the correct
1555  default for the scheme before matching.
1556
1557. Path (e.g., `repo.git` in `https://example.com/repo.git`). The
1558  path field of the config key must match the path field of the URL
1559  either exactly or as a prefix of slash-delimited path elements.  This means
1560  a config key with path `foo/` matches URL path `foo/bar`.  A prefix can only
1561  match on a slash (`/`) boundary.  Longer matches take precedence (so a config
1562  key with path `foo/bar` is a better match to URL path `foo/bar` than a config
1563  key with just path `foo/`).
1564
1565. User name (e.g., `user` in `https://user@example.com/repo.git`). If
1566  the config key has a user name it must match the user name in the
1567  URL exactly. If the config key does not have a user name, that
1568  config key will match a URL with any user name (including none),
1569  but at a lower precedence than a config key with a user name.
1570--
1571+
1572The list above is ordered by decreasing precedence; a URL that matches
1573a config key's path is preferred to one that matches its user name. For example,
1574if the URL is `https://user@example.com/foo/bar` a config key match of
1575`https://example.com/foo` will be preferred over a config key match of
1576`https://user@example.com`.
1577+
1578All URLs are normalized before attempting any matching (the password part,
1579if embedded in the URL, is always ignored for matching purposes) so that
1580equivalent urls that are simply spelled differently will match properly.
1581Environment variable settings always override any matches.  The urls that are
1582matched against are those given directly to Git commands.  This means any URLs
1583visited as a result of a redirection do not participate in matching.
1584
1585i18n.commitEncoding::
1586        Character encoding the commit messages are stored in; Git itself
1587        does not care per se, but this information is necessary e.g. when
1588        importing commits from emails or in the gitk graphical history
1589        browser (and possibly at other places in the future or in other
1590        porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.
1591
1592i18n.logOutputEncoding::
1593        Character encoding the commit messages are converted to when
1594        running 'git log' and friends.
1595
1596imap::
1597        The configuration variables in the 'imap' section are described
1598        in linkgit:git-imap-send[1].
1599
1600init.templatedir::
1601        Specify the directory from which templates will be copied.
1602        (See the "TEMPLATE DIRECTORY" section of linkgit:git-init[1].)
1603
1604instaweb.browser::
1605        Specify the program that will be used to browse your working
1606        repository in gitweb. See linkgit:git-instaweb[1].
1607
1608instaweb.httpd::
1609        The HTTP daemon command-line to start gitweb on your working
1610        repository. See linkgit:git-instaweb[1].
1611
1612instaweb.local::
1613        If true the web server started by linkgit:git-instaweb[1] will
1614        be bound to the local IP (127.0.0.1).
1615
1616instaweb.modulepath::
1617        The default module path for linkgit:git-instaweb[1] to use
1618        instead of /usr/lib/apache2/modules.  Only used if httpd
1619        is Apache.
1620
1621instaweb.port::
1622        The port number to bind the gitweb httpd to. See
1623        linkgit:git-instaweb[1].
1624
1625interactive.singlekey::
1626        In interactive commands, allow the user to provide one-letter
1627        input with a single key (i.e., without hitting enter).
1628        Currently this is used by the `--patch` mode of
1629        linkgit:git-add[1], linkgit:git-checkout[1], linkgit:git-commit[1],
1630        linkgit:git-reset[1], and linkgit:git-stash[1]. Note that this
1631        setting is silently ignored if portable keystroke input
1632        is not available.
1633
1634log.abbrevCommit::
1635        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
1636        linkgit:git-whatchanged[1] assume `--abbrev-commit`. You may
1637        override this option with `--no-abbrev-commit`.
1638
1639log.date::
1640        Set the default date-time mode for the 'log' command.
1641        Setting a value for log.date is similar to using 'git log''s
1642        `--date` option.  Possible values are `relative`, `local`,
1643        `default`, `iso`, `rfc`, and `short`; see linkgit:git-log[1]
1644        for details.
1645
1646log.decorate::
1647        Print out the ref names of any commits that are shown by the log
1648        command. If 'short' is specified, the ref name prefixes 'refs/heads/',
1649        'refs/tags/' and 'refs/remotes/' will not be printed. If 'full' is
1650        specified, the full ref name (including prefix) will be printed.
1651        This is the same as the log commands '--decorate' option.
1652
1653log.showroot::
1654        If true, the initial commit will be shown as a big creation event.
1655        This is equivalent to a diff against an empty tree.
1656        Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
1657        normally hide the root commit will now show it. True by default.
1658
1659log.mailmap::
1660        If true, makes linkgit:git-log[1], linkgit:git-show[1], and
1661        linkgit:git-whatchanged[1] assume `--use-mailmap`.
1662
1663mailmap.file::
1664        The location of an augmenting mailmap file. The default
1665        mailmap, located in the root of the repository, is loaded
1666        first, then the mailmap file pointed to by this variable.
1667        The location of the mailmap file may be in a repository
1668        subdirectory, or somewhere outside of the repository itself.
1669        See linkgit:git-shortlog[1] and linkgit:git-blame[1].
1670
1671mailmap.blob::
1672        Like `mailmap.file`, but consider the value as a reference to a
1673        blob in the repository. If both `mailmap.file` and
1674        `mailmap.blob` are given, both are parsed, with entries from
1675        `mailmap.file` taking precedence. In a bare repository, this
1676        defaults to `HEAD:.mailmap`. In a non-bare repository, it
1677        defaults to empty.
1678
1679man.viewer::
1680        Specify the programs that may be used to display help in the
1681        'man' format. See linkgit:git-help[1].
1682
1683man.<tool>.cmd::
1684        Specify the command to invoke the specified man viewer. The
1685        specified command is evaluated in shell with the man page
1686        passed as argument. (See linkgit:git-help[1].)
1687
1688man.<tool>.path::
1689        Override the path for the given tool that may be used to
1690        display help in the 'man' format. See linkgit:git-help[1].
1691
1692include::merge-config.txt[]
1693
1694mergetool.<tool>.path::
1695        Override the path for the given tool.  This is useful in case
1696        your tool is not in the PATH.
1697
1698mergetool.<tool>.cmd::
1699        Specify the command to invoke the specified merge tool.  The
1700        specified command is evaluated in shell with the following
1701        variables available: 'BASE' is the name of a temporary file
1702        containing the common base of the files to be merged, if available;
1703        'LOCAL' is the name of a temporary file containing the contents of
1704        the file on the current branch; 'REMOTE' is the name of a temporary
1705        file containing the contents of the file from the branch being
1706        merged; 'MERGED' contains the name of the file to which the merge
1707        tool should write the results of a successful merge.
1708
1709mergetool.<tool>.trustExitCode::
1710        For a custom merge command, specify whether the exit code of
1711        the merge command can be used to determine whether the merge was
1712        successful.  If this is not set to true then the merge target file
1713        timestamp is checked and the merge assumed to have been successful
1714        if the file has been updated, otherwise the user is prompted to
1715        indicate the success of the merge.
1716
1717mergetool.keepBackup::
1718        After performing a merge, the original file with conflict markers
1719        can be saved as a file with a `.orig` extension.  If this variable
1720        is set to `false` then this file is not preserved.  Defaults to
1721        `true` (i.e. keep the backup files).
1722
1723mergetool.keepTemporaries::
1724        When invoking a custom merge tool, Git uses a set of temporary
1725        files to pass to the tool. If the tool returns an error and this
1726        variable is set to `true`, then these temporary files will be
1727        preserved, otherwise they will be removed after the tool has
1728        exited. Defaults to `false`.
1729
1730mergetool.prompt::
1731        Prompt before each invocation of the merge resolution program.
1732
1733notes.displayRef::
1734        The (fully qualified) refname from which to show notes when
1735        showing commit messages.  The value of this variable can be set
1736        to a glob, in which case notes from all matching refs will be
1737        shown.  You may also specify this configuration variable
1738        several times.  A warning will be issued for refs that do not
1739        exist, but a glob that does not match any refs is silently
1740        ignored.
1741+
1742This setting can be overridden with the `GIT_NOTES_DISPLAY_REF`
1743environment variable, which must be a colon separated list of refs or
1744globs.
1745+
1746The effective value of "core.notesRef" (possibly overridden by
1747GIT_NOTES_REF) is also implicitly added to the list of refs to be
1748displayed.
1749
1750notes.rewrite.<command>::
1751        When rewriting commits with <command> (currently `amend` or
1752        `rebase`) and this variable is set to `true`, Git
1753        automatically copies your notes from the original to the
1754        rewritten commit.  Defaults to `true`, but see
1755        "notes.rewriteRef" below.
1756
1757notes.rewriteMode::
1758        When copying notes during a rewrite (see the
1759        "notes.rewrite.<command>" option), determines what to do if
1760        the target commit already has a note.  Must be one of
1761        `overwrite`, `concatenate`, or `ignore`.  Defaults to
1762        `concatenate`.
1763+
1764This setting can be overridden with the `GIT_NOTES_REWRITE_MODE`
1765environment variable.
1766
1767notes.rewriteRef::
1768        When copying notes during a rewrite, specifies the (fully
1769        qualified) ref whose notes should be copied.  The ref may be a
1770        glob, in which case notes in all matching refs will be copied.
1771        You may also specify this configuration several times.
1772+
1773Does not have a default value; you must configure this variable to
1774enable note rewriting.  Set it to `refs/notes/commits` to enable
1775rewriting for the default commit notes.
1776+
1777This setting can be overridden with the `GIT_NOTES_REWRITE_REF`
1778environment variable, which must be a colon separated list of refs or
1779globs.
1780
1781pack.window::
1782        The size of the window used by linkgit:git-pack-objects[1] when no
1783        window size is given on the command line. Defaults to 10.
1784
1785pack.depth::
1786        The maximum delta depth used by linkgit:git-pack-objects[1] when no
1787        maximum depth is given on the command line. Defaults to 50.
1788
1789pack.windowMemory::
1790        The window memory size limit used by linkgit:git-pack-objects[1]
1791        when no limit is given on the command line.  The value can be
1792        suffixed with "k", "m", or "g".  Defaults to 0, meaning no
1793        limit.
1794
1795pack.compression::
1796        An integer -1..9, indicating the compression level for objects
1797        in a pack file. -1 is the zlib default. 0 means no
1798        compression, and 1..9 are various speed/size tradeoffs, 9 being
1799        slowest.  If not set,  defaults to core.compression.  If that is
1800        not set,  defaults to -1, the zlib default, which is "a default
1801        compromise between speed and compression (currently equivalent
1802        to level 6)."
1803+
1804Note that changing the compression level will not automatically recompress
1805all existing objects. You can force recompression by passing the -F option
1806to linkgit:git-repack[1].
1807
1808pack.deltaCacheSize::
1809        The maximum memory in bytes used for caching deltas in
1810        linkgit:git-pack-objects[1] before writing them out to a pack.
1811        This cache is used to speed up the writing object phase by not
1812        having to recompute the final delta result once the best match
1813        for all objects is found.  Repacking large repositories on machines
1814        which are tight with memory might be badly impacted by this though,
1815        especially if this cache pushes the system into swapping.
1816        A value of 0 means no limit. The smallest size of 1 byte may be
1817        used to virtually disable this cache. Defaults to 256 MiB.
1818
1819pack.deltaCacheLimit::
1820        The maximum size of a delta, that is cached in
1821        linkgit:git-pack-objects[1]. This cache is used to speed up the
1822        writing object phase by not having to recompute the final delta
1823        result once the best match for all objects is found. Defaults to 1000.
1824
1825pack.threads::
1826        Specifies the number of threads to spawn when searching for best
1827        delta matches.  This requires that linkgit:git-pack-objects[1]
1828        be compiled with pthreads otherwise this option is ignored with a
1829        warning. This is meant to reduce packing time on multiprocessor
1830        machines. The required amount of memory for the delta search window
1831        is however multiplied by the number of threads.
1832        Specifying 0 will cause Git to auto-detect the number of CPU's
1833        and set the number of threads accordingly.
1834
1835pack.indexVersion::
1836        Specify the default pack index version.  Valid values are 1 for
1837        legacy pack index used by Git versions prior to 1.5.2, and 2 for
1838        the new pack index with capabilities for packs larger than 4 GB
1839        as well as proper protection against the repacking of corrupted
1840        packs.  Version 2 is the default.  Note that version 2 is enforced
1841        and this config option ignored whenever the corresponding pack is
1842        larger than 2 GB.
1843+
1844If you have an old Git that does not understand the version 2 `*.idx` file,
1845cloning or fetching over a non native protocol (e.g. "http" and "rsync")
1846that will copy both `*.pack` file and corresponding `*.idx` file from the
1847other side may give you a repository that cannot be accessed with your
1848older version of Git. If the `*.pack` file is smaller than 2 GB, however,
1849you can use linkgit:git-index-pack[1] on the *.pack file to regenerate
1850the `*.idx` file.
1851
1852pack.packSizeLimit::
1853        The maximum size of a pack.  This setting only affects
1854        packing to a file when repacking, i.e. the git:// protocol
1855        is unaffected.  It can be overridden by the `--max-pack-size`
1856        option of linkgit:git-repack[1]. The minimum size allowed is
1857        limited to 1 MiB. The default is unlimited.
1858        Common unit suffixes of 'k', 'm', or 'g' are
1859        supported.
1860
1861pager.<cmd>::
1862        If the value is boolean, turns on or off pagination of the
1863        output of a particular Git subcommand when writing to a tty.
1864        Otherwise, turns on pagination for the subcommand using the
1865        pager specified by the value of `pager.<cmd>`.  If `--paginate`
1866        or `--no-pager` is specified on the command line, it takes
1867        precedence over this option.  To disable pagination for all
1868        commands, set `core.pager` or `GIT_PAGER` to `cat`.
1869
1870pretty.<name>::
1871        Alias for a --pretty= format string, as specified in
1872        linkgit:git-log[1]. Any aliases defined here can be used just
1873        as the built-in pretty formats could. For example,
1874        running `git config pretty.changelog "format:* %H %s"`
1875        would cause the invocation `git log --pretty=changelog`
1876        to be equivalent to running `git log "--pretty=format:* %H %s"`.
1877        Note that an alias with the same name as a built-in format
1878        will be silently ignored.
1879
1880pull.rebase::
1881        When true, rebase branches on top of the fetched branch, instead
1882        of merging the default branch from the default remote when "git
1883        pull" is run. See "branch.<name>.rebase" for setting this on a
1884        per-branch basis.
1885+
1886        When preserve, also pass `--preserve-merges` along to 'git rebase'
1887        so that locally committed merge commits will not be flattened
1888        by running 'git pull'.
1889+
1890*NOTE*: this is a possibly dangerous operation; do *not* use
1891it unless you understand the implications (see linkgit:git-rebase[1]
1892for details).
1893
1894pull.octopus::
1895        The default merge strategy to use when pulling multiple branches
1896        at once.
1897
1898pull.twohead::
1899        The default merge strategy to use when pulling a single branch.
1900
1901push.default::
1902        Defines the action `git push` should take if no refspec is
1903        explicitly given.  Different values are well-suited for
1904        specific workflows; for instance, in a purely central workflow
1905        (i.e. the fetch source is equal to the push destination),
1906        `upstream` is probably what you want.  Possible values are:
1907+
1908--
1909
1910* `nothing` - do not push anything (error out) unless a refspec is
1911  explicitly given. This is primarily meant for people who want to
1912  avoid mistakes by always being explicit.
1913
1914* `current` - push the current branch to update a branch with the same
1915  name on the receiving end.  Works in both central and non-central
1916  workflows.
1917
1918* `upstream` - push the current branch back to the branch whose
1919  changes are usually integrated into the current branch (which is
1920  called `@{upstream}`).  This mode only makes sense if you are
1921  pushing to the same repository you would normally pull from
1922  (i.e. central workflow).
1923
1924* `simple` - in centralized workflow, work like `upstream` with an
1925  added safety to refuse to push if the upstream branch's name is
1926  different from the local one.
1927+
1928When pushing to a remote that is different from the remote you normally
1929pull from, work as `current`.  This is the safest option and is suited
1930for beginners.
1931+
1932This mode will become the default in Git 2.0.
1933
1934* `matching` - push all branches having the same name on both ends.
1935  This makes the repository you are pushing to remember the set of
1936  branches that will be pushed out (e.g. if you always push 'maint'
1937  and 'master' there and no other branches, the repository you push
1938  to will have these two branches, and your local 'maint' and
1939  'master' will be pushed there).
1940+
1941To use this mode effectively, you have to make sure _all_ the
1942branches you would push out are ready to be pushed out before
1943running 'git push', as the whole point of this mode is to allow you
1944to push all of the branches in one go.  If you usually finish work
1945on only one branch and push out the result, while other branches are
1946unfinished, this mode is not for you.  Also this mode is not
1947suitable for pushing into a shared central repository, as other
1948people may add new branches there, or update the tip of existing
1949branches outside your control.
1950+
1951This is currently the default, but Git 2.0 will change the default
1952to `simple`.
1953
1954--
1955
1956rebase.stat::
1957        Whether to show a diffstat of what changed upstream since the last
1958        rebase. False by default.
1959
1960rebase.autosquash::
1961        If set to true enable '--autosquash' option by default.
1962
1963rebase.autostash::
1964        When set to true, automatically create a temporary stash
1965        before the operation begins, and apply it after the operation
1966        ends.  This means that you can run rebase on a dirty worktree.
1967        However, use with care: the final stash application after a
1968        successful rebase might result in non-trivial conflicts.
1969        Defaults to false.
1970
1971receive.autogc::
1972        By default, git-receive-pack will run "git-gc --auto" after
1973        receiving data from git-push and updating refs.  You can stop
1974        it by setting this variable to false.
1975
1976receive.fsckObjects::
1977        If it is set to true, git-receive-pack will check all received
1978        objects. It will abort in the case of a malformed object or a
1979        broken link. The result of an abort are only dangling objects.
1980        Defaults to false. If not set, the value of `transfer.fsckObjects`
1981        is used instead.
1982
1983receive.unpackLimit::
1984        If the number of objects received in a push is below this
1985        limit then the objects will be unpacked into loose object
1986        files. However if the number of received objects equals or
1987        exceeds this limit then the received pack will be stored as
1988        a pack, after adding any missing delta bases.  Storing the
1989        pack from a push can make the push operation complete faster,
1990        especially on slow filesystems.  If not set, the value of
1991        `transfer.unpackLimit` is used instead.
1992
1993receive.denyDeletes::
1994        If set to true, git-receive-pack will deny a ref update that deletes
1995        the ref. Use this to prevent such a ref deletion via a push.
1996
1997receive.denyDeleteCurrent::
1998        If set to true, git-receive-pack will deny a ref update that
1999        deletes the currently checked out branch of a non-bare repository.
2000
2001receive.denyCurrentBranch::
2002        If set to true or "refuse", git-receive-pack will deny a ref update
2003        to the currently checked out branch of a non-bare repository.
2004        Such a push is potentially dangerous because it brings the HEAD
2005        out of sync with the index and working tree. If set to "warn",
2006        print a warning of such a push to stderr, but allow the push to
2007        proceed. If set to false or "ignore", allow such pushes with no
2008        message. Defaults to "refuse".
2009
2010receive.denyNonFastForwards::
2011        If set to true, git-receive-pack will deny a ref update which is
2012        not a fast-forward. Use this to prevent such an update via a push,
2013        even if that push is forced. This configuration variable is
2014        set when initializing a shared repository.
2015
2016receive.hiderefs::
2017        String(s) `receive-pack` uses to decide which refs to omit
2018        from its initial advertisement.  Use more than one
2019        definitions to specify multiple prefix strings. A ref that
2020        are under the hierarchies listed on the value of this
2021        variable is excluded, and is hidden when responding to `git
2022        push`, and an attempt to update or delete a hidden ref by
2023        `git push` is rejected.
2024
2025receive.updateserverinfo::
2026        If set to true, git-receive-pack will run git-update-server-info
2027        after receiving data from git-push and updating refs.
2028
2029remote.pushdefault::
2030        The remote to push to by default.  Overrides
2031        `branch.<name>.remote` for all branches, and is overridden by
2032        `branch.<name>.pushremote` for specific branches.
2033
2034remote.<name>.url::
2035        The URL of a remote repository.  See linkgit:git-fetch[1] or
2036        linkgit:git-push[1].
2037
2038remote.<name>.pushurl::
2039        The push URL of a remote repository.  See linkgit:git-push[1].
2040
2041remote.<name>.proxy::
2042        For remotes that require curl (http, https and ftp), the URL to
2043        the proxy to use for that remote.  Set to the empty string to
2044        disable proxying for that remote.
2045
2046remote.<name>.fetch::
2047        The default set of "refspec" for linkgit:git-fetch[1]. See
2048        linkgit:git-fetch[1].
2049
2050remote.<name>.push::
2051        The default set of "refspec" for linkgit:git-push[1]. See
2052        linkgit:git-push[1].
2053
2054remote.<name>.mirror::
2055        If true, pushing to this remote will automatically behave
2056        as if the `--mirror` option was given on the command line.
2057
2058remote.<name>.skipDefaultUpdate::
2059        If true, this remote will be skipped by default when updating
2060        using linkgit:git-fetch[1] or the `update` subcommand of
2061        linkgit:git-remote[1].
2062
2063remote.<name>.skipFetchAll::
2064        If true, this remote will be skipped by default when updating
2065        using linkgit:git-fetch[1] or the `update` subcommand of
2066        linkgit:git-remote[1].
2067
2068remote.<name>.receivepack::
2069        The default program to execute on the remote side when pushing.  See
2070        option \--receive-pack of linkgit:git-push[1].
2071
2072remote.<name>.uploadpack::
2073        The default program to execute on the remote side when fetching.  See
2074        option \--upload-pack of linkgit:git-fetch-pack[1].
2075
2076remote.<name>.tagopt::
2077        Setting this value to \--no-tags disables automatic tag following when
2078        fetching from remote <name>. Setting it to \--tags will fetch every
2079        tag from remote <name>, even if they are not reachable from remote
2080        branch heads. Passing these flags directly to linkgit:git-fetch[1] can
2081        override this setting. See options \--tags and \--no-tags of
2082        linkgit:git-fetch[1].
2083
2084remote.<name>.vcs::
2085        Setting this to a value <vcs> will cause Git to interact with
2086        the remote with the git-remote-<vcs> helper.
2087
2088remote.<name>.prune::
2089        When set to true, fetching from this remote by default will also
2090        remove any remote-tracking branches which no longer exist on the
2091        remote (as if the `--prune` option was give on the command line).
2092        Overrides `fetch.prune` settings, if any.
2093
2094remotes.<group>::
2095        The list of remotes which are fetched by "git remote update
2096        <group>".  See linkgit:git-remote[1].
2097
2098repack.usedeltabaseoffset::
2099        By default, linkgit:git-repack[1] creates packs that use
2100        delta-base offset. If you need to share your repository with
2101        Git older than version 1.4.4, either directly or via a dumb
2102        protocol such as http, then you need to set this option to
2103        "false" and repack. Access from old Git versions over the
2104        native protocol are unaffected by this option.
2105
2106rerere.autoupdate::
2107        When set to true, `git-rerere` updates the index with the
2108        resulting contents after it cleanly resolves conflicts using
2109        previously recorded resolution.  Defaults to false.
2110
2111rerere.enabled::
2112        Activate recording of resolved conflicts, so that identical
2113        conflict hunks can be resolved automatically, should they be
2114        encountered again.  By default, linkgit:git-rerere[1] is
2115        enabled if there is an `rr-cache` directory under the
2116        `$GIT_DIR`, e.g. if "rerere" was previously used in the
2117        repository.
2118
2119sendemail.identity::
2120        A configuration identity. When given, causes values in the
2121        'sendemail.<identity>' subsection to take precedence over
2122        values in the 'sendemail' section. The default identity is
2123        the value of 'sendemail.identity'.
2124
2125sendemail.smtpencryption::
2126        See linkgit:git-send-email[1] for description.  Note that this
2127        setting is not subject to the 'identity' mechanism.
2128
2129sendemail.smtpssl::
2130        Deprecated alias for 'sendemail.smtpencryption = ssl'.
2131
2132sendemail.smtpsslcertpath::
2133        Path to ca-certificates (either a directory or a single file).
2134        Set it to an empty string to disable certificate verification.
2135
2136sendemail.<identity>.*::
2137        Identity-specific versions of the 'sendemail.*' parameters
2138        found below, taking precedence over those when the this
2139        identity is selected, through command-line or
2140        'sendemail.identity'.
2141
2142sendemail.aliasesfile::

2166
2167sendemail.signedoffcc::
2168        Deprecated alias for 'sendemail.signedoffbycc'.
2169
2170showbranch.default::
2171        The default set of branches for linkgit:git-show-branch[1].
2172        See linkgit:git-show-branch[1].
2173
2174status.relativePaths::
2175        By default, linkgit:git-status[1] shows paths relative to the
2176        current directory. Setting this variable to `false` shows paths
2177        relative to the repository root (this was the default for Git
2178        prior to v1.5.4).
2179
2180status.short::
2181        Set to true to enable --short by default in linkgit:git-status[1].
2182        The option --no-short takes precedence over this variable.
2183
2184status.branch::
2185        Set to true to enable --branch by default in linkgit:git-status[1].
2186        The option --no-branch takes precedence over this variable.
2187
2188status.displayCommentPrefix::
2189        If set to true, linkgit:git-status[1] will insert a comment
2190        prefix before each output line (starting with
2191        `core.commentChar`, i.e. `#` by default). This was the
2192        behavior of linkgit:git-status[1] in Git 1.8.4 and previous.
2193        Defaults to false.
2194
2195status.showUntrackedFiles::
2196        By default, linkgit:git-status[1] and linkgit:git-commit[1] show
2197        files which are not currently tracked by Git. Directories which
2198        contain only untracked files, are shown with the directory name
2199        only. Showing untracked files means that Git needs to lstat() all
2200        all the files in the whole repository, which might be slow on some
2201        systems. So, this variable controls how the commands displays
2202        the untracked files. Possible values are:
2203+
2204--
2205* `no` - Show no untracked files.
2206* `normal` - Show untracked files and directories.
2207* `all` - Show also individual files in untracked directories.
2208--
2209+
2210If this variable is not specified, it defaults to 'normal'.
2211This variable can be overridden with the -u|--untracked-files option
2212of linkgit:git-status[1] and linkgit:git-commit[1].
2213
2214status.submodulesummary::
2215        Defaults to false.
2216        If this is set to a non zero number or true (identical to -1 or an
2217        unlimited number), the submodule summary will be enabled and a
2218        summary of commits for modified submodules will be shown (see
2219        --summary-limit option of linkgit:git-submodule[1]). Please note
2220        that the summary output command will be suppressed for all
2221        submodules when `diff.ignoreSubmodules` is set to 'all' or only
2222        for those submodules where `submodule.<name>.ignore=all`. To
2223        also view the summary for ignored submodules you can either use
2224        the --ignore-submodules=dirty command line option or the 'git
2225        submodule summary' command, which shows a similar output but does
2226        not honor these settings.
2227
2228submodule.<name>.path::
2229submodule.<name>.url::
2230submodule.<name>.update::
2231        The path within this project, URL, and the updating strategy
2232        for a submodule.  These variables are initially populated
2233        by 'git submodule init'; edit them to override the
2234        URL and other values found in the `.gitmodules` file.  See
2235        linkgit:git-submodule[1] and linkgit:gitmodules[5] for details.
2236
2237submodule.<name>.branch::
2238        The remote branch name for a submodule, used by `git submodule
2239        update --remote`.  Set this option to override the value found in
2240        the `.gitmodules` file.  See linkgit:git-submodule[1] and
2241        linkgit:gitmodules[5] for details.
2242
2243submodule.<name>.fetchRecurseSubmodules::
2244        This option can be used to control recursive fetching of this
2245        submodule. It can be overridden by using the --[no-]recurse-submodules
2246        command line option to "git fetch" and "git pull".
2247        This setting will override that from in the linkgit:gitmodules[5]
2248        file.
2249
2250submodule.<name>.ignore::
2251        Defines under what circumstances "git status" and the diff family show
2252        a submodule as modified. When set to "all", it will never be considered
2253        modified, "dirty" will ignore all changes to the submodules work tree and
2254        takes only differences between the HEAD of the submodule and the commit
2255        recorded in the superproject into account. "untracked" will additionally
2256        let submodules with modified tracked files in their work tree show up.
2257        Using "none" (the default when this option is not set) also shows
2258        submodules that have untracked files in their work tree as changed.
2259        This setting overrides any setting made in .gitmodules for this submodule,
2260        both settings can be overridden on the command line by using the
2261        "--ignore-submodules" option. The 'git submodule' commands are not
2262        affected by this setting.
2263
2264tar.umask::
2265        This variable can be used to restrict the permission bits of
2266        tar archive entries.  The default is 0002, which turns off the
2267        world write bit.  The special value "user" indicates that the
2268        archiving user's umask will be used instead.  See umask(2) and
2269        linkgit:git-archive[1].
2270
2271transfer.fsckObjects::
2272        When `fetch.fsckObjects` or `receive.fsckObjects` are
2273        not set, the value of this variable is used instead.
2274        Defaults to false.
2275
2276transfer.hiderefs::
2277        This variable can be used to set both `receive.hiderefs`
2278        and `uploadpack.hiderefs` at the same time to the same
2279        values.  See entries for these other variables.
2280
2281transfer.unpackLimit::
2282        When `fetch.unpackLimit` or `receive.unpackLimit` are
2283        not set, the value of this variable is used instead.
2284        The default value is 100.
2285
2286uploadpack.hiderefs::
2287        String(s) `upload-pack` uses to decide which refs to omit
2288        from its initial advertisement.  Use more than one
2289        definitions to specify multiple prefix strings. A ref that
2290        are under the hierarchies listed on the value of this
2291        variable is excluded, and is hidden from `git ls-remote`,
2292        `git fetch`, etc.  An attempt to fetch a hidden ref by `git
2293        fetch` will fail.  See also `uploadpack.allowtipsha1inwant`.
2294
2295uploadpack.allowtipsha1inwant::
2296        When `uploadpack.hiderefs` is in effect, allow `upload-pack`
2297        to accept a fetch request that asks for an object at the tip
2298        of a hidden ref (by default, such a request is rejected).
2299        see also `uploadpack.hiderefs`.
2300
2301uploadpack.keepalive::
2302        When `upload-pack` has started `pack-objects`, there may be a
2303        quiet period while `pack-objects` prepares the pack. Normally
2304        it would output progress information, but if `--quiet` was used
2305        for the fetch, `pack-objects` will output nothing at all until
2306        the pack data begins. Some clients and networks may consider
2307        the server to be hung and give up. Setting this option instructs
2308        `upload-pack` to send an empty keepalive packet every
2309        `uploadpack.keepalive` seconds. Setting this option to 0
2310        disables keepalive packets entirely. The default is 5 seconds.
2311
2312url.<base>.insteadOf::
2313        Any URL that starts with this value will be rewritten to
2314        start, instead, with <base>. In cases where some site serves a
2315        large number of repositories, and serves them with multiple
2316        access methods, and some users need to use different access
2317        methods, this feature allows people to specify any of the
2318        equivalent URLs and have Git automatically rewrite the URL to
2319        the best alternative for the particular user, even for a
2320        never-before-seen repository on the site.  When more than one
2321        insteadOf strings match a given URL, the longest match is used.
2322
2323url.<base>.pushInsteadOf::
2324        Any URL that starts with this value will not be pushed to;
2325        instead, it will be rewritten to start with <base>, and the
2326        resulting URL will be pushed to. In cases where some site serves
2327        a large number of repositories, and serves them with multiple
2328        access methods, some of which do not allow push, this feature
2329        allows people to specify a pull-only URL and have Git
2330        automatically use an appropriate URL to push, even for a
2331        never-before-seen repository on the site.  When more than one
2332        pushInsteadOf strings match a given URL, the longest match is
2333        used.  If a remote has an explicit pushurl, Git will ignore this
2334        setting for that remote.
2335
2336user.email::
2337        Your email address to be recorded in any newly created commits.
2338        Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and
2339        'EMAIL' environment variables.  See linkgit:git-commit-tree[1].
2340
2341user.name::
2342        Your full name to be recorded in any newly created commits.
2343        Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
2344        environment variables.  See linkgit:git-commit-tree[1].
2345
2346user.signingkey::
2347        If linkgit:git-tag[1] or linkgit:git-commit[1] is not selecting the
2348        key you want it to automatically when creating a signed tag or
2349        commit, you can override the default selection with this variable.
2350        This option is passed unchanged to gpg's --local-user parameter,
2351        so you may specify a key using any method that gpg supports.
2352
2353web.browser::
2354        Specify a web browser that may be used by some commands.
2355        Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
2356        may use it.
