Documentation / config.txton commit bisect: add "git bisect help" subcommand to get a long usage string (243a60f)
   1CONFIGURATION FILE
   2------------------
   3
   4The git configuration file contains a number of variables that affect
   5the git command's behavior. `.git/config` file for each repository
   6is used to store the information for that repository, and
   7`$HOME/.gitconfig` is used to store per user information to give
   8fallback values for `.git/config` file. The file `/etc/gitconfig`
   9can be used to store system-wide defaults.
  10
  11They can be used by both the git plumbing
  12and the porcelains. The variables are divided into sections, where
  13in the fully qualified variable name 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 and only alphanumeric
  16characters are allowed. Some variables may appear multiple times.
  17
  18Syntax
  19~~~~~~
  20
  21The syntax is fairly flexible and permissive; whitespaces are mostly
  22ignored.  The '#' and ';' characters begin comments to the end of line,
  23blank lines are ignored.
  24
  25The file consists of sections and variables.  A section begins with
  26the name of the section in square brackets and continues until the next
  27section begins.  Section names are not case sensitive.  Only alphanumeric
  28characters, '`-`' and '`.`' are allowed in section names.  Each variable
  29must belong to some section, which means that there must be section
  30header before first setting of a variable.
  31
  32Sections can be further divided into subsections.  To begin a subsection
  33put its name in double quotes, separated by space from the section name,
  34in the section header, like in example below:
  35
  36--------
  37        [section "subsection"]
  38
  39--------
  40
  41Subsection names can contain any characters except newline (doublequote
  42'`"`' and backslash have to be escaped as '`\"`' and '`\\`',
  43respectively) and are case sensitive.  Section header cannot span multiple
  44lines.  Variables may belong directly to a section or to a given subsection.
  45You can have `[section]` if you have `[section "subsection"]`, but you
  46don't need to.
  47
  48There is also (case insensitive) alternative `[section.subsection]` syntax.
  49In this syntax subsection names follow the same restrictions as for section
  50name.
  51
  52All the other lines are recognized as setting variables, in the form
  53'name = value'.  If there is no equal sign on the line, the entire line
  54is taken as 'name' and the variable is recognized as boolean "true".
  55The variable names are case-insensitive and only alphanumeric
  56characters and '`-`' are allowed.  There can be more than one value
  57for a given variable; we say then that variable is multivalued.
  58
  59Leading and trailing whitespace in a variable value is discarded.
  60Internal whitespace within a variable value is retained verbatim.
  61
  62The values following the equals sign in variable assign are all either
  63a string, an integer, or a boolean.  Boolean values may be given as yes/no,
  640/1 or true/false.  Case is not significant in boolean values, when
  65converting value to the canonical form using '--bool' type specifier;
  66`git-config` will ensure that the output is "true" or "false".
  67
  68String values may be entirely or partially enclosed in double quotes.
  69You need to enclose variable value in double quotes if you want to
  70preserve leading or trailing whitespace, or if variable value contains
  71beginning of comment characters (if it contains '#' or ';').
  72Double quote '`"`' and backslash '`\`' characters in variable value must
  73be escaped: use '`\"`' for '`"`' and '`\\`' for '`\`'.
  74
  75The following escape sequences (beside '`\"`' and '`\\`') are recognized:
  76'`\n`' for newline character (NL), '`\t`' for horizontal tabulation (HT, TAB)
  77and '`\b`' for backspace (BS).  No other char escape sequence, nor octal
  78char sequences are valid.
  79
  80Variable value ending in a '`\`' is continued on the next line in the
  81customary UNIX fashion.
  82
  83Some variables may require special value format.

 106
 107Variables
 108~~~~~~~~~
 109
 110Note that this list is non-comprehensive and not necessarily complete.
 111For command-specific variables, you will find a more detailed description
 112in the appropriate manual page. You will find a description of non-core
 113porcelain configuration variables in the respective porcelain documentation.
 114
 115core.fileMode::
 116        If false, the executable bit differences between the index and
 117        the working copy are ignored; useful on broken filesystems like FAT.
 118        See linkgit:git-update-index[1]. True by default.
 119
 120core.quotepath::
 121        The commands that output paths (e.g. `ls-files`,
 122        `diff`), when not given the `-z` option, will quote
 123        "unusual" characters in the pathname by enclosing the
 124        pathname in a double-quote pair and with backslashes the
 125        same way strings in C source code are quoted.  If this
 126        variable is set to false, the bytes higher than 0x80 are
 127        not quoted but output as verbatim.  Note that double
 128        quote, backslash and control characters are always
 129        quoted without `-z` regardless of the setting of this
 130        variable.
 131
 132core.autocrlf::
 133        If true, makes git convert `CRLF` at the end of lines in text files to
 134        `LF` when reading from the filesystem, and convert in reverse when
 135        writing to the filesystem.  The variable can be set to
 136        'input', in which case the conversion happens only while
 137        reading from the filesystem but files are written out with
 138        `LF` at the end of lines.  Currently, which paths to consider
 139        "text" (i.e. be subjected to the autocrlf mechanism) is
 140        decided purely based on the contents.
 141
 142core.safecrlf::
 143        If true, makes git check if converting `CRLF` as controlled by
 144        `core.autocrlf` is reversible.  Git will verify if a command
 145        modifies a file in the work tree either directly or indirectly.
 146        For example, committing a file followed by checking out the
 147        same file should yield the original file in the work tree.  If
 148        this is not the case for the current setting of
 149        `core.autocrlf`, git will reject the file.  The variable can
 150        be set to "warn", in which case git will only warn about an
 151        irreversible conversion but continue the operation.
 152+
 153CRLF conversion bears a slight chance of corrupting data.
 154autocrlf=true will convert CRLF to LF during commit and LF to
 155CRLF during checkout.  A file that contains a mixture of LF and
 156CRLF before the commit cannot be recreated by git.  For text
 157files this is the right thing to do: it corrects line endings
 158such that we have only LF line endings in the repository.
 159But for binary files that are accidentally classified as text the
 160conversion can corrupt data.
 161+
 162If you recognize such corruption early you can easily fix it by
 163setting the conversion type explicitly in .gitattributes.  Right
 164after committing you still have the original file in your work
 165tree and this file is not yet corrupted.  You can explicitly tell
 166git that this file is binary and git will handle the file
 167appropriately.
 168+
 169Unfortunately, the desired effect of cleaning up text files with
 170mixed line endings and the undesired effect of corrupting binary
 171files cannot be distinguished.  In both cases CRLFs are removed
 172in an irreversible way.  For text files this is the right thing
 173to do because CRLFs are line endings, while for binary files
 174converting CRLFs corrupts data.
 175+
 176Note, this safety check does not mean that a checkout will generate a
 177file identical to the original file for a different setting of
 178`core.autocrlf`, but only for the current one.  For example, a text
 179file with `LF` would be accepted with `core.autocrlf=input` and could
 180later be checked out with `core.autocrlf=true`, in which case the
 181resulting file would contain `CRLF`, although the original file
 182contained `LF`.  However, in both work trees the line endings would be
 183consistent, that is either all `LF` or all `CRLF`, but never mixed.  A
 184file with mixed line endings would be reported by the `core.safecrlf`
 185mechanism.
 186
 187core.symlinks::
 188        If false, symbolic links are checked out as small plain files that
 189        contain the link text. linkgit:git-update-index[1] and
 190        linkgit:git-add[1] will not change the recorded type to regular
 191        file. Useful on filesystems like FAT that do not support
 192        symbolic links. True by default.
 193
 194core.gitProxy::
 195        A "proxy command" to execute (as 'command host port') instead
 196        of establishing direct connection to the remote server when
 197        using the git protocol for fetching. If the variable value is
 198        in the "COMMAND for DOMAIN" format, the command is applied only
 199        on hostnames ending with the specified domain string. This variable
 200        may be set multiple times and is matched in the given order;
 201        the first match wins.
 202+
 203Can be overridden by the 'GIT_PROXY_COMMAND' environment variable
 204(which always applies universally, without the special "for"
 205handling).
 206
 207core.ignoreStat::
 208        The working copy files are assumed to stay unchanged until you
 209        mark them otherwise manually - Git will not detect the file changes
 210        by lstat() calls. This is useful on systems where those are very
 211        slow, such as Microsoft Windows.  See linkgit:git-update-index[1].
 212        False by default.
 213
 214core.preferSymlinkRefs::
 215        Instead of the default "symref" format for HEAD
 216        and other symbolic reference files, use symbolic links.
 217        This is sometimes needed to work with old scripts that
 218        expect HEAD to be a symbolic link.
 219
 220core.bare::
 221        If true this repository is assumed to be 'bare' and has no
 222        working directory associated with it.  If this is the case a
 223        number of commands that require a working directory will be
 224        disabled, such as linkgit:git-add[1] or linkgit:git-merge[1].
 225+
 226This setting is automatically guessed by linkgit:git-clone[1] or
 227linkgit:git-init[1] when the repository was created.  By default a
 228repository that ends in "/.git" is assumed to be not bare (bare =
 229false), while all other repositories are assumed to be bare (bare
 230= true).
 231
 232core.worktree::
 233        Set the path to the working tree.  The value will not be
 234        used in combination with repositories found automatically in
 235        a .git directory (i.e. $GIT_DIR is not set).
 236        This can be overridden by the GIT_WORK_TREE environment
 237        variable and the '--work-tree' command line option.
 238
 239core.logAllRefUpdates::
 240        Enable the reflog. Updates to a ref <ref> is logged to the file
 241        "$GIT_DIR/logs/<ref>", by appending the new and old
 242        SHA1, the date/time and the reason of the update, but
 243        only when the file exists.  If this configuration
 244        variable is set to true, missing "$GIT_DIR/logs/<ref>"
 245        file is automatically created for branch heads.
 246+
 247This information can be used to determine what commit
 248was the tip of a branch "2 days ago".
 249+
 250This value is true by default in a repository that has
 251a working directory associated with it, and false by
 252default in a bare repository.
 253
 254core.repositoryFormatVersion::
 255        Internal variable identifying the repository format and layout
 256        version.
 257
 258core.sharedRepository::
 259        When 'group' (or 'true'), the repository is made shareable between
 260        several users in a group (making sure all the files and objects are
 261        group-writable). When 'all' (or 'world' or 'everybody'), the
 262        repository will be readable by all users, additionally to being
 263        group-shareable. When 'umask' (or 'false'), git will use permissions
 264        reported by umask(2). See linkgit:git-init[1]. False by default.
 265
 266core.warnAmbiguousRefs::
 267        If true, git will warn you if the ref name you passed it is ambiguous
 268        and might match multiple refs in the .git/refs/ tree. True by default.
 269
 270core.compression::
 271        An integer -1..9, indicating a default compression level.
 272        -1 is the zlib default. 0 means no compression,
 273        and 1..9 are various speed/size tradeoffs, 9 being slowest.
 274        If set, this provides a default to other compression variables,
 275        such as 'core.loosecompression' and 'pack.compression'.
 276
 277core.loosecompression::
 278        An integer -1..9, indicating the compression level for objects that
 279        are not in a pack file. -1 is the zlib default. 0 means no
 280        compression, and 1..9 are various speed/size tradeoffs, 9 being
 281        slowest.  If not set,  defaults to core.compression.  If that is
 282        not set,  defaults to 1 (best speed).
 283
 284core.packedGitWindowSize::
 285        Number of bytes of a pack file to map into memory in a
 286        single mapping operation.  Larger window sizes may allow
 287        your system to process a smaller number of large pack files
 288        more quickly.  Smaller window sizes will negatively affect
 289        performance due to increased calls to the operating system's
 290        memory manager, but may improve performance when accessing
 291        a large number of large pack files.
 292+
 293Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
 294MiB on 32 bit platforms and 1 GiB on 64 bit platforms.  This should
 295be reasonable for all users/operating systems.  You probably do
 296not need to adjust this value.
 297+
 298Common unit suffixes of 'k', 'm', or 'g' are supported.
 299
 300core.packedGitLimit::
 301        Maximum number of bytes to map simultaneously into memory
 302        from pack files.  If Git needs to access more than this many
 303        bytes at once to complete an operation it will unmap existing
 304        regions to reclaim virtual address space within the process.
 305+
 306Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms.
 307This should be reasonable for all users/operating systems, except on
 308the largest projects.  You probably do not need to adjust this value.
 309+
 310Common unit suffixes of 'k', 'm', or 'g' are supported.
 311
 312core.deltaBaseCacheLimit::
 313        Maximum number of bytes to reserve for caching base objects
 314        that multiple deltafied objects reference.  By storing the
 315        entire decompressed base objects in a cache Git is able
 316        to avoid unpacking and decompressing frequently used base
 317        objects multiple times.
 318+
 319Default is 16 MiB on all platforms.  This should be reasonable
 320for all users/operating systems, except on the largest projects.
 321You probably do not need to adjust this value.
 322+
 323Common unit suffixes of 'k', 'm', or 'g' are supported.
 324
 325core.excludesfile::
 326        In addition to '.gitignore' (per-directory) and
 327        '.git/info/exclude', git looks into this file for patterns
 328        of files which are not meant to be tracked.  See
 329        linkgit:gitignore[5].
 330
 331core.editor::
 332        Commands such as `commit` and `tag` that lets you edit
 333        messages by launching an editor uses the value of this
 334        variable when it is set, and the environment variable
 335        `GIT_EDITOR` is not set.  The order of preference is
 336        `GIT_EDITOR` environment, `core.editor`, `VISUAL` and
 337        `EDITOR` environment variables and then finally `vi`.
 338
 339core.pager::
 340        The command that git will use to paginate output.  Can be overridden
 341        with the `GIT_PAGER` environment variable.
 342
 343core.whitespace::
 344        A comma separated list of common whitespace problems to
 345        notice.  `git diff` will use `color.diff.whitespace` to
 346        highlight them, and `git apply --whitespace=error` will
 347        consider them as errors:
 348+
 349* `trailing-space` treats trailing whitespaces at the end of the line
 350  as an error (enabled by default).
 351* `space-before-tab` treats a space character that appears immediately
 352  before a tab character in the initial indent part of the line as an
 353  error (enabled by default).
 354* `indent-with-non-tab` treats a line that is indented with 8 or more
 355  space characters as an error (not enabled by default).
 356* `cr-at-eol` treats a carriage-return at the end of line as
 357  part of the line terminator, i.e. with it, `trailing-space`
 358  does not trigger if the character before such a carriage-return
 359  is not a whitespace (not enabled by default).
 360
 361alias.*::
 362        Command aliases for the linkgit:git[1] command wrapper - e.g.
 363        after defining "alias.last = cat-file commit HEAD", the invocation
 364        "git last" is equivalent to "git cat-file commit HEAD". To avoid
 365        confusion and troubles with script usage, aliases that
 366        hide existing git commands are ignored. Arguments are split by
 367        spaces, the usual shell quoting and escaping is supported.
 368        quote pair and a backslash can be used to quote them.
 369+
 370If the alias expansion is prefixed with an exclamation point,
 371it will be treated as a shell command.  For example, defining
 372"alias.new = !gitk --all --not ORIG_HEAD", the invocation
 373"git new" is equivalent to running the shell command
 374"gitk --all --not ORIG_HEAD".
 375
 376apply.whitespace::
 377        Tells `git-apply` how to handle whitespaces, in the same way
 378        as the '--whitespace' option. See linkgit:git-apply[1].
 379
 380branch.autosetupmerge::
 381        Tells `git-branch` and `git-checkout` to setup new branches
 382        so that linkgit:git-pull[1] will appropriately merge from the
 383        starting point branch. Note that even if this option is not set,
 384        this behavior can be chosen per-branch using the `--track`
 385        and `--no-track` options. The valid settings are: `false` -- no
 386        automatic setup is done; `true` -- automatic setup is done when the
 387        starting point is a remote branch; `always` -- automatic setup is
 388        done when the starting point is either a local branch or remote
 389        branch. This option defaults to true.
 390
 391branch.<name>.remote::
 392        When in branch <name>, it tells `git fetch` which remote to fetch.
 393        If this option is not given, `git fetch` defaults to remote "origin".
 394
 395branch.<name>.merge::
 396        When in branch <name>, it tells `git fetch` the default
 397        refspec to be marked for merging in FETCH_HEAD. The value is
 398        handled like the remote part of a refspec, and must match a
 399        ref which is fetched from the remote given by
 400        "branch.<name>.remote".
 401        The merge information is used by `git pull` (which at first calls
 402        `git fetch`) to lookup the default branch for merging. Without
 403        this option, `git pull` defaults to merge the first refspec fetched.
 404        Specify multiple values to get an octopus merge.
 405        If you wish to setup `git pull` so that it merges into <name> from
 406        another branch in the local repository, you can point
 407        branch.<name>.merge to the desired branch, and use the special setting
 408        `.` (a period) for branch.<name>.remote.
 409
 410branch.<name>.mergeoptions::
 411        Sets default options for merging into branch <name>. The syntax and
 412        supported options are equal to that of linkgit:git-merge[1], but
 413        option values containing whitespace characters are currently not
 414        supported.
 415
 416branch.<name>.rebase::
 417        When true, rebase the branch <name> on top of the fetched branch,
 418        instead of merging the default branch from the default remote.
 419        *NOTE*: this is a possibly dangerous operation; do *not* use
 420        it unless you understand the implications (see linkgit:git-rebase[1]
 421        for details).
 422
 423browser.<tool>.cmd::
 424        Specify the command to invoke the specified browser. The
 425        specified command is evaluated in shell with the URLs passed
 426        as arguments. (See linkgit:git-web--browse[1].)
 427
 428browser.<tool>.path::
 429        Override the path for the given tool that may be used to
 430        browse HTML help (see '-w' option in linkgit:git-help[1]) or a
 431        working repository in gitweb (see linkgit:git-instaweb[1]).
 432
 433clean.requireForce::
 434        A boolean to make git-clean do nothing unless given -f
 435        or -n.   Defaults to true.
 436
 437color.branch::
 438        A boolean to enable/disable color in the output of
 439        linkgit:git-branch[1]. May be set to `always`,
 440        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 441        only when the output is to a terminal. Defaults to false.
 442
 443color.branch.<slot>::
 444        Use customized color for branch coloration. `<slot>` is one of
 445        `current` (the current branch), `local` (a local branch),
 446        `remote` (a tracking branch in refs/remotes/), `plain` (other
 447        refs).
 448+
 449The value for these configuration variables is a list of colors (at most
 450two) and attributes (at most one), separated by spaces.  The colors
 451accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`,
 452`magenta`, `cyan` and `white`; the attributes are `bold`, `dim`, `ul`,
 453`blink` and `reverse`.  The first color given is the foreground; the
 454second is the background.  The position of the attribute, if any,
 455doesn't matter.
 456
 457color.diff::
 458        When set to `always`, always use colors in patch.
 459        When false (or `never`), never.  When set to `true` or `auto`, use
 460        colors only when the output is to the terminal. Defaults to false.
 461
 462color.diff.<slot>::
 463        Use customized color for diff colorization.  `<slot>` specifies
 464        which part of the patch to use the specified color, and is one
 465        of `plain` (context text), `meta` (metainformation), `frag`
 466        (hunk header), `old` (removed lines), `new` (added lines),
 467        `commit` (commit headers), or `whitespace` (highlighting
 468        whitespace errors). The values of these variables may be specified as
 469        in color.branch.<slot>.
 470
 471color.interactive::
 472        When set to `always`, always use colors for interactive prompts
 473        and displays (such as those used by "git add --interactive").
 474        When false (or `never`), never.  When set to `true` or `auto`, use
 475        colors only when the output is to the terminal. Defaults to false.
 476
 477color.interactive.<slot>::
 478        Use customized color for `git add --interactive`
 479        output. `<slot>` may be `prompt`, `header`, or `help`, for
 480        three distinct types of normal output from interactive
 481        programs.  The values of these variables may be specified as
 482        in color.branch.<slot>.
 483
 484color.pager::
 485        A boolean to enable/disable colored output when the pager is in
 486        use (default is true).
 487
 488color.status::
 489        A boolean to enable/disable color in the output of
 490        linkgit:git-status[1]. May be set to `always`,
 491        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 492        only when the output is to a terminal. Defaults to false.
 493
 494color.status.<slot>::
 495        Use customized color for status colorization. `<slot>` is
 496        one of `header` (the header text of the status message),
 497        `added` or `updated` (files which are added but not committed),
 498        `changed` (files which are changed but not added in the index),
 499        or `untracked` (files which are not tracked by git). The values of
 500        these variables may be specified as in color.branch.<slot>.
 501
 502commit.template::
 503        Specify a file to use as the template for new commit messages.
 504
 505color.ui::
 506        When set to `always`, always use colors in all git commands which
 507        are capable of colored output. When false (or `never`), never. When
 508        set to `true` or `auto`, use colors only when the output is to the
 509        terminal. When more specific variables of color.* are set, they always
 510        take precedence over this setting. Defaults to false.
 511
 512diff.autorefreshindex::
 513        When using `git diff` to compare with work tree
 514        files, do not consider stat-only change as changed.
 515        Instead, silently run `git update-index --refresh` to
 516        update the cached stat information for paths whose
 517        contents in the work tree match the contents in the
 518        index.  This option defaults to true.  Note that this
 519        affects only `git diff` Porcelain, and not lower level
 520        `diff` commands, such as `git diff-files`.
 521
 522diff.external::
 523        If this config variable is set, diff generation is not
 524        performed using the internal diff machinery, but using the
 525        given command.  Note: if you want to use an external diff
 526        program only on a subset of your files, you might want to
 527        use linkgit:gitattributes[5] instead.
 528
 529diff.renameLimit::
 530        The number of files to consider when performing the copy/rename
 531        detection; equivalent to the git diff option '-l'.
 532
 533diff.renames::
 534        Tells git to detect renames.  If set to any boolean value, it
 535        will enable basic rename detection.  If set to "copies" or
 536        "copy", it will detect copies, as well.
 537
 538fetch.unpackLimit::
 539        If the number of objects fetched over the git native
 540        transfer is below this
 541        limit, then the objects will be unpacked into loose object
 542        files. However if the number of received objects equals or
 543        exceeds this limit then the received pack will be stored as
 544        a pack, after adding any missing delta bases.  Storing the
 545        pack from a push can make the push operation complete faster,
 546        especially on slow filesystems.  If not set, the value of
 547        `transfer.unpackLimit` is used instead.
 548
 549format.numbered::
 550        A boolean which can enable sequence numbers in patch subjects.
 551        Setting this option to "auto" will enable it only if there is
 552        more than one patch.  See --numbered option in
 553        linkgit:git-format-patch[1].
 554
 555format.headers::
 556        Additional email headers to include in a patch to be submitted
 557        by mail.  See linkgit:git-format-patch[1].
 558
 559format.suffix::
 560        The default for format-patch is to output files with the suffix
 561        `.patch`. Use this variable to change that suffix (make sure to
 562        include the dot if you want it).
 563
 564format.pretty::
 565        The default pretty format for log/show/whatchanged command,
 566        See linkgit:git-log[1], linkgit:git-show[1],
 567        linkgit:git-whatchanged[1].
 568
 569gc.aggressiveWindow::
 570        The window size parameter used in the delta compression
 571        algorithm used by 'git gc --aggressive'.  This defaults
 572        to 10.
 573
 574gc.auto::
 575        When there are approximately more than this many loose
 576        objects in the repository, `git gc --auto` will pack them.
 577        Some Porcelain commands use this command to perform a
 578        light-weight garbage collection from time to time.  The
 579        default value is 6700.  Setting this to 0 disables it.
 580
 581gc.autopacklimit::
 582        When there are more than this many packs that are not
 583        marked with `*.keep` file in the repository, `git gc
 584        --auto` consolidates them into one larger pack.  The
 585        default value is 50.  Setting this to 0 disables it.
 586
 587gc.packrefs::
 588        `git gc` does not run `git pack-refs` in a bare repository by
 589        default so that older dumb-transport clients can still fetch
 590        from the repository.  Setting this to `true` lets `git
 591        gc` to run `git pack-refs`.  Setting this to `false` tells
 592        `git gc` never to run `git pack-refs`. The default setting is
 593        `notbare`. Enable it only when you know you do not have to
 594        support such clients.  The default setting will change to `true`
 595        at some stage, and setting this to `false` will continue to
 596        prevent `git pack-refs` from being run from `git gc`.
 597
 598gc.pruneexpire::
 599        When `git gc` is run, it will call `prune --expire 2.weeks.ago`.
 600        Override the grace period with this config variable.
 601
 602gc.reflogexpire::
 603        `git reflog expire` removes reflog entries older than
 604        this time; defaults to 90 days.
 605
 606gc.reflogexpireunreachable::
 607        `git reflog expire` removes reflog entries older than
 608        this time and are not reachable from the current tip;
 609        defaults to 30 days.
 610
 611gc.rerereresolved::
 612        Records of conflicted merge you resolved earlier are
 613        kept for this many days when `git rerere gc` is run.
 614        The default is 60 days.  See linkgit:git-rerere[1].
 615
 616gc.rerereunresolved::
 617        Records of conflicted merge you have not resolved are
 618        kept for this many days when `git rerere gc` is run.
 619        The default is 15 days.  See linkgit:git-rerere[1].
 620
 621rerere.enabled::
 622        Activate recording of resolved conflicts, so that identical
 623        conflict hunks can be resolved automatically, should they
 624        be encountered again.  linkgit:git-rerere[1] command is by
 625        default enabled if you create `rr-cache` directory under
 626        `$GIT_DIR`, but can be disabled by setting this option to false.
 627
 628gitcvs.enabled::
 629        Whether the CVS server interface is enabled for this repository.
 630        See linkgit:git-cvsserver[1].
 631
 632gitcvs.logfile::
 633        Path to a log file where the CVS server interface well... logs
 634        various stuff. See linkgit:git-cvsserver[1].
 635
 636gitcvs.allbinary::
 637        If true, all files are sent to the client in mode '-kb'. This
 638        causes the client to treat all files as binary files which suppresses
 639        any newline munging it otherwise might do. A work-around for the
 640        fact that there is no way yet to set single files to mode '-kb'.
 641
 642gitcvs.dbname::
 643        Database used by git-cvsserver to cache revision information
 644        derived from the git repository. The exact meaning depends on the
 645        used database driver, for SQLite (which is the default driver) this
 646        is a filename. Supports variable substitution (see
 647        linkgit:git-cvsserver[1] for details). May not contain semicolons (`;`).
 648        Default: '%Ggitcvs.%m.sqlite'
 649
 650gitcvs.dbdriver::
 651        Used Perl DBI driver. You can specify any available driver
 652        for this here, but it might not work. git-cvsserver is tested
 653        with 'DBD::SQLite', reported to work with 'DBD::Pg', and
 654        reported *not* to work with 'DBD::mysql'. Experimental feature.
 655        May not contain double colons (`:`). Default: 'SQLite'.
 656        See linkgit:git-cvsserver[1].
 657
 658gitcvs.dbuser, gitcvs.dbpass::
 659        Database user and password. Only useful if setting 'gitcvs.dbdriver',
 660        since SQLite has no concept of database users and/or passwords.
 661        'gitcvs.dbuser' supports variable substitution (see
 662        linkgit:git-cvsserver[1] for details).
 663
 664gitcvs.dbTableNamePrefix::
 665        Database table name prefix.  Prepended to the names of any
 666        database tables used, allowing a single database to be used
 667        for several repositories.  Supports variable substitution (see
 668        linkgit:git-cvsserver[1] for details).  Any non-alphabetic
 669        characters will be replaced with underscores.
 670
 671All gitcvs variables except for 'gitcvs.allbinary' can also be
 672specified as 'gitcvs.<access_method>.<varname>' (where 'access_method'
 673is one of "ext" and "pserver") to make them apply only for the given
 674access method.
 675
 676help.browser::
 677        Specify the browser that will be used to display help in the
 678        'web' format. See linkgit:git-help[1].
 679
 680help.format::
 681        Override the default help format used by linkgit:git-help[1].
 682        Values 'man', 'info', 'web' and 'html' are supported. 'man' is
 683        the default. 'web' and 'html' are the same.
 684
 685http.proxy::
 686        Override the HTTP proxy, normally configured using the 'http_proxy'
 687        environment variable (see linkgit:curl[1]).  This can be overridden
 688        on a per-remote basis; see remote.<name>.proxy
 689
 690http.sslVerify::
 691        Whether to verify the SSL certificate when fetching or pushing
 692        over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
 693        variable.
 694
 695http.sslCert::
 696        File containing the SSL certificate when fetching or pushing

 699
 700http.sslKey::
 701        File containing the SSL private key when fetching or pushing
 702        over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment
 703        variable.
 704
 705http.sslCAInfo::
 706        File containing the certificates to verify the peer with when
 707        fetching or pushing over HTTPS. Can be overridden by the
 708        'GIT_SSL_CAINFO' environment variable.
 709
 710http.sslCAPath::
 711        Path containing files with the CA certificates to verify the peer
 712        with when fetching or pushing over HTTPS. Can be overridden
 713        by the 'GIT_SSL_CAPATH' environment variable.
 714
 715http.maxRequests::
 716        How many HTTP requests to launch in parallel. Can be overridden
 717        by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5.
 718
 719http.lowSpeedLimit, http.lowSpeedTime::
 720        If the HTTP transfer speed is less than 'http.lowSpeedLimit'
 721        for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
 722        Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and
 723        'GIT_HTTP_LOW_SPEED_TIME' environment variables.
 724
 725http.noEPSV::
 726        A boolean which disables using of EPSV ftp command by curl.
 727        This can helpful with some "poor" ftp servers which don't
 728        support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
 729        environment variable. Default is false (curl will use EPSV).
 730
 731i18n.commitEncoding::
 732        Character encoding the commit messages are stored in; git itself
 733        does not care per se, but this information is necessary e.g. when
 734        importing commits from emails or in the gitk graphical history
 735        browser (and possibly at other places in the future or in other
 736        porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.
 737
 738i18n.logOutputEncoding::
 739        Character encoding the commit messages are converted to when
 740        running `git-log` and friends.
 741
 742instaweb.browser::
 743        Specify the program that will be used to browse your working
 744        repository in gitweb. See linkgit:git-instaweb[1].
 745
 746instaweb.httpd::
 747        The HTTP daemon command-line to start gitweb on your working
 748        repository. See linkgit:git-instaweb[1].
 749

 751        If true the web server started by linkgit:git-instaweb[1] will
 752        be bound to the local IP (127.0.0.1).
 753
 754instaweb.modulepath::
 755        The module path for an apache httpd used by linkgit:git-instaweb[1].
 756
 757instaweb.port::
 758        The port number to bind the gitweb httpd to. See
 759        linkgit:git-instaweb[1].
 760
 761log.showroot::
 762        If true, the initial commit will be shown as a big creation event.
 763        This is equivalent to a diff against an empty tree.
 764        Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
 765        normally hide the root commit will now show it. True by default.
 766
 767man.viewer::
 768        Specify the programs that may be used to display help in the
 769        'man' format. See linkgit:git-help[1].
 770
 771merge.summary::
 772        Whether to include summaries of merged commits in newly created
 773        merge commit messages. False by default.
 774
 775merge.tool::
 776        Controls which merge resolution program is used by
 777        linkgit:git-mergetool[1].  Valid built-in values are: "kdiff3",
 778        "tkdiff", "meld", "xxdiff", "emerge", "vimdiff", "gvimdiff", and
 779        "opendiff".  Any other value is treated is custom merge tool
 780        and there must be a corresponing mergetool.<tool>.cmd option.
 781
 782merge.verbosity::
 783        Controls the amount of output shown by the recursive merge
 784        strategy.  Level 0 outputs nothing except a final error
 785        message if conflicts were detected. Level 1 outputs only
 786        conflicts, 2 outputs conflicts and file changes.  Level 5 and
 787        above outputs debugging information.  The default is level 2.
 788        Can be overridden by 'GIT_MERGE_VERBOSITY' environment variable.
 789
 790merge.<driver>.name::
 791        Defines a human readable name for a custom low-level
 792        merge driver.  See linkgit:gitattributes[5] for details.
 793
 794merge.<driver>.driver::
 795        Defines the command that implements a custom low-level
 796        merge driver.  See linkgit:gitattributes[5] for details.
 797
 798merge.<driver>.recursive::
 799        Names a low-level merge driver to be used when
 800        performing an internal merge between common ancestors.
 801        See linkgit:gitattributes[5] for details.
 802
 803mergetool.<tool>.path::
 804        Override the path for the given tool.  This is useful in case
 805        your tool is not in the PATH.
 806
 807mergetool.<tool>.cmd::
 808        Specify the command to invoke the specified merge tool.  The
 809        specified command is evaluated in shell with the following
 810        variables available: 'BASE' is the name of a temporary file
 811        containing the common base of the files to be merged, if available;
 812        'LOCAL' is the name of a temporary file containing the contents of
 813        the file on the current branch; 'REMOTE' is the name of a temporary
 814        file containing the contents of the file from the branch being
 815        merged; 'MERGED' contains the name of the file to which the merge
 816        tool should write the results of a successful merge.
 817
 818mergetool.<tool>.trustExitCode::
 819        For a custom merge command, specify whether the exit code of
 820        the merge command can be used to determine whether the merge was
 821        successful.  If this is not set to true then the merge target file
 822        timestamp is checked and the merge assumed to have been successful
 823        if the file has been updated, otherwise the user is prompted to
 824        indicate the success of the merge.
 825
 826mergetool.keepBackup::
 827        After performing a merge, the original file with conflict markers
 828        can be saved as a file with a `.orig` extension.  If this variable
 829        is set to `false` then this file is not preserved.  Defaults to
 830        `true` (i.e. keep the backup files).
 831
 832pack.window::
 833        The size of the window used by linkgit:git-pack-objects[1] when no
 834        window size is given on the command line. Defaults to 10.
 835
 836pack.depth::
 837        The maximum delta depth used by linkgit:git-pack-objects[1] when no
 838        maximum depth is given on the command line. Defaults to 50.
 839
 840pack.windowMemory::
 841        The window memory size limit used by linkgit:git-pack-objects[1]
 842        when no limit is given on the command line.  The value can be
 843        suffixed with "k", "m", or "g".  Defaults to 0, meaning no
 844        limit.
 845
 846pack.compression::
 847        An integer -1..9, indicating the compression level for objects
 848        in a pack file. -1 is the zlib default. 0 means no
 849        compression, and 1..9 are various speed/size tradeoffs, 9 being
 850        slowest.  If not set,  defaults to core.compression.  If that is
 851        not set,  defaults to -1, the zlib default, which is "a default
 852        compromise between speed and compression (currently equivalent
 853        to level 6)."
 854
 855pack.deltaCacheSize::
 856        The maximum memory in bytes used for caching deltas in
 857        linkgit:git-pack-objects[1].
 858        A value of 0 means no limit. Defaults to 0.
 859
 860pack.deltaCacheLimit::
 861        The maximum size of a delta, that is cached in
 862        linkgit:git-pack-objects[1]. Defaults to 1000.
 863
 864pack.threads::
 865        Specifies the number of threads to spawn when searching for best
 866        delta matches.  This requires that linkgit:git-pack-objects[1]
 867        be compiled with pthreads otherwise this option is ignored with a
 868        warning. This is meant to reduce packing time on multiprocessor
 869        machines. The required amount of memory for the delta search window
 870        is however multiplied by the number of threads.
 871        Specifying 0 will cause git to auto-detect the number of CPU's
 872        and set the number of threads accordingly.
 873
 874pack.indexVersion::
 875        Specify the default pack index version.  Valid values are 1 for
 876        legacy pack index used by Git versions prior to 1.5.2, and 2 for
 877        the new pack index with capabilities for packs larger than 4 GB
 878        as well as proper protection against the repacking of corrupted
 879        packs.  Version 2 is selected and this config option ignored
 880        whenever the corresponding pack is larger than 2 GB.  Otherwise
 881        the default is 1.
 882
 883pack.packSizeLimit::
 884        The default maximum size of a pack.  This setting only affects
 885        packing to a file, i.e. the git:// protocol is unaffected.  It
 886        can be overridden by the `\--max-pack-size` option of
 887        linkgit:git-repack[1].
 888
 889pull.octopus::
 890        The default merge strategy to use when pulling multiple branches
 891        at once.
 892
 893pull.twohead::
 894        The default merge strategy to use when pulling a single branch.
 895
 896remote.<name>.url::
 897        The URL of a remote repository.  See linkgit:git-fetch[1] or
 898        linkgit:git-push[1].
 899
 900remote.<name>.proxy::
 901        For remotes that require curl (http, https and ftp), the URL to
 902        the proxy to use for that remote.  Set to the empty string to
 903        disable proxying for that remote.
 904
 905remote.<name>.fetch::
 906        The default set of "refspec" for linkgit:git-fetch[1]. See
 907        linkgit:git-fetch[1].
 908
 909remote.<name>.push::
 910        The default set of "refspec" for linkgit:git-push[1]. See
 911        linkgit:git-push[1].
 912
 913remote.<name>.skipDefaultUpdate::
 914        If true, this remote will be skipped by default when updating
 915        using the update subcommand of linkgit:git-remote[1].
 916
 917remote.<name>.receivepack::
 918        The default program to execute on the remote side when pushing.  See
 919        option \--receive-pack of linkgit:git-push[1].
 920
 921remote.<name>.uploadpack::
 922        The default program to execute on the remote side when fetching.  See
 923        option \--upload-pack of linkgit:git-fetch-pack[1].
 924
 925remote.<name>.tagopt::
 926        Setting this value to \--no-tags disables automatic tag following when
 927        fetching from remote <name>
 928
 929remotes.<group>::
 930        The list of remotes which are fetched by "git remote update
 931        <group>".  See linkgit:git-remote[1].
 932
 933repack.usedeltabaseoffset::
 934        Allow linkgit:git-repack[1] to create packs that uses
 935        delta-base offset.  Defaults to false.
 936
 937show.difftree::
 938        The default linkgit:git-diff-tree[1] arguments to be used
 939        for linkgit:git-show[1].
 940
 941showbranch.default::
 942        The default set of branches for linkgit:git-show-branch[1].
 943        See linkgit:git-show-branch[1].
 944
 945status.relativePaths::
 946        By default, linkgit:git-status[1] shows paths relative to the
 947        current directory. Setting this variable to `false` shows paths
 948        relative to the repository root (this was the default for git
 949        prior to v1.5.4).
 950
 951tar.umask::
 952        This variable can be used to restrict the permission bits of
 953        tar archive entries.  The default is 0002, which turns off the
 954        world write bit.  The special value "user" indicates that the
 955        archiving user's umask will be used instead.  See umask(2) and
 956        linkgit:git-archive[1].
 957
 958url.<base>.insteadOf::
 959        Any URL that starts with this value will be rewritten to
 960        start, instead, with <base>. In cases where some site serves a
 961        large number of repositories, and serves them with multiple
 962        access methods, and some users need to use different access
 963        methods, this feature allows people to specify any of the
 964        equivalent URLs and have git automatically rewrite the URL to
 965        the best alternative for the particular user, even for a
 966        never-before-seen repository on the site.  When more than one
 967        insteadOf strings match a given URL, the longest match is used.
 968
 969user.email::
 970        Your email address to be recorded in any newly created commits.
 971        Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and
 972        'EMAIL' environment variables.  See linkgit:git-commit-tree[1].
 973
 974user.name::
 975        Your full name to be recorded in any newly created commits.
 976        Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
 977        environment variables.  See linkgit:git-commit-tree[1].
 978
 979user.signingkey::
 980        If linkgit:git-tag[1] is not selecting the key you want it to
 981        automatically when creating a signed tag, you can override the
 982        default selection with this variable.  This option is passed
 983        unchanged to gpg's --local-user parameter, so you may specify a key
 984        using any method that gpg supports.
 985
 986whatchanged.difftree::
 987        The default linkgit:git-diff-tree[1] arguments to be used
 988        for linkgit:git-whatchanged[1].
 989
 990imap::
 991        The configuration variables in the 'imap' section are described
 992        in linkgit:git-imap-send[1].
 993
 994receive.fsckObjects::
 995        If it is set to true, git-receive-pack will check all received
 996        objects. It will abort in the case of a malformed object or a
 997        broken link. The result of an abort are only dangling objects.
 998        Defaults to false.
 999
1000receive.unpackLimit::
1001        If the number of objects received in a push is below this
1002        limit then the objects will be unpacked into loose object
1003        files. However if the number of received objects equals or
1004        exceeds this limit then the received pack will be stored as
1005        a pack, after adding any missing delta bases.  Storing the
1006        pack from a push can make the push operation complete faster,
1007        especially on slow filesystems.  If not set, the value of
1008        `transfer.unpackLimit` is used instead.
1009
1010receive.denyNonFastForwards::
1011        If set to true, git-receive-pack will deny a ref update which is
1012        not a fast forward. Use this to prevent such an update via a push,
1013        even if that push is forced. This configuration variable is
1014        set when initializing a shared repository.
1015
1016transfer.unpackLimit::
1017        When `fetch.unpackLimit` or `receive.unpackLimit` are
1018        not set, the value of this variable is used instead.
1019        The default value is 100.
1020
1021web.browser::
1022        Specify a web browser that may be used by some commands.
1023        Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
1024        may use it.
