   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.
  84

 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.symlinks::
 143        If false, symbolic links are checked out as small plain files that
 144        contain the link text. linkgit:git-update-index[1] and
 145        linkgit:git-add[1] will not change the recorded type to regular
 146        file. Useful on filesystems like FAT that do not support
 147        symbolic links. True by default.
 148
 149core.gitProxy::
 150        A "proxy command" to execute (as 'command host port') instead
 151        of establishing direct connection to the remote server when
 152        using the git protocol for fetching. If the variable value is
 153        in the "COMMAND for DOMAIN" format, the command is applied only
 154        on hostnames ending with the specified domain string. This variable
 155        may be set multiple times and is matched in the given order;
 156        the first match wins.
 157+
 158Can be overridden by the 'GIT_PROXY_COMMAND' environment variable
 159(which always applies universally, without the special "for"
 160handling).
 161
 162core.ignoreStat::
 163        The working copy files are assumed to stay unchanged until you
 164        mark them otherwise manually - Git will not detect the file changes
 165        by lstat() calls. This is useful on systems where those are very
 166        slow, such as Microsoft Windows.  See linkgit:git-update-index[1].
 167        False by default.
 168
 169core.preferSymlinkRefs::
 170        Instead of the default "symref" format for HEAD
 171        and other symbolic reference files, use symbolic links.
 172        This is sometimes needed to work with old scripts that
 173        expect HEAD to be a symbolic link.
 174
 175core.bare::
 176        If true this repository is assumed to be 'bare' and has no
 177        working directory associated with it.  If this is the case a
 178        number of commands that require a working directory will be
 179        disabled, such as linkgit:git-add[1] or linkgit:git-merge[1].
 180+
 181This setting is automatically guessed by linkgit:git-clone[1] or
 182linkgit:git-init[1] when the repository was created.  By default a
 183repository that ends in "/.git" is assumed to be not bare (bare =
 184false), while all other repositories are assumed to be bare (bare
 185= true).
 186
 187core.worktree::
 188        Set the path to the working tree.  The value will not be
 189        used in combination with repositories found automatically in
 190        a .git directory (i.e. $GIT_DIR is not set).
 191        This can be overridden by the GIT_WORK_TREE environment
 192        variable and the '--work-tree' command line option.
 193
 194core.logAllRefUpdates::
 195        Enable the reflog. Updates to a ref <ref> is logged to the file
 196        "$GIT_DIR/logs/<ref>", by appending the new and old
 197        SHA1, the date/time and the reason of the update, but
 198        only when the file exists.  If this configuration
 199        variable is set to true, missing "$GIT_DIR/logs/<ref>"
 200        file is automatically created for branch heads.
 201+
 202This information can be used to determine what commit
 203was the tip of a branch "2 days ago".
 204+
 205This value is true by default in a repository that has
 206a working directory associated with it, and false by
 207default in a bare repository.
 208
 209core.repositoryFormatVersion::
 210        Internal variable identifying the repository format and layout
 211        version.
 212
 213core.sharedRepository::
 214        When 'group' (or 'true'), the repository is made shareable between
 215        several users in a group (making sure all the files and objects are
 216        group-writable). When 'all' (or 'world' or 'everybody'), the
 217        repository will be readable by all users, additionally to being
 218        group-shareable. When 'umask' (or 'false'), git will use permissions
 219        reported by umask(2). See linkgit:git-init[1]. False by default.
 220
 221core.warnAmbiguousRefs::
 222        If true, git will warn you if the ref name you passed it is ambiguous
 223        and might match multiple refs in the .git/refs/ tree. True by default.
 224
 225core.compression::
 226        An integer -1..9, indicating a default compression level.
 227        -1 is the zlib default. 0 means no compression,
 228        and 1..9 are various speed/size tradeoffs, 9 being slowest.
 229        If set, this provides a default to other compression variables,
 230        such as 'core.loosecompression' and 'pack.compression'.
 231
 232core.loosecompression::
 233        An integer -1..9, indicating the compression level for objects that
 234        are not in a pack file. -1 is the zlib default. 0 means no
 235        compression, and 1..9 are various speed/size tradeoffs, 9 being
 236        slowest.  If not set,  defaults to core.compression.  If that is
 237        not set,  defaults to 1 (best speed).
 238
 239core.packedGitWindowSize::
 240        Number of bytes of a pack file to map into memory in a
 241        single mapping operation.  Larger window sizes may allow
 242        your system to process a smaller number of large pack files
 243        more quickly.  Smaller window sizes will negatively affect
 244        performance due to increased calls to the operating system's
 245        memory manager, but may improve performance when accessing
 246        a large number of large pack files.
 247+
 248Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
 249MiB on 32 bit platforms and 1 GiB on 64 bit platforms.  This should
 250be reasonable for all users/operating systems.  You probably do
 251not need to adjust this value.
 252+
 253Common unit suffixes of 'k', 'm', or 'g' are supported.
 254
 255core.packedGitLimit::
 256        Maximum number of bytes to map simultaneously into memory
 257        from pack files.  If Git needs to access more than this many
 258        bytes at once to complete an operation it will unmap existing
 259        regions to reclaim virtual address space within the process.
 260+
 261Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms.
 262This should be reasonable for all users/operating systems, except on
 263the largest projects.  You probably do not need to adjust this value.
 264+
 265Common unit suffixes of 'k', 'm', or 'g' are supported.
 266
 267core.deltaBaseCacheLimit::
 268        Maximum number of bytes to reserve for caching base objects
 269        that multiple deltafied objects reference.  By storing the
 270        entire decompressed base objects in a cache Git is able
 271        to avoid unpacking and decompressing frequently used base
 272        objects multiple times.
 273+
 274Default is 16 MiB on all platforms.  This should be reasonable
 275for all users/operating systems, except on the largest projects.
 276You probably do not need to adjust this value.
 277+
 278Common unit suffixes of 'k', 'm', or 'g' are supported.
 279
 280core.excludesfile::
 281        In addition to '.gitignore' (per-directory) and
 282        '.git/info/exclude', git looks into this file for patterns
 283        of files which are not meant to be tracked.  See
 284        linkgit:gitignore[5].
 285
 286core.editor::
 287        Commands such as `commit` and `tag` that lets you edit
 288        messages by launching an editor uses the value of this
 289        variable when it is set, and the environment variable
 290        `GIT_EDITOR` is not set.  The order of preference is
 291        `GIT_EDITOR` environment, `core.editor`, `VISUAL` and
 292        `EDITOR` environment variables and then finally `vi`.
 293
 294core.pager::
 295        The command that git will use to paginate output.  Can be overridden
 296        with the `GIT_PAGER` environment variable.
 297
 298core.whitespace::
 299        A comma separated list of common whitespace problems to
 300        notice.  `git diff` will use `color.diff.whitespace` to
 301        highlight them, and `git apply --whitespace=error` will
 302        consider them as errors:
 303+
 304* `trailing-space` treats trailing whitespaces at the end of the line
 305  as an error (enabled by default).
 306* `space-before-tab` treats a space character that appears immediately
 307  before a tab character in the initial indent part of the line as an
 308  error (enabled by default).
 309* `indent-with-non-tab` treats a line that is indented with 8 or more
 310  space characters as an error (not enabled by default).
 311
 312alias.*::
 313        Command aliases for the linkgit:git[1] command wrapper - e.g.
 314        after defining "alias.last = cat-file commit HEAD", the invocation
 315        "git last" is equivalent to "git cat-file commit HEAD". To avoid
 316        confusion and troubles with script usage, aliases that
 317        hide existing git commands are ignored. Arguments are split by
 318        spaces, the usual shell quoting and escaping is supported.
 319        quote pair and a backslash can be used to quote them.
 320+
 321If the alias expansion is prefixed with an exclamation point,
 322it will be treated as a shell command.  For example, defining
 323"alias.new = !gitk --all --not ORIG_HEAD", the invocation
 324"git new" is equivalent to running the shell command
 325"gitk --all --not ORIG_HEAD".
 326
 327apply.whitespace::
 328        Tells `git-apply` how to handle whitespaces, in the same way
 329        as the '--whitespace' option. See linkgit:git-apply[1].
 330
 331branch.autosetupmerge::
 332        Tells `git-branch` and `git-checkout` to setup new branches
 333        so that linkgit:git-pull[1] will appropriately merge from that
 334        remote branch.  Note that even if this option is not set,
 335        this behavior can be chosen per-branch using the `--track`
 336        and `--no-track` options.  This option defaults to false.
 337
 338branch.<name>.remote::
 339        When in branch <name>, it tells `git fetch` which remote to fetch.
 340        If this option is not given, `git fetch` defaults to remote "origin".
 341
 342branch.<name>.merge::
 343        When in branch <name>, it tells `git fetch` the default
 344        refspec to be marked for merging in FETCH_HEAD. The value is
 345        handled like the remote part of a refspec, and must match a
 346        ref which is fetched from the remote given by
 347        "branch.<name>.remote".
 348        The merge information is used by `git pull` (which at first calls
 349        `git fetch`) to lookup the default branch for merging. Without
 350        this option, `git pull` defaults to merge the first refspec fetched.
 351        Specify multiple values to get an octopus merge.
 352        If you wish to setup `git pull` so that it merges into <name> from
 353        another branch in the local repository, you can point
 354        branch.<name>.merge to the desired branch, and use the special setting
 355        `.` (a period) for branch.<name>.remote.
 356
 357branch.<name>.mergeoptions::
 358        Sets default options for merging into branch <name>. The syntax and
 359        supported options are equal to that of linkgit:git-merge[1], but
 360        option values containing whitespace characters are currently not
 361        supported.
 362
 363branch.<name>.rebase::
 364        When true, rebase the branch <name> on top of the fetched branch,
 365        instead of merging the default branch from the default remote.
 366        *NOTE*: this is a possibly dangerous operation; do *not* use
 367        it unless you understand the implications (see linkgit:git-rebase[1]
 368        for details).
 369
 370clean.requireForce::
 371        A boolean to make git-clean do nothing unless given -f
 372        or -n.   Defaults to true.
 373
 374color.branch::
 375        A boolean to enable/disable color in the output of
 376        linkgit:git-branch[1]. May be set to `always`,
 377        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 378        only when the output is to a terminal. Defaults to false.
 379
 380color.branch.<slot>::
 381        Use customized color for branch coloration. `<slot>` is one of
 382        `current` (the current branch), `local` (a local branch),
 383        `remote` (a tracking branch in refs/remotes/), `plain` (other
 384        refs).
 385+
 386The value for these configuration variables is a list of colors (at most
 387two) and attributes (at most one), separated by spaces.  The colors
 388accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`,
 389`magenta`, `cyan` and `white`; the attributes are `bold`, `dim`, `ul`,
 390`blink` and `reverse`.  The first color given is the foreground; the
 391second is the background.  The position of the attribute, if any,
 392doesn't matter.
 393
 394color.diff::
 395        When set to `always`, always use colors in patch.
 396        When false (or `never`), never.  When set to `true` or `auto`, use
 397        colors only when the output is to the terminal. Defaults to false.
 398
 399color.diff.<slot>::
 400        Use customized color for diff colorization.  `<slot>` specifies
 401        which part of the patch to use the specified color, and is one
 402        of `plain` (context text), `meta` (metainformation), `frag`
 403        (hunk header), `old` (removed lines), `new` (added lines),
 404        `commit` (commit headers), or `whitespace` (highlighting
 405        whitespace errors). The values of these variables may be specified as
 406        in color.branch.<slot>.
 407
 408color.interactive::
 409        When set to `always`, always use colors for interactive prompts
 410        and displays (such as those used by "git add --interactive").
 411        When false (or `never`), never.  When set to `true` or `auto`, use
 412        colors only when the output is to the terminal. Defaults to false.
 413
 414color.interactive.<slot>::
 415        Use customized color for `git add --interactive`
 416        output. `<slot>` may be `prompt`, `header`, or `help`, for
 417        three distinct types of normal output from interactive
 418        programs.  The values of these variables may be specified as
 419        in color.branch.<slot>.
 420
 421color.pager::
 422        A boolean to enable/disable colored output when the pager is in
 423        use (default is true).
 424
 425color.status::
 426        A boolean to enable/disable color in the output of
 427        linkgit:git-status[1]. May be set to `always`,
 428        `false` (or `never`) or `auto` (or `true`), in which case colors are used
 429        only when the output is to a terminal. Defaults to false.
 430
 431color.status.<slot>::
 432        Use customized color for status colorization. `<slot>` is
 433        one of `header` (the header text of the status message),
 434        `added` or `updated` (files which are added but not committed),
 435        `changed` (files which are changed but not added in the index),
 436        or `untracked` (files which are not tracked by git). The values of
 437        these variables may be specified as in color.branch.<slot>.
 438
 439commit.template::
 440        Specify a file to use as the template for new commit messages.
 441
 442diff.autorefreshindex::
 443        When using `git diff` to compare with work tree
 444        files, do not consider stat-only change as changed.
 445        Instead, silently run `git update-index --refresh` to
 446        update the cached stat information for paths whose
 447        contents in the work tree match the contents in the
 448        index.  This option defaults to true.  Note that this
 449        affects only `git diff` Porcelain, and not lower level
 450        `diff` commands, such as `git diff-files`.
 451
 452diff.external::
 453        If this config variable is set, diff generation is not
 454        performed using the internal diff machinery, but using the
 455        given command.  Note: if you want to use an external diff
 456        program only on a subset of your files, you might want to
 457        use linkgit:gitattributes[5] instead.
 458
 459diff.renameLimit::
 460        The number of files to consider when performing the copy/rename
 461        detection; equivalent to the git diff option '-l'.
 462
 463diff.renames::
 464        Tells git to detect renames.  If set to any boolean value, it
 465        will enable basic rename detection.  If set to "copies" or
 466        "copy", it will detect copies, as well.
 467
 468fetch.unpackLimit::
 469        If the number of objects fetched over the git native
 470        transfer is below this
 471        limit, then the objects will be unpacked into loose object
 472        files. However if the number of received objects equals or
 473        exceeds this limit then the received pack will be stored as
 474        a pack, after adding any missing delta bases.  Storing the
 475        pack from a push can make the push operation complete faster,
 476        especially on slow filesystems.
 477
 478format.numbered::
 479        A boolean which can enable sequence numbers in patch subjects.
 480        Setting this option to "auto" will enable it only if there is
 481        more than one patch.  See --numbered option in
 482        linkgit:git-format-patch[1].
 483
 484format.headers::
 485        Additional email headers to include in a patch to be submitted
 486        by mail.  See linkgit:git-format-patch[1].
 487
 488format.suffix::
 489        The default for format-patch is to output files with the suffix
 490        `.patch`. Use this variable to change that suffix (make sure to
 491        include the dot if you want it).
 492
 493gc.aggressiveWindow::
 494        The window size parameter used in the delta compression
 495        algorithm used by 'git gc --aggressive'.  This defaults
 496        to 10.
 497
 498gc.auto::
 499        When there are approximately more than this many loose
 500        objects in the repository, `git gc --auto` will pack them.
 501        Some Porcelain commands use this command to perform a
 502        light-weight garbage collection from time to time.  Setting
 503        this to 0 disables it.
 504
 505gc.autopacklimit::
 506        When there are more than this many packs that are not
 507        marked with `*.keep` file in the repository, `git gc
 508        --auto` consolidates them into one larger pack.  Setting
 509        this to 0 disables this.
 510
 511gc.packrefs::
 512        `git gc` does not run `git pack-refs` in a bare repository by
 513        default so that older dumb-transport clients can still fetch
 514        from the repository.  Setting this to `true` lets `git
 515        gc` to run `git pack-refs`.  Setting this to `false` tells
 516        `git gc` never to run `git pack-refs`. The default setting is
 517        `notbare`. Enable it only when you know you do not have to
 518        support such clients.  The default setting will change to `true`
 519        at some stage, and setting this to `false` will continue to
 520        prevent `git pack-refs` from being run from `git gc`.
 521
 522gc.reflogexpire::
 523        `git reflog expire` removes reflog entries older than
 524        this time; defaults to 90 days.
 525
 526gc.reflogexpireunreachable::
 527        `git reflog expire` removes reflog entries older than
 528        this time and are not reachable from the current tip;
 529        defaults to 30 days.
 530
 531gc.rerereresolved::
 532        Records of conflicted merge you resolved earlier are
 533        kept for this many days when `git rerere gc` is run.
 534        The default is 60 days.  See linkgit:git-rerere[1].
 535
 536gc.rerereunresolved::
 537        Records of conflicted merge you have not resolved are
 538        kept for this many days when `git rerere gc` is run.
 539        The default is 15 days.  See linkgit:git-rerere[1].
 540
 541rerere.enabled::
 542        Activate recording of resolved conflicts, so that identical
 543        conflict hunks can be resolved automatically, should they
 544        be encountered again.  linkgit:git-rerere[1] command is by
 545        default enabled, but can be disabled by setting this option to
 546        false.
 547
 548gitcvs.enabled::
 549        Whether the CVS server interface is enabled for this repository.
 550        See linkgit:git-cvsserver[1].
 551
 552gitcvs.logfile::
 553        Path to a log file where the CVS server interface well... logs
 554        various stuff. See linkgit:git-cvsserver[1].
 555
 556gitcvs.allbinary::
 557        If true, all files are sent to the client in mode '-kb'. This
 558        causes the client to treat all files as binary files which suppresses
 559        any newline munging it otherwise might do. A work-around for the
 560        fact that there is no way yet to set single files to mode '-kb'.
 561
 562gitcvs.dbname::
 563        Database used by git-cvsserver to cache revision information
 564        derived from the git repository. The exact meaning depends on the
 565        used database driver, for SQLite (which is the default driver) this
 566        is a filename. Supports variable substitution (see
 567        linkgit:git-cvsserver[1] for details). May not contain semicolons (`;`).
 568        Default: '%Ggitcvs.%m.sqlite'
 569
 570gitcvs.dbdriver::
 571        Used Perl DBI driver. You can specify any available driver
 572        for this here, but it might not work. git-cvsserver is tested
 573        with 'DBD::SQLite', reported to work with 'DBD::Pg', and
 574        reported *not* to work with 'DBD::mysql'. Experimental feature.
 575        May not contain double colons (`:`). Default: 'SQLite'.
 576        See linkgit:git-cvsserver[1].
 577
 578gitcvs.dbuser, gitcvs.dbpass::
 579        Database user and password. Only useful if setting 'gitcvs.dbdriver',
 580        since SQLite has no concept of database users and/or passwords.
 581        'gitcvs.dbuser' supports variable substitution (see
 582        linkgit:git-cvsserver[1] for details).
 583
 584All gitcvs variables except for 'gitcvs.allbinary' can also be
 585specified as 'gitcvs.<access_method>.<varname>' (where 'access_method'
 586is one of "ext" and "pserver") to make them apply only for the given
 587access method.
 588
 589help.browser::
 590        Specify the browser that will be used to display help in the
 591        'web' format. See linkgit:git-help[1].
 592
 593help.format::
 594        Override the default help format used by linkgit:git-help[1].
 595        Values 'man', 'info', 'web' and 'html' are supported. 'man' is
 596        the default. 'web' and 'html' are the same.
 597
 598http.proxy::
 599        Override the HTTP proxy, normally configured using the 'http_proxy'
 600        environment variable (see linkgit:curl[1]).  This can be overridden
 601        on a per-remote basis; see remote.<name>.proxy
 602
 603http.sslVerify::
 604        Whether to verify the SSL certificate when fetching or pushing
 605        over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
 606        variable.
 607
 608http.sslCert::
 609        File containing the SSL certificate when fetching or pushing
 610        over HTTPS. Can be overridden by the 'GIT_SSL_CERT' environment
 611        variable.
 612
 613http.sslKey::
 614        File containing the SSL private key when fetching or pushing
 615        over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment
 616        variable.
 617
 618http.sslCAInfo::
 619        File containing the certificates to verify the peer with when
 620        fetching or pushing over HTTPS. Can be overridden by the
 621        'GIT_SSL_CAINFO' environment variable.
 622
 623http.sslCAPath::
 624        Path containing files with the CA certificates to verify the peer
 625        with when fetching or pushing over HTTPS. Can be overridden
 626        by the 'GIT_SSL_CAPATH' environment variable.
 627
 628http.maxRequests::
 629        How many HTTP requests to launch in parallel. Can be overridden
 630        by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5.
 631
 632http.lowSpeedLimit, http.lowSpeedTime::
 633        If the HTTP transfer speed is less than 'http.lowSpeedLimit'
 634        for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
 635        Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and
 636        'GIT_HTTP_LOW_SPEED_TIME' environment variables.
 637
 638http.noEPSV::
 639        A boolean which disables using of EPSV ftp command by curl.
 640        This can helpful with some "poor" ftp servers which don't
 641        support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
 642        environment variable. Default is false (curl will use EPSV).
 643
 644i18n.commitEncoding::
 645        Character encoding the commit messages are stored in; git itself
 646        does not care per se, but this information is necessary e.g. when
 647        importing commits from emails or in the gitk graphical history
 648        browser (and possibly at other places in the future or in other
 649        porcelains). See e.g. linkgit:git-mailinfo[1]. Defaults to 'utf-8'.
 650
 651i18n.logOutputEncoding::
 652        Character encoding the commit messages are converted to when
 653        running `git-log` and friends.
 654
 655instaweb.browser::
 656        Specify the program that will be used to browse your working
 657        repository in gitweb. See linkgit:git-instaweb[1].
 658
 659instaweb.httpd::
 660        The HTTP daemon command-line to start gitweb on your working
 661        repository. See linkgit:git-instaweb[1].
 662
 663instaweb.local::
 664        If true the web server started by linkgit:git-instaweb[1] will
 665        be bound to the local IP (127.0.0.1).
 666
 667instaweb.modulepath::
 668        The module path for an apache httpd used by linkgit:git-instaweb[1].
 669
 670instaweb.port::
 671        The port number to bind the gitweb httpd to. See
 672        linkgit:git-instaweb[1].
 673
 674log.showroot::
 675        If true, the initial commit will be shown as a big creation event.
 676        This is equivalent to a diff against an empty tree.
 677        Tools like linkgit:git-log[1] or linkgit:git-whatchanged[1], which
 678        normally hide the root commit will now show it. True by default.
 679
 680merge.summary::
 681        Whether to include summaries of merged commits in newly created
 682        merge commit messages. False by default.
 683
 684merge.tool::
 685        Controls which merge resolution program is used by
 686        linkgit:git-mergetool[1].  Valid values are: "kdiff3", "tkdiff",
 687        "meld", "xxdiff", "emerge", "vimdiff", "gvimdiff", and "opendiff".
 688
 689merge.verbosity::
 690        Controls the amount of output shown by the recursive merge
 691        strategy.  Level 0 outputs nothing except a final error
 692        message if conflicts were detected. Level 1 outputs only
 693        conflicts, 2 outputs conflicts and file changes.  Level 5 and
 694        above outputs debugging information.  The default is level 2.
 695        Can be overridden by 'GIT_MERGE_VERBOSITY' environment variable.
 696
 697merge.<driver>.name::
 698        Defines a human readable name for a custom low-level
 699        merge driver.  See linkgit:gitattributes[5] for details.
 700
 701merge.<driver>.driver::
 702        Defines the command that implements a custom low-level
 703        merge driver.  See linkgit:gitattributes[5] for details.
 704
 705merge.<driver>.recursive::
 706        Names a low-level merge driver to be used when
 707        performing an internal merge between common ancestors.
 708        See linkgit:gitattributes[5] for details.
 709
 710mergetool.<tool>.path::
 711        Override the path for the given tool.  This is useful in case
 712        your tool is not in the PATH.
 713
 714pack.window::
 715        The size of the window used by linkgit:git-pack-objects[1] when no
 716        window size is given on the command line. Defaults to 10.
 717
 718pack.depth::
 719        The maximum delta depth used by linkgit:git-pack-objects[1] when no
 720        maximum depth is given on the command line. Defaults to 50.
 721
 722pack.windowMemory::
 723        The window memory size limit used by linkgit:git-pack-objects[1]
 724        when no limit is given on the command line.  The value can be
 725        suffixed with "k", "m", or "g".  Defaults to 0, meaning no
 726        limit.
 727
 728pack.compression::
 729        An integer -1..9, indicating the compression level for objects
 730        in a pack file. -1 is the zlib default. 0 means no
 731        compression, and 1..9 are various speed/size tradeoffs, 9 being
 732        slowest.  If not set,  defaults to core.compression.  If that is
 733        not set,  defaults to -1, the zlib default, which is "a default
 734        compromise between speed and compression (currently equivalent
 735        to level 6)."
 736
 737pack.deltaCacheSize::
 738        The maximum memory in bytes used for caching deltas in
 739        linkgit:git-pack-objects[1].
 740        A value of 0 means no limit. Defaults to 0.
 741
 742pack.deltaCacheLimit::
 743        The maximum size of a delta, that is cached in
 744        linkgit:git-pack-objects[1]. Defaults to 1000.
 745
 746pack.threads::
 747        Specifies the number of threads to spawn when searching for best
 748        delta matches.  This requires that linkgit:git-pack-objects[1]
 749        be compiled with pthreads otherwise this option is ignored with a
 750        warning. This is meant to reduce packing time on multiprocessor
 751        machines. The required amount of memory for the delta search window
 752        is however multiplied by the number of threads.
 753
 754pack.indexVersion::
 755        Specify the default pack index version.  Valid values are 1 for
 756        legacy pack index used by Git versions prior to 1.5.2, and 2 for
 757        the new pack index with capabilities for packs larger than 4 GB
 758        as well as proper protection against the repacking of corrupted
 759        packs.  Version 2 is selected and this config option ignored
 760        whenever the corresponding pack is larger than 2 GB.  Otherwise
 761        the default is 1.
 762
 763pull.octopus::
 764        The default merge strategy to use when pulling multiple branches
 765        at once.
 766
 767pull.twohead::
 768        The default merge strategy to use when pulling a single branch.
 769
 770remote.<name>.url::
 771        The URL of a remote repository.  See linkgit:git-fetch[1] or
 772        linkgit:git-push[1].
 773
 774remote.<name>.proxy::
 775        For remotes that require curl (http, https and ftp), the URL to
 776        the proxy to use for that remote.  Set to the empty string to
 777        disable proxying for that remote.
 778
 779remote.<name>.fetch::
 780        The default set of "refspec" for linkgit:git-fetch[1]. See
 781        linkgit:git-fetch[1].
 782
 783remote.<name>.push::
 784        The default set of "refspec" for linkgit:git-push[1]. See
 785        linkgit:git-push[1].
 786
 787remote.<name>.skipDefaultUpdate::
 788        If true, this remote will be skipped by default when updating
 789        using the update subcommand of linkgit:git-remote[1].
 790
 791remote.<name>.receivepack::
 792        The default program to execute on the remote side when pushing.  See
 793        option \--exec of linkgit:git-push[1].
 794
 795remote.<name>.uploadpack::
 796        The default program to execute on the remote side when fetching.  See
 797        option \--exec of linkgit:git-fetch-pack[1].
 798
 799remote.<name>.tagopt::
 800        Setting this value to --no-tags disables automatic tag following when fetching
 801        from remote <name>
 802
 803remotes.<group>::
 804        The list of remotes which are fetched by "git remote update
 805        <group>".  See linkgit:git-remote[1].
 806
 807repack.usedeltabaseoffset::
 808        Allow linkgit:git-repack[1] to create packs that uses
 809        delta-base offset.  Defaults to false.
 810
 811show.difftree::
 812        The default linkgit:git-diff-tree[1] arguments to be used
 813        for linkgit:git-show[1].
 814

 816        The default set of branches for linkgit:git-show-branch[1].
 817        See linkgit:git-show-branch[1].
 818
 819status.relativePaths::
 820        By default, linkgit:git-status[1] shows paths relative to the
 821        current directory. Setting this variable to `false` shows paths
 822        relative to the repository root (this was the default for git
 823        prior to v1.5.4).
 824
 825tar.umask::
 826        This variable can be used to restrict the permission bits of
 827        tar archive entries.  The default is 0002, which turns off the
 828        world write bit.  The special value "user" indicates that the
 829        archiving user's umask will be used instead.  See umask(2) and
 830        linkgit:git-archive[1].
 831
 832user.email::
 833        Your email address to be recorded in any newly created commits.
 834        Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and
 835        'EMAIL' environment variables.  See linkgit:git-commit-tree[1].
 836
 837user.name::
 838        Your full name to be recorded in any newly created commits.
 839        Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
 840        environment variables.  See linkgit:git-commit-tree[1].
 841
 842user.signingkey::
 843        If linkgit:git-tag[1] is not selecting the key you want it to
 844        automatically when creating a signed tag, you can override the
 845        default selection with this variable.  This option is passed
 846        unchanged to gpg's --local-user parameter, so you may specify a key
 847        using any method that gpg supports.
 848
 849whatchanged.difftree::
 850        The default linkgit:git-diff-tree[1] arguments to be used
 851        for linkgit:git-whatchanged[1].
 852
 853imap::
 854        The configuration variables in the 'imap' section are described
 855        in linkgit:git-imap-send[1].
 856
 857receive.unpackLimit::
 858        If the number of objects received in a push is below this
 859        limit then the objects will be unpacked into loose object
 860        files. However if the number of received objects equals or
 861        exceeds this limit then the received pack will be stored as
 862        a pack, after adding any missing delta bases.  Storing the
 863        pack from a push can make the push operation complete faster,
 864        especially on slow filesystems.
 865
 866receive.denyNonFastForwards::
 867        If set to true, git-receive-pack will deny a ref update which is
 868        not a fast forward. Use this to prevent such an update via a push,
 869        even if that push is forced. This configuration variable is
 870        set when initializing a shared repository.
 871
 872transfer.unpackLimit::
 873        When `fetch.unpackLimit` or `receive.unpackLimit` are
 874        not set, the value of this variable is used instead.
 875
 876web.browser::
 877        Specify a web browser that may be used by some commands.
 878        Currently only linkgit:git-instaweb[1] and linkgit:git-help[1]
 879        may use it.
