   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 gitlink: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. gitlink:git-update-index[1] and
 145        gitlink: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 gitlink: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 gitlink:git-add[1] or gitlink:git-merge[1].
 180+
 181This setting is automatically guessed by gitlink:git-clone[1] or
 182gitlink: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 gitlink: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
 230core.loosecompression::
 231        An integer -1..9, indicating the compression level for objects that
 232        are not in a pack file. -1 is the zlib default. 0 means no
 233        compression, and 1..9 are various speed/size tradeoffs, 9 being
 234        slowest.  If not set,  defaults to core.compression.  If that is
 235        not set,  defaults to 0 (best speed).
 236
 237core.packedGitWindowSize::
 238        Number of bytes of a pack file to map into memory in a
 239        single mapping operation.  Larger window sizes may allow
 240        your system to process a smaller number of large pack files
 241        more quickly.  Smaller window sizes will negatively affect
 242        performance due to increased calls to the operating system's
 243        memory manager, but may improve performance when accessing
 244        a large number of large pack files.
 245+
 246Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
 247MiB on 32 bit platforms and 1 GiB on 64 bit platforms.  This should
 248be reasonable for all users/operating systems.  You probably do
 249not need to adjust this value.
 250+
 251Common unit suffixes of 'k', 'm', or 'g' are supported.
 252
 253core.packedGitLimit::
 254        Maximum number of bytes to map simultaneously into memory
 255        from pack files.  If Git needs to access more than this many
 256        bytes at once to complete an operation it will unmap existing
 257        regions to reclaim virtual address space within the process.
 258+
 259Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms.
 260This should be reasonable for all users/operating systems, except on
 261the largest projects.  You probably do not need to adjust this value.
 262+
 263Common unit suffixes of 'k', 'm', or 'g' are supported.
 264
 265core.deltaBaseCacheLimit::
 266        Maximum number of bytes to reserve for caching base objects
 267        that multiple deltafied objects reference.  By storing the
 268        entire decompressed base objects in a cache Git is able
 269        to avoid unpacking and decompressing frequently used base
 270        objects multiple times.
 271+
 272Default is 16 MiB on all platforms.  This should be reasonable
 273for all users/operating systems, except on the largest projects.
 274You probably do not need to adjust this value.
 275+
 276Common unit suffixes of 'k', 'm', or 'g' are supported.
 277
 278core.excludesfile::
 279        In addition to '.gitignore' (per-directory) and
 280        '.git/info/exclude', git looks into this file for patterns
 281        of files which are not meant to be tracked.  See
 282        gitlink:gitignore[5].
 283
 284core.editor::
 285        Commands such as `commit` and `tag` that lets you edit
 286        messages by launching an editor uses the value of this
 287        variable when it is set, and the environment variable
 288        `GIT_EDITOR` is not set.  The order of preference is
 289        `GIT_EDITOR` environment, `core.editor`, `VISUAL` and
 290        `EDITOR` environment variables and then finally `vi`.
 291
 292core.pager::
 293        The command that git will use to paginate output.  Can be overridden
 294        with the `GIT_PAGER` environment variable.
 295
 296alias.*::
 297        Command aliases for the gitlink:git[1] command wrapper - e.g.
 298        after defining "alias.last = cat-file commit HEAD", the invocation
 299        "git last" is equivalent to "git cat-file commit HEAD". To avoid
 300        confusion and troubles with script usage, aliases that
 301        hide existing git commands are ignored. Arguments are split by
 302        spaces, the usual shell quoting and escaping is supported.
 303        quote pair and a backslash can be used to quote them.
 304+
 305If the alias expansion is prefixed with an exclamation point,
 306it will be treated as a shell command.  For example, defining
 307"alias.new = !gitk --all --not ORIG_HEAD", the invocation
 308"git new" is equivalent to running the shell command
 309"gitk --all --not ORIG_HEAD".
 310
 311apply.whitespace::
 312        Tells `git-apply` how to handle whitespaces, in the same way
 313        as the '--whitespace' option. See gitlink:git-apply[1].
 314
 315branch.autosetupmerge::
 316        Tells `git-branch` and `git-checkout` to setup new branches
 317        so that gitlink:git-pull[1] will appropriately merge from that
 318        remote branch.  Note that even if this option is not set,
 319        this behavior can be chosen per-branch using the `--track`
 320        and `--no-track` options.  This option defaults to false.
 321
 322branch.<name>.remote::
 323        When in branch <name>, it tells `git fetch` which remote to fetch.
 324        If this option is not given, `git fetch` defaults to remote "origin".
 325
 326branch.<name>.merge::
 327        When in branch <name>, it tells `git fetch` the default
 328        refspec to be marked for merging in FETCH_HEAD. The value is
 329        handled like the remote part of a refspec, and must match a
 330        ref which is fetched from the remote given by
 331        "branch.<name>.remote".
 332        The merge information is used by `git pull` (which at first calls
 333        `git fetch`) to lookup the default branch for merging. Without
 334        this option, `git pull` defaults to merge the first refspec fetched.
 335        Specify multiple values to get an octopus merge.
 336        If you wish to setup `git pull` so that it merges into <name> from
 337        another branch in the local repository, you can point
 338        branch.<name>.merge to the desired branch, and use the special setting
 339        `.` (a period) for branch.<name>.remote.
 340
 341branch.<name>.mergeoptions::
 342        Sets default options for merging into branch <name>. The syntax and
 343        supported options are equal to that of gitlink:git-merge[1], but
 344        option values containing whitespace characters are currently not
 345        supported.
 346
 347clean.requireForce::
 348        A boolean to make git-clean do nothing unless given -f
 349        or -n.   Defaults to true.
 350
 351color.branch::
 352        A boolean to enable/disable color in the output of
 353        gitlink:git-branch[1]. May be set to `true` (or `always`),
 354        `false` (or `never`) or `auto`, in which case colors are used
 355        only when the output is to a terminal. Defaults to false.
 356
 357color.branch.<slot>::
 358        Use customized color for branch coloration. `<slot>` is one of
 359        `current` (the current branch), `local` (a local branch),
 360        `remote` (a tracking branch in refs/remotes/), `plain` (other
 361        refs).
 362+
 363The value for these configuration variables is a list of colors (at most
 364two) and attributes (at most one), separated by spaces.  The colors
 365accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`,
 366`magenta`, `cyan` and `white`; the attributes are `bold`, `dim`, `ul`,
 367`blink` and `reverse`.  The first color given is the foreground; the
 368second is the background.  The position of the attribute, if any,
 369doesn't matter.
 370
 371color.diff::
 372        When true (or `always`), always use colors in patch.
 373        When false (or `never`), never.  When set to `auto`, use
 374        colors only when the output is to the terminal.
 375
 376color.diff.<slot>::
 377        Use customized color for diff colorization.  `<slot>` specifies
 378        which part of the patch to use the specified color, and is one
 379        of `plain` (context text), `meta` (metainformation), `frag`
 380        (hunk header), `old` (removed lines), `new` (added lines),
 381        `commit` (commit headers), or `whitespace` (highlighting dubious
 382        whitespace).  The values of these variables may be specified as
 383        in color.branch.<slot>.
 384
 385color.pager::
 386        A boolean to enable/disable colored output when the pager is in
 387        use (default is true).
 388
 389color.status::
 390        A boolean to enable/disable color in the output of
 391        gitlink:git-status[1]. May be set to `true` (or `always`),
 392        `false` (or `never`) or `auto`, in which case colors are used
 393        only when the output is to a terminal. Defaults to false.
 394
 395color.status.<slot>::
 396        Use customized color for status colorization. `<slot>` is
 397        one of `header` (the header text of the status message),
 398        `added` or `updated` (files which are added but not committed),
 399        `changed` (files which are changed but not added in the index),
 400        or `untracked` (files which are not tracked by git). The values of
 401        these variables may be specified as in color.branch.<slot>.
 402
 403commit.template::
 404        Specify a file to use as the template for new commit messages.
 405
 406diff.autorefreshindex::
 407        When using `git diff` to compare with work tree
 408        files, do not consider stat-only change as changed.
 409        Instead, silently run `git update-index --refresh` to
 410        update the cached stat information for paths whose
 411        contents in the work tree match the contents in the
 412        index.  This option defaults to true.  Note that this
 413        affects only `git diff` Porcelain, and not lower level
 414        `diff` commands, such as `git diff-files`.
 415
 416diff.renameLimit::
 417        The number of files to consider when performing the copy/rename
 418        detection; equivalent to the git diff option '-l'.
 419
 420diff.renames::
 421        Tells git to detect renames.  If set to any boolean value, it
 422        will enable basic rename detection.  If set to "copies" or
 423        "copy", it will detect copies, as well.
 424
 425fetch.unpackLimit::
 426        If the number of objects fetched over the git native
 427        transfer is below this
 428        limit, then the objects will be unpacked into loose object
 429        files. However if the number of received objects equals or
 430        exceeds this limit then the received pack will be stored as
 431        a pack, after adding any missing delta bases.  Storing the
 432        pack from a push can make the push operation complete faster,
 433        especially on slow filesystems.
 434
 435format.numbered::
 436        A boolean which can enable sequence numbers in patch subjects.
 437        Seting this option to "auto" will enable it only if there is
 438        more than one patch.  See --numbered option in
 439        gitlink:git-format-patch[1].
 440
 441format.headers::
 442        Additional email headers to include in a patch to be submitted
 443        by mail.  See gitlink:git-format-patch[1].
 444
 445format.suffix::
 446        The default for format-patch is to output files with the suffix
 447        `.patch`. Use this variable to change that suffix (make sure to
 448        include the dot if you want it).
 449
 450gc.aggressiveWindow::
 451        The window size parameter used in the delta compression
 452        algorithm used by 'git gc --aggressive'.  This defaults
 453        to 10.
 454
 455gc.auto::
 456        When there are approximately more than this many loose
 457        objects in the repository, `git gc --auto` will pack them.
 458        Some Porcelain commands use this command to perform a
 459        light-weight garbage collection from time to time.  Setting
 460        this to 0 disables it.
 461
 462gc.autopacklimit::
 463        When there are more than this many packs that are not
 464        marked with `*.keep` file in the repository, `git gc
 465        --auto` consolidates them into one larger pack.  Setting
 466        this to 0 disables this.
 467
 468gc.packrefs::
 469        `git gc` does not run `git pack-refs` in a bare repository by
 470        default so that older dumb-transport clients can still fetch
 471        from the repository.  Setting this to `true` lets `git
 472        gc` to run `git pack-refs`.  Setting this to `false` tells
 473        `git gc` never to run `git pack-refs`. The default setting is
 474        `notbare`. Enable it only when you know you do not have to
 475        support such clients.  The default setting will change to `true`
 476        at some stage, and setting this to `false` will continue to
 477        prevent `git pack-refs` from being run from `git gc`.
 478
 479gc.reflogexpire::
 480        `git reflog expire` removes reflog entries older than
 481        this time; defaults to 90 days.
 482
 483gc.reflogexpireunreachable::
 484        `git reflog expire` removes reflog entries older than
 485        this time and are not reachable from the current tip;
 486        defaults to 30 days.
 487
 488gc.rerereresolved::
 489        Records of conflicted merge you resolved earlier are
 490        kept for this many days when `git rerere gc` is run.
 491        The default is 60 days.  See gitlink:git-rerere[1].
 492
 493gc.rerereunresolved::
 494        Records of conflicted merge you have not resolved are
 495        kept for this many days when `git rerere gc` is run.
 496        The default is 15 days.  See gitlink:git-rerere[1].
 497
 498rerere.enabled::
 499        Activate recording of resolved conflicts, so that identical
 500        conflict hunks can be resolved automatically, should they
 501        be encountered again.  See gitlink:git-rerere[1].
 502
 503gitcvs.enabled::
 504        Whether the CVS server interface is enabled for this repository.
 505        See gitlink:git-cvsserver[1].
 506
 507gitcvs.logfile::
 508        Path to a log file where the CVS server interface well... logs
 509        various stuff. See gitlink:git-cvsserver[1].
 510
 511gitcvs.allbinary::
 512        If true, all files are sent to the client in mode '-kb'. This
 513        causes the client to treat all files as binary files which suppresses
 514        any newline munging it otherwise might do. A work-around for the
 515        fact that there is no way yet to set single files to mode '-kb'.
 516
 517gitcvs.dbname::
 518        Database used by git-cvsserver to cache revision information
 519        derived from the git repository. The exact meaning depends on the
 520        used database driver, for SQLite (which is the default driver) this
 521        is a filename. Supports variable substitution (see
 522        gitlink:git-cvsserver[1] for details). May not contain semicolons (`;`).
 523        Default: '%Ggitcvs.%m.sqlite'
 524
 525gitcvs.dbdriver::
 526        Used Perl DBI driver. You can specify any available driver
 527        for this here, but it might not work. git-cvsserver is tested
 528        with 'DBD::SQLite', reported to work with 'DBD::Pg', and
 529        reported *not* to work with 'DBD::mysql'. Experimental feature.
 530        May not contain double colons (`:`). Default: 'SQLite'.
 531        See gitlink:git-cvsserver[1].
 532
 533gitcvs.dbuser, gitcvs.dbpass::
 534        Database user and password. Only useful if setting 'gitcvs.dbdriver',
 535        since SQLite has no concept of database users and/or passwords.
 536        'gitcvs.dbuser' supports variable substitution (see
 537        gitlink:git-cvsserver[1] for details).
 538
 539All gitcvs variables except for 'gitcvs.allbinary' can also be
 540specified as 'gitcvs.<access_method>.<varname>' (where 'access_method'
 541is one of "ext" and "pserver") to make them apply only for the given
 542access method.
 543
 544http.sslVerify::
 545        Whether to verify the SSL certificate when fetching or pushing
 546        over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
 547        variable.
 548
 549http.sslCert::
 550        File containing the SSL certificate when fetching or pushing
 551        over HTTPS. Can be overridden by the 'GIT_SSL_CERT' environment
 552        variable.
 553
 554http.sslKey::
 555        File containing the SSL private key when fetching or pushing
 556        over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment
 557        variable.
 558
 559http.sslCAInfo::
 560        File containing the certificates to verify the peer with when
 561        fetching or pushing over HTTPS. Can be overridden by the
 562        'GIT_SSL_CAINFO' environment variable.
 563
 564http.sslCAPath::
 565        Path containing files with the CA certificates to verify the peer
 566        with when fetching or pushing over HTTPS. Can be overridden
 567        by the 'GIT_SSL_CAPATH' environment variable.
 568
 569http.maxRequests::
 570        How many HTTP requests to launch in parallel. Can be overridden
 571        by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5.
 572
 573http.lowSpeedLimit, http.lowSpeedTime::
 574        If the HTTP transfer speed is less than 'http.lowSpeedLimit'
 575        for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
 576        Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and
 577        'GIT_HTTP_LOW_SPEED_TIME' environment variables.
 578
 579http.noEPSV::
 580        A boolean which disables using of EPSV ftp command by curl.
 581        This can helpful with some "poor" ftp servers which don't
 582        support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
 583        environment variable. Default is false (curl will use EPSV).
 584
 585i18n.commitEncoding::
 586        Character encoding the commit messages are stored in; git itself
 587        does not care per se, but this information is necessary e.g. when
 588        importing commits from emails or in the gitk graphical history
 589        browser (and possibly at other places in the future or in other
 590        porcelains). See e.g. gitlink:git-mailinfo[1]. Defaults to 'utf-8'.
 591
 592i18n.logOutputEncoding::
 593        Character encoding the commit messages are converted to when
 594        running `git-log` and friends.
 595
 596log.showroot::
 597        If true, the initial commit will be shown as a big creation event.
 598        This is equivalent to a diff against an empty tree.
 599        Tools like gitlink:git-log[1] or gitlink:git-whatchanged[1], which
 600        normally hide the root commit will now show it. True by default.
 601
 602merge.summary::
 603        Whether to include summaries of merged commits in newly created
 604        merge commit messages. False by default.
 605
 606merge.tool::
 607        Controls which merge resolution program is used by
 608        gitlink:git-mergetool[1].  Valid values are: "kdiff3", "tkdiff",
 609        "meld", "xxdiff", "emerge", "vimdiff", "gvimdiff", and "opendiff".
 610
 611merge.verbosity::
 612        Controls the amount of output shown by the recursive merge
 613        strategy.  Level 0 outputs nothing except a final error
 614        message if conflicts were detected. Level 1 outputs only
 615        conflicts, 2 outputs conflicts and file changes.  Level 5 and
 616        above outputs debugging information.  The default is level 2.
 617        Can be overridden by 'GIT_MERGE_VERBOSITY' environment variable.
 618
 619merge.<driver>.name::
 620        Defines a human readable name for a custom low-level
 621        merge driver.  See gitlink:gitattributes[5] for details.
 622
 623merge.<driver>.driver::
 624        Defines the command that implements a custom low-level
 625        merge driver.  See gitlink:gitattributes[5] for details.
 626
 627merge.<driver>.recursive::
 628        Names a low-level merge driver to be used when
 629        performing an internal merge between common ancestors.
 630        See gitlink:gitattributes[5] for details.
 631
 632pack.window::
 633        The size of the window used by gitlink:git-pack-objects[1] when no
 634        window size is given on the command line. Defaults to 10.
 635
 636pack.depth::
 637        The maximum delta depth used by gitlink:git-pack-objects[1] when no
 638        maximum depth is given on the command line. Defaults to 50.
 639
 640pack.windowMemory::
 641        The window memory size limit used by gitlink:git-pack-objects[1]
 642        when no limit is given on the command line.  The value can be
 643        suffixed with "k", "m", or "g".  Defaults to 0, meaning no
 644        limit.
 645
 646pack.compression::
 647        An integer -1..9, indicating the compression level for objects
 648        in a pack file. -1 is the zlib default. 0 means no
 649        compression, and 1..9 are various speed/size tradeoffs, 9 being
 650        slowest.  If not set,  defaults to core.compression.  If that is
 651        not set,  defaults to -1.
 652
 653pack.deltaCacheSize::
 654        The maximum memory in bytes used for caching deltas in
 655        gitlink:git-pack-objects[1].
 656        A value of 0 means no limit. Defaults to 0.
 657
 658pack.deltaCacheLimit::
 659        The maximum size of a delta, that is cached in
 660        gitlink:git-pack-objects[1]. Defaults to 1000.
 661
 662pack.threads::
 663        Specifies the number of threads to spawn when searching for best
 664        delta matches.  This requires that gitlink:git-pack-objects[1]
 665        be compiled with pthreads otherwise this option is ignored with a
 666        warning. This is meant to reduce packing time on multiprocessor
 667        machines. The required amount of memory for the delta search window
 668        is however multiplied by the number of threads.
 669
 670pack.indexVersion::
 671        Specify the default pack index version.  Valid values are 1 for
 672        legacy pack index used by Git versions prior to 1.5.2, and 2 for
 673        the new pack index with capabilities for packs larger than 4 GB
 674        as well as proper protection against the repacking of corrupted
 675        packs.  Version 2 is selected and this config option ignored
 676        whenever the corresponding pack is larger than 2 GB.  Otherwise
 677        the default is 1.
 678
 679pull.octopus::
 680        The default merge strategy to use when pulling multiple branches
 681        at once.
 682
 683pull.twohead::
 684        The default merge strategy to use when pulling a single branch.
 685
 686remote.<name>.url::
 687        The URL of a remote repository.  See gitlink:git-fetch[1] or
 688        gitlink:git-push[1].
 689
 690remote.<name>.fetch::
 691        The default set of "refspec" for gitlink:git-fetch[1]. See
 692        gitlink:git-fetch[1].
 693
 694remote.<name>.push::
 695        The default set of "refspec" for gitlink:git-push[1]. See
 696        gitlink:git-push[1].
 697
 698remote.<name>.skipDefaultUpdate::
 699        If true, this remote will be skipped by default when updating
 700        using the remote subcommand of gitlink:git-remote[1].
 701
 702remote.<name>.receivepack::
 703        The default program to execute on the remote side when pushing.  See
 704        option \--exec of gitlink:git-push[1].
 705
 706remote.<name>.uploadpack::
 707        The default program to execute on the remote side when fetching.  See
 708        option \--exec of gitlink:git-fetch-pack[1].
 709
 710remote.<name>.tagopt::
 711        Setting this value to --no-tags disables automatic tag following when fetching
 712        from remote <name>
 713
 714remotes.<group>::
 715        The list of remotes which are fetched by "git remote update
 716        <group>".  See gitlink:git-remote[1].
 717
 718repack.usedeltabaseoffset::
 719        Allow gitlink:git-repack[1] to create packs that uses
 720        delta-base offset.  Defaults to false.
 721
 722show.difftree::
 723        The default gitlink:git-diff-tree[1] arguments to be used
 724        for gitlink:git-show[1].
 725
 726showbranch.default::
 727        The default set of branches for gitlink:git-show-branch[1].
 728        See gitlink:git-show-branch[1].
 729
 730tar.umask::
 731        This variable can be used to restrict the permission bits of
 732        tar archive entries.  The default is 0002, which turns off the
 733        world write bit.  The special value "user" indicates that the
 734        archiving user's umask will be used instead.  See umask(2) and
 735        gitlink:git-archive[1].
 736
 737user.email::
 738        Your email address to be recorded in any newly created commits.
 739        Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and
 740        'EMAIL' environment variables.  See gitlink:git-commit-tree[1].
 741
 742user.name::
 743        Your full name to be recorded in any newly created commits.
 744        Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
 745        environment variables.  See gitlink:git-commit-tree[1].
 746
 747user.signingkey::
 748        If gitlink:git-tag[1] is not selecting the key you want it to
 749        automatically when creating a signed tag, you can override the
 750        default selection with this variable.  This option is passed
 751        unchanged to gpg's --local-user parameter, so you may specify a key
 752        using any method that gpg supports.
 753
 754whatchanged.difftree::
 755        The default gitlink:git-diff-tree[1] arguments to be used
 756        for gitlink:git-whatchanged[1].
 757
 758imap::
 759        The configuration variables in the 'imap' section are described
 760        in gitlink:git-imap-send[1].
 761
 762receive.unpackLimit::
 763        If the number of objects received in a push is below this
 764        limit then the objects will be unpacked into loose object
 765        files. However if the number of received objects equals or
 766        exceeds this limit then the received pack will be stored as
 767        a pack, after adding any missing delta bases.  Storing the
 768        pack from a push can make the push operation complete faster,
 769        especially on slow filesystems.
 770
 771receive.denyNonFastForwards::
 772        If set to true, git-receive-pack will deny a ref update which is
 773        not a fast forward. Use this to prevent such an update via a push,
 774        even if that push is forced. This configuration variable is
 775        set when initializing a shared repository.
 776
 777transfer.unpackLimit::
 778        When `fetch.unpackLimit` or `receive.unpackLimit` are
 779        not set, the value of this variable is used instead.
