   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. $GIT_DIR is not set).
 191        This can be overriden by the GIT_WORK_TREE environment
 192        variable and the '--work-tree' command line option.
 193
 194core.logAllRefUpdates::
 195        Updates to a ref <ref> is logged to the file
 196        "$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.excludeFile::
 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
 284alias.*::
 285        Command aliases for the gitlink:git[1] command wrapper - e.g.
 286        after defining "alias.last = cat-file commit HEAD", the invocation
 287        "git last" is equivalent to "git cat-file commit HEAD". To avoid
 288        confusion and troubles with script usage, aliases that
 289        hide existing git commands are ignored. Arguments are split by
 290        spaces, the usual shell quoting and escaping is supported.
 291        quote pair and a backslash can be used to quote them.
 292
 293        If the alias expansion is prefixed with an exclamation point,
 294        it will be treated as a shell command.  For example, defining
 295        "alias.new = !gitk --all --not ORIG_HEAD", the invocation
 296        "git new" is equivalent to running the shell command
 297        "gitk --all --not ORIG_HEAD".
 298
 299apply.whitespace::
 300        Tells `git-apply` how to handle whitespaces, in the same way
 301        as the '--whitespace' option. See gitlink:git-apply[1].
 302
 303branch.autosetupmerge::
 304        Tells `git-branch` and `git-checkout` to setup new branches
 305        so that gitlink:git-pull[1] will appropriately merge from that
 306        remote branch.  Note that even if this option is not set,
 307        this behavior can be chosen per-branch using the `--track`
 308        and `--no-track` options.  This option defaults to false.
 309
 310branch.<name>.remote::
 311        When in branch <name>, it tells `git fetch` which remote to fetch.
 312        If this option is not given, `git fetch` defaults to remote "origin".
 313
 314branch.<name>.merge::
 315        When in branch <name>, it tells `git fetch` the default refspec to
 316        be marked for merging in FETCH_HEAD. The value has exactly to match
 317        a remote part of one of the refspecs which are fetched from the remote
 318        given by "branch.<name>.remote".
 319        The merge information is used by `git pull` (which at first calls
 320        `git fetch`) to lookup the default branch for merging. Without
 321        this option, `git pull` defaults to merge the first refspec fetched.
 322        Specify multiple values to get an octopus merge.
 323        If you wish to setup `git pull` so that it merges into <name> from
 324        another branch in the local repository, you can point
 325        branch.<name>.merge to the desired branch, and use the special setting
 326        `.` (a period) for branch.<name>.remote.
 327
 328clean.requireForce::
 329        A boolean to make git-clean do nothing unless given -f or -n.  Defaults
 330        to false.
 331
 332color.branch::
 333        A boolean to enable/disable color in the output of
 334        gitlink:git-branch[1]. May be set to `true` (or `always`),
 335        `false` (or `never`) or `auto`, in which case colors are used
 336        only when the output is to a terminal. Defaults to false.
 337
 338color.branch.<slot>::
 339        Use customized color for branch coloration. `<slot>` is one of
 340        `current` (the current branch), `local` (a local branch),
 341        `remote` (a tracking branch in refs/remotes/), `plain` (other
 342        refs).
 343+
 344The value for these configuration variables is a list of colors (at most
 345two) and attributes (at most one), separated by spaces.  The colors
 346accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`,
 347`magenta`, `cyan` and `white`; the attributes are `bold`, `dim`, `ul`,
 348`blink` and `reverse`.  The first color given is the foreground; the
 349second is the background.  The position of the attribute, if any,
 350doesn't matter.
 351
 352color.diff::
 353        When true (or `always`), always use colors in patch.
 354        When false (or `never`), never.  When set to `auto`, use
 355        colors only when the output is to the terminal.
 356
 357color.diff.<slot>::
 358        Use customized color for diff colorization.  `<slot>` specifies
 359        which part of the patch to use the specified color, and is one
 360        of `plain` (context text), `meta` (metainformation), `frag`
 361        (hunk header), `old` (removed lines), `new` (added lines),
 362        `commit` (commit headers), or `whitespace` (highlighting dubious
 363        whitespace).  The values of these variables may be specified as
 364        in color.branch.<slot>.
 365
 366color.pager::
 367        A boolean to enable/disable colored output when the pager is in
 368        use (default is true).
 369
 370color.status::
 371        A boolean to enable/disable color in the output of
 372        gitlink:git-status[1]. May be set to `true` (or `always`),
 373        `false` (or `never`) or `auto`, in which case colors are used
 374        only when the output is to a terminal. Defaults to false.
 375
 376color.status.<slot>::
 377        Use customized color for status colorization. `<slot>` is
 378        one of `header` (the header text of the status message),
 379        `added` or `updated` (files which are added but not committed),
 380        `changed` (files which are changed but not added in the index),
 381        or `untracked` (files which are not tracked by git). The values of
 382        these variables may be specified as in color.branch.<slot>.
 383
 384diff.renameLimit::
 385        The number of files to consider when performing the copy/rename
 386        detection; equivalent to the git diff option '-l'.
 387
 388diff.renames::
 389        Tells git to detect renames.  If set to any boolean value, it
 390        will enable basic rename detection.  If set to "copies" or
 391        "copy", it will detect copies, as well.
 392
 393fetch.unpackLimit::
 394        If the number of objects fetched over the git native
 395        transfer is below this
 396        limit, then the objects will be unpacked into loose object
 397        files. However if the number of received objects equals or
 398        exceeds this limit then the received pack will be stored as
 399        a pack, after adding any missing delta bases.  Storing the
 400        pack from a push can make the push operation complete faster,
 401        especially on slow filesystems.
 402
 403format.headers::
 404        Additional email headers to include in a patch to be submitted
 405        by mail.  See gitlink:git-format-patch[1].
 406
 407format.suffix::
 408        The default for format-patch is to output files with the suffix
 409        `.patch`. Use this variable to change that suffix (make sure to
 410        include the dot if you want it).
 411
 412gc.aggressiveWindow::
 413        The window size parameter used in the delta compression
 414        algorithm used by 'git gc --aggressive'.  This defaults
 415        to 10.
 416
 417gc.packrefs::
 418        `git gc` does not run `git pack-refs` in a bare repository by
 419        default so that older dumb-transport clients can still fetch
 420        from the repository.  Setting this to `true` lets `git
 421        gc` to run `git pack-refs`.  Setting this to `false` tells
 422        `git gc` never to run `git pack-refs`. The default setting is
 423        `notbare`. Enable it only when you know you do not have to
 424        support such clients.  The default setting will change to `true`
 425        at some stage, and setting this to `false` will continue to
 426        prevent `git pack-refs` from being run from `git gc`.
 427
 428gc.reflogexpire::
 429        `git reflog expire` removes reflog entries older than
 430        this time; defaults to 90 days.
 431
 432gc.reflogexpireunreachable::
 433        `git reflog expire` removes reflog entries older than
 434        this time and are not reachable from the current tip;
 435        defaults to 30 days.
 436
 437gc.rerereresolved::
 438        Records of conflicted merge you resolved earlier are
 439        kept for this many days when `git rerere gc` is run.
 440        The default is 60 days.  See gitlink:git-rerere[1].
 441
 442gc.rerereunresolved::
 443        Records of conflicted merge you have not resolved are
 444        kept for this many days when `git rerere gc` is run.
 445        The default is 15 days.  See gitlink:git-rerere[1].
 446
 447gitcvs.enabled::
 448        Whether the cvs server interface is enabled for this repository.
 449        See gitlink:git-cvsserver[1].
 450
 451gitcvs.logfile::
 452        Path to a log file where the cvs server interface well... logs
 453        various stuff. See gitlink:git-cvsserver[1].
 454
 455gitcvs.allbinary::
 456        If true, all files are sent to the client in mode '-kb'. This
 457        causes the client to treat all files as binary files which suppresses
 458        any newline munging it otherwise might do. A work-around for the
 459        fact that there is no way yet to set single files to mode '-kb'.
 460
 461gitcvs.dbname::
 462        Database used by git-cvsserver to cache revision information
 463        derived from the git repository. The exact meaning depends on the
 464        used database driver, for SQLite (which is the default driver) this
 465        is a filename. Supports variable substitution (see
 466        gitlink:git-cvsserver[1] for details). May not contain semicolons (`;`).
 467        Default: '%Ggitcvs.%m.sqlite'
 468
 469gitcvs.dbdriver::
 470        Used Perl DBI driver. You can specify any available driver
 471        for this here, but it might not work. git-cvsserver is tested
 472        with 'DBD::SQLite', reported to work with 'DBD::Pg', and
 473        reported *not* to work with 'DBD::mysql'. Experimental feature.
 474        May not contain double colons (`:`). Default: 'SQLite'.
 475        See gitlink:git-cvsserver[1].
 476
 477gitcvs.dbuser, gitcvs.dbpass::
 478        Database user and password. Only useful if setting 'gitcvs.dbdriver',
 479        since SQLite has no concept of database users and/or passwords.
 480        'gitcvs.dbuser' supports variable substitution (see
 481        gitlink:git-cvsserver[1] for details).
 482
 483All gitcvs variables except for 'gitcvs.allbinary' can also specifed
 484as 'gitcvs.<access_method>.<varname>' (where 'access_method' is one
 485of "ext" and "pserver") to make them apply only for the given access
 486method.
 487
 488http.sslVerify::
 489        Whether to verify the SSL certificate when fetching or pushing
 490        over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
 491        variable.
 492
 493http.sslCert::
 494        File containing the SSL certificate when fetching or pushing
 495        over HTTPS. Can be overridden by the 'GIT_SSL_CERT' environment
 496        variable.
 497
 498http.sslKey::
 499        File containing the SSL private key when fetching or pushing
 500        over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment
 501        variable.
 502
 503http.sslCAInfo::
 504        File containing the certificates to verify the peer with when
 505        fetching or pushing over HTTPS. Can be overridden by the
 506        'GIT_SSL_CAINFO' environment variable.
 507
 508http.sslCAPath::
 509        Path containing files with the CA certificates to verify the peer
 510        with when fetching or pushing over HTTPS. Can be overridden
 511        by the 'GIT_SSL_CAPATH' environment variable.
 512
 513http.maxRequests::
 514        How many HTTP requests to launch in parallel. Can be overridden
 515        by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5.
 516
 517http.lowSpeedLimit, http.lowSpeedTime::
 518        If the HTTP transfer speed is less than 'http.lowSpeedLimit'
 519        for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
 520        Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and
 521        'GIT_HTTP_LOW_SPEED_TIME' environment variables.
 522
 523http.noEPSV::
 524        A boolean which disables using of EPSV ftp command by curl.
 525        This can helpful with some "poor" ftp servers which don't
 526        support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
 527        environment variable. Default is false (curl will use EPSV).
 528
 529i18n.commitEncoding::
 530        Character encoding the commit messages are stored in; git itself
 531        does not care per se, but this information is necessary e.g. when
 532        importing commits from emails or in the gitk graphical history
 533        browser (and possibly at other places in the future or in other
 534        porcelains). See e.g. gitlink:git-mailinfo[1]. Defaults to 'utf-8'.
 535
 536i18n.logOutputEncoding::
 537        Character encoding the commit messages are converted to when
 538        running `git-log` and friends.
 539
 540log.showroot::
 541        If true, the initial commit will be shown as a big creation event.
 542        This is equivalent to a diff against an empty tree.
 543        Tools like gitlink:git-log[1] or gitlink:git-whatchanged[1], which
 544        normally hide the root commit will now show it. True by default.
 545
 546merge.summary::
 547        Whether to include summaries of merged commits in newly created
 548        merge commit messages. False by default.
 549
 550merge.tool::
 551        Controls which merge resolution program is used by
 552        gitlink:git-mergetool[l].  Valid values are: "kdiff3", "tkdiff",
 553        "meld", "xxdiff", "emerge", "vimdiff", "gvimdiff", and "opendiff".
 554
 555merge.verbosity::
 556        Controls the amount of output shown by the recursive merge
 557        strategy.  Level 0 outputs nothing except a final error
 558        message if conflicts were detected. Level 1 outputs only
 559        conflicts, 2 outputs conflicts and file changes.  Level 5 and
 560        above outputs debugging information.  The default is level 2.
 561
 562merge.<driver>.name::
 563        Defines a human readable name for a custom low-level
 564        merge driver.  See gitlink:gitattributes[5] for details.
 565
 566merge.<driver>.driver::
 567        Defines the command that implements a custom low-level
 568        merge driver.  See gitlink:gitattributes[5] for details.
 569
 570merge.<driver>.recursive::
 571        Names a low-level merge driver to be used when
 572        performing an internal merge between common ancestors.
 573        See gitlink:gitattributes[5] for details.
 574
 575pack.window::
 576        The size of the window used by gitlink:git-pack-objects[1] when no
 577        window size is given on the command line. Defaults to 10.
 578
 579pack.depth::
 580        The maximum delta depth used by gitlink:git-pack-objects[1] when no
 581        maximum depth is given on the command line. Defaults to 50.
 582
 583pack.compression::
 584        An integer -1..9, indicating the compression level for objects
 585        in a pack file. -1 is the zlib default. 0 means no
 586        compression, and 1..9 are various speed/size tradeoffs, 9 being
 587        slowest.  If not set,  defaults to core.compression.  If that is
 588        not set,  defaults to -1.
 589
 590pack.deltaCacheSize::
 591        The maxium memory in bytes used for caching deltas in
 592        gitlink:git-pack-objects[1].
 593        A value of 0 means no limit. Defaults to 0.
 594
 595pack.deltaCacheLimit::
 596        The maxium size of a delta, that is cached in
 597        gitlink:git-pack-objects[1]. Defaults to 1000.
 598
 599pull.octopus::
 600        The default merge strategy to use when pulling multiple branches
 601        at once.
 602
 603pull.twohead::
 604        The default merge strategy to use when pulling a single branch.
 605
 606remote.<name>.url::
 607        The URL of a remote repository.  See gitlink:git-fetch[1] or
 608        gitlink:git-push[1].
 609
 610remote.<name>.fetch::
 611        The default set of "refspec" for gitlink:git-fetch[1]. See
 612        gitlink:git-fetch[1].
 613
 614remote.<name>.push::
 615        The default set of "refspec" for gitlink:git-push[1]. See
 616        gitlink:git-push[1].
 617
 618remote.<name>.skipDefaultUpdate::
 619        If true, this remote will be skipped by default when updating
 620        using the remote subcommand of gitlink:git-remote[1].
 621
 622remote.<name>.receivepack::
 623        The default program to execute on the remote side when pushing.  See
 624        option \--exec of gitlink:git-push[1].
 625
 626remote.<name>.uploadpack::
 627        The default program to execute on the remote side when fetching.  See
 628        option \--exec of gitlink:git-fetch-pack[1].
 629
 630remote.<name>.tagopt::
 631        Setting this value to --no-tags disables automatic tag following when fetching
 632        from remote <name>
 633
 634remotes.<group>::
 635        The list of remotes which are fetched by "git remote update
 636        <group>".  See gitlink:git-remote[1].
 637
 638repack.usedeltabaseoffset::
 639        Allow gitlink:git-repack[1] to create packs that uses
 640        delta-base offset.  Defaults to false.
 641
 642show.difftree::
 643        The default gitlink:git-diff-tree[1] arguments to be used
 644        for gitlink:git-show[1].
 645
 646showbranch.default::
 647        The default set of branches for gitlink:git-show-branch[1].
 648        See gitlink:git-show-branch[1].
 649
 650tar.umask::
 651        By default, gitlink:git-tar-tree[1] sets file and directories modes
 652        to 0666 or 0777. While this is both useful and acceptable for projects
 653        such as the Linux Kernel, it might be excessive for other projects.
 654        With this variable, it becomes possible to tell
 655        gitlink:git-tar-tree[1] to apply a specific umask to the modes above.
 656        The special value "user" indicates that the user's current umask will
 657        be used. This should be enough for most projects, as it will lead to
 658        the same permissions as gitlink:git-checkout[1] would use. The default
 659        value remains 0, which means world read-write.
 660
 661user.email::
 662        Your email address to be recorded in any newly created commits.
 663        Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and
 664        'EMAIL' environment variables.  See gitlink:git-commit-tree[1].
 665
 666user.name::
 667        Your full name to be recorded in any newly created commits.
 668        Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
 669        environment variables.  See gitlink:git-commit-tree[1].
 670
 671user.signingkey::
 672        If gitlink:git-tag[1] is not selecting the key you want it to
 673        automatically when creating a signed tag, you can override the
 674        default selection with this variable.  This option is passed
 675        unchanged to gpg's --local-user parameter, so you may specify a key
 676        using any method that gpg supports.
 677
 678whatchanged.difftree::
 679        The default gitlink:git-diff-tree[1] arguments to be used
 680        for gitlink:git-whatchanged[1].
 681
 682imap::
 683        The configuration variables in the 'imap' section are described
 684        in gitlink:git-imap-send[1].
 685
 686receive.unpackLimit::
 687        If the number of objects received in a push is below this
 688        limit then the objects will be unpacked into loose object
 689        files. However if the number of received objects equals or
 690        exceeds this limit then the received pack will be stored as
 691        a pack, after adding any missing delta bases.  Storing the
 692        pack from a push can make the push operation complete faster,
 693        especially on slow filesystems.
 694
 695receive.denyNonFastForwards::
 696        If set to true, git-receive-pack will deny a ref update which is
 697        not a fast forward. Use this to prevent such an update via a push,
 698        even if that push is forced. This configuration variable is
 699        set when initializing a shared repository.
 700
 701transfer.unpackLimit::
 702        When `fetch.unpackLimit` or `receive.unpackLimit` are
 703        not set, the value of this variable is used instead.
