   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 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.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 lauching 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
 305        If the alias expansion is prefixed with an exclamation point,
 306        it 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 refspec to
 328        be marked for merging in FETCH_HEAD. The value has exactly to match
 329        a remote part of one of the refspecs which are fetched from the remote
 330        given by "branch.<name>.remote".
 331        The merge information is used by `git pull` (which at first calls
 332        `git fetch`) to lookup the default branch for merging. Without
 333        this option, `git pull` defaults to merge the first refspec fetched.
 334        Specify multiple values to get an octopus merge.
 335        If you wish to setup `git pull` so that it merges into <name> from
 336        another branch in the local repository, you can point
 337        branch.<name>.merge to the desired branch, and use the special setting
 338        `.` (a period) for branch.<name>.remote.
 339
 340clean.requireForce::
 341        A boolean to make git-clean do nothing unless given -f or -n.  Defaults
 342        to false.
 343
 344color.branch::
 345        A boolean to enable/disable color in the output of
 346        gitlink:git-branch[1]. May be set to `true` (or `always`),
 347        `false` (or `never`) or `auto`, in which case colors are used
 348        only when the output is to a terminal. Defaults to false.
 349
 350color.branch.<slot>::
 351        Use customized color for branch coloration. `<slot>` is one of
 352        `current` (the current branch), `local` (a local branch),
 353        `remote` (a tracking branch in refs/remotes/), `plain` (other
 354        refs).
 355+
 356The value for these configuration variables is a list of colors (at most
 357two) and attributes (at most one), separated by spaces.  The colors
 358accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`,
 359`magenta`, `cyan` and `white`; the attributes are `bold`, `dim`, `ul`,
 360`blink` and `reverse`.  The first color given is the foreground; the
 361second is the background.  The position of the attribute, if any,
 362doesn't matter.
 363
 364color.diff::
 365        When true (or `always`), always use colors in patch.
 366        When false (or `never`), never.  When set to `auto`, use
 367        colors only when the output is to the terminal.
 368
 369color.diff.<slot>::
 370        Use customized color for diff colorization.  `<slot>` specifies
 371        which part of the patch to use the specified color, and is one
 372        of `plain` (context text), `meta` (metainformation), `frag`
 373        (hunk header), `old` (removed lines), `new` (added lines),
 374        `commit` (commit headers), or `whitespace` (highlighting dubious
 375        whitespace).  The values of these variables may be specified as
 376        in color.branch.<slot>.
 377
 378color.pager::
 379        A boolean to enable/disable colored output when the pager is in
 380        use (default is true).
 381
 382color.status::
 383        A boolean to enable/disable color in the output of
 384        gitlink:git-status[1]. May be set to `true` (or `always`),
 385        `false` (or `never`) or `auto`, in which case colors are used
 386        only when the output is to a terminal. Defaults to false.
 387
 388color.status.<slot>::
 389        Use customized color for status colorization. `<slot>` is
 390        one of `header` (the header text of the status message),
 391        `added` or `updated` (files which are added but not committed),
 392        `changed` (files which are changed but not added in the index),
 393        or `untracked` (files which are not tracked by git). The values of
 394        these variables may be specified as in color.branch.<slot>.
 395
 396commit.template::
 397        Specify a file to use as the template for new commit messages.
 398
 399diff.renameLimit::
 400        The number of files to consider when performing the copy/rename
 401        detection; equivalent to the git diff option '-l'.
 402
 403diff.renames::
 404        Tells git to detect renames.  If set to any boolean value, it
 405        will enable basic rename detection.  If set to "copies" or
 406        "copy", it will detect copies, as well.
 407
 408fetch.unpackLimit::
 409        If the number of objects fetched over the git native
 410        transfer is below this
 411        limit, then the objects will be unpacked into loose object
 412        files. However if the number of received objects equals or
 413        exceeds this limit then the received pack will be stored as
 414        a pack, after adding any missing delta bases.  Storing the
 415        pack from a push can make the push operation complete faster,
 416        especially on slow filesystems.
 417
 418format.headers::
 419        Additional email headers to include in a patch to be submitted
 420        by mail.  See gitlink:git-format-patch[1].
 421
 422format.suffix::
 423        The default for format-patch is to output files with the suffix
 424        `.patch`. Use this variable to change that suffix (make sure to
 425        include the dot if you want it).
 426
 427gc.aggressiveWindow::
 428        The window size parameter used in the delta compression
 429        algorithm used by 'git gc --aggressive'.  This defaults
 430        to 10.
 431
 432gc.packrefs::
 433        `git gc` does not run `git pack-refs` in a bare repository by
 434        default so that older dumb-transport clients can still fetch
 435        from the repository.  Setting this to `true` lets `git
 436        gc` to run `git pack-refs`.  Setting this to `false` tells
 437        `git gc` never to run `git pack-refs`. The default setting is
 438        `notbare`. Enable it only when you know you do not have to
 439        support such clients.  The default setting will change to `true`
 440        at some stage, and setting this to `false` will continue to
 441        prevent `git pack-refs` from being run from `git gc`.
 442
 443gc.reflogexpire::
 444        `git reflog expire` removes reflog entries older than
 445        this time; defaults to 90 days.
 446
 447gc.reflogexpireunreachable::
 448        `git reflog expire` removes reflog entries older than
 449        this time and are not reachable from the current tip;
 450        defaults to 30 days.
 451
 452gc.rerereresolved::
 453        Records of conflicted merge you resolved earlier are
 454        kept for this many days when `git rerere gc` is run.
 455        The default is 60 days.  See gitlink:git-rerere[1].
 456
 457gc.rerereunresolved::
 458        Records of conflicted merge you have not resolved are
 459        kept for this many days when `git rerere gc` is run.
 460        The default is 15 days.  See gitlink:git-rerere[1].
 461
 462rerere.enabled::
 463        Activate recording of resolved conflicts, so that identical
 464        conflict hunks can be resolved automatically, should they
 465        be encountered again.  See gitlink:git-rerere[1].
 466
 467gitcvs.enabled::
 468        Whether the cvs server interface is enabled for this repository.
 469        See gitlink:git-cvsserver[1].
 470
 471gitcvs.logfile::
 472        Path to a log file where the cvs server interface well... logs
 473        various stuff. See gitlink:git-cvsserver[1].
 474
 475gitcvs.allbinary::
 476        If true, all files are sent to the client in mode '-kb'. This
 477        causes the client to treat all files as binary files which suppresses
 478        any newline munging it otherwise might do. A work-around for the
 479        fact that there is no way yet to set single files to mode '-kb'.
 480
 481gitcvs.dbname::
 482        Database used by git-cvsserver to cache revision information
 483        derived from the git repository. The exact meaning depends on the
 484        used database driver, for SQLite (which is the default driver) this
 485        is a filename. Supports variable substitution (see
 486        gitlink:git-cvsserver[1] for details). May not contain semicolons (`;`).
 487        Default: '%Ggitcvs.%m.sqlite'
 488
 489gitcvs.dbdriver::
 490        Used Perl DBI driver. You can specify any available driver
 491        for this here, but it might not work. git-cvsserver is tested
 492        with 'DBD::SQLite', reported to work with 'DBD::Pg', and
 493        reported *not* to work with 'DBD::mysql'. Experimental feature.
 494        May not contain double colons (`:`). Default: 'SQLite'.
 495        See gitlink:git-cvsserver[1].
 496
 497gitcvs.dbuser, gitcvs.dbpass::
 498        Database user and password. Only useful if setting 'gitcvs.dbdriver',
 499        since SQLite has no concept of database users and/or passwords.
 500        'gitcvs.dbuser' supports variable substitution (see
 501        gitlink:git-cvsserver[1] for details).
 502
 503All gitcvs variables except for 'gitcvs.allbinary' can also specifed
 504as 'gitcvs.<access_method>.<varname>' (where 'access_method' is one
 505of "ext" and "pserver") to make them apply only for the given access
 506method.
 507
 508http.sslVerify::
 509        Whether to verify the SSL certificate when fetching or pushing
 510        over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
 511        variable.
 512
 513http.sslCert::
 514        File containing the SSL certificate when fetching or pushing
 515        over HTTPS. Can be overridden by the 'GIT_SSL_CERT' environment
 516        variable.
 517
 518http.sslKey::
 519        File containing the SSL private key when fetching or pushing
 520        over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment
 521        variable.
 522
 523http.sslCAInfo::
 524        File containing the certificates to verify the peer with when
 525        fetching or pushing over HTTPS. Can be overridden by the
 526        'GIT_SSL_CAINFO' environment variable.
 527
 528http.sslCAPath::
 529        Path containing files with the CA certificates to verify the peer
 530        with when fetching or pushing over HTTPS. Can be overridden
 531        by the 'GIT_SSL_CAPATH' environment variable.
 532
 533http.maxRequests::
 534        How many HTTP requests to launch in parallel. Can be overridden
 535        by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5.
 536
 537http.lowSpeedLimit, http.lowSpeedTime::
 538        If the HTTP transfer speed is less than 'http.lowSpeedLimit'
 539        for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
 540        Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and
 541        'GIT_HTTP_LOW_SPEED_TIME' environment variables.
 542
 543http.noEPSV::
 544        A boolean which disables using of EPSV ftp command by curl.
 545        This can helpful with some "poor" ftp servers which don't
 546        support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
 547        environment variable. Default is false (curl will use EPSV).
 548
 549i18n.commitEncoding::
 550        Character encoding the commit messages are stored in; git itself
 551        does not care per se, but this information is necessary e.g. when
 552        importing commits from emails or in the gitk graphical history
 553        browser (and possibly at other places in the future or in other
 554        porcelains). See e.g. gitlink:git-mailinfo[1]. Defaults to 'utf-8'.
 555
 556i18n.logOutputEncoding::
 557        Character encoding the commit messages are converted to when
 558        running `git-log` and friends.
 559
 560log.showroot::
 561        If true, the initial commit will be shown as a big creation event.
 562        This is equivalent to a diff against an empty tree.
 563        Tools like gitlink:git-log[1] or gitlink:git-whatchanged[1], which
 564        normally hide the root commit will now show it. True by default.
 565
 566merge.summary::
 567        Whether to include summaries of merged commits in newly created
 568        merge commit messages. False by default.
 569
 570merge.tool::
 571        Controls which merge resolution program is used by
 572        gitlink:git-mergetool[l].  Valid values are: "kdiff3", "tkdiff",
 573        "meld", "xxdiff", "emerge", "vimdiff", "gvimdiff", and "opendiff".
 574
 575merge.verbosity::
 576        Controls the amount of output shown by the recursive merge
 577        strategy.  Level 0 outputs nothing except a final error
 578        message if conflicts were detected. Level 1 outputs only
 579        conflicts, 2 outputs conflicts and file changes.  Level 5 and
 580        above outputs debugging information.  The default is level 2.
 581        Can be overriden by 'GIT_MERGE_VERBOSITY' environment variable.
 582
 583merge.<driver>.name::
 584        Defines a human readable name for a custom low-level
 585        merge driver.  See gitlink:gitattributes[5] for details.
 586
 587merge.<driver>.driver::
 588        Defines the command that implements a custom low-level
 589        merge driver.  See gitlink:gitattributes[5] for details.
 590
 591merge.<driver>.recursive::
 592        Names a low-level merge driver to be used when
 593        performing an internal merge between common ancestors.
 594        See gitlink:gitattributes[5] for details.
 595
 596pack.window::
 597        The size of the window used by gitlink:git-pack-objects[1] when no
 598        window size is given on the command line. Defaults to 10.
 599
 600pack.depth::
 601        The maximum delta depth used by gitlink:git-pack-objects[1] when no
 602        maximum depth is given on the command line. Defaults to 50.
 603
 604pack.windowMemory::
 605        The window memory size limit used by gitlink:git-pack-objects[1]
 606        when no limit is given on the command line.  The value can be
 607        suffixed with "k", "m", or "g".  Defaults to 0, meaning no
 608        limit.
 609
 610pack.compression::
 611        An integer -1..9, indicating the compression level for objects
 612        in a pack file. -1 is the zlib default. 0 means no
 613        compression, and 1..9 are various speed/size tradeoffs, 9 being
 614        slowest.  If not set,  defaults to core.compression.  If that is
 615        not set,  defaults to -1.
 616
 617pack.deltaCacheSize::
 618        The maxium memory in bytes used for caching deltas in
 619        gitlink:git-pack-objects[1].
 620        A value of 0 means no limit. Defaults to 0.
 621
 622pack.deltaCacheLimit::
 623        The maxium size of a delta, that is cached in
 624        gitlink:git-pack-objects[1]. Defaults to 1000.
 625
 626pull.octopus::
 627        The default merge strategy to use when pulling multiple branches
 628        at once.
 629
 630pull.twohead::
 631        The default merge strategy to use when pulling a single branch.
 632
 633remote.<name>.url::
 634        The URL of a remote repository.  See gitlink:git-fetch[1] or
 635        gitlink:git-push[1].
 636
 637remote.<name>.fetch::
 638        The default set of "refspec" for gitlink:git-fetch[1]. See
 639        gitlink:git-fetch[1].
 640
 641remote.<name>.push::
 642        The default set of "refspec" for gitlink:git-push[1]. See
 643        gitlink:git-push[1].
 644
 645remote.<name>.skipDefaultUpdate::
 646        If true, this remote will be skipped by default when updating
 647        using the remote subcommand of gitlink:git-remote[1].
 648
 649remote.<name>.receivepack::
 650        The default program to execute on the remote side when pushing.  See
 651        option \--exec of gitlink:git-push[1].
 652
 653remote.<name>.uploadpack::
 654        The default program to execute on the remote side when fetching.  See
 655        option \--exec of gitlink:git-fetch-pack[1].
 656
 657remote.<name>.tagopt::
 658        Setting this value to --no-tags disables automatic tag following when fetching
 659        from remote <name>
 660
 661remotes.<group>::
 662        The list of remotes which are fetched by "git remote update
 663        <group>".  See gitlink:git-remote[1].
 664
 665repack.usedeltabaseoffset::
 666        Allow gitlink:git-repack[1] to create packs that uses
 667        delta-base offset.  Defaults to false.
 668
 669show.difftree::
 670        The default gitlink:git-diff-tree[1] arguments to be used
 671        for gitlink:git-show[1].
 672
 673showbranch.default::
 674        The default set of branches for gitlink:git-show-branch[1].
 675        See gitlink:git-show-branch[1].
 676
 677tar.umask::
 678        By default, gitlink:git-tar-tree[1] sets file and directories modes
 679        to 0666 or 0777. While this is both useful and acceptable for projects
 680        such as the Linux Kernel, it might be excessive for other projects.
 681        With this variable, it becomes possible to tell
 682        gitlink:git-tar-tree[1] to apply a specific umask to the modes above.
 683        The special value "user" indicates that the user's current umask will
 684        be used. This should be enough for most projects, as it will lead to
 685        the same permissions as gitlink:git-checkout[1] would use. The default
 686        value remains 0, which means world read-write.
 687
 688user.email::
 689        Your email address to be recorded in any newly created commits.
 690        Can be overridden by the 'GIT_AUTHOR_EMAIL', 'GIT_COMMITTER_EMAIL', and
 691        'EMAIL' environment variables.  See gitlink:git-commit-tree[1].
 692
 693user.name::
 694        Your full name to be recorded in any newly created commits.
 695        Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
 696        environment variables.  See gitlink:git-commit-tree[1].
 697
 698user.signingkey::
 699        If gitlink:git-tag[1] is not selecting the key you want it to
 700        automatically when creating a signed tag, you can override the
 701        default selection with this variable.  This option is passed
 702        unchanged to gpg's --local-user parameter, so you may specify a key
 703        using any method that gpg supports.
 704
 705whatchanged.difftree::
 706        The default gitlink:git-diff-tree[1] arguments to be used
 707        for gitlink:git-whatchanged[1].
 708
 709imap::
 710        The configuration variables in the 'imap' section are described
 711        in gitlink:git-imap-send[1].
 712
 713receive.unpackLimit::
 714        If the number of objects received in a push is below this
 715        limit then the objects will be unpacked into loose object
 716        files. However if the number of received objects equals or
 717        exceeds this limit then the received pack will be stored as
 718        a pack, after adding any missing delta bases.  Storing the
 719        pack from a push can make the push operation complete faster,
 720        especially on slow filesystems.
 721
 722receive.denyNonFastForwards::
 723        If set to true, git-receive-pack will deny a ref update which is
 724        not a fast forward. Use this to prevent such an update via a push,
 725        even if that push is forced. This configuration variable is
 726        set when initializing a shared repository.
 727
 728transfer.unpackLimit::
 729        When `fetch.unpackLimit` or `receive.unpackLimit` are
 730        not set, the value of this variable is used instead.
