1CONFIGURATION FILE
2------------------
3
4The git configuration file contains a number of variables that affect
5ea5621f
JH
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
32043c9f
JS
8fallback values for `.git/config` file. The file `/etc/gitconfig`
9can be used to store system-wide defaults.
5ea5621f

11They can be used by both the git plumbing
b8936cf0 12and the porcelains. The variables are divided into sections, where
1ab661dd
PB
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.

18Syntax
19~~~~~~
20
1ab661dd 21The syntax is fairly flexible and permissive; whitespaces are mostly
e136f33b
JN
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
191453f6
JN
41Subsection names can contain any characters except newline (doublequote
42'`"`' and backslash have to be escaped as '`\"`' and '`\\`',
3dff5379 43respectively) and are case sensitive. Section header cannot span multiple
e136f33b
JN
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;
e0d10e1c 66`git-config` will ensure that the output is "true" or "false".
e136f33b
JN
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.

111For command-specific variables, you will find a more detailed description
112in the appropriate manual page. You will find a description of non-core
1ab661dd
PB
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
5cb71f82
FL
120core.autocrlf::
121 If true, makes git convert `CRLF` at the end of lines in text files to
122 `LF` when reading from the filesystem, and convert in reverse when
123 writing to the filesystem. The variable can be set to
124 'input', in which case the conversion happens only while
125 reading from the filesystem but files are written out with
126 `LF` at the end of lines. Currently, which paths to consider
127 "text" (i.e. be subjected to the autocrlf mechanism) is
128 decided purely based on the contents.
129
78a8d641
JS
130core.symlinks::
131 If false, symbolic links are checked out as small plain files that
132 contain the link text. gitlink:git-update-index[1] and
133 gitlink:git-add[1] will not change the recorded type to regular
134 file. Useful on filesystems like FAT that do not support
135 symbolic links. True by default.
136
1ab661dd
PB
137core.gitProxy::
138 A "proxy command" to execute (as 'command host port') instead
139 of establishing direct connection to the remote server when
140 using the git protocol for fetching. If the variable value is
141 in the "COMMAND for DOMAIN" format, the command is applied only
142 on hostnames ending with the specified domain string. This variable
143 may be set multiple times and is matched in the given order;
144 the first match wins.
b8936cf0
FD
145+
146Can be overridden by the 'GIT_PROXY_COMMAND' environment variable
147(which always applies universally, without the special "for"
148handling).
1ab661dd
PB
149
150core.ignoreStat::
151 The working copy files are assumed to stay unchanged until you
152 mark them otherwise manually - Git will not detect the file changes
153 by lstat() calls. This is useful on systems where those are very
154 slow, such as Microsoft Windows. See gitlink:git-update-index[1].
155 False by default.
156
9f0bb90d
JH
157core.preferSymlinkRefs::
158 Instead of the default "symref" format for HEAD
159 and other symbolic reference files, use symbolic links.
160 This is sometimes needed to work with old scripts that
161 expect HEAD to be a symbolic link.
1ab661dd 162
e4a15f40
SP
163core.bare::
164 If true this repository is assumed to be 'bare' and has no
165 working directory associated with it. If this is the case a
166 number of commands that require a working directory will be
167 disabled, such as gitlink:git-add[1] or gitlink:git-merge[1].
168+
169This setting is automatically guessed by gitlink:git-clone[1] or
170gitlink:git-init[1] when the repository was created. By default a
171repository that ends in "/.git" is assumed to be not bare (bare =
172false), while all other repositories are assumed to be bare (bare
173= true).
174
6de08ae6 175core.logAllRefUpdates::
4057deb5
JH
176 Updates to a ref <ref> is logged to the file
177 "$GIT_DIR/logs/<ref>", by appending the new and old
178 SHA1, the date/time and the reason of the update, but
179 only when the file exists. If this configuration
180 variable is set to true, missing "$GIT_DIR/logs/<ref>"
181 file is automatically created for branch heads.
a862f97e
JH
182+
183This information can be used to determine what commit
184was the tip of a branch "2 days ago".
185+
186This value is true by default in a repository that has
187a working directory associated with it, and false by
188default in a bare repository.
6de08ae6 189
1ab661dd
PB
190core.repositoryFormatVersion::
191 Internal variable identifying the repository format and layout
192 version.
193
194core.sharedRepository::
d5dc6a76
JF
195 When 'group' (or 'true'), the repository is made shareable between
196 several users in a group (making sure all the files and objects are
197 group-writable). When 'all' (or 'world' or 'everybody'), the
198 repository will be readable by all users, additionally to being
199 group-shareable. When 'umask' (or 'false'), git will use permissions
5c94f87e 200 reported by umask(2). See gitlink:git-init[1]. False by default.
1ab661dd
PB
201
202core.warnAmbiguousRefs::
203 If true, git will warn you if the ref name you passed it is ambiguous
204 and might match multiple refs in the .git/refs/ tree. True by default.
205
3d3e95af 206core.compression::
12f6c308
JBH
207 An integer -1..9, indicating the compression level for objects that
208 are not in a pack file. -1 is the zlib and git default. 0 means no
209 compression, and 1..9 are various speed/size tradeoffs, 9 being
210 slowest.
211
93821bd9 212core.legacyheaders::
bdd69c2f
SB
213 A boolean which
214 changes the format of loose objects so that they are more
215 efficient to pack and to send out of the repository over git
216 native protocol, since v1.4.2. However, loose objects
217 written in the new format cannot be read by git older than
218 that version; people fetching from your repository using
219 older versions of git over dumb transports (e.g. http)
220 will also be affected.
221+
222To let git use the new loose object format, you have to
223set core.legacyheaders to false.
93821bd9 224
60bb8b14
SP
225core.packedGitWindowSize::
226 Number of bytes of a pack file to map into memory in a
227 single mapping operation. Larger window sizes may allow
228 your system to process a smaller number of large pack files
229 more quickly. Smaller window sizes will negatively affect
eb92242f 230 performance due to increased calls to the operating system's
60bb8b14 231 memory manager, but may improve performance when accessing
22bac0ea
SP
232 a large number of large pack files.
233+
234Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
235MiB on 32 bit platforms and 1 GiB on 64 bit platforms. This should
236be reasonable for all users/operating systems. You probably do
237not need to adjust this value.
eb92242f
SP
238+
239Common unit suffixes of 'k', 'm', or 'g' are supported.
60bb8b14 240
77ccc5bb
SP
241core.packedGitLimit::
242 Maximum number of bytes to map simultaneously into memory
243 from pack files. If Git needs to access more than this many
244 bytes at once to complete an operation it will unmap existing
245 regions to reclaim virtual address space within the process.
22bac0ea
SP
246+
247Default is 256 MiB on 32 bit platforms and 8 GiB on 64 bit platforms.
248This should be reasonable for all users/operating systems, except on
249the largest projects. You probably do not need to adjust this value.

251Common unit suffixes of 'k', 'm', or 'g' are supported.
77ccc5bb 252
18bdec11
SP
253core.deltaBaseCacheLimit::
254 Maximum number of bytes to reserve for caching base objects
255 that multiple deltafied objects reference. By storing the
256 entire decompressed base objects in a cache Git is able
257 to avoid unpacking and decompressing frequently used base
258 objects multiple times.
259+
260Default is 16 MiB on all platforms. This should be reasonable
261for all users/operating systems, except on the largest projects.
262You probably do not need to adjust this value.
263+
264Common unit suffixes of 'k', 'm', or 'g' are supported.
265
4514ad4f
PB
266alias.*::
267 Command aliases for the gitlink:git[1] command wrapper - e.g.
268 after defining "alias.last = cat-file commit HEAD", the invocation
269 "git last" is equivalent to "git cat-file commit HEAD". To avoid
99b41c84
PB
270 confusion and troubles with script usage, aliases that
271 hide existing git commands are ignored. Arguments are split by
272 spaces, the usual shell quoting and escaping is supported.
273 quote pair and a backslash can be used to quote them.
4514ad4f 274
dfd42a3c
TT
275 If the alias expansion is prefixed with an exclamation point,
276 it will be treated as a shell command. For example, defining
277 "alias.new = !gitk --all --not ORIG_HEAD", the invocation
278 "git new" is equivalent to running the shell command
279 "gitk --all --not ORIG_HEAD".
280
1ab661dd
PB
281apply.whitespace::
282 Tells `git-apply` how to handle whitespaces, in the same way
283 as the '--whitespace' option. See gitlink:git-apply[1].
284
648ad18f
SB
285branch.<name>.remote::
286 When in branch <name>, it tells `git fetch` which remote to fetch.
62b339a5 287 If this option is not given, `git fetch` defaults to remote "origin".
648ad18f 288
5372806a 289branch.<name>.merge::
62b339a5
JW
290 When in branch <name>, it tells `git fetch` the default refspec to
291 be marked for merging in FETCH_HEAD. The value has exactly to match
292 a remote part of one of the refspecs which are fetched from the remote
293 given by "branch.<name>.remote".
294 The merge information is used by `git pull` (which at first calls
295 `git fetch`) to lookup the default branch for merging. Without
296 this option, `git pull` defaults to merge the first refspec fetched.
297 Specify multiple values to get an octopus merge.
9debc324
PB
298 If you wish to setup `git pull` so that it merges into <name> from
299 another branch in the local repository, you can point
300 branch.<name>.merge to the desired branch, and use the special setting
301 `.` (a period) for branch.<name>.remote.
5372806a 302
2122591b
JT
303clean.requireForce::
304 A boolean to make git-clean do nothing unless given -f or -n. Defaults
305 to false.
306
f3673988
BG
307color.branch::
308 A boolean to enable/disable color in the output of
309 gitlink:git-branch[1]. May be set to `true` (or `always`),
310 `false` (or `never`) or `auto`, in which case colors are used
311 only when the output is to a terminal. Defaults to false.
312
313color.branch.<slot>::
314 Use customized color for branch coloration. `<slot>` is one of
315 `current` (the current branch), `local` (a local branch),
316 `remote` (a tracking branch in refs/remotes/), `plain` (other
4f193f20
MW
317 refs).
318+
319The value for these configuration variables is a list of colors (at most
320two) and attributes (at most one), separated by spaces. The colors
321accepted are `normal`, `black`, `red`, `green`, `yellow`, `blue`,
322`magenta`, `cyan` and `white`; the attributes are `bold`, `dim`, `ul`,
323`blink` and `reverse`. The first color given is the foreground; the
324second is the background. The position of the attribute, if any,
325doesn't matter.
f3673988 326
a159ca0c 327color.diff::
b5376648
JH
328 When true (or `always`), always use colors in patch.
329 When false (or `never`), never. When set to `auto`, use
330 colors only when the output is to the terminal.
331
a159ca0c 332color.diff.<slot>::
4f193f20
MW
333 Use customized color for diff colorization. `<slot>` specifies
334 which part of the patch to use the specified color, and is one
335 of `plain` (context text), `meta` (metainformation), `frag`
336 (hunk header), `old` (removed lines), `new` (added lines),
337 `commit` (commit headers), or `whitespace` (highlighting dubious
338 whitespace). The values of these variables may be specified as
339 in color.branch.<slot>.
b5376648 340
1d77043b
JH
341color.pager::
342 A boolean to enable/disable colored output when the pager is in
343 use (default is true).
344
345color.status::
346 A boolean to enable/disable color in the output of
347 gitlink:git-status[1]. May be set to `true` (or `always`),
348 `false` (or `never`) or `auto`, in which case colors are used
349 only when the output is to a terminal. Defaults to false.
350
351color.status.<slot>::
352 Use customized color for status colorization. `<slot>` is
353 one of `header` (the header text of the status message),
82dca848
SP
354 `added` or `updated` (files which are added but not committed),
355 `changed` (files which are changed but not added in the index),
1d77043b 356 or `untracked` (files which are not tracked by git). The values of
f3673988 357 these variables may be specified as in color.branch.<slot>.
1d77043b 358
1ab661dd
PB
359diff.renameLimit::
360 The number of files to consider when performing the copy/rename
361 detection; equivalent to the git diff option '-l'.
362
b68ea12e
EW
363diff.renames::
364 Tells git to detect renames. If set to any boolean value, it
365 will enable basic rename detection. If set to "copies" or
366 "copy", it will detect copies, as well.
367
af7cf268
JH
368fetch.unpackLimit::
369 If the number of objects fetched over the git native
370 transfer is below this
371 limit, then the objects will be unpacked into loose object
372 files. However if the number of received objects equals or
373 exceeds this limit then the received pack will be stored as
374 a pack, after adding any missing delta bases. Storing the
375 pack from a push can make the push operation complete faster,
376 especially on slow filesystems.
377
1ab661dd
PB
378format.headers::
379 Additional email headers to include in a patch to be submitted
380 by mail. See gitlink:git-format-patch[1].
381
78cb59c8
JS
382format.suffix::
383 The default for format-patch is to output files with the suffix
384 `.patch`. Use this variable to change that suffix (make sure to
385 include the dot if you want it).
1ab661dd 386
c2120e5e
JS
387gc.packrefs::
388 `git gc` does not run `git pack-refs` in a bare repository by
389 default so that older dumb-transport clients can still fetch
390 from the repository. Setting this to `true` lets `git
391 gc` to run `git pack-refs`. Setting this to `false` tells
392 `git gc` never to run `git pack-refs`. The default setting is
393 `notbare`. Enable it only when you know you do not have to
394 support such clients. The default setting will change to `true`
395 at some stage, and setting this to `false` will continue to
396 prevent `git pack-refs` from being run from `git gc`.
397
4aec56d1
JH
398gc.reflogexpire::
399 `git reflog expire` removes reflog entries older than
400 this time; defaults to 90 days.
401
402gc.reflogexpireunreachable::
403 `git reflog expire` removes reflog entries older than
404 this time and are not reachable from the current tip;
405 defaults to 30 days.
406
48c32424
JH
407gc.rerereresolved::
408 Records of conflicted merge you resolved earlier are
409 kept for this many days when `git rerere gc` is run.
410 The default is 60 days. See gitlink:git-rerere[1].
411
412gc.rerereunresolved::
413 Records of conflicted merge you have not resolved are
414 kept for this many days when `git rerere gc` is run.
415 The default is 15 days. See gitlink:git-rerere[1].
416
1ab661dd 417gitcvs.enabled::
5007af8c 418 Whether the cvs server interface is enabled for this repository.
1ab661dd
PB
419 See gitlink:git-cvsserver[1].
420
421gitcvs.logfile::

PB
423 various stuff. See gitlink:git-cvsserver[1].
424
eabb0bfd
FL
425gitcvs.allbinary::
426 If true, all files are sent to the client in mode '-kb'. This
427 causes the client to treat all files as binary files which suppresses
428 any newline munging it otherwise might do. A work-around for the
429 fact that there is no way yet to set single files to mode '-kb'.
abbf5947 430
04752868
FL
431gitcvs.dbname::
432 Database used by git-cvsserver to cache revision information
433 derived from the git repository. The exact meaning depends on the
434 used database driver, for SQLite (which is the default driver) this
435 is a filename. Supports variable substitution (see
436 gitlink:git-cvsserver[1] for details). May not contain semicolons (`;`).
437 Default: '%Ggitcvs.%m.sqlite'
438
439gitcvs.dbdriver::
440 Used Perl DBI driver. You can specify any available driver
441 for this here, but it might not work. git-cvsserver is tested
442 with 'DBD::SQLite', reported to work with 'DBD::Pg', and
443 reported *not* to work with 'DBD::mysql'. Experimental feature.
444 May not contain double colons (`:`). Default: 'SQLite'.
eabb0bfd
FL
445 See gitlink:git-cvsserver[1].
446
04752868
FL
447gitcvs.dbuser, gitcvs.dbpass::
448 Database user and password. Only useful if setting 'gitcvs.dbdriver',
449 since SQLite has no concept of database users and/or passwords.
450 'gitcvs.dbuser' supports variable substitution (see
451 gitlink:git-cvsserver[1] for details).
452
453All gitcvs variables except for 'gitcvs.allbinary' can also specifed
454as 'gitcvs.<access_method>.<varname>' (where 'access_method' is one
455of "ext" and "pserver") to make them apply only for the given access
456method.

499i18n.commitEncoding::
500 Character encoding the commit messages are stored in; git itself
501 does not care per se, but this information is necessary e.g. when
502 importing commits from emails or in the gitk graphical history

7fe08af4 601 By default, gitlink:git-tar-tree[1] sets file and directories modes
ce1a79b6
WT
602 to 0666 or 0777. While this is both useful and acceptable for projects
603 such as the Linux Kernel, it might be excessive for other projects.
604 With this variable, it becomes possible to tell
7fe08af4 605 gitlink:git-tar-tree[1] to apply a specific umask to the modes above.
ce1a79b6
WT
606 The special value "user" indicates that the user's current umask will
607 be used. This should be enough for most projects, as it will lead to
7fe08af4 608 the same permissions as gitlink:git-checkout[1] would use. The default
ce1a79b6
WT
609 value remains 0, which means world read-write.

621user.signingkey::
622 If gitlink:git-tag[1] is not selecting the key you want it to
623 automatically when creating a signed tag, you can override the
624 default selection with this variable. This option is passed
625 unchanged to gpg's --local-user parameter, so you may specify a key

636receive.unpackLimit::
637 If the number of objects received in a push is below this
638 limit then the objects will be unpacked into loose object
639 files. However if the number of received objects equals or
640 exceeds this limit then the received pack will be stored as
641 a pack, after adding any missing delta bases. Storing the
642 pack from a push can make the push operation complete faster,
643 especially on slow filesystems.
644
645receive.denyNonFastForwards::
199a9218
JS
646 If set to true, git-receive-pack will deny a ref update which is
647 not a fast forward. Use this to prevent such an update via a push,
648 even if that push is forced. This configuration variable is
649 set when initializing a shared repository.
