1CONFIGURATION FILE
2------------------
3
4The git configuration file contains a number of variables that affect
b8936cf0
FD
5the git command's behavior. They can be used by both the git plumbing
6and the porcelains. The variables are divided into sections, where
1ab661dd
PB
7in the fully qualified variable name the variable itself is the last
8dot-separated segment and the section name is everything before the last
9dot. The variable names are case-insensitive and only alphanumeric
10characters are allowed. Some variables may appear multiple times.
11
12The syntax is fairly flexible and permissive; whitespaces are mostly
b8936cf0 13ignored. The '#' and ';' characters begin comments to the end of line,
1ab661dd
PB
14blank lines are ignored, lines containing strings enclosed in square
15brackets start sections and all the other lines are recognized
16as setting variables, in the form 'name = value'. If there is no equal
17sign on the line, the entire line is taken as 'name' and the variable
18is recognized as boolean "true". String values may be entirely or partially
19enclosed in double quotes; some variables may require special value format.

38For command-specific variables, you will find a more detailed description
39in the appropriate manual page. You will find a description of non-core
1ab661dd
PB
40porcelain configuration variables in the respective porcelain documentation.
41
42core.fileMode::
43 If false, the executable bit differences between the index and
44 the working copy are ignored; useful on broken filesystems like FAT.
45 See gitlink:git-update-index[1]. True by default.
46
47core.gitProxy::
48 A "proxy command" to execute (as 'command host port') instead
49 of establishing direct connection to the remote server when
50 using the git protocol for fetching. If the variable value is
51 in the "COMMAND for DOMAIN" format, the command is applied only
52 on hostnames ending with the specified domain string. This variable
53 may be set multiple times and is matched in the given order;
54 the first match wins.
b8936cf0
FD
55+
56Can be overridden by the 'GIT_PROXY_COMMAND' environment variable
57(which always applies universally, without the special "for"
58handling).
1ab661dd
PB
59
60core.ignoreStat::
61 The working copy files are assumed to stay unchanged until you
62 mark them otherwise manually - Git will not detect the file changes
63 by lstat() calls. This is useful on systems where those are very
64 slow, such as Microsoft Windows. See gitlink:git-update-index[1].
65 False by default.
66
9f0bb90d
JH
67core.preferSymlinkRefs::
68 Instead of the default "symref" format for HEAD
69 and other symbolic reference files, use symbolic links.
70 This is sometimes needed to work with old scripts that
71 expect HEAD to be a symbolic link.
1ab661dd 72
6de08ae6
SP
73core.logAllRefUpdates::
74 If true, `git-update-ref` will append a line to
75 "$GIT_DIR/logs/<ref>" listing the new SHA1 and the date/time
76 of the update. If the file does not exist it will be
77 created automatically. This information can be used to
78 determine what commit was the tip of a branch "2 days ago".
79 This value is false by default (no logging).
80
1ab661dd
PB
81core.repositoryFormatVersion::
82 Internal variable identifying the repository format and layout
83 version.
84
85core.sharedRepository::
d5dc6a76
JF
86 When 'group' (or 'true'), the repository is made shareable between
87 several users in a group (making sure all the files and objects are
88 group-writable). When 'all' (or 'world' or 'everybody'), the
89 repository will be readable by all users, additionally to being
90 group-shareable. When 'umask' (or 'false'), git will use permissions
91 reported by umask(2). See gitlink:git-init-db[1]. False by default.
1ab661dd
PB
92
93core.warnAmbiguousRefs::
94 If true, git will warn you if the ref name you passed it is ambiguous
95 and might match multiple refs in the .git/refs/ tree. True by default.
96
3d3e95af 97core.compression::
12f6c308
JBH
98 An integer -1..9, indicating the compression level for objects that
99 are not in a pack file. -1 is the zlib and git default. 0 means no
100 compression, and 1..9 are various speed/size tradeoffs, 9 being
101 slowest.
102
93821bd9
LT
103core.legacyheaders::
104 A boolean which enables the legacy object header format in case
105 you want to interoperate with old clients accessing the object
106 database directly (where the "http://" and "rsync://" protocols
107 count as direct access).
108
4514ad4f
PB
109alias.*::
110 Command aliases for the gitlink:git[1] command wrapper - e.g.
111 after defining "alias.last = cat-file commit HEAD", the invocation
112 "git last" is equivalent to "git cat-file commit HEAD". To avoid
99b41c84
PB
113 confusion and troubles with script usage, aliases that
114 hide existing git commands are ignored. Arguments are split by
115 spaces, the usual shell quoting and escaping is supported.
116 quote pair and a backslash can be used to quote them.
4514ad4f 117
1ab661dd
PB
118apply.whitespace::
119 Tells `git-apply` how to handle whitespaces, in the same way
120 as the '--whitespace' option. See gitlink:git-apply[1].

136 colors only when the output is to the terminal.
137
138diff.color.<slot>::
139 Use customized color for diff colorization. `<slot>`
140 specifies which part of the patch to use the specified
141 color, and is one of `plain` (context text), `meta`
142 (metainformation), `frag` (hunk header), `old` (removed
143 lines), or `new` (added lines). The value for these
144 configuration variables can be one of: `normal`, `bold`,
145 `dim`, `ul`, `blink`, `reverse`, `reset`, `black`,
146 `red`, `green`, `yellow`, `blue`, `magenta`, `cyan`, or
147 `white`.
148

209 environment variable. Default is false (curl will use EPSV).
210
1ab661dd
PB
211i18n.commitEncoding::
212 Character encoding the commit messages are stored in; git itself
213 does not care per se, but this information is necessary e.g. when
214 importing commits from emails or in the gitk graphical history
215 browser (and possibly at other places in the future or in other
216 porcelains). See e.g. gitlink:git-mailinfo[1]. Defaults to 'utf-8'.
217
218merge.summary::
219 Whether to include summaries of merged commits in newly created
220 merge commit messages. False by default.
221
4812a93a

223 The size of the window used by gitlink:git-pack-objects[1] when no
224 window size is given on the command line. Defaults to 10.
225

239 See gitlink:git-show-branch[1].
240
b982592d
JK
241status.color::
242 A boolean to enable/disable color in the output of
243 gitlink:git-status[1]. May be set to `true` (or `always`),
244 `false` (or `never`) or `auto`, in which case colors are used
245 only when the output is to a terminal. Defaults to false.
246
247status.color.<slot>::
248 Use customized color for status colorization. `<slot>` is
249 one of `header` (the header text of the status message),
250 `updated` (files which are updated but not committed),
251 `changed` (files which are changed but not updated in the index),
252 or `untracked` (files which are not tracked by git). The values of
253 these variables may be specified as in diff.color.<slot>.
254
ce1a79b6 255tar.umask::
7fe08af4 256 By default, gitlink:git-tar-tree[1] sets file and directories modes
ce1a79b6
WT
257 to 0666 or 0777. While this is both useful and acceptable for projects
258 such as the Linux Kernel, it might be excessive for other projects.
259 With this variable, it becomes possible to tell
7fe08af4 260 gitlink:git-tar-tree[1] to apply a specific umask to the modes above.
ce1a79b6
WT
261 The special value "user" indicates that the user's current umask will
262 be used. This should be enough for most projects, as it will lead to
7fe08af4 263 the same permissions as gitlink:git-checkout[1] would use. The default
ce1a79b6
WT
264 value remains 0, which means world read-write.
265
1ab661dd
PB
266user.email::
267 Your email address to be recorded in any newly created commits.
abda1ef5 268 Can be overridden by the 'GIT_AUTHOR_EMAIL' and 'GIT_COMMITTER_EMAIL'

272 Your full name to be recorded in any newly created commits.
abda1ef5 273 Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
1ab661dd
PB
274 environment variables. See gitlink:git-commit-tree[1].
275
276whatchanged.difftree::
277 The default gitlink:git-diff-tree[1] arguments to be used
278 for gitlink:git-whatchanged[1].
279
280imap::
281 The configuration variables in the 'imap' section are described
282 in gitlink:git-imap-send[1].
199a9218
JS
283
284receive.denyNonFastforwads::
285 If set to true, git-receive-pack will deny a ref update which is
286 not a fast forward. Use this to prevent such an update via a push,
287 even if that push is forced. This configuration variable is
288 set when initializing a shared repository.
