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

34 Variables
35 ~~~~~~~~~
36
37 Note that this list is non-comprehensive and not necessarily complete.
38 For command-specific variables, you will find a more detailed description
39 in the appropriate manual page. You will find a description of non-core
40 porcelain configuration variables in the respective porcelain documentation.
41
42 core.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
47 core.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.
55 +
56 Can be overridden by the 'GIT_PROXY_COMMAND' environment variable
57 (which always applies universally, without the special "for"
58 handling).
59
60 core.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
67 core.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.
72
73 core.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
81 core.repositoryFormatVersion::
82 Internal variable identifying the repository format and layout
83 version.
84
85 core.sharedRepository::
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.
92
93 core.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
97 core.compression::
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
103 core.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
109 alias.*::
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
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.
117
118 apply.whitespace::
119 Tells `git-apply` how to handle whitespaces, in the same way
120 as the '--whitespace' option. See gitlink:git-apply[1].
121
122 branch.<name>.remote::
123 When in branch <name>, it tells `git fetch` which remote to fetch.
124
125 branch.<name>.merge::
126 When in branch <name>, it tells `git fetch` the default remote branch
127 to be merged.
128
129 pager.color::
130 A boolean to enable/disable colored output when the pager is in
131 use (default is true).
132
133 diff.color::
134 When true (or `always`), always use colors in patch.
135 When false (or `never`), never. When set to `auto`, use
136 colors only when the output is to the terminal.
137
138 diff.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
149 diff.renameLimit::
150 The number of files to consider when performing the copy/rename
151 detection; equivalent to the git diff option '-l'.
152
153 diff.renames::
154 Tells git to detect renames. If set to any boolean value, it
155 will enable basic rename detection. If set to "copies" or
156 "copy", it will detect copies, as well.
157
158 format.headers::
159 Additional email headers to include in a patch to be submitted
160 by mail. See gitlink:git-format-patch[1].
161
162 gitcvs.enabled::
163 Whether the cvs pserver interface is enabled for this repository.
164 See gitlink:git-cvsserver[1].
165
166 gitcvs.logfile::
167 Path to a log file where the cvs pserver interface well... logs
168 various stuff. See gitlink:git-cvsserver[1].
169
170 http.sslVerify::
171 Whether to verify the SSL certificate when fetching or pushing
172 over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
173 variable.
174
175 http.sslCert::
176 File containing the SSL certificate when fetching or pushing
177 over HTTPS. Can be overridden by the 'GIT_SSL_CERT' environment
178 variable.
179
180 http.sslKey::
181 File containing the SSL private key when fetching or pushing
182 over HTTPS. Can be overridden by the 'GIT_SSL_KEY' environment
183 variable.
184
185 http.sslCAInfo::
186 File containing the certificates to verify the peer with when
187 fetching or pushing over HTTPS. Can be overridden by the
188 'GIT_SSL_CAINFO' environment variable.
189
190 http.sslCAPath::
191 Path containing files with the CA certificates to verify the peer
192 with when fetching or pushing over HTTPS. Can be overridden
193 by the 'GIT_SSL_CAPATH' environment variable.
194
195 http.maxRequests::
196 How many HTTP requests to launch in parallel. Can be overridden
197 by the 'GIT_HTTP_MAX_REQUESTS' environment variable. Default is 5.
198
199 http.lowSpeedLimit, http.lowSpeedTime::
200 If the HTTP transfer speed is less than 'http.lowSpeedLimit'
201 for longer than 'http.lowSpeedTime' seconds, the transfer is aborted.
202 Can be overridden by the 'GIT_HTTP_LOW_SPEED_LIMIT' and
203 'GIT_HTTP_LOW_SPEED_TIME' environment variables.
204
205 http.noEPSV::
206 A boolean which disables using of EPSV ftp command by curl.
207 This can helpful with some "poor" ftp servers which doesn't
208 support EPSV mode. Can be overridden by the 'GIT_CURL_FTP_NO_EPSV'
209 environment variable. Default is false (curl will use EPSV).
210
211 i18n.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
218 merge.summary::
219 Whether to include summaries of merged commits in newly created
220 merge commit messages. False by default.
221
222 pack.window::
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
226 pull.octopus::
227 The default merge strategy to use when pulling multiple branches
228 at once.
229
230 pull.twohead::
231 The default merge strategy to use when pulling a single branch.
232
233 show.difftree::
234 The default gitlink:git-diff-tree[1] arguments to be used
235 for gitlink:git-show[1].
236
237 showbranch.default::
238 The default set of branches for gitlink:git-show-branch[1].
239 See gitlink:git-show-branch[1].
240
241 status.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
247 status.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
255 tar.umask::
256 By default, gitlink:git-tar-tree[1] sets file and directories modes
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
260 gitlink:git-tar-tree[1] to apply a specific umask to the modes above.
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
263 the same permissions as gitlink:git-checkout[1] would use. The default
264 value remains 0, which means world read-write.
265
266 user.email::
267 Your email address to be recorded in any newly created commits.
268 Can be overridden by the 'GIT_AUTHOR_EMAIL' and 'GIT_COMMITTER_EMAIL'
269 environment variables. See gitlink:git-commit-tree[1].
270
271 user.name::
272 Your full name to be recorded in any newly created commits.
273 Can be overridden by the 'GIT_AUTHOR_NAME' and 'GIT_COMMITTER_NAME'
274 environment variables. See gitlink:git-commit-tree[1].
275
276 whatchanged.difftree::
277 The default gitlink:git-diff-tree[1] arguments to be used
278 for gitlink:git-whatchanged[1].
279
280 imap::
281 The configuration variables in the 'imap' section are described
282 in gitlink:git-imap-send[1].
283
284 receive.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.
