NAME

6       git-fetch - Download objects and refs from another repository
7

SYNOPSIS

9       git fetch [<options>] [<repository> [<refspec>...]]
10       git fetch [<options>] <group>
11       git fetch --multiple [<options>] [(<repository> | <group>)...]
12       git fetch --all [<options>]
13

DESCRIPTION

16       Fetches named heads or tags from one or more other repositories, along
17       with the objects necessary to complete them.
18
19       The ref names and their object names of fetched refs are stored in
20       .git/FETCH_HEAD. This information is left for a later merge operation
21       done by git merge.
22
23       When <refspec> stores the fetched result in remote-tracking branches,
24       the tags that point at these branches are automatically followed. This
25       is done by first fetching from the remote using the given <refspec>s,
26       and if the repository has objects that are pointed by remote tags that
27       it does not yet have, then fetch those missing tags. If the other end
28       has tags that point at branches you are not interested in, you will not
29       get them.
30
31       git fetch can fetch from either a single named repository, or from
32       several repositories at once if <group> is given and there is a
33       remotes.<group> entry in the configuration file. (See git-config(1)).
34

OPTIONS

36       --all
37           Fetch all remotes.
38
39       -a, --append
40           Append ref names and object names of fetched refs to the existing
41           contents of .git/FETCH_HEAD. Without this option old data in
42           .git/FETCH_HEAD will be overwritten.
43
44       --depth=<depth>
45           Deepen or shorten the history of a shallow repository created by
46           git clone with --depth=<depth> option (see git-clone(1)) to the
47           specified number of commits from the tip of each remote branch
48           history. Tags for the deepened commits are not fetched.
49
50       --unshallow
51           Convert a shallow repository to a complete one, removing all the
52           limitations imposed by shallow repositories.
53
54       --dry-run
55           Show what would be done, without making any changes.
56
57       -f, --force
58           When git fetch is used with <rbranch>:<lbranch> refspec, it refuses
59           to update the local branch <lbranch> unless the remote branch
60           <rbranch> it fetches is a descendant of <lbranch>. This option
61           overrides that check.
62
63       -k, --keep
64           Keep downloaded pack.
65
66       --multiple
67           Allow several <repository> and <group> arguments to be specified.
68           No <refspec>s may be specified.
69
70       -p, --prune
71           After fetching, remove any remote-tracking branches which no longer
72           exist on the remote.
73
74       -n, --no-tags
75           By default, tags that point at objects that are downloaded from the
76           remote repository are fetched and stored locally. This option
77           disables this automatic tag following. The default behavior for a
78           remote may be specified with the remote.<name>.tagopt setting. See
79           git-config(1).
80
81       -t, --tags
82           This is a short-hand for giving "refs/tags/:refs/tags/" refspec
83           from the command line, to ask all tags to be fetched and stored
84           locally. Because this acts as an explicit refspec, the default
85           refspecs (configured with the remote.$name.fetch variable) are
86           overridden and not used.
87
88       --recurse-submodules[=yes|on-demand|no]
89           This option controls if and under what conditions new commits of
90           populated submodules should be fetched too. It can be used as a
91           boolean option to completely disable recursion when set to no or to
92           unconditionally recurse into all populated submodules when set to
93           yes, which is the default when this option is used without any
94           value. Use on-demand to only recurse into a populated submodule
95           when the superproject retrieves a commit that updates the
96           submodule’s reference to a commit that isn’t already in the local
97           submodule clone.
98
99       --no-recurse-submodules
100           Disable recursive fetching of submodules (this has the same effect
101           as using the --recurse-submodules=no option).
102
103       --submodule-prefix=<path>
104           Prepend <path> to paths printed in informative messages such as
105           "Fetching submodule foo". This option is used internally when
106           recursing over submodules.
107
108       --recurse-submodules-default=[yes|on-demand]
109           This option is used internally to temporarily provide a
110           non-negative default value for the --recurse-submodules option. All
111           other methods of configuring fetch’s submodule recursion (such as
112           settings in gitmodules(5) and git-config(1)) override this option,
113           as does specifying --[no-]recurse-submodules directly.
114
115       -u, --update-head-ok
116           By default git fetch refuses to update the head which corresponds
117           to the current branch. This flag disables the check. This is purely
118           for the internal use for git pull to communicate with git fetch,
119           and unless you are implementing your own Porcelain you are not
120           supposed to use it.
121
122       --upload-pack <upload-pack>
123           When given, and the repository to fetch from is handled by git
124           fetch-pack, --exec=<upload-pack> is passed to the command to
125           specify non-default path for the command run on the other end.
126
127       -q, --quiet
128           Pass --quiet to git-fetch-pack and silence any other internally
129           used git commands. Progress is not reported to the standard error
130           stream.
131
132       -v, --verbose
133           Be verbose.
134
135       --progress
136           Progress status is reported on the standard error stream by default
137           when it is attached to a terminal, unless -q is specified. This
138           flag forces progress status even if the standard error stream is
139           not directed to a terminal.
140
141       <repository>
142           The "remote" repository that is the source of a fetch or pull
143           operation. This parameter can be either a URL (see the section GIT
144           URLS below) or the name of a remote (see the section REMOTES
145           below).
146
147       <group>
148           A name referring to a list of repositories as the value of
149           remotes.<group> in the configuration file. (See git-config(1)).
150
151       <refspec>
152           The format of a <refspec> parameter is an optional plus +, followed
153           by the source ref <src>, followed by a colon :, followed by the
154           destination ref <dst>.
155
156           The remote ref that matches <src> is fetched, and if <dst> is not
157           empty string, the local ref that matches it is fast-forwarded using
158           <src>. If the optional plus + is used, the local ref is updated
159           even if it does not result in a fast-forward update.
160
161               Note
162               If the remote branch from which you want to pull is modified in
163               non-linear ways such as being rewound and rebased frequently,
164               then a pull will attempt a merge with an older version of
165               itself, likely conflict, and fail. It is under these conditions
166               that you would want to use the + sign to indicate
167               non-fast-forward updates will be needed. There is currently no
168               easy way to determine or declare that a branch will be made
169               available in a repository with this behavior; the pulling user
170               simply must know this is the expected usage pattern for a
171               branch.
172
173               Note
174               You never do your own development on branches that appear on
175               the right hand side of a <refspec> colon on Pull: lines; they
176               are to be updated by git fetch. If you intend to do development
177               derived from a remote branch B, have a Pull: line to track it
178               (i.e.  Pull: B:remote-B), and have a separate branch my-B to do
179               your development on top of it. The latter is created by git
180               branch my-B remote-B (or its equivalent git checkout -b my-B
181               remote-B). Run git fetch to keep track of the progress of the
182               remote side, and when you see something new on the remote
183               branch, merge it into your development branch with git pull .
184               remote-B, while you are on my-B branch.
185
186               Note
187               There is a difference between listing multiple <refspec>
188               directly on git pull command line and having multiple Pull:
189               <refspec> lines for a <repository> and running git pull command
190               without any explicit <refspec> parameters. <refspec> listed
191               explicitly on the command line are always merged into the
192               current branch after fetching. In other words, if you list more
193               than one remote refs, you would be making an Octopus. While git
194               pull run without any explicit <refspec> parameter takes default
195               <refspec>s from Pull: lines, it merges only the first <refspec>
196               found into the current branch, after fetching all the remote
197               refs. This is because making an Octopus from remote refs is
198               rarely done, while keeping track of multiple remote heads in
199               one-go by fetching more than one is often useful.
200           Some short-cut notations are also supported.
201
202           ·   tag <tag> means the same as refs/tags/<tag>:refs/tags/<tag>; it
203               requests fetching everything up to the given tag.
204
205           ·   A parameter <ref> without a colon is equivalent to <ref>: when
206               pulling/fetching, so it merges <ref> into the current branch
207               without storing the remote branch anywhere locally
208

GIT URLS

210       In general, URLs contain information about the transport protocol, the
211       address of the remote server, and the path to the repository. Depending
212       on the transport protocol, some of this information may be absent.
213
214       Git supports ssh, git, http, and https protocols (in addition, ftp, and
215       ftps can be used for fetching and rsync can be used for fetching and
216       pushing, but these are inefficient and deprecated; do not use them).
217
218       The following syntaxes may be used with them:
219
220       ·   ssh://[user@]host.xz[:port]/path/to/repo.git/
221
222       ·   git://host.xz[:port]/path/to/repo.git/
223
224       ·   http[s]://host.xz[:port]/path/to/repo.git/
225
226       ·   ftp[s]://host.xz[:port]/path/to/repo.git/
227
228       ·   rsync://host.xz/path/to/repo.git/
229
230       An alternative scp-like syntax may also be used with the ssh protocol:
231
232       ·   [user@]host.xz:path/to/repo.git/
233
234       The ssh and git protocols additionally support ~username expansion:
235
236       ·   ssh://[user@]host.xz[:port]/~[user]/path/to/repo.git/
237
238       ·   git://host.xz[:port]/~[user]/path/to/repo.git/
239
240       ·   [user@]host.xz:/~[user]/path/to/repo.git/
241
242       For local repositories, also supported by Git natively, the following
243       syntaxes may be used:
244
245       ·   /path/to/repo.git/
246
247       ·   file:///path/to/repo.git/
248
249       These two syntaxes are mostly equivalent, except when cloning, when the
250       former implies --local option. See git-clone(1) for details.
251
252       When Git doesn’t know how to handle a certain transport protocol, it
253       attempts to use the remote-<transport> remote helper, if one exists. To
254       explicitly request a remote helper, the following syntax may be used:
255
256       ·   <transport>::<address>
257
258       where <address> may be a path, a server and path, or an arbitrary
259       URL-like string recognized by the specific remote helper being invoked.
260       See gitremote-helpers(1) for details.
261
262       If there are a large number of similarly-named remote repositories and
263       you want to use a different format for them (such that the URLs you use
264       will be rewritten into URLs that work), you can create a configuration
265       section of the form:
266
267                   [url "<actual url base>"]
268                           insteadOf = <other url base>
269
270
271       For example, with this:
272
273                   [url "git://git.host.xz/"]
274                           insteadOf = host.xz:/path/to/
275                           insteadOf = work:
276
277
278       a URL like "work:repo.git" or like "host.xz:/path/to/repo.git" will be
279       rewritten in any context that takes a URL to be
280       "git://git.host.xz/repo.git".
281
282       If you want to rewrite URLs for push only, you can create a
283       configuration section of the form:
284
285                   [url "<actual url base>"]
286                           pushInsteadOf = <other url base>
287
288
289       For example, with this:
290
291                   [url "ssh://example.org/"]
292                           pushInsteadOf = git://example.org/
293
294
295       a URL like "git://example.org/path/to/repo.git" will be rewritten to
296       "ssh://example.org/path/to/repo.git" for pushes, but pulls will still
297       use the original URL.
298

REMOTES

300       The name of one of the following can be used instead of a URL as
301       <repository> argument:
302
303       ·   a remote in the Git configuration file: $GIT_DIR/config,
304
305       ·   a file in the $GIT_DIR/remotes directory, or
306
307       ·   a file in the $GIT_DIR/branches directory.
308
309       All of these also allow you to omit the refspec from the command line
310       because they each contain a refspec which git will use by default.
311
312   Named remote in configuration file
313       You can choose to provide the name of a remote which you had previously
314       configured using git-remote(1), git-config(1) or even by a manual edit
315       to the $GIT_DIR/config file. The URL of this remote will be used to
316       access the repository. The refspec of this remote will be used by
317       default when you do not provide a refspec on the command line. The
318       entry in the config file would appear like this:
319
320                   [remote "<name>"]
321                           url = <url>
322                           pushurl = <pushurl>
323                           push = <refspec>
324                           fetch = <refspec>
325
326
327       The <pushurl> is used for pushes only. It is optional and defaults to
328       <url>.
329
330   Named file in $GIT_DIR/remotes
331       You can choose to provide the name of a file in $GIT_DIR/remotes. The
332       URL in this file will be used to access the repository. The refspec in
333       this file will be used as default when you do not provide a refspec on
334       the command line. This file should have the following format:
335
336                   URL: one of the above URL format
337                   Push: <refspec>
338                   Pull: <refspec>
339
340
341       Push: lines are used by git push and Pull: lines are used by git pull
342       and git fetch. Multiple Push: and Pull: lines may be specified for
343       additional branch mappings.
344
345   Named file in $GIT_DIR/branches
346       You can choose to provide the name of a file in $GIT_DIR/branches. The
347       URL in this file will be used to access the repository. This file
348       should have the following format:
349
350                   <url>#<head>
351
352
353       <url> is required; #<head> is optional.
354
355       Depending on the operation, git will use one of the following refspecs,
356       if you don’t provide one on the command line. <branch> is the name of
357       this file in $GIT_DIR/branches and <head> defaults to master.
358
359       git fetch uses:
360
361                   refs/heads/<head>:refs/heads/<branch>
362
363
364       git push uses:
365
366                   HEAD:refs/heads/<head>
367
368

EXAMPLES

370       ·   Update the remote-tracking branches:
371
372               $ git fetch origin
373
374           The above command copies all branches from the remote refs/heads/
375           namespace and stores them to the local refs/remotes/origin/
376           namespace, unless the branch.<name>.fetch option is used to specify
377           a non-default refspec.
378
379       ·   Using refspecs explicitly:
380
381               $ git fetch origin +pu:pu maint:tmp
382
383           This updates (or creates, as necessary) branches pu and tmp in the
384           local repository by fetching from the branches (respectively) pu
385           and maint from the remote repository.
386
387           The pu branch will be updated even if it is does not fast-forward,
388           because it is prefixed with a plus sign; tmp will not be.

BUGS

391       Using --recurse-submodules can only fetch new commits in already
392       checked out submodules right now. When e.g. upstream added a new
393       submodule in the just fetched commits of the superproject the submodule
394       itself can not be fetched, making it impossible to check out that
395       submodule later without having to do a fetch again. This is expected to
396       be fixed in a future Git version.
