6 Append ref names and object names of fetched refs to the
7 existing contents of `.git/FETCH_HEAD`. Without this
8 option old data in `.git/FETCH_HEAD` will be overwritten.
11 Use an atomic transaction to update local refs. Either all refs are
12 updated, or on error, no refs are updated.
15 Limit fetching to the specified number of commits from the tip of
16 each remote branch history. If fetching to a 'shallow' repository
17 created by `git clone` with `--depth=<depth>` option (see
18 linkgit:git-clone[1]), deepen or shorten the history to the specified
19 number of commits. Tags for the deepened commits are not fetched.
22 Similar to --depth, except it specifies the number of commits
23 from the current shallow boundary instead of from the tip of
24 each remote branch history.
26 --shallow-since=<date>::
27 Deepen or shorten the history of a shallow repository to
28 include all reachable commits after <date>.
30 --shallow-exclude=<revision>::
31 Deepen or shorten the history of a shallow repository to
32 exclude commits reachable from a specified remote branch or tag.
33 This option can be specified multiple times.
36 If the source repository is complete, convert a shallow
37 repository to a complete one, removing all the limitations
38 imposed by shallow repositories.
40 If the source repository is shallow, fetch as much as possible so that
41 the current repository has the same history as the source repository.
44 By default when fetching from a shallow repository,
45 `git fetch` refuses refs that require updating
46 .git/shallow. This option updates .git/shallow and accept such
49 --negotiation-tip=<commit|glob>::
50 By default, Git will report, to the server, commits reachable
51 from all local refs to find common commits in an attempt to
52 reduce the size of the to-be-received packfile. If specified,
53 Git will only report commits reachable from the given tips.
54 This is useful to speed up fetches when the user knows which
55 local ref is likely to have commits in common with the
56 upstream ref being fetched.
58 This option may be specified more than once; if so, Git will report
59 commits reachable from any of the given commits.
61 The argument to this option may be a glob on ref names, a ref, or the (possibly
62 abbreviated) SHA-1 of a commit. Specifying a glob is equivalent to specifying
63 this option multiple times, one for each matching ref name.
65 See also the `fetch.negotiationAlgorithm` and `push.negotiate`
66 configuration variables documented in linkgit:git-config[1], and the
67 `--negotiate-only` option below.
70 Do not fetch anything from the server, and instead print the
71 ancestors of the provided `--negotiation-tip=*` arguments,
72 which we have in common with the server.
74 This is incompatible with `--recurse-submodules=[yes|on-demand]`.
75 Internally this is used to implement the `push.negotiate` option, see
76 linkgit:git-config[1].
79 Show what would be done, without making any changes.
82 --[no-]write-fetch-head::
83 Write the list of remote refs fetched in the `FETCH_HEAD`
84 file directly under `$GIT_DIR`. This is the default.
85 Passing `--no-write-fetch-head` from the command line tells
86 Git not to write the file. Under `--dry-run` option, the
87 file is never written.
92 When 'git fetch' is used with `<src>:<dst>` refspec it may
93 refuse to update the local branch as discussed
95 in the `<refspec>` part of the linkgit:git-fetch[1]
99 in the `<refspec>` part below.
101 This option overrides that check.
105 Keep downloaded pack.
109 Allow several <repository> and <group> arguments to be
110 specified. No <refspec>s may be specified.
112 --[no-]auto-maintenance::
114 Run `git maintenance run --auto` at the end to perform automatic
115 repository maintenance if needed. (`--[no-]auto-gc` is a synonym.)
116 This is enabled by default.
118 --[no-]write-commit-graph::
119 Write a commit-graph after fetching. This overrides the config
120 setting `fetch.writeCommitGraph`.
124 Modify the configured refspec to place all refs into the
125 `refs/prefetch/` namespace. See the `prefetch` task in
126 linkgit:git-maintenance[1].
130 Before fetching, remove any remote-tracking references that no
131 longer exist on the remote. Tags are not subject to pruning
132 if they are fetched only because of the default tag
133 auto-following or due to a --tags option. However, if tags
134 are fetched due to an explicit refspec (either on the command
135 line or in the remote configuration, for example if the remote
136 was cloned with the --mirror option), then they are also
137 subject to pruning. Supplying `--prune-tags` is a shorthand for
138 providing the tag refspec.
141 See the PRUNING section below for more details.
145 Before fetching, remove any local tags that no longer exist on
146 the remote if `--prune` is enabled. This option should be used
147 more carefully, unlike `--prune` it will remove any local
148 references (local tags) that have been created. This option is
149 a shorthand for providing the explicit tag refspec along with
150 `--prune`, see the discussion about that in its documentation.
152 See the PRUNING section below for more details.
160 By default, tags that point at objects that are downloaded
161 from the remote repository are fetched and stored locally.
162 This option disables this automatic tag following. The default
163 behavior for a remote may be specified with the remote.<name>.tagOpt
164 setting. See linkgit:git-config[1].
168 Instead of negotiating with the server to avoid transferring commits and
169 associated objects that are already present locally, this option fetches
170 all objects as a fresh clone would. Use this to reapply a partial clone
171 filter from configuration or using `--filter=` when the filter
172 definition has changed. Automatic post-fetch maintenance will perform
173 object database pack consolidation to remove any duplicate objects.
177 When fetching refs listed on the command line, use the
178 specified refspec (can be given more than once) to map the
179 refs to remote-tracking branches, instead of the values of
180 `remote.*.fetch` configuration variables for the remote
181 repository. Providing an empty `<refspec>` to the
182 `--refmap` option causes Git to ignore the configured
183 refspecs and rely entirely on the refspecs supplied as
184 command-line arguments. See section on "Configured Remote-tracking
185 Branches" for details.
189 Fetch all tags from the remote (i.e., fetch remote tags
190 `refs/tags/*` into local tags with the same name), in addition
191 to whatever else would otherwise be fetched. Using this
192 option alone does not subject tags to pruning, even if --prune
193 is used (though tags may be pruned anyway if they are also the
194 destination of an explicit refspec; see `--prune`).
197 --recurse-submodules[=yes|on-demand|no]::
198 This option controls if and under what conditions new commits of
199 submodules should be fetched too. When recursing through submodules,
200 `git fetch` always attempts to fetch "changed" submodules, that is, a
201 submodule that has commits that are referenced by a newly fetched
202 superproject commit but are missing in the local submodule clone. A
203 changed submodule can be fetched as long as it is present locally e.g.
204 in `$GIT_DIR/modules/` (see linkgit:gitsubmodules[7]); if the upstream
205 adds a new submodule, that submodule cannot be fetched until it is
206 cloned e.g. by `git submodule update`.
208 When set to 'on-demand', only changed submodules are fetched. When set
209 to 'yes', all populated submodules are fetched and submodules that are
210 both unpopulated and changed are fetched. When set to 'no', submodules
213 When unspecified, this uses the value of `fetch.recurseSubmodules` if it
214 is set (see linkgit:git-config[1]), defaulting to 'on-demand' if unset.
215 When this option is used without any value, it defaults to 'yes'.
220 Number of parallel children to be used for all forms of fetching.
222 If the `--multiple` option was specified, the different remotes will be fetched
223 in parallel. If multiple submodules are fetched, they will be fetched in
224 parallel. To control them independently, use the config settings
225 `fetch.parallel` and `submodule.fetchJobs` (see linkgit:git-config[1]).
227 Typically, parallel recursive and multi-remote fetches will be faster. By
228 default fetches are performed sequentially, not in parallel.
231 --no-recurse-submodules::
232 Disable recursive fetching of submodules (this has the same effect as
233 using the `--recurse-submodules=no` option).
237 If the remote is fetched successfully, add upstream
238 (tracking) reference, used by argument-less
239 linkgit:git-pull[1] and other commands. For more information,
240 see `branch.<name>.merge` and `branch.<name>.remote` in
241 linkgit:git-config[1].
244 --submodule-prefix=<path>::
245 Prepend <path> to paths printed in informative messages
246 such as "Fetching submodule foo". This option is used
247 internally when recursing over submodules.
249 --recurse-submodules-default=[yes|on-demand]::
250 This option is used internally to temporarily provide a
251 non-negative default value for the --recurse-submodules
252 option. All other methods of configuring fetch's submodule
253 recursion (such as settings in linkgit:gitmodules[5] and
254 linkgit:git-config[1]) override this option, as does
255 specifying --[no-]recurse-submodules directly.
259 By default 'git fetch' refuses to update the head which
260 corresponds to the current branch. This flag disables the
261 check. This is purely for the internal use for 'git pull'
262 to communicate with 'git fetch', and unless you are
263 implementing your own Porcelain you are not supposed to
267 --upload-pack <upload-pack>::
268 When given, and the repository to fetch from is handled
269 by 'git fetch-pack', `--exec=<upload-pack>` is passed to
270 the command to specify non-default path for the command
271 run on the other end.
276 Pass --quiet to git-fetch-pack and silence any other internally
277 used git commands. Progress is not reported to the standard error
286 Progress status is reported on the standard error stream
287 by default when it is attached to a terminal, unless -q
288 is specified. This flag forces progress status even if the
289 standard error stream is not directed to a terminal.
292 --server-option=<option>::
293 Transmit the given string to the server when communicating using
294 protocol version 2. The given string must not contain a NUL or LF
295 character. The server's handling of server options, including
296 unknown ones, is server-specific.
297 When multiple `--server-option=<option>` are given, they are all
298 sent to the other side in the order listed on the command line.
300 --show-forced-updates::
301 By default, git checks if a branch is force-updated during
302 fetch. This can be disabled through fetch.showForcedUpdates, but
303 the --show-forced-updates option guarantees this check occurs.
304 See linkgit:git-config[1].
306 --no-show-forced-updates::
307 By default, git checks if a branch is force-updated during
308 fetch. Pass --no-show-forced-updates or set fetch.showForcedUpdates
309 to false to skip this check for performance reasons. If used during
310 'git-pull' the --ff-only option will still check for forced updates
311 before attempting a fast-forward update. See linkgit:git-config[1].
