6 git-push - Update remote refs along with associated objects
12 'git-push' [--all] [--dry-run] [--tags] [--receive-pack=<git-receive-pack>]
13 [--repo=all] [-f | --force] [-v | --verbose] [<repository> <refspec>...]
18 Updates remote refs using local refs, while sending objects
19 necessary to complete the given refs.
21 You can make interesting things happen to a repository
22 every time you push into it, by setting up 'hooks' there. See
23 documentation for linkgit:git-receive-pack[1].
29 The "remote" repository that is destination of a push
30 operation. See the section <<URLS,GIT URLS>> below.
33 The canonical format of a <refspec> parameter is
34 `+?<src>:<dst>`; that is, an optional plus `+`, followed
35 by the source ref, followed by a colon `:`, followed by
38 The <src> side represents the source branch (or arbitrary
39 "SHA1 expression", such as `master~4` (four parents before the
40 tip of `master` branch); see linkgit:git-rev-parse[1]) that you
41 want to push. The <dst> side represents the destination location.
43 The local ref that matches <src> is used
44 to fast forward the remote ref that matches <dst> (or, if no <dst> was
45 specified, the same ref that <src> referred to locally). If
46 the optional leading plus `+` is used, the remote ref is updated
47 even if it does not result in a fast forward update.
49 `tag <tag>` means the same as `refs/tags/<tag>:refs/tags/<tag>`.
51 A parameter <ref> without a colon pushes the <ref> from the source
52 repository to the destination repository under the same name.
54 Pushing an empty <src> allows you to delete the <dst> ref from
55 the remote repository.
57 The special refspec `:` (or `+:` to allow non-fast forward updates)
58 directs git to push "matching" heads: for every head that exists on
59 the local side, the remote side is updated if a head of the same name
60 already exists on the remote side. This is the default operation mode
61 if no explicit refspec is found (that is neither on the command line
62 nor in any Push line of the corresponding remotes file---see below).
65 Instead of naming each ref to push, specifies that all
66 refs under `$GIT_DIR/refs/heads/` be pushed.
69 Instead of naming each ref to push, specifies that all
70 refs under `$GIT_DIR/refs/heads/` and `$GIT_DIR/refs/tags/`
71 be mirrored to the remote repository. Newly created local
72 refs will be pushed to the remote end, locally updated refs
73 will be force updated on the remote end, and deleted refs
74 will be removed from the remote end. This is the default
75 if the configuration option `remote.<remote>.mirror` is
79 Do everything except actually send the updates.
82 All refs under `$GIT_DIR/refs/tags` are pushed, in
83 addition to refspecs explicitly listed on the command
86 \--receive-pack=<git-receive-pack>::
87 Path to the 'git-receive-pack' program on the remote
88 end. Sometimes useful when pushing to a remote
89 repository over ssh, and you do not have the program in
90 a directory on the default $PATH.
92 \--exec=<git-receive-pack>::
93 Same as \--receive-pack=<git-receive-pack>.
96 Usually, the command refuses to update a remote ref that is
97 not an ancestor of the local ref used to overwrite it.
98 This flag disables the check. This can cause the
99 remote repository to lose commits; use it with care.
102 When no repository is specified the command defaults to
103 "origin"; this overrides it.
105 \--thin, \--no-thin::
106 These options are passed to `git-send-pack`. Thin
107 transfer spends extra cycles to minimize the number of
108 objects to be sent and meant to be used on slower connection.

118 The output of "git push" depends on the transport method used; this
119 section describes the output when pushing over the git protocol (either
122 The status of the push is output in tabular form, with each line
123 representing the status of a single ref. Each line is of the form:
125 -------------------------------
126 <flag> <summary> <from> -> <to> (<reason>)
127 -------------------------------
130 A single character indicating the status of the ref. This is
131 blank for a successfully pushed ref, `!` for a ref that was
132 rejected or failed to push, and '=' for a ref that was up to
133 date and did not need pushing (note that the status of up to
134 date refs is shown only when `git push` is running verbosely).
137 For a successfully pushed ref, the summary shows the old and new
138 values of the ref in a form suitable for using as an argument to
139 `git log` (this is `<old>..<new>` in most cases, and
140 `<old>...<new>` for forced non-fast forward updates). For a
141 failed update, more details are given for the failure.
142 The string `rejected` indicates that git did not try to send the
143 ref at all (typically because it is not a fast forward). The
144 string `remote rejected` indicates that the remote end refused
145 the update; this rejection is typically caused by a hook on the
146 remote side. The string `remote failure` indicates that the
147 remote end did not report the successful update of the ref
148 (perhaps because of a temporary error on the remote side, a
149 break in the network connection, or other transient error).
152 The name of the local ref being pushed, minus its
153 `refs/<type>/` prefix. In the case of deletion, the
154 name of the local ref is omitted.
157 The name of the remote ref being updated, minus its
158 `refs/<type>/` prefix.
161 A human-readable explanation. In the case of successfully pushed
162 refs, no explanation is needed. For a failed ref, the reason for
163 failure is described.
168 git push origin master::
169 Find a ref that matches `master` in the source repository
170 (most likely, it would find `refs/heads/master`), and update
171 the same ref (e.g. `refs/heads/master`) in `origin` repository
172 with it. If `master` did not exist remotely, it would be
175 git push origin :experimental::
176 Find a ref that matches `experimental` in the `origin` repository
177 (e.g. `refs/heads/experimental`), and delete it.
179 git push origin master:satellite/master::
180 Find a ref that matches `master` in the source repository
181 (most likely, it would find `refs/heads/master`), and update
182 the ref that matches `satellite/master` (most likely, it would
183 be `refs/remotes/satellite/master`) in `origin` repository with it.
185 git push origin master:refs/heads/experimental::
186 Create the branch `experimental` in the `origin` repository
187 by copying the current `master` branch. This form is only
188 needed to create a new branch or tag in the remote repository when
189 the local name and the remote name are different; otherwise,
190 the ref name on its own will work.
