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/` (which includes but is not
71 limited to `refs/heads/`, `refs/remotes/`, and `refs/tags/`)
72 be mirrored to the remote repository. Newly created local
73 refs will be pushed to the remote end, locally updated refs
74 will be force updated on the remote end, and deleted refs
75 will be removed from the remote end. This is the default
76 if the configuration option `remote.<remote>.mirror` is
80 Do everything except actually send the updates.
83 All refs under `$GIT_DIR/refs/tags` are pushed, in
84 addition to refspecs explicitly listed on the command
87 --receive-pack=<git-receive-pack>::
88 Path to the `git-receive-pack` program on the remote
89 end. Sometimes useful when pushing to a remote
90 repository over ssh, and you do not have the program in
91 a directory on the default $PATH.
93 --exec=<git-receive-pack>::
94 Same as \--receive-pack=<git-receive-pack>.
98 Usually, the command refuses to update a remote ref that is
99 not an ancestor of the local ref used to overwrite it.
100 This flag disables the check. This can cause the
101 remote repository to lose commits; use it with care.
104 When no repository is specified the command defaults to
105 "origin"; this overrides it.
109 These options are passed to `git-send-pack`. Thin
110 transfer spends extra cycles to minimize the number of
111 objects to be sent and meant to be used on slower connection.

122 The output of "git push" depends on the transport method used; this
123 section describes the output when pushing over the git protocol (either
126 The status of the push is output in tabular form, with each line
127 representing the status of a single ref. Each line is of the form:
129 -------------------------------
130 <flag> <summary> <from> -> <to> (<reason>)
131 -------------------------------
134 A single character indicating the status of the ref. This is
135 blank for a successfully pushed ref, `!` for a ref that was
136 rejected or failed to push, and '=' for a ref that was up to
137 date and did not need pushing (note that the status of up to
138 date refs is shown only when `git push` is running verbosely).
141 For a successfully pushed ref, the summary shows the old and new
142 values of the ref in a form suitable for using as an argument to
143 `git log` (this is `<old>..<new>` in most cases, and
144 `<old>...<new>` for forced non-fast forward updates). For a
145 failed update, more details are given for the failure.
146 The string `rejected` indicates that git did not try to send the
147 ref at all (typically because it is not a fast forward). The
148 string `remote rejected` indicates that the remote end refused
149 the update; this rejection is typically caused by a hook on the
150 remote side. The string `remote failure` indicates that the
151 remote end did not report the successful update of the ref
152 (perhaps because of a temporary error on the remote side, a
153 break in the network connection, or other transient error).
156 The name of the local ref being pushed, minus its
157 `refs/<type>/` prefix. In the case of deletion, the
158 name of the local ref is omitted.
161 The name of the remote ref being updated, minus its
162 `refs/<type>/` prefix.
165 A human-readable explanation. In the case of successfully pushed
166 refs, no explanation is needed. For a failed ref, the reason for
167 failure is described.
172 git push origin master::
173 Find a ref that matches `master` in the source repository
174 (most likely, it would find `refs/heads/master`), and update
175 the same ref (e.g. `refs/heads/master`) in `origin` repository
176 with it. If `master` did not exist remotely, it would be
179 git push origin :experimental::
180 Find a ref that matches `experimental` in the `origin` repository
181 (e.g. `refs/heads/experimental`), and delete it.
183 git push origin master:satellite/master::
184 Find a ref that matches `master` in the source repository
185 (most likely, it would find `refs/heads/master`), and update
186 the ref that matches `satellite/master` (most likely, it would
187 be `refs/remotes/satellite/master`) in `origin` repository with it.
189 git push origin master:refs/heads/experimental::
190 Create the branch `experimental` in the `origin` repository
191 by copying the current `master` branch. This form is only
192 needed to create a new branch or tag in the remote repository when
193 the local name and the remote name are different; otherwise,
194 the ref name on its own will work.
