9 SYNOPSIS
10 --------
11 [verse]
12 'git-push' [--all] [--dry-run] [--tags] [--receive-pack=<git-receive-pack>]
13 [--repo=all] [-f | --force] [-v | --verbose] [<repository> <refspec>...]
15 DESCRIPTION
16 -----------
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].
26 OPTIONS
27 -------
28 <repository>::
29 The "remote" repository that is destination of a push
30 operation. See the section <<URLS,GIT URLS>> below.
32 <refspec>::
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
36 the destination ref.
37 +
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.
42 +
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.
48 +
49 Note: If no explicit refspec is found, (that is neither
50 on the command line nor in any Push line of the
51 corresponding remotes file---see below), then "matching" heads are
52 pushed: for every head that exists on the local side, the remote side is
53 updated if a head of the same name already exists on the remote side.
54 +
55 `tag <tag>` means the same as `refs/tags/<tag>:refs/tags/<tag>`.
56 +
57 A parameter <ref> without a colon pushes the <ref> from the source
58 repository to the destination repository under the same name.
59 +
60 Pushing an empty <src> allows you to delete the <dst> ref from
61 the remote repository.
63 \--all::
64 Instead of naming each ref to push, specifies that all
65 refs under `$GIT_DIR/refs/heads/` be pushed.
67 \--mirror::
68 Instead of naming each ref to push, specifies that all
69 refs under `$GIT_DIR/refs/heads/` and `$GIT_DIR/refs/tags/`
70 be mirrored to the remote repository. Newly created local
71 refs will be pushed to the remote end, locally updated refs
72 will be force updated on the remote end, and deleted refs
73 will be removed from the remote end.
75 \--dry-run::
76 Do everything except actually send the updates.
78 \--tags::
79 All refs under `$GIT_DIR/refs/tags` are pushed, in
80 addition to refspecs explicitly listed on the command
81 line.
83 \--receive-pack=<git-receive-pack>::
84 Path to the 'git-receive-pack' program on the remote
85 end. Sometimes useful when pushing to a remote
86 repository over ssh, and you do not have the program in
87 a directory on the default $PATH.
89 \--exec=<git-receive-pack>::
90 Same as \--receive-pack=<git-receive-pack>.
92 -f, \--force::
93 Usually, the command refuses to update a remote ref that is
94 not an ancestor of the local ref used to overwrite it.
95 This flag disables the check. This can cause the
96 remote repository to lose commits; use it with care.
98 \--repo=<repo>::
99 When no repository is specified the command defaults to
100 "origin"; this overrides it.
102 \--thin, \--no-thin::
103 These options are passed to `git-send-pack`. Thin
104 transfer spends extra cycles to minimize the number of
105 objects to be sent and meant to be used on slower connection.
107 -v, \--verbose::
108 Run verbosely.

112 OUTPUT
113 ------
115 The output of "git push" depends on the transport method used; this
116 section describes the output when pushing over the git protocol (either
117 locally or via ssh).
119 The status of the push is output in tabular form, with each line
120 representing the status of a single ref. Each line is of the form:
122 -------------------------------
123 <flag> <summary> <from> -> <to> (<reason>)
124 -------------------------------
126 flag::
127 A single character indicating the status of the ref. This is
128 blank for a successfully pushed ref, `!` for a ref that was
129 rejected or failed to push, and '=' for a ref that was up to
130 date and did not need pushing (note that the status of up to
131 date refs is shown only when `git push` is running verbosely).
133 summary::
134 For a successfully pushed ref, the summary shows the old and new
135 values of the ref in a form suitable for using as an argument to
136 `git log` (this is `<old>..<new>` in most cases, and
137 `<old>...<new>` for forced non-fast forward updates). For a
138 failed update, more details are given for the failure.
139 The string `rejected` indicates that git did not try to send the
140 ref at all (typically because it is not a fast forward). The
141 string `remote rejected` indicates that the remote end refused
142 the update; this rejection is typically caused by a hook on the
143 remote side. The string `remote failure` indicates that the
144 remote end did not report the successful update of the ref
145 (perhaps because of a temporary error on the remote side, a
146 break in the network connection, or other transient error).
148 from::
149 The name of the local ref being pushed, minus its
150 `refs/<type>/` prefix. In the case of deletion, the
151 name of the local ref is omitted.
153 to::
154 The name of the remote ref being updated, minus its
155 `refs/<type>/` prefix.
157 reason::
158 A human-readable explanation. In the case of successfully pushed
159 refs, no explanation is needed. For a failed ref, the reason for
160 failure is described.
162 Examples
163 --------
165 git push origin master::
166 Find a ref that matches `master` in the source repository
167 (most likely, it would find `refs/heads/master`), and update
168 the same ref (e.g. `refs/heads/master`) in `origin` repository
169 with it. If `master` did not exist remotely, it would be
170 created.
172 git push origin :experimental::
173 Find a ref that matches `experimental` in the `origin` repository
174 (e.g. `refs/heads/experimental`), and delete it.
176 git push origin master:satellite/master::
177 Find a ref that matches `master` in the source repository
178 (most likely, it would find `refs/heads/master`), and update
179 the ref that matches `satellite/master` (most likely, it would
180 be `refs/remotes/satellite/master`) in `origin` repository with it.
182 git push origin master:refs/heads/experimental::
183 Create the branch `experimental` in the `origin` repository
184 by copying the current `master` branch. This form is only
185 needed to create a new branch or tag in the remote repository when
186 the local name and the remote name are different; otherwise,
187 the ref name on its own will work.
