12 'git-push' [--all] [--dry-run] [--tags] [--receive-pack=<git-receive-pack>]

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].
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 can be an
39 arbitrary "SHA1 expression" that can be used as an
40 argument to `git-cat-file -t`. E.g. `master~4` (push
41 four parents before the current master head).
42 +
43 The local ref that matches <src> is used
44 to fast forward the remote ref that matches <dst>. If
45 the optional plus `+` is used, the remote ref is updated
46 even if it does not result in a fast forward update.
47 +
48 Note: If no explicit refspec is found, (that is neither
49 on the command line nor in any Push line of the
50 corresponding remotes file---see below), then "matching" heads are
51 pushed: for every head that exists on the local side, the remote side is
52 updated if a head of the same name already exists on the remote side.
53 +
54 `tag <tag>` means the same as `refs/tags/<tag>:refs/tags/<tag>`.
55 +
56 A parameter <ref> without a colon pushes the <ref> from the source
57 repository to the destination repository under the same name.
58 +
59 Pushing an empty <src> allows you to delete the <dst> ref from
60 the remote repository.
62 \--all::
63 Instead of naming each ref to push, specifies that all
64 refs under `$GIT_DIR/refs/heads/` be pushed.
66 \--mirror::
67 Instead of naming each ref to push, specifies that all
68 refs under `$GIT_DIR/refs/heads/` and `$GIT_DIR/refs/tags/`
69 be mirrored to the remote repository. Newly created local
70 refs will be pushed to the remote end, locally updated refs
71 will be force updated on the remote end, and deleted refs
72 will be removed from the remote end.
74 \--dry-run::
75 Do everything except actually send the updates.
77 \--tags::
78 All refs under `$GIT_DIR/refs/tags` are pushed, in
79 addition to refspecs explicitly listed on the command
80 line.
82 \--receive-pack=<git-receive-pack>::
83 Path to the 'git-receive-pack' program on the remote
84 end. Sometimes useful when pushing to a remote
85 repository over ssh, and you do not have the program in
86 a directory on the default $PATH.
88 \--exec=<git-receive-pack>::
89 Same as \--receive-pack=<git-receive-pack>.
91 -f, \--force::
92 Usually, the command refuses to update a remote ref that is
93 not an ancestor of the local ref used to overwrite it.
94 This flag disables the check. This can cause the
95 remote repository to lose commits; use it with care.
97 \--repo=<repo>::
98 When no repository is specified the command defaults to
99 "origin"; this overrides it.
101 \--thin, \--no-thin::
102 These options are passed to `git-send-pack`. Thin
103 transfer spends extra cycles to minimize the number of
104 objects to be sent and meant to be used on slower connection.
106 -v, \--verbose::
107 Run verbosely.

112 ------
114 The output of "git push" depends on the transport method used; this
115 section describes the output when pushing over the git protocol (either
116 locally or via ssh).
118 The status of the push is output in tabular form, with each line
119 representing the status of a single ref. Each line is of the form:
121 -------------------------------
122 <flag> <summary> <from> -> <to> (<reason>)
123 -------------------------------
125 flag::
126 A single character indicating the status of the ref. This is
127 blank for a successfully pushed ref, `!` for a ref that was
128 rejected or failed to push, and '=' for a ref that was up to
129 date and did not need pushing (note that the status of up to
130 date refs is shown only when `git push` is running verbosely).
132 summary::
133 For a successfully pushed ref, the summary shows the old and new
134 values of the ref in a form suitable for using as an argument to
135 `git log` (this is `<old>..<new>` in most cases, and
136 `<old>...<new>` for forced non-fast forward updates). For a
137 failed update, more details are given for the failure.
138 The string `rejected` indicates that git did not try to send the
139 ref at all (typically because it is not a fast forward). The
140 string `remote rejected` indicates that the remote end refused
141 the update; this rejection is typically caused by a hook on the
142 remote side. The string `remote failure` indicates that the
143 remote end did not report the successful update of the ref
144 (perhaps because of a temporary error on the remote side, a
145 break in the network connection, or other transient error).
147 from::
148 The name of the local ref being pushed, minus its
149 `refs/<type>/` prefix. In the case of deletion, the
150 name of the local ref is omitted.
152 to::
153 The name of the remote ref being updated, minus its
154 `refs/<type>/` prefix.
156 reason::
157 A human-readable explanation. In the case of successfully pushed
158 refs, no explanation is needed. For a failed ref, the reason for
159 failure is described.
161 Examples
162 --------
164 git push origin master::
165 Find a ref that matches `master` in the source repository
166 (most likely, it would find `refs/heads/master`), and update
167 the same ref (e.g. `refs/heads/master`) in `origin` repository
168 with it.
170 git push origin :experimental::
171 Find a ref that matches `experimental` in the `origin` repository
172 (e.g. `refs/heads/experimental`), and delete it.
174 git push origin master:satellite/master::
175 Find a ref that matches `master` in the source repository
176 (most likely, it would find `refs/heads/master`), and update
177 the ref that matches `satellite/master` (most likely, it would
178 be `refs/remotes/satellite/master`) in `origin` repository with it.
180 git push origin master:refs/heads/experimental::
181 Create the branch `experimental` in the `origin` repository
182 by copying the current `master` branch. This form is usually
183 needed to create a new branch in the remote repository as
184 there is no `experimental` branch to match.
