9 SYNOPSIS
10 --------
11 'git-push' [--all] [--tags] [-f | --force] <repository> <refspec>...
12
13 DESCRIPTION
14 -----------
15
16 Updates remote refs using local refs, while sending objects
17 necessary to complete the given refs.
18
19 You can make interesting things happen to a repository
20 every time you push into it, by setting up 'hooks' there. See
21 documentation for gitlink:git-receive-pack[1].

24 OPTIONS
25 -------
26 <repository>::
27 The "remote" repository that is destination of a push
28 operation. See the section <<URLS,GIT URLS>> below.
29
30 <refspec>::
31 The canonical format of a <refspec> parameter is
32 `+?<src>:<dst>`; that is, an optional plus `+`, followed
33 by the source ref, followed by a colon `:`, followed by
34 the destination ref.
35 +
36 The <src> side can be an
37 arbitrary "SHA1 expression" that can be used as an
38 argument to `git-cat-file -t`. E.g. `master~4` (push
39 four parents before the current master head).
40 +
41 The local ref that matches <src> is used
42 to fast forward the remote ref that matches <dst>. If
43 the optional plus `+` is used, the remote ref is updated
44 even if it does not result in a fast forward update.
45 +
46 Note: If no explicit refspec is found, (that is neither
47 on the command line nor in any Push line of the
48 corresponding remotes file---see below), then all the
49 refs that exist both on the local side and on the remote
50 side are updated.
51 +
52 Some short-cut notations are also supported.
53 +
54 * `tag <tag>` means the same as `refs/tags/<tag>:refs/tags/<tag>`.
55 * A parameter <ref> without a colon is equivalent to
56 <ref>`:`<ref>, hence updates <ref> in the destination from <ref>
57 in the source.
58
59 \--all::
60 Instead of naming each ref to push, specifies that all
61 refs be pushed.
62
63 \--tags::
64 All refs under `$GIT_DIR/refs/tags` are pushed, in
65 addition to refspecs explicitly listed on the command
66 line.
67
68 -f, \--force::
69 Usually, the command refuses to update a remote ref that is
70 not a descendant of the local ref used to overwrite it.
71 This flag disables the check. This can cause the
72 remote repository to lose commits; use it with care.
