  15DESCRIPTION
  16-----------
  17
  18Updates remote refs using local refs, while sending objects
  19necessary to complete the given refs.
  20
  21You can make interesting things happen to a repository
  22every time you push into it, by setting up 'hooks' there.  See
  23documentation for linkgit:git-receive-pack[1].

  26OPTIONS
  27-------
  28<repository>::
  29        The "remote" repository that is destination of a push
  30        operation.  See the section <<URLS,GIT URLS>> below.
  31
  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+
  38The <src> side represents the source branch (or arbitrary
  39"SHA1 expression", such as `master~4` (four parents before the
  40tip of `master` branch); see linkgit:git-rev-parse[1]) that you
  41want to push.  The <dst> side represents the destination location.
  42+
  43The local ref that matches <src> is used
  44to fast forward the remote ref that matches <dst> (or, if no <dst> was
  45specified, the same ref that <src> referred to locally).  If
  46the optional leading plus `+` is used, the remote ref is updated
  47even if it does not result in a fast forward update.
  48+
  49Note: If no explicit refspec is found, (that is neither
  50on the command line nor in any Push line of the
  51corresponding remotes file---see below), then "matching" heads are
  52pushed: for every head that exists on the local side, the remote side is
  53updated 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+
  57A parameter <ref> without a colon pushes the <ref> from the source
  58repository to the destination repository under the same name.
  59+
  60Pushing an empty <src> allows you to delete the <dst> ref from
  61the remote repository.
  62
  63\--all::
  64        Instead of naming each ref to push, specifies that all
  65        refs under `$GIT_DIR/refs/heads/` be pushed.
  66
  67\--mirror::
  68        Instead of naming each ref to push, specifies that all
  69        refs under `$GIT_DIR/refs/heads/` and `$GIT_DIR/refs/tags/`
  70        be mirrored to the remote repository.  Newly created local
  71        refs will be pushed to the remote end, locally updated refs
  72        will be force updated on the remote end, and deleted refs
  73        will be removed from the remote end.  This is the default
  74        if the configuration option `remote.<remote>.mirror` is
  75        set.
  76
  77\--dry-run::
  78        Do everything except actually send the updates.
  79
  80\--tags::
  81        All refs under `$GIT_DIR/refs/tags` are pushed, in
  82        addition to refspecs explicitly listed on the command
  83        line.
  84
  85\--receive-pack=<git-receive-pack>::
  86        Path to the 'git-receive-pack' program on the remote
  87        end.  Sometimes useful when pushing to a remote
  88        repository over ssh, and you do not have the program in
  89        a directory on the default $PATH.
  90
  91\--exec=<git-receive-pack>::
  92        Same as \--receive-pack=<git-receive-pack>.
  93
  94-f, \--force::
  95        Usually, the command refuses to update a remote ref that is
  96        not an ancestor of the local ref used to overwrite it.
  97        This flag disables the check.  This can cause the
  98        remote repository to lose commits; use it with care.
  99
 100\--repo=<repo>::
 101        When no repository is specified the command defaults to
 102        "origin"; this overrides it.
 103
 104\--thin, \--no-thin::
 105        These options are passed to `git-send-pack`.  Thin
 106        transfer spends extra cycles to minimize the number of
 107        objects to be sent and meant to be used on slower connection.
 108
 109-v, \--verbose::
 110        Run verbosely.

 114OUTPUT
 115------
 116
 117The output of "git push" depends on the transport method used; this
 118section describes the output when pushing over the git protocol (either
 119locally or via ssh).
 120
 121The status of the push is output in tabular form, with each line
 122representing the status of a single ref. Each line is of the form:
 123
 124-------------------------------
 125 <flag> <summary> <from> -> <to> (<reason>)
 126-------------------------------
 127
 128flag::
 129        A single character indicating the status of the ref. This is
 130        blank for a successfully pushed ref, `!` for a ref that was
 131        rejected or failed to push, and '=' for a ref that was up to
 132        date and did not need pushing (note that the status of up to
 133        date refs is shown only when `git push` is running verbosely).
 134
 135summary::
 136        For a successfully pushed ref, the summary shows the old and new
 137        values of the ref in a form suitable for using as an argument to
 138        `git log` (this is `<old>..<new>` in most cases, and
 139        `<old>...<new>` for forced non-fast forward updates). For a
 140        failed update, more details are given for the failure.
 141        The string `rejected` indicates that git did not try to send the
 142        ref at all (typically because it is not a fast forward). The
 143        string `remote rejected` indicates that the remote end refused
 144        the update; this rejection is typically caused by a hook on the
 145        remote side. The string `remote failure` indicates that the
 146        remote end did not report the successful update of the ref
 147        (perhaps because of a temporary error on the remote side, a
 148        break in the network connection, or other transient error).
 149
 150from::
 151        The name of the local ref being pushed, minus its
 152        `refs/<type>/` prefix. In the case of deletion, the
 153        name of the local ref is omitted.
 154
 155to::
 156        The name of the remote ref being updated, minus its
 157        `refs/<type>/` prefix.
 158
 159reason::
 160        A human-readable explanation. In the case of successfully pushed
 161        refs, no explanation is needed. For a failed ref, the reason for
 162        failure is described.
 163
 164Examples
 165--------
 166
 167git push origin master::
 168        Find a ref that matches `master` in the source repository
 169        (most likely, it would find `refs/heads/master`), and update
 170        the same ref (e.g. `refs/heads/master`) in `origin` repository
 171        with it.  If `master` did not exist remotely, it would be
 172        created.
 173
 174git push origin :experimental::
 175        Find a ref that matches `experimental` in the `origin` repository
 176        (e.g. `refs/heads/experimental`), and delete it.
 177
 178git push origin master:satellite/master::
 179        Find a ref that matches `master` in the source repository
 180        (most likely, it would find `refs/heads/master`), and update
 181        the ref that matches `satellite/master` (most likely, it would
 182        be `refs/remotes/satellite/master`) in `origin` repository with it.
 183
 184git push origin master:refs/heads/experimental::
 185        Create the branch `experimental` in the `origin` repository
 186        by copying the current `master` branch.  This form is only
 187        needed to create a new branch or tag in the remote repository when
 188        the local name and the remote name are different; otherwise,
 189        the ref name on its own will work.
