  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 `$GIT_DIR/refs/tags/`
  70        be mirrored to the remote repository.  Newly created local
  71        refs will be pushed to the remote end, locally updated refs
  72        will be force updated on the remote end, and deleted refs
  73        will be removed from the remote end.
  74
  75\--dry-run::
  76        Do everything except actually send the updates.
  77
  78\--tags::
  79        All refs under `$GIT_DIR/refs/tags` are pushed, in
  80        addition to refspecs explicitly listed on the command
  81        line.
  82
  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.
  88
  89\--exec=<git-receive-pack>::
  90        Same as \--receive-pack=<git-receive-pack>.
  91
  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.
  97
  98\--repo=<repo>::
  99        When no repository is specified the command defaults to
 100        "origin"; this overrides it.
 101
 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.
 106
 107-v, \--verbose::
 108        Run verbosely.

 112OUTPUT
 113------
 114
 115The output of "git push" depends on the transport method used; this
 116section describes the output when pushing over the git protocol (either
 117locally or via ssh).
 118
 119The status of the push is output in tabular form, with each line
 120representing the status of a single ref. Each line is of the form:
 121
 122-------------------------------
 123 <flag> <summary> <from> -> <to> (<reason>)
 124-------------------------------
 125
 126flag::
 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).
 132
 133summary::
 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).
 147
 148from::
 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.
 152
 153to::
 154        The name of the remote ref being updated, minus its
 155        `refs/<type>/` prefix.
 156
 157reason::
 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.
 161
 162Examples
 163--------
 164
 165git 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.
 171
 172git push origin :experimental::
 173        Find a ref that matches `experimental` in the `origin` repository
 174        (e.g. `refs/heads/experimental`), and delete it.
 175
 176git 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.
 181
 182git 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.
