NAME
----
git-push - Update remote refs along with associated objects


SYNOPSIS
--------
[verse]
'git push' [--all | --mirror | --tags] [--dry-run] [--receive-pack=<git-receive-pack>]
           [--repo=<repository>] [-f | --force] [-v | --verbose]
           [<repository> <refspec>...]

DESCRIPTION
-----------

Updates remote refs using local refs, while sending objects
necessary to complete the given refs.

You can make interesting things happen to a repository
every time you push into it, by setting up 'hooks' there.  See
documentation for linkgit:git-receive-pack[1].


OPTIONS[[OPTIONS]]
------------------
<repository>::
        The "remote" repository that is destination of a push
        operation.  This parameter can be either a URL
        (see the section <<URLS,GIT URLS>> below) or the name
        of a remote (see the section <<REMOTES,REMOTES>> below).

<refspec>...::
        The format of a <refspec> parameter is an optional plus
        `{plus}`, followed by the source ref <src>, followed
        by a colon `:`, followed by the destination ref <dst>.
        It is used to specify with what <src> object the <dst> ref
        in the remote repository is to be updated.
+
The <src> is often the name of the branch you would want to push, but
it can be any arbitrary "SHA-1 expression", such as `master~4` or
`HEAD` (see linkgit:git-rev-parse[1]).
+
The <dst> tells which ref on the remote side is updated with this
push. Arbitrary expressions cannot be used here, an actual ref must
be named. If `:`<dst> is omitted, the same ref as <src> will be
updated.
+
The object referenced by <src> is used to update the <dst> reference
on the remote side, but by default this is only allowed if the
update can fast forward <dst>.  By having the optional leading `{plus}`,
you can tell git to update the <dst> ref even when the update is not a
fast forward.  This does *not* attempt to merge <src> into <dst>.  See
EXAMPLES below for details.
+
`tag <tag>` means the same as `refs/tags/<tag>:refs/tags/<tag>`.
+
Pushing an empty <src> allows you to delete the <dst> ref from
the remote repository.
+
The special refspec `:` (or `{plus}:` to allow non-fast forward updates)
directs git to push "matching" branches: for every branch that exists on
the local side, the remote side is updated if a branch of the same name
already exists on the remote side.  This is the default operation mode
if no explicit refspec is found (that is neither on the command line
nor in any Push line of the corresponding remotes file---see below).

--all::
        Instead of naming each ref to push, specifies that all
        refs under `$GIT_DIR/refs/heads/` be pushed.

--mirror::
        Instead of naming each ref to push, specifies that all
        refs under `$GIT_DIR/refs/` (which includes but is not
        limited to `refs/heads/`, `refs/remotes/`, and `refs/tags/`)
        be mirrored to the remote repository.  Newly created local
        refs will be pushed to the remote end, locally updated refs
        will be force updated on the remote end, and deleted refs
        will be removed from the remote end.  This is the default
        if the configuration option `remote.<remote>.mirror` is
        set.

--dry-run::
        Do everything except actually send the updates.

--tags::
        All refs under `$GIT_DIR/refs/tags` are pushed, in
        addition to refspecs explicitly listed on the command
        line.

--receive-pack=<git-receive-pack>::
--exec=<git-receive-pack>::
        Path to the 'git-receive-pack' program on the remote
        end.  Sometimes useful when pushing to a remote
        repository over ssh, and you do not have the program in
        a directory on the default $PATH.

-f::
--force::
        Usually, the command refuses to update a remote ref that is
        not an ancestor of the local ref used to overwrite it.
        This flag disables the check.  This can cause the
        remote repository to lose commits; use it with care.

--repo=<repository>::
        This option is only relevant if no <repository> argument is
        passed in the invocation. In this case, 'git-push' derives the
        remote name from the current branch: If it tracks a remote
        branch, then that remote repository is pushed to. Otherwise,
        the name "origin" is used. For this latter case, this option
        can be used to override the name "origin". In other words,
        the difference between these two commands
+
--------------------------
git push public         #1
git push --repo=public  #2
--------------------------
+
is that #1 always pushes to "public" whereas #2 pushes to "public"
only if the current branch does not track a remote branch. This is
useful if you write an alias or script around 'git-push'.

--thin::
--no-thin::
        These options are passed to 'git-send-pack'.  Thin
        transfer spends extra cycles to minimize the number of
        objects to be sent and meant to be used on slower connection.

-v::
--verbose::
        Run verbosely.

OUTPUT
------

The output of "git push" depends on the transport method used; this
section describes the output when pushing over the git protocol (either
locally or via ssh).

The status of the push is output in tabular form, with each line
representing the status of a single ref. Each line is of the form:

-------------------------------
 <flag> <summary> <from> -> <to> (<reason>)
-------------------------------

flag::
        A single character indicating the status of the ref. This is
        blank for a successfully pushed ref, `!` for a ref that was
        rejected or failed to push, and '=' for a ref that was up to
        date and did not need pushing (note that the status of up to
        date refs is shown only when `git push` is running verbosely).

summary::
        For a successfully pushed ref, the summary shows the old and new
        values of the ref in a form suitable for using as an argument to
        `git log` (this is `<old>..<new>` in most cases, and
        `<old>...<new>` for forced non-fast forward updates). For a
        failed update, more details are given for the failure.
        The string `rejected` indicates that git did not try to send the
        ref at all (typically because it is not a fast forward). The
        string `remote rejected` indicates that the remote end refused
        the update; this rejection is typically caused by a hook on the
        remote side. The string `remote failure` indicates that the
        remote end did not report the successful update of the ref
        (perhaps because of a temporary error on the remote side, a
        break in the network connection, or other transient error).

from::
        The name of the local ref being pushed, minus its
        `refs/<type>/` prefix. In the case of deletion, the
        name of the local ref is omitted.

to::
        The name of the remote ref being updated, minus its
        `refs/<type>/` prefix.

reason::
        A human-readable explanation. In the case of successfully pushed
        refs, no explanation is needed. For a failed ref, the reason for
        failure is described.

Examples
--------

git push::
        Works like `git push <remote>`, where <remote> is the
        current branch's remote (or `origin`, if no remote is
        configured for the current branch).

git push origin::
        Without additional configuration, works like
        `git push origin :`.
+
The default behavior of this command when no <refspec> is given can be
configured by setting the `push` option of the remote.
+
For example, to default to pushing only the current branch to `origin`
use `git config remote.origin.push HEAD`.  Any valid <refspec> (like
the ones in the examples below) can be configured as the default for
`git push origin`.

git push origin :::
        Push "matching" branches to `origin`. See
        <refspec> in the <<OPTIONS,OPTIONS>> section above for a
        description of "matching" branches.

git push origin master::
        Find a ref that matches `master` in the source repository
        (most likely, it would find `refs/heads/master`), and update
        the same ref (e.g. `refs/heads/master`) in `origin` repository
        with it.  If `master` did not exist remotely, it would be
        created.

git push origin HEAD::
        A handy way to push the current branch to the same name on the
        remote.

git push origin master:satellite/master dev:satellite/dev::
        Use the source ref that matches `master` (e.g. `refs/heads/master`)
        to update the ref that matches `satellite/master` (most probably
        `refs/remotes/satellite/master`) in the `origin` repository, then
        do the same for `dev` and `satellite/dev`.

git push origin HEAD:master::
        Push the current branch to the remote ref matching `master` in the
        `origin` repository. This form is convenient to push the current
        branch without thinking about its local name.

git push origin master:refs/heads/experimental::
        Create the branch `experimental` in the `origin` repository
        by copying the current `master` branch.  This form is only
        needed to create a new branch or tag in the remote repository when
        the local name and the remote name are different; otherwise,
        the ref name on its own will work.

git push origin :experimental::
        Find a ref that matches `experimental` in the `origin` repository
        (e.g. `refs/heads/experimental`), and delete it.

git push origin {plus}dev:master::
        Update the origin repository's master branch with the dev branch,
        allowing non-fast forward updates.  *This can leave unreferenced
        commits dangling in the origin repository.*  Consider the
        following situation, where a fast forward is not possible:
+
----
            o---o---o---A---B  origin/master
                     \
                      X---Y---Z  dev
----
+
The above command would change the origin repository to
+
----
                      A---B  (unnamed branch)
                     /
            o---o---o---X---Y---Z  master
----
+
Commits A and B would no longer belong to a branch with a symbolic name,
and so would be unreachable.  As such, these commits would be removed by
a `git gc` command on the origin repository.
