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 git-
       receive-pack(1).

       When the command line does not specify where to push with the
       <repository> argument, branch.*.remote configuration for the current
       branch is consulted to determine where to push. If the configuration is
       missing, it defaults to origin.

       When the command line does not specify what to push with <refspec>...
       arguments or --all, --mirror, --tags options, the command finds the
       default <refspec> by consulting remote.*.push configuration, and if it
       is not found, honors push.default configuration to decide what to push
       (See git-config(1) for the meaning of push.default).

       When neither the command-line nor the configuration specify what to
       push, the default behavior is used, which corresponds to the simple
       value for push.default: the current branch is pushed to the
       corresponding upstream branch, but as a safety measure, the push is
       aborted if the upstream branch does not have the same name as the local
       one.

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

       <refspec>...
           Specify what destination ref to update with what source object. The
           format of a <refspec> parameter is an optional plus +, followed by
           the source object <src>, followed by a colon :, followed by the
           destination ref <dst>.

           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 gitrevisions(7)).

           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 git push [<repository>] without any <refspec> argument
           is set to update some ref at the destination with <src> with
           remote.<repository>.push configuration variable, :<dst> part can be
           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 +: 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.

       --all
           Push all branches (i.e. refs under refs/heads/); cannot be used
           with other <refspec>.

       --prune
           Remove remote branches that don't have a local counterpart. For
           example a remote branch tmp will be removed if a local branch with
           the same name doesn't exist any more. This also respects refspecs,
           e.g.  git push --prune remote refs/heads/*:refs/tmp/* would make
           sure that remote refs/tmp/foo will be removed if refs/heads/foo
           doesn't exist.

       --mirror
           Instead of naming each ref to push, specifies that all refs under
           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.

       -n, --dry-run
           Do everything except actually send the updates.

       --porcelain
           Produce machine-readable output. The output status line for each
           ref will be tab-separated and sent to stdout instead of stderr. The
           full symbolic names of the refs will be given.

       --delete
           All listed refs are deleted from the remote repository. This is the
           same as prefixing all refs with a colon.

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

       --follow-tags
           Push all the refs that would be pushed without this option, and
           also push annotated tags in refs/tags that are missing from the
           remote but are pointing at commit-ish that are reachable from the
           refs being pushed. This can also be specified with configuration
           variable push.followTags. For more information, see push.followTags
           in git-config(1).
           all refs are updated, or on error, no refs are updated. If the
           server does not support atomic pushes the push will fail.

       --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.

       --[no-]force-with-lease, --force-with-lease=<refname>,
       --force-with-lease=<refname>:<expect>
           Usually, "git push" refuses to update a remote ref that is not an
           ancestor of the local ref used to overwrite it.

           This option overrides this restriction if the current value of the
           remote ref is the expected value. "git push" fails otherwise.

           Imagine that you have to rebase what you have already published.
           You will have to bypass the "must fast-forward" rule in order to
           replace the history you originally published with the rebased
           history. If somebody else built on top of your original history
           while you are rebasing, the tip of the branch at the remote may
           advance with her commit, and blindly pushing with --force will lose
           her work.

           This option allows you to say that you expect the history you are
           updating is what you rebased and want to replace. If the remote ref
           still points at the commit you specified, you can be sure that no
           other people did anything to the ref. It is like taking a "lease"
           on the ref without explicitly locking it, and the remote ref is
           updated only if the "lease" is still valid.

           --force-with-lease alone, without specifying the details, will
           protect all remote refs that are going to be updated by requiring
           their current value to be the same as the remote-tracking branch we
           have for them.

           --force-with-lease=<refname>, without specifying the expected
           value, will protect the named ref (alone), if it is going to be
           updated, by requiring its current value to be the same as the
           remote-tracking branch we have for it.

           --force-with-lease=<refname>:<expect> will protect the named ref
           (alone), if it is going to be updated, by requiring its current
           value to be the same as the specified value <expect> (which is
           allowed to be different from the remote-tracking branch we have for
           the refname, or we do not even have to have such a remote-tracking
           branch when this form is used).

           Note that all forms other than
           --force-with-lease=<refname>:<expect> that specifies the expected
           current value of the ref explicitly are still experimental and
           their semantics may change as we gain experience with this feature.

           "--no-force-with-lease" will cancel all the previous
           using it with push.default set to matching or with multiple push
           destinations configured with remote.*.push may overwrite refs other
           than the current branch (including local refs that are strictly
           behind their remote counterpart). To force a push to only one
           branch, use a + in front of the refspec to push (e.g git push
           origin +master to force a push to the master branch). See the
           <refspec>...  section above for details.

       --repo=<repository>
           This option is equivalent to the <repository> argument. If both are
           specified, the command-line argument takes precedence.

       -u, --set-upstream
           For every branch that is up to date or successfully pushed, add
           upstream (tracking) reference, used by argument-less git-pull(1)
           and other commands. For more information, see branch.<name>.merge
           in git-config(1).

       --[no-]thin
           These options are passed to git-send-pack(1). A thin transfer
           significantly reduces the amount of sent data when the sender and
           receiver share many of the same objects in common. The default is
           --thin.

       -q, --quiet
           Suppress all output, including the listing of updated refs, unless
           an error occurs. Progress is not reported to the standard error
           stream.

       -v, --verbose
           Run verbosely.

       --progress
           Progress status is reported on the standard error stream by default
           when it is attached to a terminal, unless -q is specified. This
           flag forces progress status even if the standard error stream is
           not directed to a terminal.

       --no-recurse-submodules, --recurse-submodules=check|on-demand|no
           May be used to make sure all submodule commits used by the
           revisions to be pushed are available on a remote-tracking branch.
           If check is used Git will verify that all submodule commits that
           changed in the revisions to be pushed are available on at least one
           remote of the submodule. If any commits are missing the push will
           be aborted and exit with non-zero status. If on-demand is used all
           submodules that changed in the revisions to be pushed will be
           pushed. If on-demand was not able to push all necessary revisions
           it will also be aborted and exit with non-zero status. A value of
           no or using --no-recurse-submodules can be used to override the
           push.recurseSubmodules configuration variable when no submodule
           recursion is required.

       --[no-]verify
           Toggle the pre-push hook (see githooks(5)). The default is

       The native transport (i.e. git:// URL) does no authentication and
       should be used with caution on unsecured networks.

       The following syntaxes may be used with them:

       o   ssh://[user@]host.xz[:port]/path/to/repo.git/

       o   git://host.xz[:port]/path/to/repo.git/

       o   http[s]://host.xz[:port]/path/to/repo.git/

       o   ftp[s]://host.xz[:port]/path/to/repo.git/

       o   rsync://host.xz/path/to/repo.git/

       An alternative scp-like syntax may also be used with the ssh protocol:

       o   [user@]host.xz:path/to/repo.git/

       This syntax is only recognized if there are no slashes before the first
       colon. This helps differentiate a local path that contains a colon. For
       example the local path foo:bar could be specified as an absolute path
       or ./foo:bar to avoid being misinterpreted as an ssh url.

       The ssh and git protocols additionally support ~username expansion:

       o   ssh://[user@]host.xz[:port]/~[user]/path/to/repo.git/

       o   git://host.xz[:port]/~[user]/path/to/repo.git/

       o   [user@]host.xz:/~[user]/path/to/repo.git/

       For local repositories, also supported by Git natively, the following
       syntaxes may be used:

       o   /path/to/repo.git/

       o   file:///path/to/repo.git/

       These two syntaxes are mostly equivalent, except when cloning, when the
       former implies --local option. See git-clone(1) for details.

       When Git doesn't know how to handle a certain transport protocol, it
       attempts to use the remote-<transport> remote helper, if one exists. To
       explicitly request a remote helper, the following syntax may be used:

       o   <transport>::<address>

       where <address> may be a path, a server and path, or an arbitrary
       URL-like string recognized by the specific remote helper being invoked.
       See gitremote-helpers(1) for details.

       If there are a large number of similarly-named remote repositories and
       you want to use a different format for them (such that the URLs you use
       a URL like "work:repo.git" or like "host.xz:/path/to/repo.git" will be
       rewritten in any context that takes a URL to be
       "git://git.host.xz/repo.git".

       If you want to rewrite URLs for push only, you can create a
       configuration section of the form:

                   [url "<actual url base>"]
                           pushInsteadOf = <other url base>

       For example, with this:

                   [url "ssh://example.org/"]
                           pushInsteadOf = git://example.org/

       a URL like "git://example.org/path/to/repo.git" will be rewritten to
       "ssh://example.org/path/to/repo.git" for pushes, but pulls will still
       use the original URL.

REMOTES
       The name of one of the following can be used instead of a URL as
       <repository> argument:

       o   a remote in the Git configuration file: $GIT_DIR/config,

       o   a file in the $GIT_DIR/remotes directory, or

       o   a file in the $GIT_DIR/branches directory.

       All of these also allow you to omit the refspec from the command line
       because they each contain a refspec which git will use by default.

   Named remote in configuration file
       You can choose to provide the name of a remote which you had previously
       configured using git-remote(1), git-config(1) or even by a manual edit
       to the $GIT_DIR/config file. The URL of this remote will be used to
       access the repository. The refspec of this remote will be used by
       default when you do not provide a refspec on the command line. The
       entry in the config file would appear like this:

                   [remote "<name>"]
                           url = <url>
                           pushurl = <pushurl>
                           push = <refspec>
                           fetch = <refspec>

       The <pushurl> is used for pushes only. It is optional and defaults to
       <url>.

   Named file in $GIT_DIR/remotes
       You can choose to provide the name of a file in $GIT_DIR/remotes. The
       URL in this file will be used to access the repository. The refspec in
       this file will be used as default when you do not provide a refspec on
       the command line. This file should have the following format:
       should have the following format:

                   <url>#<head>

       <url> is required; #<head> is optional.

       Depending on the operation, git will use one of the following refspecs,
       if you don't provide one on the command line. <branch> is the name of
       this file in $GIT_DIR/branches and <head> defaults to master.

       git fetch uses:

                   refs/heads/<head>:refs/heads/<branch>

       git push uses:

                   HEAD:refs/heads/<head>

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>)

       If --porcelain is used, then each line of the output is of the form:

            <flag> \t <from>:<to> \t <summary> (<reason>)

       The status of up-to-date refs is shown only if --porcelain or --verbose
       option is used.

       flag
           A single character indicating the status of the ref:

           (space)
               for a successfully pushed fast-forward;

           +
               for a successful forced update;

           -
               for a successfully deleted ref;

           *
               for a successfully pushed new ref;

           !
               for a ref that was rejected or failed to push; and

           =
               not a fast-forward and you did not force the update.

           remote rejected
               The remote end refused the update. Usually caused by a hook on
               the remote side, or because the remote repository has one of
               the following safety options in effect:
               receive.denyCurrentBranch (for pushes to the checked out
               branch), receive.denyNonFastForwards (for forced
               non-fast-forward updates), receive.denyDeletes or
               receive.denyDeleteCurrent. See git-config(1).

           remote failure
               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.

NOTE ABOUT FAST-FORWARDS
       When an update changes a branch (or more in general, a ref) that used
       to point at commit A to point at another commit B, it is called a
       fast-forward update if and only if B is a descendant of A.

       In a fast-forward update from A to B, the set of commits that the
       original commit A built on top of is a subset of the commits the new
       commit B builds on top of. Hence, it does not lose any history.

       In contrast, a non-fast-forward update will lose history. For example,
       suppose you and somebody else started at the same commit X, and you
       built a history leading to commit B while the other person built a
       history leading to commit A. The history looks like this:

                 B
                /
            ---X---A

       Further suppose that the other person already pushed changes leading to
       A back to the original repository from which you two obtained the
       original commit X.

       The push done by the other person updated the branch that used to point
       at commit X to point at commit A. It is a fast-forward.
       changes done by both parties, and push the result back.

       You can perform "git pull", resolve potential conflicts, and "git push"
       the result. A "git pull" will create a merge commit C between commits A
       and B.

                 B---C
                /   /
            ---X---A

       Updating A with the resulting merge commit will fast-forward and your
       push will be accepted.

       Alternatively, you can rebase your change between X and B on top of A,
       with "git pull --rebase", and push the result back. The rebase will
       create a new commit D that builds the change between X and B on top of
       A.

                 B   D
                /   /
            ---X---A

       Again, updating A with this commit will fast-forward and your push will
       be accepted.

       There is another common situation where you may encounter
       non-fast-forward rejection when you try to push, and it is possible
       even when you are pushing into a repository nobody else pushes into.
       After you push commit A yourself (in the first picture in this
       section), replace it with "git commit --amend" to produce commit B, and
       you try to push it out, because forgot that you have pushed A out
       already. In such a case, and only if you are certain that nobody in the
       meantime fetched your earlier commit A (and started building on top of
       it), you can run "git push --force" to overwrite it. In other words,
       "git push --force" is a method reserved for a case where you do mean to
       lose history.

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, pushes the current branch to the
           configured upstream (remote.origin.merge configuration variable) if
           it has the same name as the current branch, and errors out without
           pushing otherwise.

           The default behavior of this command when no <refspec> is given can
           be configured by setting the push option of the remote, or the
           push.default configuration variable.

           For example, to default to pushing only the current branch to
           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 mothership 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 mothership repository; do the
           same for dev and satellite/dev.

           This is to emulate git fetch run on the mothership using git push
           that is run in the opposite direction in order to integrate the
           work done on satellite, and is often necessary when you can only
           make connection in one way (i.e. satellite can ssh into mothership
           but mothership cannot initiate connection to satellite because the
           latter is behind a firewall or does not run sshd).

           After running this git push on the satellite machine, you would ssh
           into the mothership and run git merge there to complete the
           emulation of git pull that were run on mothership to pull changes
           made on satellite.

       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 +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)
