       git-push - Update remote refs along with associated objects


       git push [--all | --mirror | --tags] [-n | --dry-run] [--receive-pack=<git-receive-pack>]
                  [--repo=<repository>] [-f | --force] [-v | --verbose] [-u | --set-upstream]
                  [<repository> [<refspec>...]]


       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).


           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).

           The format of a <refspec> parameter is an optional 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

           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 :<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 +, 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 +: 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).

           Instead of naming each ref to push, specifies that all refs under refs/heads/ be

           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.

           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.

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

           All refs under 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.

           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.

       -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).

       --thin, --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 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.

           Check whether all submodule commits used by the revisions to be pushed are available
           on a remote tracking branch. Otherwise the push will be aborted and the command will
           exit with non-zero status.


       In general, URLs contain information about the transport protocol, the address of the
       remote server, and the path to the repository. Depending on the transport protocol, some
       of this information may be absent.

       Git natively supports ssh, git, http, https, ftp, ftps, and rsync protocols. The following
       syntaxes may be used with them:

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

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

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

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

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

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

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

       The ssh and git protocols additionally support ~username expansion:

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

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

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

       For local repositories, also supported by git natively, the following syntaxes may be

       ·   /path/to/repo.git/

       ·    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:

       ·   <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 git-remote-helpers(1) for

       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 will be rewritten into URLs that
       work), you can create a configuration section of the form:

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

       For example, with this:

                   [url "git://"]
                           insteadOf = host.xz:/path/to/
                           insteadOf = work:

       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://".

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

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

       For example, with this:

                   [url "ssh://"]
                           pushInsteadOf = git://

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


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

       ·   a remote in the git configuration file: $GIT_DIR/config,

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

       ·   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

                   URL: one of the above URL format
                   Push: <refspec>
                   Pull: <refspec>

       Push: lines are used by git push and Pull: lines are used by git pull and git fetch.
       Multiple Push: and Pull: lines may be specified for additional branch mappings.

   Named file in $GIT_DIR/branches
       You can choose to provide the name of a file in $GIT_DIR/branches. The URL in this file
       will be used to access the repository. This file should have the following format:


       <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:


       git push uses:



       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.

           A single character indicating the status of the ref:

               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

               for a ref that was up to date and did not need pushing.

           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:

               Git did not try to send the ref at all, typically because it is 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.

           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.

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

           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.


       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:


       Further suppose that the other person already pushed changes leading to A back to the
       original repository 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.

       But if you try to push, you will attempt to update the branch (that now points at A) with
       commit B. This does not fast-forward. If you did so, the changes introduced by commit A
       will be lost, because everybody will now start building on top of B.

       The command by default does not allow an update that is not a fast-forward to prevent such
       loss of history.

       If you do not want to lose your work (history from X to B) nor the work by the other
       person (history from X to A), you would need to first fetch the history from the
       repository, create a history that contains 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.

                /   /

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

       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
                /   /

       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.


       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 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

       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)
                           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.
