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.*.remoteconfiguration 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, --tagsoptions, 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).

<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 asmaster~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 omitted—​such a push will update a ref that <src> normally updates without any <refspec> on the command line. Otherwise, missing :<dst> means to update the same ref as the <src>.

The object referenced by <src> is used to update the <dst> reference on the remote side. By default this is only allowed if <dst> is not a tag (annotated or lightweight), and then only if it can fast-forward <dst>. By having the optional leading +, you can tell Git to update the <dst> ref even if it is not allowed by default (e.g., it 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.

--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/foodoesn’t exist.

--mirror

Instead of naming each ref to push, specifies that all refs under refs/ (which includes but is not limited torefs/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).

--[no-]signed

--sign=(true|false|if-asked)

GPG-sign the push request to update refs on the receiving side, to allow it to be checked by the hooks and/or be logged. Iffalse or --no-signed, no signing will be attempted. If true or --signed, the push will fail if the server does not support signed pushes. If set to if-asked, sign if and only if the server supports signed pushes. The push will also fail if the actual call to gpg --sign fails. See git-receive-pack(1) for the details on the receiving end.

--[no-]atomic

Use an atomic transaction on the remote side if available. Either 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 --force-with-lease on the command line.

-f

--force

Usually, the command refuses to update a remote ref that is not an ancestor of the local ref used to overwrite it. Also, when --force-with-lease option is used, the command refuses to update a remote ref whose current value does not match what is expected.

This flag disables these checks, and can cause the remote repository to lose commits; use it with care.

Note that --force applies to all the refs that are pushed, hence 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-lessgit-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.

--recurse-submodules=check|on-demand

Make sure all submodule commits used by the revisions to be pushed are available on a remote-tracking branch. If checkis 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.

--[no-]verify

Toggle the pre-push hook (see githooks(5)). The default is --verify, giving the hook a chance to prevent the push. With --no-verify, the hook is bypassed completely.

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 supports ssh, git, http, and https protocols (in addition, ftp, and ftps can be used for fetching and rsync can be used for fetching and pushing, but these are inefficient and deprecated; do not use them).

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:

• 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/

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:

• 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 used:

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

For example, with this:

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:

For example, with this:

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.

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

	[remote "<name>"]

		url = <url>

		pushurl = <pushurl>

		push = <refspec>

		fetch = <refspec>

Named file in $GIT_DIR/remotes

	URL: one of the above URL format

	Push: <refspec>

	Pull: <refspec>

Named file in $GIT_DIR/branches

	<url>#<head>

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

	HEAD:refs/heads/<head>

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:

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

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

=

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

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:

rejected

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 orreceive.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.

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 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.

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) or 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 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.

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, pushes the current branch to the configured upstream (remote.origin.mergeconfiguration 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 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 mothership master:satellite/master dev:satellite/dev

Use the source ref that matches master (e.g. refs/heads/master) to update the ref that matchessatellite/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 mergethere 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)

		     /

	    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.
