NAME
git-push - Update remote refs along with associated objects
SYNOPSIS
git-push [--all] [--tags] [--receive-pack=<git-receive-pack>]
[--repo=all] [-f | --force] [-v] [<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 git-receive-pack(1).
OPTIONS
<repository>
The "remote" repository that is destination of a push operation. See the section GIT URLS below.
<refspec>
The canonical format of a <refspec> parameter is +?<src>:<dst>; that is, an optional plus +, followed by the source ref, followed by a colon :, followed by the destination ref.
The <src> side can be an arbitrary "SHA1 expression" that can be used as an argument to git-cat-file -t. E.g. master~4 (push four parents before the current master head).
The local ref that matches <src> is used to fast forward the remote ref that matches <dst>. If the optional plus + is used, the remote ref is updated even if it does not result in a fast forward update.
Note: 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), then all the refs that exist both on the local side and on the remote side are updated.
tag <tag> means the same as refs/tags/<tag>:refs/tags/<tag>.
A parameter <ref> without a colon is equivalent to <ref>:<ref>, hence updates <ref> in the destination from <ref> in the source.
Pushing an empty <src> allows you to delete the <dst> ref from the remote repository.
--all
Instead of naming each ref to push, specifies that all refs be pushed.
--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>
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.
--exec=<git-receive-pack>
Same as --receive-pack=<git-receive-pack>.
-f, --force
Usually, the command refuses to update a remote ref that is not a descendant 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=<repo>
When no repository is specified the command defaults to "origin"; this overrides it.
--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.
GIT URLS
One of the following notations can be used to name the remote repository:
\h'-04'\h'+03'rsync://host.xz/path/to/repo.git/
\h'-04'\h'+03'http://host.xz/path/to/repo.git/
\h'-04'\h'+03'https://host.xz/path/to/repo.git/
\h'-04'\h'+03'git://host.xz/path/to/repo.git/
\h'-04'\h'+03'git://host.xz/~user/path/to/repo.git/
\h'-04'\h'+03'ssh://[user@]host.xz/path/to/repo.git/
\h'-04'\h'+03'ssh://[user@]host.xz/~user/path/to/repo.git/
\h'-04'\h'+03'ssh://[user@]host.xz/~/path/to/repo.git
SSH is the default transport protocol. You can optionally specify which user to log-in as, and an alternate, scp-like syntax is also supported. Both syntaxes support username expansion, as does the native git protocol. The following three are identical to the last three above, respectively:
\h'-04'\h'+03'[user@]host.xz:/path/to/repo.git/
\h'-04'\h'+03'[user@]host.xz:~user/path/to/repo.git/
\h'-04'\h'+03'[user@]host.xz:path/to/repo.git
To sync with a local directory, use:
\h'-04'\h'+03'/path/to/repo.git/
REMOTES
In addition to the above, as a short-hand, the name of a file in $GIT_DIR/remotes directory can be given; the named file should be in the following format:
.ft C
URL: one of the above URL format
Push: <refspec>
Pull: <refspec>
.ft
Then such a short-hand is specified in place of <repository> without <refspec> parameters on the command line, <refspec> specified on Push: lines or Pull: lines are used for git-push and git-fetch/git-pull, respectively. Multiple Push: and Pull: lines may be specified for additional branch mappings.
Or, equivalently, in the $GIT_DIR/config (note the use of fetch instead of Pull:):
.ft C
[remote "<remote>"]
url = <url>
push = <refspec>
fetch = <refspec>
.ft
The name of a file in $GIT_DIR/branches directory can be specified as an older notation short-hand; the named file should contain a single line, a URL in one of the above formats, optionally followed by a hash # and the name of remote head (URL fragment notation). $GIT_DIR/branches/<remote> file that stores a <url> without the fragment is equivalent to have this in the corresponding file in the $GIT_DIR/remotes/ directory.
.ft C
URL: <url>
Pull: refs/heads/master:<remote>
.ft
while having <url>#<head> is equivalent to
.ft C
URL: <url>
Pull: refs/heads/<head>:<remote>
.ft
