NAME

       git-send-pack - Push objects over Git protocol to another repository

SYNOPSIS

       git send-pack [--mirror] [--dry-run] [--force]
                       [--receive-pack=<git-receive-pack>]
                       [--verbose] [--thin] [--atomic]
                       [--[no-]signed | --signed=(true|false|if-asked)]
                       [<host>:]<directory> (--all | <ref>...)

DESCRIPTION

       Usually you would want to use git push, which is a higher-level wrapper of this command,
       instead. See git-push(1).

       Invokes git-receive-pack on a possibly remote repository, and updates it from the current
       repository, sending named refs.

OPTIONS

       --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>.

       --all
           Instead of explicitly specifying which refs to update, update all heads that locally
           exist.

       --stdin
           Take the list of refs from stdin, one per line. If there are refs specified on the
           command line in addition to this option, then the refs from stdin are processed after
           those on the command line.

           If --stateless-rpc is specified together with this option then the list of refs must
           be in packet format (pkt-line). Each ref must be in a separate packet, and the list
           must end with a flush packet.

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

       --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 means that the
           remote repository can lose commits; use it with care.

       --verbose
           Run verbosely.

       --thin
           Send a "thin" pack, which records objects in deltified form based on objects not
           included in the pack to reduce network traffic.

       --atomic
           Use an atomic transaction for updating the refs. If any of the refs fails to update
           then the entire push will fail without changing any refs.

       --[no-]signed, --signed=(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. If false 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.

       --push-option=<string>
           Pass the specified string as a push option for consumption by hooks on the server
           side. If the server doesn’t support push options, error out. See git-push(1) and
           githooks(5) for details.

       <host>
           A remote host to house the repository. When this part is specified, git-receive-pack
           is invoked via ssh.

       <directory>
           The repository to update.

       <ref>...
           The remote refs to update.

SPECIFYING THE REFS

       There are three ways to specify which refs to update on the remote end.

       With the --all flag, all refs that exist locally are transferred to the remote side. You
       cannot specify any <ref> if you use this flag.

       Without --all and without any <ref>, the heads that exist both on the local side and on
       the remote side are updated.

       When one or more <ref> are specified explicitly (whether on the command line or via
       --stdin), it can be either a single pattern, or a pair of such patterns separated by a
       colon ":" (this means that a ref name cannot have a colon in it). A single pattern <name>
       is just shorthand for <name>:<name>.

       Each pattern pair consists of the source side (before the colon) and the destination side
       (after the colon). The ref to be pushed is determined by finding a match that matches the
       source side, and where it is pushed is determined by using the destination side. The rules
       used to match a ref are the same rules used by git rev-parse to resolve a symbolic ref
       name. See git-rev-parse(1).

       •   It is an error if <src> does not match exactly one of the local refs.

       •   It is an error if <dst> matches more than one remote ref.

       •   If <dst> does not match any remote ref, either

           •   it has to start with "refs/"; <dst> is used as the destination literally in this
               case.

           •   <src> == <dst> and the ref that matched the <src> must not exist in the set of
               remote refs; the ref matched <src> locally is used as the name of the destination.

       Without --force, the <src> ref is stored at the remote only if <dst> does not exist, or
       <dst> is a proper subset (i.e. an ancestor) of <src>. This check, known as the
       "fast-forward check", is performed to avoid accidentally overwriting the remote ref and
       losing other people’s commits from there.

       With --force, the fast-forward check is disabled for all refs.

       Optionally, a <ref> parameter can be prefixed with a plus + sign to disable the
       fast-forward check only on that ref.
