git‐send‐pack − Push objects over Git protocol to another
repository



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




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.



     −−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. What this









                             ‐2‐


     means is 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.



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

With −−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 pattern separated by a colon ":"
(this means that a ref name cannot have a colon in it). A
single pattern <name> is just a 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
     refs.

 •   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
"fast−forward check", is performed in order to avoid
accidentally overwriting the remote ref and lose other
peoples’ 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.
