  14DESCRIPTION
  15-----------
  16Usually you would want to use 'git push', which is a
  17higher-level wrapper of this command, instead. See linkgit:git-push[1].
  18
  19Invokes 'git-receive-pack' on a possibly remote repository, and
  20updates it from the current repository, sending named refs.
  21
  22
  23OPTIONS
  24-------
  25--receive-pack=<git-receive-pack>::
  26        Path to the 'git-receive-pack' program on the remote
  27        end.  Sometimes useful when pushing to a remote
  28        repository over ssh, and you do not have the program in
  29        a directory on the default $PATH.
  30
  31--exec=<git-receive-pack>::
  32        Same as \--receive-pack=<git-receive-pack>.
  33
  34--all::
  35        Instead of explicitly specifying which refs to update,
  36        update all heads that locally exist.
  37
  38--stdin::
  39        Take the list of refs from stdin, one per line. If there
  40        are refs specified on the command line in addition to this
  41        option, then the refs from stdin are processed after those
  42        on the command line.
  43+
  44If '--stateless-rpc' is specified together with this option then
  45the list of refs must be in packet format (pkt-line). Each ref must
  46be in a separate packet, and the list must end with a flush packet.
  47
  48--dry-run::
  49        Do everything except actually send the updates.
  50
  51--force::
  52        Usually, the command refuses to update a remote ref that
  53        is not an ancestor of the local ref used to overwrite it.
  54        This flag disables the check.  What this means is that
  55        the remote repository can lose commits; use it with
  56        care.
  57
  58--verbose::
  59        Run verbosely.
  60
  61--thin::
  62        Send a "thin" pack, which records objects in deltified form based
  63        on objects not included in the pack to reduce network traffic.
  64
  65--atomic::
  66        Use an atomic transaction for updating the refs. If any of the refs
  67        fails to update then the entire push will fail without changing any
  68        refs.
  69
  70<host>::
  71        A remote host to house the repository.  When this
  72        part is specified, 'git-receive-pack' is invoked via
  73        ssh.
  74
  75<directory>::
  76        The repository to update.
  77
  78<ref>...::
  79        The remote refs to update.
  80
  81
  82Specifying the Refs
  83-------------------
  84
  85There are three ways to specify which refs to update on the
  86remote end.
  87
  88With '--all' flag, all refs that exist locally are transferred to
  89the remote side.  You cannot specify any '<ref>' if you use
  90this flag.
  91
  92Without '--all' and without any '<ref>', the heads that exist
  93both on the local side and on the remote side are updated.
  94
  95When one or more '<ref>' are specified explicitly (whether on the
  96command line or via `--stdin`), it can be either a
  97single pattern, or a pair of such pattern separated by a colon
  98":" (this means that a ref name cannot have a colon in it).  A
  99single pattern '<name>' is just a shorthand for '<name>:<name>'.
 100
 101Each pattern pair consists of the source side (before the colon)
 102and the destination side (after the colon).  The ref to be
 103pushed is determined by finding a match that matches the source
 104side, and where it is pushed is determined by using the
 105destination side. The rules used to match a ref are the same
 106rules used by 'git rev-parse' to resolve a symbolic ref
 107name. See linkgit:git-rev-parse[1].
 108
 109 - It is an error if <src> does not match exactly one of the
 110   local refs.
 111
 112 - It is an error if <dst> matches more than one remote refs.
 113
 114 - If <dst> does not match any remote ref, either
 115
 116   * it has to start with "refs/"; <dst> is used as the
 117     destination literally in this case.
 118
 119   * <src> == <dst> and the ref that matched the <src> must not
 120     exist in the set of remote refs; the ref matched <src>
 121     locally is used as the name of the destination.
 122
 123Without '--force', the <src> ref is stored at the remote only if
 124<dst> does not exist, or <dst> is a proper subset (i.e. an
 125ancestor) of <src>.  This check, known as "fast-forward check",
 126is performed in order to avoid accidentally overwriting the
 127remote ref and lose other peoples' commits from there.
 128
 129With '--force', the fast-forward check is disabled for all refs.
 130
 131Optionally, a <ref> parameter can be prefixed with a plus '+' sign
 132to disable the fast-forward check only on that ref.
