GIT-RECEIVE-PACK(1)               Git Manual               GIT-RECEIVE-PACK(1)

NAME
       git-receive-pack - Receive what is pushed into the repository
SYNOPSIS
       git-receive-pack <directory>

DESCRIPTION
       Invoked by git send-pack and updates the repository with the
       information fed from the remote end.
       This command is usually not invoked directly by the end user. The UI
       for the protocol is on the git send-pack side, and the program pair is
       meant to be used to push updates to remote repository. For pull
       operations, see git-fetch-pack(1).
       The command allows for creation and fast-forwarding of sha1 refs
       (heads/tags) on the remote end (strictly speaking, it is the local end
       git-receive-pack runs, but to the user who is sitting at the send-pack
       end, it is updating the remote. Confused?)
       There are other real-world examples of using update and post-update
       hooks found in the Documentation/howto directory.
       git-receive-pack honours the receive.denyNonFastForwards config option,
       which tells it if updates to a ref should be denied if they are not
       fast-forwards.
OPTIONS
       <directory>
           The repository to sync into.
PRE-RECEIVE HOOK
       Before any ref is updated, if $GIT_DIR/hooks/pre-receive file exists
       and is executable, it will be invoked once with no parameters. The
       standard input of the hook will be one line per ref to be updated:
           sha1-old SP sha1-new SP refname LF
       The refname value is relative to $GIT_DIR; e.g. for the master head
       this is "refs/heads/master". The two sha1 values before each refname
       are the object names for the refname before and after the update. Refs
       to be created will have sha1-old equal to 0{40}, while refs to be
       deleted will have sha1-new equal to 0{40}, otherwise sha1-old and
       sha1-new should be valid objects in the repository.
       This hook is called before any refname is updated and before any
       fast-forward checks are performed.
       If the pre-receive hook exits with a non-zero exit status no updates
       will be performed, and the update, post-receive and post-update hooks
       will not be invoked either. This can be useful to quickly bail out if
       the update is not to be supported.
UPDATE HOOK
       Before each ref is updated, if $GIT_DIR/hooks/update file exists and is
       executable, it is invoked once per ref, with three parameters:
           $GIT_DIR/hooks/update refname sha1-old sha1-new
       The refname parameter is relative to $GIT_DIR; e.g. for the master head
       this is "refs/heads/master". The two sha1 arguments are the object
       names for the refname before and after the update. Note that the hook
       is called before the refname is updated, so either sha1-old is 0{40}
       (meaning there is no such ref yet), or it should match what is recorded
       in refname.
       The hook should exit with non-zero status if it wants to disallow
       updating the named ref. Otherwise it should exit with zero.
       Successful execution (a zero exit status) of this hook does not ensure
       the ref will actually be updated, it is only a prerequisite. As such it
       is not a good idea to send notices (e.g. email) from this hook.
       Consider using the post-receive hook instead.
POST-RECEIVE HOOK
       After all refs were updated (or attempted to be updated), if any ref
       update was successful, and if $GIT_DIR/hooks/post-receive file exists
       and is executable, it will be invoked once with no parameters. The
       standard input of the hook will be one line for each successfully
       updated ref:
           sha1-old SP sha1-new SP refname LF
       The refname value is relative to $GIT_DIR; e.g. for the master head
       this is "refs/heads/master". The two sha1 values before each refname
       are the object names for the refname before and after the update. Refs
       that were created will have sha1-old equal to 0{40}, while refs that
       were deleted will have sha1-new equal to 0{40}, otherwise sha1-old and
       sha1-new should be valid objects in the repository.
       Using this hook, it is easy to generate mails describing the updates to
       the repository. This example script sends one mail message per ref
       listing the commits pushed to the repository:
           #!/bin/sh
           # mail out commit update information.
           while read oval nval ref
           do
                   if expr "$oval" : '0*$' >/dev/null
                   then
                           echo "Created a new ref, with the following commits:"
                           git rev-list --pretty "$nval"
                   else
                           echo "New commits:"
                           git rev-list --pretty "$nval" "^$oval"
                   fi |
                   mail -s "Changes to ref $ref" commit-list@mydomain
           done
           exit 0
       The exit code from this hook invocation is ignored, however a non-zero
       exit code will generate an error message.
       Note that it is possible for refname to not have sha1-new when this
       hook runs. This can easily occur if another user modifies the ref after
       it was updated by git-receive-pack, but before the hook was able to
       evaluate it. It is recommended that hooks rely on sha1-new rather than
       the current value of refname.
POST-UPDATE HOOK
       After all other processing, if at least one ref was updated, and if
       $GIT_DIR/hooks/post-update file exists and is executable, then
       post-update will be called with the list of refs that have been
       updated. This can be used to implement any repository wide cleanup
       tasks.
       The exit code from this hook invocation is ignored; the only thing left
       for git-receive-pack to do at that point is to exit itself anyway.
       This hook can be used, for example, to run git update-server-info if
       the repository is packed and is served via a dumb transport.
           #!/bin/sh
           exec git update-server-info
