GIT-REMOTE-EXT(1)		  Git Manual		     GIT-REMOTE-EXT(1)

NAME
       git-remote-ext -	Bridge smart transport to external command.

SYNOPSIS
       git remote add <nick> "ext::<command>[ <arguments>...]"

DESCRIPTION
       This remote helper uses the specified _command_ to connect to a remote
       Git server.

       Data written to stdin of	the specified _command_	is assumed to be sent
       to a git:// server, git-upload-pack, git-receive-pack or
       git-upload-archive (depending on	situation), and	data read from stdout
       of <command> is assumed to be received from the same service.

       Command and arguments are separated by an unescaped space.

       The following sequences have a special meaning:

       '% '
	   Literal space in command or argument.

       %%
	   Literal percent sign.

       %s
	   Replaced with name (receive-pack, upload-pack, or upload-archive)
	   of the service Git wants to invoke.

       %S
	   Replaced with long name (git-receive-pack, git-upload-pack, or
	   git-upload-archive) of the service Git wants	to invoke.

       %G (must	be the first characters	in an argument)
	   This	argument will not be passed to _command_. Instead, it will
	   cause the helper to start by	sending	git:// service requests	to the
	   remote side with the	service	field set to an	appropriate value and
	   the repository field	set to rest of the argument. Default is	not to
	   send	such a request.

	   This	is useful if remote side is git:// server accessed over	some
	   tunnel.

       %V (must	be first characters in argument)
	   This	argument will not be passed to _command_. Instead it sets the
	   vhost field in the git:// service request (to rest of the
	   argument). Default is not to	send vhost in such request (if sent).

ENVIRONMENT VARIABLES
       GIT_TRANSLOOP_DEBUG
	   If set, prints debugging information	about various reads/writes.

ENVIRONMENT VARIABLES PASSED TO	COMMAND
       GIT_EXT_SERVICE
	   Set to long name (git-upload-pack, etc...) of service helper	needs
	   to invoke.

       GIT_EXT_SERVICE_NOPREFIX
	   Set to long name (upload-pack, etc...) of service helper needs to
	   invoke.

EXAMPLES
       This remote helper is transparently used	by Git when you	use commands
       such as "git fetch <URL>", "git clone <URL>", , "git push <URL>"	or
       "git remote add <nick> <URL>", where <URL> begins with ext::. Examples:

       "ext::ssh -i /home/foo/.ssh/somekey user@host.example %S	foo/repo"
	   Like	host.example:foo/repo, but use /home/foo/.ssh/somekey as
	   keypair and user as user on remote side. This avoids	needing	to
	   edit	.ssh/config.

       "ext::socat -t3600 - ABSTRACT-CONNECT:/git-server %G/somerepo"
	   Represents repository with path /somerepo accessible	over git
	   protocol at abstract	namespace address /git-server.

       "ext::git-server-alias foo %G/repo"
	   Represents a	repository with	path /repo accessed using the helper
	   program "git-server-alias foo". The path to the repository and type
	   of request are not passed on	the command line but as	part of	the
	   protocol stream, as usual with git:// protocol.

       "ext::git-server-alias foo %G/repo %Vfoo"
	   Represents a	repository with	path /repo accessed using the helper
	   program "git-server-alias foo". The hostname	for the	remote server
	   passed in the protocol stream will be "foo" (this allows multiple
	   virtual Git servers to share	a link-level address).

       "ext::git-server-alias foo %G/repo% with% spaces	%Vfoo"
	   Represents a	repository with	path /repo with	spaces accessed	using
	   the helper program "git-server-alias	foo". The hostname for the
	   remote server passed	in the protocol	stream will be "foo" (this
	   allows multiple virtual Git servers to share	a link-level address).

       "ext::git-ssl foo.example /bar"
	   Represents a	repository accessed using the helper program "git-ssl
	   foo.example /bar". The type of request can be determined by the
	   helper using	environment variables (see above).
