git-remote-fd - Man Page

Reflect smart transport stream back to caller


"fd::<infd>[,<outfd>][/<anything>]" (as URL)


This helper uses specified file descriptors to connect to a remote Git server. This is not meant for end users but for programs and scripts calling git fetch, push, or archive.

If only <infd> is given, it is assumed to be a bidirectional socket connected to a remote Git server (git-upload-pack, git-receive-pack, or git-upload-archive). If both <infd> and <outfd> are given, they are assumed to be pipes connected to a remote Git server (<infd> being the inbound pipe and <outfd> being the outbound pipe).

It is assumed that any handshaking procedures have already been completed (such as sending service request for git://) before this helper is started.

<anything> can be any string. It is ignored. It is meant for providing information to the user in the URL in case that URL is displayed in some context.

Environment Variables

git push fd::7,8 master (as URL)
