GIT URLS[[URLS]]
----------------

In general, URLs contain information about the transport protocol, the
address of the remote server, and the path to the repository.
Depending on the transport protocol, some of this information may be
absent.

Git natively supports ssh, git, http, https, ftp, ftps, and rsync
protocols. The following syntaxes may be used with them:

- ssh://{startsb}user@{endsb}host.xz{startsb}:port{endsb}/path/to/repo.git/
- git://host.xz{startsb}:port{endsb}/path/to/repo.git/
- http{startsb}s{endsb}://host.xz{startsb}:port{endsb}/path/to/repo.git/
- ftp{startsb}s{endsb}://host.xz{startsb}:port{endsb}/path/to/repo.git/
- rsync://host.xz/path/to/repo.git/

An alternative scp-like syntax may also be used with the ssh protocol:

- {startsb}user@{endsb}host.xz:path/to/repo.git/

The ssh and git protocols additionally support ~username expansion:

- ssh://{startsb}user@{endsb}host.xz{startsb}:port{endsb}/~{startsb}user{endsb}/path/to/repo.git/
- git://host.xz{startsb}:port{endsb}/~{startsb}user{endsb}/path/to/repo.git/
- {startsb}user@{endsb}host.xz:/~{startsb}user{endsb}/path/to/repo.git/

For local repositories, also supported by git natively, the following
syntaxes may be used:

- /path/to/repo.git/
- file:///path/to/repo.git/

ifndef::git-clone[]
These two syntaxes are mostly equivalent, except when cloning, when
the former implies --local option. See linkgit:git-clone[1] for
details.
endif::git-clone[]

ifdef::git-clone[]
These two syntaxes are mostly equivalent, except the former implies
--local option.
endif::git-clone[]

When git doesn't know how to handle a certain transport protocol, it
attempts to use the 'remote-<transport>' remote helper, if one
exists. To explicitly request a remote helper, the following syntax
may be used:

- <transport>::<address>

where <address> may be a path, a server and path, or an arbitrary
URL-like string recognized by the specific remote helper being
invoked. See linkgit:git-remote-helpers[1] for details.

If there are a large number of similarly-named remote repositories and
you want to use a different format for them (such that the URLs you
use will be rewritten into URLs that work), you can create a
configuration section of the form:

------------
	[url "<actual url base>"]
		insteadOf = <other url base>
------------

For example, with this:

------------
	[url "git://git.host.xz/"]
		insteadOf = host.xz:/path/to/
		insteadOf = work:
------------

a URL like "work:repo.git" or like "host.xz:/path/to/repo.git" will be
rewritten in any context that takes a URL to be "git://git.host.xz/repo.git".

If you want to rewrite URLs for push only, you can create a
configuration section of the form:

------------
	[url "<actual url base>"]
		pushInsteadOf = <other url base>
------------

For example, with this:

------------
	[url "ssh://example.org/"]
		pushInsteadOf = git://example.org/
------------

a URL like "git://example.org/path/to/repo.git" will be rewritten to
"ssh://example.org/path/to/repo.git" for pushes, but pulls will still
use the original URL.
