Anyway, suppose you have a local git repository that you cloned from some remote repository at, say git://user@dev.foo.com/git/repos/path, and you've been happily pulling, pushing and rebaseing to and from that remote repository. But now you or your team leader have moved that remote repository to a new location, and you'd like to point your repository to the new URL without having to do a full checkout.

What you need to do is change your 'origin' setting. Unfortunately, there's no trivially easy way to do this from the command line in current versions of git. Instead, you edit .git/config in your project root, which may look something like this:

...
[remote "origin"]
url = git://user@dev.foo.com/git/repos/path
fetch = +refs/heads/*:refs/remotes/origin/*
...

or if your 'remote' is actually local:

...
[remote "origin"]
url = /path/to/repos/on/this/machine
fetch = +refs/heads/*:refs/remotes/origin/*
...

All you need to do is edit that file with your favorite editor and change the url = setting to your new location. Assuming the new repository is correctly set up and you have your URL right, you'll be happily pushing and pulling to and from your new remote location.
