git remote -v
The result is something like:
origin email@example.com:jiahaoliuliu/android-actionbar.git (fetch)
origin firstname.lastname@example.org:jiahaoliuliu/android-actionbar.git (push)
To change it, type:
git remote set-url origin NewUrlForRemoteRepository
Note: Ater you have changed the url of the remote repository, the first time you do anything with the repository, it is possible you will see a warning message about a new key to trust. This is absolutely normal because you might have changed the server and the new server has a new key.
Note2: The url of the remote repository is saved inside the file .git/config of your repository. You might want to changed manually, but it is not encouraged by the author.
