Github Usage

Change the repository URL of local working copy:

View the current origin URL:
$ git remote -v
$ git remote set-url origin https://github.com/<user>/<repo>.git

If you try to access the repository (clone, push, ...etc) via HTTP/HTTPS, the following error occurred:

error: The requested URL returned error: 403 while accessing https://github.com/user/repo.git/info/refs
fatal: HTTP request failed

Use SSH (get the URL from the repository):
$ git remote set-url origin git@github.com:<user>/<repo>.git



Connecting over SSH
If you clone with SSH, you must generate SSH keys on each computer you use to push or pull from GitHub.

Note: you can use the ~/.ssh/config to setup the SSH authentication instead of ssh-agent
