Get GitHub API oauth token with curl.

If you're running a non web app on the github api you can simply get the auth token for it (if you have configured in your account under applications of course) by running the following curl command.

% curl -i -u "username:password" \
  https://api.github.com/authorizations \
  -d '{"client_id":"APP_CLIENT_ID", "client_secret":"APP_CLIENT_SECRET"}'

Beware that you'll have to escape some shell sensitive special characters that may be in you password.
