If you maintain your own ongoing fork of a project on Github, you will inevitably want to pull in changes from the originator’s repository. Here’s how I usually go about it.
First add the other guy’s repository to your list of remotes:
cd my-fork git remote add other-guy https://github.com/other-guy/other-guys-repo.git
If you were to then list your remotes, you would have something like:
Now it’s just a case of pulling from the relevant branch on their repo, in this case ‘master’:
git pull other-guy master
Hope that saves someone some time.
