How to update forked GitHub repository?

Nov 7, 2014

When you fork GitHub repository, you usually want to have your fork up to date with the original repository. You can update your fork in a few easy steps. Just look at the following example of the Git commands:

Add the remote, call it upstream:

git remote add upstream https://github.com/whoever/whatever.git

Fetch all the branches of that remote into remote-tracking branches, such as upstream/master:

git fetch upstream

Make sure that you’re on your master branch:

git checkout master

Rewrite your master branch so that any commits of yours that aren’t already in upstream/master are replayed on top of that other branch:

git rebase upstream/master
