How to update a forked repository to match with the origin repository on Github
When you want to contribute to open source, one of the most important things is understand, forking and branching.
Once you have updated some code and made a pull request, you might not do anything with your forks for a lot of time. So the next time you do something, you will have to update it. But how?
Add an upstream remote
We'll add a remote to our repository called upstream with the follow command:
git remote add upstream https://github.com/OriginalRepo/OriginalProject.git
Make sure to use the link of the origin repository
Now you canverify by running
git remote -v
Fetch branches and commits from upstream
Run the following command in order to fetch all the updated banches and commits from upstream
git fetch upstream
Checkout your fork’s local master
git checkout master
Merge changes from upstream/master into it
git merge upstream/master
Push changes to update your fork master'
git push origin master
Note that you might have a different base branch that master.
That's it.. Have fun!
