How to move to a fork after cloning

switch-local-git-repo-to-fork.md

If you are like me you find yourself cloning a repo, making some proposed changes and then deciding to later contributing back using the GitHub Flow convention. Below is a set of instructions I've developed for myself on how to deal with this scenario and an explanation of why it matters based on jagregory's gist.

To follow GitHub flow you should really have created a fork initially as a public representation of the forked repository and the clone that instead. My understanding is that the typical setup would have your local repository pointing to your fork as origin and the original forked repository as upstream so that you can use these keywords in other git commands.

1. Clone some repo (you've probably already done this step)

   git clone git@github...some-repo.git

2. Fork their repo on Github

3. In your local, rename your origin remote to upstream

   git remote rename origin upstream

4. Add a new origin

   git remote add origin git@github...my-fork

5. Fetch from new origin

   git fetch origin

6. Set origin master

   git branch --set-upstream master origin/master

   git branch --set-upstream-to origin/master master

7. Push to fork (origin should be able to omitted given step 4)

   git push origin

I added a bunch of clarity, especially to #6, in my fork of your gist here: https://gist.github.com/ElectricRCAircraftGuy/8ca9c04924ac11a50d48c2061d28b090.

Feel free to pull my gist back into yours if you like, since gists don't allow pull requests.

Thanks for your work!

In my case, I had already made a branch on my upstream clone before I had decided to fork. So my step 6, (6b) and 7 had to be a little different, based on https://stackoverflow.com/questions/11619593/how-to-change-the-fork-that-a-repository-is-linked-to:

git branch --set-upstream-to origin/$branch $branch
git remote set-url origin --push git@github...my-fork
git push --set-upstream origin $branch
