Repo on Github that I want to contribute to: https://github.com/whoever/whatever.git
My fork of that repo on github: email@example.com:myself/whatever.git
Over time the upstream repo is updated but my fork on github does not automatically get those updates. To push the latest changes from https://github.com/whoever/whatever.git to firstname.lastname@example.org:myself/whatever.git follows these steps.
Clone our repository:
git clone email@example.com:myself/whatever.git cd whatever
Add the upstream repo as a remote, and call it upstream:
git remote add upstream https://github.com/whoever/whatever.git
Get all the branches of the upstream repo into remote-tracking branches. These branches will be named upstream/master, upstream/some-feature, etc.
git fetch upstream
Now replay all of the upstream’s commits from the master branch against ours:
git checkout master git rebase upstream/master git push
