Change upstream branch

git branch --set-upstream-to <remote-name>

This can be useful if you cloned a repository, then decided to fork it to create a PR.

For example, you cloned a Github repository "user/some-repo" locally, then decided to edit something to create a PR. First, create a fork in Github (if you have the Github command line tool, you can use gh repo fork --clone --remote --remote-name fork). This will result in a new repo "yourusername/some-repo". Then run the following inside your working copy:

# add new remote (the fork)
# this will result in 2 remotes, the cloned one and the one added manually
git remote add fork git@github.com:yourusername/some-repo.git
git fetch --all --verbose
git remote -vv

# set upstream branch to the fork
git branch --set-upstream-to fork/master
git branch -vv

# (optional) remove previous remote: git remote remove <remotename>
git remote remove origin # or "upstream" or whatever the name is
