Remotes

Source: https://docs.github.com/en/get-started/getting-started-with-git/managing-remote-repositories

List remotes

git remote -v

Change remote URL

git remote set-url origin git@github.com:OWNER/REPOSITORY.git

Add remote

Source: New github repo

Usually when a new repo is created this command is provided, and this is generally the easiest way to add it as no modification is needed just copy and paste.

git remote add origin git@github.com:OWNER/REPOSITORY.git

Clear out remotes that no longer exist

git fetch --prune
