How do I show origin url in Git to find the original clone source of a local repo?

You can use the classic git remote -v command, which gives you both fetch and push URLs for your remotes. It’ll look something like:

origin  https://github.com/username/repo-name.git (fetch)
origin  https://github.com/username/repo-name.git (push)

This is the easiest way to spot which fork or upstream repo your local clone came from. It works regardless of whether the project has been updated or changed since.
