Is there a way to determine if my local clone is a fork of some github repo?

More specifically, how do I tell if the origin of the repo on disk is a fork of some repo? I am thinking that it should be some API call, but I am not sure. Can I rely on "remote.upstream.url"?

Solution

  • You could use the GitHub API for Repositories to get a specific repo

    GET /repos/:owner/:repo

    (you can use a curl call from command line)

    The JSON answer will include a "fork" field: value true or false.

    Another approach, using the GitHub CLI gh repo view command:

    gh repo view VonC/git-cred --json isFork
{
  "isFork": false
}
