I have a company GitHub account and I want to back up all of the repositories within, accounting for anything new that might get created for purposes of automation. I was hoping something like this:
git clone email@example.com:company/*.git
I don't think it's possible to do it that way. Your best bet is to find and loop through a list of an Organization's repositories using the API.
git cloneeach of those
It's a little bit of extra work, but it's necessary for GitHub to have proper authentication.
