I had set up a 2nd remote repository by running this command
git remote set-url origin --push --add <another remote>
When I do a git remote -v
origin https://url1.com/a.git (fetch)
origin https://url2.com/a.git (push)
How can I remove one of the remote repo?
Looking at git remote --help, I see that I can do
git remote remove origin, but would that remove both of them?
What's the best practice to have multiple remote URLs? Should I have set different branch names instead of having 2 origins?
Your situation has only one remote, origin. To change the push value of the remote, without adding a new value, use git remote set-url without --add. To be extra-explicit, you can also specify the URL that you want to replace:
git remote set-url origin --push https://url1.com/a.git https://url2.com/a.git
This replaces your updated url2 with your original url1.
