I just did git init to initialize my folder as Git repository and then added a remote repository using git remote add origin URL. Now I want to remove this git remote add origin and add a new repository git remote add origin new-URL. How can I do it?
Instead of removing and re-adding, you can do this:
git remote set-url origin git://new.url.here
See this question: How to change the URI (URL) for a remote Git repository?
To remove remote use this:
git remote remove origin
