The git remote set-url command changes an existing remote repository URL.

This command takes two arguments:

1. An existing remote name. For example, origin or upstream are two common choices.

2. A new URL for the remote. For example, https://github.com/USERNAME/OTHERREPOSITORY.git

So to change the URL of a remote repository you would do something like this:

1. View the existing remote repository:

git remote -v

2. Change the URL of the remote repository:

git remote set-url origin https://github.com/USERNAME/OTHERREPOSITORY.git

3. And you may verify the new remote repository by doing:

git remote -v
