Propagating changes from a local repository to another local repository

On the same machine, user A owns a repository and user B owns a c开发者_运维知识库lone of the repository. How do I propagate user A's changes to user B's repository (taking into consideration user permissions)?

Have user A use "git commit" to commit the changes, then have user B do a "git pull". Since the B repo is a clone of A, you can use the auto-generated remote alias "origin" that aliases repo A's location: "git pull origin (branch name)".
