Synchronizing a local Git repository with a remote one

Question

I want to synchronize my local repository with a remote one so that my local repository becomes a 100% copy of the remote one - meaning that if certain files differ in these

Answer 1

Sounds like you want a mirror of the remote repository:

git clone --mirror url://to/remote.git local.git

That command creates a bare repository. If you don't want a bare repository, things get more complicated.
