And of course you can revert changes (also temporarily) at any given time. And that’s not even mentioning the options to store all your work on a remote (central) repository in order to share it with others.

But Git can do so much more. In this post I’ll show you how you can use it to take Unix systems administration to complete new heights. If you ever wondered about some of the advantages which Git has over traditional systems such as Subversion then read on: I’ll be sharing some major examples.
