Git comes up all the time in discussions of Linux, but in our new world of repositories and package managers, many users are still unfamiliar with it. Read on to get started with this powerful version control environment.
Code and version management used to be difficult and risky. Users were never quite sure whether they would keep or lose their last changes when switching to a different development branch. Attempts to merge the results of hours of work could sometimes lead to unexpected results.
Before Git [1] became the de facto standard, CVS [2] was the most widely used version management system. In CVS, all changes must be uploaded to a central server and the user needs a functioning network connection. In addition, CVS only saves the individual changes and never a complete version of the code.
