If you’re a Linux user, you’ve likely come across Git at some point, perhaps while trying to download a new program or looking into version control systems like CVS or Subversion. Git is the revision control system created by the Linux kernel’s famous Linus Torvalds due to a lack of satisfaction with existing solutions. The main emphasis in the design was on speed, or more specifically, efficiency. Git addresses many of the shortcomings of previous systems, and does it all in a lot less time.
