"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.
"What Git Does
"Let's say you are working on creating a website for a customer.
They state what they want, you design it, they review it and make
revisions, rinse, repeat. With each set of revisions from the
customer, the site changes and grows. Later, the customer may say
"I like it better the way it looked last September". Under normal
circumstances, you've got a problem. You may not have all the files
and data from that time, and your code may have changed so much
that reverting back would be difficult or impossible."
