Basic Linux Administration via the Command Line

Abstract

The Linux operating system was built to be an open source clone of a series of older operating systems, but primarily of Unix, a multiuser computer operating system that was built by AT&T during the 1970s. At that point in computer history, the desktop powerhouse that we have today was unknown – all computing took place on a central computer system that you would connect to using a "dumb" terminal, a keyboard and monitor that was connected to the central computer, either directly or through some form of early networking. You'd log in and issue commands, and they would be executed off in the distance – very similar to how you'll be using your VPS today!
