What is Unix ?

UNIX is an operating system originally developed in 1969 at the Bell Labs by a group of AT&T employees, Ken Thimpson, Dennis Ritchie and Douglas Mcllroy and has been under constant development ever since. It is a stable, multi-user, multi-tasking portable system for servers, desktops and laptops. Today's UNIX systems are split into various branches developed over time by AT&T as well as commercial vendors and non profit organizations.

UNIX systems also have a graphical user interface (GUI) similar to Microsoft Windows which provides an easy to use environment. However, knowledge about the UNIX commands is required for operations which aren't covered by a graphical program, or for when there is no windows interface available, for example, in a telnet session.

Unix-like operating systems such as Linux and BSD are commonly found.
