What is UNIX?

UNIX is a computer operating system, first released in 1971.

Development on UNIX began in the late 1960s by a group of AT&T Bell Labs employees.

UNIX is a multi-user, multi-tasking operating system, known for its versatility and portability.

It is also known for its use of a command-line interface and its adherence to a set of strict design principles, such as the use of plain text files and the separation of functionality into small, modular programs that can be combined to perform complex tasks.

UNIX has many benefits, some of which include:

The term "nix" is shorthand often used to refer to operating systems that are based on the UNIX operating system.

It is a play on the word "Unix" and is used as a generic term to refer to any operating system that is based on the UNIX operating system, such as Linux, macOS, and BSD. The asterisk in "*nix" can stand for any letter, and it's used to indicate that it could be any of the UNIX-like operating systems. This term is used to refer to all those systems as a group, as they share similar design principles, commands, and utilities.
