Abstract: This chapter provides an overview of UNIX operating system. UNIX is offered on a wide range of microcomputer and minicomputer systems. UNIX is a disc-based operating system that has become an industry standard for multi-user 16-bit microprocessor systems. UNIX is the world's most popular operating system for multiprogramming time-sharing systems. While CP/M possesses a single directory listing all the names of the files/programs in the system, UNIX allows each user to possess a separate directory, and indeed a user can establish other directory layers. UNIX possesses two editor programs that are used for creating files, for example, high level language programs: (1) ed, a line editor program, and (2) vi, a screen editor program. The vi editor is a much more sophisticated and useful editor than ed.
