The Evolution of the Unix Time-sharing System Dennis M. Ritchie Bell Laboratories, Murray Hill, NJ, 07974 ABSTRACT This paper presents a brief history of the early development of the Unix operating system. It concentrates on the evolution of the file system, the process-control mechanism, and the idea of pipelined commands.

The UNIX Time-Sharing System. Dennis M. Ritchie and Ken Thompson, Communications of the ACM 1974. Summary. This paper presents the overall design of the early UNIX systems as well as the creators' insider perspectives on the design choices. Key components like the file system, process control scheme, and the shell are also described in great

UNIX is a general-purpose, multi-user, interactive operating system for the Digital Equipment Corporation PDP-1140 and 1145 computers. It offers a number of features seldom found even in larger operating systems, including 1 a hierarchical file system incorporating demountable volumes 2 compatible file, device, and inter-process IO 3 the ability to initiate asynchronous processes
