ABSTRACT
UNIX is a general-purpose, multi-user, interactive operating system for the Digital Equipment Corporation PDP-1 1/40 and 11/45 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 I/O,
3. The ability to initiate asynchronous processes,
4. System command language selectable on a per-user basis,
5. Over 100 subsystems including a dozen languages.
This paper discusses the usage and implementation of the file system and of the user command interface.
