Unix (officially trademarked as UNIX® - the documentation switched from using 'UNIX' to 'Unix' as of V7) is a computer operating system originally developed in the 1970s by a group of AT&T employees at Bell Labs including Ken Thompson, Dennis Ritchie and Douglas McIlroy.
Today's Unix systems are split into various branches, developed over time by AT&T as well as various commercial vendors and non-profit organizations. A number of clones of Unix, which share the interfaces, and 'look and feel', but no code, have also been produced; most notably, Linux.
Notable versions
Versions of relevance for hobbyists include (note that 'Version' in early UNIXes refers to the revision of the 'UNIX Programmer's Manual'; UNIX didn't really have coordinated distros before about V6):
- Unix "version 0" for PDP-7
- UNIX V1 - The first version of UNIX that has been recently made to run on the PDP-11
- UNIX V3 - The first version with pipes
- UNIX V4 - The first version with the kernel written in C
- UNIX V5 - The first version with complete source and binaries available
- UNIX V6 - The first widely distributed version; the last before branches started to appear
- Unix V7 - One of the most complete, and the last generally available and PDP-11 version of Research UNIX
- Unix/32V - A port of Seventh Edition to the VAX-11/780
Unix then went commercial and was sold, in a number of releases. (Below is an early ad for AT&T UNIX.)
CSRG releases
Meanwhile the Computer Systems Research Group kept on releasing newer BSD UNIX's, mostly for the VAX, derived from 32V. These had wide distribution, and tremendous impact; they were a major step in UNIX's road to its current ubiguity.
Descended from there are several popular versions:
- FreeBSD focuses on providing a system geared towards a single user.
- NetBSD will run on a variety of 32-bit older systems from the VAX to the Amiga.
- OpenBSD derived from the NetBSD project will run on all kinds of systems.
