Message-ID: <7054@brl-tgr.ARPA> Date: Mon, 7-Jan-85 09:25:10 EST Article-I.D.: brl-tgr.7054 Posted: Mon Jan 7 09:25:10 1985 Date-Received: Tue, 8-Jan-85 05:12:13 EST Sender: news@brl-tgr.ARPA Organization: Ballistic Research Lab Lines: 28 Let's get the nomenclature straight. The version of UNIX that AT&T is actively marketing is called "UNIX System V" (with "Release 2.0" or some such appended for different release levels, and "version 4" or some such appended to that to distinguish between versions for different CPU types and/or structural changes). That is NOT "Version 5", it is "System V". The various editions of UNIX as they were developed by Bell Labs computing science Research staff were called after the edition of the "UNIX Programmer's Manual" that described the system. The first UNIX distributed outside Bell Labs was the "Fifth Edition", the first available for commercial licensing was the "Sixth Edition", and the first relatively portable edition was the "Seventh Edition". The version recently developed for Bell Labs internal use, with a few copies apparently being made available to selected universities, is the "Eighth Edition". These "Editions" are often referred to as "Versions", with the Eighth Edition known as "Research Version 8" or "V8" for short. Although there is considerable commonality between the Research UNIX Editions and AT&T's marketed UNIX System V, there is also considerable difference, especially in network support. The Eighth Edition's character I/O system is different from that in any generally available UNIX and is described in the last article in the BLTJ. Brought to you by Super Global Mega Corp .com
