[net.unix] differences in UNIX versions

brad@umcp-cs.UUCP (04/23/84)

Can someone please tell me the differences (both internal and visible to the
user) between v7, 4.1bsd, 4.2bsd, System III and System V?

	Uh, y'know, there's only several thousand cases to be described
across five different versions here...you could have asked for v6 and 2.8BSD
to be included as well...

	Seriously, why not do a little research yourself, rather than asking
the net what amounts to an "unanswerable" question?  Why not read the 
documentation available with the different Unix versions, and the published
papers?

	And why am I posting this, not mailing it?  I, for one, am somewhat 
tired of reading posted queries that could have been answered with 5 minutes 
research in (a) the Unix manuals (b) the library's ACM/IEEE publications or 
(c) the local guru's office.

A list of all the differences between 7th Ed., 4.1BSD, 4.2BSD, Sys. III,
and Sys. V UNIXes would fill a book.  The only simple one is that very
little user-visible change occurred from UNIX System III to System V,
except by adding upward-compatible extensions (the main visible change
that was incompatible was in what uname() returned).  If you have
specific requirements, feel free to ask them, but a list of all
differences seems pretty useless since there are so many.
