Version 7
:Version 7: alt. V7 /vee' se'vn/ n. The first widely distributed version
of Unix
released unsupported by Bell Labs in 1978. The term is used
adjectivally to describe Unix features and programs that date from that
release, and are thus guaranteed to be present and portable in all Unix
versions (this was the standard gauge of portability before the POSIX
and IEEE 1003 standards). Note that this usage does _not_ derive from
the release being the "seventh version of Unix
"; research Unix
at
Bell Labs has traditionally been numbered according to the edition of
the associated documentation. Indeed, only the widely-distributed Sixth
and Seventh Editions are widely known as V[67]; the OS that might today
be known as `V10' is instead known in full as "Tenth Edition Research
Unix" or just "Tenth Edition" for short. For this reason, "V7" is often
read by cognoscenti as "Seventh Edition". See BSD
, Unix
. Some
old-timers impatient with commercialization and kernel bloat still
maintain that V7 was the Last True Unix.
