Version 7
|
|
|
|
/vee sevn/ , 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.
