Version 8 Unix
{{Bell Unix}}
Eight Edition Unix, also known as
Version 8 Unix or
V8, was a version of the
Research Unix operating system developed and used internally at
Bell Labs. It was "released" in
February 1985, ran on
VAX hardware, and was a variant of
4.1cBSD with some
System V.2 features (notably the
shell). V8 was the successor to
V7 and the predecessor to
V9.V8 Unix introduced the
STREAMS I/O mechanism, the
/proc filesystem and several other features later incorporated into
System V.V8 also featured a
network file system, which permitted access to other machines' entire filesystem trees. For example, the file
/etc/passwd on
server foovax would be accessible to
client machines as
/n/foovax/etc/passwd.
The Unix Programming Environment was prepared on a VAX-11/750 running a preliminary version of V8 Unix.
