How to find VERSION of UNIX OS

This works fine under ULTRIX -- if your ULTRIX is up-to-date!  Some of
our workstations are, others aren't, which made it easy to check on this
and under 4.1 (and presumably 4.0) uname works as expected.  It also
works on my PC and as my MKS toolkit manual notes uname comes to us
from the AT&T flavor of UNIX (which makes SunOS a bit of a mystery -- I
thought it was really AT&Sun but I don't have a Sun handy).  The toolkit
manual also points out that uname conforms to POSIX.2 as well as the
X/OPEN Portability Guide so we should see it VMS Real Soon Now!

The direction most UNIXen are headed in is towards a merging of the
best of System V and BSD which is what the standards efforts end up
formalizing.  As another example, ULTRIX 4.0 was where the Korn shell
(the only shell game worth playing...:-) popped up.  I don't think it
came with System V by default until release 4; it's the only shell that
comes with the MKS toolkit although you can always continue to use
COMMAND.COM on the PC if you want...;-)
