Linux is Unix and Unix is not a real-time OS. BeOS was a lot closer to
a desktop RTOS but Gassee, being French, was technically bright but
stupid businesswise. So we can blame the French here like always.
Linux is not Unix. If Linux were Unix compliant, Linux could call
itself Unix. The Open Group holds the UNIX System trademark in trust
for the industry. Conformance to the Single UNIX Specification is
measured through a family of test suites. Linix is classed as a
different operating system seperate from Unix.
What is Unix? Is there just one Unix? Is it a BSD release? Is it an
AT&T release?
here are many Unix compliant operating systems. There are more that are
unix like. The distinction is subtle at times and obvious in others. An
obvious example of a unix like os is AIX which is an acronym for Ain't
unIX.
Personally, I figure if it has all the system calls that v7 had, it's
Unix. Others may differ.
There there are the commands, and the return codes from those, etc.
There was a RTOS version of Unix called RTOS-Unix. IIRC that version
was develped at AT&T Unix Systems Laboratories.
Unix systems laboratories???

Yup. USL was sold to Novell. AT&T Computer Systems, wrote some very
large checks to USL as part of the licensing agreement for SVR4. SVR4 was
the first time that Unix had features like a loadable and unloadable
device drivers, 100% streams based networking and serial communications,
as well as other interesting features. Met some very interesting people
at the Labs. One fellow that impressed me the most could view the
disasssembler output and convert that to C in his head. Not sure what
ever happened to Art and his partner Dwayne. That was a long time ago, in
a very far away place. Those were the days of Datakit, IH, Amhdahl, 3B,
and the eventual NCR destruction of a family of products. We figured that
when NCR took over the new company would be named Cash Registers and
Phones.
