Were dealing in semantics here. From my side its not UNIX unless it has a UNIX code base in it. The GNU applications are not 'UNIX', they are used by 'UNIX'. If the two systems have completely different kernels but both use some of the same apps is it UNIX?

If I could hack windows to act like a UNIX box (shuddering) would it be UNIX? it is posix compliant, uses tcp-ip, and can run many of the GNU toolkit applications on it..

BSD is "based on the original UNIX code, while Linux is its own codebase." Free BSD is based off of the BSD code so while not a direct descendant of UNIX is also contains original UNIX code..

I just believe in giving credit where credit is do. I have seen MS, time after time, reverse engineer soneone else excellent product/idea and then claim it's an MS invention. Kinda pisses me off. Prior to Unix, computer OS's sucked. Unix/C changed the world of OS's and programming. I kinda think Bell Labs should get the Lion share of the credit.

"Were dealing in semantics here", not really, I deal quite a bit at the requirements level. One could argue that defining a project down to the detailed requirement level is most of the work. Once that is done and done well the coding is relatively easy. That is what Linus got from Unix, at very good set of detailed requirement, plus the perfect environment to test (A Unix box). The work real work developing Unix and all the other Unix like OS's was done at Bell Labs.

Once At&t droped the ball a host of others picked it up and ran with it. Sun and Berkly the most notable.
