Interesting.........
Just read up on that, and yep, OSX is fully POSIX and *Nix compliant,
and is Unix 03 certified on the SUS side,
while no release of Linux has made it to SUS certification as of
now. :)
Cool beans. :)

Not all correct.
OSX -- and it's pure core called Darwin (that lacks some of the GUI
stuff) has a terminal -- I run tcsh for mine, the standard is bash
-- just like your average linux desktop. OSX comes with grep, find,
bc, vi, emacs, du, df, yes, etc etc -- all the random commands that
you expect to find on a *nix/*bsd system. Furthermore, "genetically"
speaking, most of the userland derives directly from FreeBSD. As I
understand it, parts of the kernel (the non-mach parts) were also
derived from the FreeBSD monolithic kernel. The mach kernel was
developed specifically as a microkernel for I believe BSD systems.
So, the userland and the kernel are pretty much pure unix, with some
Apple additions thrown on the top.
Furthermore, somewhat incorrect when you separate unix and nextstep
-- nextstep is ALSO a unix-derived system.
Last, but not least, check out Unix certification:
http://en.wikipedia.org/wiki/Single_UNIX_Specification
OSX is an _official_ unix. You know what's not an official unix--any
version of linux ;-) (so, take that with a grain of salt!)
