[Coco] KIDS REACT TO OLD COMPUTERS

[tonym]

This one's getting good...

Calling *nix commands in OS X as "Linux commands," is like calling tires firestones...

OS X, at least originally I thought, was Mach kernel-based, using the BSD Net/2 stuff, possibly (probably? ) later.
Don't know if it was FreeBSD, as that was x86-only, and Apple wasn't even near an x86 platform yet. The Mach 3.0 kernel came from
CMU, the BSD maybe from some of the Utah flux stuff and/or the Net/2. However, most sites note that the Mac OS X kernel is NOT a true Mach 3.0 microkernel.

I watched this whole Mach/BSD flux thing, because I was into it back then, with the experimental kernels, and I still have alot of the old cs.utah.edu BSD Lites,
and the Mach kernels stuff on CD somewhere archived.

Bill,

Calling those "linux commands" is fightin' words in some circles. :-) Many
of the command line tools that ship with OS X have significant history
that predates Linux. Aqua is one small part of OS X, and is really just
the name of the GUI "theme".

OS X no longer ships with an X server, although Apple makes it relatively
easy to download and install. Again, X11 has history that predates Linux
by some years. X dates from '84, I believe, and the initial release of
Linux was '91.
