What’s the general opinion on the BSDs? Are they just Unix-Like (like Linux), or are they really Unix?
Some call them “heritage Unix”, because, although they no longer contain a single line of AT&T code (and haven’t for over 40 years), they were ultimately derived from the original Unix.
This is a bit tongue-in-cheek, because I wonder, if you consider BSD to be “true Unix”, what other “Unix-like” operating system besides Linux kernel-based systems there are. Or are “real” Unices also considered “unix-like”?
As an aside, what about macOS, if you use the command line a lot?
It’s more Unix like than Linux. It’s sticks to the Unix philosophies more than Linux does. MacOS is basically a modded version of FreeBSD with a DE.
macOS is also a certified UNIX according to the Open Group:
All BSD flavours are as far as I know.
Nah, UNIX certification requires paying money and almost all of the BSD spins said “That’s dumb, we barely have money as it is”
Smart choice. I didn’t know that, thought it was free, cuz I think I read somewhere that all were certified… I guess I remembered wrong. It was probably about something esle.
They’re more unix like than anything else in widespread use.

Personally, I consider macOS, BSDs, and Linux real “Unixes”.
