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”
They’re more unix like than anything else in widespread use.

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