BSD = Unix ?


My apologies if this has been discussed before. I've been reading around here and there about the history of unix, and BSD.. And i'm confused about something

In netbsd's website, it says "netbsed is unix-like OS". And i've also seen the same remarks regarding freebsd in other places. But sn't it "unix" ? not unix like ?

I thought AT&T's unix was forked into netbsd, openbsd, and freebsd, hence, them being actual unixes with open/net bsd still having legal copies of the unix licences (like sco and novell currently)

From what i understand, and i could and probably am wrong, Berkely simply bought the licence from AT&T, and eventually BSD was forked from unix (probably licence issues). (Not sure where Solaris comes in too)..

Linux, on the other hand, is a unix-like OS, created from scratch by Linus coz he wanted a free unix like OS to run on x86 architecure based machines (at first).

Am i right in any way?

Thanks.

if you want to call it unix you have to pay for that, none of the bsds will do that

"Historically, AT&T which developed Unix did not want anyone to give it credit by using "Unix" in the name of a similar system. AT&T did not want this even if the system did use code from Unix, not even if it was 99% Unix. AT&T disliked such credit so strongly that it would threaten to sue you for trademark infringement if you tried to give AT&T credit in that way. This is why each of the various modified versions of Unix (all of them just as proprietary as Unix), produced by various computer companies, had some other name."

Thus "tru64", "AIX", "HP-UX", "BSD", etc.
Unlike the other proprietary unices, BSD became free.
