Most people disagree slightly on this question. It all depends on your perspective. If you go by companies that are allowed to use the UNIX copyright, then only IBM AIX and Sun Solaris are UNIX. If you go by the posix specification, then most operating systems can be considered UNIX as many implement portions of the posix specification if not all of it. Even windows NT/2k/XP have a posix subsystem. (not unix though as they don't have a userland remotely close) I used to get real gun ho on the idea that *BSD is older than GNU/Linux. That was false in one sense. The linux kernel is actually older than the *BSD code that all BSDs are based on. The reason is that most of the BSD kernel was rewritten and implemented AFTER the first public linux kernel release. So on one hand only system V implementations contain any original UNIX code. (aside from a small portion that was considered ok during the lawsuit) I'm sure several others will disagree with me, but this is what I've learned from websites and part of an O'reilly book on the history of open source. I forget the exact title. Also, I don't think a true linux fan would consider linux as UNIX. The reason is the title.. GNU/Linux is the proper name and if you lookup what GNU stands for, you'll see my point. :) As for SCO, I don't think they have much claim over linux code. They might not even own the UNIX code as Novell claims. Either way, SCO UNIX was based on Microsoft Unix (Xenix?) so I laugh at the idea anyway. To summarize, it depends how you interpret the *facts*. I don't think anyone really remembers all the details anymore. -----Original Message----- From: owner-freebsd-questions@freebsd.org [mailto:owner-freebsd-questions@freebsd.org] On Behalf Of Grauwmans Steven Sent: Saturday, June 12, 2004 4:07 AM To: freebsd-questions@freebsd.org Subject: What's the big difference between Linux and Unix?? Linux is UNIX, but why is Fedora Core a Linux and FreeBSD a UNIX? I searched on the internet for an answer, but after visiting 10 sites I gave up. If U could please help me, I'm getting confused.
