The short answer: The owners of the Unix trademark (www.opengroup.org, IIRC) control who may refer to their OS as "Unix". The've got a suite of tests and specs which include the need to pay them money both to use the tests and the trademark. The specs include what's referred to as "POSIX" and are sorta open. The BSD and Linux OSes attempt to be compatible with most of them. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
