The first known software license was sold to the University of Illinois in 1975. Unix grew quickly in academia, with Berkeley becoming a significant center of activity, given Ken Thompson's sabbatical there in the '70s. Three versions of the BSD branch of Unix ended up as open source: FreeBSD (concentrating on ease-of-installation for PC-type hardware), NetBSD (concentrating on many different CPU architectures), and a variant of NetBSD, OpenBSD (concentrating on security).

"A wide variety of distributions available" is the primary reason people pick GNU/Linux over the competition.

Is unix open source

[87] [88] In some industries, open-source software is the norm. Although Linux is not a direct derivative of UNIX, it was born out of the desire for an open source alternative to UNIX and leverages several BSD components. Today’s Linux distributions originated in the early 1990s with Richard Stallman’s GNU (“GNU’s Not Unix!”) project. Most versions of Unix are, in fact, open source, and openly encourage sharing and development. FreeBSD, OpenBSD, even Apple’s version of Unix, called Darwin, is open source.

You wouldn’t bother to, of course, but you could, and it’d be just as unix as Linux – if you wanted to be ridiculous, you could say it was *more* Unix because OS X is TOG branded Unix(tm)… But if you cares about Open Source Initiative opinion and want to follow it strictly (there are actually few who do it, but if), then even the main and universe sections of repository includes some software, which is not ‘open source’ according to OSI: OpenSSL is a most notable example. 2020-07-07 2019-02-21 For a start, Unix is an operating system that was initially developed in AT&T Bell lab. It’s from UNIX that Linux and its derivates are derived. Linux code was developed by Linux Torvalds in 1991 totally from scratch. Linux is free to download and use.While some enterprise distributions such as RHEL require a paid subscription, most distros remain largely free and opensource.

This is a free ( non-proprietary ) and opensource UNIX flavor that descended from BSD branch of the original UNIX system. FreeBSD is compatible with modern processors such as amd64, Intel x86 processors. It is popular for its speed and stability. You can even run an X windows desktop such as XFCE and KDE.
