From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I've been reading this for a few weeks now.
There's a section talking a bit about the history of unix that I quite liked. I'm young and don't know the whole story. According to this handbook, unix was used and taught in universities, so when students went out into the world they preferred unix systems. As a result, tons of companies started offering their own versions of unix touting portability with the other unixes but with their own differentiating extensions which sort of contradicts the claim of portability. People would write for one system and frustratingly find that their software doesn't work on a different vendor. I'm curious where linux fits into the story. This must have been before linux because the handbook makes no mention of it. Did linux and its free software license immediately kill off these other unixes? How much role did copyleft play?
That was the Unix wars of the ‘80s.
Linux started in ‘92 as a hobby project to create a x86 desktop Unix clone. Most Unices were tied to expensive proprietary hardware which most people couldn’t afford, but x86 equipment was fairly common.
There was 386BSD project which had the objective of porting BSD Unix to x86, but they were sued by AT&T. In the end, AT&T was using more BSD code then BSD was using Unix code.
The lawsuit chilled use of BSD code, and a young CS students decide to write a kernel from scratch rather then fork a BSD.
About the same time Linux was first released, IBM was looking for a Unix-like OS to sell on its x86 servers. The idea was, companies would get started on the low cost x86 servers and graduate to the expensive Power AIX servers. Linux fit the requirements, and it was under the GPL which meant competitors would have to release any changes they distributed to clients as a bonus.
Linux did not immediately kill the propriety Unixes. It wasn’t until after the dot com bubble burst (~2000) that Linux really started taking market share. The tech companies needed to shed expenses, and an easy way was to ditch the expensive Sun equipment running Solaris in favor of commodity x86 running Linux.
The GPL played a role since it meant people distributing Linux needed to release their changes. Linux distros can be fairly different though, so I’m not sure how much of a part it played.
I had a brief opportunity to play around with an AT&T workstation running unix, more like a 386 than any sun/sgi machine that costed as 2 new sportscars. It had a very brief life, despite of the quality of the box, it was pretty useless. Slow as hell windows 95 would run circles around it.
Then out comes DEC/Alpha with Dec's unix, was it ultrix? And in those machines later windows NT was also ported, so it was a testbed between the two worlds. Then RHat CDs rained on us
@jollyrogue @eah
Wikipedia says Ultrix was VAX, and OSF/1 and Tru64 Unix were Alpha.
I am almost certain the first system alpha was ported to was ultrix, those other ones didn't exist yet. Probably developed for alpha, but on its pre-release demo I saw it was ultrix. Sometimes I confused ultrix with sgi/irix
