Copied/re-implemented yes but no incorporation of the BSD's it was written from scratch by mainly one man at the start for the most part, Richard Stallman until others joined him in the GNU project these GNU tools were combined with Linus Torvals kernel he started in the early 90s to give us what is called Linux today.Since Linux copied Unix and incorporated parts of BSD Unix, it was similar in operation and popularity.
He didn't copy it. He wrote his own Unix like operating system.Since Linux copied Unix
Not quite sure what you're saying there, as you seem to confuse a few points. Unix started at AT&T, but due to an anti-trust decree, they couldn't sell it. So, they made it available to universities etc., for little more than duplication and shipping costs. A copy wound up at University of California, Berkely, where it was greatly enhanced, utilities created, etc. Bill Joy, who later founded Sun, made a lot of the contributions to this Berkley Software Division (BSD) version of Unix. Berkley was then sued by AT&T but won the suit, so there is now both original AT&T and BSD code in Unix. There were other Unix versions from IBM, DEC, HP and others, but they couldn't call it Unix, even though developed from AT&T/BSD code. Linus Torvalds created Linux, as he couldn't afford to buy a Unix and the one he was using in school, Minux, he considered inadequate. Richard Stallman didn't create BSD, but developed the Hurd/Mach microkernel system. He also created the GPL open source licence. Linux also uses a lot of the GPL utilities. Further, Linux survived a lawsuit from SCO, which was making outrageous claims about owning Unix and everything it touched. SCO tried claiming Linux contained stolen Unix code, but was unable to provide any proof, but certainly produced a lot of nonsense. This was thoroughly covered on the Groklaw web site. The last remnants of that case died a few weeks ago, when a court ruled they had nothing to proceed with.Copied/re-implemented yes but no incorporation of the BSD's it was written from scratch by mainly one man at the start for the most part, Richard Stallman until others joined him in the GNU project these GNU tools were combined with Linus Torvals kernel he started in the early 90s to give us what is called Linux today.
Well, in an earlier post you said "Copied/re-implemented yes but no incorporation of the BSD's it was written from scratch by mainly one man at the start for the most part, Richard Stallman until others joined him"No where did I state RMS created UNIX he after being frustrated with proprietary restrictive nature of the software direction at the time decided to create his own operating system.
BSD Unix no longer contains any AT&T code. In order to remove any remaining restrictions, the AT&T portions were completely rewritten in the 1990s. Some variants are truly open, in that there is no restriction on their use. Companies like Apple and Microsoft have used BSD to create or enhance their own operating systems without any attribution, licenses or royalties.there is now both original AT&T and BSD code in Unix.
I have to wonder about the accuracy of that statement. There were other options, such as FreeBSD and OpenBSD. At the time, I was using FreeBSD and it was a free, very capable Unix operating system. FreeBSD was widely used as a network server on low end PC hardware at the time. It is still regarded as one of the most stable server OS available. FreeBSD's major limitation was hardware support. For example, it did not support ATA drives so SCSI drives were required. That added some extra expense but Torvalds was free to add ATA support (or anything else) to the FreeBSD kernel if he wanted. It took many years before Linux became as mature as FreeBSD.... Torvalds came along with his inability to afford a Unix license
Torvalds was studying the Minix kernel in university, which was created by Prof. Tanenbaum. Torvalds wasn't looking for a kernel to use, he was looking to create his own. The GPL allowed far more freedom than the BSD license. He posted on Usenet that he was starting a new GPL'ed kernel project and people jumped right in. Back then a guy I worked with (in the next office) was one of the first hackers trying (unsuccesfully at the time) to get Linux running on the IBM PS/2's proprietary MCI bus. Someone solved it years later but the poor guy sure pulled his hair out back then trying to write drivers for it with no vendor support.ExDilbert said:I have to wonder about the accuracy of that statement.

Linux was first released in 1991, FreeBSD in 1993 and openBSD in 1995, so the BSDs weren't available when LInus created Linux. At school, he had to use Minix, which he found unsatisfactory and any other *nix was too expensive.There were other options, such as FreeBSD and OpenBSD

Linux survived SCO's bogus lawsuit.I've got to wonder if such a project would even survive in today's legal minefield of lawsuits over questionable software patents.
The software patent lawsuit scenario in the US today is quite a bit different than it was then. It was more difficult to win such a lawsuit then and the number of lawsuits being filed were fewer. Patent filings, patent trolls and the lawsuits they produce have reached epidemic proportions in the US due to a few districts where it is easy to win large awards. Some corporations exist for the sole purpose of buying patents and suing tech companies for alleged patent infringements. Some of the patents they purchase have expired so they are cheap to purchase but allow the awarding of backdated damages under US law.Linux survived SCO's bogus lawsuit.
