I keep idly thinking about getting the last one. I have the 4.3 and 4.4 ones. I'm not sure that I'd find it useful, however. I wouldn't be surprised if it misses out stuff that one can see from the FreeBSD version control. For example: It's fairly well recorded that FreeBSD switched to Mewburn rc, which it got from NetBSD, in 2002. But what isn't so well recorded, that one can only really find out from the version control history, is that this was actually a regression in one aspect, as FreeBSD had some years earlier finally got rid of an old backwards-compatibility mechanism, that Mewburn rc promptly restored. * http://jdebp.info/FGA/rc.local-is-history.html http://jdebp.info/FGA/rc.local-is-history.html One of the interesting things about FreeBSD et al. is that one can reach back decades in version control and look at this stuff. Another example: Linux people often talk about BSD-style options to their "ps" command. But they actually aren't, and BSD has not documented any such things for the entire lifetime of any "ps" command on Linux. Inspecting BSD version control history one can find where the BSD "ps" switched to getopt(3) and changed its manual, and it was in 1990, a year before Linux even existed.

BSD-style is more "anti-SVR4" style, but you also need to remember that everyone working on linux ps in 1991 had years of experience with BSD 4.3 and SunOS 4; the post-reno liberated BSDs (386, Free, Net, and a dozen others that only lasted a year or two) aren't really relevant to that use of the term.

  > BSD-style is more "anti-SVR4" style Sure, but I'd say even more that SVR4 was the anti-BSD. AT&T should have accepted that BSD rocked and adopted it.

  I don't need to have false memory syndrome, thank you. (-: Michael K. Johnson was an undergraduate at St. Olaf College at the time, simply not old enough to have had "years of experience" with commercial Unices. The reality is that this was not written by a bunch of old hands with tonnes of professional Unix experience. Branko Lankester was at the University of Amsterdam.
