> or something uncommon like zsh By the time our lord and savior zsh appeared on the scene Perl was already at Perl 3. And, to be fair, I do not think many used zsh before 2.1 which was some time 1991 fall and by then the Camel Book was out for half a year or something like that. So the pre-Perl and the we-use-zsh days do not really overlap. When Perl appeared the absolute hotness was the version of Korn shell what later became known as ksh88. https://github.com/weiss/original-bsd/tree/master/local/tool...

Did a bit of digging and found that there used to be a comment for why it was done, but it got removed [0] when they switched to the implementation from Bentley & McIlroy's "engineering a sort function" [1] around 1992.

Yeah, though I would say human readable bytecode, and it is interesting to see that in the actual context. For anyone who's interested, there's a git repository containing a historical reconstruction of the original BSDs. I believe one of the first BSD versions containing sendmail (by Eric Allman) is this one: https://github.com/weiss/original-bsd/blob/bd282c88c1b3c2575... (almost 40 years ago!) Its a little hard to read due to the format, but here's some explanation of the (1983, earliest?) config file that was used back then: https://github.com/weiss/original-bsd/blob/bd282c88c1b3c2575... From what I grasp, it started as an extensive dynamic parser that needed to understand a lot of rules, and I guess with each new RFC and version, the rules needed to be extended too. And the config file could be loaded into a memory image to improve pe

shiftwidth has been in vi for a very long time. It's been in my exrc since I got into BSD in the 1990s, and judging by the earliest commit that's available online[0] it was added even before 1980. [0] https://github.com/weiss/original-bsd/commit/3effe8f62d3c7b5...

Seems this goes back to 1989 :) https://github.com/weiss/original-bsd/commit/0e1066151c90a80...

You know that whoami didn't originate with GNU, right? The GNU coreutils are themselves rewrites of earlier BSD tools. The Rust version AND the GNU whoami.c both look similar to the BSD original https://github.com/weiss/original-bsd/blob/master/old/whoami.... Hell, the rust version is clearly a lot closer to the BSD original than to the GNU clone. Honestly if you're going to have an opinion on this issue, you should try to educate yourself on all of the Unix that predates GNU.

The novel _Man in the High Castle_ references this system, and was supposedly written with reference to it. [No idea about the tv series, doesn't seem possible to get it in the UK] BSD 4.4 had a game in it that I'd guess simulated the yarrow generation. I wasn't able to get it to compile on a modern system. (https://github.com/weiss/original-bsd/tree/master/games/chin...)
