How many of these actually output what they say they output when run on a modern variant of UNIX?

Almost none. Early Unix uses a rather informal style to report errors, like those debug messages written by a casual programmer. Nowadays, at least the GNU toolchain uses a more rigorous style to report errors formally. BSD's messages are more concise, but still have more details. e.g, compare %make love Make: Don't know how to make love. Stop. and (shell doesn't matter here, GNU make matters) sh-4.4$ make love make: *** No rule to make target 'love'. Stop. There's still a funny one, though. In the old Unix, we had % ar m God ar: God does not exist But now, $ ar m God ar: creating God

  This still works: # whatis love love: nothing appropriate.

Quite a few if you run *BSD! This is on FreeBSD 12.0-STABLE (and use `csh` as noted in the first line). These still works: % "How poorly would you rate the Unix (so-called) user interface?
