I seem to recall that "sort -r" was in V6, or perhaps that was one of the
programs I'd back-ported from V7 (being stuck with 11/40-class boxes).
And speaking of "tac" (which I never saw), I couldn't think of a single
use for "rev" (although no doubt I'll now get told). Mind you, you get
some amusing output with the "man" command because of the way that the
underlining works...

These go all
the way back to v7 unix, where ls has an option to
reverse the sort order (which could have been done by passing the
output to tac).
Good point. Why was this done in v7 unix and why wasn't it thrown out?
