Why was this done in v7 unix and why wasn't it thrown out? 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... -- Dave --1483753691-1897193071-1583301836=:64345--
