sed deserves a lot of love, I still prefer it for a lot of command-line munging, greps everywhere, bit of awk thrown in. That despite the fact that (say) perl -pe might do a more comprehensive or efficient job as basically a drop-in replacement with benefits. Does/should a UNIX course nowadays bother training up students on these microprogramming languages if they're almost certainly going to have perl or python available anyway? They only marginally fit into the UNIX philosophy, so is it just their old-school cred that keeps them around?
