Have you considered 'man sed' ? If printing lines 24 through 48 of a file is all you want, sed may in fact be the better answer. While 'perl' makes the impossible possible, it often does the reverse when your problem is perfectly suited to a smaller tool.. You might want to be more specific in your question. Were you after a one liner to show off to the girls? Something that ran faster than sed? something which forms part of a larger application? Jenda gave excellent examples of one liners, possibly bordering on obfuscation (how many people recognise a bi-stable flip flop when they see one?) I have to admit, I use AWK and SED for one liners more often than perl, since they are just plain fast... HTH Cheers. Dave > > Whatever you like.
