If I don't ask for a long listing, don't give me one." The reason I say it doesn't make sense is that you shouldn't be asking for a long listing with ls -l if you want numeric ids, you should be using ls -n. Instead of your alias, you should just be using ls -n where you'd otherwise use ls -l. > > As far as I'm concerned, we should _not_ be following the OpenGroup > spec's mandate on this issue.
