But, um, Randal has (understandably :-) been doing so much perl he's attributed perl intelligence to sed, which just isn't so. In sed you really have to do this: y/abcdefghijklmnopqrstuvxyz/ABCDEFGHIJKLMNOPQRSTUVXYZ/ And make sure they match up exactly. --tom -- "UNIX was never designed to keep people from doing stupid things, because that policy would also keep them from doing clever things."
