Well, stdin sort of tends to happen automatically. For instance, this would also take stdin and pipe it to tr: #! /bin/sh tr [A-Z] [a-z] If you need to send stdin straight to a file, then 'cat > filename' is the easiest way to do it, though; trying to use just '> filename' there will truncate 'filename' to a zero-length file. -- Colin Watson [EMAIL PROTECTED]
