What's Your Command Line Judo?
lousyd asks: "We all have our CLI amor. That two- or three-letter command that fiddles our heartstrings. 'mv' is pedestrian, but 'mmv' is so cool. 'cp' can lug bits around all day to no applause, but 'cpio' will excite even the most jaded of command line linguists. 'How perfect!' you exclaim. So what's your poison? What turns you on? What little known command performs just the right function for you?"
with of course! What you can't type a filename on your shell and have the most likely program you want to use it pop up? Reeks to be you!
