Need a geek icon...

My new fav one-liner:

while true ; do clear ; date ; echo ; ls -lh ; REPLY="" ; read -sn 1 -t 1 ; if [ "$REPLY" = "q" ] ; then break ; fi ; done

It'll watch a directories contents (via ls), prefixed with the current time. It'll refresh every second until you hit the 'q' key - or faster if you hit any other key.
