How do I get this script to work? The goal is to find the directory at the deepest level in the directory tree and print the name of a file, a random file, maybe the first.

find -type d | declare COUNT=-1; declare P=""; while read LINE ; 
do
   echo $LINE
   declare C
   C=$(echo $LINE | cut -c3- | sed "s/\//\n\//g" | grep '/' -c)
   echo $C
   if [ $COUNT -gt $C ]
   then
       let COUNT=$C
       let P=$LINE
       echo "Done"
   fi
done

Better solutions are also welcome but they should be one-liners.
