I've not tried to scroodle what you're trying to do,
but expr is integer-only. That's your problem.
When faced with problems that look like this I usually
use awk with a awk script on the command line
mixed in with the regular shell scripting.
Mostly because it's not perl so there's
an upper limit to how crazy the script can get.
