This works in bash. You might have to change the $(foobar) to `foobar`
to make it work in csh or sh. Don't remmeber right now.
CUURENTIP=$(ifconfig | grep --after-context=1 "$INTERFACE" | sed -n 's/.*addr:\([^
]*\).*/\1/p')
CURRENTDEFAULTROUTE=$(route -n| sed -n 's/^0\.0\.0\.0 *\([^ ]*\).*/\1/p')

you're welcome
There's a way to do the first one without grep, but it doesn't come to mind
immeadiately. Sorry for the waste of a process.
sed forever!
