Match regex from right to left?

Question

Is there any way of matching a regex from right to left? What Im looking for is a regex that gets

MODULE WAS INSERTED              EVENT
LOST SIGNAL ON E1/T         


        

Answer 1

Can you do field-oriented processing, rather than a regex? In awk/sh, this would look like:

< $datafile awk '{ print $(NF-3), $(NF-2) }' | column

which seems rather cleaner than specifying a regex.
