Hi !
I need to search the logs for events matching a condition that
occurred today or yesterday. I know how to do a AND but how to do a OR
?

AND
grep "event" | grep today_date

OR
grep "event" | grep today_date OR yesterday_date.......... how ???

With grep, you can't really. Use egrep instead, and you can separate test
strings with |.

I have forced my fingers to learn 'egrep' in place of 'grep' since it is
100% compatabile with grep (as far as I've ever seen), and also ubiquitous.
