Grep or Tail in shell script
Hi,
I am writing a shell script that checks catalina logs on a production system and mails me if it detects errors.
It greps the logs for known errors which i have defined as variables.
The problem is the logs are huge, approx 30,000 before they rotate.
So I am forced to use grep instead of tailing 30,000 lines.
But while testing grep I end up getting re-notified of previous errors that still exist in the logs.
Is there another way of doing this?
