I have found out another simpler way to do what I wanted

First the script will grep for all the error messages in the log files and save them to a file.
It will compare this file with the list of error messages grepped during the last run. If there are new rows added to the file, they will be emailed else skip.

So basically simple grep and diff commands Smilie

thanks all for the help.. also if there are any better ideas most welcome
