Thanks Pen,

But my requirement is modifying the cron job which is already running there for a ten minutes. I need to tune the script to obtain more accuracy. The earlier script is very huge and they use tail -2000 for each every exception. We have almost 21 exception to catch and they are doing tail -2000 21 times for the same log. I thought of modifiying it awk statement and asking for help. Jim has given a hint to my idea but still i need some clarification on the mailing parts. In your logic if i get two exception i will get same mail not different mail. still i am require your expertise on this.

thanks
