I did add -q to grep, but that's just an aesthetic fix, it'll spam less. Are you sure it's not freezing on mail?

Some how the script is not terminating
I really dont know whats wrong ..the script is not terminating

and i am not receiving any mail .I think so that the script is looking for a termination before the command to sent mail


Pls help!

run 'ps aux' in another terminal to see if you can tell what command it's frozen on.
