Is there any idea ? how to get the notification.

I'm a bit surprised about your output - how come it containes seven lines "natasha 0" when looping across one single username only? And three lines of those above the header lines? Sure the tmp files are empty when running the script? What be the values of the variables (userexpdate, passexp, exp, expday) during the one loop? Run script with the -x option set, and post output.
