I need to add this expiry part in shell script.

timestamp will help you. If you have gnu date or your date command support %s , can use below code:

date -d "2010-05-11" +%s
1273500000

After you get the timestamp, write a if-then-fi to compare the script running date with it.

This does not prevent the script from being run by back dating the system date. You will also need to add a data file that keeps track of the current date and sets a flag when 2010-05-11 occurs so that the script will never run again no matter what the date, or get the current date from a place other than the system that you are running the script on.
