Shell scripts

[ShivKumar_1]

Hi Experts
I am trying to write a script which calculates the difference between the two dates and gives it as the number of days say for Eg: between today 4/18/01 and 3/18/01 its 30 days.
My aim is to monitor the last login time of a user and compare it with the system date and in case its more than 60 days I want to send a alert saying user has been idle. My client runs a NIS environment and he doesnt havee trusted systems. I have tried writing the following script below, can you pl guide me and let me know if its the correct way?

Thnks in advance
Shiv

You would be better posting this query in the HP-UX forum as this forum is meant for hardware queries.
