Can someone help me in writing a script for my System Administration class?

Question

)Inactive accounts on a network waste disk space and may become a security risk.
Write an administrative script (to be invoked by root or the cron daemon) that checks for and generates a list of user accounts that have not been accessed within the last 60 days.


2)Write a script for a mult- user system that checks users' disk usage. If a user surpasses the preset limit (100 MB, for example) in him/her /home/username directory, then the script will automatically send him/her a warning e-mail.
The script will use the du and mail commands.
