I am new to shell scripting, I need to write a korn shell script that will delete user unix account and remove their home directory. detail requirement:
1. a user list that contains tens users. format as: username RealName description.
2. check each user if they have unix account in the server, create a new userlist file that only contain username of those who has valid account
3. check each username from the new userlist if they still have active logon session.
4. list out who still has active session if there is, then exit script with no further action
5. if none of them has active session, then delete user account, tar/gz user's home directory and move to a different folder
6. log all actions to a report file, and append report to a full_log file.
Here is the script I wrote, but I don't know how to add point 4 above, please also help to improve it
