Shutdown the Linux server if no one is using the server
Hi All,

I want to shutdown the server if no one is actualy using it. Its a linux server.

I thought of sending a msg on users terminal for those who all are logged in and expecting a input from them.

If they will reply system should not get shutdown else it should not.

Can any one help me on this. How can i implement this using Shell scripting.

Thanks in advance.
