Project on Shutdown/Reboot of Ubuntu System

[divu212007]

In https://wiki.ubuntu.com/IdeaPool i was caught by the following piece of information:
"Shutdown/Reboot from GNOME/KDE/XFCE menu"

When the user selects an action that is going to bring down the machine check if other users are still logged in and display a warning dialog. This kind of check has to be done when action is either of shutdown, reboot, hibernate. "
I have decided to do an academic project on tis matter.If i get a guidence frm any of them it would be vry helpful.i am expecting reply from ur side.

I think there is a feature in UNIX when the system is hutdown all the users logged on to it will get a mail saying that the syatem is going to be shut-down.

Are you trying something similar?

I think you should check the source of the script called "halt.sh" in an Ubuntu system.
