Restart Machine

[ShosMeister]

The "on successful completion" you are referring to is under the "Advanced" tab correct? I managed to find this, but, not sure where to put it:

Close down the system at a given time.
Shutdown provides an automated shutdown procedure for super-users to nicely notify users when the system is shutting down, saving them from system administrators, hackers, and gurus, who would otherwise not bother with such niceties.

SYNTAX
shutdown [-] [-fhkrn] time [warning-message ...]

Options -f Shutdown arranges, in the manner of fastboot(8), for the file sys-
tems not to be checked on reboot.

-h The system is halted at the specified time when shutdown execs
halt(8).

-k Kick every body off. The -k option does not actually halt the sys-
tem, but leaves the system multi-user with logins disabled (for all
but super-user).

-n Prevent the normal sync(2) before stopping.

-r Shutdown execs reboot(8) at the specified time.

time Time is the time at which shutdown will bring the system down and
may be the word now (indicating an immediate shutdown) or specify a
future time in one of two formats: +number, or yymmddhhmm, where
the year, month, and day may be defaulted to the current system
values. The first form brings the system down in number minutes
and the second at the absolute time specified.

warning-message
Any other arguments comprise the warning message that is broadcast
to users currently logged into the system.

- If `-' is supplied as an option, the warning message is read from
the standard input.

Example
shutdown -h now We are going to shut the computer down right now.

Any ideas?
