Hey Clive,
You need to prepend the DISPLAY variable as part of the command.
Personally i think zenity looks a whole lot nicer the xmessage, but
that's IMO.
Zenity:
$ at now + 2 minutes <<< 'DISPLAY=:0 zenity --warning --text "Wake Up";'
xmessage:
$ at now + 2 minutes <<< 'DISPLAY=:0 xmessage '"Wake Up"'
The <<< will directly pass the command to be run 'at' without having to
manually empty. Good for scripting :)
Kind Regards,
Dave Walker
