I use the icon in the upper right corner of GNOME Shell to shut down my system.
Which command is used to shutdown the system?
shutdown -h now
- Something completely different?
dbus-send --system --print-reply --dest=org.freedesktop.login1 /org/freedesktop/login1 "org.freedesktop.login1.Manager.PowerOff" boolean:true

Now read to the systemd/logind wiki http://www.freedesktop.org/wiki/Software/systemd/logind/
