If you ever needed a script to suspend your PC such as for Transmission after your torrent completes or to suspend your computer at a certain time of night.
It is gnome-friendly too. Well here it is:
#!/bin/sh dbus-send --system --print-reply --dest="org.freedesktop.UPower" /org/freedesktop/UPower org.freedesktop.UPower.Suspend
Be sure to make the file executable, you can do this by:
chmod +x yourScript
