How to get the ESSID of the active wifi network?

[Jonathan Haug <jonathanhaug wolke7 net>]

Hi there,

I'm looking for a bash command to get the ESSID of the current network
via d-bus.

I tried

dbus-send --system --dest=org.freedesktop.NetworkManager
--print-reply /org/freedesktop/NetworkManager/Devices/eth1
org.freedesktop.NetworkManager.getActiveNetwork

but this one seems a bit outdate. Im using Network Manager 0.8.1.

Any help for me?

Thanks in advance 

Jonathan
