manipulate network state from shell

[Gergely Gábor <elentirmo gilgalad gmail com>]

Hello!

I'd like to ask if there is a way to manipulate the natwork stae (more
exaclty: wether wireless is enabled or not) from shell. My wifi card
lacs th rf_switch button (that is usually an advantage) but i'm not sure
wether is disables radio when i disable wireless in nm-applet, so maybe
i'd use rf_kill too. And binding to a hotkey wold be nice. (to be
handled by acpid)

thx: ggergely
