Simple list of tun devices?
Hello,
I'm using acustom script to bring up and take down my bridge. For that, I need to know the bridge devices that are currently active for use in a bash for-loop.
I reckon that I could grep and sed the output of ifconfig or brctl show, but that seems very kludgy to me. The tun* devices do not appear in /dev and neither did a grep in all of /proc return any useful result.
So, is there a simple way to tell which tun devices are up at any moment?
Cheers,
~Mik

Was passiert, wenn man einem Therapiepatienten ein asymmetrisches Mandala zum Ausmalen gibt? Wird er dann erst recht wahnsinnig?
