Get active interface

Hi,

assuming that a host has only one active (LAN-)interface is there a command
to query its name?

Thanks, Helmut

ifconfig -a, but you might need to parse that if you want to extract the
name. You'll get the loopback interface too.

I thought about a single command showing a single line. No grep, awk,
whatever...
