Access interfaces name and information by command line

[Oyabi]

Hi,
Is there a way to show information about interfaces in a file like it's possible for the gateways with /var/run/apinger.status ?
Or maybe there is a command ?

Regards.

it probably is. its best that you specify exactly what you need/want.
some of the regulars might be able to help you out.

Hi,
I want to get IP, interface (em2) and interface name (WAN_BLABLA), packet loss, latency (?), etc.

Regards.
