[Freeswitch-users] Auto-detecting Local IP when no gateway set

[EL]

> /sbin/ifconfig $1 | grep "inet addr" | awk -F: '{print $2}' | awk '{print
> $1}'

To make it a bit less ancient:

========
/bin/ip -o addr show | grep inet | awk '{print $4}' | awk -F/ '{print $1}'

or just for eth0:

/bin/ip -o addr show eth0 | grep inet | awk '{print $4}' | awk -F/ '{print $1}'
========
