If you are looking for the address of the default interface, you can
fetch based on the default route.  This should work on most systems, as
almost all have a default route, and few have more than one.

- get the default route entry:
  ip route list match 0.0.0.0

- get just the device name:
  ip route list match 0.0.0.0 | sed 's/.* dev \([^ ]*\).*/\1/'

- list the address(es) on the default device:
  ip addr list $(ip route list match 0.0.0.0 | sed 's/.* dev \([^ ]*\).*/\1/')
