Using 'awk' here is a bit of an overkill. Should the output of 'iwconfig
--version' vary on another disto, or change overtime, it may no longer
be available in field 4, as relied on by the current implementation.
I believe 'sed' offers greater flexibility here in terms of processing
varying output as well as being more light-weight.
Tested on:
Arch Linux
openSuSE 13.2
