This is far too complex for my taste. If you are certain that you will
have all the tools around (/usr /usr/local and so on), then it may be
simpler to use something like:
addr=$( ifconfig lagg0 | perl -ne 'print "$1\n" if (m/^.*inet\s+(\S+)\s.*$/);' )
This seems to work without all the looping/sub in awk:
$ ifconfig lagg0 | perl -ne 'print "$1\n" if (m/^.*inet\s+(\S+)\s.*$/);'
