Po preskumani jednotlivych vypisov som zistil, ze by mohlo univerzalne
fungovat takto:

/sbin/ifconfig eth0 | perl -e 'while(<>){ print $1,"\n" if( /inet/ and /(\d+\.\d+\.\d+\.\d+)/);}'

Pre tych co nemaju radi perl si to mozu prepisat do niecoho ineho.
Ide o pricip:
vypis prveho cisla v tvare c.c.c.c na riadku, kde je slovo inet.
