Not true. There may be more than one address per interface in each
/etc/ifconfig.xxx file. Also, not every address is an IP address.
Also, the lines that specify IP addresses are not all formatted the
same, and contain more information than just the IP address.
Consistently getting just the IP address out of such a line would be
a pain - you'd need to know how to parse an ifconfig command line, for
all current and future versions of ifconfig.
