Assume I've already tried the obvious answers. :-) ifconfig
isn't quite portable. See below for FreeBSD's output
("inet [IP address]") and contrast it with Debian's ("inet
addr [IP address]").
Besides, that's all screen-scraping anyway. I want to be
able to use this in a script, and I'd prefer not to mangle
text to get my interfaces. The functions necessary to get a
list of all my interfaces, and get the IPs for all of them,
are almost certainly system calls. I'm sure there's a Perl
function to extract them.
Any ideas?
