Re: help on ip addr
Hello,
You should do it, maybe with a regex like that:
perl -e '$/=undef; $ips = `ifconfig`; while($ips =~ /(?:^|\n)(\S+)[^\n]
+(?:\n\s[^\n])*\n\s+inet addr:(\S+)/gm) { print $1 is $2\n;}'

Either use `/sbin/ifconfig` or the file /proc/net/arp (or write your own program to do what ifconfig does.)
