Try this:
#!/usr/bin/perl
@info = `ifconfig`;
foreach $line(@info){
if ($line =~ /inet addr/){
$line =~ s/(.*)(:)(.*)(\ )(.*)(:)(.*)/\3/;
print $line;
}
}
I'm sure you could do some grep stuff on this as well:
ifconfig | grep inet | sed 's/inet\ addr://' | awk {'print $1'}
Good Luck

Subject: how do the ip of a PPP connection?
i am trying to write a little shell script that will
update my dns on a remote machine every 10 minutes,
using nsupdate. the problem is I need to get the IP
address of my dsl connection, but i can't seem to find
a way to parse the output from ifconfig. my connection
uses PPPOE. i would be very appreciative if one of the
perl gurus would point me in the right direction.
here is the output from ifconfig, the only thing i
need is the inet addr.
ppp0 Link encap:Point-to-Point Protocol
inet addr:138.89.32.190 P-t-P:10.5.1.1
Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MULTICAST
MTU:1492 Metric:1
RX packets:57247 errors:0 dropped:0
overruns:0 frame:0
TX packets:40905 errors:0 dropped:0
overruns:0 carrier:0
collisions:0 txqueuelen:10
