Hello All,
I'm writing a Perl script for which I'm trying to determine if a certain IP
is bound to a given NIC. I was trying to do it by regex matching the output
of ifconfig as follows:
$ifconfig = `ifconfig`;
if ($ifconfig =~ m/. $IPADDRESS ./) {
execute this code;
}
I got to thinking that this was grossly inefficient, and since it wasn't
working anyway, I started wondering if there is a more efficient way to do
this in Perl with some system functions I didn't know about. I looked
through the sysctl variables and environment variables to no avail. Any ideas?
