Help me Extract a MAC Address

leehaggan

Im trying to extract the Mac address from ifconfig eth0

$HWAddr = `ifconfig eth0`;

$HWAddr= m/([0-9a-fA-F]{0,2})[:]?([0-9a-fA-F]{0,2})[:]?([0-9a-fA-F]{0,2})[:]?([0-9a-fA-F]{0,2})[:]?([0-9a-fA-F]{0,2})[:]?([0-9a-fA-F]{0,2})/g;
But being a perl newbie im really struggling, any help much appreciated :)

There are several modules that do this in CPAN. Look in Net::Packet::Utils for starters.

Here is a quick script I chruned out. It could be neatened up a bit, naturally, but should get you where you want to go.

Expand|Select|Wrap|Line Numbers

 #!/usr/bin/perl

$ifconfigin= `/sbin/ifconfig eth0`;

@ifeth = split(/\n/, $ifconfigin);

($junk,$macaddr) = split(/ HWaddr /, $ifeth[0]);

print "$macaddr\n";
