Hi ww,

I don't know whether I understand you right. I understood the question the following: From this typical first line of an ifconfig output, the OP wants all entries which are NOT aliased entries. When I let run this script:

#!/usr/bin/env perl
use strict;
use warnings;
use 5.010;

use Data::Dumper;

my @arry = (
    'bond0.2 Link encap:Ethernet',
    'bond4.3:6 Link encap:Ethernet',
    'bond3 Link encap:Ethernet',
    'bond5:0 Link encap:Ethernet',
    'bond1.5:2 Link encap:Ethernet',
    'bond2.6 Link encap:Ethernet'
);

foreach (@arry) {
    if(/^([\w\.]+)\s+Link.*$/) {
        printf "Array item: %-30s\tmatch: %s\n", $_, $1;
    }
}

I get all the "non aliased" lines.

What do you mean is wrong? (I'm pretty sure I can't break the language barrier today.)

UPDATE: After an off thread talk to ww I understand now that the regex presented by ww and Bloodnok fullfills precisely the formulated pattern matching request of snk. So, besides giving the hint for the right way to react on a match the regex should also be corrected to fullfil the request made, even when the result in this example matches the expectations of snk.
