Hi Monks, I am writing a script to generate a Array of Hashes by reading a input file which contains the text below

I was not able to generate the data for the interface gif0, Can I please know if there is also a better way to parse this file ? 

lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
    options=1203<RXCSUM,TXCSUM,TXSTATUS,SW_TIMESTAMP>
    inet 127.0.0.1 netmask 0xff000000 
    inet6 ::1 prefixlen 128 
    inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1 
    nd6 options=201<PERFORMNUD,DAD>
gif0: flags=8010<POINTOPOINT,MULTICAST> mtu 1280
en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
    ether f4:0f:24:29:df:4d 
    inet6 fe80::1cb5:1689:1826:cc7b%en0 prefixlen 64 secured scopeid 0
+x4 
    inet 10.176.85.19 netmask 0xffffff00 broadcast 10.176.85.255
    nd6 options=201<PERFORMNUD,DAD>
    media: autoselect
    status: active
en1: flags=963<UP,BROADCAST,SMART,RUNNING,PROMISC,SIMPLEX> mtu 1500
    options=60<TSO4,TSO6>
    ether 06:00:58:62:a3:00 
    media: autoselect <full-duplex>
    status: inactive
p2p0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 2304
    ether 06:0f:24:29:df:4d 
    media: autoselect
    status: inactive

Below is my code 


#!/usr/bin/perl
use warnings;
use strict;
use Data::Dumper;

my @AoH;
my $rec;
my $flag = 0;
open my $fh, '<', 'interface.txt' or die;
while (<$fh>) {
    chomp;
    if (/^(\w+\d{1}):\s+flags=(.*?>)/) {
        $flag = 1;
        $rec = {};
        $rec->{'interface'} = $1;
        $rec->{'flags'} = $2;
    } elsif (/ether\s+(.*$)/) {
        $rec->{'ether'} = $1;
    } elsif (/media:\s+(\w+)/) {
        $rec->{'media'} = $1;
    } elsif (/inet\s+(\w+\.\w+\.\w+\.\w+)/) {
        $rec->{'inet'} = $1;
    }  elsif (/status: (\w+)/) {
        $rec->{'status'} = $1;
    } elsif ($flag) {
        push @AoH, $rec;
        $flag = 0;
    }
}

close($fh);
print Dumper \@AoH;
