One easier approach:
use Tie::File;
tie( my @array, 'Tie::File', "/path/to/file" )
or die $!;
my $n = 0;
while ( $n <= $#array ) {
if ( $array[$n] =~ /.*[Oo]rder deny,allow(.*)/ and
$n < $#array and $array[$n+1] =~ /[\Dd]eny from all(.*)/ )
{
$n += 2 and print "\tRequire all denied\n";
next;
}
print $array[$n++],"\n";
}
