I'm looking to do something which is relatively simple, so I assume there's a way to do it simpler/more elegantly than I am doing it. If that's the case, I could use any assistance to cleanup my code. The goal is to read in the host file from my pc, and comment/uncomment a specific line. The below code works (as long as perl.exe is set to run as an Admin), I am just looking to find if there's a simpler version. 
use strict;

open(my $In, '<', "C:/Windows/System32/drivers/etc/hosts") or die $!;
my @Output = <$In>;
map{if($_ =~ /^(#)?(10\.10\.1\.2.*)/){$_ = $1 eq '#' ? $2 : "#$2";}} @
+Output;
close $In;

open(Out, '>', "C:/Windows/System32/drivers/etc/hosts") or die $!;
print Out @Output;
