The coding is fine (TMTOWTDI) - The problem lies with just one line, line 10.
My way to get it working was to modify the first block of code so it says this:
open(USER_LIST, '/etc/passwd') or die "Couldn't open: $!"; while (<USER_LIST>) { @user_info = split /:/, $_; $user_dict{$user_info[0]} = $user_info[4] . " " . $user_info[5]; }

I think the problem is here :
@user_info[4,5]; #same as ($user_info[4],$user_info[5]);
although I don't know what the \ that you have there does...
