Re: newbie - hash

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]);
[download]

although I don't know what the \ that you have there does...

The \ you're both confused about actually creates a reference to the variable it precedes. In the code, it assigns a reference to the array of @user_info[4,5] as the value of the hash. You need to read perldoc perlref. (Pay close attention to how you dereference a reference.)	[reply]
