FireDog69 has asked for the wisdom of the Perl Monks concerning the following question:

I am very relatively new to the PERL language. So please bear with me. I am creating a site which requires a login via .htaccess. I am trying to figure out how to read the ENV(“$REMOTE_USER”) variable to use the user name within the site.

Here is a small simple piece of script that I have tried which prints nothing at all. 

--------------------------------------------------------
#!c:/www/perl/bin/perl.exe
#-- This Displays errors to browser --#
BEGIN
{
    $|=1;
    print "Content-type: text/html\n\n";
    use CGI::Carp('fatalsToBrowser');
}

$user = $ENV{"REMOTE_USER"};

print "<p>$user</p>";
--------------------------------------------------------

What is wrong?

Thanx,

    The code works, but I thoroughly recommend you use strict and warnings now while you're still fresh and impressionable :) 
    #!c:/www/perl/bin/perl.exe
use strict;
use warnings;
use CGI::Carp('fatalsToBrowser');

$|=1;
print "Content-type: text/html\n\n";

my $user = $ENV{"REMOTE_USER"};

print "<p>$user</p>";

    I don't use Perl on Win32, but my guess is (depending on which Perl you're using maybe) that either:

    • file associations aren't set up for .pl/pm files;
    • the path to Perl is screwy; or
    • your script's name does not end in a valid file extension.

    oh, ps - you might also want to learn the CGI module as well :)

    I second cLive;-)'s suggestion to look at the CGI-module. It lets you do the following: 

    #!c:/www/perl/bin/perl.exe
use strict;
use warnings;
use CGI qw/:standard/;
use CGI::Carp('fatalsToBrowser');

print header(); # instead of putting print "Content-type: text/html\n\
+n";
print remote_user();

    Hope this helps...

    I am very relatively new to the PERL language.

    One important thing to learn is that there is no PERL. Perl is the language, perl is the interpreter.

      /me points to Acme::Inline::PERL... according to the POD: 
      PERL is a programming language for writing CGI applications. It's main
+ strength is that it doesn't have any unnecessary warnings or strictu
+res. It is a direct descendent of Perl, a programming language which 
+was used
mainly by programmers. However, the original language required too muc
+h reading and thinking and so PERL was developed as a language which 
+was more in tune with the requirements of the Internet age.
