  Hello.
  
  I think your script sounds interesting, but I'd need some instructions.  
  I'm not too clear about Perl, actually and honestly, I'm clueless.  Pleas 
  be in touch.

Here is some html code which will run the script: (add this to your
home page or wherever...)

    <dt> <a href="/cgi-bin/userpages.cgi"> Users with Home Pages </a>
    <dd> Automatically generated index of User Home Pages</dd>


Theses two files need to be in your cgi-bin directory: (the permissions
*must* match these.)

    1 -rwxr-xr-x   1 www      www           141 Apr 24 14:08 userpages.cgi*
    1 -rwxr-xr-x   1 www      www           736 Apr 24 14:16 userpages.pl*

    % pwd
    /usr/local/src/httpd_1.3/cgi-bin


Here is the "userpages.cgi" shell script which will envoke the perl script
with the input from your systems passwd file: (save this code to a file
called "userpages.cgi" in the cgi-bin directory.)

    #!/bin/sh
    #
    # Script to use userpages.pl to show the users with pages.

    echo Content-type: text/html
    echo

    userpages.pl < /etc/passwd
    	
    echo


This is the "userpages.pl" code: (save this code to a file
called "userpages.cpl" in the cgi-bin directory.)


    #!/usr/bin/perl
    # ^^^^^^^^^^^^^ replace this with the path of perl executable

    # The next several lines contain stuff which would normally be
    #   part of an html doc. (Whatever you like...)
    #   (NOTE: notice the placement of the "\" before embedded quotes,
    #   and the "\n" at the end of each line!)

    print "<body BACKGROUND=\"/avalon/texture.gif\">\n";
    print "<hr>\n";
    print "<img alt=\"Avalon Enterprises Inc\" src=\"/avalon/aeilogo.gif\">\n";
    print "<br>\n";
    print "<hr>\n";
    print "<br>\n";
    
    # This is the "meat" of the code...
    
    print "<HEAD>\n<title>Users with Home Pages</title>\n";
    print "<h3>Users with Home Pages...</h3><p>\n";
    print "<ul>\n";
    
    while(<STDIN>) {
        chop;
        ($login, $pw, $uid, $gid, $gcos, $home, $shell) = split(/:/);
        ($name, $office, $workph, $homeph) = split(/,/, $gcos);
        if (-e "$home/public_html/index.html") {
                print qq!<li><a href="/~$login/">!;
                #print "$login ($name)</a>\n"; }
                print "$name</a>\n"; }
    }

    # Place html code here (in print "...", of course) which you would want
    #   at the end of the page...
    
    print "</ul>\n";

    # End of file.


NOTE: you may want to change this script so that it's run once a day,
with the output going to a "userpages.html" file, if you have a large
number of users.

Hope this helps...

Lance
