Hi, You've got the basic idea correct. I also wrote some perl to perform a similar function. I also played loose with the rules by making use of global vars to store the matches. Here's my complete code:

#!/usr/bin/perl

#########
#
#  index.pl
#
#  script to create a static HTML file listing all pdfs down
# from a particular directory and provide links to them.

use Template;
use File::Find;
use File::Basename;

# Template Files
my $tmpl_dir            = "/export/home/fredk/docs/index/templates";
my $output_tmpl         = "$tmpl_dir/pdf.tmpl";

# Name of Output file
$outputFile = "pdfs.html";

# Declarations
my @list;

# Extract the path to this script
my $dir = dirname($0);

if ( $ARGV[0] ) { $dir = $ARGV[0]; }  # OR, override it by the cmd lin
+e

# What to search for    CURRENTly hard coded
#my $regex = '.*\.html$';

my $regex = '.*\.pdf$';


# Create a list "@list" containing the path of the pdfs
&find(\&wanted, $dir);

   #
   # Output HTML

   my $vars = {                 # change to be appro. for the form
       'list'             => \@list,
   };

   my $template = Template->new();

   $template->process( $output_tmpl, $vars, $outputFile)
      || &error( $template->error()) ;


exit;

#    The wanted() function does whatever verifications you want.
#    $File::Find::dir contains the current directory name, and $_
#    the current filename within that directory.
#    $File::Find::name contains "$File::Find::dir/$_".  You are
#    chdir()'d to $File::Find::dir when the function is called.
#    The function may set $File::Find::prune to prune the tree.

sub wanted {

   if ( /$regex/ ) { push( @list, $File::Find::name); }
