Hi Monks!
I am working on this script to list all .pl and .pm files in a directory and later in all found directories. The code I have works until a given directory given list all files, but I am stuck getting to the file level to look for the Perl modules been used by each file found. I have the sub routine that will do that just having problem in make this code work with what I already have. Here is the code:
#!/usr/bin/perl -w

use strict;
use CGI qw(:header);
use CGI::Carp qw(fatalsToBrowser);
use CGI qw/:standard/;

my $q = new CGI;

my $show = param("show");

#my $input_dir = $ARGV[0] || '.' ;
my $input_dir = "../my_directory";

my $arg_name = $q->param( 'arg_name' ) || ''; #arg must be "files"
my $file_name = $q->param( 'fname' ) || '';  #arg must be a file name 
+found in the directory above


print header();

print "<html>
            <head><title>Directory Tree 4</title>
