I'm trying to write a script that will find all files with a specific extension (.hhc in my case) under the current directory. I have some basic code working, but it's not quite what I want and I'm not sure where to go from here. I'm not having much luck with the documentation or Cookbook examples.

Here's the code so far... 

use strict;
use File::Find;
use Cwd;

# BEGIN MAIN
$, = "\n";
print &getFileList;
# END MAIN

sub getFileList {
   my @fileList = ();        # list for matching files
   find(\&findFilter, ".");  # populates the list
   return @fileList;

   sub findFilter {
      if ( /\.hhc$/ ) {  # only push matching filenames
         my $curDir = cwd;
         my $fileName = $curDir . $_;
         push @fileList, $fileName;
      }
      return;
   }
}

Here are my questions and issues:

  1. I'm getting a warning about using @fileList in the sub-subroutine. I know that's bad form, but I couldn't figure out a better way to do this. Is there a better way?
  2. I'd like to extract paths relative to the starting directory. I tried to do this by passing cwd from getFileList to findFilter. However, whenever I pass parameters to fileFilter, it seems to lose the file from $_. Is there a way to pass arguments into fileFilter?

I had to do a lot of digging to get enough information to get this far and really appreciate any help you can offer. I'm also hoping this can serve as a useful example in case anyone else is trying to do the same thing. For example, this can also be a good way to create an MP3 playlist.

Thanks for your help everyone.
