Use Recursion. I built the following script to recurse through my mp3 directories to build a playlist. I use this on Win32 primarily, but it works on linux/unix too. Just specify the separator on the command line when you run it. 


#!/usr/bin/perl

use MP3::Info;

$dHandle = 'dh00';
my $startDir = shift || '.';
my $separator = shift || '\\';

parseDir($startDir);

sub parseDir
{
    my $currentDir = shift || return;
    my $dirHandle = $dHandle++;
    opendir($dirHandle, $currentDir) or die "Coudln't open directory $
+startDir.\n";

    while (my $filename = readdir ($dirHandle))
    {
        next if ($filename =~ /^\./); # go to next filename if we have
+ a special file (i.e. . or ..)
                # if we find a directory, parse it by calling the pars
+eDir again ( Recursion ).
        if( -d "$currentDir$separator$filename" )
        {
            parseDir("$currentDir$separator$filename");
        }
        elsif($filename =~ /mp3/i)
        {
            my $mp3 = new MP3::Info "$currentDir$separator$filename";
            unless ($mp3 == undef)
            {
                print "$currentDir$separator$filename\n";
            }
        }
    }
    closedir($dirHandle);
}
        
exit(0);

Notice the line: $dHandle = 'dh00'; This variable gets incremented and the subsequent value value gets used as the directory handle in the current iteration.

Let me know if you have more questions about this.
