If I have a subdirectory within a subdirectory - and they have the same name - my code seems to think that it changed into that directory, but in truth it starts from scratch in the former directory.

File::Find changes directories for you (unless you tell it not to) and is very easy to use. Here's the basic shell of how to use it.

use strict;
use File::Find;

my $root_dir = '/temp';

find(\&wanted, $root_dir);

sub wanted
{
    if ( -d )
    {
        # you've been 'chdir'ed to this directory
        print "Directory: $_\n";
    }
    else
    {
        # not a directory. do as you will
    }
}
