Hi Anonymous Monk,
Has previously mentioned, it is a lot better to use modules like File::Find or File::Find::Rule and the likes to do what you wanted, than "re-invent", while there is no improvement to it.
However, if you must do that with opendir then something like this can help: 

use warnings;
use strict;

scandir( $ARGV[0] ); ## where to look from CLI

sub scandir {
    my ($file) = @_;
    if ( -d $file ) {
    print $file,$/;  ## print directory name
        opendir my $dh, $file or die "can't open directory: $!";
        while ( readdir($dh) ) {
            chomp;
            next if $_ eq '.' or $_ eq '..';
            print "\t", $_, $/ if /\.pl$/;   ## print *.pl files
            scandir("$file/$_");             ## check sub-directory...
        }
    }
}

Moreover, this has been done in perlmonks, times and again, so search is your friend. Please use it.
Hope this helps.

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
