I don't think there is a way to do it inline in the File::Find subroutine without recursion, but if you can wait until the end, I think this should do it:

#!/usr/bin/perl

use strict;
use File::Find;

my %seen;

find( sub { if (-d) { $seen{$File::Find::name}++; delete $seen{$File::
+Find::dir} }; }, '/tmp/a' );
print join "\n", (keys %seen, undef);

This creates a hash key for every directory, and deletes every key that is the same name as the parent. Therefore directories who have no children will never get deleted.
