At first I thought File::Find might not be that good for this, because he wants to make a list within each directory of its subdirectories, which at first glance means "looking at" each directory twice: once when you're adding it to its parent directory's list, and then again when File::Find comes across it. But then I thought of this, which is very simple, but has the downside of opening the output file every time it needs to write a line: 

#!/usr/bin/env perl
use Modern::Perl;
use File::Find;

sub w {
    if( -d $_ ){
        open my $out, '>>', 'list' or die $!;
        print $out "$_\n";
        close $out;
    }
}
File::Find::find(\&w, '.');
