I return with another question that those skilled in the art might kindly help me with...

I want to recursively scan all the directories and subdirectories from a given starting point. At some point in the future I'm going to do things to the security on all files in the directory - the reason I'm using Perl is that (a) DOS batch is rubbish and (b) CACLS.EXE is rubbish and (C) I need to look at the security before doing the aforementioned things.

But enough natter; here's the subroutine that, at the moment, is intended to print out a recursive listing of the directory tree: 

sub printdir {
  my $item;
  foreach $item(@_) {
    if (-d $item) {
      print "$item\n";
      opendir(SUBDIR, $item) or croak "Can't open directory :$!";
      my @subdir_items = readdir(SUBDIR); #+
      closedir(SUBDIR);                   #+  
      printdir(@subdir_items);            #+
    }
  }
}

At the moment, it simply prints out the very first eligible item, lots of times, with the odd warning about deep recursion.

This nicely printed out the items in a single directory before I added the lines marked with #+.
