There's no need to run any program just to know if a directory is empty. Emacs has primitives which will tell that directly (e.g., file-attributes) and do that faster.
How do you determine that from file-attributes? It is not obvious. You might try to do it from the number of hard links to the directory, which will normally be 2 for an empty directory, since users normally can't create alternate names for a directory. But isn't it possible for root to create them? Then an empty directory could have a link count greater than two. _______________________________________________ Emacs-devel mailing list Emacs-devel@gnu.org http://lists.gnu.org/mailman/listinfo/emacs-devel
