in thread Perl Directory file extension stats.

Assuming a %stats hash has been declared, the File::Find callback can be as simple as:

sub wanted { return unless -f; /(?<!^)[.]([^.]+)$/; ++$stats{$File::Find::dir}{$1 || ''}; }

That will cause all files without an extension, as well as hidden files without an extension (e.g. .bashrc), to be counted together under a '' key. Everything else will counted under keys without a leading '.', e.g. 'pl', 'txt', 'png', etc.

If counts for individual directories aren't required, that can be simplified even further by just using:

++$stats{$1 || ''};
