Thanks for the training. I appreciate people pointing out my errors, that's how I learn too. I'll blame GMAIL for the mish-mash. I don't have as good a control of it as I would like (sorry). I'm always forgetting about people who put LFs in a file name. That is just so weird, to me. I should remember about the damnable blanks in a file name. They are a PITA to me all the time (I hold MS responsible for this abomination taking hold).
The need for "./[0-9]*' was in a subsequent posting by Krem that the subdirectory names must begin with a digit. Especially thanks for the fix on the "find" with the need to surround the file name extension tests in parentheses. And I do have a tendency, due to ignorance, of putting in unnecessary escapes and using egrep instead of plain grep even if I'm just doing a BRE instead of an ERE.
