So, if we want to switch to hyphens instead of the underscores we have been using and want all our old hyphenated file names to revert to dashes, what would the redirect look like using .htaccess to do it? I know how to redirect a single file to the same file with a different name, but it should be possible to redirect all underscored file names to their hyphenated replacements. And I'm not just talking about a file name with one underscore, I have several with 2 or more underscores in the file name.

Next question would be, is there a program that will rename all files containing underscores to file names with hyphens instead?

Thanks,

Jim
