Oh, now I understand _why_ backslashing the dashes worked. When your email arrived I was still trying to figure out why echo hello | tr aeiou '\-\-\-\-\-' correctly converted the e and o into dashes. Because tr must have a way for the user to escape the range notation. I don't use tr very often. -brandon
