[[:cntrl:]] matches only bytes with values of 0 through 31. [[:print:]] matches, as you say, 31 to 126. [[:^print:]], which is the negation of [[:print:]] (and can also be written as [^[:print:]]) matches 0 through 31 and 126 through 255. No doubt other differences crop up if you get into using locale and utf8. -- Keith C. Ivey <[EMAIL PROTECTED]> Washington, DC
