Because a dot (.) matches \r, the (.+) gobbles up your \r so that the character class that follows can't match it. No backtracking is required, since you use '*' (match zero or more) on your character class. Changing the * to a + should make it work. But there are simpler ways: To strip a trailing \r, the simple s/\r$//; should suffice. You've could also use tr/\r//d; which removes \r's anywhere in the string, not just at the end. -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
