You misunderstand. The manual warns against the use of digits to pass numerical arguments. This usage exists in some historical cases, e.g. "nice -10" where <10> is the number 10. The use of digits as flags characters, like -4 or -6 to indicate IPv4 or IPv6, is perfectly fine. -- Christian "naddy" Weisgerber [email protected]
