As one of the project leads, I am formally asking you to make dd default to binary behavior. This whole thread was kicked off by someone who was suprised by the current behavior. I don't think there is any reason to force people to read the man page in order to get the behavior that they're used to on UNIX. If you want to make it to text mode when the dd arguments clearly indicate that you're manipulating text, then that would be great. Otherwise, the current and proposed behavior will just annoy me and prevent me from writing portable scripts. I use text mode mounts myself and I do not desire this behavior. So far, that seems to be two for two desiring binmode. cgf -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
