Then the cat example of >the OP doesn't count at all. binmode means there is no extra processing on the fd. It is handled just like linux. Linux doesn't add or subtract any characters when it is doing I/O. You're right, though. The cat example really doesn't provide any useful details. In fact, cat will output in text mode in some cases. The definitive test would be to run the older and newer versions of perl on the newest version of cygwin. If the output using 'binmode' differs between the two then perl is doing something wrong. If it is the same then cygwin is doing something wrong. 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/
