Hi! In Cygwin terminal (bash) I typed: cmp <(echo echo1) <(echo echo2) This does not print anything. Not even with -b. On Linux (Ubuntu 12.04 in VMWare) it reports that the inputs are different. Bug? Or am I missing something? I just updated to latest version of cygwin, to be sure. 32 bit version. On Windows 8.1 Pro x64 (all updates) Regards, David -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
