The function of Ctrl-C is conditional, based on whether you use the Windows terminal (cmd.exe) or a Cygwin terminal (mintty/rxvt). Under the Windows terminal, Ctrl-C is ignored, but it works as expected under a Cygwin terminal. >> Alternatively after >> $ ls -l > /tmp/pipe & >> $ cat /tmp/pipe >> >> nothing happens, so I interrupt cat with Ctrl-C, and finally try: >> >> $ cat < /tmp/pipe >> cat: -: Communication error on send I see this behavior under both kinds of terminals. Under Linux, all of the above works as you expect, so this appears to be a Cygwin defect. -Jeremy -- 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
