Well, there's that, and there's also the fact that Cygwin has to emulate exec. It's not a Windows function. There is no way to tell, e.g., a Windows command shell to keep waiting for a new process that has been execed without keeping the old one around. See CreateProcess and the WaitFor* functions. 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/
