When using the tool above, and looking at process properties->threads for cygpath, it shows two threads. One's state is Wait:Executive, the other's is Wait:UserInput (both in NTDLL.DLL). Sure enough, changing my test to #!/bin/bash FOO=`cygpath -S < /dev/null` does not hang. I've seen behavior like this before with one of our apps all the way back to pre 1.3.22 days, but I never got a chance to debug it. We already launched it from a script, and it required no user input, so I just did the above. I'll keep digging to see if I can figure out why it is looking for user input. BTW, when viewing cygpath's handles, I see two WinStation ones. Just wondering if that means anything given the recent xemacs issues. I think I have your patch for that in my Cygwin DLL, though. -- Brian Ford Senior Realtime Software Engineer VITAL - Visual Simulation Systems FlightSafety International Phone: 314-551-8460 Fax: 314-551-8444 -- 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/
