It doesn't work as-is because $SYSTEMROOT = C:\Windows (and this is therefore not interpreted by the path). Rephrasing, what do I use to translate "C:\WINDOWS" to "/cygdrive/c/windows"? I had to do this because some nasty things in my path were causing problems (e.g. ClearQuest/ClearCase) TIA, Jason. -- 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/
