If you mean that '-[wm]+' (rexexpr syntax) means '-m', that's what I thought made the most sense. IOW '-w' defaults to '\' but does not override '-m', and '-m' implies '-w' unless otherwise specified. Actually I see no problem with '-um', it's just a no-op because '-u' means '-m' anyway. Even '-lu' and '-su' are actually valid... So... '-w' and '-u' are mutually exclusive. '-s', '-l', '-m' imply '-w' unless '-u' used '-d' is an alias for '-ws' Examples: cygpath -su 'c:\program files' --> /cygdrive/c/PROGRA~1 # valid path! cygpath -dm 'c:\program files' --> C:/PROGRA~1 -- Matthew When in doubt, duct tape! -- 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/
