You CAN create a file called nul, though. But even then, the test fails. $ VER & IF EXIST "%SystemRoot%\nul" ( ECHO y ) ELSE ( ECHO n ) Microsoft Windows [Version 6.1.7601] n $ ECHO. > "\\.\%SystemRoot%\nul" $ DIR /B "%SystemRoot%\n*" nul notepad.exe $ IF EXIST "%SystemRoot%\nul" ( ECHO y ) ELSE ( ECHO n ) n However, you can test for "%~f1\*". But since the behavior is not documented, you can't rely on such test either. -- WBR, Andrey Repin (anrdae...@yandex.ru) 09.09.2014, <18:22> Sorry for my terrible english... -- 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
