If "ls /cygdrive/c/Windows/System32" is executed, the result is: ls: cannot access '/cygdrive/c/Windows/System32': No such file or directory Also, if try to execute "cmd.exe" in System32 directory, the result is: bash: cmd.exe: command not found. Of cource, /cygdrive/c/WINDOWS/system32 exists in the PATH. So I mean "not opening anything at all". -- Takashi Yano
