    it fails is rather unspecific, but I'm guessing you mean that the error message is still displayed on the screen.

    So, what is the difference betweeen "command prompt" and using back-ticks? The most obvious is the shell you are using for "command prompt". I can't find in your posts which operating system you are using. The path style is UNIX-like, yet the use of NUL: is Windows (on UNIX/Linux you would use /dev/null).

    I just tried a simple version of your command on Windows and Linux and it worked as I would expect - no output was displayed on either. It was not using p4 though.
