in thread Proc::Background does not take file path with spaces

On a windows command line, your parameters are all (white?)space separated. If you want a zero-length parameter you need to double quote it so it isn't ignored, like so:

USAGE: mangle.exe [filename] [password] [index number] mangle.exe unprotected.dat "" 42

Parameters that are all whitespace have the same problem and solution.

No idea on why it had to be done that way though.

    If you want a zero-length parameter

    Hm. Okay, you got me there. Mind you, in 30 years I don't remember ever having used a command that took a "zero length parameter".

    Every command I'm aware of that takes a password has an option to supply it. And optional parameters always come at the end.

      Hi Guys I end up using the following
      use Win32; $CommandNew = Win32::GetShortPathName("C:\\Program Files (x86)\\vs.exe +"); Proc::Background->new($CommandNew);
      Thanks for looking
