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.


    With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
    "Science is about questioning the status quo. Questioning authority".
    In the absence of evidence, opinion is indistinguishable from prejudice.

    The start of some sanity?

      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
