Calling subprocess with arguments

Hello,

The problem might be that, aside from creating the Popen object, to
get the command run you need to call 'communicate' (other options, not
used with the Popen object directly, are 'call' or 'waitpid' as
explained in the documentation). Did you do that?

Best regards,
    Javier
