When you say "pass arguments", the methodology you outline definitely
isn't going to fly with argument passing. When a command is invoked the
arguments are taken from the command line, so it isn't possible to pass
further arguments at a later time.

You probably need to write to you sub-process's standard input stream.
which you can do whit the subprocess module (the modern way to do it) or
one of the various popen() functions.
