Grasshopper-Python: How to start a CMD-Window and send commands to it with options

Scripting

Hi there.

Within GH via Python code I am trying to open a Command Prompt (Windows 7) and executing some commands in it.
The only thing I manage to do is just to open the CMD window and run a command without options like: “_Run C:/Windows/notepad.exe” or “_Run tasklist”
But any further options to that are ignored. So “_Run tasklist -v” or “_Run echo hello world” doesn’t work.
Can someone point me in the right direction what to do to get this working?
How to run several commands in a row in the same cmd window?

Thanks in advance.
