Should be under powershell.py ?

Batch and bat is for windows

Batch scripts have always been running under shell through jupyter even without the aliases. This is just to catch a few cases where models specifically mention batch or bat. I think powershell is differentiated because its running in a separate process. Jupyter might be able to run powershell as well I'm not sure, but also powershell can't run batch scripts directly.
