He is using windows BAT, which isn't super advanced but it looks like the

Is this kind of talk against the code of conduct? I don't think you need to
blast somebody's needs as 'stupid', we don't know the use case here. (Sorry
if cc'ing you JB is against etiquette, I just wanted to flag this message)

and sometimes people do this for a variety of reasons. We don't know the
use case here.
