I read in a very old post where you said that Cygwin with bash was not needed, Python on cmd works fine.
I happen to have Cygwin and its Python package(s) installed.  Do you recommend not using this, and to install "Windows Python" to use with cmd?

I'd say "use whatever works". A "Windows Python" install will definitely work. A "Cygwin Python" installation may work, so if that's what you have installed - and it's working - then sure, keep using it!

But I wouldn't recommend installing Cygwin just to use this script, as that's not required and may potentially result in unforeseen problems.

Also, do you know whether your utility has been used successfully on Android?
I have been using Termux for a while, and it has Python packages available. I thought this might be a way to use your utility on Android.

So long as the Android device has a fairly standard version of Python2 (or Python3) available then it should be possible to run the script on the device. If not, then running the script from another device (Linux/Windows PC, Raspberry Pi etc.) and specifying the IP address of the Android client is probably your only option.
