> Powershell has mv and cp but they don't work the same way or have the same flags. The better idea would not be to try running bash scripts in it, that won't work. The idea would be to use Powershell for your scripts on all three platforms, where Move-Item and Copy-Item do work the same. In Powershell 'mv' and 'cp' are aliases to Powershell commands, which is why they behave differently. As a Unix Powershell user, I don't want or like that, so I remove them. Scripts can always spell things the canonical way and so be guaranteed of the correct behavior. There's a huge caveat to this, but it's no less true for Python or any other language, and that is that lots of platform differences are semantic and not addressable by any shell. In my experience you run into these "other factors" pretty quick, but in the domain of build scripts, they might not matter much.
