Should I Learn Batch Script or PowerShell Script First?

Honestly, I'd say skip both and go for Bash instead. There's definitely more demand for Bash scripting, and with Windows Subsystem for Linux (WSL), you don't even need a separate Linux setup to practice. If you're managing Windows systems, PowerShell is great, but Bash is much more widely used in general.

Batch and PowerShell are quite different. Batch is simpler and you can learn it pretty quickly, maybe even in a couple of hours. PowerShell, on the other hand, is really powerful and versatile, especially for Windows system administration. If you're serious about scripting, I'd recommend jumping straight into PowerShell. Plus, aside from learning for fun, Batch doesn't have much practical use anymore.

Batch is fine for very basic tasks, but PowerShell has become the go-to for automating and managing Windows. If you're keen on learning something that'll really help you in the long run, PowerShell is the way to go.

Just a heads up, are you mixing up Batch with Bash? They are two different things. Batch is the older MS-DOS scripting language, while Bash is commonly used in Unix/Linux environments.

If you want something practical, Python is a good choice since it has a wide range of applications. But if it has to be one of those two, definitely go for PowerShell.
