It's interesting because #1 is still suggesting a shell script, it's just suggesting a better shell to script.
I think pwsh is worth exploring. It is cross-platform. It is post-Python and the Python mantra that "~~code~~ scripts are read more often than they are written". It provides a lot of nice tools out of the box. It's built in an "object-oriented" way, resembling Python and owing much to C#. When done well the "object-oriented" way provides a number of benefits over "dumb text pipes" that shells like bash were built on. It is easy to extend with C# and a few other languages, should you need to extend it.
I would consider not dismissing it off hand without trying it just because Microsoft built it and/or that it was for a while Windows-only.
Also, the newer versions aren't included with Windows, which would have been useful – instead Windows includes an incompatible older version that admonishes you to download the new version. But why would you download several hundred megabytes of pwsh when you can equally well download any other language runtime?
Also, it sends "telemetry" to Microsoft by default.
Also, the error handling is just awful, silencing errors by default, requiring several different incantations to fix.
Also, the documentation is vague and useless. And the syntax is ugly.
The new versions aren't included in Windows and the old versions are still in Windows for the exact same reasons of Windows backwards compatibility requirements. But at this point the bootstrap on Windows is as easy as `winget install --id Microsoft.PowerShell`.
The error handling isn't far from the bash defaults, but the magic incantations actually tell you what they do versus the number of bash scripts littered with `set -euxo pipefail` is the exact same as the number of scripts that need an `$ErrorActionPreference = "Stop"` and/or a `$PSNativeCommandUseErrorActionPreference = true`.
I find the documentation less vague and more useful than the average `man` page and the syntax is fine (and better than bash) to me, but I understand how much of that is personal preference and familiarity.
