I'd love to see an example. Let's say I'm on a Debian server. How would I acquire Powershell (is it GPL/MIT?) and use it to convert some JSON?

Powershell Core and .NET core are MIT Licensed as of 2016 https://github.com/PowerShell/PowerShell/blob/master/LICENSE...

Debian install instructions https://docs.microsoft.com/en-us/powershell/scripting/instal...

Enable https, add feed, apt install

As someone who started out scripting in Powershell but preferred Linux as an OS. I found myself missing powershell's object passing in opposition to bash's string passing.

That being said I now primarily use iPython for advanced shell tasks as I can leverage all of Python's libraries like JSON or YAML.

TBH they're both excellent choices. nushell looks really good too. The point is not to scrape text - rather than write a bash script that can handle JSON properly, write a pwsh/python/nushell script that handle everything properly (ie, by selecting fields rather than scraping text).

Terrific, thank you!

You'd install it via apt obviously. For Ubuntu:

    curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -
    sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/microsoft-debian-jessie-prod jessie main" > /etc/apt/sources.list.d/microsoft.list'
    sudo apt-get update
    sudo apt-get install -y powershell

I'm a node developer, here's what I used to find packages that had a cracked dependency recently:

    $results = @{} 
    ls -recurse -filter "eslint-scope" | foreach { 
      $file = "${PSItem}\package.json" 
      $version = cat $file | convertfrom-json | select -ExpandProperty version 
      $results.Add($file,$version) } 
    echo $results | format-list

PS. pwsh should really combine reading a file, determining it's type, and parsing it, into one command. Like:

    open $file | select -ExpandProperty version 

I know I can make this, it just should be in the stdlib.

As someone fairly ignorant of Powershell, how well does it interact with the rest of the Unix-minded ecosystem? jq is nice because its plainly compatible with being piped into another command like xargs. I don't want a better jq if it means relearning and remastering everything else along with it.

The same as any other CLI app.

As I said, better jq may be equal to:

pwsh -Command "(cat test.json | ConvertFrom-Json).Whatever.Property.Or.Normal.Filter"
