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.

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.
