          If you feel like learning a third shell, I find that Nushell is even easier to use than PowerShell.

          open stuff.json | each { get fieldName } | where { str starts-with "asdf" } | each { $in | str upcase }

          This gets all the objects in the given json file, then grabs the value of the field named “fieldName”, then filters all those values to find the ones that start with and, converts those to uppercase, and prints them to the screen as a nicely formatted list

            You don’t need the $in | in that last command. each { str upcase } will already pipe each item to the str upcase command.

          Yeah, it does tend to be hard to determine when to use () {} [] etc.
          Even after I RTFM and used those in scripts multiple times, I tend to forget it by the time I need to implement something next.
