What to do instead: Use Nushell.

I finally started really using my shell after switching to it. I casually write multiple scripts and small functions per day to automate my stuff. I'm writing scripts I'd otherwise write in python in nu. All because the data needs no parsing. I'm not even annotating my data with types even though Nushell supports it because it turns out structured data with inferred types is more than you need day-to-day. I'm not even talking about all the other nice features other shells simply don't have. See this custom command definiton:

  # A greeting command that can greet the caller
  def greet [
    name: string      # The name of the person to greet
    --age (-a): int   # The age of the person
  ] {
    [$name $age]
  }

Here's the auto-generated output when you run `help greet`:

  A greeting command that can greet the caller

  Usage:
    > greet <name> {flags}

  Parameters:
    <name> The name of the person to greet

  Flags:
    -h, --help: Display this help message
    -a, --age <integer>: The age of the person

It's one of the software that only empowers you, immediately, without a single downside. Except the time spent learning it, but that was about a week for me. Bash or fish is there if I ever need it to paste some shell commands.
