Elixir script the shell
– Andi, 2018-10-17

I’m using Elixir as a scripting language for the shell

And it’s that easy …

Write a file, hello.exs for example.

#!/usr/bin/env elixir
defmodule Greeter do
  def hello(name), do: IO.puts "Hello, #{name}!"

# Main
Greeter.hello( hd(System.argv() )

Don’t forget to chmod +x hello.exs and then use the script from the terminal with

$ ./hello World
Hello, World!

For more complex scenarios you can use Elixir‘s OptionParser and all the sugar that comes with that beautiful language.
