To compile from shell, first create a file:

# module_name.ex
defmodule ModuleName do
  def hello do
    IO.puts "Hello World"
  end
end

Then run shell and compile:

Interactive Elixir
iex> c("module_name.ex")
[ModuleName]
iex> ModuleName.hello
Hello world!
:ok

You can compile an elixir file using the elixirc command.

So if you have a file named file.ex, you can run:

elixirc file.ex

This will create a .beam file in the current directory for each module defined in your file. If you start iex in this directory your modules from the file will be available.

Here you can read more about this command in the official guides.

You can also execute from command line. Save the file with a .exs extension (file.exs).

For example file.exs contains this line of code:

IO.puts "Hello World"

Then execute it with elixir from command line like this:

$ elixir file.exs
Hello World
