SYNOPSIS

elixir [options] [script] [args]

elixir runs Elixir code and scripts. It's the primary command for executing Elixir programs, supporting both script files (.exs) and compiled modules.
The command starts the Erlang VM with Elixir loaded. Options control distributed computing settings, code loading, and execution mode. Combined with `-S mix`, it runs Mix tasks.
Elixir's interactive shell (IEx) can be started using `elixir -S iex` for development and debugging.
