The elixir command executes Elixir scripts and expressions on the Erlang BEAM virtual machine, enabling concurrent, fault-tolerant applications. Elixir, a dynamic functional language built atop Erlang, excels in scalability with lightweight processes, hot code swapping, and distribution.

elixir compiles and runs .ex (source) or .exs (script) files non-interactively, ideal for automation, deployments, or batch processing. Arguments pass to scripts via System.argv/0. It supports code loading, path manipulation, and app bootstrapping, inheriting Erlang's robustness for telecom-grade reliability.

Key strengths include pattern matching, immutability, and macros for metaprogramming. Used in projects like Phoenix framework for web apps.

Non-interactive; use iex for REPL. Requires Elixir installation. Errors halt execution unless handled.

elixir -e "IO.puts 'Hello World'"
elixir myscript.exs arg1 arg2
elixir -S mix run

.ex: compiled modules.
.exs: scripts, no beam files.

Created by José Valim in 2011 as dynamic alternative to Erlang; first stable release 1.0 in 2014. elixir command evolved with OTP integration, improving concurrency and tooling.
