cat <<USAGE >&2
Usage: $(basename "$0") [options] [.exs file] [data]
## General options
-e "COMMAND" Evaluates the given command (*)
-h, --help Prints this message (standalone)
-r "FILE" Requires the given files/patterns (*)
-S SCRIPT Finds and executes the given script in \$PATH
-pr "FILE" Requires the given files/patterns in parallel (*)
-pa "PATH" Prepends the given path to Erlang code path (*)
-pz "PATH" Appends the given path to Erlang code path (*)
-v, --version Prints Erlang/OTP and Elixir versions (standalone)
--erl "SWITCHES" Switches to be passed down to Erlang (*)
--eval "COMMAND" Evaluates the given command, same as -e (*)
--logger-otp-reports BOOL Enables or disables OTP reporting
--logger-sasl-reports BOOL Enables or disables SASL reporting
--no-halt Does not halt the Erlang VM after execution
--short-version Prints Elixir version (standalone)
--werl Uses Erlang's Windows shell GUI (Windows only)
Options given after the .exs file or -- are passed down to the executed code.
Options can be passed to the Erlang runtime using \$ELIXIR_ERL_OPTIONS or --erl.
## Distribution options
The following options are related to node distribution.
--cookie COOKIE Sets a cookie for this distributed node
--hidden Makes a hidden node
--name NAME Makes and assigns a name to the distributed node
--rpc-eval NODE "COMMAND" Evaluates the given command on the given remote node (*)
--sname NAME Makes and assigns a short name to the distributed node
--name and --sname may be set to undefined so one is automatically generated.
## Release options
The following options are generally used under releases.
--boot "FILE" Uses the given FILE.boot to start the system
--boot-var VAR "VALUE" Makes \$VAR available as VALUE to FILE.boot (*)
--erl-config "FILE" Loads configuration in FILE.config written in Erlang (*)
--pipe-to "PIPEDIR" "LOGDIR" Starts the Erlang VM as a named PIPEDIR and LOGDIR
--vm-args "FILE" Passes the contents in file as arguments to the VM
--pipe-to starts Elixir detached from console (Unix-like only).
It will attempt to create PIPEDIR and LOGDIR if they don't exist.
See run_erl to learn more. To reattach, run: to_erl PIPEDIR.
** Options marked with (*) can be given more than once.
** Standalone options can't be combined with other options.
