NAME
       lua - Lua interpreter

SYNOPSIS
       lua [ options ] [ script	[ args ] ]

DESCRIPTION
       lua  is the standalone Lua interpreter.	It loads and executes Lua pro-
       grams, either in	textual	source form or	in  precompiled	 binary	 form.
       (Precompiled  binaries  are output by luac, the Lua compiler.)  lua can
       be used as a batch interpreter and also interactively.

       The given options are handled in	order and then the Lua program in file
       script  is loaded and executed.	The given args are available to	script
       as strings in a global table named arg.	If no options or arguments are
       given,  then  -v	 -i  is	assumed	when the standard input	is a terminal;
       otherwise, - is assumed.

       In interactive mode, lua	prompts	the user, reads	lines from  the	 stan-
       dard  input,  and  executes  them as they are read.  If a line does not
       contain a complete statement, then a secondary prompt is	displayed  and
       lines  are  read	until a	complete statement is formed or	a syntax error
       is found.  If a line starts with	'=', then lua evaluates	 and  displays
       the values of the expressions in	the remainder of the line.

       At  the	very  start, before even handling the command line, lua	checks
       the contents of the environment variables LUA_INIT_5_2 or LUA_INIT,  in
       that  order.  If	the contents is	of the form '@filename', then filename
       is executed.  Otherwise,	the string is assumed to be  a	Lua  statement
       and is executed.

OPTIONS
       -e stat
	      execute statement	stat.

       -i     enter interactive	mode after executing script.

       -l name
	      execute  the equivalent of name=require('name') before executing
	      script.

       -v     show version information.

       -E     ignore environment variables.

       --     stop handling options.

       -      stop handling options and	execute	the standard input as a	file.

DIAGNOSTICS
