lua(1)                                                                  lua(1)


       lua - Lua interpreter


       lua [ options ] [ script [ args ] ]


       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 the line contains
       an expression or list of expressions, then the line  is  evaluated  and
       the  results are printed.  If a line does not contain a complete state-
       ment, then a secondary prompt is displayed and lines are read  until  a
       complete statement is formed or a syntax error is found.

       At  the  very  start, before even handling the command line, lua checks
       the contents of the environment variables LUA_INIT_5_3 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.


       -e stat
              execute statement stat.

       -i     enter interactive mode after executing script.

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

       -v     show version information.

       -E     ignore environment variables.

       --     stop handling options.

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


       The  documentation  at,  especially section 7 of the reference


       Error messages should be self explanatory.
