NAME
       luajit -	Just-In-Time Compiler for the Lua Language

SYNOPSIS
       luajit [options]... [script [args]...]

WEB SITE
       https://luajit.org

DESCRIPTION
       This is the command-line	program	to run Lua programs with LuaJIT.

       LuaJIT is a just-in-time	(JIT) compiler for the Lua language.  The vir-
       tual  machine (VM) is based on a	fast interpreter combined with a trace
       compiler. It can	significantly improve the performance of Lua programs.

       LuaJIT is API- and ABI-compatible with the VM of	the  standard  Lua 5.1
       interpreter.  When  embedding the VM into an application, the built li-
       brary can be used as a drop-in replacement.

OPTIONS
       -e chunk
	      Run the given chunk of Lua code.

       -l library
	      Load the named library, just like	require("library").

       -b ... Save or list bytecode. Run without arguments to get help on  op-
	      tions.

       -j command
	      Perform LuaJIT control command (optional space after -j).

       -O[opt]
	      Control LuaJIT optimizations.

       -i     Run in interactive mode.

       -v     Show LuaJIT version.

       -E     Ignore environment variables.

       --     Stop processing options.

       -      Read script from stdin instead.

       After  all  options  are	processed, the given script is run.  The argu-
       ments are passed	in the global arg table.

       Interactive mode	is only	entered, if no script  and  no	-e  option  is
       given. Interactive mode can be left with	EOF (Ctrl-Z).

EXAMPLES
       luajit hello.lua	world

	      Prints "Hello world", assuming hello.lua contains:
		print("Hello", arg[1])

       luajit -e "local	x=0; for i=1,1e9 do x=x+i end; print(x)"

	      Calculates the sum of the	numbers	from 1 to 1000000000.
	      And finishes in a	reasonable amount of time, too.

       luajit -jv -e "for i=1,10 do for	j=1,10 do for k=1,100 do end end end"

	      Runs some	nested loops and shows the resulting traces.
