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

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

WEB SITE
       http://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
       virtual 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
       library 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
              options.

       -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
       arguments 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.
