NAME

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

SYNOPSIS

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

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.
