NAME

       rhino - invokes the JavaScript shell for running scripts in batch mode or interactive

SYNOPSIS

       rhino [options] script_filename_or_url [script_arguments]

DESCRIPTION

       This  manual  page  documents briefly the rhino command.  This manual page was written for
       the Debian distribution because the original program does not have a manual  page.  It  is
       written according to the html documentation.

       rhino  is a start script for the rhino JavaScript shell which provides a simple way to run
       scripts in batch mode or an interactive environment for exploratory programming.

OPTIONS

       -w     Enable warnings.

       -version versionNumber
              Specifies the language version to compile with. The string  versionNumber  must  be
              one  of 100, 110, 120, 130, 140, 150, 160, 170, 180 or 200. See JavaScript Language
              Versions for more information on language versions.

       -opt, -O optLevel
              Optimizes at level optLevel, which must be an integer between -1 and  9.  -1  means
              Interpretive  mode  is  always  used.  0 means no optimizations whereas 9 means all
              optimizations are performed.

       -f script_filename_or_url
              Reads script_filename_or_url content and execute it as a JavaScript script.

       -e script_source
              Executes script_source as a JavaScript script.

       -modules uri
              Add a single path or URL element to  the  CommonJS  module  search  path.  (implies
              -require)

       -require
              Enable CommonJS module support.

       -sandbox
              Enable CommonJS sandbox mode. (implies -require)

       -debug Generate debug code.

       -strict
              Enable strict mode.

       -fatal-warnings
              Treat warnings as errors.

       -encoding charset
              Use specified character encoding as default when reading scripts.

PREDEFINED PROPERTIES

       Scripts  executing in the shell have access to some additional properties of the top-level
       object.

       arguments
              The arguments object is an array containing the strings of all the arguments  given
              at the command line when the shell was invoked.

       help() Executing the help function will print usage and help messages.

       defineClass(className)
              Define  an extension using the Java class named with the string argument className.
              Uses ScriptableObject.defineClass() to define the extension.

       deserialize(filename)
              Restore from the  specified  file  an  object  previously  written  by  a  call  to
              serialize.

       load([filename,...])
              Load  JavaScript  source files named by string arguments. If multiple arguments are
              given, each file is read in and executed in turn.

       loadClass(className)
              Load and execute the class named by the string argument className. The  class  must
              be  a  class  that  implements the Script interface, as will any script compiled by
              jsc.

       print([expr...])
              Evaluate and print expressions. Evaluates each expression, converts the result to a
              string, and prints it.

       readFile(path[,characterCoding])
              Read  given  file  and  convert its bytes to a string using the specified character
              coding or default character coding if explicit coding argument is not given.

       readUrl(url[,characterCoding])
              Open an input connection to the given string url, read all its  bytes  and  convert
              them  to  a string using the specified character coding or default character coding
              if explicit coding argument is not given.

       runCommand(commandName,[arg,...][options])
              Execute the specified command with the given argument and  options  as  a  separate
              process  and  return  the  exit status of the process. For details, see JavaDoc for
              org.mozilla.javascript.tools.shell.Global#runCommand.

       serialize(object,filename)
              Serialize the given object to the specified file.

       spawn(functionOrScript)
              Run the given function or script in a different thread.

       sync(function)
              creates a synchronized function (in the sense of a Java synchronized  method)  from
              an  existing  function.  The  new  function  synchronizes on the this object of its
              invocation.

       quit() Quit shell. The shell  will  also  quit  in  interactive  mode  if  an  end-of-file
              character is typed at the prompt.

       version([number])
              Get  or  set  JavaScript  version  number.  If no argument is supplied, the current
              version number is returned. If an argument is supplied, it is expected to be one of
              100,  110,  120,  130, or 140 to indicate JavaScript version 1.0, 1.1, 1.2, 1.3, or
              1.4 respectively.
