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

       -e script_source
              Executes script_source as a JavaScript script.

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

       -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.

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

       -strict
              Enable strict mode.

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.
