       This manual page documents briefly the rhino command.

       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.

       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.

       setTimeout(function[,delay,arg,...])
              Execute  "function" after "delay" milliseconds. (If "delay" is not set, then it is set to 0.) Pass
              any trailing parameters as arguments. Timeouts run after the current function is  done  executing,
              and  in  the interactive shell, only after the shell is exited. Return an ID that may be passed to
              "clearTimeout".

       clearTimeout(id)
              Cancel a timeout set using "setTimeout".

       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, 150, 160,
              170, 180 or 200 to indicate JavaScript version 1.0, 1.1, 1.2, 1.3, 1.4,  1.5,  1.6,  1.7,  1.8  or
              ECMAScript 6 respectively.

       write([expr...])
              Evaluate and print expressions like in "print", but without the trailing newline.

       console
              The  console  object provides a simple debugging console similar to the console object provided by
              web browsers.

              console.log(format[arg,...])
                     For general output of logging information. String substitution and additional arguments are
                     supported. Prints formatted text according to the format  and  args  supplied  with  "INFO"
                     prefix. This function is identical to console.info(format[arg,...]).

              console.trace(format[arg,...])
                     This  function is identical to console.log(format[arg,...]) except it prints "TRACE" prefix
                     instead of "INFO".

              console.debug(format[arg,...])
                     This function is identical to console.log(format[arg,...]) except it prints "DEBUG"  prefix
                     instead of "INFO".

              console.info(format[arg,...])
                     This function is identical to console.log(format[arg,...]).

              console.warn(format[arg,...])
                     This  function  is identical to console.log(format[arg,...]) except it prints "WARN" prefix
                     instead of "INFO".

              console.error(format[arg,...])
                     This function is identical to console.log(format[arg,...]) except it prints "ERROR"  prefix
                     instead of "INFO".

              console.assert(expression[arg,...])
                     Prints error if expression is false. If args are supplied, they will be printed also.

              console.count([label])
                     Increases the counter of label by one which starts from zero and prints the label and value
                     after increment. If label is not supplied, "default" is the label.

              console.countReset([label])
                     Resets the counter of label to zero. If label is not supplied, "default" is the label.

              console.time([label])
                     Starts  a  timer  of  label.  Use  console.timeEnd([label]) to stop the timer and print the
                     elapsed time. Use console.timeLog([label]) to print the elapsed time without  stopping  the
                     timer.

              console.timeLog([label])
                     See console.time([label]).

              console.timeEnd([label])
                     See console.time([label]).
