NAME
       jrunscript - Runs a command-line script shell that supports interactive and batch modes. This
       command is experimental and unsupported.

SYNOPSIS
       jrunscript [options] [arguments]


       options
              The command-line options. See Options.

       arguments
              Arguments,  when  used,  follow  immediately  after  options  or the command name. See
              Arguments.

DESCRIPTION
       The jrunscript command is a language-independent command-line script  shell.  The  jrunscript
       command  supports  both an interactive (read-eval-print) mode and a batch (-f option) mode of
       script execution. By default, JavaScript is the language used, but the -l option can be  used
       to  specify  a  different  language.  By  using Java to scripting language communication, the
       jrunscript command supports an exploratory programming style.

OPTIONS
       -classpath path
              Indicate where any class files are that the script needs to access.

       -cp path
              Same as -classpathpath.

       -Dname=value
              Sets a Java system property.

       -Jflag
              Passes flag directly to the Java Virtual  Machine  where  the  jrunscript  command  is
              running.

       -I language
              Uses  the  specified  scripting language. By default, JavaScript is used. To use other
              scripting languages, you must specify the corresponding script engine's JAR file  with
              the -cp or -classpath option.

       -e script
              Evaluates  the  specified script. This option can be used to run one-line scripts that
              are specified completely on the command line.

       -encoding encoding
              Specifies the character encoding used to read script files.

       -f script-file
              Evaluates the specified script file (batch mode).

       -f -
              Reads and evaluates a script from standard input (interactive mode).

       -help
              Displays a help message and exits.

       -?
              Displays a help message and exits.

       -q
              Lists all script engines available and exits.

ARGUMENTS
       If arguments are present and if no -e or -f option is used, then the first  argument  is  the
       script file and the rest of the arguments, if any, are passed to the script. If arguments and
       -e  or  the -f option are used, then all arguments are passed to the script. If arguments, -e
       and -f are missing, then interactive mode is used. Script arguments are available to a script
       in an engine variable named arguments of type String array.

EXAMPLES
   EXECUTE INLINE SCRIPTS
       jrunscript -e "print('hello world')"
       jrunscript -e "cat('http://www.example.com')"


   USE SPECIFIED LANGUAGE AND EVALUATE THE SCRIPT FILE
       jrunscript -l js -f test.js


   INTERACTIVE MODE
       jrunscript
       js> print('Hello World\n');
       Hello World
       js> 34 + 55
       89.0
       js> t = new java.lang.Thread(function() { print('Hello World\n'); })
       Thread[Thread-0,5,main]
       js> t.start()
       js> Hello World
       js>


   RUN SCRIPT FILE WITH SCRIPT ARGUMENTS
       The test.js file is the script file. The arg1, arg2 and arg3  arguments  are  passed  to  the
       script. The script can access these arguments with an arguments array.

       jrunscript test.js arg1 arg2 arg3


SEE ALSO
       If JavaScript is used, then before it evaluates a user defined script, the jrunscript command
       initializes certain built-in functions and objects. These JavaScript built-ins are documented
       in JsDoc-Toolkit at http://code.google.com/p/jsdoc-toolkit/
