## 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**.

       -D_name_=_value_
              Sets a Java system property.

### -J_flag_
              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   -f  -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/>
