The jrunscript Command- Line Shell - Scripting in Java: Integrating with Groovy and JavaScript - page 275

Table 9-1. The List of Options for the jrunscript Shell

Option Description

-classpath <path>

Used to specify the CLASSPATH.

-cp <path>

The same as the -classpath option.

-D<name>=<value>

Sets a system property for Java runtime.

-J<flag>

Passes the specified <flag> to the JVM on which
jrunscript is run.

-l <language>

Allows you to specify a scripting language that you want
to use with the jrunscript . By default, Rhino JavaScript is
used in JDK 6 and JDK 7. In JDK 8, Nashorn is the default.
If you want to use a language other than JavaScript, say
JKScript , you will need to use -cp or -classpath option to
include the JAR file that contains the script engine.

-e <script>

Executes the specified script. Typically, it is used to execute
a one-liner script.

-encoding <encoding>

Specifies the character encoding used while reading
script files.

-f <script-file>

Evaluates the specified script-file in batch mode.

-f -

Allows you to evaluate scripts in interactive mode. It reads
scripts from the standard input and executes it.

-help

Outputs the help message and exits.

-?

Outputs the help message and exits.

-q

Lists all available script engines and exits. Note that script
engines other than JavaScript are available only when you
include their JAR files using the -cp or -classpath option.

The [arguments] part of the command is a list of arguments, which are interpreted
depending on whether the -e or -f option is used or not. Arguments that are passed
to the script are available inside the script as an object named arguments . Please refer
to Chapter 4 for more details on using the arguments object in scripts. Table 9-2 lists
interpretations of the arguments when they are used with the -e or -f option.
