\f3jrunscript\fP is a command line script shell. jrunscript supports both an interactive (read\-eval\-print) mode and a batch (\-f option) mode of script execution. This is a scripting language independent shell. By default, JavaScript is the language used, but the \-l option can be used to specify a different language. Through Java to scripting language communication, jrunscript supports "exploratory programming" style.
\f3NOTE:\fP This tool is \f3experimental\fP and may \f3not\fP be available in future versions of the JDK.
Use the specified scripting language. By default, JavaScript is used. Note that to use other scripting languages, you also need to specify the corresponding script engine's jar file using \-cp or \-classpath option.
Evaluate the given script. This option can be used to run "one liner" scripts specified completely on the command line.
If [arguments...] are present and if no \f3\-e\fP or \f3\-f\fP option is used, then the first argument is the script file and the rest of the arguments, if any, are passed as script arguments. If [arguments..] and \f3\-e\fP or \f3\-f\fP option are used, then all [arguments..] are passed as script arguments. If [arguments..], \f3\-e\fP and \f3\-f\fP are missing, interactive mode is used. Script arguments are available to a script in an engine variable named "arguments" of type String array.

jrunscript test.js arg1 arg2 arg3
test.js is script file to execute and arg1, arg2 and arg3 are passed to script as script arguments. Script can access these using "arguments" array.
