This command is experimental and unsupported\&. .SH SYNOPSIS .sp .nf \fBjrunscript\fR [\fIoptions\fR] [\fIarguments\fR] .fi .sp .TP \fIoptions\fR The command-line options\&. See Options\&. .TP \fIarguments\fR Arguments, when used, follow immediately after options or the command name\&. See Arguments\&. .SH DESCRIPTION The \f3jrunscript\fR command is a language-independent command-line script shell\&. The \f3jrunscript\fR command supports both an interactive (read-eval-print) mode and a batch (\f3-f\fR option) mode of script execution\&. By default, JavaScript is the language used, but the \f3-l\fR option can be used to specify a different language\&. By using Java to scripting language communication, the \f3jrunscript\fR command supports an exploratory programming style\&. .SH OPTIONS .TP -classpath \fIpath\fR .br Indicate where any class files are that the script needs to access\&. .TP -cp \fIpath\fR .br Same as \f3-classpath\fR\f3path\fR\&. .TP -D\fIname\fR=\fIvalue\fR .br Sets a Java system property\&. .TP -J\fIflag\fR .br Passes \f3flag\fR directly to the Java Virtual Machine where the \f3jrunscript\fR command is running\&. .TP -I \fIlanguage\fR .br 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 \f3-cp\fR or \f3-classpath\fR option\&. .TP -e \fIscript\fR .br Evaluates the specified script\&. This option can be used to run one-line scripts that are specified completely on the command line\&. .TP -encoding \fIencoding\fR .br Specifies the character encoding used to read script files\&. .TP -f \fIscript-file\fR .br Evaluates the specified script file (batch mode)\&. .TP -f - .br Reads and evaluates a script from standard input (interactive mode)\&. .TP -help .br Displays a help message and exits\&. .TP -? .br Displays a help message and exits\&. .TP -q .br Lists all script engines available and exits\&. .SH ARGUMENTS If arguments are present and if no \f3-e\fR or \f3-f\fR 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 \f3-e\fR or the \f3-f\fR option are used, then all arguments are passed to the script\&. If arguments, \f3-e\fR and \f3-f\fR are missing, then interactive mode is used\&. Script arguments are available to a script in an engine variable named \f3arguments\fR of type \f3String\fR array\&. .SH EXAMPLES .SS EXECUTE\ INLINE\ SCRIPTS .sp .nf \f3jrunscript \-e "print(\&'hello world\&')"\fP .fi .nf \f3jrunscript \-e "cat(\&'http://www\&.example\&.com\&')"\fP .fi .nf \f3\fP .fi .sp .SS USE\ SPECIFIED\ LANGUAGE\ AND\ EVALUATE\ THE\ SCRIPT\ FILE .sp .nf \f3jrunscript \-l js \-f test\&.js\fP .fi .nf \f3\fP .fi .sp .SS INTERACTIVE\ MODE .sp .nf \f3jrunscript\fP .fi .nf \f3js> print(\&'Hello World\en\&');\fP .fi .nf \f3Hello World\fP .fi .nf \f3js> 34 + 55\fP .fi .nf \f389\&.0\fP .fi .nf \f3js> t = new java\&.lang\&.Thread(function() { print(\&'Hello World\en\&'); })\fP .fi .nf \f3Thread[Thread\-0,5,main]\fP .fi .nf \f3js> t\&.start()\fP .fi .nf \f3js> Hello World\fP .fi .nf \f3\fP .fi .nf \f3js>\fP .fi .nf \f3\fP .fi .sp .SS RUN\ SCRIPT\ FILE\ WITH\ SCRIPT\ ARGUMENTS The test\&.js file is the script file\&. The \f3arg1\fR, \f3arg2\fR and \f3arg3\fR arguments are passed to the script\&. The script can access these arguments with an arguments array\&. .sp .nf \f3jrunscript test\&.js arg1 arg2 arg3\fP .fi .nf \f3\fP .fi .sp .SH SEE\ ALSO If JavaScript is used, then before it evaluates a user defined script, the \f3jrunscript\fR 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/ .RE .br 'pl 8.5i 'bp
