.SH "NAME"
jjs \- Invokes the Nashorn engine\&.

.fi
.if n \{\
.RE

.PP
\fIoptions\fR
.RS 4
One or more options of the
\fBjjs\fR
command, separated by spaces\&. For more information, see Options\&.
.RE
.PP
\fIscript\-files\fR
.RS 4
One or more script files which you want to interpret using Nashorn, separated by spaces\&. If no files are specified, an interactive shell is started\&.
.RE
.PP
\fIarguments\fR
.RS 4
All values after the double hyphen marker (\fB\-\-\fR) are passed through to the script or the interactive shell as arguments\&. These values can be accessed by using the
\fBarguments\fR
property (see Example 3)\&.
.RE
.SH "DESCRIPTION"
.PP
The
\fBjjs\fR
command\-line tool is used to invoke the Nashorn engine\&. You can use it to interpret one or several script files, or to run an interactive shell\&.
.SH "OPTIONS"
.PP
The options of the
\fBjjs\fR
command control the conditions under which scripts are interpreted by Nashorn\&.
.PP
\-cp \fIpath\fR
.br
\-classpath \fIpath\fR
.RS 4
Specifies the path to the supporting class files To set multiple paths, the option can be repeated, or you can separate each path with a colon (:)\&.
.RE
.PP
\-D\fIname\fR=\fIvalue\fR
.RS 4
Sets a system property to be passed to the script by assigning a value to a property name\&. The following example shows how to invoke Nashorn in interactive mode and assign
\fBmyValue\fR
to the property named
\fBmyKey\fR:
.sp
.if n \{\
.RS 4
.\}
.nf
\fB>> \fR\fB\fBjjs \-DmyKey=myValue\fR\fR
\fBjjs> \fR\fB\fBjava\&.lang\&.System\&.getProperty("myKey")\fR\fR
\fBmyValue\fR
\fBjjs>\fR
 
.fi
.if n \{\
.RE
.\}
This option can be repeated to set multiple properties\&.
.RE
.PP
\-doe
.br
\-\-dump\-on\-error
.RS 4
Provides a full stack trace when an error occurs\&. By default, only a brief error message is printed\&.
.RE
.PP
\-fv
.br
\-\-fullversion
.RS 4
Prints the full Nashorn version string\&.
.RE
.PP
\-fx
.RS 4
Launches the script as a JavaFX application\&.
.RE
.PP
\-h
.br
\-help
.RS 4
Prints the list of options and their descriptions\&.
.RE
.PP
\-\-language=[es5]
.RS 4
Specifies the ECMAScript language version\&. The default version is ES5\&.
.RE
.PP
\-ot
.br
\-\-optimistic\-types=[true|false]
.RS 4
Enables or disables optimistic type assumptions with deoptimizing recompilation\&. Running with optimistic types will yield higher final speed, but may increase warmup time\&.
.RE
.PP
\-scripting
.RS 4
Enables shell scripting features\&.
.RE
.PP
\-strict
.RS 4
Enables strict mode, which enforces stronger adherence to the standard (ECMAScript Edition 5\&.1), making it easier to detect common coding errors\&.
.RE
.PP
\-t=\fIzone\fR
.br
\-timezone=\fIzone\fR
.RS 4
Sets the specified time zone for script execution\&. It overrides the time zone set in the OS and used by the
\fBDate\fR
object\&.
.RE
.PP
\-v
.br
\-version
.RS 4
Prints the Nashorn version string\&.
