.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\&.
