DESCRIPTION
This manual page documents briefly the rhino command.
rhino is a start script for the rhino JavaScript shell which provides a
simple way to run scripts in batch mode or an interactive environment
for exploratory programming.
OPTIONS

to zero.
-e script_source
Executes script_source as a JavaScript script.
-encoding characterEncoding

tected.
-f script_filename_or_url
Reads script_filename_or_url content and execute it as a Java-
Script script.
-fatal-warnings
Set warnings as errors.
-help, -?
Display help.
-modules module
Add a module to the path.
-opt, -O optLevel
Optimizes at level optLevel, which must be an integer between 0
and 9.
-require
Use require().
-sandbox
The created require() instances will be sandboxed.
-sealedlib
Use a sealed standard library.
-strict
Set strict mode.
-version versionNumber
Specifies the language version to compile with. It must be one
of 100, 110, 120, 130, 140, 150, 160, 170, 180 or 200.

PREDEFINED PROPERTIES
Scripts executing in the shell have access to some additional proper-
ties of the top-level object.
arguments
The arguments object is an array containing the strings of all
the arguments given at the command line when the shell was in-
voked.
help() Executing the help function will print usage and help messages.
defineClass(className)
Define an extension using the Java class named with the string
argument className. Uses ScriptableObject.defineClass() to de-
fine the extension.
deserialize(filename)
Restore from the specified file an object previously written by
a call to serialize.
load([filename,...])
Load JavaScript source files named by string arguments. If mul-
tiple arguments are given, each file is read in and executed in
turn.
loadClass(className)
Load and execute the class named by the string argument class-
Name. The class must be a class that implements the Script in-
terface, as will any script compiled by jsc.
print([expr...])
Evaluate and print expressions. Evaluates each expression, con-
verts the result to a string, and prints it.
readFile(path[,characterCoding])
Read given file and convert its bytes to a string using the
specified character coding or default character coding if ex-
plicit coding argument is not given.
readUrl(url[,characterCoding])
Open an input connection to the given string url, read all its
bytes and convert them to a string using the specified character
coding or default character coding if explicit coding argument
is not given.
runCommand(commandName,[arg,...][options])
Execute the specified command with the given argument and op-
tions as a separate process and return the exit status of the
process. For details, see JavaDoc for org.mozilla.java-
script.tools.shell.Global#runCommand.
setTimeout(function[,delay,arg,...])
Execute "function" after "delay" milliseconds. (If "delay" is
not set, then it is set to 0.) Pass any trailing parameters as
arguments. Timeouts run after the current function is done exe-
cuting, and in the interactive shell, only after the shell is
exited. Return an ID that may be passed to "clearTimeout".
clearTimeout(id)
Cancel a timeout set using "setTimeout".
serialize(object,filename)
Serialize the given object to the specified file.
spawn(functionOrScript)
Run the given function or script in a different thread.
sync(function)
creates a synchronized function (in the sense of a Java synchro-
nized method) from an existing function. The new function syn-
chronizes on the this object of its invocation.
quit() Quit shell. The shell will also quit in interactive mode if an
end-of-file character is typed at the prompt.
version([number])
Get or set JavaScript version number. If no argument is sup-
plied, the current version number is returned. If an argument is
supplied, it is expected to be one of 100, 110, 120, 130, 150,
160, 170, 180 or 200 to indicate JavaScript version 1.0, 1.1,
1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8 or ECMAScript 6 respectively.
write([expr...])
Evaluate and print expressions like in "print", but without the
trailing newline.
