jrunscript - What Is It

This section describes what is 'jrunscript' - a command line tool that allows you to run script code that in interactive or batch mode.

What Is "jrunscript"? "jrunscript" is a command line tool that allows you to run script code that in interactive or batch mode.

By default, "jrunscript" only supports JavaScript language. But it can support other scripting languages, if you have the script engine specified in the class path.

If you have %java_home%\bin directory included in "path" the environment variable, you can run "jrunscript -help" to get the usage information:

herong> jrunscript -help

Usage: jrunscript [options] [arguments...]

where [options] include:
  -classpath <path>    Specify where to find user class files 
  -cp <path>           Specify where to find user class files 
  -D<name>=<value>     Set a system property 
  -J<flag>             Pass <flag> directly to the runtime system 
  -l <language>        Use specified scripting language 
  -e <script>          Evaluate given script 
  -encoding <encoding> Specify character encoding used by script files 
  -f <script file>     Evaluate given script file 
  -f -                 Interactive mode, read script from standard input 
                       If this is used, this should be the last -f option 
  -? -h --help -help   Print this help message and exit 
  -q                   List all scripting engines available and exit 
  
If [arguments..] are present and if no -e or -f option is used, then first
argument is script file and the rest of the arguments, if any, are passed
as script arguments. If [arguments..] and -e or -f option is used, then all
[arguments..] are passed as script arguments. If [arguments..], -e, -f are
missing, then interactive mode is used.
