"jrunscript" - Scripting Shell Command and Options
After installing JDK on my machine, I want to get some help information on how to use the "jrunscript" command by running it with the "-help" option:
C:\herong>\progra~1\java\jdk-10.0.1\bin\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 -help Print this usage message and exit -? Print this usage 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.
As the first test, I want to see what are the scripting engines supported by JDK by using the "-q" option:
C:\herong>\progra~1\java\jdk-10.0.1\bin\jrunscript -q Language ECMAScript ECMA - 262 Edition 5.1 implementation "Oracle Nashorn" 10.0.1
