Today I came across something I don’t think many people know.
Java 6 has a fully functional ECMAscript command line tool, with a interactive console
the cool thing is that you can use all your java libraries from it.
It also has some commands to do file system manipulation like cd and cp etc.

C:\>jrunscript -q
Language ECMAScript 1.6 implemention "Mozilla Rhino" 1.6 release 2
 
C:\>jrunscript -e "var a =1;eval("a=a+1");println(a);

C:\>jrunscript
js> println(new java.util.Date);
