Listing All Environment Variables ...With Java 8 And JavaScript

With Java 8 you can use JavaScript / Nashorn instead of bash / zsh syntax for shell scripting:

#!/usr/bin/jjs -fv
for (entry in $ENV) {
    print(entry + "->" + $ENV[entry]);

JavaScript shell scripting is particularly interesting for automation and system testing.

See you at Java EE Workshops at MUC Airport or on demand and in a location very near you:!


Interesting, this fails on Windows with a ReferenceError: "$ENV" is not defined

launch jjs with "jjs -scripting"
instead of simply "jjs"

and $ENV will be accessible on wincows
