This draft JEP contains a proposal to enhance the |java| launcher to support running a program supplied as a single file of Java source code. The program will be compiled and run, without the need to explicit invoke javac, or to package up a jar file. For more details, see: http://openjdk.java.net/jeps/8192920 -- Jon Most welcome! One comment, though: As a linux/unix user, I'd expect the jshell executable to be the processor for jshell scripts, not the compiler ("java"). This would tie in with the established pattern of other shell script processors/repl, e.g. groovysh, or even plain bash. Best regards, /Lennart

Lennart,

The content of a source file supported by this feature is the source code for a normal Java class containing a normal "public static void main(String[])" method.  It is not the same as the input you might give to jshell, which is a combination of "snippets" of Java code and commands for the JShell tool, which are designed for use in an interactive environment.
