How to shutdown jshell at the end of the script?

How to instruct jshell to terminate at the end of the script similarly to interpreters of other languages like for example python3 or node?

Following command

./jshell -q /tmp/shell.java

with script /tmp/shell.java

System.out.println("Hello world");

prints

Hello world
jshell>

and waits for further commands. I'd like it to stop immediately at the end of the file.

I'm looking for something more elegant than System.exit(0); at the end of the script.

Another option:

cat /tmp/shell.java | jshell -

Should work the same in bash and windows powershell

Another possibility is to have an exit file:

exit.jsh

/exit

And then run:

./jshell --startup myscript.jsh --startup exit.jsh

Inside the script, use the jshell command /exit. This will exit jshell at the end of your script.
