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.

Answer

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