Trigger a java jar file when a file is modified in the Linux headless machine

Question

I need to trigger a java jar file whenever a file ( report.html ) is updated in linux headless machine.

java -jar readReport.jar

How do I do this?

Thanks in advance.

Answer 1

As I am new to Linux just gave a try with inotifywait, please check if this is correct

#!/bin/sh
while inotifywait -e modify <path-to-report.html> 
do
  java -jar readReport.jar
done

Will this check continuously for the update in a loop and whenever there is an update of (report.html) this jar has to be executed.
