jps [options] [hostid]

jps lists instrumented Java Virtual Machine processes on the local system or a remote host. It functions as a Java-specific equivalent of ps, showing the process ID and main class name for each running JVM.
The -l flag displays fully qualified class names or JAR paths, making it easier to distinguish between multiple Java applications. Use -v to see the JVM arguments each process was started with, and -m to see the arguments passed to the main method. These options can be combined (e.g., -lvm) for comprehensive process information.
The tool works by reading the JVM's performance data directory, so it can only see processes running under the same user (or all processes when run as root).
