AFAIK there is no pure Java way. Once I posted a JNI implementation on this forum., but not not find it any longer. If you put up with the PID of a starter script, you can do this:java -Dpid="$$" Caveat: threads under Linux show as processes.

Another suggestion was to exec an program which outputs its parent's PID. Something like this:

#include <unistd.h>

#include <stdio.h>

int main() {

printf("%d\n",getppid());

}

This works only if exec goes directly, that is, if there is no intermediate process.

The question was, however, about "Process Id in Unix".
