CompTIA Linux+ XK0-006 (V8) Practice Question

You stop a malfunctioning shell script (PID 4321) with kill 4321. A few seconds later you check the helper it had started:

$ ps -o pid,ppid,state,cmd -p 9876
  PID  PPID S CMD
 9876     1 S /usr/bin/python3 /opt/worker.py

What does the PPID value of 1 indicate about process 9876?

  • 9876 used exec() to replace its parent and has therefore become the session leader.

  • 9876 is now executing as a kernel thread in ring 0, so it no longer has a user-space parent.

  • The process has finished execution and is a zombie that its parent must still reap.

  • The script has exited, so the kernel re-parented 9876 to the init/systemd process (PID 1).
