Introduction
A test process named labex-runaway was left running after an experiment. Its PID was recorded so an operator can target it without affecting unrelated processes.
The preceding guided lab practiced reading a PID file, inspecting that PID, sending SIGTERM, and confirming that the process stopped.
Stop the Recorded Process
Current Situation
/home/labex/project/system-recovery/runaway.pid contains the PID of one running labex-runaway process owned by labex.
Scope
- Use the PID in
runaway.pid. - Stop that process with the normal termination signal.
- Do not signal any other process.
Your Goal
Leave the recorded labex-runaway process stopped.
Acceptance Criteria
- The PID recorded in
runaway.pidis no longer running. - No unrelated process is changed.
Hints
What safe sequence did the guided lab use?
Read the PID, inspect that exact PID with ps, pass it to kill, wait briefly, and inspect the same PID again.
Summary
You safely stopped one known process by inspecting and signaling its recorded PID.
