The application you are referring to is called shutdown. It is a command-line tool in Unix-like operating systems that handles shutdown, reboot, and halt operations, including stopping jobs and forcefully killing applications.
Here is a simple example of how to use shutdown to forcefully kill a process:
# Replace 'pid' with the Process ID of the application you want to kill
shutdown -k -p -s now pid
-k: Send a warning message to the system console and log the event to the system log.-p: Power off the system immediately after the warning message is sent.-s: Shutdown the system.now: Perform the action immediately.pid: The Process ID of the application you want to kill.
