kill: Use the kill command followed by the process ID (PID) to stop a task. First, you need to identify the PID of the task you want to stop. You can use the ps command to list the active processes, and then use kill with the appropriate signal.
To view the active processes, open a terminal and type: ps aux
Identify the PID of the process you want to stop.
To stop the process, type: kill PID (replace PID with the actual process ID)
