How to terminate useless processes in Linux system?

We can close processes that are not used in the Linux system. Let’s take a look at the detailed tutorial below.

This article describes how to shut down a process in the Linux operating system.

1. Open the ubuntu operating system, ctrl alt t -> Enter the terminal.

2. Enter ps, the command is used to view the currently running processes.

3. Currently, there are three processes under this terminal: bash, a.out, ps

PID TTY TIME CMD

2745 pts/1 00:00:00 bash

3960 pts/1 00:00:00 a.out

3961 pts/1 00:00:00

ps We will close the a.out process.

4. Find the process number of the a.out process through ps PID is 3960

kill -s 9 3960

You can close a.out. If you want to close other processes, just replace 3960 with the process number of other processes.
