The kill command is used to stop or kill a process. The command is used as follows:

kill <PID>

Here, PID is the process ID of the process running on the Linux machine.

If you need to view all the available signals that can be passed to a process, use the following command:

kill -l

Please note that the option provided with kill is the letter l and not digit 1. You will see a screen similar to the following screenshot:

Users can use kill -1 with digit 1 to force a process to reload its configuration. For example, if you want bash to reload its configuration, you can execute the following commands:

sudo su
ps -C init
kill -1 1

The output is shown in the following screenshot:

Here, we reinitialized the init process. Note that you need to be logged...
