How to use linux's kill command to kill a process

Today, the editor shares with you how to use linux's kill command to kill the process. I believe many people do not know much about it. In order to make you understand better, I have summarized the following contents for you. Let's look down together. I'm sure you'll get something.

Kill, as the word means, means to kill. The kill command in a linux system is used to delete a program or work in progress.

The kill command sends a specified signal to the appropriate process or work. The kill command uses a signal of 15 by default, which is used to end a process or work. If the process or work ignores this signal, you can use signal 9 to force the process or job to be killed.

Syntax format: kill [parameters] [process number]

Common parameters:

-l lists the signals supported by the system-s specifies the signal sent to the process-a does not restrict the correspondence between the command name and the process number when processing the current process-p specifies that the kill command only prints the process number of the relevant process and does not send any signal

Reference example

List the signals supported by the system:

[root@linuxcool ~] # kill-l

Find the process and kill it with kill:

[root@linuxcool ~] # ps

PID TTY TIME CMD

1951 pts/0 00:00:00 bash

2446 pts/0 00:00:00 ps

Check that the process ID of bash is 1951, and then enter:

[root@linuxcool] # kill-9 1951
