This article introduces the knowledge of "how to use xkill commands to kill unresponsive processes in the Linux system". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

How do we kill a resource / process in Linux? Obviously we will find the pid of the resource and use the kill command.

To put it more clearly, we can find the PID of a resource (such as terminal):

The code is as follows:

$ps-A | grep-I terminal

6228? 00:00:00 gnome-terminal

In the above output, '6288' is the pid of the gnome-terminal, using the following command to kill the process.

The code is as follows:

$kill 6228

The kill command sends a signal to the process of the pid.

Another way is that we can use the pkill command, which can kill the process based on its name or other attributes. Similarly, if we want to kill a process called terminal, we can do this:

The code is as follows:

$pkill terminal

Note: the length of the process name after the pkill command is not more than 15 characters

Pkill looks easier to use because you don't have to find out the pid of the process. But if you want to have better control of the system, nothing can beat 'kill'. Use the kill command to get a better look at the process you want to kill.

For those running X Server, there is another tool called xkill that kills a process from X Window without passing its name or pid.

The xkill tool forces X server to close the connection with its client, and as a result, X resource closes the client. Xkill is a very easy-to-use tool to kill useless windows in the X11 toolset.

It supports options such as using the-display option followed by the display number to connect to the specified X server when running multiple X Server at the same time, using-all (not recommended) to kill all top-level windows on the screen, and the frame (- frame) parameter.

To list all the clients, you can run:

The code is as follows:

$xlsclients

Sample output

The code is as follows:

'' / usr/lib/libreoffice/program/soffice

Deb gnome-shell

Deb Docky

Deb google-chrome-stable

Deb soffice

Deb gnome-settings-daemon

Deb gnome-terminal-server

If you don't keep up with the resource id,xkill, it turns the mouse pointer into a special symbol, similar to "X". Just click on the window you want to kill, it will kill its communication with the server, and the program will be killed.

The code is as follows:

$xkill

It is important to note that xkill does not guarantee that its communications will be successfully killed / exited. Most programs will be killed after communication with the server is turned off. However, a small number of them will continue to run.

The points to be pointed out are:

This tool can only be used when X11 server is running, because it is part of the X11 tool.

Don't be confused when you kill a resource and it doesn't quit completely.

This is not a substitute for kill.

Do I need to use xkill on the linux command line

No, you don't have to run xkill on the command line. You can set a shortcut key and use it to call xkill.

Here is how to set keyboard shortcuts on a typical gnome3 desktop.

Go to Settings-> Select the keyboard. Click'+ 'and add a name and command. Click on the new entry and press the key combination you want. Mine is Ctrl+Alt+Shift+x.

Gnome Settin

Add shortcut key
