What's the program that lets me click on a window to kill it? Can't remember...
 

Maybe I'm dreaming - but I remember there was either a command or a program, or shortcut, that I could use and it would allow me to click on a window in linux, and that window would be killed....

Is that true? Does anyone remember or know what it is?

Thanks,

In Gnome, the Force Quit panel utility does exactly that. To add it, right click on any gnome panel, select "Add to panel..." and add the "Force Quit" applet. When you want to use it, click on its icon and then click on the application you want to kill.

xkill? Apparently I have to write at least 100 characters.

xkill does that as well, on any window manager.
Launch xkill from a terminal or create a shortcut.

Edit: too late...

or you can kill the command from the terminal.

do a ps ax |grep programname

for example:

[16:56][root@francoisvn]~ # ps ax |grep ssh
2090 ? Ss 0:00 /usr/sbin/sshd
21383 ? Ss 0:00 /usr/bin/ssh-agent /usr/bin/dbus-launch --exit-with-session gnome-session
21623 pts/2 S+ 0:00 ssh -C francoisvn@*****
21645 pts/3 S+ 0:00 ssh -C francoisvn@*****
21669 pts/4 S+ 0:00 ssh -C user@*****
24187 pts/1 S+ 0:00 ssh -C root@*****
24411 pts/0 S+ 0:00 grep ssh
[16:57][root@francoisvn]~ #

Then kill that process, for example

kill -s sigkill 21645

Pressing control alt and esc at the same time should bring the x kill x up also :)
This is only good for an app thats presently showing on the desktop so that you can place the x cursor over it and kill it.

control + esc will give you a list of running processes. Find the one you want to kill and click on it.

As a last resort, click control + alt + esc. You will see your cursor symbol replaced by a skull and crossbones icon. If you then click on any window it will kill it instantly. But use with care!

"ctrl + esc" and "ctrl + alt + esc" doesn't work for me. Is that a window manager specific configuration ?

Rognon - I'm using KDE 3.5.9.

In my system too, the combinations do not work. Mine is 2.6.24-16-generic.
Do anyone know what keys should be used in this version to kill processes?

The CTRL+ALT+ESC combination does not work when I am using Compiz-fusion on Mandriva 2008, I just created a shortcut on my panel (or you can edit the shortcut keys in compiz-fusion to run the xkill command)
