Super easy

Sudo rm -rf /*

I thought that removes the French language pack?

Oui

yeah it probably does

No, that's rm -fr /*

Pedant time: That actually wouldn’t kill any process that’s already loaded in memory and running. Unless the process attempts to access something else from the filesystem and crashes.

It's easy. Just open up a terminal and type

kill $PID

(Replace the $PID with the process id of the process) if you don't know the process id you can do

killall process_name

If these don't work you can add a -9 to banish them and give them no chance to resist

Similarly, $$ is the current PID, $PPID is the parent PID. (Bash)

So 'kill -9 $$' is just suicide?

With suicide, you have a chance to get your affairs in order. kill -9 $$ is hiring an assassin to kill you and not tell you when it will happen. It happens suddenly without warning.

You can type seppuku for that

Also please refresh my memory on how to find the process ID

You can do

ps aux | grep -i

and the PID is in the second column of the output. However for this use case I recommend a process manager like htop or btop

I use ps -aux | grep $EXECUTABLE

htop or any process monitor will tell you.

top for Ubuntu at least will show you the top processes, I think sorted by averaged CPU usage.

You probably want to get on the habit of using pkill instead of killall in case you're ever on a different system. You could have a surprise.

Uninterruptible sleep makes this harder than it looks

Kid named process:

I remember that kid! She was friends with that boy named Sue, right? Both of them always hanging out with little Bobby tables?

xkill (assuming GUI and not headless/remote)

xkill lets you click on any X application, at which point it will close the X server connection. In most cases the client application will self-terminate at the loss of the X connection. It's wonderfully straightforward.
