With suicide, you have a chance to get your affairs in order. kill -9 $$ is hiring an assassin to kill you and not tell you when it will happen. It happens suddenly without warning.
It’s easy. Just open up a terminal and type
kill $PID
(Replace the $PID with the process id of the process) if you don’t know the process id you can do
If these don’t work you can add a
-9
to banish them and give them no chance to resistSimilarly,
$$
is the current PID,$PPID
is the parent PID. (Bash)So ‘kill -9 $$’ is just suicide?

seppuku
for thatAlso please refresh my memory on how to find the process ID
You can do
ps aux | grep -i <part of process name>
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.
