How to end a process running before connecting to the server?

Question

linux

I use a server on ubuntu for my telegram bot. I start it with nohup: nohup python3 bot.py & and usually end it with killall python3 . But now it works when there is only one bot, but when there are several of them, this approach is clearly not suitable. If I have not exited the terminal yet, then I can simply write ps, find out the pid of the process and kill it. But if I disconnect and then reconnect, then ps no longer displays this process, although it exists. How to find out his pid? Thanks in advance.

Answer 1

I agree with Fox Jovovich 's answer , but I also advise you to study the ps command
in particular, try the following options
ps a
ps axu
ps axuf | grep python3

Answer 2

man systemd. Create services for all your bots and manage them via systemctl

Answer 3

screen can be used

Answer 4

nohup python3 bot.py &
echo $!

will give the PID of the python3 process. You can throw it into a file with some kind of comment to know when to nail which one.
