Killing python script in background

[faramon]

Greeting,
what is the way I could kill python script that raises on reboot or restart, (Raspbian Jessie)?
Startup goes to location /home/pi/.config/autostart and over myPiAutostart.desktop script opens python script.
The desktop file contains:
[Desktop Entry]
Type = Application
Name = MyPiAutostart
Exec = sudo python2 /home/pi/myPiConfig/checkGPIOstatus.py
StartupNotify = false
Name [hr_HR] = MyPiAutostart

I tried starting in the background with & symbol: Exec = sudo python2 /home/pi/myPiConfig/checkGPIOstatus.py &

How can I kill a script that is active in the background if I have a need sometimes to kill?
I cant even know PID for killing, task manager does not show my script in back processes...

Thanx in advance,
Faramon

ps axOT
will show all processes sorted by time
sudo kill -9 PID of the offending script
if you have a looped process .... i.e. a script that calls the program repeatedly on exit then kill that process first then the one you want

From a terminal

ps aux | grep python

should show the PID.

Alternatively

sudo killall python2

will kill all Python scripts started with the command python2.

Yes, i do have LOOP in python script.

I'll try your solution...

I try
ps aux | grep python
and i found in given processes my PID.

Then in terminal i try
sudo kill -9 MyPID
and this works, thanx.

I did not try second given solution but thanx, someone maybe found it usefull.

Thanx,
Faramon
