卡在自动运行的python程序上

Question

i tried to make autorun python script and my script is loop forever. Now i stuck on black screen, because i can't exit the python program. I followed this tutorial http://www.raspberrypi-spy.co.uk/2013/07/running-a-python-script-at-boot-using-cron/ and in this tutorial didn't including how to exit the program. Can someone tell me how to stop/kill this python program? :( i want my desktop back

Answer 1

1. Open a terminal (use [Ctrl][Alt][F2] to get to another TTY if you have to)
2. Use killall to stop the offensive program. Example: sudo killall /home/pi/MyScript.py or sudo killall /usr/bin/python
3. Remove the script from your crontab by running sudo crontab -e and removing the line from your crontab
4. Fix your script and test it thoroughly before adding it back to your crontab.

If you can't kill the script with killall , you can try:

ps aux | grep /home/pi/MyScript.py

This will return a line of information about the process, it will show the owner of the process followed by a four digit process id. You can then enter:

sudo kill [process id]

Also, if you used [Ctrl][Alt][F2] to get to another TTY, [Ctrl][Alt][F7] should take you back to your desktop.

in linux or ctr+d As with the kill and killall commands, pkill is used to send signals to processes. The pkill command allows the use of extended regular expression patterns and other matching criteria
