如果进程被杀死，如何运行命令

Question

how to keep the command to run if the process is auto-killed

example:

python3 "command" then, command running if, Killed (process killed or stop) then, run the early command

Answer 1

If you want to say is: 'The process running in the terminal stopped, you want to run once in the second'. Then: 1, you can find it by the up arrow in the cursor keys of your keyboard; You can type 'sudo gedit ~/.bash_history' or 'history | less' in the terminal to see the history commands you entered.

If you want to say is: 'Your process may be stopped for some reason, but you want it to start running again' You can try this: 1, create a script to run your process; 2, in your code to find the reasons that may cause your program to stop, and then use the conditional statement to judge, once your code stops calling the script created above.
