自动终止时如何重新启动任一进程

Question

i have 2 processes which needs to run simultaneously (process1 and process2-same names).

i wrote a script which will automatically restarts all the 2 processes if those 2 killed. but i am stuck at the point where if either of the process (anyone) is killed ,then the particular process not restarting.

#!/bin/bash

cd /Desktop/XYZ/

./process1 &

cd /Desktop/XYX/new/

./process1 &

while :
do

while pgrep process1 >/Desktop/XYZ/out.txt;

do

   sleep 5

done
    cd /Desktop/XYZ/

    ./process1 &

   cd /Desktop/XYX/new/

./process1 &

   sleep 10
done

any help will be greatly appreciated.

Answer 1

Just start the monitoring code too in their own subprocesses.

#!/bin/bash

while :; do
    cd /Desktop/XYZ/
    ./process1
done &

while :; do
    cd /Desktop/XYX/new
    ./process1
done &

read  # halt until it gets input
pkill -P $$  # kill all children

I have to add that this is probably not how you want to run your services longterm. You should look into how systemd service files can do this for you, or any other service manager that your system has.
