Bash script to check if a process is running and if failed, restart it

Thanks to Karson for this one.

Create a file:

sudo nano ./run.sh

#!/bin/sh
if ps -ef | grep -v grep | grep boinc ; then
exit 1
else
sudo systemctl restart boinc-client &
exit 0
fi

Change permissions

sudo chmod +x ./run.sh

Make it run automatically

crontab -e

Every second

* * * * * /home/user/run.sh
