RaspberryPi Crontab run bash script for python in every 30 min

I wrote a bash script to check python program is running. If it's not running send me an email and start that program. After a quick research I found the solution:

creating Bash Script:

----> checkProgram.sh

#!/bin/sh

SERVICE='python'

 

if ps ax | grep -v grep | grep $SERVICE > /dev/null

then

    echo "$SERVICE service running, everything is fine"

else

    #echo "$SERVICE is not running"

    python /home/pi/receive.py &

    echo "$SERVICE is not running!" | mail -s "$SERVICE down" root

fi

CronTab:

-> crontab -e

-> */15 * * * * /home/pi/checkProg.sh

-> /etc/init.d/cron restart

This will run the program for every 15 min.
