I have created a Cron job to run a script that checks if a process is running, in case it does it just print that the process is running, if not it prints out the process is not running and restart the process:

#!/bin/sh



SERVICE="start_server.py"

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

then

    echo "start_server.py is running"

else

    echo "start_server.py stopped"

    python2.7 start_server.py &

fi

As user Ubuntu I created the following cron job by running - crontab -e

* * * * * /home/ubuntu/mislaka/check_process.sh 2>&1 /home/ubuntu/mislaka/script_log.log

For some reason, it is not working or writing the output to the log file.

Tried restarting cron service, tried creating the cron job as root, changed all the permission and the user who is running the script yet nothing is working.

The script if I run it by itself works as expected.
