Created August 4, 2022 09:23
cronjob running a shell script from it
  1. Need to change relative paths to absolute paths
  2. Need to replace /bin/bash to absolute reference ie. /usr/bin/bash
  3. In the crontab -e need to add following PATH to run a script 
    PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
  4. Add the PATH at the top of the shell script
  5. Now set the timer, we should be good to go.
