Looks like both your user and the root user are executing saytime.sh at 8PM. Did you set this up using crontab?
Each user has their own crontab. If you execute sudo crontab -e then you are editing the crontab for the root user. If you execute crontab -e then it is just for your user. Can you make sure that you don’t have the command in both places?
I will check both but yes I did use sudo crontab -e to edit the cron. Thanks for replying. I tried checking the crontab using /var/spool/cron/crontabs but it said permission denied.
