This video includes how you can schedule a cronjob in linux-ubuntu.
Follow these steps and create one:
1. Open the terminal and type "crontab -e" to open the cron table for editing.
2. Add a new line to the file in the following format:
"41 11 * * * [according to video]"
where the five asterisks represent the minutes (0-59), hours (0-23), days of the month (1-31), months (1-12), and the day of the week (0-7, where both 0 and 7 represent Sunday) respectively, on which the command should be executed.
3. Save the file and exit the editor.
4. The cron job is now set up and will run at the specified time (11:41am).
To see the cron job list type "crontab -l"
To remove the cron job type "crontab -r"
