To schedule a task using

Here’s an example of how you can use
crontab to schedule a task:
- Open a terminal and type the following command to edit your crontab file:
- This will open the crontab file in a text editor. Add a line to the file with the following format:
minute hour day-of-month month day-of-week command
- The first five fields represent the schedule, and the sixth field is the command you want to run. For example, to run a command at 10:30 every day, you would enter the following line:
30 10 * * * command
- Save and exit the text editor.
cronwill now run the command at the specified time.
You can use the
crontab -l command to view your current crontab file, and the
crontab -r command to remove it.
