4.6.3. Scheduling

• Use sleep to create a reminder that your pasta is ready in ten minutes.

• Create an at job that copies all files in your home directory to /var/tmp within half an hour. You may want to create a sub-directory in /var/tmp.

• Make a cronjob that does this task every Monday to Friday during lunch.

• Check that it works.

• Make a mistake in the crontab entry, like issuing the nonexistent command coppy instead of cp. What happens upon execution of the task?
