## User use

To make certain files run within these automatically defined times, all you need to do is to copy the script file to the relevant directory and verify that it has ** x execution permission (chmod +x) ** . Therefore, you only need to let the system automatically run the script at one of these scheduled times, which simplifies the automation task.

Let us use cron.daily to illustrate the run process of /etc/anacrontab:

1. `anacron` reads the ** /var/spool/anacron/cron.daily ** file, and the content of the file shows the time of the last run.
1. `anacron` reads the **/var/spool/anacron/cron.daily** file, and the content of the file shows the time of the last run.
2. Compared with the current time, if the difference between the two times exceeds 1 day, the cron.daily job will run.
3. This work can only run from 03:00-22:00.
4. Verify whether a file runs after 5 minutes after booting. When the first one runs, it will be randomly delayed for 0～45 minutes to run the next one.
