Xiaobian to share with you how to use Cron and Crontab timing tasks in Raspberry Pi, I hope you have gained something after reading this article, let's discuss it together!

Raspberry Pi-Cron and Crontab (timed tasks)

Cron is a tool for configuring periodic tasks on Unix systems, used to execute commands or scripts periodically or at certain intervals; the range of tasks that can be executed can be automatic backup of the user's home folder every night, or it can record CPU information logs every hour.

The crontab (cron table) command is used to edit the list of recurring tasks in progress, and the action is per-user, with each user (including root) having its own crontab.

EDITING CRONTAB

Run crontab and-e option to edit cron table:

crontab -eSELECT AN EDIROR

The first time you run crontab you will be prompted to select an editor. If you are unsure which one to use, you can simply press Enter to select the default nano editor.

Each cron entity contains six parts: the minute, the hour, the day of the month, the month of the year, the day of the week, and the timed command.

# m h dom mon dow command# *** * command to execute##<$<$<$<$<$(From 0 to 6 for Sunday to Saturday, names can also be used; 7 is Sunday, Equivalent to 0)#

For example:

0 0 * * * /home/pi/backup.sh

This cron instance will execute the backup.sh script every day at midnight.
