Reboot Raspberry Pi Every Time on Schedule

Are you tired of encountering memory corruption errors on your Raspberry Pi due to the system running continuously for extended periods? Don’t worry; the solution is here! By using the Linux cron system, you can schedule your Raspberry Pi to reboot at set intervals, such as once a week or every day.

What is the cron system, you may ask? Cron is a time-based job scheduler in Unix-like operating systems. It enables users to schedule jobs, commands, or scripts to run automatically at specified times or intervals. Cron uses a crontab file to schedule tasks. A crontab file is a simple text file that contains a list of commands meant to be run at specified times.

So how do you use cron to schedule a reboot of your Raspberry Pi? It’s pretty straightforward. First, open a terminal on your Raspberry Pi and type the following command:

crontab -e

This command will open the crontab file in the default editor. If you’ve never edited your crontab file before, you’ll be prompted to choose your preferred editor.

Once the crontab file is open, you can add a new line that specifies when you want your Raspberry Pi to reboot. For example, to reboot your Raspberry Pi every day at 2:03 pm, you can add the following line:

03 14 * * * /sbin/shutdown -r now

The line above consists of five fields separated by spaces. The first two fields represent the minute and hour when you want the command to run. The third field represents the day of the month, the fourth represents the month, and the fifth represents the day of the week. In the example above, the “*” symbol means that the command should run every day of the month and every day of the week.

The final part of the line specifies the command to run, which is “/sbin/shutdown -r now” in this case. This command will reboot your Raspberry Pi immediately.

Once you’ve added the line to your crontab file, save and exit the file. Cron will automatically run the command at the specified intervals, and your Raspberry Pi will reboot accordingly.

If you’re experiencing memory corruption or other errors on your Raspberry Pi due to running continuously for extended periods, you can use the Linux cron system to schedule regular reboots.

By adding this simple line to my crontab file, I have scheduled my Raspberry Pi to reboot automatically, ensuring it runs smoothly and efficiently.
