Go to Your Desired Cron Folder §

You can choose the folders based on their names (self-explanatory):

• /etc/cron.hourly
• /etc/cron.daily
• /etc/cron.weekly
• /etc/cron.monthly

cd /etc/cron.weekly

Create The Script File §

We just need to create a file with a descriptive name:

Let’s create a docker prune example (more info on Docker Maintenance CheatSheet and Tips).

sudo vim docker-prune

#!/bin/bash
docker system prune -f

Set the Permissions §

sudo chmod +x docker-prune

Test it §

This will run all your weekly scripts.

sudo run-parts /etc/cron.weekly
