TrueNAS Scale is a powerful operating system that allows you to manage your data efficiently. One useful feature of TrueNAS Scale is the ability to use cron jobs to automate tasks. In this article, we will guide you through the process of finding and deleting folders that are 15 days older using cron jobs in TrueNAS Scale.

What is a cron job?

A cron job is a time-based job scheduler in Unix-like operating systems. It allows you to schedule commands or scripts to run automatically at fixed times, dates, or intervals. Cron jobs are widely used for automating repetitive tasks, such as data backups or system maintenance.

Step 1: Accessing TrueNAS Scale

To get started, you need to access your TrueNAS Scale system. Open a web browser and enter the IP address or hostname of your TrueNAS Scale server. Log in with your credentials to access the TrueNAS Scale web interface.

Step 2: Creating a new cron job

Once you are logged in, navigate to the "Tasks" tab in the top menu bar. Click on the "Cron Jobs" option in the dropdown menu. This will take you to the cron jobs management page.

On the cron jobs management page, click on the "Add" button to create a new cron job.

Step 3: Configuring the cron job

In the "Command" field, enter the command to find and delete folders that are 15 days older. The command should be in the following format:

Replace "/path/to/folder" with the actual path to the folder you want to search for and delete. The "-type d" option ensures that only folders are selected. The "-mtime +15" option specifies that the folders should be 15 days older. The "-exec rm -rf {} \;" part executes the "rm -rf" command to delete the selected folders.

Next, set the schedule for the cron job. You can choose from various options such as minutes, hours, days, etc. Select the desired schedule according to your requirements.

Finally, click on the "Submit" button to save the cron job.

Step 4: Verifying the cron job

Once the cron job is created, you can verify its status on the cron jobs management page. The status column will indicate whether the cron job is running successfully or if there are any errors.

You can also check the logs for more detailed information about the cron job execution. The logs can be accessed from the "Tasks" tab by clicking on the "View Logs" option.

Step 5: Modifying or deleting the cron job

If you need to modify or delete the cron job, you can do so from the cron jobs management page. Simply locate the cron job in the list and click on the respective buttons to edit or delete it.

It is important to note that deleting a cron job will permanently remove it, and any associated tasks will no longer be executed.

That's it! You have successfully set up a cron job to find and delete folders that are 15 days older using TrueNAS Scale. This automation will help you keep your system organized and free up storage space.

Cron jobs are an essential tool for automating tasks in TrueNAS Scale. By following the steps outlined in this article, you can easily find and delete folders that are 15 days older using cron jobs. Remember to double-check the command and schedule to ensure they meet your requirements. Happy automating!
