How to Install Duf on Debian 12

---

Duf also called "Disk Usage Free utility" is a free and open-source tool written in Golang. It is used to display disk usage of the system in a tabular format. It is an alternative to the df command and it can be installed on Linux, BSD, Windows, and macOS. It also displays the disk usage details in the JSON output.

In this post, we will show you how to monitor disk usage with the Duf utility on Debian 12.

Prerequisites

---

• A system with Debian 12 installed and running.

• root access to the system.

Check for System Updates

---

First, we will update the system to the latest with the following commands,

apt update
apt upgrade

Install Duf

At the time of writing this article, version 0.8.1 was the latest. You can check and download the latest version of .deb source file from their official repository.

We will download using wget command as shown below,

wget https://github.com/muesli/duf/releases/download/v0.8.1/duf_0.8.1_linux_amd64.deb
