How To Install Gdu Disk Analyzer on Ubuntu 20.04 LTS

Install Gdu Disk Analyzer on Ubuntu 20.04

In this tutorial, we will show you how to install Gdu Disk Analyzer on Ubuntu 20.04 LTS. For those of you who didn’t know, Gdu (Go Disk Usage) is very similar to Ncdu, a popular console disk usage analyzer, with one major difference: speed. Gdu makes use of parallel processing, being specially created for solid-state drives (SSD). It also works with hard disk drives (HDD), but its performance gain compared to other tools is not so great in this case.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Gdu Disk Analyzer on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.


  • A server running one of the following operating systems: Ubuntu 20.04, 18.04, 16.04, and any other Debian-based distribution like Linux Mint.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.
