How To Check Disk Space Usage With Ncdu Utility

Check Disk Space Usage With Ncdu Utility

In this tutorial, we will show you how to check disk space usage with ncdu utility on your Linux server. For those of you who didn’t know, Ncdu (NCurses Disk Usage)  is a command-line tool to view and analyze disk space usage on Linux. It can drill down into directories and report space used by individual directories. This way it is very easy to track down space-consuming files/directories.

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 Ncdu on Linux systems.

Prerequisites

  • A server running one of the following operating systems: CentOS Linux.
  • 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.
