How to install NCDU on Ubuntu 17.04

NCDU or NCurses Disk Usage is a command line tool to view and analyse disk space usage on Linux. It can drill down into directories and report space used by individual directories. It allows the user to do much faster than a GUI file manager. This tutorial explains the installation procedure of NCDU on Ubuntu 17.04.

Installation procedure

root@linuxhelp1:~# add-apt-repository ppa:eugenesan/ppa
This repository contains collection of customized, updated, ported and backported
packages for two last LTS releases and latest pre-LTS release.
Packages for older releases relocated to ppa:eugenesan/archive or deleted.
