ncdu is an excellent way to look at disk space usage on a linux based system. Ncdu is a disk usage analyzer with an ncurses interface. It is designed to find space hogs on a remote server where you don't have an entire graphical setup available, but it is a useful tool even on regular desktop systems. Ncdu aims to be fast, simple and easy to use, and should be able to run in any minimal POSIX-like environment with ncurses installed.

From the command line (you will need to have epel-releases installed, or you won't find the repositories).

  yum install ncdu

Once installed you can launch the application from the command line using:

  ncdu

Below is an example of ncdu running on a packager v8.
