NCurses Disk Usage
This tool will allow you to see how much disk space each directory is using. It will run from which ever current directory you are running it from. It is really useful to find out where your disk space is going and what is using it.
From the site
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 gaphical 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.
apt-get install ncdu
