pretty version of df(1) command
Discus aims to make df prettier, with features such as color, graphs, and smart formatting of numbers (automatically choosing the most suitable size from kilobytes, megabytes, gigabytes, or terabytes). If you don't want Discus deciding the best sizes, you can also choose your own increments, along with specifying the number of decimal places you'd like to see.
