Du

Human readable du sorted by size

du is the *nix command for disk usage”). It tells you how much space everything in the given directory is taking up. GNU du introduced a handy option -h making it human readable, or showing sizes using K, M, G rather than bytes. Unfortunately this makes it not sortable numerically. Here’s how to sort du by size and keep it as human readable. Insert the following function into your .profile or .bash_profile file.
