Determine Total Size of Directory (Folder) in Bash

Determine Total Size of Directory (Folder) in Bash

Hello today I will be showing you how to determine the total size of a directory in bash or any other Unix-like shell. I am using Ubuntu 20.04 in this video, although all Unix-like OS will work. I intentionally created this video so it would be very quick and simple, and NOT to show too many options/features. Just to get right to the point.
