Although this belongs to the Linux Command Cheat Sheet, this post is here to list all the Directory / Sub Directory and Disk drive usage
To begin with, if it is disk space you are looking for information about, the following command should display the useful disk usage information
df -h
If you want to know the size of all sub directories in a directory
Move to the directory containing the sub directories (if root, can take a long time)
du -sh *
