If you would like to list the size of all the directories in your current folder run the following command:

[bash]du -a -h –max-depth=1 | sort -hr[/bash]

This will provide output similar to

[bash]
69M .
36M ./plugins
16M ./.git
14M ./themes
3.4M ./uploads
8.0K ./.DS_Store
4.0K ./upgrade
4.0K ./.revision
4.0K ./index.php
[/bash]
