size of every www folder in users' home

I need to make a shell script to get the size of every www directory of my users home folder

I need开发者_如何学运维 somethings like
USERNAME - WWWdirsize
USERNAME - WWWdirsize
TOTAL www Size = ...

I know that I have to play with the du unix command

any help?

To get the recursive size of a folder: du -hs | cut -f 1

So to get the size of each user's www folder:

ls /home | while read username; do echo "$username $(du -hs "/home/$username/public_html" | cut -f 1)"; done

Try something like this:

du -sh /home/*/public_html

Output on my system:

0       /home/brokeneggs/public_html
3.1G    /home/jonhall/public_html
178M    /home/stubuntu/public_html

You can do further parsing of the output if you want only usernames to appear, and not full paths, for instance.

try this command to calculate:

du -sch .
