Record Size of each directory
 

I am trying to write a script that would record the size of each of my user directories and record the output to a file to eventually be used with gnuplot. What is the easiest way to get the size of each subdirectory? For instance, I only want the total size of each individual user's directory under /home. Is there anything easier than:

(not real code, but you get the idea)
for DIR in /home/*
SIZE='du -ks $DIR'

Is a bash script the way to go? Should I use a different language?

du is probably the best for this. There are ways of doing it on other languages, but it basically comes down to the same thing really.

Thanks, that's what I figured.
