Hi Greg,
(sorry for the answer's late but I turn off the PC during the weekend) :(

I realized why "tree" command doesn't colorized the directories: "tree" 
detects that its std output goes through a pipe and therefore it 
disables the escaped code to colorize (like also "dmesg" does).
To avoid this behavior you must use the "unbuffer" command:

unbuffer tree --du -Fah /usr/local | grep /$

You can also try:

~# unbuffer dmesg | grep snd

/usr/bin/unbuffer is part of the "expect" package.

Thank you very much for revolutionizing my duhs() function, but sadly 
this version omits to show the hidden directories. Do you have a version 
that it shows also those directories? For me it's so hard to figure out 
what the  "${1:-.}"/*/  block does.
Again, is "man 7 glob" the right read or do you have a better one?
