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

It could be improved adding the "-a" switch to show also the hidden

You're only coloring the trailing / characters. If you want everything
from after the last space to the end of the line, you'd want:
tree --du -Fh /usr/local | grep --color '[^[:space:]]*/$'
I realized why "tree" command doesn't colorized the directories: "tree"
detects that its std output goes through a pipe and therefore it
disables the escaped code to colorize (like also "dmesg" does).
To avoid this behavior you must use the "unbuffer" command:
unbuffer tree --du -Fah /usr/local | grep /$
You can also try:
~# unbuffer dmesg | grep snd
/usr/bin/unbuffer is part of the "expect" package.

duhs() { printf '%s\0' "${1:-.}"/*/ | xargs -0 du -sh; }
As printf is a bash builtin, it can handle an unlimited number of
arguments. So this form should work in all cases.
Thank you very much for revolutionizing my duhs() function, but sadly
this version omits to show the hidden directories. Do you have a version
that it shows also those directories? For me it's so hard to figure out
what the "${1:-.}"/*/ block does.
Again, is "man 7 glob" the right read or do you have a better one?
