I've some issue with this function. It doesn't show the size of the 
directory specified as argument, it follows the output of my original 
function:

duhs1() { IFS=$'\n\r' ; for d in $(/usr/bin/find $1 -maxdepth 1 -type d 
|/usr/bin/sort) ; do du -hs $d ; done }

~# duhs1 /usr/local/
88K     /usr/local/     ←←←
4,0K    /usr/local/bin
4,0K    /usr/local/etc
...

According to the very kind Greg's explanation I tried to change the 
function in this way:

duhs() {
     (
       shopt -s dotglob
       du -sh "${1:-.}"
       printf '%s\0' "${1:-.}"/*/ | xargs -0 du -sh
     )
}

the specified directory is shown, but the output has became messed up:

~# duhs /usr/local/
88K     /usr/local/
4,0K    /usr/local//bin/
4,0K    /usr/local//etc/
4,0K    /usr/local//games/
4,0K    /usr/local//include/
4,0K    /usr/local//man/
4,0K    /usr/local//sbin/
56K     /usr/local//share/
4,0K    /usr/local//src/

and worst the size of /usr/local/share isn't 56K:

~# du -hs /usr/local/share/
60K     /usr/local/share/

as it's shown by my original function:

~# duhs1 /usr/local/
88K     /usr/local/
4,0K    /usr/local/bin
4,0K    /usr/local/etc
4,0K    /usr/local/games
4,0K    /usr/local/include
4,0K    /usr/local/sbin
60K     /usr/local/share
4,0K    /usr/local/src

the /usr/local/man/ isn't listed by the "find" command because it's a 
symlink:

~# ls -l /usr/local/man
lrwxrwxrwx 1 root root 9 21 giu  2023 /usr/local/man -> share/man

Is there a way to have duhs() function that it doesn't print a double 
"/" at the end of the specified directory?
The size mismatch of /usr/local/share could depend by /usr/local/man is 
a symlink of 4K's size to a directory embedded in /usr/local/share, am I 
right?
