OK
Thank you, I got a good explanation...
But it is something that I yet don't understand:
The command (...) is composed both with
<*options* (-ld)>
and with
<*argument* "/*" or "/*/">
In my acknowledge, both the arguments of these commands ( "/*" or
"/*/")
refer to the *content of a directory*, and the -ld option should have to
select only the subdirectories.
Instead I get different output with "/*" or "/*/".
What happen really ?

In case it isn't clear, only directories will have stuff inside them
(/a/b...) so /*/ will only match directries.

And in any shell you can investigate this kind of thing like this:
echo /*
echo /*/
and see exactly what command is dipatched like this:
( set -x ; ls /* )
( set -x ; ls /*/ )
Using a subshell here purely so that the "set -x" applies only to the only
command.
