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 ?
