Yes, i don't understand what is a directory according to the behavior of
this command:
What the $ dired command should do when i run it on the root (/) of my
system and the cursor is on say /bin?
Actually it hide all, and and M-$ does the same.

So what these $ and M-$ are for?

for me actually, they hide all files and subdirs in all case.

Sorry for my difficulty to understand that, but that still very unclear
for me.

Here a directory:(is it?)

What should show $ if my cursor is on say Consolekit (a subdirectory of
/etc right?) ?

What should show M-$ (cursor anywhere)?
