A me, con bash, %blow non rende nulla, a parte quanto ci si puo` aspettare.

Per tar, carino il messaggio. Diverso dal solito.

Provate con

man su

e leggete cosa pensa Richard Stallman del gruppo wheel.

Dentro man su effettivamente non c'e` nulla. Ma in compenso c'e` dentro info su:

22.5.1 Why GNU `su' does not support the `wheel' group
------------------------------------------------------

(This section is by Richard Stallman.)

Sometimes a few of the users try to hold total power over all the
rest. For example, in 1984, a few users at the MIT AI lab decided to
seize power by changing the operator password on the Twenex system and
keeping it secret from everyone else. (I was able to thwart this coup
and give power back to the users by patching the kernel, but I wouldn't
know how to do that in Unix.)

However, occasionally the rulers do tell someone. Under the usual
`su' mechanism, once someone learns the root password who sympathizes
with the ordinary users, he or she can tell the rest. The "wheel
group" feature would make this impossible, and thus cement the power of
the rulers.

I'm on the side of the masses, not that of the rulers. If you are
used to supporting the bosses and sysadmins in whatever they do, you
might find this idea strange at first.
