i am not in disagreement with this as i used *unix* in it's early form. my early unix
manuals are buried too deep to get to, so i can not quote from them or find when
change came about.

but this is not *unix*,  we are discussing *linux*. in *linux*, the command 'su' is
'substitute user or group'.

in *linux*, 'su' gives a user who knows 'root' password, ability to become _any_user_
or a member of _any_group_. therefore, i again say, command 'su' is not 'super user'.

so if i give command 'su poc' or 'su paul', i do not become a 'superuser'. i simply
become user 'poc' or user 'paul'.

*msdos* systems and *ms windows* have very little concept of anything.
