That's a little cold. Give the guy a bit of a hint, as in
run "truss" on a command that reports one or more of what you
want. (You'll have to be root if the command is setuid; if you don't
have root, you don't have any business trying to write stuff to do
these things anyway.) Swap is easy, see swapctl(2). File system
type and size can be obtained with statvfs(2) (which df(1) uses),
but statvfs does _not_ provide utilization or performance info
(hint: truss iostat;man kstat). Hardware type name is really easy,
so I won't quite tell you the system call (hint: truss uname).
If it's literally homework, I left the slacker a tiny bit yet to do,
esp. on the filesystem utilization info. :-) If it's not, and this
is just a case of clueless trying to get a clue, well that _is_ one
of the reasons people come here...
