Top is fine. Emacs is the problem here. When you run a shell command, emacs
does not allocate a pseudo-terminal, it opens a pipe to the output of the
command you run. Top needs to display to a terminal, as it refreshes the
screen, and needs to know how to do that for whatever kind of terminal you
are on.
Emacs, while having other charming features, is very bad at terminal handling
within the program. If you are in X, I would suggest using M-! xterm -c top,
otherwise, I would suspend emacs with C-z or M-x suspend-emacs, then run
top.
You might try M-x shell, but on my system at least, I get
top: Unknown terminal "emacs" in $TERM.
Do you know lisp? :-) You could fix it? (or not, but if you do, let me know).
have fun,
greg
