I don't know, but I accidentally got to that when taking the screenshots. A full chapter of a good book on *nix can be devoted to
I'll add to crasic's response (not enough rep to comment) that if you run top, then press "z" key then "x" key top will highlight the sorted column (descending order). Then, you can then use '<' and '>' to change the sorted column (to switch between %cpu and %mem for example). hth
This will ouput pmem & rss longs of processes, worth to try.
