Fair enough.  

Did you intend to suggest "ps -F"?  While ps remains not-so-well
standardized, I know of no version where "ps -Af" details *memory*
usage.

Parsing can be simplified with such invocations as
    ps -o pid -o rss -o size -o cmd
(which can itself be rewritten in various ways, depending on the
flavor of ps involved).
