`procs display` (mentioned elsethread https://news.ycombinator.com/item?id=48788167 https://news.ycombinator.com/item?id=48788167 ) supports PSS via its %M format code. One issue with that relative to RSS is permissions. Historically, all procs could see the RSS used by procs of all other users (at least if they could see the PIDs at all). So, RSS requires no special permissions, but the Linux kernel team decided PSS should not be as promiscuous for whatever reasons (I didn't do a deep dive). So, I'm always having to do (the equivalent of) `sudo pu`.
