Want to see memory usage and shared memory, perhaps sorted by swap? smem -s swap -kta smem --sort swap --abbreviate --totals --autosize What about on other categories running a --sort? swap (amount of swap space consumed ignoring sharing) command (process command line) maps (total mappings count) name (process name) pid (process id #) user (process owner) pss (proportional set size including sharing) rss (resident set size ignoring sharing) uss (unique set size) vss (virtual set size; total virtual memory mapped) Bonus: A filesystem usage command to catch /tmp/ and tmpfs (temporary file storage) abusers; df -h | grep tmpfs df --human-readable | grep tmpfs
