Check the memory used by a unix process


To see the memory used by the process, ps can be used with flags -AH
ps -AH v | grep 3408
where 3408 is the PID of process.

Check the column RSS (resident set size). It is the non-swapped physical memory that a task has used (in kiloBytes). (alias rssize) rsz).
