ps_mem - Memory profiling tool
ps_mem [-h|--help] [-s|--show-cmdline] [-p PID] [-w N]
The ps_mem tool can determine how much RAM is used per program (not per process).
In detail it reports:
sum(private RAM for program processes) + sum(Shared RAM for program processes).
The shared RAM is problematic to calculate, and the tool automatically selects the most
accurate method available for the running kernel.
