    ps_mem

    A utility to accurately report the core memory usage for a program

    Yes the name is a bit weird. coremem would be more appropriate, but for backwards compatible reasons the ps_mem name remains.

    Install:

    pip install ps_mem is supported, or rpm and deb packages are available for most distros. Also the ps_mem.py script can be run directly.

    Usage:

    ps_mem [-h|--help] [-p PID,...] [-s|--split-args] [-t|--total] [-w N]
           [-d|--discriminate-by-pid] [-S|--swap]
    

    Example output:

     Private  +   Shared  =  RAM used       Program
    
     34.6 MiB +   1.0 MiB =  35.7 MiB       gnome-terminal
    139.8 MiB +   2.3 MiB = 142.1 MiB       firefox
    291.8 MiB +   2.5 MiB = 294.3 MiB       gnome-shell
    272.2 MiB +  43.9 MiB = 316.1 MiB       chrome (12)
    913.9 MiB +   3.2 MiB = 917.1 MiB       thunderbird
    ---------------------------------
                              1.9 GiB
    =================================
    

    The [-p PID,...] option allows filtering the results. For example to restrict output to the current $USER you could:

    sudo ps_mem -p $(pgrep -d, -u $USER)
    

    or to summarize the total RAM usage per user you could:

    for i in $(ps -e -o user= | sort | uniq); do
      printf '%-20s%10s\n' $i $(sudo ps_mem --total -p $(pgrep -d, -u $i))
    done
