It will show the processes hogging more memory and the user they belong to. Maybe you want something different: the sum of all the processes belonging to one user. In that case I think a little script is needed. Here is my ugly attempt: ps ww -e --sort -rss o user=,rss=,pid=,pmem=,command=,size=,vsz=\ |(sort; echo)\ |gawk '{if ( lastuser == $1 ) {tot=tot+$2} \ else {printf "%9i %s\n",tot,lastuser; tot=$2}; lastuser=$1 }'|\ sort -nr Best regards. -- Roberto Ragusa mail at robertoragusa.it
