Updated top ten memory utilizing processes (child/instance aggregation) now with percentages of total RAM

Prints the top 10 memory consuming processes (with children and instances aggregated) sorted by total RSS and calculates the percentage of total RAM each uses. Please note that since RSS can include shared libraries it is possible for the percentages to add up to more that the total amount of RAM, but this still gives you a pretty good idea. Also note that this does not work with the mawk version of awk, but it works fine with GNU Awk which is on most Linux systems. It also does not work on OS X.

I like it, but I want it reversed. I put "tac" at the end.

TR=`free|grep Mem:|awk '{print $2}'`;ps axo rss,comm,pid|awk -v tr=$TR '{proc_list[$2]+=$1;} END {for (proc in proc_list) {proc_pct=(proc_list[proc]/tr)*100; printf("%d\t%-16s\t%0.2f%\n",proc_list[proc],proc,proc_pct);}}'|sort -n |tail -n 10 | tac

Or, you can change "sort -n|tail -n 10" to "sort -nr|head -n 10" if you want it reversed.

I added a column description by adding this line in front.

printf "%-7s\t%-16s\t%-4s\n" RSS COMMAND RSS%;

You need to change %0.2f% to %0.2f in the second awk, my system wouldn't run the command until I fixed it.
