Top ten (or whatever) memory utilizing processes (with children aggregate)

This command loops over all of the processes in a system and creates an associative array in awk with the process name as the key and the sum of the RSS as the value. The associative array has the effect of summing a parent process and all of it's children. It then prints the top ten processes sorted by size.

Alternatives

There are 5 alternatives - vote for the best!

Terminal - Alternatives
ps axo rss,comm,pid | awk '{ proc_list[$2] += $1; } END { for (proc in proc_list) { printf("%d\t%s\n", proc_list[proc],proc); }}' | sort -n | tail -n 10

What others think

Great command. Just wondering if it would be possible to enter this into an alias, or a one liner script.. I got awk syntax errors trying to do so with both commands above - Pasted below but not sure how well it will get formatted.

awk: { proc_list[on]++; proc_list[on , 1] += rmstar; } END { for (proc in proc_list) { printf(%dt%sn, proc_list[proc , 1],proc); }}

awk: ^ syntax error

awk: { proc_list[on]++; proc_list[on , 1] += rmstar; } END { for (proc in proc_list) { printf(%dt%sn, proc_list[proc , 1],proc); }}

awk: ^ syntax error

You may be able to do it with an alias command, but you'll need to escape the quotes.
