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

ps axo rss,comm,pid | awk '{ proc_list[$2]++; proc_list[$2 "," 1] += $1; } END { for (proc in proc_list) { printf("%d\t%s\n", proc_list[proc "," 1],proc); }}' | sort -n | tail -n 10
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.
Sample Output
2472    NetworkManager
3624    getty
3888    hald
3948    nm-system-setti
3968    gdm
4012    bash
6384    sshd
14348   apache2
20560   console-kit-dae
22104   mysqld

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.
