Calculate processes given a specific process name

Let's start with listing the processes of a php-fpm:

ps -C php-fpm

Display the process size:

ps -C php-fpm -o rss=

Calculate the total size:

ps -C php-fpm -o rss= | paste -s -d+ - | bc

Get the average process size:

ps -C php-fpm -o rss= | awk '{sum+=$1; count+=1} END {if (count > 0) print sum/count; else print "No processes found."}'
