You can see that the same "USER" can have multiple "COMMAND"s running as "php-cgi". I would like to find out which user is running the most processes and get a count of how many processes they are running.
To count all processes per user:
ps -eo user|sort|uniq -c|sort -n
or to just have the ones running php-cgi:
ps -eo user:15,cmd|sed -n '/php-cgi/s/ .*//p'|sort|uniq -c|sort -n
