find duplicate processes

ps aux | sort --key=11 | uniq -c -d --skip-fields=10 | sort -nr --key=1,1
This command will allow to search for duplicate processes and sort them by their run count. Note that if there are same processes run by different users you'll see only one user in the result line, so you'll need to do: ps aux | grep <process> to see all users that run this command.
