Linux Processes

List all processes running that have PSAESRV and FSDMO but not FSDMO2: (including cpu and memory usage and the command that started the process): 

ps -e -o pid,%cpu,%mem,cmd | grep "PSAESRV.*FSDMO[^2]"



Update:
Use pidstat (or top) to get proper CPU usage and other details:
pidstat -p 12514 -T ALL -u -d -w -t -I

You have a couple of options: 

lsof -i tcp:80  

will give you the list of processes using tcp port 80. 

Alternatively, 

sudo netstat -nlp  

will give you all open network connections.
