I'm trying to formulate a command line to give me the number of open sockets/files per process, that is, give me a list with a column with the process name and another column with the number of open sockets, can you help me with that.

ps ax | awk '{ print $1}' | xargs -i sudo lsof -p {} | egrep 'TCP|UDP'
