Module on 

proc on - Port/process lookup

Usage: proc on :3000 # What process is on port 3000? proc on :3000 :8080 # What’s on several ports? (separate arguments) proc on 1234 # What ports is PID 1234 listening on? proc on node # What ports are the processes named node listening on? proc on node –cmd # … or with node anywhere in their command line proc on node –in . # Node processes in cwd and their ports

Commas still work (proc on :3000,:8080) but are deprecated.
