Mac – find which process is listening on a port

We can use lsof or netstat to find which process is listening on a port. Here are the steps:

1. To see which process is listening on port 8080 using netstat
   sudo netstat -anv | grep [.]8080
   

   tcp4       0      0  127.0.0.1.8080         *.*                    LISTEN      131072 131072  48921      0 0x0100 0x00000106

2. To see which process is listening using lsof
   sudo lsof -i :8080
   or
   sudo lsof -i -P | grep LISTEN | grep :8080
3. Once you get the process id, use the ps command to see its name
   ps -f -p 48921
