Identify exact port number used by a process or app on Mac OSX

Guys, if you ever wanted to find out the exact specific port number used by a process/application on Unix/Mac OSX/Linux, type the following in Terminal :

top | awk '{print $2, $7}'

The output would be something like :

COMMAND #PORTS
awk 12
top 22+

top 19

This will show only the specific Command and Port columns from the top command and will skip other details like Process ID, % CPU utilisation , Memory usage etc.

Alternatively if you wanted to just find the port number used by a specific application, say for e.g. TextEdit, you could use the following command :

top | awk '{print $2, $7}' | grep TextEdit
TextEdit 140+
TextEdit 140

TextEdit 140

Cheers guys!
