Can netstat show process names?

Yes, netstat can show process names, but this capability depends on the operating system and the specific options used.

On Linux, you can use the -p option with netstat to display the process ID and the name of the program using the socket:

netstat -nlp

On macOS, netstat does not directly show process names. Instead, you can use lsof to achieve this:

lsof -P -i :<port_number>

On Windows, you can use the following command to see the process ID, and then you can match it with the process name using Task Manager or another command:

netstat -ano

If you need to find the process name associated with a specific port, using lsof on macOS/Linux is generally more straightforward.
