Command line for looking at specific port

Here is the easy solution of port finding...

In cmd:

netstat -na | find "8080"

In bash:

netstat -na | grep "8080"

In PowerShell:

netstat -na | Select-String "8080"

Any "ESTABLISHED" socket means that there is a connection currently made there.

Any "LISTEN" means that the socket is waiting for a connection.

Both are opened ports but one is waiting for a connection to be made while the other has a connection already made.
