Shells ports

Open ports

As a shell user there is a range of ports you may use to run services, this range is ports 5000 to 5500. (Both tcp and udp)

port command

There is a custom made command available from your shell to check which ports are in use.
This is the 'port' command.

Examples of how to use the port command:
