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.

Usage of the port command:

port -a will show you the available ports

port -s <port> will check if that port is available to you

Examples of how to use the port command:
