Ports are somewhat like doors, traffic can flow either way though them but you can set them up so that it can only flow one way. A listening port is open and waiting for something to come in. It is possible to configure things so that a port can be used to receive traffic, but not send anything out through it. It is also possible to configure things so that a port is not listening but it is open for SENDING out information. Usually when we speak of an "open port" it is open for traffic both ways.

Is portal id and ip address same?
They are not the same; a port number indicates a listening program that will receive a packet. That number exists on the target system, but the port number itself has no identification that would allow a packet to be routed or delivered to it. An IP address identifies a system on a network for delivery purposes. Once the packet arrives, however, it has to be given to an appropriate program listening for a protocol. that is what the port number is for.

You wouldn't use a shell script to do this. Any program could listen on a port by connecting or binding to a socket address. There are some utility languages such as Perl that could connect to a port and listen, but the listening would also be a function of what you are listening for.
