- "--listening" option filters the output to only show the listening sockets, which are the ones actively listening for incoming connections.
- "--program" option displays the program name or process ID associated with each connection.
- "--numeric" option displays the IP addresses and port numbers as numeric values instead of resolving them to their corresponding hostnames or service names.
- "--tcp" option filters the output to only show TCP (Transmission Control Protocol) connections.
- "--udp" option filters the output to only show UDP (User Datagram Protocol) connections.
- "--extend" option provides extended information about the connections, such as the user owning the process and the state of the connection.
