netstat:tldr:96c65

The command "netstat --listening --program --numeric --tcp --udp --extend" is used to display detailed information about the active network connections on a system.

• "netstat" is the command-line utility used to display network connection information in various formats.
• "--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.

By using all these options together, the command presents a detailed overview of actively listening TCP and UDP connections, including the associated processes and additional information.
