SYNOPSIS

trawl is a network connection viewer that displays information about active TCP connections on a system. It shows details including local and remote addresses, connection state, and the processes associated with each connection.The watch mode provides continuous updates, refreshing the connection list at regular intervals for real-time monitoring. Connections can be filtered by process ID to focus on a specific application's network activity, and the listening-only mode shows sockets waiting for incoming connections.Output is designed to be clean and readable, with options for numeric display to avoid DNS resolution delays.
