The command used to view detailed information about network interfaces is "ip link show." This command is part of the iproute2 suite, which is a modern set of networking utilities designed to provide more advanced features and better control over networking compared to older tools. When you run "ip link show," it lists all network interfaces along with crucial details such as their names, statuses (up or down), and associated hardware addresses (MAC addresses). This makes it a very effective choice for obtaining comprehensive information about the network interfaces on a system.

The other commands do not serve the specific purpose of viewing network interface details in the same way. "ifconfig" is an older command that also provides information about network interfaces, but it is being gradually deprecated in favor of the ip command. "wget" is used for downloading files from the web and has no relation to network interface details. "traceroute" is primarily used for diagnosing the route packets take to reach a specific destination, rather than providing information about local network interfaces. Therefore, "ip link show" stands out as the most appropriate command for accessing detailed information about network interfaces.
