Which command would you use to display network interface configuration?

The command used to display network interface configuration in Linux is ifconfig. This utility provides details about the network interfaces on a system, including their IP addresses, subnet masks, and other settings. Although ifconfig has been deprecated in some distributions in favor of the ip command from the iproute2 package, it remains a commonly recognized command for checking network configurations in many environments.

The ipconfig command is actually used in Windows systems to view similar information about network interfaces, making it inappropriate in a Linux context. The iface and netconfig commands are not standard commands in Linux for displaying network interface information and are less commonly known or used in this context. Thus, ifconfig is the most appropriate choice for viewing network configurations on Linux systems.
