Which command would display Ethernet settings for a network interface?

The command that displays Ethernet settings for a network interface is ethtool. This tool is specifically designed for the querying and controlling of network driver and interface settings in Linux. It provides detailed information about the Ethernet device, including the link status, speed, duplex settings, and other driver-specific information.

Using ethtool allows system administrators and users to fine-tune network interfaces and troubleshoot issues related to Ethernet connections. It is essential for diagnosing and optimizing network performance.

While ifconfig, which is also available on many systems, can display some network interface settings, it is now considered deprecated in favor of the ip command from the iproute2 package. ipconfig is primarily used in Windows environments and does not apply here. Netstat is used for displaying network connections, routing tables, and interface statistics, but not specifically for Ethernet settings.
