Which command in Linux is primarily used to check the status of network interfaces?

The command primarily used to check the status of network interfaces in Linux is ifconfig. This command is part of the net-tools package and provides information about network interfaces, including their status, IP address, MAC address, and other important network configuration details. By executing ifconfig, users can see which interfaces are active, their respective configurations, and whether they are up or down.

This command is particularly useful for network troubleshooting and configuration. Although other commands may provide network-related information, none are as specifically tailored to display the detailed status and configuration of network interfaces as ifconfig.
