Which command is used to check networking settings in a Linux environment?

The command used to check networking settings in a Linux environment is ifconfig. This command is primarily used to configure, control, and query TCP/IP network interface parameters. By executing ifconfig without any arguments, a user can view the active network interfaces along with their statuses, IP addresses, subnet masks, and other related information.

While other commands like ipconfig, netstat, and route provide networking-related information, they serve different purposes or are specific to other operating systems. For instance, ipconfig is a command used in Windows to display the network configuration of the local machine, while netstat is used to display network statistics and connections. The route command is used to view and manipulate the routing table in the system. Therefore, for checking networking settings specifically within a Linux context, ifconfig is the appropriate choice.
