Which command is used to display network configuration and routing information on a Unix/Linux system?

The command used to display network configuration and routing information on a Unix/Linux system is IFconfig. This command allows users to view and configure their network interfaces, showing details such as IP addresses, network masks, and the status of each interface. The information provided by IFconfig is crucial for troubleshooting network connectivity issues and managing network settings on Unix/Linux systems.

While other commands listed serve networking functions, they do not specifically focus on displaying network configuration in the way IFconfig does. For example, the command IPconfig is used in Windows systems, not Unix/Linux. Netstat can provide information about network connections and routing tables, but it does not specifically configure or display the settings of network interfaces like IFconfig does. Getconfig is not a standard command and doesn't apply in this context. Thus, IFconfig is recognized as the appropriate command for this task in Unix/Linux environments.
