The route command in a Linux environment is specifically designed to display the host's routing table. This table provides critical information about the paths available for network traffic and how data packets are routed from one network to another. It shows destination networks, gateway addresses, network interfaces, and the metrics used to determine the best route for data transmission.

Understanding the routing table is essential for network configuration and troubleshooting, as it helps network administrators and users verify that the system has the correct configurations to communicate with other devices on the network. The information displayed by the route command can be essential when diagnosing connectivity issues or optimizing network performance.

The other choices do not pertain to the function of the route command. Active users would relate to commands like 'who' or 'w,' current system date and time can be displayed with the 'date' command, and disk usage statistics are shown by tools like 'df' or 'du.' Therefore, the definition of the route command's functionality aligns directly with displaying the host's routing table.
