Which command is used to display and manipulate route and device options?

The command used to display and manipulate routing and device options is "ip route." This command is part of the iproute2 package that has largely replaced older commands like "route" and "ifconfig" in modern Linux distributions.

Using "ip route," you can view the current routing table, add new routes, delete existing routes, and change route configurations. This command allows for more comprehensive capabilities in terms of network management compared to previous tools, as it encompasses a wider array of networking functionalities through a single command structure. For example, with the "ip route" command, you can see the routes available on the system, check interface configurations, and even manage advanced routing scenarios.

While "route" is an older command that can still display routing information, it lacks many of the advanced features and flexibility offered by the "ip route" command. Additionally, "network-config" is not a standard command found in most Linux distributions, and "netstat," while useful for showing network statistics and connections, does not specifically manipulate routing options or device configurations. This makes "ip route" the preferred choice in the context of managing routing tables in a Linux environment.
