What is the command to show the routing table?

The command "ip route show" is used to display the routing table in Linux. This command provides a simple and clear output that lists all the routes currently configured on the system, including destination addresses, gateways, and interface information. The "ip" command is part of the iproute2 package, which has largely replaced older networking commands in modern Linux distributions. It is preferred for its comprehensive capabilities in managing network interfaces, routing, and other networking tasks.

In contrast, while "show ip route" is used in network devices like Cisco routers, it is not applicable in standard Linux command line contexts. The command "route add" is used for adding new routes to the routing table rather than displaying it. The command "netstat -r" can also show the routing table, but it is less commonly used in favor of the "ip" command due to its deprecation in some Linux distributions. Overall, "ip route show" is the correct and modern approach to view the routing table on a Linux system.
