The command "ip route show" is used to display the current routing table on a Linux-based system. It provides information about how packets should be forwarded to different destinations based on their IP address.

When the command is executed, it will list the routing table entries that the system uses to determine the next hop for a packet. Each entry contains important information such as the destination network or IP address, the gateway (or next-hop) IP address, the network interface through which the packet should be sent, and any additional flags or metrics associated with the route.

By displaying the routing table, users can easily identify how network traffic is being routed and troubleshoot any connectivity issues. It can also be used to verify the correctness of routing configurations or to check if a particular IP address is reachable through the current network setup.
