route:tldr:345fb

The given command is used to add a route entry in a Linux system's routing table using the route command with elevated privileges (sudo).

The command has the following structure:

1. sudo: Executes the command with administrative/root privileges.
2. route: The command used for managing the system's IP routing table.
3. -t: Specifies the IP version of the route to be added. In this case, it is not explicitly mentioned, so it is assumed to be the default IP version (IPv4).
4. add: Indicates that a new route entry is being added to the routing table.
5. "${destination_ip_address}/24": The network destination address and its subnet mask for which the route entry is being added. ${destination_ip_address} should be replaced with the actual IP address you want to add. The "/24" specifies the subnet mask and in this case represents a subnet with 24 bits, which translates to 255.255.255.0 subnet mask.
6. "${gateway_address}": The IP address of the gateway through which the network traffic for the specified destination will be routed. ${gateway_address} should be replaced with the actual IP address of the gateway you want to use.

In summary, this command adds a route entry to the routing table, specifying a destination IP address/network and the associated gateway for routing the traffic intended for that destination.
