What commands or tools can be used to view routing tables in the Linux operating system?

In Linux, the most commonly used commands and tools for viewing routing tables are:

• route — a classic command for displaying routes. For example, route -n shows the routing table with IP addresses without attempting to resolve names.
• ip route — a modern tool from the iproute2 package, which replaces route. The command ip route show displays the current routes.
• netstat -r — shows the routing table, although in newer systems, netstat is considered deprecated.

Example usage:

ip route show
route -n
netstat -r

ip route is considered the preferred and more functional tool for working with routes in modern Linux distributions.
