The command "ip rule ${select}" is used to manipulate the routing policy database in Linux. It allows you to set rules that determine which route will be used for outgoing packets based on certain conditions.

Here, "${select}" represents the specific rule or condition that you want to define. It could be a number indicating the priority order of the rule, an IP address, a network interface, etc. The value of "${select}" will determine how the routing decision is made.

By using this command, you can create complex routing configurations and control how network traffic is handled. It helps you define specific routing behaviors based on different conditions or requirements.
