The command tracepath -m ${max_hops} ${host} is used to trace the route that network packets take to reach a specific host on a computer network. Here is a breakdown of the command:

• tracepath: It is a command-line tool used for tracing the path of network packets.
• -m ${max_hops}: The -m option is used to specify the maximum number of hops (i.e., network routers or nodes) to be traced. ${max_hops} represents a variable that should be replaced with the desired value. For example, if you want to trace up to 10 hops, you would replace ${max_hops} with 10.
• ${host}: This variable should be replaced with the target host or IP address that you want to trace the route to. For example, if you want to trace the route to the host "example.com", you would replace ${host} with example.com.

By running this command, the system will send a series of small packets (ICMP echo requests) with an increasing Time-To-Live (TTL) value and then examine the ICMP error messages (ICMP Time Exceeded) returned by intermediate routers to determine the path taken to reach the specified host.
