netselect:tldr:f4763

The command "sudo netselect ${host_1} ${host_2}" is used to determine the fastest mirror server for a given host_1 and host_2 using the "netselect" tool.

Here's a breakdown of the command:

• "sudo": It is used to execute the command with administrative/root privileges. The "netselect" command requires elevated privileges to function properly.
• "netselect": It is a utility for choosing the fastest mirror from a list of public mirrors. It measures the response time of each mirror server and selects the one with the lowest latency.
• "${host_1}": It is a variable that represents the first host or mirror server to be evaluated by netselect. Replace "${host_1}" with the actual hostname or IP address of the server you want to test.
• "${host_2}": It is a variable that represents the second host or mirror server to be evaluated by netselect. Replace "${host_2}" with the actual hostname or IP address of the server you want to test.

So, by running this command, netselect will measure the response time to both host_1 and host_2, and determine which server is the fastest based on their latency.
