netselect:tldr:0720f
The command you provided is using the "sudo" command to run the "netselect" command as a superuser (root) with elevated privileges.
Here's a breakdown of the command:
-
"sudo" is a command used in Linux and Unix-based systems to run programs with the security privileges of another user, typically the superuser (root).
-
"netselect" is a command-line utility that helps in choosing the fastest mirror from a list of mirrors for network repositories.
-
"-s" is an option/flag used with "netselect" that indicates you want the output to be in a shell script format.
-
"${N}" is a placeholder indicating that you need to provide a value for the variable "N". This value determines how many times "netselect" should test each host before ranking them.
-
"${host_1}", "${host_2}", and "${host_3}" are also placeholders for variables containing the names or IP addresses of the hosts you want to test.
To use this command, you need to replace "${N}", "${host_1}", "${host_2}", and "${host_3}" with actual values. For example:
sudo netselect -s 5 example.com host1.host.com 192.168.1.100
This command will run "netselect" five times for each host (example.com, host1.host.com, and 192.168.1.100) and produce the output in the format of a shell script.
