rc-service:tldr:c2d41

The command sudo rc-service ${service_name} restart is used to restart a service in a Unix-like operating system using the rc-service command.

Here's a breakdown of the command:

• sudo: It is a command used to run another command with superuser privileges. It is used to execute the subsequent command with administrator or root access.

• rc-service: It is a command used in Gentoo-based Linux distributions to manage the services on the system. It is used to start, stop, restart, and manage services.

• ${service_name}: This is a placeholder syntax indicating that the actual name of the service should be substituted in its place. You need to replace ${service_name} with the actual name of the service you want to restart.

• restart: It is an option used with rc-service to specify that the specified service should be restarted.

So, when you run the sudo rc-service ${service_name} restart command, with the ${service_name} replaced by the actual service name, it will restart the specified service with root privileges.
