openrc:tldr:67a4a

The given command is composed of two parts:

1. "sudo": It is used in Unix-based systems to execute a command with superuser privileges. It allows users to run programs or perform tasks that require administrative or root access.
2. "openrc ${runlevel_name}": "openrc" is a command or service management framework used in Gentoo Linux. It is responsible for starting, stopping, and managing various services during system boot.

In the command, "${runlevel_name}" is a variable that should be replaced with the actual name of the runlevel. The runlevel defines the state or mode in which the system operates. For example, runlevel 3 might represent a multi-user, non-graphical mode, while runlevel 5 could indicate a multi-user mode with a graphical interface.

So, when you run the given command with the appropriate runlevel name, it will execute the "openrc" command with elevated privileges using "sudo" to manipulate or manage services associated with the specified runlevel in your Gentoo Linux system.
