openrc:tldr:48586
This command is used in a Unix-like operating system with the "sudo" command, which allows a user to execute a command with administrative privileges.
The "openrc" command is a service manager often used in Linux distributions that use the OpenRC init system.
The "--no-stop" flag is an option passed to the "openrc" command, which specifies that the specified runlevel should not be stopped.
"${runlevel_name}" is a placeholder for the name of the runlevel that is passed as an argument to the command. A runlevel represents a certain state in which a Unix-like operating system can operate, such as single-user mode or multi-user mode.
So, when this command is executed with administrative privileges, it tells the OpenRC service manager not to stop the specified runlevel.
