In OpenRC, runlevels are used to define the state of the system and the services that should be running at any given time. rc-status is a command-line tool that provides information about the current state of the system and the services running in each runlevel.
When run without any arguments, rc-status displays a summary of the current system state. This includes the current runlevel, the services that are running, and the services that are scheduled to start or stop.
rc-status also allows you to specify one or more runlevels as arguments. For example, rc-status default will display information about the default runlevel, while rc-status boot local will display information about the boot and local runlevels.
In addition to displaying information about the current system state, rc-status can also be used to check the status of individual services. You can use the -a option to display information about all services, or you can specify one or more service names as arguments. For example, rc-status sshd will display information about the sshd service.
One of the useful features of rc-status is its ability to display service dependencies. When run with the -d option, rc-status will display a tree diagram showing the dependencies between services. This can be useful for troubleshooting startup problems or understanding how different services are related to one another.
Overall, rc-status is a powerful tool for managing and troubleshooting OpenRC services, and it can provide valuable insights into the state of your system and the services running on it.
