The runlevel command is a Unix-based command line utility that displays the current run level of the server. Run levels are like a mode of operation that the system can be in, and they determine which jobs and daemons should run at any given time.
Unix-based systems have generally seven run levels, numbered 0 to 6. Each has a different set of services and jobs running, defined for a different mode of operations.
