+.SH "OVERVIEW"
+.PP
+"Runlevels" are an obsolete way to start and stop groups of services used in SysV init\&. systemd provides a compatibility layer that maps runlevels to targets, and associated binaries like
+\fBrunlevel\fR\&. Nevertheless, only one runlevel can be "active" at a given time, while systemd can activate multiple targets concurrently, so the mapping to runlevels is confusing and only approximate\&. Runlevels should not be used in new code, and are mostly useful as a shorthand way to refer the matching systemd targets in kernel boot parameters\&.

+.SH "DESCRIPTION"
+.PP
+\fBrunlevel\fR
+prints the previous and current SysV runlevel if they are known\&.
+.PP
+The two runlevel characters are separated by a single space character\&. If a runlevel cannot be determined, N is printed instead\&. If neither can be determined, the word "unknown" is printed\&.
+.PP
+Unless overridden in the environment, this will check the utmp database for recent runlevel changes\&.
+.SH "OPTIONS"

+The following option is understood:
