NAME¶runlevel - Print previous and current SysV runlevel
OVERVIEW¶"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 runlevel. 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.

OPTIONS¶The following option is understood: --help
Print a short help text and exit.
EXIT STATUS¶If one or both runlevels could be determined, 0 is returned, a non-zero failure code otherwise.
If $RUNLEVEL is set, runlevel will print this value as current runlevel and ignore utmp.$PREVLEVEL
If $PREVLEVEL is set, runlevel will print this value as previous runlevel and ignore utmp.
The utmp database runlevel reads the previous and current runlevel from.
