!!NAME


runlevel -- find the current and previous system runlevel.
!!SYNOPSIS


__runlevel__ [[''utmp'']
!!DESCRIPTION


__Runlevel__ reads the system ''utmp'' file (typically
''/var/run/utmp'') to locate the runlevel record, and
then prints the previous and current system runlevel on its
standard output, separated by a single space. If there is no
previous system runlevel, the letter __N__ will be
printed instead.


If no ''utmp'' file exists, or if no runlevel record can
be found, __runlevel__ prints the word __unknown__ and
exits with an error.


__Runlevel__ can be used in ''rc'' scripts as a
substitute for the System-V __who -r__ command. However,
in newer versions of init(8) this information is also
available in the environment variables __RUNLEVEL__ and
__PREVLEVEL__.
!!OPTIONS
