RUNLEVEL(8)                        runlevel                        RUNLEVEL(8)

NAME
       runlevel - Print previous and current SysV runlevel
SYNOPSIS
       runlevel [options...]
DESCRIPTION
       runlevel prints the previous and current SysV runlevel if they are
       known.
       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.
       Unless overridden in the environment, this will check the utmp database
       for recent runlevel changes.
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.
ENVIRONMENT
       $RUNLEVEL
           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.
FILES
       /var/run/utmp
           The utmp database runlevel reads the previous and current runlevel
           from.
NOTES
       This is a legacy command available for compatibility only. It should
       not be used anymore, as the concept of runlevels is obsolete.
