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.OptionsThe following option is understood:Exit statusIf one or both runlevels could be determined, 0 is returned,
a non-zero failure code otherwise.Environment$RUNLEVELIf $RUNLEVEL is set,
runlevel will print this value as current
runlevel and ignore utmp.$PREVLEVELIf $PREVLEVEL is set,
runlevel will print this value as previous
runlevel and ignore utmp.Files/var/run/utmpThe utmp database runlevel

obsolete.See Alsosystemd1,
