RUNLEVEL(8)runlevelRUNLEVEL(8)NAMErunlevel - Print previous and current SysV runlevelSYNOPSISrunlevel [options...]
DESCRIPTIONrunlevel 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
Prints a short help text and exits.
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not be used anymore, as the concept of runlevels is obsolete.
