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
    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 It should not be used anymore, as the concept of runlevels is obsolete.
