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 It should not be used anymore, as the concept of runlevels is obsolete.
