RUNLEVEL
Section: Linux System Administrator's Manual (8) Updated: May 27, 1997 Index
Return to Main Contents
NAME
runlevel - find the previous and current system runlevel
SYNOPSIS
runlevel
[ utmp]
DESCRIPTION
runlevel
reads the system
utmp
file (typically
/var/run/utmp)
to locate the runlevel record, and then
prints the previous and current system runlevel on its standard output,
separated by a single space.
If there is no previous system runlevel,
the letter N will be printed instead.
If no
utmp
file exists, and if no runlevel record can be found in the
/var/run/runlevel
file,
runlevel
prints the word unknown and exits with an error.
Runlevel
can be used in rc scripts as a substitute for the Syste-V
who -r command.
However, in newer versions of init(8) this information
is also available in the environment variables RUNLEVEL and
PREVLEVEL.
