RUNLEVEL(8) Linux System Administrator's Manual RUNLEVEL(8)
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 sys-
tem 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, or if no runlevel record can be found, runlevel prints the word unknown and exits with an error.
Runlevel can be used in rc scripts as a substitute for the System-V who -r command. However, in newer versions of init(8) this information
is also available in the environment variables RUNLEVEL and PREVLEVEL.
OPTIONS
utmp The name of the utmp file to read.
