RUNLEVEL linux command manual
RUNLEVEL(8) Linux System Administrator's Manual RUNLEVEL(8)
NAME
runlevel -- find the current and previous 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, or if no runlevel record can be found, run-
level 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 informa-
tion is also available in the environment variables RUNLEVEL and PRE-
VLEVEL.
OPTIONS
utmp The name of the utmp file to read.
