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, 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.
