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 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 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.
