runlevel



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, 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.


SEE ALSO

       init(8), utmp(5)
