runlevel -- find the current and previous system runlevel. |

!!SYNOPSIS |

__runlevel__ [[''utmp''] |

!!DESCRIPTION |

__Runlevel__ reads the system ''utmp'' file (typically |
| |
|
22 |
''/var/run/utmp'') to locate the runlevel record, and |
| |
|
23 |
then prints the previous and current system runlevel on its |
| |
|
24 |
standard output, separated by a single space. If there is no |
| |
|
25 |
previous system runlevel, the letter __N__ will be |
| |
|
26 |
printed instead. |
| |
|
27 |
|
| |
|
28 |
|
| |
|
29 |
If no ''utmp'' file exists, or if no runlevel record can |
| |
|
30 |
be found, __runlevel__ prints the word __unknown__ and |
| |
|
31 |
exits with an error. |
| |
|
32 |
|
| |
|
33 |
|
| |
|
34 |
__Runlevel__ can be used in ''rc'' scripts as a |
| |
|
35 |
substitute for the System-V __who -r__ command. However, |
| |
|
36 |
in newer versions of init(8) this information is also |
| |
|
37 |
available in the environment variables __RUNLEVEL__ and |
| |
|
38 |
__PREVLEVEL__. |
