vtblank -- console screen saver

Synopsis

vtblank [-s seconds] [-m minutes] [-o on|off] [-v]

Description

The vtblank command is used to activate or deactivate the console screen saver by dynamically setting the TBLNK tunable, which specifies a time until the screen blanks.

Invoked without options, vtblank returns a message like the following:

   TBLNK = 40 seconds. The console-saver is enabled.
The options supported by vtblank are:

-s seconds
Sets TBLNK in seconds.

-m minutes
Sets TBLNK in minutes.

-o
Activates (-o on) or deactivates (-o off) the screen saver. Deactivating the saver does not affect the value of TBLNK.

-v
Verbose. Returns the number of seconds to which TBLNK has been set. A value of zero is returned when the featue is disabled.
The permissible range for TBLNK, in seconds, is 1-86400 (one day).

Setting TBLNK with the -s or -m options automatically overrides an earlier -o off.
