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.
