.Dd August 6, 2013 .Dt VERSION.4TH 8 .Os .Sh NAME .Nm version.4th .Nd FreeBSD version string boot module .Sh DESCRIPTION The file that goes by the name of .Nm is a set of commands designed to draw the boot loader version at the bottom-right of the screen. The commands of .Nm by themselves are not enough for most uses. Please refer to the examples below for the most common situations, and to .Xr loader 8 for additional commands.
p Before using any of the commands provided in .Nm , it must be included through the command:
p .Dl include version.4th
p This line is present in the default
a /boot/menu.rc file, so it is not needed (and should not be re-issued) in a normal setup.
p The commands provided by it are:
p l -tag -width disable-module_module -compact -offset indent t Ic print_version Prints the contents of the .Va loader_version environment variable right-justified at the column .Va loader_version_x and row .Va loader_version_y . .El
p The environment variables that effect its behavior are: l -tag -width bootfile -offset indent t Va loader_version Set automatically by .Xr loader 8 , but you can override it by setting in .Xr loader.conf 5 . This should be the version of boot loader used. t Va loader_version_x Sets the desired ending column position of .Va loader_version . Default is 80. t Va loader_version_y Sets the desired ending row position of .Va loader_version . Default is 24. t Va loader_color If set to .Dq Li NO (case-insensitive) or .Dq Li 0 , causes the version to be printed without color
q default is ANSI Cyan . .El .Sh FILES l -tag -width /boot/version.4th -compact t Pa /boot/loader The .Xr loader 8 . t Pa /boot/version.4th .Nm itself. t Pa /boot/loader.rc .Xr loader 8 bootstrapping script. .El .Sh EXAMPLES Override .Xr loader 8 version in .Xr loader.conf 5 :
p d -literal -offset indent -compact loader_version="loader 1.1" .Ed .Sh SEE ALSO .Xr loader.conf 5 , .Xr color.4th 8 , .Xr loader 8 .Sh HISTORY The .Nm set of commands first appeared in .Fx 9.0 . .Sh AUTHORS The .Nm set of commands was written by .An -nosplit .An Devin Teske Aq dteske@FreeBSD.org .
