|
|
.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.
|
|
.Pp
|
|
Before using any of the commands provided in
|
|
.Nm ,
|
|
it must be included
|
|
through the command:
|
|
.Pp
|
|
.Dl include version.4th
|
|
.Pp
|
|
This line is present in the default
|
|
.Pa /boot/menu.rc
|
|
file, so it is not needed (and should not be re-issued) in a normal setup.
|
|
.Pp
|
|
The commands provided by it are:
|
|
.Pp
|
|
.Bl -tag -width disable-module_module -compact -offset indent
|
|
.It 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
|
|
.Pp
|
|
The environment variables that effect its behavior are:
|
|
.Bl -tag -width bootfile -offset indent
|
|
.It 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.
|
|
.It Va loader_version_x
|
|
Sets the desired ending column position of
|
|
.Va loader_version .
|
|
Default is 80.
|
|
.It Va loader_version_y
|
|
Sets the desired ending row position of
|
|
.Va loader_version .
|
|
Default is 24.
|
|
.It Va loader_color
|
|
If set to
|
|
.Dq Li YES
|
|
(case-insensitive) or
|
|
.Dq Li 1 ,
|
|
causes the version to be printed in ANSI Cyan.
