NAME
xrefresh - refresh all or part of an X screen

SYNOPSIS
xrefresh [-option ...]

DESCRIPTION
Xrefresh is a simple X program that causes all or part of
your screen to be repainted. This is useful when system
messages have messed up your screen. Xrefresh maps a window
on top of the desired area of the screen and then immedi-
ately unmaps it, causing refresh events to be sent to all
applications. By default, a window with no background is
used, causing all applications to repaint "smoothly." How-
ever, the various options can be used to indicate that a
solid background (of any color) or the root window back-
ground should be used instead.

ARGUMENTS
-white Use a white background. The screen just appears
to flash quickly, and then repaint.

-black Use a black background (in effect, turning off all
of the electron guns to the tube). This can be
somewhat disorienting as everything goes black for
a moment.

-solid color
Use a solid background of the specified color.
Try green.

-root Use the root window background.

-none This is the default. All of the windows simply
repaint.

-geometry WxH+X+Y
Specifies the portion of the screen to be
repainted; see X(1).

-display display
This argument allows you to specify the
server and screen to refresh; see X(1).

X DEFAULTS
The xrefresh program uses the routine XGetDefault(3X) to
read defaults, so its resource names are all capitalized.

Black, White, Solid, None, Root
Determines what sort of window background to use.

Geometry
Determines the area to refresh. Not very useful.

ENVIRONMENT
DISPLAY - To get default host and display number.
