XREFRESH(1)

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 immediately 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.'' However, the various options can be used to indicate that a solid background (of any color) or the root window background 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(7).

-display display
    This argument allows you to specify the server and screen to refresh; see X(7).

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.

BUGS

It should have just one default type for the background.
