XREFRESH(1)						      General Commands Manual						       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.

SEE ALSO

       X(7)

BUGS

       It should have just one default type for the background.
