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).

       -version  This argument prints the program version and exits.

X DEFAULTS

       The  xrefresh  program  uses  the  routine XGetDefault(3) 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.
