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.
