XREFRESH(1)                          BSD                           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(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.

SEE ALSO
     X(1)

BUGS
     It should have just one default type for the background.
