This is the command xrefresh that can be run in the OnWorks free hosting provider using one of our multiple free online workstations such as Ubuntu Online, Fedora Online, Windows online emulator or MAC OS online emulator
xrefresh - refresh all or part of an X screen
xrefresh [-option ...]
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.
-white Use a white background. The screen just appears to flash quickly, and then
-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.
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.
Specifies the portion of the screen to be repainted; see X(7).
This argument allows you to specify the server and screen to refresh; see
The xrefresh program uses the routine XGetDefault(3) to read defaults, so its resource
names are all capitalized.
