memscroller — scrolls a dump of its own RAM across the screen


memscroller [-display host:display.screen] [-window] [-root] [-mono] [-install] [-visual visual] [-font font] [-delay int] [-mono | -color] [-ram | -random | -filename file] [-fps]


The memscroller program scrolls a dump of its own process memory across the screen in three windows at three different rates.


memscroller accepts the following options:

Draw on a newly-created window. This is the default.
Draw on the root window.
Install a private colormap for the window.
-visual visual
Specify which visual to use. Legal values are the name of a visual class, or the id number (decimal or hex) of a specific visual.
Render each three bytes of memory as R, G, B. This is the default.
Render each byte of memory in shades of green.
Read from the process's address space. This is the default.
Instead of reading from memory, generate random numbers.
-filename file
Instead of reading from memory, read from the given file until EOF, then re-open it. If you have permission, /dev/mem is an interesting choice here. (Note that /dev/null won't ever display anything, because it returns EOF without ever returning any data.)
-delay microseconds
How much of a delay should be introduced between steps of the animation. Default 10000.
Display the current frame rate and CPU load.


to get the default host and display number.
to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
