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:
-window
Draw on a newly-created window. This is the default.
-root
Draw on the root window.
-install
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.
-color
Render each three bytes of memory as R, G, B. This is the default.
-mono
Render each byte of memory in shades of green.
-ram
Read from the process's address space. This is the default.
-random
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.
-fps
Display the current frame rate and CPU load.
DISPLAY
to get the default host and display number.
XENVIRONMENT
to get the name of a resource file that overrides the global resources stored in the RESOURCE_MANAGER property.
