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

NAME

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

SYNOPSIS

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

DESCRIPTION

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

OPTIONS

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.

ENVIRONMENT

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.
