       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.
