NAME

       xmatrix - simulates the computer displays from the movie

SYNOPSIS

       xmatrix [-display host:display.screen] [-window] [-root] [-install] [-visual visual] [-delay usecs] [-density percentage] [-top | -bottom |
       -both] [-small | -large] [-trace] [-mode mode] [-phone number] [-fps]

DESCRIPTION

       The xmatrix program draws the 2D "digital rain" effect, as seen on the computer monitors in the Wachowski brothers' film, "The Matrix".

       Also see glmatrix(6x) for a 3D rendering of the similar effect that appeared in the title sequence of the movie.

OPTIONS

       xmatrix 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.

       -delay usecs
	       The delay between steps of the animation, in microseconds: default 10000.

       -density percentage
	       The approximate percentage of the screen that should be filled with characters at any given time.  Default 75%.

	       When running in a window, typing + will increase the density and typing - will decrease it.  Typing 0 will  momentarily	drain  the
	       screen.

       -top | -bottom | -both
	       If  -top is specified, the characters will only drop in from the top of the screen as sliding columns of characters.  If -bottom is
	       specified, then instead of sliding columns, the characters will appear as columns that grow downwards and are  erased  from  above.
	       If -both is specified, then a mixture of both styles will be used.  The default is -both.

	       When  running in a window, typing [ will switch to top-mode, typing ] will switch to bottom-mode, and typing  will switch to both-
	       mode.

       -small | -large
	       These options specify the sizes of the characters.  The default is -large.

       -mode trace
	       Start off with a representation of a phone number being traced.	When the number is finally found, display  The	Matrix	as  usual.
	       This is the default.

       -phone number
	       The phone number to trace, if -trace is specified.

       -mode crack
	       Start off by shutting down the power grid.

       -mode binary
	       Instead of displaying Matrix glyphs, only display ones and zeros.

       -mode hexadecimal
	       Instead of displaying Matrix glyphs, display hexadecimal digits.

       -mode dna
	       Instead of displaying Matrix glyphs, display genetic code (guanine, adenine, thymine, and cytosine.)

       -mode ascii
	       Instead of displaying Matrix glyphs, display random ASCII characters.

       -mode pipe
	       Instead of displaying random characters, display the output of a subprocess, as ASCII.

       -program sh-command
	       The  command to run to generate the text to display.  This option may be any string acceptable to /bin/sh.  The program will be run
	       at the end of a pty or pipe, and any characters that it prints to stdout will be placed in the feeders for xmatrix. If the  program
	       exits, it will be launched again after xmatrix has processed all the text it produced.

	       For example:
	       xmatrix -program 'echo Hello World'
	       xmatrix -ascii -program 'ps -eo comm | rev'
	       xmatrix -program 'od -txC -w6 /dev/random'
	       xmatrix -program 'cat /dev/random'

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.
