xmatrix(6) XScreenSaver manual xmatrix(6) NAME xmatrix - simulates the computer displays from the movie SYNOPSIS xmatrix [--display host:display.screen] [--window] [--root] [--window-id number][--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 com- puter monitors in the 1999 film, "The Matrix". Also see glmatrix(6) 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. --window-id number Draw on the specified 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 ap- pear 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 charac- ters. --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 re- sources stored in the RESOURCE_MANAGER property. XSCREENSAVER_WINDOW The window ID to use with --root.
