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

14 The xmatrix program draws the 2D "digital rain" effect, as seen on the
15 computer monitors in the Wachowski brothers' film, "The Matrix".
16 Also see glmatrix(6x) for a 3D rendering of the similar effect that
18 appeared in the title sequence of the movie.
19
21 xmatrix accepts the following options:
22 -window Draw on a newly-created window. This is the default.
24 -root Draw on the root window.
26 -install
28 Install a private colormap for the window.
29 -visual visual
31 Specify which visual to use. Legal values are the name of a
32 visual class, or the id number (decimal or hex) of a specific
33 visual.
34 -delay usecs
36 The delay between steps of the animation, in microseconds:
37 default 10000.
38 -density percentage
40 The approximate percentage of the screen that should be filled
41 with characters at any given time. Default 75%.
42 When running in a window, typing + will increase the density
44 and typing - will decrease it. Typing 0 will momentarily drain
45 the screen.
46 -top | -bottom | -both
48 If -top is specified, the characters will only drop in from the
49 top of the screen as sliding columns of characters. If -bottom
50 is specified, then instead of sliding columns, the characters
51 will appear as columns that grow downwards and are erased from
52 above. If -both is specified, then a mixture of both styles
53 will be used. The default is -both.
54 When running in a window, typing [ will switch to top-mode,
56 typing ] will switch to bottom-mode, and typing \ will switch
57 to both-mode.
58 -small | -large
60 These options specify the sizes of the characters. The default
61 is -large.
62 -mode trace
64 Start off with a representation of a phone number being traced.
65 When the number is finally found, display The Matrix as usual.
66 This is the default.
67 -phone number
69 The phone number to trace, if -trace is specified.
70 -mode crack
72 Start off by shutting down the power grid.
73 -mode binary
75 Instead of displaying Matrix glyphs, only display ones and
76 zeros.
77 -mode hexadecimal
79 Instead of displaying Matrix glyphs, display hexadecimal dig‐
80 its.
81 -mode dna
83 Instead of displaying Matrix glyphs, display genetic code (gua‐
84 nine, adenine, thymine, and cytosine.)
85 -mode ascii
87 Instead of displaying Matrix glyphs, display random ASCII char‐
88 acters.
89 -mode pipe
91 Instead of displaying random characters, display the output of
92 a subprocess, as ASCII.
93 -program sh-command
95 The command to run to generate the text to display. This
96 option may be any string acceptable to /bin/sh. The program
97 will be run at the end of a pty or pipe, and any characters
98 that it prints to stdout will be placed in the feeders for xma‐
99 trix. If the program exits, it will be launched again after
100 xmatrix has processed all the text it produced.
101 For example:
103 xmatrix -program 'echo Hello World'
104 xmatrix -ascii -program 'ps -eo comm | rev'
105 xmatrix -program 'od -txC -w6 /dev/random'
106 xmatrix -program 'cat /dev/random'
107
109 DISPLAY to get the default host and display number.
110 XENVIRONMENT
112 to get the name of a resource file that overrides the global
113 resources stored in the RESOURCE_MANAGER property.
