SYNOPSIS

9       xmatrix  [-display  host:display.screen]  [-window]  [-root] [-install]

DESCRIPTION

14       The  xmatrix program draws the 2D "digital rain" effect, as seen on the
15       computer monitors in the 1999 film, "The Matrix".
16
17       Also see glmatrix(6x) for a 3D rendering of the similar effect that ap‐
18       peared in the title sequence of the movie.
19

OPTIONS

21       xmatrix accepts the following options:
22
23       -window Draw on a newly-created window.  This is the default.
24
25       -root   Draw on the root window.
26
27       -install
28               Install a private colormap for the window.
29
30       -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
35       -delay usecs
36               The  delay between steps of the animation, in microseconds: de‐
37               fault 10000.
38
39       -density percentage
40               The approximate percentage of the screen that should be  filled
41               with characters at any given time.  Default 75%.
42
43               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
47       -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
55               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
59       -small | -large
60               These options specify the sizes of the characters.  The default
61               is -large.
62
63       -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
68       -phone number
69               The phone number to trace, if -trace is specified.
70
71       -mode crack
72               Start off by shutting down the power grid.
73
74       -mode binary
75               Instead  of displaying Matrix glyphs, only display ones and ze‐
76               ros.
77
78       -mode hexadecimal
79               Instead of displaying Matrix glyphs, display  hexadecimal  dig‐
80               its.
81
82       -mode dna
83               Instead of displaying Matrix glyphs, display genetic code (gua‐
84               nine, adenine, thymine, and cytosine.)
85
86       -mode ascii
87               Instead of displaying Matrix glyphs, display random ASCII char‐
88               acters.
89
90       -mode pipe
91               Instead  of displaying random characters, display the output of
92               a subprocess, as ASCII.
93
94       -program sh-command
95               The command to run to generate the text to display.   This  op‐
96               tion may be any string acceptable to /bin/sh.  The program will
97               be run at the end of a pty or pipe, and any characters that  it
98               prints  to stdout will be placed in the feeders for xmatrix. If
99               the program exits, it will be launched again after xmatrix  has
100               processed all the text it produced.
101
102               For example:
103
104
105                    xmatrix -program 'echo Hello World'
106                    xmatrix -ascii -program 'ps -eo comm | rev'
107                    xmatrix -program 'od -txC -w6 /dev/random'
108                    xmatrix -program 'cat /dev/random'
