DESCRIPTION

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

OPTIONS

22       xmatrix accepts the following options:
23
24       --window
25               Draw on a newly-created window.  This is the default.
26
27       --root  Draw on the root window.
28
29       --window-id number
30               Draw on the specified window.
31
32       --install
33               Install a private colormap for the window.
34
35       --visual visual
36               Specify which visual to use.  Legal values are the  name  of  a
37               visual  class,  or the id number (decimal or hex) of a specific
38               visual.
39
40       --delay usecs
41               The delay between steps of the animation, in microseconds:  de‐
42               fault 10000.
43
44       --density percentage
45               The  approximate percentage of the screen that should be filled
46               with characters at any given time.  Default 75%.
47
48               When running in a window, typing + will  increase  the  density
49               and typing - will decrease it.  Typing 0 will momentarily drain
50               the screen.
51
52       --top | --bottom | --both
53               If --top is specified, the characters will only  drop  in  from
54               the  top  of  the  screen as sliding columns of characters.  If
55               --bottom is specified, then instead  of  sliding  columns,  the
56               characters  will  appear as columns that grow downwards and are
57               erased from above.  If --both is specified, then a  mixture  of
58               both styles will be used.  The default is --both.
59
60               When  running  in  a  window, typing [ will switch to top-mode,
61               typing ] will switch to bottom-mode, and typing \  will  switch
62               to both-mode.
63
64       --small | --large
65               These options specify the sizes of the characters.  The default
66               is --large.
67
68       --mode trace
69               Start off with a representation of a phone number being traced.
70               When  the number is finally found, display The Matrix as usual.
71               This is the default.
72
73       --phone number
74               The phone number to trace, if --trace is specified.
75
76       --mode crack
77               Start off by shutting down the power grid.
78
79       --mode binary
80               Instead of displaying Matrix glyphs, only display ones and  ze‐
81               ros.
82
83       --mode hexadecimal
84               Instead  of  displaying Matrix glyphs, display hexadecimal dig‐
85               its.
86
87       --mode dna
88               Instead of displaying Matrix glyphs, display genetic code (gua‐
89               nine, adenine, thymine, and cytosine.)
90
91       --mode ascii
92               Instead of displaying Matrix glyphs, display random ASCII char‐
93               acters.
94
95       --mode pipe
96               Instead of displaying random characters, display the output  of
97               a subprocess, as ASCII.
98
99       --program sh-command
100               The  command  to run to generate the text to display.  This op‐
101               tion may be any string acceptable to /bin/sh.  The program will
102               be  run at the end of a pty or pipe, and any characters that it
103               prints to stdout will be placed in the feeders for xmatrix.  If
104               the  program exits, it will be launched again after xmatrix has
105               processed all the text it produced.
106
107               For example:
108
109
110                    xmatrix -program 'echo Hello World'
111                    xmatrix -ascii -program 'ps -eo comm | rev'
112                    xmatrix -program 'od -txC -w6 /dev/random'
113                    xmatrix -program 'cat /dev/random'
114
