accepts the following options:
- Draw on a newly-created window. This is the default.
- Draw on the root window.
- 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:
- -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
- -top | -bottom |
- 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
- -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
- -mode crack
- Start off by shutting down the power grid.
- -mode binary
- Instead of displaying Matrix glyphs, only display ones and
- -mode hexadecimal
- Instead of displaying Matrix glyphs, display hexadecimal
- -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
- -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
xmatrix -program 'echo Hello World'
xmatrix -ascii -program 'ps -eo comm | rev'
xmatrix -program 'od -txC -w6 /dev/random'
xmatrix -program 'cat /dev/random'

- to get the name of a resource file that overrides the
global resources stored in the RESOURCE_MANAGER property.
