cmatrix is a terminal-based program that simulates the iconic digital rain effect from the Matrix movie series. It displays scrolling green characters falling down the screen, creating a visual effect reminiscent of the film's representation of the Matrix's code.
The program is primarily used for aesthetic purposes, as a screensaver, or simply for entertainment. It can be customized with various colors, speeds, and display modes to suit user preferences.

-a

Enable asynchronous scrolling mode

Bold characters on

All bold characters (overrides -b)

Force the Linux $TERM type to be used

Linux mode (uses matrix console font)

Use old-style scrolling

Print usage and exit

No bold characters (overrides -b and -B)

Screensaver mode, exits on first keystroke

X window mode, exits on each keypress if run in a X terminal

Print version information and exit

Screen update delay (0-10, default 4)

Use specified color (green, red, blue, white, yellow, cyan, magenta, black)

Rainbow mode

Lambda mode (display lambda instead of characters)

Requires a terminal that supports ANSI escape codes and curses library. Heavy CPU usage may occur on slower systems at high speeds. The Linux console font mode (-l) only works on actual Linux consoles, not terminal emulators.

CMatrix was originally written by Chris Allegretta in 1999, inspired by the visual effects in the 1999 film "The Matrix." It was created as a fun terminal application for Unix-like systems and has become a popular way to add visual flair to terminal sessions. The project is open source and continues to receive updates from the community.
