The worms command is a simple, terminal-based program that displays moving, segmented lines resembling worms crawling across the screen. It's primarily a novelty program, used for entertainment or to add a quirky visual effect to a terminal session. The worms randomly change direction, providing a dynamic and unpredictable animation. The command offers a limited number of options to control the number of worms and the speed of their movement. It's a lightweight program, not designed for serious or practical tasks, but rather for adding some visual amusement to a command-line environment.
The user must terminate the program with Ctrl+C.

The worms program continues running until manually terminated with Ctrl+C.
