    The yetris command, being primarily a game, typically does not accept command-line parameters for its core functionality. Interaction is performed through in-game key presses after the game starts. Some specific implementations might offer standard options like --help or --version, but these are not universally present across all yetris clones.

The yetris command is not a standard Linux system utility, but rather a common name for various independent, open-source implementations of the popular Tetris puzzle game, designed to be played directly within a terminal or console. These versions typically replicate the core gameplay of falling blocks (tetrominoes) that players must rotate and position to form complete horizontal lines, which then clear from the board. yetris projects are often developed using libraries like ncurses for text-based graphics, providing a retro gaming experience. Due to its nature as a game, it does not interact with the filesystem or manage system resources in the way typical Linux commands do. Installation usually involves compiling from source code or installing via specific distribution repositories that package such games. It offers a simple, engaging way to play Tetris directly on the command line without a graphical desktop environment.

The yetris command is not part of the standard GNU/Linux core utilities or a universally pre-installed package. Its availability depends on whether a specific distribution packages a yetris clone or if a user compiles it from source. Functionality and features can vary significantly between different open-source implementations that share the name. It is intended solely for interactive gameplay and offers no scripting capabilities or system administration functions.

Since yetris is an interactive game, its primary 'parameters' are typically keyboard inputs during gameplay. Common controls usually include:
Arrow Keys: Move left/right, soft drop (down).
Up Arrow Key or Spacebar: Rotate block.
'P' Key: Pause game.
'Q' Key: Quit game.
'R' Key: Restart game.
(Note: Specific key bindings may vary depending on the implementation and configuration.)

The concept of terminal-based Tetris clones like yetris emerged shortly after the original Tetris game gained widespread popularity. Developers often create their own versions as a programming exercise or for personal enjoyment, frequently utilizing text-based user interface libraries like ncurses or curses. As such, there isn't a single, definitive 'yetris' project with a linear development history, but rather numerous independent implementations that have been created and shared by various programmers over the years, each contributing to the legacy of command-line gaming.
