The "xeyes" command is a graphical program in Unix-like operating systems that displays a pair of eyes which follow the movement of the cursor on the screen. When you execute the command "xeyes" in a terminal or command prompt, a window will open displaying two eyes, each consisting of a white sclera and a black pupil.
These eyes are animated and constantly track the movement of the mouse cursor. Wherever you move the cursor on the screen, the eyes will mimic the movement, as if they are watching it. It provides a fun and interactive way to visualize the tracking of cursor movements.
The "xeyes" program is a part of the X Window System, which is a windowing system for Unix-like operating systems that allows drawing and manipulating graphical user interfaces. It is often used as a demonstration or entertainment tool rather than having any practical use.
