The xkbbell command allows users to configure the audible bell (beep) of the X keyboard. It provides options to control the bell's volume, pitch, and duration. This utility is primarily useful in environments where audible feedback is desired for certain keyboard events, such as errors or warnings. xkbbell can be used to customize the bell sound to be more pleasant or less disruptive, or to disable the bell entirely.

The command interacts with the X Keyboard Extension (XKB) to modify bell-related settings. It is often used in conjunction with other X configuration tools to create a personalized desktop environment. This simple tool contributes to the overall accessibility and usability of the X Window System. While modern graphical environments often provide their own bell customization options, xkbbell offers a command-line alternative that can be useful for scripting and remote management.

xkbbell -off: Disables the keyboard bell.
xkbbell -volume 50 -pitch 1000 -duration 200: Sets the volume to 50%, pitch to 1000Hz, and duration to 200ms.
xkbbell -default: Resets the bell settings to default.
