ybacklight

ybacklight is a command line tool used in Linux systems to control the brightness of the screen. It provides a convenient way to adjust the backlight brightness of monitors. The utility is commonly used on laptops, desktops, and other devices with a display.

With ybacklight, users can increase or decrease the backlight brightness by specifying the desired value as a percentage. The tool communicates with the display's hardware through the kernel's sysfs interface, allowing for smooth and fine-grained adjustments.

ybacklight supports various command line options for different functionalities. For example, the "-get" option retrieves the current backlight brightness value, while the "-set" option sets the backlight brightness to a specific value.

This tool is often used in scripting and automation tasks, allowing users to programmatically adjust the display brightness based on various conditions or events.

It can be especially useful in environments where the default hardware controls, such as function keys, are not available or don't provide sufficient granularity in brightness adjustment.

ybacklight is highly customizable, allowing users to define their own key bindings or shortcuts to adjust the brightness quickly and efficiently. Additionally, it offers the possibility of mapping specific brightness levels to specific keyboard shortcuts.

Overall, ybacklight provides a flexible and efficient way to control the backlight brightness of displays in Linux systems, offering greater convenience and flexibility than the standard hardware controls.
