The command "dark-mode on" is typically used to enable a dark mode or dark theme on a device or application. Dark mode is a user interface option that replaces bright, light-colored elements with dark ones. Enabling dark mode can be beneficial as it reduces eye strain, improves readability in low-light conditions, and conserves battery life on devices with OLED or AMOLED screens.

When you enter the command "dark-mode on," it instructs the system or application to activate its dark mode feature, converting the interface from a light color scheme to a dark color scheme. The specific implementation and appearance of dark mode may vary depending on the device or application you are using.
