gpiodetect: Lists GPIO chips and their line counts (e.g., gpiodetect).
gpioinfo: Shows GPIO line details (status, direction, labels) for a chip (e.g., gpioinfo gpiochip0).
gpioget: Reads GPIO line values (e.g., gpioget gpiochip0 17).
gpioset: Sets GPIO line values (e.g., gpioset gpiochip0 17=1).
gpiomon: Monitors GPIO lines for events (e.g., gpiomon gpiochip0 17).
gpiofind: Finds GPIO line by label (e.g., gpiofind led0).
gpiocfg: Configures GPIO properties like direction (e.g., gpiocfg gpiochip0 17 direction=output).
