shell – What adb KeyCode commands can I use to close all recent apps?

I use the following sequence of KeyCode commands to clear one and only one app in the recent apps menu, technically called the “application switcher dialog” in the Android KeyEvent documentation (

   adb shell input keyevent KEYCODE_APP_SWITCH
   adb shell input keyevent KEYCODE_DPAD_DOWN
   adb shell input keyevent KEYCODE_DEL

What I want is the ability to close multiple apps at once. Using the recent apps menu physically, I do this by tapping on the “Clear All” button.

Is there a way to simulate or initiate this action using ADB commands similar to the ones I listed above?

Please take careful note that I already know how to close or clear one app at a time. I am asking this because I’m looking for a quick way to close apps, besides repeated invocations of the above command sequence.
