Why is Busybox still not recognized after installed properly? Busybox is installed in /system/bin successfully already, but I still can't call it as instructed in Using cut or sed in Android busybox:

C:\Users\Acer\Downloads\adb&gt;adb shell whence sed
/system/bin/sed

C:\Users\Acer\Downloads\adb&gt;adb shell whence busybox
/system/bin/busybox

C:\Users\Acer\Downloads\adb&gt;busybox
'busybox' is not recognized as an internal or external command,
operable program or batch file.
The mistake here is that you're trying to run Busybox by issuing busybox in your Windows terminal. This way, Windows searches for a program called busybox in its PATH, but doesn't find it, since it resides inside the /system/bin directory of your Android device.

To run any command residing on your Android device, you need to preface the actual command with adb shell, so adb shell busybox, in your case.
