This App Sets Up a Linux Shell Environment This app has allowed me to discover much about the inner workings of Android devices. I have the advantage that I have Linux experience. Not all devices are made alike. Success will depend on the device. This app is best had with Hacker's keyboard. Linux commands are created by making a symbolic (soft) links to busybox or toolbox. This however requires ROOT. The filesystem on the user's """"""""sdcard"""""""" does not support symbolic links. Without root the user is limited to the Linux commands that the manfacturer put in. Use the cp command to copy some files from internal memory to the sdcard. Use df to find block devices (drives) . Type the word """"""""busybox"""""""" and read how Android uses one file to implement numerous commands. On many devices """"""""toolbox""""""""  is used in place of busybox.This app may need work on the higher versions of Android.""
