We've discussed about the Android / Linux Command in separate article. Here, we want to talk about what we can use and where to find the useful commands in Android device. Connect your Android device and launch a command line window in advance. Then you can try to use all these commands by executing command adb shell command_name.

The following commands can be found in the folder "/system/bin/ on Nexus 7.
