The built-in toolbox tools in the Android system (under /system/bin) are too simple, and poorly supports some very useful Unix/Linux commands, such as find. In this case (to better use Unix utilities on Android), we can install BusyBox on Android OS in order to work with a variety of common Linux commands, tools.

BusyBox integrates hundreds of commonly used Unix utilities and tools into a single executable application for a variety of POSIX running environments such as Linux, Android, and FreeBSD. It includes simple but commonly-used tools such as ls, cat, and echo, as well as more powerful and complex tools such like grep, find, mount, and telnet.

BusyBox provides alternatives to most of the practical tools you can find in the GNU Core Utilities package of GNU software such as Fileutils, Shellutils, etc., thus building a fairly complete Linux running environment for any small or embedded operating system. At the same time, users can customize the root file system of Android with help of BusyBox, and it provides users with file backup, data recovery, background applications cleanup, as well as many other very useful functions.

Because of its small file size and powerful capabilities, some users like to call BusyBox the Swiss Army Knife among Linux tools with very high practicability. In short, BusyBox is like a big toolkit, which integrates almost all of the most commonly used tools and instructions in one place, also contains Android OS's own shell (which requires ROOT access permission). In fact, many applications that involve the operations of Android system core require BusyBox's support, such as our familiar data backup tool Titanium Backup.
