How to get shell with busybox on android? I installed busybox free on my android device. I have super user and stuff. When I click on the busybox widget, it gets me to the configuration utility where I can install / uninstall. It is installed. How can I execute the busybox binary now?
BusyBox: The Swiss Army Knife of Embedded Linux


  BusyBox combines tiny versions of many common UNIX utilities into a
  single small executable. It provides replacements for most of the
  utilities you usually find in GNU fileutils, shellutils, etc. The
  utilities in BusyBox generally have fewer options than their
  full-featured GNU cousins; however, the options that are included
  provide the expected functionality and behave very much like their GNU
  counterparts. BusyBox provides a fairly complete environment for any
  small or embedded system.
  
  BusyBox has been written with size-optimization and limited resources
  in mind. It is also extremely modular so you can easily include or
  exclude commands (or features) at compile time. This makes it easy
  to customize your embedded systems. To create a working system, just
  add some device nodes in /dev, a few configuration files in
  /etc, and a Linux kernel.


also, as GiantTree said, 

you need to download the (Terminal Emulator - Google play).

and after install (and also install the binary and get root permission), you can use the terminal serve as more Permissions and it support Busy Box Binaries.
This is the Syntax of use this project :
