About BusyBox
BusyBox for Windows (busybox-w32) is a port of BusyBox to the Windows WIN32 API. It provides many common Unix tools in a single self-contained native executable, implementing well over a hundred Unix-style commands including an ash-based shell, awk, sed, vi, find and grep.
Commands can be run individually from a Command Prompt window or through the BusyBox shell, with --install and --uninstall options to manage links to applets. It brings only a subset of BusyBox functionality to Windows and the page notes it may not suit users who need the full power of bash or other GNU utilities.
