Questions tagged [busybox]

BusyBox is a single executable implementation of the common UNIX utilities that has been optimized for minimal size.

BusyBox: The Swiss Army Knife of Embedded Linux

BusyBox combines limited versions of the UNIX utilities commonly found in the GNU fileutiles, shellutils, etc. packages into one executable that has been optimized for systems with limited resources (such as embedded systems). The BusyBox tools are not as full featured as their GNU counterparts but they provide the bare essentials and necessary functionality.

BusyBox is also very modular so the developer can only include the features and commands that they need.
