Description

This digital Short Cut delivered in Adobe PDF format for quick and easy access, is an introduction to BusyBox, widely regarded as "The Swiss Army Knife of Embedded Linux." After a brief introduction, we walk you through the BusyBox configuration utility. This is used to tailor BusyBox to your particular requirements. You will next learn about the requirements for cross-compiling the BusyBox package. Then we look at BusyBox operational issues, including how it is used in an embedded system. Next you will examine the BusyBox initialization sequence, and how this departs from more traditional Linux systems. You will also study a sample initialization script.

After reading the steps for installing BusyBox on a target system, you will learn about some of the BusyBox commands and their limitations.

This Short Cut is Chapter 11 from the book Embedded Linux Primer by Christopher Hallinan (0-13-167984-8) available September 2007. As such, it contains references to earlier and later chapters that are not included in this Short Cut. Apart from these references, the Short Cut is fully self-contained and is an excellent choice for embedded Linux developers interested in understanding how to use the BusyBox utility.
