BusyBox combines tiny versions of many common UNIX utilities into a single
|
|
small executable. It provides minimalist replacements for most of the utilities
|
|
you usually find in fileutils, shellutils, findutils, textutils, grep, gzip,
|
|
tar, etc. BusyBox provides a fairly complete POSIX environment for any small or
|
|
embedded system. 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 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 /dev, a shell, and a kernel. For
|
|
a really minimal system, you can even use the busybox shell (not Bourne
|
|
compatible, but very small and quite usable) and the busybox vi editor.
|
|
|
|
BusyBox was originally written to support the Debian Rescue/Install disks, but
|
|
it also makes an excellent environment for any small or embedded system.
|
|
|
|
As of version 0.20 there is now a version number. : ) Also as of version 0.20,
|
|
BusyBox is now modularized to easily allow you to build only the components you
|
|
need, thereby reducing binary size. To turn off unwanted BusyBox components,
|
|
simply edit the file "Config.h" and comment out the components you do not need
|
|
using C++ style (//) comments.
|
|
|
|
After the build is complete, a busybox.links file is generated. This is
|
|
used by 'make install' to create symlinks to the busybox binary for all
|
|
compiled in functions. By default, 'make install' will place the symlink
|
|
forest into `pwd`/_install unless you have defined the PREFIX environment
|
|
variable (i.e., 'make PREFIX=/tmp/foo install')
|
|
|
|
----------------
|
|
|
|
Supported architectures:
|
|
|
|
Busybox in general will build on any architecture supported by gcc. It has
|
|
a few specialized features added for __sparc__ and __alpha__. insmod
|
|
functionality is currently limited to x86, ARM, SH3/4, powerpc, and MIPS.
|
|
|
|
Supported libcs:
|
|
|
|
glibc-2.0.x, glibc-2.1.x, Linux-libc5, uClibc. People are looking at
|
|
newlib and diet-libc, but consider them unsupported, untested, or worse.
|
|
|
|
Supported kernels:
|
|
|
|
Full functionality requires Linux 2.0.x, 2.2.x, or 2.4.x. A large fraction
|
|
of the code should run on just about anything.

Subject: /bin/true doesn't work
|
|
|
|
Package: busybox
|
|
Version: 0.51
|
|
|
|
When I invoke '/bin/true' it doesn't work. I expected it to return
|
|
a "0" but it returned a "1" instead. Here is the transcript:
|
|
$ /bin/true ; echo $?
|
|
1
|
|
With GNU /bin/true, I get the following output:
|
|
$ /bin/true ; echo $?
|
|
0
|
|
I am using Debian 2.2r2, kernel version 2.2.18, and the latest
|
|
uClibc from CVS. Thanks for the wonderful program!

Note the careful description and use of examples showing not only what BusyBox
|
|
does, but also a counter example showing what an equivalent GNU app does. Bug
|
|
reports lacking such detail may take a _long_ time to be fixed... Thanks for
|
|
understanding.
