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 GNU coreutils, util-linux, 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 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, /etc, and a Linux kernel.
|
|
BusyBox provides a fairly complete POSIX environment for any small or embedded
|
|
system.
|
|
|
|
BusyBox is extremely configurable. This allows you to include only the
|
|
components you need, thereby reducing binary size. Run 'make config' or
|
|
'make menuconfig' to select the functionality that you wish to enable.
|
|
|
|
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')
|
|
|
|
If you wish to install hard links, rather than symlinks, you can use
|
|
'make PREFIX=/tmp/foo install-hardlinks' instead.
|

|
----------------
|
|
|
|
Supported architectures:
|
|
|
|
BusyBox in general will build on any architecture supported by gcc.
|
|
Kernel module loading for 2.2 and 2.4 Linux kernels is currently
|
|
limited to ARM, CRIS, H8/300, x86, ia64, x86_64, m68k, MIPS, PowerPC,
|
|
S390, SH3/4/5, Sparc, v850e, and x86_64 for 2.4.x kernels. For 2.6.x
|
|
kernels, kernel module loading support should work on all architectures.
|
|
|
|
|
|
Supported C Libraries:
|
|
|
|
uClibc and glibc are supported. People have been looking at newlib and
|
|
dietlibc, but they are currently considered unsupported, untested, or
|
|
worse. Linux-libc5 is no longer supported -- you should probably use uClibc
|
|
instead if you want a small C library.
|
|
|
|
Supported kernels:
|
|
|
|
Full functionality requires Linux 2.2.x or better. A large fraction of the
|
|
code should run on just about anything. While the current code is fairly
|
|
Linux specific, it should be fairly easy to port the majority of the code
|
|
to support, say, FreeBSD or Solaris, or Mac OS X, or even Windows (if you
|
|
are into that sort of thing).

Getting help:
|
|
|
|
When you find you need help, you can check out the BusyBox mailing list
|
|
archives at http://busybox.net/lists/busybox/ or even join

the mailing list if you are interested.

Bugs:
|
|
|
|
If you find bugs, please submit a detailed bug report to the BusyBox mailing
|
|
list at busybox@mail.busybox.net. A well-written bug report should include a
|
|
transcript of a shell session that demonstrates the bad behavior and enables
|
|
anyone else to duplicate the bug on their own machine. The following is such
|
|
an example:
|
|
|
|
To: busybox@mail.busybox.net

|
From: diligent@testing.linux.org

|
Subject: /bin/date doesn't work
|
|
|
|
Package: BusyBox
|
|
Version: 1.00
|
|
|
|
When I execute BusyBox 'date' it produces unexpected results.
|
|
With GNU date I get the following output:
|
|
|
|
$ date
|
|
Fri Oct 8 14:19:41 MDT 2004
|
|
|
|
But when I use BusyBox date I get this instead:
|
|
|
|
$ date
|
|
illegal instruction
|
|
|
|
I am using Debian unstable, kernel version 2.4.25-vrs2 on a Netwinder,
|
|
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 never be fixed... Thanks for understanding.
