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.
|
|
<p>
|
|
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 kernel, and a shell.
|
|
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.
|
|
<p>
|
|
|
|
BusyBox is now maintained by
|
|
<a href="http://codepoet.org/andersen/erik/erik.html">

|
Erik Andersen</a>, and its ongoing development is being sponsored by

<li> <b>7 July 2001 -- BusyBox 0.52 released</b>
|
|
<br>
|
|
|
|
I am very pleased to announce the immediate availability of
|
|
BusyBox 0.52 (the "new-and-improved rock-solid release"). This
|
|
release is the result of <em>many</em> hours of work and has tons
|
|
of bugfixes, optimizations, and cleanups. This release adds
|
|
several new applets, including several new shells (such as hust, msh,
|
|
and ash).
|
|
|
|
<p>
|
|
The
|
|
<a href="ftp://oss.lineo.com/busybox/Changelog">changelog</a> covers
|
|
some of the more obvious details, but there are many many things that
|
|
are not mentioned, but have been improved in subtle ways. As usual,
|
|
BusyBox 0.52 can be downloaded from
|
|
<a href="ftp://oss.lineo.com/busybox">ftp://oss.lineo.com/busybox</a>.
|
|
<p>Have Fun!
|
|
<p>

|
<li> <b>10 April 2001 - Graph of Busybox Growth </b>
|
|
<br>
|
|
The illustrious Larry Doolittle has made a PostScript chart of the growth
|
|
of the Busybox tarball size over time. It is available for downloading /
|
|
viewing <a href= "busybox-growth.ps"> right here</a>.
|
|
|
|
<p> (Note that while the number of applets in Busybox has increased, you
|
|
can still configure Busybox to be as small as you want by selectively
|
|
turning off whichever applets you don't need.)
|
|
<p>
|
|
|
|
<li> <b>10 April 2001 -- BusyBox 0.51 released</b>
|
|
<br>
|
|
|
|
BusyBox 0.51 (the "rock-solid release") is now out there. This
|
|
release adds only 2 new applets: env and vi. The vi applet,
|
|
contributed by Sterling Huxley, is very functional, and is only
|
|
22k. This release fixes 3 critical bugs in the 0.50 release.
|
|
There were 2 potential segfaults in lash (the busybox shell) in
|
|
the 0.50 release which are now fixed. Another critical bug in
|
|
0.50 which is now fixed: syslogd from 0.50 could potentially
|
|
deadlock the init process and thereby break your entire system.
|
|
<p>
|
|
|
|
There are a number of improvements in this release as well. For
|
|
one thing, the wget applet is greatly improved. Dmitry Zakharov
|
|
added FTP support, and Laurence Anderson make wget fully RFC
|
|
compliant for HTTP 1.1. The mechanism for including utility
|
|
functions in previous releases was clumsy and error prone. Now
|
|
all utility functions are part of a new libbb library, which makes
|
|
maintaining utility functions much simpler. And BusyBox now
|
|
compiles on itanium systems (thanks to the Debian itanium porters
|
|
for letting me use their system!).
|
|
<p>
|
|
You can read the
|
|
<a href="ftp://oss.lineo.com/busybox/Changelog">changelog</a> for
|
|
complete details. BusyBox 0.51 can be downloaded from
|
|

<li> <b>Busybox Boot-Floppy Image</b>
|
|
|
|
<p>Because you asked for it, we have made available a <a href=
|
|
"ftp://opensource.lineo.com/busybox/busybox.floppy.img"> Busybox boot floppy
|
|
image</a>. Here's how you use it:
|
|
|
|
<ol>
|
|
|
|
<li> <a href= "ftp://opensource.lineo.com/busybox/busybox.floppy.img">
|
|
Download the image</a>
|
|
|
|
<li> dd it onto a floppy like so: <tt> dd if=busybox.floppy.img
|
|
of=/dev/fd0 ; sync </tt>
|
|
|
|
<li> Pop it in a machine and boot up.
|
|
|
|
</ol>
|
|
|
|
<p> If you want to look at the contents of the initrd image, do this:
|
|
|
|
<pre>
|
|
mount ./busybox.floppy.img /mnt -o loop -t msdos
|
|
cp /mnt/initrd.gz /tmp
|
|
umount /mnt
|
|
gunzip /tmp/initrd.gz
|
|
mount /tmp/initrd /mnt -o loop -t minix
