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 emdedded 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 a kernel, a shell (such as ash),
|
|
and an editor (such as elvis-tiny or ae).
|
|
<p>
|
|
|
|
BusyBox is now maintained by
|
|
<a href="http://www.xmission.com/~andersen/erik/erik.html">

<p> <li> <b>19 April 2000 -- syslogd bugfix</b>
|
|
<br>
|
|
Turns out that there was still a bug in busybox syslogd.
|
|
For example, with the following test app:
|
|
<pre>
|
|
#include <syslog.h>
|
|
|
|
int do_log(char* msg, int delay)
|
|
{
|
|
openlog("testlog", LOG_PID, LOG_DAEMON);
|
|
while(1) {
|
|
syslog(LOG_ERR, "%s: testing one, two, three\n", msg);
|
|
sleep(delay);
|
|
}
|
|
closelog();
|
|
return(0);
|
|
};
|
|
|
|
int main(void)
|
|
{
|
|
if (fork()==0)
|
|
do_log("A", 2);
|
|
do_log("B", 3);
|
|
}
|
|
</pre>
|
|
it should be logging stuff from both "A" and "B". As released in 0.43 only stuff
|
|
from "A" would have been logged. This means that if init tries to log something
|
|
while say ppp has the syslog open, init would block (which is bad, bad, bad).
|
|
<p>
|
|
Karl M. Hegbloom has created a
|
|
<a href="ftp://ftp.lineo.com/pub/busybox/busybox-0.43-syslog_patch">fix for the problem</a>.
|
|
Thanks Karl!
|
|
|
|
|
|
<p> <li> <b>18 April 2000 -- BusyBox 0.43 released (finally!)</b>
|
|
<br>
|
|
I have finally gotten everything into a state where I feel pretty
|
|
good about things. This is definitely the most stable, solid release
|
|
so far. A lot of bugs have been fixed, and the following new apps
|
|
have been added: sh, basename, dirname, killall, uptime,
|
|
freeramdisk, tr, echo, test, and usleep. Tar has been completely
|
|
rewritten from scratch. Bss size has also been greatly reduced.
|
|
More details are available in the
|
|
<a href="ftp://ftp.lineo.com/pub/busybox/Changelog">changelog</a>.
|
|
Oh, and as a special bonus, I wrote some fairly comprehensive
|
|
<em>documentation</em>, complete with examples and full usage information.
|
|
|
|
<p>
|
|
Many thanks go out to the fine people that have helped by submitting patches
|
|
and bug reports; particularly instrumental in helping for this release were
|
|
Karl Hegbloom, Pavel Roskin, Friedrich Vedder, Emanuele Caratti,
|
|
Bob Tinsley, Nicolas Pitre, Avery Pennarun, Arne Bernin, John Beppu, and Jim Gleason.
|
|
There were others so if I somehow forgot to mention you, I'm very sorry.
|
|
<p>
|
|
|
|
You can grab BusyBox 0.43 tarballs <a href="ftp://ftp.lineo.com/pub/busybox/">here</a>.
|
|
|
|
<p> <li> <b>9 April 2000 -- BusyBox 0.43 pre release</b>
|
|
<br>
|
|
Unfortunately, I have not yet finished all the things I want to
|
|
do for BusyBox 0.43, so I am posting this pre-release for people
|
|
to poke at. This contains my complete rewrite of tar, which now weighs in at
|
|
5k (7k with all options turned on) and works for reading and writing
|
|
tarballs (which it does correctly for everything I have been able to throw
|
|
at it). Tar also (optionally) supports the "--exclude" option (mainly because
|
|
the Linux Router Project folks asked for it). This also has a pre-release
|
|
of the micro shell I have been writing. This pre-release should be stable
|
|
enough for production use -- it just isn't a release since I have some structural
|
|
changes I still want to make.
|
|
<p>
|
|
The pre-release can be found <a href="ftp://ftp.lineo.com/pub/busybox/">here</a>.
|
|
Please let me know ASAP if you find <em>any</em> bugs.
|
|
|
|
<p> <li> <b>28 March 2000 -- Andersen Baby Boy release</b>
|
|
<br>
|
|
I am pleased to announce that on Tuesday March 28th at 5:48pm, weighing in at 7
|
|
lbs. 12 oz, Micah Erik Andersen was born at LDS Hospital here in Salt Lake City.
|
|
He was born in the emergency room less then 5 minutes after we arrived -- and
|
|
it was such a relief that we even made it to the hospital at all. Despite the
|
|
fact that I was driving at an amazingly unlawful speed and honking at everybody
|
|
and thinking decidely unkind thoughts about the people in our way, my wife
|
|
(inconsiderate of my feelings and complete lack of medical training) was lying
|
|
down in the back seat saying things like "I think I need to start pushing now"
|
|
(which she then proceeded to do despite my best encouraging statements to the
|
|
contrary).
|
|
<p>
|
|
Anyway, I'm glad to note that despite the much-faster-than-we-were-expecting
|
|
labor, both Shaunalei and our new baby boy are doing wonderfuly.
|
|
<p>
|
|
So now that I am done with my excuse for the slow release cycle...
|
|
Progress on the next release of BusyBox has been slow but steady. I expect
|
|
to have a release sometime during the first week of April. This release will
|
|
include a number of important changes, including the addition of a shell, a
|
|
re-write of tar (to accomodate the Linux Router Project), and syslogd can now
|
|
accept multiple concurrent connections, fixing lots of unexpected blocking
|
|
problems.
|
|
|
|
|
|
<p> <li> <b>11 February 2000 -- BusyBox 0.42 released</b>
|
|
<br>
|
|
|
|
This is the most solid BusyBox release so far. Many, many
|
|
bugs have been fixed. See the
|
|
<a href="ftp://ftp.lineo.com/pub/busybox/Changelog">changelog</a> for details.
|
|
|
|
Of particular interest, init will now cleanly unmount
|
|
filesystems on reboot, cp and mv have been rewritten and
|
|
behave much better, and mount and umount no longer leak
|
|
loop devices. Many thanks go out to Randolph Chung,
|
|
Karl M. Hegbloom, Taketoshi Sano, and Pavel Roskin for
|
|
their hard work on this release of BusyBox. Please pound
|
|
on it and let me know if you find any bugs.
|
|
|
|
<p> <li> <b>19 January 2000 -- BusyBox 0.41 released</b>
|
|
<br>
|
|
|
|
This release includes bugfixes to cp, mv, logger, true, false,
|
|
mkdir, syslogd, and init. New apps include wc, hostid,
|
|
logname, tty, whoami, and yes. New features include loop device
|
|
support in mount and umount, and better TERM handling by init.
|
|
The changelog can be found <a href="ftp://ftp.lineo.com/pub/busybox/Changelog">here</a>.
|
|
|
|
<p> <li> <b>7 January 2000 -- BusyBox 0.40 released</b>
|
|
<br>
|
|
|
|
This release includes bugfixes to init (now includes inittab support),
|
|
syslogd, head, logger, du, grep, cp, mv, sed, dmesg, ls, kill, gunzip, and mknod.
|
|
New apps include sort, uniq, lsmod, rmmod, fbset, and loadacm.
|
|
In particular, this release fixes an important bug in tar which
|
|
in some cases produced serious security problems.

<li><a href="http://www.debian.org/Packages/unstable/shells/ash.html">ash</a>
|

is a very small Bourne shell. If you need a shell for your embedded systems, this is it.
|
|
<p>
|
|
|
|
<li><a href="http://www.debian.org/Packages/unstable/base/ae.html">ae</a>
|
|
is a tiny full-screen text editor with both modal (vi-like) and modeless
|
|
(emacs-like) modes, determined by an ae.rc config file. It makes a nice editor
|
|
if people that don't know "vi" will need to work on your embedded system.

|
<p>
|
|
|
|
<li> <a href="http://www.debian.org/Packages/unstable/base/elvis-tiny.html">elvis-tiny</a>
|
|
is based on a 1991 Minix version of the elvis "vi" clone. It behaves as one would
|

expect a minamalist vi to behave, and is very small.
|

<p>
|
|

A small GPLed pico clone that makes a nice editor for people that don't know "vi".

|
|
|

<li><a href="http://www.debian.org/Packages/unstable/net/iproute.html">iproute</a>
|
|
Much more flexible replacement for ifconfig, route, etc. It is quite small, and for
|
|
most networking applications, it is all you need. It also provides support for extremely
|
|
advanced networking and provides Quality of Service(QoS) support, but most people will
|
|
just need to use the "ip" command and will not even need to install the rest.
|
|
<p>
|
|
|
|
<li><a href="http://www.debian.org/Packages/unstable/net/pump.html">Pump</a>
|
|
This is the DHCP/BOOTP client written by RedHat. When compiled properly, it
|

gives you dhcp client support for about 35k.
|
|
<p>
|
|
|
|
<li><a href="http://www.pcug.org.au/~dbell/">sash</a>
|
|
The Stand Alone SHell. This is a small shell (not Bourne shell compatable)
|
|
that is similar to busybox in that it provides a number of common utilities as built-ins.
|
|
<p>
|
|
|
|
<li><a href="http://sourceware.cygnus.com/newlib/">NewLib</a>
|

This is a small C library intended for use on embedded systems. If you are finding

GNU libc is a bit too big for your applications, try NewLib and it may help.
|
|
<p>
|
|
|
|
<li><a href="http://linuxassembly.org/asmutils.html">asmutils</a>
|
|
asmutils is similar to BusyBox in that it provides a number of common application
|
|
for embedded systems that are very tiny. In fact, they are a _lot_ smaller than the
|
|
equivalent apps in busybox -- but the price you pay for the size is reduced portability
|
|
(x86 only) and interfaces that are tied directly to a perticular kernel (no libc involved).
|
|
<p>
|
|
|
|
<li><a href="http://tinylogin.lineo.com/">TinyLogin</a>
|
