Please see the LICENSE file for copyright information. 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, /etc, and a kernel. 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, m68k, and MIPS. Supported libcs: glibc-2.0.x, glibc-2.1.x, glibc-2.2.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. ---------------- Shells: lash is the very smallest shell (adds just 10k) and it is quite usable as a command prompt, but it is not suitable for any but the most trivial scripting (such as an initrd that calls insmod a few times) since it does not understand Bourne shell grammer. It does handle pipes, redirects, and job control though. Adding in command editing makes it a very nice lightweight command prompt. hush is also quite small (just 18k) and it has very complete Bourne shell grammer. It handles if/then/else/fi just fine, but doesn't handle loops like for/do/done or case/esac and such. It also currently has a problem with job control. Using hush is not yet recommended. msh: The minix shell (adds just 30k) is quite complete and handles things like for/do/done, case/esac and all the things you expect a Bourne shell to do. It is not always pedantically correct about Bourne shell grammer (try running the shell testscript "tests/sh.testcases" on it and compare vs bash) but for most things it works quite well. It also uses only vfork, so it can be used on uClinux systems. This was only recently added, so there is still room to shrink it further... ash: This adds about 60k in the default configuration and is the most complete and most pedantically correct shell included with busybox. This shell was also recently added, and several people (mainly Vladimir and Erik) have been working on it. There are a number of configurable things at the top of ash.c as well, so check those out if you want to tweak things. ---------------- 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 bug report. Full instructions on how to report a bug are found at http://bugs.busybox.net/Reporting.html. For the impatient: To submit a bug, simply send an email describing the problem to submit@bugs.busybox.net. Bug reports should look something like this: To: submit@bugs.busybox.net From: diligent@testing.linux.org 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! -Diligent 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. ---------------- FTP: Source for the latest released version can always be downloaded from http://busybox.net/downloads/ ---------------- CVS: BusyBox now has its own publicly browsable CVS tree at: http://busybox.net/cgi-bin/cvsweb/busybox/ Anonymous CVS access is available. For instructions, check out: http://busybox.net/cvs_anon.html For those that are actively contributing there is even CVS write access: http://busybox.net/cvs_write.html ---------------- Please feed suggestions, bug reports, insults, and bribes back to: Erik Andersen
