53<h1><a name="description">DESCRIPTION</a></h1>
54<p>BusyBox combines tiny versions of many common UNIX utilities into a single
55small executable. It provides minimalist replacements for most of the utilities
56you usually find in GNU coreutils, util-linux, etc. The utilities in BusyBox
57generally have fewer options than their full-featured GNU cousins; however, the
58options that are included provide the expected functionality and behave very
59much like their GNU counterparts.</p>
60<p>BusyBox has been written with size-optimization and limited resources in mind.
61It is also extremely modular so you can easily include or exclude commands (or
62features) at compile time. This makes it easy to customize your embedded
63systems. To create a working system, just add /dev, /etc, and a Linux kernel.
64BusyBox provides a fairly complete POSIX environment for any small or embedded
65system.</p>
66<p>BusyBox is extremely configurable.  This allows you to include only the
67components you need, thereby reducing binary size. Run 'make config' or 'make
68menuconfig' to select the functionality that you wish to enable.  Then run
69'make' to compile BusyBox using your configuration.</p>
70<p>After the compile has finished, you should use 'make install' to install
71BusyBox. This will install the 'bin/busybox' binary, in the target directory
72specified by CONFIG_PREFIX. CONFIG_PREFIX can be set when configuring BusyBox,
73or you can specify an alternative location at install time (i.e., with a
74command line like 'make CONFIG_PREFIX=/tmp/foo install'). If you enabled
75any applet installation scheme (either as symlinks or hardlinks), these will
76also be installed in the location pointed to by CONFIG_PREFIX.</p>
77<p>

80<h1><a name="usage">USAGE</a></h1>
81<p>BusyBox is a multi-call binary.  A multi-call binary is an executable program
82that performs the same job as more than one utility program.  That means there
83is just a single BusyBox binary, but that single binary acts like a large
84number of utilities.  This allows BusyBox to be smaller since all the built-in
85utility programs (we call them applets) can share code for many common
86operations.</p>
87<p>You can also invoke BusyBox by issuing a command as an argument on the
88command line.  For example, entering</p>
89<pre>
90        /bin/busybox ls</pre>
91<p>will also cause BusyBox to behave as 'ls'.</p>
92<p>Of course, adding '/bin/busybox' into every command would be painful.  So most
93people will invoke BusyBox using links to the BusyBox binary.</p>
94<p>For example, entering</p>
95<pre>
96        ln -s /bin/busybox ls
97        ./ls</pre>
98<p>will cause BusyBox to behave as 'ls' (if the 'ls' command has been compiled
99into BusyBox).  Generally speaking, you should never need to make all these
100links yourself, as the BusyBox build system will do this for you when you run
101the 'make install' command.</p>
102<p>If you invoke BusyBox with no arguments, it will provide you with a list of the
103applets that have been compiled into your BusyBox binary.</p>
104<p>
105</p>
106<hr />
107<h1><a name="common_options">COMMON OPTIONS</a></h1>
108<p>Most BusyBox applets support the <strong>--help</strong> argument to provide a terse runtime
109description of their behavior.  If the CONFIG_FEATURE_VERBOSE_USAGE option has
110been enabled, more detailed usage information will also be available.</p>

781<h1><a name="libc_nss">LIBC NSS</a></h1>
782<p>GNU Libc (glibc) uses the Name Service Switch (NSS) to configure the behavior
783of the C library for the local environment, and to configure how it reads
784system data, such as passwords and group information.  This is implemented
785using an /etc/nsswitch.conf configuration file, and using one or more of the
786/lib/libnss_* libraries.  BusyBox tries to avoid using any libc calls that make
787use of NSS.  Some applets however, such as login and su, will use libc functions
788that require NSS.</p>
789<p>If you enable CONFIG_USE_BB_PWD_GRP, BusyBox will use internal functions to
790directly access the /etc/passwd, /etc/group, and /etc/shadow files without
791using NSS.  This may allow you to run your system without the need for
792installing any of the NSS configuration files and libraries.</p>
793<p>When used with glibc, the BusyBox 'networking' applets will similarly require
794that you install at least some of the glibc NSS stuff (in particular,
795/etc/nsswitch.conf, /lib/libnss_dns*, /lib/libnss_files*, and /lib/libresolv*).</p>
796<p>Shameless Plug: As an alternative, one could use a C library such as uClibc.  In
797addition to making your system significantly smaller, uClibc does not require the
798use of any NSS support files or libraries.</p>
