BUSYBOX(1)			    busybox			    BUSYBOX(1)

       BusyBox - The Swiss Army Knife of Embedded Linux

	busybox <applet> [arguments...]	 # or

	<applet> [arguments...]		 # if symlinked

       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

       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.
       Then run 'make' to compile BusyBox using your configuration.

       After the compile has finished, you should use 'make install' to
       install BusyBox. This will install the 'bin/busybox' binary, in the
       target directory specified by CONFIG_PREFIX. CONFIG_PREFIX can be set
       when configuring BusyBox, or you can specify an alternative location at
       install time (i.e., with a command line like 'make
       CONFIG_PREFIX=/tmp/foo install'). If you enabled any applet
       installation scheme (either as symlinks or hardlinks), these will also
       be installed in the location pointed to by CONFIG_PREFIX.

       BusyBox is a multi-call binary.	A multi-call binary is an executable
       program that performs the same job as more than one utility program.
       That means there is just a single BusyBox binary, but that single
       binary acts like a large number of utilities.  This allows BusyBox to
       be smaller since all the built-in utility programs (we call them
       applets) can share code for many common operations.

       You can also invoke BusyBox by issuing a command as an argument on the
       command line.  For example, entering

	       /bin/busybox ls

       will also cause BusyBox to behave as 'ls'.

       Of course, adding '/bin/busybox' into every command would be painful.
       So most people will invoke BusyBox using links to the BusyBox binary.

       For example, entering

	       ln -s /bin/busybox ls

       will cause BusyBox to behave as 'ls' (if the 'ls' command has been
       compiled into BusyBox).	Generally speaking, you should never need to
       make all these links yourself, as the BusyBox build system will do this
       for you when you run the 'make install' command.

       If you invoke BusyBox with no arguments, it will provide you with a
       list of the applets that have been compiled into your BusyBox binary.

       Most BusyBox applets support the --help argument to provide a terse
       runtime description of their behavior.  If the
       CONFIG_FEATURE_VERBOSE_USAGE option has been enabled, more detailed
       usage information will also be available.

	   mdev [-s]

	   mdev -s is to be run during boot to scan /sys and populate /dev.

	   Bare mdev is a kernel hotplug helper. To activate it:      echo
	   /sbin/mdev >/proc/sys/kernel/hotplug

	   It uses /etc/mdev.conf with lines	  [-][ENV=regex;]...DEVNAME
	   UID:GID PERM [>|=PATH]|[!] [@|$|*PROG] where DEVNAME is device name
	   regex, @major,minor[-minor2], or environment variable regex. A
	   common use of the latter is to load modules for hotplugged devices:

		   $MODALIAS=.* 0:0 660 @modprobe "$MODALIAS"

	   If /dev/mdev.seq file exists, mdev will wait for its value to match
	   $SEQNUM variable. This prevents plug/unplug races.  To activate
	   this feature, create empty /dev/mdev.seq at boot.

	   If /dev/mdev.log file exists, debug log will be appended to it.

       GNU Libc (glibc) uses the Name Service Switch (NSS) to configure the
       behavior of the C library for the local environment, and to configure
       how it reads system data, such as passwords and group information.
       This is implemented using an /etc/nsswitch.conf configuration file, and
       using one or more of the /lib/libnss_* libraries.  BusyBox tries to
       avoid using any libc calls that make use of NSS.	 Some applets however,
       such as login and su, will use libc functions that require NSS.

       If you enable CONFIG_USE_BB_PWD_GRP, BusyBox will use internal
       functions to directly access the /etc/passwd, /etc/group, and
       /etc/shadow files without using NSS.  This may allow you to run your
       system without the need for installing any of the NSS configuration
       files and libraries.

       When used with glibc, the BusyBox 'networking' applets will similarly
       require that you install at least some of the glibc NSS stuff (in
       particular, /etc/nsswitch.conf, /lib/libnss_dns*, /lib/libnss_files*,
       and /lib/libresolv*).

       Shameless Plug: As an alternative, one could use a C library such as
       uClibc.	In addition to making your system significantly smaller,
       uClibc does not require the use of any NSS support files or libraries.

       The following people have contributed code to BusyBox whether they know
       it or not.  If you have written code included in BusyBox, you should
       probably be listed here so you can obtain your bit of eternal glory.
       If you should be listed here, or the description of what you have done
       needs more detail, or is incorrect, please send in an update.
