=head1 NAME

BusyBox - The Swiss Army Knife of Embedded Linux

=head1 SYNTAX

 BusyBox <function> [arguments...]  # or

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

=head1 DESCRIPTION

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 a kernel, a shell (such as ash),
and an editor (such as elvis-tiny or ae).

=head1 USAGE

When you create a link to BusyBox for the function you wish to use, when BusyBox
is called using that link it will behave as if the command itself has been invoked.

For example, entering

	ln -s ./BusyBox ls
	./ls

will cause BusyBox to behave as 'ls' (if the 'ls' command has been compiled
into BusyBox). 

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

	./BusyBox ls

will also cause BusyBox to behave as 'ls'. 

=head1 COMMON OPTIONS

Most BusyBox commands support the B<--help> option to provide a
terse runtime description of their behavior.

-------------------------------

=item chmod

Usage: chmod [B<-R>] MODE[,MODE]... FILE...

Changes file access permissions for the specified FILE(s) (or directories).
Each MODE is defined by combining the letters for WHO has access to the file,
an OPERATOR for selecting how the permissions should be changed, and a
PERMISSION for FILE(s) (or directories).

WHO may be chosen from

	u	User who owns the file
	g	Users in the file's Group

OPERATOR may be chosen from

	+	Add a permission

	t	Sticky bit (for directories prevents removing files by non-owners)

Alternately, permissions can be set numerically where the first three
numbers are calculated by adding the octal values, such as

	4	Read
	2	Write
	1	Execute

An optional fourth digit can also be used to specify

	4	Set user ID
	2	Set group ID
	1	Sticky bit

									keyword like `match' or an operator like `/'
	( EXPRESSION )              value of EXPRESSION

Beware that many operators need to be escaped or quoted for shells.
Comparisons are arithmetic if both ARGs are numbers, else
lexicographical.  Pattern matches return the string matched between
\( and \) or null; if \( and \) are not used, they return the number
of characters matched or 0.

machine.   The  32-bit identifier is intended to be unique
among all UNIX systems in existence. 

-------------------------------

=item hostname

Usage: hostname [OPTION] {hostname | B<-F> file}

Get or set the hostname or DNS domain name. If a hostname is given
(or a file with the B<-F> parameter), the host name will be set.

Options:

	-s              Short
	-i              Addresses for the hostname

-------------------------------

=item init

Usage: init

Init is the parent of all processes.

This version of init is designed to be run only by the kernel.

BusyBox init doesn't support multiple runlevels.  The runlevels field of
the /etc/inittab file is completely ignored by BusyBox init. If you want 
runlevels, use sysvinit.

BusyBox init works just fine without an inittab.  If no inittab is found, 
it has the following default behavior:

	::sysinit:/etc/init.d/rcS
	::askfirst:/bin/sh

if it detects that /dev/console is _not_ a serial console, it will also run:

	tty2::askfirst:/bin/sh

If you choose to use an /etc/inittab file, the inittab entry format is as follows:

	<id>:<runlevels>:<action>:<process>

	<id>: 

		WARNING: This field has a non-traditional meaning for BusyBox init!
		The id field is used by BusyBox init to specify the controlling tty for
		the specified process to run on.  The contents of this field are
		appended to "/dev/" and used as-is.  There is no need for this field to
		be unique, although if it isn't you may have strange results.  If this
		field is left blank, the controlling tty is set to the console.  Also
		note that if BusyBox detects that a serial console is in use, then only
		entries whose controlling tty is either the serial console or /dev/null
		will be run.  BusyBox init does nothing with utmp.  We don't need no
		stinkin' utmp.

	<runlevels>: 

		The runlevels field is completely ignored.

	<action>: 

		Valid actions include: sysinit, respawn, askfirst, wait, 
		once, and ctrlaltdel.


		The available actions can be classified into two groups: actions
		that are run only once, and actions that are re-run when the specified
		process exits.

		Run only-once actions:

			'sysinit' is the first item run on boot.  init waits until all
			sysinit actions are completed before continuing.  Following the
			completion of all sysinit actions, all 'wait' actions are run.
			'wait' actions, like  'sysinit' actions, cause init to wait until
			the specified task completes.  'once' actions are asyncronous,
			therefore, init does not wait for them to complete.  'ctrlaltdel'
			actions are run immediately before init causes the system to reboot
			(unmounting filesystems with a 'ctrlaltdel' action is a very good
			idea).

		Run repeatedly actions:

			'respawn' actions are run after the 'once' actions.  When a process
			started with a 'respawn' action exits, init automatically restarts
			it.  Unlike sysvinit, BusyBox init does not stop processes from
			respawning out of control.  The 'askfirst' actions acts just like
			respawn, except that before running the specified process it
			displays the line "Please press Enter to activate this console."
			and then waits for the user to press enter before starting the
			specified process.  

		Unrecognized actions (like initdefault) will cause init to emit an
		error message, and then go along with its business.  All actions are
		run in the reverse order from how they appear in /etc/inittab.

	<process>: 

		Specifies the process to be executed and it's command line.


Example /etc/inittab file:

	# This is run first except when booting in single-user mode.
	#
	::sysinit:/etc/init.d/rcS

	# /bin/sh invocations on selected ttys
	#
	# Start an "askfirst" shell on the console (whatever that may be)
	::askfirst:-/bin/sh
	# Start an "askfirst" shell on /dev/tty2-4
	tty2::askfirst:-/bin/sh
	tty3::askfirst:-/bin/sh
	tty4::askfirst:-/bin/sh

	# /sbin/getty invocations for selected ttys
	#
	tty4::respawn:/sbin/getty 38400 tty5
	tty5::respawn:/sbin/getty 38400 tty6


	# Example of how to put a getty on a serial line (for a terminal)
	#
	#::respawn:/sbin/getty -L ttyS0 9600 vt100
	#::respawn:/sbin/getty -L ttyS1 9600 vt100
	#
	# Example how to put a getty on a modem line.
	#::respawn:/sbin/getty 57600 ttyS2

	# Stuff to do before rebooting
	::ctrlaltdel:/bin/umount -a -r
	::ctrlaltdel:/sbin/swapoff -a

=head1 LIBC NSS

GNU Libc 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.  BusyBox has made it Policy that it
will never use NSS, and will never use and libc calls that make use of NSS.
This allows you to run an embedded system without the need for installing an
/etc/nsswitch.conf file and without and /lib/libnss_* libraries installed.

If you are using a system that is using a remote LDAP server for authentication
via GNU libc NSS, and you want to use BusyBox, then you will need to adjust the
BusyBox source.  Chances are though, that if you have enough space to install
of that stuff on your system, then you probably want the full GNU utilities.
