config TOYBOX
bool
default y
help
usage: toybox [--long | --help | --version | [command] [arguments...]]
With no arguments, shows available commands. First argument is
name of a command to run, followed by any arguments to that command.
--long Show path to each command
To install command symlinks with paths, try:
for i in $(/bin/toybox --long); do ln -s /bin/toybox $i; done
or all in one directory:
for i in $(./toybox); do ln -s toybox $i; done; PATH=$PWD:$PATH
Most toybox commands also understand the following arguments:
--help Show command help (only)
--version Show toybox version (only)
The filename "-" means stdin/stdout, and "--" stops argument parsing.
Numerical arguments accept a single letter suffix for
kilo, mega, giga, tera, peta, and exabytes, plus an additional
"d" to indicate decimal 1000's instead of 1024.
Durations can be decimal fractions and accept minute ("m"), hour ("h"),
or day ("d") suffixes (so 0.1m = 6s).
config TOYBOX_SUID
bool "SUID support"
default y
help
Support for the Set User ID bit, to install toybox suid root and drop
permissions for commands which do not require root access. To use
this change ownership of the file to the root user and set the suid
bit in the file permissions:
chown root:root toybox; chmod +s toybox
choice
prompt "Security Blanket"
default TOYBOX_LSM_NONE
help
Select a Linux Security Module to complicate your system
until you can't find holes in it.
config TOYBOX_LSM_NONE
bool "None"
help
Don't try to achieve "watertight" by plugging the holes in a
collander, instead use conventional unix security (and possibly
Linux Containers) for a simple straightforward system.
config TOYBOX_SELINUX
bool "SELinux support"
help
Include SELinux options in commands such as ls, and add
SELinux-specific commands such as chcon to the Android menu.
config TOYBOX_SMACK
bool "SMACK support"
help
Include SMACK options in commands like ls for systems like Tizen.
endchoice
config TOYBOX_LIBCRYPTO
bool "Use libcrypto (OpenSSL/BoringSSL)"
default n
help
Use faster hash functions out of external -lcrypto library.
config TOYBOX_LIBZ
bool "Use libz (zlib)"
default n
help
Use libz for gz support.
config TOYBOX_FLOAT
bool "Floating point support"
default y
help
Include floating point support infrastructure and commands that
require it.
config TOYBOX_HELP
bool "Help messages"
default y
help
Include help text for each command.
config TOYBOX_HELP_DASHDASH
bool "--help and --version"
default y
depends on TOYBOX_HELP
help
Support --help argument in all commands, even ones with a NULL
optstring. (Use TOYFLAG_NOHELP to disable.) Produces the same output
as "help command". --version shows toybox version.
config TOYBOX_I18N
bool "Internationalization support"
default y
help
Support for UTF-8 character sets, and some locale support.
config TOYBOX_FREE
bool "Free memory unnecessarily"
default n
help
When a program exits, the operating system will clean up after it
(free memory, close files, etc). To save size, toybox usually relies
on this behavior. If you're running toybox under a debugger or
without a real OS (ala newlib+libgloss), enable this to make toybox
clean up after itself.
config TOYBOX_NORECURSE
bool "Disable recursive execution"
default n
help
When one toybox command calls another, usually it just calls the new
command's main() function rather than searching the $PATH and calling
exec on another file (which is much slower).
This disables that optimization, so toybox will run external commands
even when it has a built-in version of that command. This requires
toybox symlinks to be installed in the $PATH, or re-invoking the
"toybox" multiplexer command by name.
config TOYBOX_DEBUG
bool "Debugging tests"
default n
help
Enable extra checks for debugging purposes. All of them catch
things that can only go wrong at development time, not runtime.
config TOYBOX_PEDANTIC_ARGS
bool "Pedantic argument checking"
default n
help
Check arguments for commands that have no arguments.
config TOYBOX_UID_SYS
int "First system UID"
default 100
help
When commands like useradd/groupadd allocate system IDs, start here.
config TOYBOX_UID_USR
int "First user UID"
default 500
help
When commands like useradd/groupadd allocate user IDs, start here.
config TOYBOX_MUSL_NOMMU_IS_BROKEN
bool "Workaround for musl-libc breakage on nommu systems."
default n
help
When using musl-libc on a nommu system, you'll need to say "y" here.
Although uclibc lets you detect support for things like fork() and
daemon() at compile time, musl intentionally includes broken versions
that always return -ENOSYS on nommu systems, and goes out of its way
to prevent any cross-compile compatible compile-time probes for a
nommu system. (It doesn't even #define __MUSL__ in features.h.)
Musl does this despite the fact that a nommu system can't even run
standard ELF binaries, and requires specially packaged executables.
So our only choice is to manually provide a musl nommu bug workaround
you can manually select to enable (larger, slower) nommu support with
musl.

Toybox: all-in-one Linux command line.
--- Getting started
You can download static binaries for various targets from:
http://landley.net/toybox/bin
The special name "." indicates the current directory (just like ".." means
the parent directory), and you can run a program that isn't in the $PATH by
specifying a path to it, so this should work:
wget http://landley.net/toybox/bin/toybox-x86_64
chmod +x toybox-x86_64
./toybox-x86_64 echo hello world
--- Building toybox
Type "make help" for build instructions.
Toybox uses the "make menuconfig; make; make install" idiom same as
the Linux kernel. Usually you want something like:
make defconfig
make
make install
Or maybe:
LDFLAGS="--static" CROSS_COMPILE=armv5l- make defconfig toybox
PREFIX=/path/to/root/filesystem/bin make install_flat
The file "configure" defines default values for many environment
variables that control the toybox build; if you set a value for any of
these, your value is used instead of the default in that file.
The CROSS_COMPILE argument above is optional, the default builds a version of
toybox to run on the current machine. Cross compiling requires an appropriately
prefixed cross compiler toolchain, several example toolchains are available at:
http://landley.net/aboriginal/bin
For the "CROSS_COMPILE=armv5l-" example above, download
cross-compiler-armv5l.tar.bz2, extract it, and add its "bin" subdirectory to
your $PATH. (And yes, the trailing - is significant, because the prefix
includes a dash.)
For more about cross compiling, see:
http://landley.net/writing/docs/cross-compiling.html
http://landley.net/aboriginal/architectures.html
For a more thorough description of the toybox build process, see
http://landley.net/toybox/code.html#building
--- Using toybox
The toybox build produces a multicall binary, a "swiss-army-knife" program
that acts differently depending on the name it was called by (cp, mv, cat...).
Installing toybox adds symlinks for each command name to the $PATH.
The special "toybox" command treats its first argument as the command to run.
With no arguments, it lists available commands. This allows you to use toybox
without installing it. This is the only command that can have an arbitrary
suffix (hence "toybox-armv5l").
The "help" command provides information about each command (ala "help cat").
--- Configuring toybox
It works like the Linux kernel: allnoconfig, defconfig, and menuconfig edit
a ".config" file that selects which features to include in the resulting
binary. You can save and re-use your .config file, although may want to
run "make oldconfig" to re-run the dependency resolver when migrating to
new versions.
The maximum sane configuration is "make defconfig": allyesconfig isn't
recommended for toybox because it enables unfinished commands and debug code.
--- Creating a Toybox-based Linux system
Toybox is not a complete operating system, it's a program that runs under
an operating system. Booting a simple system to a shell prompt requires
three packages: an operating system kernel (Linux*) to drive the hardware,
one or more programs for the system to run (toybox), and a C library ("libc")
to tie them together (toybox has been tested with musl, uClibc, glibc,
and bionic).
The C library is part of a "toolchain", which is an integrated suite
of compiler, assembler, and linker, plus the standard headers and libraries
necessary to build C programs. (And miscellaneous binaries like nm and objdump.)
Static linking (with the --static option) copies the shared library contents
into the program, resulting in larger but more portable programs, which
can run even if they're the only file in the filesystem. Otherwise,
the "dynamically" linked programs require the library files to be present on
the target system ("man ldd" and "man ld.so" for details).
An example toybox-based system is Aboriginal Linux:
http://landley.net/aboriginal/about.html
That's designed to run under qemu, emulating several different hardware
architectures (x86, x86-64, arm, mips, sparc, powerpc, sh4). Each toybox
release is regression tested by building Linux From Scratch under this
toybox-based system on each supported architecture, using QEMU to emulate
big and little endian systems with different word size and alignment
requirements. (The eventual goal is to replace Linux From Scratch with
the Android Open Source Project.)
* Or something providing the same API such as FreeBSD's Linux emulation layer.

--- Contributing
The three important URLs for communicating with the toybox project are:
web page: http://landley.net/toybox
mailing list: http://lists.landley.net/listinfo.cgi/toybox-landley.net
git repo: http://github.com/landley/toybox
The maintainer prefers patches be sent to the mailing list. If you use git,
the easy thing to do is:
git format-patch -1 $HASH
Then send a file attachment. The list holds messages from non-subscribers
for moderation, but I usually get to them in a day or two.
Although I do accept pull requests on github, I download the patches and
apply them with "git am" (which avoids gratuitous merge commits). Closing
the pull request is then the submitter's responsibility.
If I haven't responded to your patch after one week, feel free to remind
me of it.
Android's policy for toybox patches is that non-build patches should go
upstream first (into vanilla toybox, with discussion on the toybox mailing
list) and then be pulled into android's toybox repo from there. (They
generally resync on fridays). The exception is patches to their build scripts
(Android.mk and the checked-in generated/* files) which go directly to AOSP.

This is a snapshot of linux 2.6.12 kconfig as washed through busybox and
further modified by Rob Landley.
Note: The build infrastructure in this directory is still GPLv2. Cleaning
that out is a TODO item, but it doesn't affect the resulting binary.
Way back when I tried to push my local changes to kconfig upstream
in 2005 https://lwn.net/Articles/161086/
and 2006 http://lkml.iu.edu/hypermail/linux/kernel/0607.0/1805.html
and 2007 http://lkml.iu.edu/hypermail/linux/kernel/0707.1/1741.html
each of which spawned long "I think you should go do this and this and this
but I'm not going to lift a finger personally" threads from the kernel
developers. Twice I came back a year later to see if there was any interest
in what I _had_ done, and the third thread was the longest of the lot but
no code was merged as a result.
*shrug* That's the linux-kernel community for you. I had an easier time
than the author of squashfs, who spent 5 years actively trying to get his code
merged, finally quitting his job to spend an unpaid year working on upstreaming
squashfs _after_ after every major Linux distro had been locally carrying it
for years. No really, here's where he wrote about it himself:
https://lwn.net/Articles/563578/
This code is _going_away_. Rewriting it is low priority, but removing it is a
checklist item for the 1.0 toybox release. This directory contains the only
GPL code left in the tree, and none of its code winds up in the resulting
binary. It's just an editor that reads our Config.in files to update the top
level .config file; you can edit they by hand if you really want to.

/*
* Changes by Clifford Wolf (god@clifford.at)
*
* [ 1998-06-13 ]
*
* *) A bugfix for the Page-Down problem
*
* *) Formerly when I used Page Down and Page Up, the cursor would be set
* to the first position in the menu box. Now lxdialog is a bit
* smarter and works more like other menu systems (just have a look at
* it).
*
* *) Formerly if I selected something my scrolling would be broken because
* lxdialog is re-invoked by the Menuconfig shell script, can't
* remember the last scrolling position, and just sets it so that the
* cursor is at the bottom of the box. Now it writes the temporary file
* lxdialog.scrltmp which contains this information. The file is
* deleted by lxdialog if the user leaves a submenu or enters a new
* one, but it would be nice if Menuconfig could make another "rm -f"
* just to be sure. Just try it out - you will recognise a difference!
*
* [ 1998-06-14 ]
*
* *) Now lxdialog is crash-safe against broken "lxdialog.scrltmp" files
* and menus change their size on the fly.
*
* *) If for some reason the last scrolling position is not saved by
* lxdialog, it sets the scrolling so that the selected item is in the
* middle of the menu box, not at the bottom.
*
* 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
* Reset 'scroll' to 0 if the value from lxdialog.scrltmp is bogus.
* This fixes a bug in Menuconfig where using ' ' to descend into menus
* would leave mis-synchronized lxdialog.scrltmp files lying around,
* fscanf would read in 'scroll', and eventually that value would get used.

// add syntax checks to option string parsing which aren't needed in the final
// code (since get_opt string is hardwired and should be correct when you ship)
#include "toys.h"
// Design goals:
// Don't use getopt() out of libc.
// Don't permute original arguments (screwing up ps/top output).
// Integrated --long options "(noshort)a(along)b(blong1)(blong2)"
/* This uses a getopt-like option string, but not getopt() itself. We call
* it the get_opt string.
*
* Each option in the get_opt string corresponds to a bit position in the
* return value. The rightmost argument is (1<<0), the next to last is (1<<1)
* and so on. If the option isn't seen in argv[], its bit remains 0.
*
* Options which have an argument fill in the corresponding slot in the global
* union "this" (see generated/globals.h), which it treats as an array of longs
* (note that sizeof(long)==sizeof(pointer) is guaranteed by LP64).
*
* You don't have to free the option strings, which point into the environment
* space. List objects should be freed by main() when command_main() returns.
*
* Example:
* Calling get_optflags() when toys.which->options="ab:c:d" and
* argv = ["command", "-b", "fruit", "-d", "walrus"] results in:
*
* Changes to struct toys:
* toys.optflags = 5 (I.E. 0101 so -b = 4 | -d = 1)
* toys.optargs[0] = "walrus" (leftover argument)
* toys.optargs[1] = NULL (end of list)
* toys.optc = 1 (there was 1 leftover argument)
*
* Changes to union this:
* this[0]=NULL (because -c didn't get an argument this time)
* this[1]="fruit" (argument to -b)
*/
// What you can put in a get_opt string:
// Any otherwise unused character (all letters, unprefixed numbers) specify
// an option that sets a flag. The bit value is the same as the binary digit
// if you string the option characters together in order.
// So in "abcdefgh" a = 128, h = 1
//
// Suffixes specify that this option takes an argument (stored in GLOBALS):
// Note that pointer and long are always the same size, even on 64 bit.
// : string argument, keep most recent if more than one
// * string argument, appended to a struct arg_list linked list.
// # signed long argument
// <LOW - die if less than LOW
// >HIGH - die if greater than HIGH
// =DEFAULT - value if not specified
// - signed long argument defaulting to negative (say + for positive)
// . double precision floating point argument (with CFG_TOYBOX_FLOAT)
// Chop this option out with USE_TOYBOX_FLOAT() in option string
// Same <LOW>HIGH=DEFAULT as #
// @ occurrence counter (which is a long)
// % time offset in milliseconds with optional s/m/h/d suffix
// (longopt)
// | this is required. If more than one marked, only one required.
// ; long option's argument is optional (can only be supplied with --opt=)
// ^ Stop parsing after encountering this argument
// " " (space char) the "plus an argument" must be separate
// I.E. "-j 3" not "-j3". So "kill -stop" != "kill -s top"
//
// At the beginning of the get_opt string (before any options):
// ^ stop at first nonoption argument
// <0 die if less than # leftover arguments (default 0)
// >9 die if > # leftover arguments (default MAX_INT)
// ? Allow unknown arguments (pass them through to command).
// & first arg has imaginary dash (ala tar/ps/ar) which sets FLAGS_NODASH
//
// At the end: [groups] of previously seen options
// - Only one in group (switch off) [-abc] means -ab=-b, -ba=-a, -abc=-c
// + Synonyms (switch on all) [+abc] means -ab=-abc, -c=-abc
// ! More than one in group is error [!abc] means -ab calls error_exit()
// primarily useful if you can switch things back off again.
//
// You may use octal escapes with the high bit (127) set to use a control
// character as an option flag. For example, \300 would be the option -@
// Notes from getopt man page
// - and -- cannot be arguments.
// -- force end of arguments
// - is a synonym for stdin in file arguments
// -abcd means -a -b -c -d (but if -b takes an argument, then it's -a -b cd)

# Simple test harness infrastructure
#
# Copyright 2005 by Rob Landley
# This file defines two main functions, "testcmd" and "optional". The
# first performs a test, the second enables/disables tests based on
# configuration options.
# The following environment variables enable optional behavior in "testing":
# DEBUG - Show every command run by test script.
# VERBOSE - Print the diff -u of each failed test case.
# If equal to "fail", stop after first failed test.
# "nopass" to not show successful tests
#
# The "testcmd" function takes five arguments:
# $1) Description to display when running command
# $2) Command line arguments to command
# $3) Expected result (on stdout)
# $4) Data written to file "input"
# $5) Data written to stdin
#
# The "testing" function is like testcmd but takes a complete command line
# (I.E. you have to include the command name.) The variable $C is an absolute
# path to the command being tested, which can bypass shell builtins.
#
# The exit value of testcmd is the exit value of the command it ran.
#
# The environment variable "FAILCOUNT" contains a cumulative total of the
# number of failed tests.
#
# The "optional" function is used to skip certain tests (by setting the
# environment variable SKIP), ala:
# optional CFG_THINGY
#
# The "optional" function checks the environment variable "OPTIONFLAGS",
# which is either empty (in which case it always clears SKIP) or
# else contains a colon-separated list of features (in which case the function
# clears SKIP if the flag was found, or sets it to 1 if the flag was not found).

The build infrastructure adds a "make test_NAME" target for each NAME.test
file in this directory, and "make tests" iterates through all of them.
Individual tests boil down to a call to "scripts/test.sh NAME", and
testing all is "scripts/test.sh" with no arguments.
The test infrastructure, including the shell functions each test calls
(mostly "testcmd" and "optional") is described in scripts/test.sh
