INSERT
config ADJTIMEX
bool "adjtimex"
default y
select PLATFORM_LINUX
help
Adjtimex reads and optionally sets adjustment parameters for
the Linux clock adjustment algorithm.
config BBCONFIG
bool "bbconfig"
default n
help
The bbconfig applet will print the config file with which
busybox was built.
config FEATURE_COMPRESS_BBCONFIG
bool "Compress bbconfig data"
default y
depends on BBCONFIG
help
Store bbconfig data in compressed form, uncompress them on-the-fly
before output.
If you have a really tiny busybox with few applets enabled (and
bunzip2 isn't one of them), the overhead of the decompressor might
be noticeable. Also, if you run executables directly from ROM
and have very little memory, this might not be a win. Otherwise,
you probably want this.
config BEEP
bool "beep"
default y
select PLATFORM_LINUX
help
The beep applets beeps in a given freq/Hz.
config FEATURE_BEEP_FREQ
int "default frequency"
range 0 2147483647
default 4000
depends on BEEP
help
Frequency for default beep.
config FEATURE_BEEP_LENGTH_MS
int "default length"
range 0 2147483647
default 30
depends on BEEP
help
Length in ms for default beep.
config CHAT
bool "chat"
default y
help
Simple chat utility.
config FEATURE_CHAT_NOFAIL
bool "Enable NOFAIL expect strings"
depends on CHAT
default y
help
When enabled expect strings which are started with a dash trigger
no-fail mode. That is when expectation is not met within timeout
the script is not terminated but sends next SEND string and waits
for next EXPECT string. This allows to compose far more flexible
scripts.
config FEATURE_CHAT_TTY_HIFI
bool "Force STDIN to be a TTY"
depends on CHAT
default n
help
Original chat always treats STDIN as a TTY device and sets for it
so-called raw mode. This option turns on such behaviour.
config FEATURE_CHAT_IMPLICIT_CR
bool "Enable implicit Carriage Return"
depends on CHAT
default y
help
When enabled make chat to terminate all SEND strings with a "\r"
unless "\c" is met anywhere in the string.
config FEATURE_CHAT_SWALLOW_OPTS
bool "Swallow options"
depends on CHAT
default y
help
Busybox chat require no options. To make it not fail when used
in place of original chat (which has a bunch of options) turn
this on.
config FEATURE_CHAT_SEND_ESCAPES
bool "Support weird SEND escapes"
depends on CHAT
default y
help
Original chat uses some escape sequences in SEND arguments which
are not sent to device but rather performs special actions.
E.g. "\K" means to send a break sequence to device.
"\d" delays execution for a second, "\p" -- for a 1/100 of second.
Before turning this option on think twice: do you really need them?
config FEATURE_CHAT_VAR_ABORT_LEN
bool "Support variable-length ABORT conditions"
depends on CHAT
default y
help
Original chat uses fixed 50-bytes length ABORT conditions. Say N here.
config FEATURE_CHAT_CLR_ABORT
bool "Support revoking of ABORT conditions"
depends on CHAT
default y
help
Support CLR_ABORT directive.
config CHRT
bool "chrt"
default y
help
manipulate real-time attributes of a process.
This requires sched_{g,s}etparam support in your libc.
config CROND
bool "crond"
default y
select FEATURE_SYSLOG
help
Crond is a background daemon that parses individual crontab
files and executes commands on behalf of the users in question.
This is a port of dcron from slackware. It uses files of the
format /var/spool/cron/crontabs/<username> files, for example:
$ cat /var/spool/cron/crontabs/root
# Run daily cron jobs at 4:40 every day:
40 4 * * * /etc/cron/daily > /dev/null 2>&1
config FEATURE_CROND_D
bool "Support option -d to redirect output to stderr"
depends on CROND
default y
help
-d sets loglevel to 0 (most verbose) and directs all output to stderr.
config FEATURE_CROND_CALL_SENDMAIL
bool "Report command output via email (using sendmail)"
default y
depends on CROND
help
Command output will be sent to corresponding user via email.

default "/var/spool/cron"
depends on CROND || CRONTAB
help

the superuser may specify a different user and/or crontab directory.
Note that Busybox binary must be setuid root for this applet to
work properly.
config DC
bool "dc"
default y
help
Dc is a reverse-polish desk calculator which supports unlimited
precision arithmetic.
config FEATURE_DC_LIBM
bool "Enable power and exp functions (requires libm)"
default y

NOTE: This will require libm to be present for linking.
config DEVFSD
bool "devfsd (obsolete)"
default n
select PLATFORM_LINUX
select FEATURE_SYSLOG
help
This is deprecated and should NOT be used anymore.
Use linux >= 2.6 (optionally with hotplug) and mdev instead!
See docs/mdev.txt for detailed instructions on how to use mdev
instead.
Provides compatibility with old device names on a devfs systems.
You should set it to true if you have devfs enabled.
The following keywords in devsfd.conf are supported:
"CLEAR_CONFIG", "INCLUDE", "OPTIONAL_INCLUDE", "RESTORE",
"PERMISSIONS", "EXECUTE", "COPY", "IGNORE",
"MKOLDCOMPAT", "MKNEWCOMPAT","RMOLDCOMPAT", "RMNEWCOMPAT".
But only if they are written UPPERCASE!!!!!!!!
config DEVFSD_MODLOAD
bool "Adds support for MODLOAD keyword in devsfd.conf"
default y

the external modutils.

bool "Enables the -fg and -np options"
default y
depends on DEVFSD
help
-fg Run the daemon in the foreground.
-np Exit after parsing the configuration file.

config FEATURE_DEVFS
bool "Use devfs names for all devices (obsolete)"
default n
select PLATFORM_LINUX
help
This is obsolete and should NOT be used anymore.
Use linux >= 2.6 (optionally with hotplug) and mdev instead!
For legacy systems -- if there is no way around devfsd -- this
tells busybox to look for names like /dev/loop/0 instead of
/dev/loop0. If your /dev directory has normal names instead of
devfs names, you don't want this.
config DEVMEM
bool "devmem"
default y
help
devmem is a small program that reads and writes from physical
memory using /dev/mem.
config EJECT
bool "eject"
default y
select PLATFORM_LINUX

usb-storage devices.
config FBSPLASH

Can be used during boot phase of an embedded device. ~2kb.
Usage:
- use kernel option 'vga=xxx' or otherwise enable fb device.
- put somewhere fbsplash.cfg file and an image in .ppm format.
- $ setsid fbsplash [params] &

"NN" (ASCII decimal number) - percentage to show on progress bar
"exit" - well you guessed it

bool "Support obtaining detailed information directly from drives"
default y
depends on HDPARM

identify data from stdin. Enabling this option will add about 16k...
config FEATURE_HDPARM_HDIO_SCAN_HWIF
bool "Register an IDE interface (DANGEROUS)"
default y
depends on HDPARM
help
Enables the 'hdparm -R' option to register an IDE interface.
This is dangerous stuff, so you should probably say N.

config MAKEDEVS
bool "makedevs"
default y
help
'makedevs' is a utility used to create a batch of devices with
one command.
There are two choices for command line behaviour, the interface
as used by LEAF/Linux Router Project, or a device table file.
'leaf' is traditionally what busybox follows, it allows multiple
devices of a particluar type to be created per command.
e.g. /dev/hda[0-9]
Device properties are passed as command line arguments.
'table' reads device properties from a file or stdin, allowing
a batch of unrelated devices to be made with one command.
User/group names are allowed as an alternative to uid/gid.
choice

help
raidautorun tells the kernel md driver to
search and start RAID arrays.
config READAHEAD
bool "readahead"
default y
depends on LFS
select PLATFORM_LINUX
help
Preload the files listed on the command line into RAM cache so that
subsequent reads on these files will not block on disk I/O.
This applet just calls the readahead(2) system call on each file.
It is mainly useful in system startup scripts to preload files
or executables before they are used. When used at the right time
(in particular when a CPU bound process is running) it can
significantly speed up system startup.
As readahead(2) blocks until each file has been read, it is best to
run this applet as a background job.
config RFKILL

and adds about 135 Bytes. May be needed for machines with alot
of CPUs.
config TIME

The watchdog utility is used with hardware or software watchdog
device drivers. It opens the specified watchdog device special file
and periodically writes a magic character to the device. If the
watchdog applet ever fails to write the magic character within a
certain amount of time, the watchdog device assumes the system has
hung, and will cause the hardware to reboot.
