menu "Miscellaneous Utilities"
config ADJTIMEX
bool "adjtimex"
default n
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 CHAT
bool "chat"
default n
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"

default n
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 n
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 n
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 n
help
Support CLR_ABORT directive.
config CHRT
bool "chrt"

bool "crond"
default n
select FEATURE_SUID
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 DEBUG_CROND_OPTION
bool "Support option -d to redirect output to stderr"
depends on CROND
default n
help
-d sets loglevel to 0 (most verbose) and directs all output to stderr.
config FEATURE_CROND_CALL_SENDMAIL
bool "Using /usr/sbin/sendmail?"
default n
depends on CROND
help
Support calling /usr/sbin/sendmail for send cmd outputs.
config CRONTAB
bool "crontab"
default n
select FEATURE_SUID
help
Crontab manipulates the crontab for a particular user. Only
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 n
help
Dc is a reverse-polish desk calculator which supports unlimited
precision arithmetic.
config DEVFSD
bool "devfsd (obsolete)"
default n
select FEATURE_SYSLOG
help
This is deprecated, and will be removed at the end of 2008.
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 n
depends on DEVFSD
help
This actually doesn't work with busybox modutils but needs
the external modutils.
config DEVFSD_FG_NP
bool "Enables the -fg and -np options"
default n
depends on DEVFSD
help
-fg Run the daemon in the foreground.
-np Exit after parsing the configuration file. Do not poll for events.
config DEVFSD_VERBOSE
bool "Increases logging (and size)"
default n
depends on DEVFSD
help
Increases logging to stderr or syslog.
config FEATURE_DEVFS
bool "Use devfs names for all devices (obsolete)"
default n
help
This is obsolete and will be going away at the end of 2008..
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.

grep -q "fbsplash=on" </proc/cmdline && setsid fbsplash [params] &
- commands for fifo:
"NN" (ASCII decimal number) - percentage to show on progress bar
"exit" (or just close fifo) - well you guessed it

FEATURE_HDPARM_GET_IDENTITY option)....
config FEATURE_HDPARM_GET_IDENTITY
bool "Support obtaining detailed information directly from drives"
default y
depends on HDPARM
help
Enables the -I and -i options to obtain detailed information
directly from drives about their capabilities and supported ATA
feature set. If no device name is specified, hdparm will read
identify data from stdin. Enabling this option will add about 16k...
config FEATURE_HDPARM_HDIO_SCAN_HWIF
bool "Register an IDE interface (DANGEROUS)"
default n
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 FEATURE_HDPARM_HDIO_UNREGISTER_HWIF
bool "Un-register an IDE interface (DANGEROUS)"
default n
depends on HDPARM
help
Enables the 'hdparm -U' option to un-register an IDE interface.

default n
depends on HDPARM
help
Enables the 'hdparm -x' option to tristate device for hotswap,

bool "get/set using_dma flag (DANGEROUS)"
default n
depends on HDPARM
help
Enables the 'hdparm -d' option to get/set using_dma flag.
This is dangerous stuff, so you should probably say N.
config MAKEDEVS
bool "makedevs"
default n
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.

files on the tape.
config RAIDAUTORUN
bool "raidautorun"
default n
help
raidautorun tells the kernel md driver to
search and start RAID arrays.
config READAHEAD
bool "readahead"
default n
depends on LFS
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 boundprocess 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 RUNLEVEL
bool "runlevel"
default n
help
find the current and previous system runlevel.
This applet uses utmp but does not rely on busybox supporing
utmp on purpose. It is used by e.g. emdebian via /etc/init.d/rc.
config RX

default n
help
Receive files using the Xmodem protocol.
config SCRIPT

config FEATURE_TASKSET_FANCY
bool "Fancy output"
default y
depends on TASKSET
help
Add code for fancy output. This merely silences a compiler-warning
and adds about 135 Bytes. May be needed for machines with alot
of CPUs.
config TIME
bool "time"
default n
help
The time command runs the specified program with the given arguments.
When the command finishes, time writes a message to standard output
giving timing statistics about this program run.
config TTYSIZE
bool "ttysize"
default n
help
A replacement for "stty size". Unlike stty, can report only width,
only height, or both, in any order. It also does not complain on error,
but returns default 80x24. Usage in shell scripts: width=`ttysize w`.
config WATCHDOG
bool "watchdog"
default n
help
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.
