28 config FEATURE_CHAT_NOFAIL
29 bool "Enable NOFAIL expect strings"
33 When enabled expect strings which are started with a dash trigger
34 no-fail mode. That is when expectation is not met within timeout
35 the script is not terminated but sends next SEND string and waits
36 for next EXPECT string. This allows to compose far more flexible
39 config FEATURE_CHAT_TTY_HIFI
40 bool "Force STDIN to be a TTY"
44 Original chat always treats STDIN as a TTY device and sets for it
45 so-called raw mode. This option turns on such behaviour.
47 config FEATURE_CHAT_IMPLICIT_CR
48 bool "Enable implicit Carriage Return"
52 When enabled make chat to terminate all SEND strings with a "\r"
53 unless "\c" is met anywhere in the string.
55 config FEATURE_CHAT_SWALLOW_OPTS
56 bool "Swallow options"
60 Busybox chat require no options. To make it not fail when used
61 in place of original chat (which has a bunch of options) turn
64 config FEATURE_CHAT_SEND_ESCAPES
65 bool "Support weird SEND escapes"
69 Original chat uses some escape sequences in SEND arguments which
70 are not sent to device but rather performs special actions.
71 E.g. "\K" means to send a break sequence to device.
72 "\d" delays execution for a second, "\p" -- for a 1/100 of second.
73 Before turning this option on think twice: do you really need them?
75 config FEATURE_CHAT_VAR_ABORT_LEN
76 bool "Support variable-length ABORT conditions"
80 Original chat uses fixed 50-bytes length ABORT conditions. Say N here.
82 config FEATURE_CHAT_CLR_ABORT
83 bool "Support revoking of ABORT conditions"
87 Support CLR_ABORT directive.
93 manipulate real-time attributes of a process.
94 This requires sched_{g,s}etparam support in your libc.

102 Crond is a background daemon that parses individual crontab
103 files and executes commands on behalf of the users in question.
104 This is a port of dcron from slackware. It uses files of the
105 format /var/spool/cron/crontabs/<username> files, for example:
106 $ cat /var/spool/cron/crontabs/root
107 # Run daily cron jobs at 4:40 every day:
108 40 4 * * * /etc/cron/daily > /dev/null 2>&1
110 config DEBUG_CROND_OPTION
111 bool "Support option -d to redirect output to stderr"
115 -d sets loglevel to 0 (most verbose) and directs all output to stderr.
117 config FEATURE_CROND_CALL_SENDMAIL
118 bool "Using /usr/sbin/sendmail?"
122 Support calling /usr/sbin/sendmail for send cmd outputs.
129 Crontab manipulates the crontab for a particular user. Only
130 the superuser may specify a different user and/or crontab directory.
131 Note that Busybox binary must be setuid root for this applet to
138 Dc is a reverse-polish desk calculator which supports unlimited
139 precision arithmetic.
142 bool "devfsd (obsolete)"
144 select FEATURE_SYSLOG
146 This is deprecated, and will be removed at the end of 2008.
148 Provides compatibility with old device names on a devfs systems.
149 You should set it to true if you have devfs enabled.
150 The following keywords in devsfd.conf are supported:
151 "CLEAR_CONFIG", "INCLUDE", "OPTIONAL_INCLUDE", "RESTORE",
152 "PERMISSIONS", "EXECUTE", "COPY", "IGNORE",
153 "MKOLDCOMPAT", "MKNEWCOMPAT","RMOLDCOMPAT", "RMNEWCOMPAT".
155 But only if they are written UPPERCASE!!!!!!!!
157 config DEVFSD_MODLOAD
158 bool "Adds support for MODLOAD keyword in devsfd.conf"
162 This actually doesn't work with busybox modutils but needs
163 the external modutils.
166 bool "Enables the -fg and -np options"
170 -fg Run the daemon in the foreground.
171 -np Exit after parsing the configuration file. Do not poll for events.
173 config DEVFSD_VERBOSE
174 bool "Increases logging (and size)"
178 Increases logging to stderr or syslog.
181 bool "Use devfs names for all devices (obsolete)"
184 This is obsolete and will be going away at the end of 2008..
186 This tells busybox to look for names like /dev/loop/0 instead of
187 /dev/loop0. If your /dev directory has normal names instead of
188 devfs names, you don't want this.
194 Used to eject cdroms. (defaults to /dev/cdrom)
196 config FEATURE_EJECT_SCSI
201 Add the -s option to eject, this allows to eject SCSI-Devices and
208 Shows splash image and progress bar on framebuffer device.
209 Can be used during boot phase of an embedded device. ~2kb.
211 - use kernel option 'vga=xxx' or otherwise enable fb device.
212 - put somewhere fbsplash.cfg file and an image in .ppm format.
213 - $ setsid fbsplash [params] &
215 -d /dev/fbN: framebuffer device (if not /dev/fb0)
216 -s path_to_image_file (can be "-" for stdin)
217 -i path_to_cfg_file (can be "-" for stdin)

220 grep -q "fbsplash=on" </proc/cmdline && setsid fbsplash [params] &
222 "NN" (ASCII decimal number) - percentage to show on progress bar
223 "exit" - well you guessed it
230 'last' displays a list of the last users that logged into the system.
236 'less' is a pager, meaning that it displays text files. It possesses
237 a wide array of features, and is an improvement over 'more'.
239 config FEATURE_LESS_MAXLINES
240 int "Max number of input lines less will try to eat"
244 config FEATURE_LESS_BRACKETS
245 bool "Enable bracket searching"
249 This option adds the capability to search for matching left and right
250 brackets, facilitating programming.
252 config FEATURE_LESS_FLAGS
253 bool "Enable extra flags"
257 The extra flags provided do the following:
259 The -M flag enables a more sophisticated status line.
260 The -m flag enables a simpler status line with a percentage.
262 config FEATURE_LESS_FLAGCS
263 bool "Enable flag changes"
267 This enables the ability to change command-line flags within
270 config FEATURE_LESS_MARKS
275 Marks enable positions in a file to be stored for easy reference.
277 config FEATURE_LESS_REGEXP
278 bool "Enable regular expressions"
282 Enable regular expressions, allowing complex file searches.
288 Get/Set hard drive parameters. Primarily intended for ATA
289 drives. Adds about 13k (or around 30k if you enable the
290 FEATURE_HDPARM_GET_IDENTITY option)....
292 config FEATURE_HDPARM_GET_IDENTITY
293 bool "Support obtaining detailed information directly from drives"
297 Enables the -I and -i options to obtain detailed information
298 directly from drives about their capabilities and supported ATA
299 feature set. If no device name is specified, hdparm will read
300 identify data from stdin. Enabling this option will add about 16k...
302 config FEATURE_HDPARM_HDIO_SCAN_HWIF
303 bool "Register an IDE interface (DANGEROUS)"
307 Enables the 'hdparm -R' option to register an IDE interface.
308 This is dangerous stuff, so you should probably say N.
310 config FEATURE_HDPARM_HDIO_UNREGISTER_HWIF
311 bool "Un-register an IDE interface (DANGEROUS)"
315 Enables the 'hdparm -U' option to un-register an IDE interface.
316 This is dangerous stuff, so you should probably say N.
318 config FEATURE_HDPARM_HDIO_DRIVE_RESET
319 bool "perform device reset (DANGEROUS)"
323 Enables the 'hdparm -w' option to perform a device reset.
324 This is dangerous stuff, so you should probably say N.
326 config FEATURE_HDPARM_HDIO_TRISTATE_HWIF
327 bool "tristate device for hotswap (DANGEROUS)"
331 Enables the 'hdparm -x' option to tristate device for hotswap,
332 and the '-b' option to get/set bus state. This is dangerous
333 stuff, so you should probably say N.
335 config FEATURE_HDPARM_HDIO_GETSET_DMA
336 bool "get/set using_dma flag (DANGEROUS)"
340 Enables the 'hdparm -d' option to get/set using_dma flag.
341 This is dangerous stuff, so you should probably say N.
347 'makedevs' is a utility used to create a batch of devices with
350 There are two choices for command line behaviour, the interface
351 as used by LEAF/Linux Router Project, or a device table file.
353 'leaf' is traditionally what busybox follows, it allows multiple
354 devices of a particluar type to be created per command.
356 Device properties are passed as command line arguments.
358 'table' reads device properties from a file or stdin, allowing
359 a batch of unrelated devices to be made with one command.
360 User/group names are allowed as an alternative to uid/gid.

385 The poor man's minicom utility for chatting with serial port devices.
391 mountpoint checks if the directory is a mountpoint.
397 mt is used to control tape devices. You can use the mt utility
398 to advance or rewind a tape past a specified number of archive
405 raidautorun tells the kernel md driver to
406 search and start RAID arrays.
413 Preload the files listed on the command line into RAM cache so that
414 subsequent reads on these files will not block on disk I/O.
416 This applet just calls the readahead(2) system call on each file.
417 It is mainly useful in system startup scripts to preload files
418 or executables before they are used. When used at the right time
419 (in particular when a CPU bound process is running) it can
420 significantly speed up system startup.
422 As readahead(2) blocks until each file has been read, it is best to
423 run this applet as a background job.
429 find the current and previous system runlevel.
431 This applet uses utmp but does not rely on busybox supporing
432 utmp on purpose. It is used by e.g. emdebian via /etc/init.d/rc.
438 Receive files using the Xmodem protocol.
444 setsid runs a program in a new session
450 strings prints the printable character sequences for each file
457 Retrieve or set a processes's CPU affinity.
458 This requires sched_{g,s}etaffinity support in your libc.
460 config FEATURE_TASKSET_FANCY
465 Add code for fancy output. This merely silences a compiler-warning
466 and adds about 135 Bytes. May be needed for machines with alot
473 The time command runs the specified program with the given arguments.
474 When the command finishes, time writes a message to standard output
475 giving timing statistics about this program run.
481 A replacement for "stty size". Unlike stty, can report only width,
482 only height, or both, in any order. It also does not complain on error,
483 but returns default 80x24. Usage in shell scripts: width=`ttysize w`.
489 The watchdog utility is used with hardware or software watchdog
490 device drivers. It opens the specified watchdog device special file
491 and periodically writes a magic character to the device. If the
492 watchdog applet ever fails to write the magic character within a
493 certain amount of time, the watchdog device assumes the system has
494 hung, and will cause the hardware to reboot.
