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.

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.

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.
172 Do not poll for events.
174 config DEVFSD_VERBOSE
175 bool "Increases logging (and size)"
179 Increases logging to stderr or syslog.
182 bool "Use devfs names for all devices (obsolete)"
185 This is obsolete and will be going away at the end of 2008..
187 This tells busybox to look for names like /dev/loop/0 instead of
188 /dev/loop0. If your /dev directory has normal names instead of
189 devfs names, you don't want this.
195 Used to eject cdroms. (defaults to /dev/cdrom)
197 config FEATURE_EJECT_SCSI
202 Add the -s option to eject, this allows to eject SCSI-Devices and
209 Shows splash image and progress bar on framebuffer device.
210 Can be used during boot phase of an embedded device. ~2kb.
212 - use kernel option 'vga=xxx' or otherwise enable fb device.
213 - put somewhere fbsplash.cfg file and an image in .ppm format.
214 - $ setsid fbsplash [params] &
216 -d /dev/fbN: framebuffer device (if not /dev/fb0)
217 -s path_to_image_file (can be "-" for stdin)
218 -i path_to_cfg_file (can be "-" for stdin)
219 -f path_to_fifo (can be "-" for stdin)
220 - if you want to run it only in presence of kernel parameter:
221 grep -q "fbsplash=on" </proc/cmdline && setsid fbsplash [params] &
223 "NN" (ASCII decimal number) - percentage to show on progress bar

248 This is a small version of last with just the basic set of
251 config FEATURE_LAST_FANCY
254 'last' displays detailed information about the last users that
255 logged into the system (mimics sysvinit last). +900 bytes.
262 'less' is a pager, meaning that it displays text files. It possesses
263 a wide array of features, and is an improvement over 'more'.
265 config FEATURE_LESS_MAXLINES
266 int "Max number of input lines less will try to eat"
270 config FEATURE_LESS_BRACKETS
271 bool "Enable bracket searching"
275 This option adds the capability to search for matching left and right
276 brackets, facilitating programming.
278 config FEATURE_LESS_FLAGS
279 bool "Enable extra flags"
283 The extra flags provided do the following:
285 The -M flag enables a more sophisticated status line.
286 The -m flag enables a simpler status line with a percentage.

303 config FEATURE_LESS_REGEXP
304 bool "Enable regular expressions"
308 Enable regular expressions, allowing complex file searches.
314 Get/Set hard drive parameters. Primarily intended for ATA
315 drives. Adds about 13k (or around 30k if you enable the
316 FEATURE_HDPARM_GET_IDENTITY option)....
318 config FEATURE_HDPARM_GET_IDENTITY
319 bool "Support obtaining detailed information directly from drives"
323 Enables the -I and -i options to obtain detailed information
324 directly from drives about their capabilities and supported ATA
325 feature set. If no device name is specified, hdparm will read
326 identify data from stdin. Enabling this option will add about 16k...
328 config FEATURE_HDPARM_HDIO_SCAN_HWIF
329 bool "Register an IDE interface (DANGEROUS)"
333 Enables the 'hdparm -R' option to register an IDE interface.
334 This is dangerous stuff, so you should probably say N.
336 config FEATURE_HDPARM_HDIO_UNREGISTER_HWIF
337 bool "Un-register an IDE interface (DANGEROUS)"
341 Enables the 'hdparm -U' option to un-register an IDE interface.
342 This is dangerous stuff, so you should probably say N.
344 config FEATURE_HDPARM_HDIO_DRIVE_RESET
345 bool "Perform device reset (DANGEROUS)"
349 Enables the 'hdparm -w' option to perform a device reset.
350 This is dangerous stuff, so you should probably say N.

353 bool "Tristate device for hotswap (DANGEROUS)"
357 Enables the 'hdparm -x' option to tristate device for hotswap,
358 and the '-b' option to get/set bus state. This is dangerous
359 stuff, so you should probably say N.
361 config FEATURE_HDPARM_HDIO_GETSET_DMA
362 bool "Get/set using_dma flag (DANGEROUS)"
366 Enables the 'hdparm -d' option to get/set using_dma flag.
367 This is dangerous stuff, so you should probably say N.
373 'makedevs' is a utility used to create a batch of devices with
376 There are two choices for command line behaviour, the interface
377 as used by LEAF/Linux Router Project, or a device table file.
379 'leaf' is traditionally what busybox follows, it allows multiple
380 devices of a particluar type to be created per command.
382 Device properties are passed as command line arguments.
384 'table' reads device properties from a file or stdin, allowing
385 a batch of unrelated devices to be made with one command.
386 User/group names are allowed as an alternative to uid/gid.

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