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)
218 -f path_to_fifo (can be "-" for stdin)
219 - if you want to run it only in presence of kernel parameter:
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.
232 config FEATURE_LAST_FANCY
237 'last' displays detailed information about the last users that
238 logged into the system (mimics sysvinit last). +900 bytes.
244 'less' is a pager, meaning that it displays text files. It possesses
245 a wide array of features, and is an improvement over 'more'.
247 config FEATURE_LESS_MAXLINES
248 int "Max number of input lines less will try to eat"
252 config FEATURE_LESS_BRACKETS
253 bool "Enable bracket searching"
257 This option adds the capability to search for matching left and right
258 brackets, facilitating programming.
260 config FEATURE_LESS_FLAGS
261 bool "Enable extra flags"
265 The extra flags provided do the following:
267 The -M flag enables a more sophisticated status line.
268 The -m flag enables a simpler status line with a percentage.
270 config FEATURE_LESS_FLAGCS
271 bool "Enable flag changes"
275 This enables the ability to change command-line flags within

285 config FEATURE_LESS_REGEXP
286 bool "Enable regular expressions"
290 Enable regular expressions, allowing complex file searches.
296 Get/Set hard drive parameters. Primarily intended for ATA
297 drives. Adds about 13k (or around 30k if you enable the
298 FEATURE_HDPARM_GET_IDENTITY option)....
300 config FEATURE_HDPARM_GET_IDENTITY
301 bool "Support obtaining detailed information directly from drives"
305 Enables the -I and -i options to obtain detailed information
306 directly from drives about their capabilities and supported ATA
307 feature set. If no device name is specified, hdparm will read
308 identify data from stdin. Enabling this option will add about 16k...
310 config FEATURE_HDPARM_HDIO_SCAN_HWIF
311 bool "Register an IDE interface (DANGEROUS)"
315 Enables the 'hdparm -R' option to register an IDE interface.
316 This is dangerous stuff, so you should probably say N.
318 config FEATURE_HDPARM_HDIO_UNREGISTER_HWIF
319 bool "Un-register an IDE interface (DANGEROUS)"
323 Enables the 'hdparm -U' option to un-register an IDE interface.
324 This is dangerous stuff, so you should probably say N.
326 config FEATURE_HDPARM_HDIO_DRIVE_RESET
327 bool "perform device reset (DANGEROUS)"
331 Enables the 'hdparm -w' option to perform a device reset.
332 This is dangerous stuff, so you should probably say N.
334 config FEATURE_HDPARM_HDIO_TRISTATE_HWIF
335 bool "tristate device for hotswap (DANGEROUS)"
339 Enables the 'hdparm -x' option to tristate device for hotswap,
340 and the '-b' option to get/set bus state. This is dangerous
341 stuff, so you should probably say N.
343 config FEATURE_HDPARM_HDIO_GETSET_DMA
344 bool "get/set using_dma flag (DANGEROUS)"
348 Enables the 'hdparm -d' option to get/set using_dma flag.
349 This is dangerous stuff, so you should probably say N.
355 'makedevs' is a utility used to create a batch of devices with
358 There are two choices for command line behaviour, the interface
359 as used by LEAF/Linux Router Project, or a device table file.
361 'leaf' is traditionally what busybox follows, it allows multiple
362 devices of a particluar type to be created per command.
364 Device properties are passed as command line arguments.
366 'table' reads device properties from a file or stdin, allowing
367 a batch of unrelated devices to be made with one command.
368 User/group names are allowed as an alternative to uid/gid.

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