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.
141 config FEATURE_DC_LIBM
142 bool "Enable power and exp functions (requires libm)"
146 Enable power and exp functions.
147 NOTE: This will require libm to be present for linking.
150 bool "devfsd (obsolete)"
152 select FEATURE_SYSLOG
154 This is deprecated, and will be removed at the end of 2008.
156 Provides compatibility with old device names on a devfs systems.
157 You should set it to true if you have devfs enabled.
158 The following keywords in devsfd.conf are supported:
159 "CLEAR_CONFIG", "INCLUDE", "OPTIONAL_INCLUDE", "RESTORE",
160 "PERMISSIONS", "EXECUTE", "COPY", "IGNORE",
161 "MKOLDCOMPAT", "MKNEWCOMPAT","RMOLDCOMPAT", "RMNEWCOMPAT".
163 But only if they are written UPPERCASE!!!!!!!!
165 config DEVFSD_MODLOAD
166 bool "Adds support for MODLOAD keyword in devsfd.conf"
170 This actually doesn't work with busybox modutils but needs
171 the external modutils.
174 bool "Enables the -fg and -np options"
178 -fg Run the daemon in the foreground.
179 -np Exit after parsing the configuration file.
180 Do not poll for events.
182 config DEVFSD_VERBOSE
183 bool "Increases logging (and size)"
187 Increases logging to stderr or syslog.
190 bool "Use devfs names for all devices (obsolete)"
193 This is obsolete and will be going away at the end of 2008..
195 This tells busybox to look for names like /dev/loop/0 instead of
196 /dev/loop0. If your /dev directory has normal names instead of
197 devfs names, you don't want this.
203 Used to eject cdroms. (defaults to /dev/cdrom)
205 config FEATURE_EJECT_SCSI
210 Add the -s option to eject, this allows to eject SCSI-Devices and
217 Shows splash image and progress bar on framebuffer device.
218 Can be used during boot phase of an embedded device. ~2kb.
220 - use kernel option 'vga=xxx' or otherwise enable fb device.
221 - put somewhere fbsplash.cfg file and an image in .ppm format.
222 - $ setsid fbsplash [params] &

262 'last' displays detailed information about the last users that
263 logged into the system (mimics sysvinit last). +900 bytes.
270 'less' is a pager, meaning that it displays text files. It possesses
271 a wide array of features, and is an improvement over 'more'.
273 config FEATURE_LESS_MAXLINES
274 int "Max number of input lines less will try to eat"
278 config FEATURE_LESS_BRACKETS
279 bool "Enable bracket searching"
283 This option adds the capability to search for matching left and right
284 brackets, facilitating programming.

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

361 bool "Tristate device for hotswap (DANGEROUS)"
365 Enables the 'hdparm -x' option to tristate device for hotswap,
366 and the '-b' option to get/set bus state. This is dangerous
367 stuff, so you should probably say N.
369 config FEATURE_HDPARM_HDIO_GETSET_DMA
370 bool "Get/set using_dma flag (DANGEROUS)"
374 Enables the 'hdparm -d' option to get/set using_dma flag.

381 'makedevs' is a utility used to create a batch of devices with
384 There are two choices for command line behaviour, the interface
385 as used by LEAF/Linux Router Project, or a device table file.
387 'leaf' is traditionally what busybox follows, it allows multiple
388 devices of a particluar type to be created per command.
390 Device properties are passed as command line arguments.
392 'table' reads device properties from a file or stdin, allowing
393 a batch of unrelated devices to be made with one command.
394 User/group names are allowed as an alternative to uid/gid.

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