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
197 bool "eject scsi support"
201 Add the -s option to eject, this allows to eject SCSI-Devices and
209 'last' displays a list of the last users that logged into the system.
215 'less' is a pager, meaning that it displays text files. It possesses
216 a wide array of features, and is an improvement over 'more'.
218 config FEATURE_LESS_MAXLINES
219 int "Max number of input lines less will try to eat"
223 config FEATURE_LESS_BRACKETS
224 bool "Enable bracket searching"
228 This option adds the capability to search for matching left and right
229 brackets, facilitating programming.
231 config FEATURE_LESS_FLAGS
232 bool "Enable extra flags"
236 The extra flags provided do the following:
238 The -M flag enables a more sophisticated status line.
239 The -m flag enables a simpler status line with a percentage.
241 config FEATURE_LESS_FLAGCS
242 bool "Enable flag changes"
246 This enables the ability to change command-line flags within
249 config FEATURE_LESS_MARKS
254 Marks enable positions in a file to be stored for easy reference.
256 config FEATURE_LESS_REGEXP
257 bool "Enable regular expressions"
261 Enable regular expressions, allowing complex file searches.
267 Get/Set hard drive parameters. Primarily intended for ATA
268 drives. Adds about 13k (or around 30k if you enable the
269 FEATURE_HDPARM_GET_IDENTITY option)....
271 config FEATURE_HDPARM_GET_IDENTITY
272 bool "Support obtaining detailed information directly from drives"
276 Enables the -I and -i options to obtain detailed information
277 directly from drives about their capabilities and supported ATA
278 feature set. If no device name is specified, hdparm will read
279 identify data from stdin. Enabling this option will add about 16k...
281 config FEATURE_HDPARM_HDIO_SCAN_HWIF
282 bool "Register an IDE interface (DANGEROUS)"
286 Enables the 'hdparm -R' option to register an IDE interface.
287 This is dangerous stuff, so you should probably say N.
289 config FEATURE_HDPARM_HDIO_UNREGISTER_HWIF
290 bool "Un-register an IDE interface (DANGEROUS)"
294 Enables the 'hdparm -U' option to un-register an IDE interface.
295 This is dangerous stuff, so you should probably say N.
297 config FEATURE_HDPARM_HDIO_DRIVE_RESET
298 bool "perform device reset (DANGEROUS)"
302 Enables the 'hdparm -w' option to perform a device reset.
303 This is dangerous stuff, so you should probably say N.
305 config FEATURE_HDPARM_HDIO_TRISTATE_HWIF
306 bool "tristate device for hotswap (DANGEROUS)"
310 Enables the 'hdparm -x' option to tristate device for hotswap,
311 and the '-b' option to get/set bus state. This is dangerous
312 stuff, so you should probably say N.
314 config FEATURE_HDPARM_HDIO_GETSET_DMA
315 bool "get/set using_dma flag (DANGEROUS)"
319 Enables the 'hdparm -d' option to get/set using_dma flag.
320 This is dangerous stuff, so you should probably say N.
326 'makedevs' is a utility used to create a batch of devices with
329 There are two choices for command line behaviour, the interface
330 as used by LEAF/Linux Router Project, or a device table file.
332 'leaf' is traditionally what busybox follows, it allows multiple
333 devices of a particluar type to be created per command.
335 Device properties are passed as command line arguments.
337 'table' reads device properties from a file or stdin, allowing
338 a batch of unrelated devices to be made with one command.
339 User/group names are allowed as an alternative to uid/gid.

358 The poor man's minicom utility for chatting with serial port devices.
364 mountpoint checks if the directory is a mountpoint.
370 mt is used to control tape devices. You can use the mt utility
371 to advance or rewind a tape past a specified number of archive
378 raidautorun tells the kernel md driver to
379 search and start RAID arrays.
386 Preload the files listed on the command line into RAM cache so that
387 subsequent reads on these files will not block on disk I/O.
389 This applet just calls the readahead(2) system call on each file.
390 It is mainly useful in system startup scripts to preload files
391 or executables before they are used. When used at the right time
392 (in particular when a CPU boundprocess is running) it can
393 significantly speed up system startup.
395 As readahead(2) blocks until each file has been read, it is best to
396 run this applet as a background job.
402 find the current and previous system runlevel.
404 This applet uses utmp but does not rely on busybox supporing
405 utmp on purpose. It is used by e.g. emdebian via /etc/init.d/rc.
411 Receive files using the Xmodem protocol.
417 The script makes typescript of terminal session.
423 strings prints the printable character sequences for each file
430 setsid runs a program in a new session
436 Retrieve or set a processes's CPU affinity.
437 This requires sched_{g,s}etaffinity support in your libc.
439 config FEATURE_TASKSET_FANCY
444 Add code for fancy output. This merely silences a compiler-warning
445 and adds about 135 Bytes. May be needed for machines with alot
452 The time command runs the specified program with the given arguments.
453 When the command finishes, time writes a message to standard output
454 giving timing statistics about this program run.
460 A replacement for "stty size". Unlike stty, can report only width,
461 only height, or both, in any order. It also does not complain on error,
462 but returns default 80x24. Usage in shell scripts: width=`ttysize w`.
468 The watchdog utility is used with hardware or software watchdog
469 device drivers. It opens the specified watchdog device special file
470 and periodically writes a magic character to the device. If the
471 watchdog applet ever fails to write the magic character within a
472 certain amount of time, the watchdog device assumes the system has
473 hung, and will cause the hardware to reboot.
