29 int "default frequency"
34 Frequency for default beep.
36 config FEATURE_BEEP_LENGTH_MS
42 Length in ms for default beep.
50 config FEATURE_CHAT_NOFAIL
51 bool "Enable NOFAIL expect strings"
55 When enabled expect strings which are started with a dash trigger
56 no-fail mode. That is when expectation is not met within timeout
57 the script is not terminated but sends next SEND string and waits
58 for next EXPECT string. This allows to compose far more flexible
61 config FEATURE_CHAT_TTY_HIFI
62 bool "Force STDIN to be a TTY"
66 Original chat always treats STDIN as a TTY device and sets for it
67 so-called raw mode. This option turns on such behaviour.
69 config FEATURE_CHAT_IMPLICIT_CR
70 bool "Enable implicit Carriage Return"
74 When enabled make chat to terminate all SEND strings with a "\r"
75 unless "\c" is met anywhere in the string.
77 config FEATURE_CHAT_SWALLOW_OPTS
78 bool "Swallow options"
82 Busybox chat require no options. To make it not fail when used
83 in place of original chat (which has a bunch of options) turn
86 config FEATURE_CHAT_SEND_ESCAPES
87 bool "Support weird SEND escapes"
91 Original chat uses some escape sequences in SEND arguments which
92 are not sent to device but rather performs special actions.
93 E.g. "\K" means to send a break sequence to device.
94 "\d" delays execution for a second, "\p" -- for a 1/100 of second.
95 Before turning this option on think twice: do you really need them?
97 config FEATURE_CHAT_VAR_ABORT_LEN
98 bool "Support variable-length ABORT conditions"
102 Original chat uses fixed 50-bytes length ABORT conditions. Say N here.
104 config FEATURE_CHAT_CLR_ABORT
105 bool "Support revoking of ABORT conditions"
109 Support CLR_ABORT directive.

124 Crond is a background daemon that parses individual crontab
125 files and executes commands on behalf of the users in question.
126 This is a port of dcron from slackware. It uses files of the
127 format /var/spool/cron/crontabs/<username> files, for example:
128 $ cat /var/spool/cron/crontabs/root
129 # Run daily cron jobs at 4:40 every day:
130 40 4 * * * /etc/cron/daily > /dev/null 2>&1
132 config FEATURE_CROND_D

140 bool "Using /usr/sbin/sendmail?"
144 Support calling /usr/sbin/sendmail for send cmd outputs.
146 config FEATURE_CROND_DIR
147 string "crond spool directory"
148 default "/var/spool/cron"
149 depends on CROND || CRONTAB
151 Location of crond spool.

175 Enable power and exp functions.
176 NOTE: This will require libm to be present for linking.
179 bool "devfsd (obsolete)"
181 select FEATURE_SYSLOG
183 This is deprecated and should NOT be used anymore.
184 Use linux >= 2.6 (optionally with hotplug) and mdev instead!
185 See docs/mdev.txt for detailed instructions on how to use mdev
188 Provides compatibility with old device names on a devfs systems.
189 You should set it to true if you have devfs enabled.
190 The following keywords in devsfd.conf are supported:
191 "CLEAR_CONFIG", "INCLUDE", "OPTIONAL_INCLUDE", "RESTORE",
192 "PERMISSIONS", "EXECUTE", "COPY", "IGNORE",

197 config DEVFSD_MODLOAD
198 bool "Adds support for MODLOAD keyword in devsfd.conf"
202 This actually doesn't work with busybox modutils but needs
203 the external modutils.

210 -fg Run the daemon in the foreground.
211 -np Exit after parsing the configuration file.
212 Do not poll for events.

215 bool "Increases logging (and size)"
219 Increases logging to stderr or syslog.
222 bool "Use devfs names for all devices (obsolete)"
225 This is obsolete and should NOT be used anymore.
226 Use linux >= 2.6 (optionally with hotplug) and mdev instead!
228 For legacy systems -- if there is no way around devfsd -- this
229 tells busybox to look for names like /dev/loop/0 instead of
230 /dev/loop0. If your /dev directory has normal names instead of
231 devfs names, you don't want this.
237 devmem is a small program that reads and writes from physical
238 memory using /dev/mem.

332 logged into the system (mimics sysvinit last). +900 bytes.

407 FEATURE_HDPARM_GET_IDENTITY option)....
409 config FEATURE_HDPARM_GET_IDENTITY
410 bool "Support obtaining detailed information directly from drives"
414 Enables the -I and -i options to obtain detailed information
415 directly from drives about their capabilities and supported ATA
416 feature set. If no device name is specified, hdparm will read
417 identify data from stdin. Enabling this option will add about 16k...
419 config FEATURE_HDPARM_HDIO_SCAN_HWIF
420 bool "Register an IDE interface (DANGEROUS)"
424 Enables the 'hdparm -R' option to register an IDE interface.

427 config FEATURE_HDPARM_HDIO_UNREGISTER_HWIF
428 bool "Un-register an IDE interface (DANGEROUS)"
432 Enables the 'hdparm -U' option to un-register an IDE interface.

466 There are two choices for command line behaviour, the interface
467 as used by LEAF/Linux Router Project, or a device table file.
469 'leaf' is traditionally what busybox follows, it allows multiple
470 devices of a particluar type to be created per command.
472 Device properties are passed as command line arguments.
474 'table' reads device properties from a file or stdin, allowing
475 a batch of unrelated devices to be made with one command.
476 User/group names are allowed as an alternative to uid/gid.

514 to advance or rewind a tape past a specified number of archive
521 raidautorun tells the kernel md driver to
522 search and start RAID arrays.
529 Preload the files listed on the command line into RAM cache so that
530 subsequent reads on these files will not block on disk I/O.
532 This applet just calls the readahead(2) system call on each file.
533 It is mainly useful in system startup scripts to preload files
534 or executables before they are used. When used at the right time
535 (in particular when a CPU bound process is running) it can
536 significantly speed up system startup.
538 As readahead(2) blocks until each file has been read, it is best to
539 run this applet as a background job.
545 find the current and previous system runlevel.
547 This applet uses utmp but does not rely on busybox supporing
548 utmp on purpose. It is used by e.g. emdebian via /etc/init.d/rc.

589 The time command runs the specified program with the given arguments.
590 When the command finishes, time writes a message to standard output
591 giving timing statistics about this program run.
597 Runs a program and watches it. If it does not terminate in
598 specified number of seconds, it is sent a signal.
604 A replacement for "stty size". Unlike stty, can report only width,
605 only height, or both, in any order. It also does not complain on
606 error, but returns default 80x24.
607 Usage in shell scripts: width=`ttysize w`.
613 Prints a CD-ROM volume name.
619 The watchdog utility is used with hardware or software watchdog
620 device drivers. It opens the specified watchdog device special file
621 and periodically writes a magic character to the device. If the
622 watchdog applet ever fails to write the magic character within a
623 certain amount of time, the watchdog device assumes the system has
624 hung, and will cause the hardware to reboot.
