12 Adjtimex reads and optionally sets adjustment parameters for
13 the Linux clock adjustment algorithm.
19 The bbconfig applet will print the config file with which
26 manipulate real-time attributes of a process.
27 This requires sched_{g,s}etparam support in your libc.
35 Crond is a background daemon that parses individual crontab
36 files and executes commands on behalf of the users in question.
37 This is a port of dcron from slackware. It uses files of the
38 format /var/spool/cron/crontabs/<username> files, for example:
39 $ cat /var/spool/cron/crontabs/root
40 # Run daily cron jobs at 4:40 every day:
41 40 4 * * * /etc/cron/daily > /dev/null 2>&1
42 Note that Busybox binary must be setuid root for this applet to
45 config DEBUG_CROND_OPTION
46 bool "Support debug option -d"
50 Support option -d to enter debug mode.
52 config FEATURE_CROND_CALL_SENDMAIL
53 bool "Using /usr/sbin/sendmail?"
57 Support calling /usr/sbin/sendmail for send cmd outputs.
64 Crontab manipulates the crontab for a particular user. Only
65 the superuser may specify a different user and/or crontab directory.
71 Dc is a reverse-polish desk calculator which supports unlimited
75 bool "devfsd (obsolete)"
79 This is deprecated, and will be removed at the end of 2008.
81 Provides compatibility with old device names on a devfs systems.
82 You should set it to true if you have devfs enabled.
83 The following keywords in devsfd.conf are supported:
84 "CLEAR_CONFIG", "INCLUDE", "OPTIONAL_INCLUDE", "RESTORE",
85 "PERMISSIONS", "EXECUTE", "COPY", "IGNORE",
86 "MKOLDCOMPAT", "MKNEWCOMPAT","RMOLDCOMPAT", "RMNEWCOMPAT".
88 But only if they are written UPPERCASE!!!!!!!!
91 bool "Adds support for MODLOAD keyword in devsfd.conf"
95 This actually doesn't work with busybox modutils but needs
96 the external modutils.
99 bool "Enables the -fg and -np options"
103 -fg Run the daemon in the foreground.
104 -np Exit after parsing the configuration file. Do not poll for events.
106 config DEVFSD_VERBOSE
107 bool "Increases logging (and size)"
111 Increases logging to stderr or syslog.
114 bool " Use devfs names for all devices (obsolete)"
117 This is obsolete and will be going away at the end of 2008..
119 This tells busybox to look for names like /dev/loop/0 instead of
120 /dev/loop0. If your /dev directory has normal names instead of
121 devfs names, you don't want this.
127 Used to eject cdroms. (defaults to /dev/cdrom)
129 config FEATURE_EJECT_SCSI
130 bool "eject scsi support"
134 Add the -s option to eject, this allows to eject SCSI-Devices and
142 'last' displays a list of the last users that logged into the system.
148 'less' is a pager, meaning that it displays text files. It possesses
149 a wide array of features, and is an improvement over 'more'.
151 config FEATURE_LESS_MAXLINES
152 int "Max number of input lines less will try to eat"
156 config FEATURE_LESS_BRACKETS
157 bool "Enable bracket searching"
161 This option adds the capability to search for matching left and right
162 brackets, facilitating programming.
164 config FEATURE_LESS_FLAGS
165 bool "Enable extra flags"
169 The extra flags provided do the following:
171 The -M flag enables a more sophisticated status line.
172 The -m flag enables a simpler status line with a percentage.
174 config FEATURE_LESS_FLAGCS
175 bool "Enable flag changes"
179 This enables the ability to change command-line flags within
182 config FEATURE_LESS_MARKS
187 Marks enable positions in a file to be stored for easy reference.
189 config FEATURE_LESS_REGEXP
190 bool "Enable regular expressions"
194 Enable regular expressions, allowing complex file searches.
200 Get/Set hard drive parameters. Primarily intended for ATA
201 drives. Adds about 13k (or around 30k if you enable the
202 FEATURE_HDPARM_GET_IDENTITY option)....
204 config FEATURE_HDPARM_GET_IDENTITY
205 bool "Support obtaining detailed information directly from drives"
209 Enables the -I and -i options to obtain detailed information
210 directly from drives about their capabilities and supported ATA
211 feature set. If no device name is specified, hdparm will read
212 identify data from stdin. Enabling this option will add about 16k...
214 config FEATURE_HDPARM_HDIO_SCAN_HWIF
215 bool "Register an IDE interface (DANGEROUS)"
219 Enables the 'hdparm -R' option to register an IDE interface.
220 This is dangerous stuff, so you should probably say N.
222 config FEATURE_HDPARM_HDIO_UNREGISTER_HWIF
223 bool "Un-register an IDE interface (DANGEROUS)"
227 Enables the 'hdparm -U' option to un-register an IDE interface.
228 This is dangerous stuff, so you should probably say N.
230 config FEATURE_HDPARM_HDIO_DRIVE_RESET
231 bool "perform device reset (DANGEROUS)"
235 Enables the 'hdparm -w' option to perform a device reset.
236 This is dangerous stuff, so you should probably say N.
238 config FEATURE_HDPARM_HDIO_TRISTATE_HWIF
239 bool "tristate device for hotswap (DANGEROUS)"
243 Enables the 'hdparm -x' option to tristate device for hotswap,
244 and the '-b' option to get/set bus state. This is dangerous
245 stuff, so you should probably say N.
247 config FEATURE_HDPARM_HDIO_GETSET_DMA
248 bool "get/set using_dma flag (DANGEROUS)"
252 Enables the 'hdparm -d' option to get/set using_dma flag.
253 This is dangerous stuff, so you should probably say N.
259 'makedevs' is a utility used to create a batch of devices with
262 There are two choices for command line behaviour, the interface
263 as used by LEAF/Linux Router Project, or a device table file.
265 'leaf' is traditionally what busybox follows, it allows multiple
266 devices of a particluar type to be created per command.
268 Device properties are passed as command line arguments.
270 'table' reads device properties from a file or stdin, allowing
271 a batch of unrelated devices to be made with one command.
272 User/group names are allowed as an alternative to uid/gid.
275 prompt "Choose makedevs behaviour"

291 The poor man's minicom utility for chatting with serial port devices.
297 mountpoint checks if the directory is a mountpoint.
303 mt is used to control tape devices. You can use the mt utility
304 to advance or rewind a tape past a specified number of archive
311 raidautorun tells the kernel md driver to
312 search and start RAID arrays.
319 Preload the files listed on the command line into RAM cache so that
320 subsequent reads on these files will not block on disk I/O.
322 This applet just calls the readahead(2) system call on each file.
323 It is mainly useful in system startup scripts to preload files
324 or executables before they are used. When used at the right time
325 (in particular when a CPU boundprocess is running) it can
326 significantly speed up system startup.
328 As readahead(2) blocks until each file has been read, it is best to
329 run this applet as a background job.
335 find the current and previous system runlevel.
337 This applet uses utmp but does not rely on busybox supporing
338 utmp on purpose. It is used by e.g. emdebian via /etc/init.d/rc.
344 Receive files using the Xmodem protocol.
350 strings prints the printable character sequences for each file
357 setsid runs a program in a new session
363 Retrieve or set a processes's CPU affinity.
364 This requires sched_{g,s}etaffinity support in your libc.
366 config FEATURE_TASKSET_FANCY
371 Add code for fancy output. This merely silences a compiler-warning
372 and adds about 135 Bytes. May be needed for machines with alot
379 The time command runs the specified program with the given arguments.
380 When the command finishes, time writes a message to standard output
381 giving timing statistics about this program run.
387 A replacement for "stty size". Unlike stty, can report only width,
388 only height, or both, in any order. It also does not complain on error,
389 but returns default 80x24. Usage in shell scripts: width=`ttysize w`.
395 The watchdog utility is used with hardware or software watchdog
396 device drivers. It opens the specified watchdog device special file
397 and periodically writes a magic character to the device. If the
398 watchdog applet ever fails to write the magic character within a
399 certain amount of time, the watchdog device assumes the system has
400 hung, and will cause the hardware to reboot.
