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
28 Crond is a background daemon that parses individual crontab
29 files and executes commands on behalf of the users in question.
30 This is a port of dcron from slackware. It uses files of the
31 format /var/spool/cron/crontabs/<username> files, for example:
32 $ cat /var/spool/cron/crontabs/root
33 # Run daily cron jobs at 4:40 every day:
34 40 4 * * * /etc/cron/daily > /dev/null 2>&1
35 Note that Busybox binary must be setuid root for this applet to
38 config DEBUG_CROND_OPTION
39 bool "Support debug option -d"
43 Support option -d to enter debug mode.
45 config FEATURE_CROND_CALL_SENDMAIL
46 bool "Using /usr/sbin/sendmail?"
50 Support calling /usr/sbin/sendmail for send cmd outputs.
57 Crontab manipulates the crontab for a particular user. Only
58 the superuser may specify a different user and/or crontab directory.
64 Dc is a reverse-polish desk calculator which supports unlimited
68 bool "devfsd (obsolete)"
72 This is deprecated, and will be removed at the end of 2008.
74 Provides compatibility with old device names on a devfs systems.
75 You should set it to true if you have devfs enabled.
76 The following keywords in devsfd.conf are supported:
77 "CLEAR_CONFIG", "INCLUDE", "OPTIONAL_INCLUDE", "RESTORE",
78 "PERMISSIONS", "EXECUTE", "COPY", "IGNORE",
79 "MKOLDCOMPAT", "MKNEWCOMPAT","RMOLDCOMPAT", "RMNEWCOMPAT".
81 But only if they are written UPPERCASE!!!!!!!!
84 bool "Adds support for MODLOAD keyword in devsfd.conf"
88 This actually doesn't work with busybox modutils but needs
89 the external modutils.
92 bool "Enables the -fg and -np options"
96 -fg Run the daemon in the foreground.
97 -np Exit after parsing the configuration file. Do not poll for events.
100 bool "Increases logging (and size)"
104 Increases logging to stderr or syslog.
107 bool " Use devfs names for all devices (obsolete)"
110 This is obsolete and will be going away at the end of 2008..
112 This tells busybox to look for names like /dev/loop/0 instead of
113 /dev/loop0. If your /dev directory has normal names instead of
114 devfs names, you don't want this.
120 Used to eject cdroms. (defaults to /dev/cdrom)
127 'last' displays a list of the last users that logged into the system.
133 'less' is a pager, meaning that it displays text files. It possesses
134 a wide array of features, and is an improvement over 'more'.
136 config FEATURE_LESS_BRACKETS
137 bool "Enable bracket searching"
141 This option adds the capability to search for matching left and right
142 brackets, facilitating programming.
144 config FEATURE_LESS_FLAGS
145 bool "Enable extra flags"
149 The extra flags provided do the following:
151 The -M flag enables a more sophisticated status line.
152 The -m flag enables a simpler status line with a percentage.
154 config FEATURE_LESS_FLAGCS
155 bool "Enable flag changes"
159 This enables the ability to change command-line flags within
162 config FEATURE_LESS_MARKS
167 Marks enable positions in a file to be stored for easy reference.
169 config FEATURE_LESS_REGEXP
170 bool "Enable regular expressions"
174 Enable regular expressions, allowing complex file searches.
180 Get/Set hard drive parameters. Primarily intended for ATA
181 drives. Adds about 13k (or around 30k if you enable the
182 FEATURE_HDPARM_GET_IDENTITY option)....
184 config FEATURE_HDPARM_GET_IDENTITY
185 bool "Support obtaining detailed information directly from drives"
189 Enables the -I and -i options to obtain detailed information
190 directly from drives about their capabilities and supported ATA
191 feature set. If no device name is specified, hdparm will read
192 identify data from stdin. Enabling this option will add about 16k...
194 config FEATURE_HDPARM_HDIO_SCAN_HWIF
195 bool "Register an IDE interface (DANGEROUS)"
199 Enables the 'hdparm -R' option to register an IDE interface.
200 This is dangerous stuff, so you should probably say N.
202 config FEATURE_HDPARM_HDIO_UNREGISTER_HWIF
203 bool "Un-register an IDE interface (DANGEROUS)"
207 Enables the 'hdparm -U' option to un-register an IDE interface.
208 This is dangerous stuff, so you should probably say N.
210 config FEATURE_HDPARM_HDIO_DRIVE_RESET
211 bool "perform device reset (DANGEROUS)"
215 Enables the 'hdparm -w' option to perform a device reset.
216 This is dangerous stuff, so you should probably say N.
218 config FEATURE_HDPARM_HDIO_TRISTATE_HWIF
219 bool "tristate device for hotswap (DANGEROUS)"
223 Enables the 'hdparm -x' option to tristate device for hotswap,
224 and the '-b' option to get/set bus state. This is dangerous
225 stuff, so you should probably say N.
227 config FEATURE_HDPARM_HDIO_GETSET_DMA
228 bool "get/set using_dma flag (DANGEROUS)"
232 Enables the 'hdparm -d' option to get/set using_dma flag.
233 This is dangerous stuff, so you should probably say N.
239 'makedevs' is a utility used to create a batch of devices with
242 There are two choices for command line behaviour, the interface
243 as used by LEAF/Linux Router Project, or a device table file.
245 'leaf' is traditionally what busybox follows, it allows multiple
246 devices of a particluar type to be created per command.
248 Device properties are passed as command line arguments.
250 'table' reads device properties from a file or stdin, allowing
251 a batch of unrelated devices to be made with one command.
252 User/group names are allowed as an alternative to uid/gid.
255 prompt "Choose makedevs behaviour"
257 default FEATURE_MAKEDEVS_TABLE

271 mountpoint checks if the directory is a mountpoint.
277 mt is used to control tape devices. You can use the mt utility
278 to advance or rewind a tape past a specified number of archive
285 nmeter prints various system parameters continuously.
291 raidautorun tells the kernel md driver to
292 search and start RAID arrays.
298 Preload the files listed on the command line into RAM cache so that
299 subsequent reads on these files will not block on disk I/O.
301 This applet just calls the readahead(2) system call on each file.
302 It is mainly useful in system startup scripts to preload files
303 or executables before they are used. When used at the right time
304 (in particular when a CPU boundprocess is running) it can
305 significantly speed up system startup.
307 As readahead(2) blocks until each file has been read, it is best to
308 run this applet as a background job.
314 find the current and previous system runlevel.
316 This applet uses utmp but does not rely on busybox supporing
317 utmp on purpose. It is used by e.g. emdebian via /etc/init.d/rc.
323 Receive files using the Xmodem protocol.
329 strings prints the printable character sequences for each file
336 setsid runs a program in a new session
342 Retrieve or set a processes's CPU affinity.
343 This requires sched_{g,s}etaffinity support in your libc.
345 config FEATURE_TASKSET_FANCY
350 Add code for fancy output. This merely silences a compiler-warning
351 and adds about 135 Bytes. May be needed for machines with alot
358 The time command runs the specified program with the given arguments.
359 When the command finishes, time writes a message to standard output
360 giving timing statistics about this program run.
366 The watchdog utility is used with hardware or software watchdog
367 device drivers. It opens the specified watchdog device special file
368 and periodically writes a magic character to the device. If the
369 watchdog applet ever fails to write the magic character within a
370 certain amount of time, the watchdog device assumes the system has
371 hung, and will cause the hardware to reboot.
