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110 This is obsolete and will be going away at the end of 2008..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_MAXLINES
137 int "Max number of input lines less will try to eat"
141 config FEATURE_LESS_BRACKETS
142 bool "Enable bracket searching"
146 This option adds the capability to search for matching left and right
147 brackets, facilitating programming.
149 config FEATURE_LESS_FLAGS
150 bool "Enable extra flags"
154 The extra flags provided do the following:
156 The -M flag enables a more sophisticated status line.
157 The -m flag enables a simpler status line with a percentage.
159 config FEATURE_LESS_FLAGCS
160 bool "Enable flag changes"
164 This enables the ability to change command-line flags within
167 config FEATURE_LESS_MARKS
172 Marks enable positions in a file to be stored for easy reference.
174 config FEATURE_LESS_REGEXP
175 bool "Enable regular expressions"
179 Enable regular expressions, allowing complex file searches.
185 Get/Set hard drive parameters. Primarily intended for ATA
186 drives. Adds about 13k (or around 30k if you enable the
187 FEATURE_HDPARM_GET_IDENTITY option)....
189 config FEATURE_HDPARM_GET_IDENTITY
190 bool "Support obtaining detailed information directly from drives"
194 Enables the -I and -i options to obtain detailed information
195 directly from drives about their capabilities and supported ATA
196 feature set. If no device name is specified, hdparm will read
197 identify data from stdin. Enabling this option will add about 16k...
199 config FEATURE_HDPARM_HDIO_SCAN_HWIF
200 bool "Register an IDE interface (DANGEROUS)"
204 Enables the 'hdparm -R' option to register an IDE interface.
205 This is dangerous stuff, so you should probably say N.
207 config FEATURE_HDPARM_HDIO_UNREGISTER_HWIF
208 bool "Un-register an IDE interface (DANGEROUS)"
212 Enables the 'hdparm -U' option to un-register an IDE interface.
213 This is dangerous stuff, so you should probably say N.
215 config FEATURE_HDPARM_HDIO_DRIVE_RESET
216 bool "perform device reset (DANGEROUS)"
220 Enables the 'hdparm -w' option to perform a device reset.
221 This is dangerous stuff, so you should probably say N.
223 config FEATURE_HDPARM_HDIO_TRISTATE_HWIF
224 bool "tristate device for hotswap (DANGEROUS)"
228 Enables the 'hdparm -x' option to tristate device for hotswap,
229 and the '-b' option to get/set bus state. This is dangerous
230 stuff, so you should probably say N.
232 config FEATURE_HDPARM_HDIO_GETSET_DMA
233 bool "get/set using_dma flag (DANGEROUS)"
237 Enables the 'hdparm -d' option to get/set using_dma flag.
238 This is dangerous stuff, so you should probably say N.
244 'makedevs' is a utility used to create a batch of devices with
247 There are two choices for command line behaviour, the interface
248 as used by LEAF/Linux Router Project, or a device table file.
250 'leaf' is traditionally what busybox follows, it allows multiple
251 devices of a particluar type to be created per command.
253 Device properties are passed as command line arguments.
255 'table' reads device properties from a file or stdin, allowing
256 a batch of unrelated devices to be made with one command.
257 User/group names are allowed as an alternative to uid/gid.
260 prompt "Choose makedevs behaviour"
262 default FEATURE_MAKEDEVS_TABLE
264 config FEATURE_MAKEDEVS_LEAF
267 config FEATURE_MAKEDEVS_TABLE
276 mountpoint checks if the directory is a mountpoint.
282 mt is used to control tape devices. You can use the mt utility
283 to advance or rewind a tape past a specified number of archive
290 nmeter prints various system parameters continuously.
296 raidautorun tells the kernel md driver to
297 search and start RAID arrays.
304 Preload the files listed on the command line into RAM cache so that
305 subsequent reads on these files will not block on disk I/O.
307 This applet just calls the readahead(2) system call on each file.
308 It is mainly useful in system startup scripts to preload files
309 or executables before they are used. When used at the right time
310 (in particular when a CPU boundprocess is running) it can
311 significantly speed up system startup.
313 As readahead(2) blocks until each file has been read, it is best to
314 run this applet as a background job.
320 find the current and previous system runlevel.
322 This applet uses utmp but does not rely on busybox supporing
323 utmp on purpose. It is used by e.g. emdebian via /etc/init.d/rc.
329 Receive files using the Xmodem protocol.
335 strings prints the printable character sequences for each file
342 setsid runs a program in a new session
348 Retrieve or set a processes's CPU affinity.
349 This requires sched_{g,s}etaffinity support in your libc.
351 config FEATURE_TASKSET_FANCY
356 Add code for fancy output. This merely silences a compiler-warning
357 and adds about 135 Bytes. May be needed for machines with alot
364 The time command runs the specified program with the given arguments.
365 When the command finishes, time writes a message to standard output
366 giving timing statistics about this program run.
372 The watchdog utility is used with hardware or software watchdog
373 device drivers. It opens the specified watchdog device special file
374 and periodically writes a magic character to the device. If the
375 watchdog applet ever fails to write the magic character within a
376 certain amount of time, the watchdog device assumes the system has
377 hung, and will cause the hardware to reboot.
