27 Crond is a background daemon that parses individual crontab
28 files and executes commands on behalf of the users in question.
29 This is a port of dcron from slackware. It uses files of the
30 format /var/spool/cron/crontabs/<username> files, for example:
31 $ cat /var/spool/cron/crontabs/root
32 # Run daily cron jobs at 4:40 every day:

169 config CONFIG_FEATURE_HDPARM_GET_IDENTITY
170 bool "Support obtaining detailed information directly from drives"
172 depends on CONFIG_HDPARM
174 Enables the -I and -i options to obtain detailed information
175 directly from drives about their capabilities and supported ATA
176 feature set. If no device name is specified, hdparm will read
177 identify data from stdin. Enabling this option will add about 16k...
179 config CONFIG_FEATURE_HDPARM_HDIO_SCAN_HWIF
180 bool "Register an IDE interface (DANGEROUS)"
182 depends on CONFIG_HDPARM
184 Enables the 'hdparm -R' option to register an IDE interface.
185 This is dangerous stuff, so you should probably say N.
187 config CONFIG_FEATURE_HDPARM_HDIO_UNREGISTER_HWIF
188 bool "Un-register an IDE interface (DANGEROUS)"
190 depends on CONFIG_HDPARM
192 Enables the 'hdparm -U' option to un-register an IDE interface.
193 This is dangerous stuff, so you should probably say N.
195 config CONFIG_FEATURE_HDPARM_HDIO_DRIVE_RESET
196 bool "perform device reset (DANGEROUS)"
198 depends on CONFIG_HDPARM
200 Enables the 'hdparm -w' option to perform a device reset.

215 depends on CONFIG_HDPARM
217 Enables the 'hdparm -d' option to get/set using_dma flag.

220 config CONFIG_MAKEDEVS
224 'makedevs' is a utility used to create a batch of devices with
227 There are two choices for command line behaviour, the interface
228 as used by LEAF/Linux Router Project, or a device table file.
230 'leaf' is traditionally what busybox follows, it allows multiple
231 devices of a particluar type to be created per command.
233 Device properties are passed as command line arguments.
235 'table' reads device properties from a file or stdin, allowing
236 a batch of unrelated devices to be made with one command.
237 User/group names are allowed as an alternative to uid/gid.

256 mountpoint checks if the directory is a mountpoint.
262 mt is used to control tape devices. You can use the mt utility
263 to advance or rewind a tape past a specified number of archive
266 config CONFIG_RUNLEVEL
270 find the current and previous system runlevel.
272 This applet uses utmp but does not rely on busybox supporing
273 utmp on purpose. It is used by e.g. emdebian via /etc/init.d/rc.
279 Receive files using the Xmodem protocol.
281 config CONFIG_STRINGS
285 strings prints the printable character sequences for each file
292 setsid runs a program in a new session
298 The time command runs the specified program with the given arguments.
299 When the command finishes, time writes a message to standard output
300 giving timing statistics about this program run.
302 config CONFIG_WATCHDOG
306 The watchdog utility is used with hardware or software watchdog
307 device drivers. It opens the specified watchdog device special file
308 and periodically writes a magic character to the device. If the
309 watchdog applet ever fails to write the magic character within a
310 certain amount of time, the watchdog device assumes the system has
311 hung, and will cause the hardware to reboot.
