22 config BUSYBOX_CONFIG_CHAT
28 config BUSYBOX_CONFIG_FEATURE_CHAT_NOFAIL
29 bool "Enable NOFAIL expect strings"
30 depends on BUSYBOX_CONFIG_CHAT
33 When enabled expect strings which are started with a dash trigger
34 no-fail mode. That is when expectation is not met within timeout
35 the script is not terminated but sends next SEND string and waits
36 for next EXPECT string. This allows to compose far more flexible
39 config BUSYBOX_CONFIG_FEATURE_CHAT_TTY_HIFI
40 bool "Force STDIN to be a TTY"
41 depends on BUSYBOX_CONFIG_CHAT
44 Original chat always treats STDIN as a TTY device and sets for it
45 so-called raw mode. This option turns on such behaviour.
47 config BUSYBOX_CONFIG_FEATURE_CHAT_IMPLICIT_CR
48 bool "Enable implicit Carriage Return"
49 depends on BUSYBOX_CONFIG_CHAT

64 config BUSYBOX_CONFIG_FEATURE_CHAT_SEND_ESCAPES
65 bool "Support weird SEND escapes"
66 depends on BUSYBOX_CONFIG_CHAT
69 Original chat uses some escape sequences in SEND arguments which
70 are not sent to device but rather performs special actions.
71 E.g. "\K" means to send a break sequence to device.
72 "\d" delays execution for a second, "\p" -- for a 1/100 of second.
73 Before turning this option on think twice: do you really need them?
75 config BUSYBOX_CONFIG_FEATURE_CHAT_VAR_ABORT_LEN
76 bool "Support variable-length ABORT conditions"

100 select BUSYBOX_CONFIG_FEATURE_SYSLOG
102 Crond is a background daemon that parses individual crontab
103 files and executes commands on behalf of the users in question.
104 This is a port of dcron from slackware. It uses files of the
105 format /var/spool/cron/crontabs/<username> files, for example:
106 $ cat /var/spool/cron/crontabs/root

166 Provides compatibility with old device names on a devfs systems.
167 You should set it to true if you have devfs enabled.
168 The following keywords in devsfd.conf are supported:

170 "PERMISSIONS", "EXECUTE", "COPY", "IGNORE",

204 Use linux >= 2.6 (optionally with hotplug) and mdev instead!
206 For legacy systems -- if there is no way around devfsd -- this
207 tells busybox to look for names like /dev/loop/0 instead of
208 /dev/loop0. If your /dev directory has normal names instead of
209 devfs names, you don't want this.

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

494 config BUSYBOX_CONFIG_READAHEAD
497 depends on BUSYBOX_CONFIG_LFS
499 Preload the files listed on the command line into RAM cache so that
500 subsequent reads on these files will not block on disk I/O.
502 This applet just calls the readahead(2) system call on each file.
503 It is mainly useful in system startup scripts to preload files
504 or executables before they are used. When used at the right time
505 (in particular when a CPU bound process is running) it can
506 significantly speed up system startup.
508 As readahead(2) blocks until each file has been read, it is best to
509 run this applet as a background job.
511 config BUSYBOX_CONFIG_RUNLEVEL
515 find the current and previous system runlevel.
517 This applet uses utmp but does not rely on busybox supporing
518 utmp on purpose. It is used by e.g. emdebian via /etc/init.d/rc.
520 config BUSYBOX_CONFIG_RX
524 Receive files using the Xmodem protocol.
526 config BUSYBOX_CONFIG_SETSID

560 When the command finishes, time writes a message to standard output
561 giving timing statistics about this program run.
563 config BUSYBOX_CONFIG_TIMEOUT
567 Runs a program and watches it. If it does not terminate in
568 specified number of seconds, it is sent a signal.
570 config BUSYBOX_CONFIG_TTYSIZE
574 A replacement for "stty size". Unlike stty, can report only width,
575 only height, or both, in any order. It also does not complain on
576 error, but returns default 80x24.
577 Usage in shell scripts: width=`ttysize w`.
579 config BUSYBOX_CONFIG_WATCHDOG
583 The watchdog utility is used with hardware or software watchdog
584 device drivers. It opens the specified watchdog device special file
585 and periodically writes a magic character to the device. If the
586 watchdog applet ever fails to write the magic character within a
587 certain amount of time, the watchdog device assumes the system has
588 hung, and will cause the hardware to reboot.
