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
52 When enabled make chat to terminate all SEND strings with a "\r"
53 unless "\c" is met anywhere in the string.
55 config BUSYBOX_CONFIG_FEATURE_CHAT_SWALLOW_OPTS
56 bool "Swallow options"
57 depends on BUSYBOX_CONFIG_CHAT
60 Busybox chat require no options. To make it not fail when used
61 in place of original chat (which has a bunch of options) turn
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"

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
107 # Run daily cron jobs at 4:40 every day:

178 Increases logging to stderr or syslog.
180 config BUSYBOX_CONFIG_FEATURE_DEVFS
181 bool "Use devfs names for all devices (obsolete)"
184 This is obsolete and will be going away at the end of 2008..
186 This tells busybox to look for names like /dev/loop/0 instead of
187 /dev/loop0. If your /dev directory has normal names instead of
188 devfs names, you don't want this.
190 config BUSYBOX_CONFIG_EJECT

380 There are two choices for command line behaviour, the interface
381 as used by LEAF/Linux Router Project, or a device table file.
383 'leaf' is traditionally what busybox follows, it allows multiple
384 devices of a particluar type to be created per command.
386 Device properties are passed as command line arguments.
388 'table' reads device properties from a file or stdin, allowing
389 a batch of unrelated devices to be made with one command.
390 User/group names are allowed as an alternative to uid/gid.
393 prompt "Choose makedevs behaviour"
394 depends on BUSYBOX_CONFIG_MAKEDEVS

438 config BUSYBOX_CONFIG_READAHEAD
441 depends on BUSYBOX_CONFIG_LFS
443 Preload the files listed on the command line into RAM cache so that
444 subsequent reads on these files will not block on disk I/O.
446 This applet just calls the readahead(2) system call on each file.
447 It is mainly useful in system startup scripts to preload files
448 or executables before they are used. When used at the right time
449 (in particular when a CPU bound process is running) it can
450 significantly speed up system startup.
452 As readahead(2) blocks until each file has been read, it is best to
453 run this applet as a background job.
455 config BUSYBOX_CONFIG_RUNLEVEL
459 find the current and previous system runlevel.
461 This applet uses utmp but does not rely on busybox supporing
462 utmp on purpose. It is used by e.g. emdebian via /etc/init.d/rc.
464 config BUSYBOX_CONFIG_RX
468 Receive files using the Xmodem protocol.
470 config BUSYBOX_CONFIG_SETSID

499 config BUSYBOX_CONFIG_TIME
503 The time command runs the specified program with the given arguments.
504 When the command finishes, time writes a message to standard output
505 giving timing statistics about this program run.
507 config BUSYBOX_CONFIG_TTYSIZE
511 A replacement for "stty size". Unlike stty, can report only width,
512 only height, or both, in any order. It also does not complain on error,
513 but returns default 80x24. Usage in shell scripts: width=`ttysize w`.
515 config BUSYBOX_CONFIG_WATCHDOG
519 The watchdog utility is used with hardware or software watchdog
520 device drivers. It opens the specified watchdog device special file
521 and periodically writes a magic character to the device. If the
522 watchdog applet ever fails to write the magic character within a
523 certain amount of time, the watchdog device assumes the system has
524 hung, and will cause the hardware to reboot.
