# # For a description of the syntax of this configuration file, # see scripts/kbuild/config-language.txt. # menu "Miscellaneous Utilities" config ADJTIMEX bool "adjtimex" default n help Adjtimex reads and optionally sets adjustment parameters for the Linux clock adjustment algorithm. config BBCONFIG bool "bbconfig" default n help The bbconfig applet will print the config file with which busybox was built. config CHAT bool "chat" default n help Simple chat utility. config FEATURE_CHAT_NOFAIL bool "Enable NOFAIL expect strings" depends on CHAT default y help When enabled expect strings which are started with a dash trigger no-fail mode. That is when expectation is not met within timeout the script is not terminated but sends next SEND string and waits for next EXPECT string. This allows to compose far more flexible scripts. config FEATURE_CHAT_TTY_HIFI bool "Force STDIN to be a TTY" depends on CHAT default n help Original chat always treats STDIN as a TTY device and sets for it so-called raw mode. This option turns on such behaviour. config FEATURE_CHAT_IMPLICIT_CR bool "Enable implicit Carriage Return" depends on CHAT default y help When enabled make chat to terminate all SEND strings with a "\r" unless "\c" is met anywhere in the string. config FEATURE_CHAT_SWALLOW_OPTS bool "Swallow options" depends on CHAT default n help Busybox chat require no options. To make it not fail when used in place of original chat (which has a bunch of options) turn this on. config FEATURE_CHAT_SEND_ESCAPES bool "Support weird SEND escapes" depends on CHAT default n help Original chat uses some escape sequences in SEND arguments which are not sent to device but rather performs special actions. E.g. "\K" means to send a break sequence to device. "\d" delays execution for a second, "\p" -- for a 1/100 of second. Before turning this option on think twice: do you really need them? config FEATURE_CHAT_VAR_ABORT_LEN bool "Support variable-length ABORT conditions" depends on CHAT default n help Original chat uses fixed 50-bytes length ABORT conditions. Say N here. config FEATURE_CHAT_CLR_ABORT bool "Support revoking of ABORT conditions" depends on CHAT default n help Support CLR_ABORT directive. config CHRT bool "chrt" default n help manipulate real-time attributes of a process. This requires sched_{g,s}etparam support in your libc. config CROND bool "crond" default n select FEATURE_SUID select FEATURE_SYSLOG help Crond is a background daemon that parses individual crontab files and executes commands on behalf of the users in question. This is a port of dcron from slackware. It uses files of the format /var/spool/cron/crontabs/<username> files, for example: $ cat /var/spool/cron/crontabs/root # Run daily cron jobs at 4:40 every day: 40 4 * * * /etc/cron/daily > /dev/null 2>&1 config DEBUG_CROND_OPTION bool "Support option -d to redirect output to stderr" depends on CROND default n help -d sets loglevel to 0 (most verbose) and directs all output to stderr. config FEATURE_CROND_CALL_SENDMAIL bool "Using /usr/sbin/sendmail?" default n depends on CROND help Support calling /usr/sbin/sendmail for send cmd outputs. config CRONTAB bool "crontab" default n select FEATURE_SUID help Crontab manipulates the crontab for a particular user. Only the superuser may specify a different user and/or crontab directory. Note that Busybox binary must be setuid root for this applet to work properly. config DC bool "dc" default n help Dc is a reverse-polish desk calculator which supports unlimited precision arithmetic. config DEVFSD bool "devfsd (obsolete)" default n select FEATURE_SYSLOG help This is deprecated, and will be removed at the end of 2008. Provides compatibility with old device names on a devfs systems. You should set it to true if you have devfs enabled. The following keywords in devsfd.conf are supported: "CLEAR_CONFIG", "INCLUDE", "OPTIONAL_INCLUDE", "RESTORE", "PERMISSIONS", "EXECUTE", "COPY", "IGNORE", "MKOLDCOMPAT", "MKNEWCOMPAT","RMOLDCOMPAT", "RMNEWCOMPAT". But only if they are written UPPERCASE!!!!!!!! config DEVFSD_MODLOAD bool "Adds support for MODLOAD keyword in devsfd.conf" default n depends on DEVFSD help This actually doesn't work with busybox modutils but needs the external modutils. config DEVFSD_FG_NP bool "Enables the -fg and -np options" default n depends on DEVFSD help -fg Run the daemon in the foreground. -np Exit after parsing the configuration file. Do not poll for events. config DEVFSD_VERBOSE bool "Increases logging (and size)" default n depends on DEVFSD help Increases logging to stderr or syslog. config FEATURE_DEVFS bool "Use devfs names for all devices (obsolete)" default n help This is obsolete and will be going away at the end of 2008.. This tells busybox to look for names like /dev/loop/0 instead of /dev/loop0. If your /dev directory has normal names instead of devfs names, you don't want this. config EJECT bool "eject" default n help Used to eject cdroms. (defaults to /dev/cdrom) config FEATURE_EJECT_SCSI bool "SCSI support" default n depends on EJECT help Add the -s option to eject, this allows to eject SCSI-Devices and usb-storage devices. config FBSPLASH bool "fbsplash" default n help Shows splash image and progress bar on framebuffer device. Can be used during boot phase of an embedded device. ~2kb. Usage: - use kernel option 'vga=xxx' or otherwise enable fb device. - put somewhere fbsplash.cfg file and an image in .ppm format. - $ setsid fbsplash [params] & -c: hide cursor -d /dev/fbN: framebuffer device (if not /dev/fb0) -s path_to_image_file (can be "-" for stdin) -i path_to_cfg_file (can be "-" for stdin) -f path_to_fifo (can be "-" for stdin) - if you want to run it only in presence of kernel parameter: grep -q "fbsplash=on" </proc/cmdline && setsid fbsplash [params] & - commands for fifo: "NN" (ASCII decimal number) - percentage to show on progress bar "exit" - well you guessed it config INOTIFYD bool "inotifyd" default n help Simple inotify daemon. Reports filesystem changes. Requires kernel >= 2.6.13 config LAST bool "last" default n select FEATURE_WTMP help 'last' displays a list of the last users that logged into the system. choice prompt "Choose last implementation" depends on LAST default FEATURE_LAST_SMALL config FEATURE_LAST_SMALL bool "small" help This is a small version of last with just the basic set of features. config FEATURE_LAST_FANCY bool "huge" help 'last' displays detailed information about the last users that logged into the system (mimics sysvinit last). +900 bytes. endchoice config LESS bool "less" default n help 'less' is a pager, meaning that it displays text files. It possesses a wide array of features, and is an improvement over 'more'. config FEATURE_LESS_MAXLINES int "Max number of input lines less will try to eat" default 9999999 depends on LESS config FEATURE_LESS_BRACKETS bool "Enable bracket searching" default y depends on LESS help This option adds the capability to search for matching left and right brackets, facilitating programming. config FEATURE_LESS_FLAGS bool "Enable extra flags" default y depends on LESS help The extra flags provided do the following: The -M flag enables a more sophisticated status line. The -m flag enables a simpler status line with a percentage. config FEATURE_LESS_FLAGCS bool "Enable flag changes" default n depends on LESS help This enables the ability to change command-line flags within less itself. config FEATURE_LESS_MARKS bool "Enable marks" default n depends on LESS help Marks enable positions in a file to be stored for easy reference. config FEATURE_LESS_REGEXP bool "Enable regular expressions" default n depends on LESS help Enable regular expressions, allowing complex file searches. config HDPARM bool "hdparm" default n help Get/Set hard drive parameters. Primarily intended for ATA drives. Adds about 13k (or around 30k if you enable the FEATURE_HDPARM_GET_IDENTITY option).... config FEATURE_HDPARM_GET_IDENTITY bool "Support obtaining detailed information directly from drives" default y depends on HDPARM help Enables the -I and -i options to obtain detailed information directly from drives about their capabilities and supported ATA feature set. If no device name is specified, hdparm will read identify data from stdin. Enabling this option will add about 16k... config FEATURE_HDPARM_HDIO_SCAN_HWIF bool "Register an IDE interface (DANGEROUS)" default n depends on HDPARM help Enables the 'hdparm -R' option to register an IDE interface. This is dangerous stuff, so you should probably say N. config FEATURE_HDPARM_HDIO_UNREGISTER_HWIF bool "Un-register an IDE interface (DANGEROUS)" default n depends on HDPARM help Enables the 'hdparm -U' option to un-register an IDE interface. This is dangerous stuff, so you should probably say N. config FEATURE_HDPARM_HDIO_DRIVE_RESET bool "Perform device reset (DANGEROUS)" default n depends on HDPARM help Enables the 'hdparm -w' option to perform a device reset. This is dangerous stuff, so you should probably say N. config FEATURE_HDPARM_HDIO_TRISTATE_HWIF bool "Tristate device for hotswap (DANGEROUS)" default n depends on HDPARM help Enables the 'hdparm -x' option to tristate device for hotswap, and the '-b' option to get/set bus state. This is dangerous stuff, so you should probably say N. config FEATURE_HDPARM_HDIO_GETSET_DMA bool "Get/set using_dma flag (DANGEROUS)" default n depends on HDPARM help Enables the 'hdparm -d' option to get/set using_dma flag. This is dangerous stuff, so you should probably say N. config MAKEDEVS bool "makedevs" default n help 'makedevs' is a utility used to create a batch of devices with one command. . There are two choices for command line behaviour, the interface as used by LEAF/Linux Router Project, or a device table file. . 'leaf' is traditionally what busybox follows, it allows multiple devices of a particluar type to be created per command. e.g. /dev/hda[0-9] Device properties are passed as command line arguments. . 'table' reads device properties from a file or stdin, allowing a batch of unrelated devices to be made with one command. User/group names are allowed as an alternative to uid/gid. choice prompt "Choose makedevs behaviour" depends on MAKEDEVS default FEATURE_MAKEDEVS_TABLE config FEATURE_MAKEDEVS_LEAF bool "leaf" config FEATURE_MAKEDEVS_TABLE bool "table" endchoice config MAN bool "man" default n help Format and display manual pages. config MICROCOM bool "microcom" default n help The poor man's minicom utility for chatting with serial port devices. config MOUNTPOINT bool "mountpoint" default n help mountpoint checks if the directory is a mountpoint. config MT bool "mt" default n help mt is used to control tape devices. You can use the mt utility to advance or rewind a tape past a specified number of archive files on the tape. config RAIDAUTORUN bool "raidautorun" default n help raidautorun tells the kernel md driver to search and start RAID arrays. config READAHEAD bool "readahead" default n depends on LFS help Preload the files listed on the command line into RAM cache so that subsequent reads on these files will not block on disk I/O. This applet just calls the readahead(2) system call on each file. It is mainly useful in system startup scripts to preload files or executables before they are used. When used at the right time (in particular when a CPU bound process is running) it can significantly speed up system startup. As readahead(2) blocks until each file has been read, it is best to run this applet as a background job. config RUNLEVEL bool "runlevel" default n help find the current and previous system runlevel. This applet uses utmp but does not rely on busybox supporing utmp on purpose. It is used by e.g. emdebian via /etc/init.d/rc. config RX bool "rx" default n help Receive files using the Xmodem protocol. config SETSID bool "setsid" default n help setsid runs a program in a new session config STRINGS bool "strings" default n help strings prints the printable character sequences for each file specified. config TASKSET bool "taskset" default n help Retrieve or set a processes's CPU affinity. This requires sched_{g,s}etaffinity support in your libc. config FEATURE_TASKSET_FANCY bool "Fancy output" default y depends on TASKSET help Add code for fancy output. This merely silences a compiler-warning and adds about 135 Bytes. May be needed for machines with alot of CPUs. config TIME bool "time" default n help The time command runs the specified program with the given arguments. When the command finishes, time writes a message to standard output giving timing statistics about this program run. config TTYSIZE bool "ttysize" default n help A replacement for "stty size". Unlike stty, can report only width, only height, or both, in any order. It also does not complain on error, but returns default 80x24. Usage in shell scripts: width=`ttysize w`. config WATCHDOG bool "watchdog" default n help The watchdog utility is used with hardware or software watchdog device drivers. It opens the specified watchdog device special file and periodically writes a magic character to the device. If the watchdog applet ever fails to write the magic character within a certain amount of time, the watchdog device assumes the system has hung, and will cause the hardware to reboot. endmenu
