  12         help
  13           dmesg is used to examine or control the kernel ring buffer.  When the
  14           Linux kernel prints messages to the system log, they are stored in
  15           the kernel ring buffer.  You can use dmesg to print the kernel's ring
  16           buffer, clear the kernel ring buffer, change the size of the kernel
  17           ring buffer, and change the priority level at which kernel messages
  18           are also logged to the system console.  Enable this option if you
  19           wish to enable the 'dmesg' utility.

  25           fbset is used to show or change the settings of a Linux frame buffer
  26           device.  The frame buffer device provides a simple and unique

  54           fdflush is only needed when changing media on slightly-broken
  55           removable media drives.  It is used to make Linux believe that a
  56           hardware disk-change switch has been actuated, which causes Linux to
  57           forget anything it has cached from the previous media.  If you have
  58           such a slightly-broken drive, you will need to run fdflush every time
  59           you change a disk.  Most people have working hardware and can safely
  60           leave this disabled.

  72           The fdisk utility is used to divide hard disks into one or more
  73           logical disks, which are generally called partitions.  This utility
  74           can be used to list and edit the set of partitions or BSD style

  89           Enabling this option allows you to create or change a partition table
  90           and write those changes out to disk.  If you leave this option
  91           disabled, you will only be able to view the partition table.

 137         default n
 138         help
 139           Linux allows you to create ramdisks.  This utility allows you to
 140           delete them and completely free all memory that was used for the
 141           ramdisk.  For example, if you boot Linux into a ramdisk and later
 142           pivot_root, you may want to free the memory that is allocated to the
 143           ramdisk.  If you have no use for freeing memory from a ramdisk, leave

 150           The minix filesystem is a nice, small, compact, read-write filesystem
 151           with little overhead.  It is not a journaling filesystem however and
 152           can experience corruption if it is not properly unmounted or if the
 153           power goes off in the middle of a write.  This utility allows you to
 154           check for and attempt to repair any corruption that occurs to a minix
 155           filesystem.

 173           If you wish to be able to create version 2 minix filesystems, enable this.
 174           If you enabled 'mkfs_minix' then you almost certainly want to be using the
 175           version 2 filesystem support.

 179         default n
 180         help
 181           The getopt utility is used to break up (parse) options in command
 182           lines to make it easy to write complex shell scripts that also check
 183           for legal (and illegal) options.  If you want to write horribly
 184           complex shell scripts, or use some horribly complex shell script
 185           written by others, this utility may be for you.  Most people will
 186           wisely leave this disabled.

 188 config BUSYBOX_CONFIG_HEXDUMP
 189         bool "hexdump"
 190         default y
 191         help
 192           The hexdump utility is used to display binary data in a readable

 197         default n
 198         help
 199           The hwclock utility is used to read and set the hardware clock
 200           on a system.  This is primarily used to set the current time on
 201           shutdown in the hardware clock, so the hardware will keep the
 202           correct time when Linux is _not_ running.

 208         help
 209           By default, the hwclock utility only uses short options.  If you
 210           are overly fond of its long options, such as --hctosys, --utc, etc)
 211           then enable this option.

 214         bool "losetup"
 215         default n
 216         help
 217           losetup is used to associate or detach a loop device with a regular
 218           file or block device, and to query the status of a loop device.  This
 219           version does not currently support enabling data encryption.

 221 config BUSYBOX_CONFIG_MKSWAP
 222         bool "mkswap"
 223         default n
 224         help
 225           The mkswap utility is used to configure a file or disk partition as
 226           Linux swap space.  This allows Linux to use the entire file or
 227           partition as if it were additional RAM, which can greatly increase
 228           the capability of low-memory machines.  This additional memory is
 229           much slower than real RAM, but can be very helpful at preventing your
 230           applications being killed by the Linux out of memory (OOM) killer.
 231           Once you have created swap space using 'mkswap' you need to enable
 232           the swap space using the 'swapon' utility.
 233
 234 config BUSYBOX_CONFIG_MORE
 235         bool "more"
 236         default y
 237         help
 238           more is a simple utility which allows you to read text one screen
 239           sized page at a time.  If you want to read text that is larger than
 240           the screen, and you are using anything faster than a 300 baud modem,
 241           you will probably find this utility very helpful.  If you don't have
 242           any need to reading text files, you can leave this disabled.

 244 config BUSYBOX_CONFIG_FEATURE_USE_TERMIOS
 245         bool "  Use termios to manipulate the screen"
 246         default y
 247         depends on BUSYBOX_CONFIG_MORE
 248         help
 249           This option allows utilities such as 'more' and 'top' to determine
 250           the size of the screen.  If you leave this disabled, your utilities
 251           that display things on the screen will be especially primitive and
 252           will be unable to determine the current screen size, and will be
 253           unable to move the cursor.

 255 config BUSYBOX_CONFIG_PIVOT_ROOT
 256         bool "pivot_root"
 257         default y
 258         help
 259           The pivot_root utility swaps the mount points for the root filesystem
 260           with some other mounted filesystem.  This allows you to do all sorts
 261           of wild and crazy things with your Linux system and is far more
 262           powerful than 'chroot'.
 263
 264 config BUSYBOX_CONFIG_RDATE
 265         bool "rdate"
 266         default y
 267         help
 268           The rdate utility allows you to synchronize the date and time of your
 269           system clock with the date and time of a remote networked system using
 270           the RFC868 protocol, which is built into the inetd daemon on most
 271           systems.

 273 config BUSYBOX_CONFIG_SWAPONOFF
 274         bool "swaponoff"
 275         default n
 276         help
 277           This option enables both the 'swapon' and the 'swapoff' utilities.
 278           Once you have created some swap space using 'mkswap', you also need
 279           to enable your swap space with the 'swapon' utility.  The 'swapoff'
 280           utility is used, typically at system shutdown, to disable any swap
 281           space.  If you are not using any swap space, you can leave this
 282           option disabled.

 286         default y
 287         help
 288           All files and filesystems in Unix are arranged into one big directory
 289           tree.  The 'mount' utility is used to graft a filesystem onto a
 290           particular part of the tree.  A filesystem can either live on a block
 291           device, or it can be accessible over the network, as is the case with
 292           NFS filesystems.  Most people using BusyBox will also want to enable
 293           the 'mount' utility.

 306           When you want to remove a mounted filesystem from its current mount point,
 307           for example when you are shutting down the system, the 'umount' utility is
 308           the tool to use.  If you enabled the 'mount' utility, you almost certainly
 309           also want to enable 'umount'.

 327           Enabling this feature allows mount to use the '-o' loop options,
 328           which lets you loop mount files.  Mount will automagically setup and
 329           free the necessary loop devices so you do not need to mess with the
 330           'losetup' utility unless you really want to.  This is really
