+.SH NAME
+addpart \- tell the kernel about the existence of a partition
+.SH SYNOPSIS
+.B addpart
+.I device partition start length
+.SH DESCRIPTION
+.B addpart
+tells the Linux kernel about the existence of the specified partition.
+The command is a simple wrapper around the "add partition" ioctl.
+
+This command doesn't manipulate partitions on a block device.
+
+.SH PARAMETERS
+.TP
+.I device
+The disk device.
+.TP
+.I partition
+The partition number.
+.TP
+.I start
+The beginning of the partition (in 512-byte sectors).
+.TP
+.I length
+The length of the partition (in 512-byte sectors).
+
+.SH SEE ALSO

+.TH BLOCKDEV 8 "August 2010" "util-linux" "System Administration"
+.SH NAME
+blockdev \- call block device ioctls from the command line
+.SH SYNOPSIS
+.B blockdev
+.RB [ \-q ]
+.RB [ \-v ]
+.I command
+.RI [ command \&...\&]
+.I device
+.RI [ device \&...\&]
+.br
+.B blockdev
+.B \-\-report
+.RI [ device \&...\&]
+.br
+.B blockdev
+.RB \-h | \-V
+.SH DESCRIPTION
+The utility
+.B blockdev
+allows one to call block device ioctls from the command line.
+.SH OPTIONS
+.IP "\fB\-q\fP"
+Be quiet.
+.IP "\fB\-v\fP"
+Be verbose.
+.IP "\fB\-\-report\fP"
+Print a report for the specified device. It is possible to give multiple
+devices. If none is given, all devices which appear in /proc/partitions are
+shown. Note that the partition StartSec is in 512-byte sectors.
+.IP "\fB\-h\fR, \fB\-\-help\fR"
+Display help text and exit.
+.IP "\fB\-V\fR, \fB\-\-version\fR"
+Print version and exit.
+.SH COMMANDS
+It is possible to give multiple devices and multiple commands.
+.IP "\fB\-\-flushbufs\fP"
+Flush buffers.
+.IP "\fB\-\-getalignoff\fP"
+Get alignment offset.
+.IP "\fB\-\-getbsz\fP"
+Print blocksize in bytes.
+.IP "\fB\-\-getdiscardzeroes\fP"
+Get discard zeroes support status.
+.IP "\fB\-\-getfra\fP"
+Get filesystem readahead in 512-byte sectors.
+.IP "\fB\-\-getiomin\fP"
+Get minimum I/O size.
+.IP "\fB\-\-getioopt\fP"
+Get optimal I/O size.
+.IP "\fB\-\-getmaxsect\fP"
+Get max sectors per request
+.IP "\fB\-\-getpbsz\fP"
+Get physical block (sector) size.
+.IP "\fB\-\-getra\fP"
+Print readahead (in 512-byte sectors).
+.IP "\fB\-\-getro\fP"
+Get read-only. Print 1 if the device is read-only, 0 otherwise.
+.IP "\fB\-\-getsize64\fP"
+Print device size in bytes.
+.IP "\fB\-\-getsize\fP"
+Print device size (32-bit!) in sectors. Deprecated in favor of the \-\-getsz option.
+.IP "\fB\-\-getss\fP"
+Print logical sector size in bytes \(en usually 512.
+.IP "\fB\-\-getsz\fP"
+Get size in 512-byte sectors.
+.IP "\fB\-\-rereadpt\fP"
+Reread partition table
+.IP "\fB\-\-setbsz\fP \fIbytes\fP"
+Set blocksize. Note that the block size is specific to the current file
+descriptor opening the block device, so the change of block size only persists
+for as long as blockdev has the device open, and is lost once blockdev exits.
+.IP "\fB\-\-setfra\fP \fIsectors\fP"
+Set filesystem readahead (same like \-\-setra on 2.6 kernels).
+.IP "\fB\-\-setra\fP \fIsectors\fP"
+Set readahead (in 512-byte sectors).
+.IP "\fB\-\-setro\fP"
+Set read-only. The currently active access to the device may not be affected by the change. For example
+filesystem already mounted in read-write mode will not be affected. The change applies after remount.
+.IP "\fB\-\-setrw\fP"
+Set read-write.

+.TH CFDISK 8 "March 2014" "util-linux" "System Administration"
+.SH NAME
+cfdisk \- display or manipulate a disk partition table
+.SH SYNOPSIS
+.B cfdisk
+[options]
+.RI [ device ]
+.SH DESCRIPTION
+.B cfdisk
+is a curses-based program for partitioning any block device.
+The default device is
+.IR /dev/sda .
+
+Note that
+.B cfdisk
+provides basic partitioning functionality with a user-friendly interface.
+If you need advanced features, use
+.BR fdisk (8)
+instead.
+
+Since version 2.25
+.B cfdisk
+supports MBR (DOS), GPT, SUN and SGI disk labels, but no longer provides any
+functionality for CHS (Cylinder-Head-Sector) addressing. CHS has
+never been important for Linux, and this addressing concept does not make any
+sense for new devices.
+
+Since version 2.25
+.B cfdisk
+also does not provide a 'print' command any more.
+This functionality is provided by the utilities
+.BR partx (8)
+and
+.BR lsblk (8)
+in a very comfortable and rich way.
+
+If you want to remove an old partition table from a device, use
+.BR wipefs (8).
+
+.SH OPTIONS
+.TP
+.BR \-h , " \-\-help"
+Display help text and exit.
+.TP
+.BR \-L , " \-\-color" [ = \fIwhen\fR]
+Colorize the output. The optional argument \fIwhen\fP
+can be \fBauto\fR, \fBnever\fR or \fBalways\fR. If the \fIwhen\fR argument is omitted,
+it defaults to \fBauto\fR. The colors can be disabled, for the current built-in default
+see \fB\-\-help\fR output. See also the COLORS section.
+.TP
+.BR \-V , " \-\-version"
+Display version information and exit.
+.TP
+.BR \-z , " \-\-zero"
+Start with an in-memory zeroed partition table. This option does not zero the
+partition table on the disk; rather, it simply starts the program without
+reading the existing partition table. This option allows you to create a new
+partition table from scratch or from an sfdisk-compatible script.
+
+.SH COMMANDS
+The commands for
+.B cfdisk
+can be entered by pressing the corresponding key (pressing
+.I Enter
+after the command is not necessary). Here is a list of the available
+commands:
+.TP
+.B b
+Toggle the bootable flag of the current partition. This allows you to
+select which primary partition is bootable on the drive. This command may not
+be available for all partition label types.
+.TP
+.B d
+Delete the current partition. This will convert the current partition
+into free space and merge it with any free space immediately
+surrounding the current partition. A partition already marked as free
+space or marked as unusable cannot be deleted.
+.TP
+.B h
+Show the help screen.
+.TP
+.B n
+Create a new partition from free space.
+.B cfdisk
+then prompts you for the size of the partition you want to create.
+The default size is equal to the entire available free space at the current
+position.
+
+The size may be followed by a multiplicative suffix: KiB (=1024),
+MiB (=1024*1024), and so on for GiB, TiB, PiB, EiB, ZiB and YiB
+(the "iB" is optional, e.g. "K" has the same meaning as "KiB").
+.TP
+.B q
+Quit the program. This will exit the program without writing any data to
+the disk.
+.TP
+.B s
+Sort the partitions in ascending start-sector order. When deleting and
+adding partitions, it is likely that the numbering of the partitions will
+no longer match their order on the disk. This command restores that match.
+.TP
+.B t
+Change the partition type. By default, new partitions are created as
+.I Linux
+partitions.
+.TP
+.B u
+Dump the current in-memory partition table to an sfdisk-compatible script file.
+.sp
+The script files are compatible between \fBcfdisk\fR, \fBfdisk\fR, \fBsfdisk\fR
+and other libfdisk applications. For more details see
+.BR sfdisk (8).
+.sp
+It is also possible to load an sfdisk-script into \fBcfdisk\fR if there is
+no partition table on the device or when you start \fBcfdisk\fR with the
+\fB--zero\fR command-line option.
+.TP
+.B W
+Write the partition table to disk (you must enter an uppercase W). Since
+this might destroy data on the disk, you must either confirm or deny
+the write by entering `yes' or `no'. If you enter `yes',
+.B cfdisk
+will write the partition table to disk and then tell the kernel to re-read the
+partition table from the disk.
+
+The re-reading of the partition table does not always work. In such a
+case you need to inform the kernel about any new partitions by using
+.BR partprobe (8)
+or
+.BR partx (8),
+or by rebooting the system.
+.TP
+.B x
+Toggle extra information about a partition.
+.TP
+.IR "Up Arrow" , " Down Arrow"
+Move the cursor to the previous or next partition. If there are more
+partitions than can be displayed on a screen, you can display the next
+(previous) set of partitions by moving down (up) at the last (first)
+partition displayed on the screen.
+.TP
+.IR "Left Arrow" , " Right Arrow"
+Select the preceding or the next menu item. Hitting \fIEnter\fR will
+execute the currently selected item.
+
+.PP
+All commands can be entered with either uppercase or lowercase
+letters (except for
+.BR W rite).
+When in a submenu or at a prompt, you can hit the
+.I Esc
+key to return to the main menu.
+
+.SH COLORS
+Implicit coloring can be disabled by creating the empty file
+.IR /etc/terminal-colors.d/cfdisk.disable .
+
+See
+.BR terminal-colors.d (5)
+for more details about colorization configuration.
+
+.B cfdisk
+does not support color customization with a color-scheme file.
+
+.SH ENVIRONMENT
+.IP CFDISK_DEBUG=all
+enables cfdisk debug output.
+.IP LIBFDISK_DEBUG=all
+enables libfdisk debug output.
+.IP LIBBLKID_DEBUG=all
+enables libblkid debug output.
+.IP LIBSMARTCOLS_DEBUG=all
+enables libsmartcols debug output.
+.IP LIBSMARTCOLS_DEBUG_PADDING=on
+use visible padding characters. Requires enabled LIBSMARTCOLS_DEBUG.
+
+.SH "SEE ALSO"
+.BR fdisk (8),
+.BR parted (8),
+.BR partprobe (8),
+.BR partx (8),
+.BR sfdisk (8)
+.SH AUTHOR
+Karel Zak <kzak@redhat.com>
+.PP
+The current cfdisk implementation is based on the original cfdisk
+from Kevin E. Martin (martin@cs.unc.edu).
+
+.SH AVAILABILITY
+The cfdisk command is part of the util-linux package and is available from
+https://www.kernel.org/pub/linux/utils/util-linux/.

+.TH FDFORMAT 8 "July 2014" "util-linux" "System Administration"
+.SH NAME
+fdformat \- low-level format a floppy disk
+.SH SYNOPSIS
+.B fdformat
+.RI [options] " device"
+.SH DESCRIPTION
+.B fdformat
+does a low-level format on a floppy disk.
+.I device
+is usually one of the following (for floppy devices the major = 2, and the
+minor is shown for informational purposes only):
+.sp
+.nf
+.RS
+/dev/fd0d360 (minor = 4)

+/dev/fd1h1200 (minor = 9)
+/dev/fd1D360 (minor = 13)
+/dev/fd1H360 (minor = 13)
+/dev/fd1D720 (minor = 17)
+/dev/fd1H720 (minor = 17)
+/dev/fd1h360 (minor = 21)
+/dev/fd1h720 (minor = 25)
+/dev/fd1H1440 (minor = 29)
+.RE
+.fi
+.PP
+The generic floppy devices, /dev/fd0 and /dev/fd1, will fail to work with
+.B fdformat
+when a non-standard format is being used, or if the format has not been
+autodetected earlier. In this case, use
+.BR setfdprm (8)
+to load the disk parameters.
+.SH OPTIONS
+.TP
+\fB\-f\fR, \fB\-\-from\fR \fIN\fR
+Start at the track \fIN\fR (default is 0).
+.TP
+\fB\-t\fR, \fB\-\-to\fR \fIN\fR
+Stop at the track \fIN\fR.
+.TP
+\fB\-r\fR, \fB\-\-repair\fR \fIN\fR
+Try to repair tracks failed during the verification (max \fIN\fR retries).
+.TP
+\fB\-n\fR, \fB\-\-no\-verify\fR
+Skip the verification that is normally performed after the formatting.
+.TP
+\fB\-V\fR, \fB\-\-version\fR
+Display version information and exit.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Display help text and exit.

+.SH NAME
+fdisk \- manipulate disk partition table
+
+.SH SYNOPSIS
+.B fdisk
+[options]
+.I device
+.sp
+.B fdisk \-l
+.RI [ device ...]
+
+.SH DESCRIPTION
+.B fdisk
+is a dialog-driven program for creation and manipulation of partition tables.
+It understands GPT, MBR, Sun, SGI and BSD partition tables.
+
+Block devices can be divided into one or more logical disks called
+.IR partitions .
+This division is recorded in the
+.IR "partition table" ,
+usually found in sector 0 of the disk.
+(In the BSD world one talks about `disk slices' and a `disklabel'.)
+
+All partitioning is driven by device I/O limits (the topology) by default.
+.B fdisk
+is able to optimize the disk layout for a 4K-sector size and use an alignment offset on
+modern devices for MBR and GPT. It is always a good idea to follow \fBfdisk\fR's defaults
+as the default values (e.g. first and last partition sectors) and partition
+sizes specified by the +/-<size>{M,G,...} notation are always aligned according
+to the device properties.
+
+Note that
+.BR partx (8)
+provides a rich interface for scripts to print disk layouts,
+.B fdisk
+is mostly designed for humans. Backward compatibility in the output of
+.B fdisk
+is not guaranteed. The input (the commands) should always be backward compatible.
+
+.SH OPTIONS
+.TP
+\fB\-b\fR, \fB\-\-sector\-size\fR \fIsectorsize\fP
+Specify the sector size of the disk. Valid values are 512, 1024, 2048, and 4096.
+(Recent kernels know the sector size. Use this option only on old kernels or
+to override the kernel's ideas.) Since util-linux-2.17, \fBfdisk\fR differentiates
+between logical and physical sector size. This option changes both sector sizes to
+.IB sectorsize .
+.TP
+\fB\-B\fR, \fB\-\-protect\-boot\fP
+Don't erase the begin of the first disk sector when create a new disk label. This
+feature is supported for GPT and MBR.
+.TP
+\fB\-c\fR, \fB\-\-compatibility\fR[=\fImode\fR]
+Specify the compatibility mode, 'dos' or 'nondos'. The default is non-DOS
+mode. For backward compatibility, it is possible to use the option without
+the \fImode\fR argument -- then the default is used. Note that the optional
+\fImode\fR argument cannot be separated from the \fB-c\fR option by a space,
+the correct form is for example '-c=dos'.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Display a help text and exit.
+.TP
+\fB\-L\fR, \fB\-\-color\fR[=\fIwhen\fR]
+Colorize the output. The optional argument \fIwhen\fP
+can be \fBauto\fR, \fBnever\fR or \fBalways\fR. If the \fIwhen\fR argument is omitted,
+it defaults to \fBauto\fR. The colors can be disabled; for the current built-in default
+see the \fB\-\-help\fR output. See also the \fBCOLORS\fR section.
+.TP
+\fB\-l\fR, \fB\-\-list\fR
+List the partition tables for the specified devices and then exit.
+If no devices are given, those mentioned in
+.I /proc/partitions
+(if that file exists) are used.
+.TP
+.BR \-o , " \-\-output " \fIlist\fP
+Specify which output columns to print. Use
+.B \-\-help
+to get a list of all supported columns.
+
+The default list of columns may be extended if \fIlist\fP is
+specified in the format \fI+list\fP (e.g. \fB-o +UUID\fP).
+.TP
+\fB\-s\fR, \fB\-\-getsz\fR
+Print the size in 512-byte sectors of each given block device. This option is DEPRECATED
+in favour of
+.BR blockdev (1).
+.TP
+\fB\-t\fR, \fB\-\-type\fR \fItype\fR
+Enable support only for disklabels of the specified \fItype\fP, and disable
+support for all other types.
+.TP
+\fB\-u\fR, \fB\-\-units\fR[=\fIunit\fR]
+When listing partition tables, show sizes in 'sectors' or in 'cylinders'. The
+default is to show sizes in sectors. For backward compatibility, it is possible
+to use the option without the \fIunit\fR argument -- then the default is used.
+Note that the optional \fIunit\fR argument cannot be separated from the \fB-u\fR
+option by a space, the correct form is for example '-u=cylinders'.
+
+.TP
+\fB\-C\fR, \fB\-\-cylinders\fR \fInumber\fR
+Specify the number of cylinders of the disk.
+I have no idea why anybody would want to do so.
+.TP
+\fB\-H\fR, \fB\-\-heads\fR \fInumber\fR
+Specify the number of heads of the disk. (Not the physical number,
+of course, but the number used for partition tables.)
+Reasonable values are 255 and 16.
+.TP
+\fB\-S\fR, \fB\-\-sectors\fR \fInumber\fR
+Specify the number of sectors per track of the disk.
+(Not the physical number, of course, but the number used for
+partition tables.) A reasonable value is 63.
+
+.TP
+\fB\-w\fR, \fB\-\-wipe\fR \fIwhen\fR
+Wipe filesystem, RAID and partition-table signatures from the device, in order
+to avoid possible collisions. The argument \fIwhen\fR can be \fBauto\fR,
+\fBnever\fR or \fBalways\fR. When this option is not given, the default is
+\fBauto\fR, in which case signatures are wiped only when in interactive mode.
+In all cases detected signatures are reported by warning messages
+before a new partition table is created. See also
+.BR wipefs (8)
+command.
+
+.TP
+\fB\-W\fR, \fB\-\-wipe-partition\fR \fIwhen\fR
+Wipe filesystem, RAID and partition-table signatures from a newly created
+partitions, in order to avoid possible collisions. The argument \fIwhen\fR can
+be \fBauto\fR, \fBnever\fR or \fBalways\fR. When this option is not given, the
+default is \fBauto\fR, in which case signatures are wiped only when in
+interactive mode and after confirmation by user. In all cases detected
+signatures are reported by warning messages before a new partition is
+created. See also
+.BR wipefs (8)
+command.
+
+.TP
+\fB\-V\fR, \fB\-\-version\fR
+Display version information and exit.
+
+.SH DEVICES
+The
+.I device
+is usually /dev/sda, /dev/sdb or so. A device name refers to the entire disk.
+Old systems without libata (a library used inside the Linux kernel to support
+ATA host controllers and devices) make a difference between IDE and SCSI disks.
+In such cases the device name will be /dev/hd* (IDE) or /dev/sd* (SCSI).
+
+The
+.I partition
+is a device name followed by a partition number. For example, /dev/sda1 is the
+first partition on the first hard disk in the system. See also Linux kernel
+documentation (the Documentation/devices.txt file).
+
+.SH SIZES
+The "last sector" dialog accepts partition size specified by number of sectors
+or by +/-<size>{K,B,M,G,...} notation.
+
+If the size is prefixed by '+' then it is interpreted as relative to the
+partition first sector. If the size is prefixed by '-' then it is interpreted
+as relative to the high limit (last available sector for the partition).
+
+In the case the size is specified in bytes than the number may be followed by
+the multiplicative suffixes KiB=1024, MiB=1024*1024, and so on for GiB, TiB,
+PiB, EiB, ZiB and YiB. The "iB" is optional, e.g. "K" has the same meaning as
+"KiB".
+
+The relative sizes are always aligned according to device I/O limits. The
++/-<size>{K,B,M,G,...} notation is recommended.
+
+For backward compatibility fdisk also accepts the suffixes KB=1000,
+MB=1000*1000, and so on for GB, TB, PB, EB, ZB and YB. These 10^N suffixes
+are deprecated.
+
+.SH SCRIPT FILES
+.B fdisk
+allows to read (by 'I' command) sfdisk compatible script files. The script is
+applied to in-memory partition table, and then it is possible to modify the
+partition table before you write it to the device.
+.PP
+And vice-versa it is possible to write the current in-memory disk layout
+to the script file by command 'O'.
+.PP
+The script files are compatible between cfdisk, sfdisk, fdisk and another
+libfdisk applications. For more details see
+.BR sfdisk (8).
+
+.SH DISK LABELS
+.B GPT (GUID Partition Table)
+.RS
+GPT is modern standard for the layout of the partition table. GPT uses 64-bit
+logical block addresses, checksums, UUIDs and names for partitions and an
+unlimited number of partitions (although the number of partitions is
+usually restricted to 128 in many partitioning tools).
+
+Note that the first sector is still reserved for a
+.B protective MBR
+in the GPT specification. It prevents MBR-only partitioning tools
+from mis-recognizing and overwriting GPT disks.
+
+GPT is always a better choice than MBR, especially on modern hardware with a UEFI
+boot loader.
+.RE
+
+.B DOS-type (MBR)
+.RS
+A DOS-type partition table can describe an unlimited number of partitions. In sector 0
+there is room for the description of 4 partitions (called `primary'). One of
+these may be an extended partition; this is a box holding logical partitions,
+with descriptors found in a linked list of sectors, each preceding the
+corresponding logical partitions. The four primary partitions, present or not,
+get numbers 1-4. Logical partitions are numbered starting from 5.
+
+In a DOS-type partition table the starting offset and the size of each
+partition is stored in two ways: as an absolute number of sectors (given in 32
+bits), and as a
+.B Cylinders/Heads/Sectors
+triple (given in 10+8+6 bits). The former is OK -- with 512-byte sectors this
+will work up to 2 TB. The latter has two problems. First, these C/H/S fields
+can be filled only when the number of heads and the number of sectors per track
+are known. And second, even if we know what these numbers should be, the 24
+bits that are available do not suffice. DOS uses C/H/S only, Windows uses
+both, Linux never uses C/H/S. The
+.B C/H/S addressing is deprecated
+and may be unsupported in some later fdisk version.
+
+.B Please, read the DOS-mode section if you want DOS-compatible partitions.
+.B fdisk
+does not care about cylinder boundaries by default.
+.RE
+
+.B BSD/Sun-type
+.RS
+A BSD/Sun disklabel can describe 8 partitions, the third of which should be a `whole
+disk' partition. Do not start a partition that actually uses its first sector
+(like a swap partition) at cylinder 0, since that will destroy the disklabel.
+Note that a
+.B BSD label
+is usually nested within a DOS partition.
+.RE
+
+.B IRIX/SGI-type
+.RS
+An IRIX/SGI disklabel can describe 16 partitions, the eleventh of which should be an entire
+`volume' partition, while the ninth should be labeled `volume header'. The
+volume header will also cover the partition table, i.e., it starts at block
+zero and extends by default over five cylinders. The remaining space in the
+volume header may be used by header directory entries. No partitions may
+overlap with the volume header. Also do not change its type or make some
+filesystem on it, since you will lose the partition table. Use this type of
+label only when working with Linux on IRIX/SGI machines or IRIX/SGI disks under
+Linux.
+.RE
+
+A sync() and an ioctl(BLKRRPART) (rereading the partition table from disk)
+are performed before exiting when the partition table has been updated.
+
+.SH "DOS mode and DOS 6.x WARNING"
+.B Note that all this is deprecated. You don't have to care about things like
+.B geometry and cylinders on modern operating systems. If you really want
+.B DOS-compatible partitioning then you have to enable DOS mode and cylinder
+.B units by using the '-c=dos -u=cylinders' fdisk command-line options.
+
+The DOS 6.x FORMAT command looks for some information in the first sector of
+the data area of the partition, and treats this information as more reliable
+than the information in the partition table. DOS FORMAT expects DOS FDISK to
+clear the first 512 bytes of the data area of a partition whenever a size
+change occurs. DOS FORMAT will look at this extra information even if the /U
+flag is given -- we consider this a bug in DOS FORMAT and DOS FDISK.
+
+The bottom line is that if you use \fBfdisk\fR or \fBcfdisk\fR to change the
+size of a DOS partition table entry, then you must also use
+.BR dd "(1) to " "zero the first 512 bytes"
+of that partition before using DOS FORMAT to format the partition. For
+example, if you were using \fBfdisk\fR to make a DOS partition table entry for
+/dev/sda1, then (after exiting \fBfdisk\fR and rebooting Linux so that the
+partition table information is valid) you would use the command "dd
+if=/dev/zero of=/dev/sda1 bs=512 count=1" to zero the first 512 bytes of the
+partition.
+
+.B fdisk
+usually obtains the disk geometry automatically. This is not necessarily the
+physical disk geometry (indeed, modern disks do not really have anything like a
+physical geometry, certainly not something that can be described in the simplistic
+Cylinders/Heads/Sectors form), but it is the disk geometry that MS-DOS uses for
+the partition table.
+
+Usually all goes well by default, and there are no problems if Linux is the
+only system on the disk. However, if the disk has to be shared with other
+operating systems, it is often a good idea to let an fdisk from another
+operating system make at least one partition. When Linux boots it looks at the
+partition table, and tries to deduce what (fake) geometry is required for good
+cooperation with other systems.
+
+Whenever a partition table is printed out in DOS mode, a consistency check is
+performed on the partition table entries. This check verifies that the
+physical and logical start and end points are identical, and that each
+partition starts and ends on a cylinder boundary (except for the first
+partition).
+
+Some versions of MS-DOS create a first partition which does not begin
+on a cylinder boundary, but on sector 2 of the first cylinder.
+Partitions beginning in cylinder 1 cannot begin on a cylinder boundary, but
+this is unlikely to cause difficulty unless you have OS/2 on your machine.
+
+For best results, you should always use an OS-specific partition table
+program. For example, you should make DOS partitions with the DOS FDISK
+program and Linux partitions with the Linux fdisk or Linux cfdisk programs.

+.SH NAME
+fsck \- check and repair a Linux filesystem
+.SH SYNOPSIS
+.B fsck
+.RB [ \-lsAVRTMNP ]
+.RB [ \-r
+.RI [ fd ]]
+.RB [ \-C
+.RI [ fd ]]
+.RB [ \-t
+.IR fstype ]
+.RI [ filesystem \&...\&]
+.RB [ \-\- ]
+.RI [ fs-specific-options ]
+.SH DESCRIPTION
+.B fsck
+is used to check and optionally repair one or more Linux filesystems.
+.I filesys
+can be a device name (e.g.
+.IR /dev/hdc1 ", " /dev/sdb2 ),
+a mount point (e.g.
+.IR / ", " /usr ", " /home ),
+or an ext2 label or UUID specifier (e.g.
+UUID=8868abf6-88c5-4a83-98b8-bfc24057f7bd or LABEL=root).
+Normally, the
+.B fsck
+program will try to handle filesystems on different physical disk drives
+in parallel to reduce the total amount of time needed to check all of them.
+.PP
+If no filesystems are specified on the command line, and the
+.B \-A
+option is not specified,
+.B fsck
+will default to checking filesystems in
+.I /etc/fstab
+serially. This is equivalent to the
+.B \-As
+options.
+.PP
+The exit code returned by
+.B fsck
+is the sum of the following conditions:
+.PP
+.RS
+.PD 0
+.TP
+.B 0
+No errors
+.TP
+.B 1
+Filesystem errors corrected
+.TP
+.B 2
+System should be rebooted
+.TP
+.B 4
+Filesystem errors left uncorrected
+.TP
+.B 8
+Operational error
+.TP
+.B 16
+Usage or syntax error
+.TP
+.B 32
+Checking canceled by user request
+.TP
+.B 128
+Shared-library error
+.PD
+.RE
+.PP
+The exit code returned when multiple filesystems are checked
+is the bit-wise OR of the exit codes for each
+filesystem that is checked.
+.PP
+In actuality,
+.B fsck
+is simply a front-end for the various filesystem checkers
+(\fBfsck\fR.\fIfstype\fR) available under Linux. The
+filesystem-specific checker is searched for in the
+PATH environment variable. If the PATH is undefined then
+fallback to "/sbin".
+.PP
+Please see the filesystem-specific checker manual pages for
+further details.
+.SH OPTIONS
+.TP
+.B \-l
+Create an exclusive
+.BR flock (2)
+lock file (/run/fsck/<diskname>.lock) for whole-disk device.
+This option can be used with one device only (this means that \fB\-A\fR and
+\fB\-l\fR are mutually exclusive). This option is recommended when more
+.BR fsck (8)
+instances are executed in the same time. The option is ignored when used for
+multiple devices or for non-rotating disks. \fBfsck\fR does not lock underlying
+devices when executed to check stacked devices (e.g.\& MD or DM) \(en this feature is
+not implemented yet.
+.TP
+.BR \-r \ [ \fIfd\fR ]
+Report certain statistics for each fsck when it completes. These statistics
+include the exit status, the maximum run set size (in kilobytes), the elapsed
+all-clock time and the user and system CPU time used by the fsck run. For
+example:
+
+/dev/sda1: status 0, rss 92828, real 4.002804, user 2.677592, sys 0.86186
+
+GUI front-ends may specify a file descriptor
+.IR fd ,
+in which case the progress bar information will be sent to that file descriptor
+in a machine parsable format. For example:
+
+/dev/sda1 0 92828 4.002804 2.677592 0.86186
+.TP
+.B \-s
+Serialize
+.B fsck
+operations. This is a good idea if you are checking multiple
+filesystems and the checkers are in an interactive mode. (Note:
+.BR e2fsck (8)
+runs in an interactive mode by default. To make
+.BR e2fsck (8)
+run in a non-interactive mode, you must either specify the
+.B \-p
+or
+.B \-a
+option, if you wish for errors to be corrected automatically, or the
+.B \-n
+option if you do not.)
+.TP
+.BI \-t " fslist"
+Specifies the type(s) of filesystem to be checked. When the
+.B \-A
+flag is specified, only filesystems that match
+.I fslist
+are checked. The
+.I fslist
+parameter is a comma-separated list of filesystems and options
+specifiers. All of the filesystems in this comma-separated list may be
+prefixed by a negation operator
+.RB ' no '
+or
+.RB ' ! ',
+which requests that only those filesystems not listed in
+.I fslist
+will be checked. If none of the filesystems in
+.I fslist
+is prefixed by a negation operator, then only those listed filesystems
+will be checked.
+.sp
+Options specifiers may be included in the comma-separated
+.IR fslist .
+They must have the format
+.BI opts= fs-option\fR.
+If an options specifier is present, then only filesystems which contain
+.I fs-option
+in their mount options field of
+.I /etc/fstab
+will be checked. If the options specifier is prefixed by a negation
+operator, then only
+those filesystems that do not have
+.I fs-option
+in their mount options field of
+.I /etc/fstab
+will be checked.
+.sp
+For example, if
+.B opts=ro
+appears in
+.IR fslist ,
+then only filesystems listed in
+.I /etc/fstab
+with the
+.B ro
+option will be checked.
+.sp
+For compatibility with Mandrake distributions whose boot scripts
+depend upon an unauthorized UI change to the
+.B fsck
+program, if a filesystem type of
+.B loop
+is found in
+.IR fslist ,
+it is treated as if
+.B opts=loop
+were specified as an argument to the
+.B \-t
+option.
+.sp
+Normally, the filesystem type is deduced by searching for
+.I filesys
+in the
+.I /etc/fstab
+file and using the corresponding entry.
+If the type cannot be deduced, and there is only a single filesystem
+given as an argument to the
+.B \-t
+option,
+.B fsck
+will use the specified filesystem type. If this type is not
+available, then the default filesystem type (currently ext2) is used.
+.TP
+.B \-A
+Walk through the
+.I /etc/fstab
+file and try to check all filesystems in one run. This option is
+typically used from the
+.I /etc/rc
+system initialization file, instead of multiple commands for checking
+a single filesystem.
+.sp
+The root filesystem will be checked first unless the
+.B \-P
+option is specified (see below). After that,
+filesystems will be checked in the order specified by the
+.I fs_passno
+(the sixth) field in the
+.I /etc/fstab
+file.
+Filesystems with a
+.I fs_passno
+value of 0 are skipped and are not checked at all. Filesystems with a
+.I fs_passno
+value of greater than zero will be checked in order,
+with filesystems with the lowest
+.I fs_passno
+number being checked first.
+If there are multiple filesystems with the same pass number,
+.B fsck
+will attempt to check them in parallel, although it will avoid running
+multiple filesystem checks on the same physical disk.
+.sp
+.B fsck
+does not check stacked devices (RAIDs, dm-crypt, \&...\&) in parallel with any other
+device. See below for FSCK_FORCE_ALL_PARALLEL setting. The /sys filesystem is
+used to determine dependencies between devices.
+.sp
+Hence, a very common configuration in
+.I /etc/fstab
+files is to set the root filesystem to have a
+.I fs_passno
+value of 1
+and to set all other filesystems to have a
+.I fs_passno
+value of 2. This will allow
+.B fsck
+to automatically run filesystem checkers in parallel if it is advantageous
+to do so. System administrators might choose
+not to use this configuration if they need to avoid multiple filesystem
+checks running in parallel for some reason \(en for example, if the
+machine in question is short on memory so that
+excessive paging is a concern.
+.sp
+.B fsck
+normally does not check whether the device actually exists before
+calling a filesystem specific checker. Therefore non-existing
+devices may cause the system to enter filesystem repair mode during
+boot if the filesystem specific checker returns a fatal error. The
+.I /etc/fstab
+mount option
+.B nofail
+may be used to have
+.B fsck
+skip non-existing devices.
+.B fsck
+also skips non-existing devices that have the special filesystem type
+.BR auto .
+.TP
+.BR \-C \ [ \fIfd\fR ]
+Display completion/progress bars for those filesystem checkers (currently
+only for ext[234]) which support them. \fBfsck\fR will manage the
+filesystem checkers so that only one of them will display
+a progress bar at a time. GUI front-ends may specify a file descriptor
+.IR fd ,
+in which case the progress bar information will be sent to that file descriptor.
+.TP
+.B \-M
+Do not check mounted filesystems and return an exit code of 0
+for mounted filesystems.
+.TP
+.B \-N
+Don't execute, just show what would be done.
+.TP
+.B \-P
+When the
+.B \-A
+flag is set, check the root filesystem in parallel with the other filesystems.
+This is not the safest thing in the world to do,
+since if the root filesystem is in doubt things like the
+.BR e2fsck (8)
+executable might be corrupted! This option is mainly provided
+for those sysadmins who don't want to repartition the root
+filesystem to be small and compact (which is really the right solution).
+.TP
+.B \-R
+When checking all filesystems with the
+.B \-A
+flag, skip the root filesystem. (This is useful in case the root
+filesystem has already been mounted read-write.)
+.TP
+.B \-T
+Don't show the title on startup.
+.TP
+.B \-V
+Produce verbose output, including all filesystem-specific commands
+that are executed.
+.TP
+\fB\-?\fR, \fB\-\-help\fR
+Display help text and exit.
+.TP
+\fB\-\-version\fR
+Display version information and exit.
+.SH FILESYSTEM SPECIFIC OPTIONS
+.B Options which are not understood by fsck are passed to the filesystem-specific checker!
+.PP
+These options
+.B must
+not take arguments, as there is no
+way for
+.B fsck
+to be able to properly guess which options take arguments and which
+don't.
+.PP
+Options and arguments which follow the
+.B \-\-
+are treated as filesystem-specific options to be passed to the
+filesystem-specific checker.
+.PP
+Please note that \fBfsck\fR is not
+designed to pass arbitrarily complicated options to filesystem-specific
+checkers. If you're doing something complicated, please just
+execute the filesystem-specific checker directly. If you pass
+.B fsck
+some horribly complicated options and arguments, and it doesn't do
+what you expect,
+.B don't bother reporting it as a bug.
+You're almost certainly doing something that you shouldn't be doing
+with
+.BR fsck .
+Options to different filesystem-specific fsck's are not standardized.
+.SH FILES
+.I /etc/fstab
+.SH ENVIRONMENT VARIABLES
+The
+.B fsck
+program's behavior is affected by the following environment variables:
+.TP
+.B FSCK_FORCE_ALL_PARALLEL
+If this environment variable is set,
+.B fsck
+will attempt to check all of the specified filesystems in parallel, regardless of
+whether the filesystems appear to be on the same device. (This is useful for
+RAID systems or high-end storage systems such as those sold by companies such
+as IBM or EMC.) Note that the fs_passno value is still used.
+.TP
+.B FSCK_MAX_INST
+This environment variable will limit the maximum number of filesystem
+checkers that can be running at one time. This allows configurations
+which have a large number of disks to avoid
+.B fsck
+starting too many filesystem checkers at once, which might overload
+CPU and memory resources available on the system. If this value is
+zero, then an unlimited number of processes can be spawned. This is
+currently the default, but future versions of
+.B fsck
+may attempt to automatically determine how many filesystem checks can
+be run based on gathering accounting data from the operating system.
+.TP
+.B PATH
+The
+.B PATH
+environment variable is used to find filesystem checkers.
+.TP
+.B FSTAB_FILE
+This environment variable allows the system administrator
+to override the standard location of the
+.I /etc/fstab
+file. It is also useful for developers who are testing
+.BR fsck .
+.TP
+.B LIBBLKID_DEBUG=all
+enables libblkid debug output.
+.TP
+.B LIBMOUNT_DEBUG=all
+enables libmount debug output.

+ * fsck --- A generic, parallelizing front-end for the fsck program.
+ * It will automatically try to run fsck programs in parallel if the
+ * devices are on separate spindles. It is based on the same ideas as
+ * the generic front end for fsck by David Engel and Fred van Kempen,
+ * but it has been completely rewritten from scratch to support
+ * parallel execution.
+ *
+ * Written by Theodore Ts'o, <tytso@mit.edu>
+ *
+ * Miquel van Smoorenburg (miquels@drinkel.ow.org) 20-Oct-1994:
+ * o Changed -t fstype to behave like with mount when -A (all file
+ * systems) or -M (like mount) is specified.
+ * o fsck looks if it can find the fsck.type program to decide
+ * if it should ignore the fs type. This way more fsck programs
+ * can be added without changing this front-end.
+ * o -R flag skip root file system.

+.SH NAME
+fsck.minix \- check consistency of Minix filesystem
+.SH SYNOPSIS
+.B fsck.minix
+[options]
+.I device
+.SH DESCRIPTION
+.B fsck.minix
+performs a consistency check for the Linux MINIX filesystem.
+.PP
+The program assumes the filesystem is quiescent.
+.B fsck.minix
+should not be used on a mounted device unless you can be sure nobody is
+writing to it. Remember that the kernel can write to device when it
+searches for files.
+.PP
+The \fIdevice\fR name will usually have the following form:
+.RS
+.TS
+tab(:);
+l l.
+/dev/hda[1\(en63]:IDE disk 1
+/dev/hdb[1\(en63]:IDE disk 2
+/dev/sda[1\(en15]:SCSI disk 1
+/dev/sdb[1\(en15]:SCSI disk 2
+.TE
+.RE
+.PP
+If the filesystem was changed, i.e., repaired, then
+.B fsck.minix
+will print "FILE SYSTEM HAS CHANGED" and will
+.BR sync (2)
+three times before exiting. There is
+.I no
+need to reboot after check.
+.SH WARNING
+.B fsck.minix
+should
+.B not
+be used on a mounted filesystem. Using
+.B fsck.minix
+on a mounted filesystem is very dangerous, due to the possibility that
+deleted files are still in use, and can seriously damage a perfectly good
+filesystem! If you absolutely have to run
+.B fsck.minix
+on a mounted filesystem, such as the root filesystem, make sure nothing
+is writing to the disk, and that no files are "zombies" waiting for
+deletion.
+.SH OPTIONS
+.TP
+\fB\-l\fR, \fB\-\-list\fR
+List all filenames.
+.TP
+\fB\-r\fR, \fB\-\-repair\fR
+Perform interactive repairs.
+.TP
+\fB\-a\fR, \fB\-\-auto\fR
+Perform automatic repairs. This option implies
+.B \-\-repair
+and serves to answer all of the questions asked with the default. Note
+that this can be extremely dangerous in the case of extensive filesystem
+damage.
+.TP
+\fB\-v\fR, \fB\-\-verbose\fR
+Be verbose.
+.TP
+\fB\-s\fR, \fB\-\-super\fR
+Output super-block information.
+.TP
+\fB\-m\fR, \fB\-\-uncleared\fR
+Activate MINIX-like "mode not cleared" warnings.
+.TP
+\fB\-f\fR, \fB\-\-force\fR
+Force a filesystem check even if the filesystem was marked as valid.
+Marking is done by the kernel when the filesystem is unmounted.
+.TP
+\fB\-V\fR, \fB\-\-version\fR
+Display version information and exit.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Display help text and exit.
+.SH DIAGNOSTICS
+There are numerous diagnostic messages. The ones mentioned here are the
+most commonly seen in normal usage.
+.PP
+If the device does not exist,
+.B fsck.minix
+will print "unable to read super block". If the device exists, but is not
+a MINIX filesystem,
+.B fsck.minix
+will print "bad magic number in super-block".
+.SH "EXIT CODES"
+The exit code returned by
+.B fsck.minix
+is the sum of the following:
+.PP
+.RS
+.PD 0
+.TP
+.B 0
+No errors
+.TP
+.B 3
+Filesystem errors corrected, system should be rebooted if filesystem was
+mounted
+.TP
+.B 4
+Filesystem errors left uncorrected
+.TP
+.B 7
+Combination of exit codes 3 and 4
+.TP
+.B 8
+Operational error
+.TP
+.B 16
+Usage or syntax error

+ */
+
+/*
+ * 09.11.91 - made the first rudimentary functions
+ *
+ * 10.11.91 - updated, does checking, no repairs yet.
+ * Sent out to the mailing-list for testing.
+ *
+ * 14.11.91 - Testing seems to have gone well. Added some
+ * correction-code, and changed some functions.
+ *
+ * 15.11.91 - More correction code. Hopefully it notices most
+ * cases now, and tries to do something about them.
+ *
+ * 16.11.91 - More corrections (thanks to Mika Jalava). Most
+ * things seem to work now. Yeah, sure.
+ *
+ *
+ * 19.04.92 - Had to start over again from this old version, as a
+ * kernel bug ate my enhanced fsck in February.
+ *
+ * 28.02.93 - added support for different directory entry sizes..
+ *
+ * Sat Mar 6 18:59:42 1993, faith@cs.unc.edu: Output namelen with
+ * super-block information
+ *
+ * Sat Oct 9 11:17:11 1993, faith@cs.unc.edu: make exit status conform
+ * to that required by fsutil
+ *
+ * Mon Jan 3 11:06:52 1994 - Dr. Wettstein (greg%wind.uucp@plains.nodak.edu)
+ * Added support for file system valid flag. Also
+ * added program_version variable and output of
+ * program name and version number when program
+ * is executed.
+ *
+ * 30.10.94 - added support for v2 filesystem
+ * (Andreas Schwab, schwab@issan.informatik.uni-dortmund.de)
+ *
+ * 10.12.94 - added test to prevent checking of mounted fs adapted
+ * from Theodore Ts'o's (tytso@athena.mit.edu) e2fsck
+ * program. (Daniel Quinlan, quinlan@yggdrasil.com)
+ *
+ * 01.07.96 - Fixed the v2 fs stuff to use the right #defines and such
+ * for modern libcs (janl@math.uio.no, Nicolai Langfeldt)
+ *
+ * 02.07.96 - Added C bit fiddling routines from rmk@ecs.soton.ac.uk
+ * (Russell King). He made them for ARM. It would seem
+ * that the ARM is powerful enough to do this in C whereas
+ * i386 and m64k must use assembly to get it fast >:-)
+ * This should make minix fsck systemindependent.
+ * (janl@math.uio.no, Nicolai Langfeldt)
+ *
+ * 04.11.96 - Added minor fixes from Andreas Schwab to avoid compiler
+ * warnings. Added mc68k bitops from
+ * Joerg Dorchain <dorchain@mpi-sb.mpg.de>.
+ *
+ * 06.11.96 - Added v2 code submitted by Joerg Dorchain, but written by
+ * Andreas Schwab.
+ *
+ * 1999-02-22 Arkadiusz Miśkiewicz <misiek@pld.ORG.PL>
+ * - added Native Language Support
+ *
+ * 2008-04-06 James Youngman <jay@gnu.org>
+ * - Issue better error message if we fail to open the device.
+ * - Restore terminal state if we get a fatal signal.
+ *
+ *
+ * I've had no time to add comments - hopefully the function names
+ * are comments enough. As with all file system checkers, this assumes
+ * the file system is quiescent - don't use it on a mounted device
+ * unless you can be sure nobody is writing to it (and remember that the
+ * kernel can write to it when it searches for files).

+.TH ISOSIZE 8 "June 2011" "util-linux" "System Administration"
+.SH NAME
+isosize \- output the length of an iso9660 filesystem
+.SH SYNOPSIS
+.B isosize
+.RI [options] " iso9660_image_file"
+.SH DESCRIPTION
+.PP
+This command outputs the length of an iso9660 filesystem that
+is contained in the specified file. This file may be a normal file or
+a block device (e.g.\& /dev/hdd or /dev/sr0). In the absence of
+any options (and errors), it will output the size of the iso9660
+filesystem in bytes. This can now be a large number (>> 4\ GB).
+.SH OPTIONS
+.TP
+.BR \-x , " \-\-sectors"
+Show the block count and block size in human-readable form.
+The output uses the term "sectors" for "blocks".
+.TP
+.BR \-d , " \-\-divisor " \fInumber\fR
+Only has an effect when
+.B \-x
+is not given. The value shown (if no errors)
+is the iso9660 file size in bytes divided by
+.IR number .
+So if
+.I number
+is the block size then the shown value will be the block count.
+.PP
+The size of the file (or block device) holding an iso9660
+filesystem can be marginally larger than the actual size of the
+iso9660 filesystem. One reason for this is that cd writers
+are allowed to add "run out" sectors at the end of an iso9660
+image.
+.SH "EXIT STATUS"
+.RS
+.PD 0
+.TP
+.B 0
+success
+.TP
+.B 1
+generic failure, such as invalid usage
+.TP
+.B 32
+all failed

+.B 64

+.PD

+.SH AVAILABILITY
+The isosize command is part of the util-linux package and is available from
+.UR https://\:www.kernel.org\:/pub\:/linux\:/utils\:/util-linux/
+Linux Kernel Archive
+.UE .

+.TH MKFS 8 "June 2011" "util-linux" "System Administration"
+.SH NAME
+mkfs \- build a Linux filesystem
+.SH SYNOPSIS
+.B mkfs
+[options]
+.RB [ \-t
+.IR type "] [" fs-options ] " device " [ size ]
+.SH DESCRIPTION
+.B This mkfs frontend is deprecated in favour of filesystem specific mkfs.<type> utils.
+.PP
+.B mkfs
+is used to build a Linux filesystem on a device, usually
+a hard disk partition. The
+.I device
+argument is either the device name (e.g.
+.IR /dev/hda1 ,
+.IR /dev/sdb2 ),
+or a regular file that shall contain the filesystem. The
+.I size
+argument is the number of blocks to be used for the filesystem.
+.PP
+The exit code returned by
+.B mkfs
+is 0 on success and 1 on failure.
+.PP
+In actuality,
+.B mkfs
+is simply a front-end for the various filesystem builders
+(\fBmkfs.\fIfstype\fR)
+available under Linux.
+The filesystem-specific builder is searched for via your PATH
+environment setting only.
+Please see the filesystem-specific builder manual pages for
+further details.
+.SH OPTIONS
+.TP
+.BR \-t , " \-\-type " \fItype\fR
+Specify the \fItype\fR of filesystem to be built.
+If not specified, the default filesystem type
+(currently ext2) is used.
+.TP
+.I fs-options
+Filesystem-specific options to be passed to the real filesystem builder.
+.TP
+.BR \-V , " \-\-verbose"
+Produce verbose output, including all filesystem-specific commands
+that are executed.
+Specifying this option more than once inhibits execution of any
+filesystem-specific commands.
+This is really only useful for testing.
+.TP
+.BR \-V , " \-\-version"
+Display version information and exit. (Option \fB\-V\fR will display
+version information only when it is the only parameter, otherwise it
+will work as \fB\-\-verbose\fR.)
+.TP
+.BR \-h , " \-\-help"
+Display help text and exit.
+.SH BUGS
+All generic options must precede and not be combined with
+filesystem-specific options.
+Some filesystem-specific programs do not automatically
+detect the device size and require the
+.I size
+parameter to be specified.
+.SH AUTHORS
+David Engel (david@ods.com)
+.br
+Fred N.\& van Kempen (waltje@uwalt.nl.mugnet.org)
+.br
+Ron Sommeling (sommel@sci.kun.nl)
+.br
+The manual page was shamelessly adapted from Remy Card's version
+for the ext2 filesystem.

+.TH MKFS.BFS 8 "July 2011" "util-linux" "System Administration"
+.SH NAME
+mkfs.bfs \- make an SCO bfs filesystem
+.SH SYNOPSIS
+.B mkfs.bfs
+.RI [options] " device " [ block-count ]
+.SH DESCRIPTION
+.B mkfs.bfs
+creates an SCO bfs filesystem on a block device
+(usually a disk partition or a file accessed via the loop device).
+.PP
+The
+.I block-count
+parameter is the desired size of the filesystem, in blocks.
+If nothing is specified, the entire partition will be used.
+.SH OPTIONS
+.TP
+.BR \-N , " \-\-inodes " \fInumber\fR
+Specify the desired \fInumber\fR of inodes (at most 512).
+If nothing is specified, some default number in the range 48\(en512 is picked
+depending on the size of the partition.
+.TP
+.BR \-V , " \-\-vname " \fIlabel\fR
+Specify the volume \fIlabel\fR. I have no idea if/where this is used.
+.TP
+.BR \-F , " \-\-fname " \fIname\fR
+Specify the filesystem \fIname\fR. I have no idea if/where this is used.
+.TP
+.BR \-v , " \-\-verbose"
+Explain what is being done.
+.TP
+.B \-c
+This option is silently ignored.
+.TP
+.B \-l
+This option is silently ignored.
+.TP
+.BR \-h , " \-\-help"
+Display help text and exit.
+.TP
+.BR \-V , " \-\-version"
+Display version information and exit.
+Option
+.B \-V
+only works as
+.B \-\-version
+when it is the only option.
+.SH "EXIT CODES"
+The exit code returned by
+.B mkfs.bfs
+is 0 when all went well, and 1 when something went wrong.
+.SH "SEE ALSO"
+.BR mkfs (8)
+.SH AVAILABILITY
+The mkfs.bfs command is part of the util-linux package and is available from

+.TH MKFS.CRAMFS 8 "April 2013" "util-linux" "System Administration"
+.SH NAME
+mkfs.cramfs \- make compressed ROM file system
+.SH SYNOPSIS
+.B mkfs.cramfs
+[options]
+.I directory file
+.SH DESCRIPTION
+Files on cramfs file systems are zlib-compressed one page at a time to
+allow random read access. The metadata is not compressed, but is
+expressed in a terse representation that is more space-efficient than
+conventional file systems.
+.PP
+The file system is intentionally read-only to simplify its design; random
+write access for compressed files is difficult to implement. cramfs
+ships with a utility (mkcramfs) to pack files into new cramfs images.
+.PP
+File sizes are limited to less than 16\ MB.
+.PP
+Maximum file system size is a little under 272\ MB. (The last file on the
+file system must begin before the 256\ MB block, but can extend past it.)
+.SH ARGUMENTS
+The
+.I directory
+is simply the root of the directory tree that we want to generate a
+compressed filesystem out of.
+.PP
+The
+.I file
+will contain the cram file system, which later can be mounted.
+.SH OPTIONS
+.TP
+\fB\-v\fR
+Enable verbose messaging.
+.TP
+\fB\-E\fR
+Treat all warnings as errors, which are reflected as command return value.
+.TP
+\fB\-b\fR \fIblocksize\fR
+Use defined block size, which has to be divisible by page size.
+.TP
+\fB\-e\fR \fIedition\fR
+Use defined file system edition number in superblock.
+.TP
+\fB\-N\fR \fIbig, little, host\fR
+Use defined endianness. Value defaults to
+.IR host .
+.TP
+\fB\-i\fR \fIfile\fR
+Insert a
+.I file
+to cramfs file system.
+.TP
+\fB\-n\fR \fIname\fR
+Set name of the cramfs file system.
+.TP
+\fB\-p\fR
+Pad by 512 bytes for boot code.
+.TP
+\fB\-s\fR
+This option is ignored. Originally the \-s turned on directory entry
+sorting.
+.TP
+\fB\-z\fR
+Make explicit holes.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Display help text and exit.
+.TP
+\fB\-V\fR, \fB\-\-version\fR
+Display version information and exit.
+.SH "EXIT STATUS"
+.RS
+.PD 0
+.TP
+.B 0
+success
+.TP
+.B 8
+operation error, such as unable to allocate memory
+.PD
+.RE
+.SH "SEE ALSO"
+.BR fsck.cramfs (8),
+.BR mount (8)
+.SH AVAILABILITY
+The example command is part of the util-linux package and is available from
+.UR https://\:www.kernel.org\:/pub\:/linux\:/utils\:/util-linux/
+Linux Kernel Archive
+.UE .

+.TH MKFS.MINIX 8 "June 2015" "util-linux" "System Administration"
+.SH NAME
+mkfs.minix \- make a Minix filesystem
+.SH SYNOPSIS
+.B mkfs.minix
+[options]
+.I device
+.RI [ size-in-blocks ]
+.SH DESCRIPTION
+.B mkfs.minix
+creates a Linux MINIX filesystem on a device (usually a disk partition).
+
+The
+.I device
+is usually of the following form:
+
+.nf
+.RS
+/dev/hda[1\(en8] (IDE disk 1)
+/dev/hdb[1\(en8] (IDE disk 2)
+/dev/sda[1\(en8] (SCSI disk 1)
+/dev/sdb[1\(en8] (SCSI disk 2)
+.RE
+.fi
+
+The device may be a block device or an image file of one, but this is not
+enforced. Expect not much fun on a character device :-).
+.PP
+The
+.I size-in-blocks
+parameter is the desired size of the file system, in blocks.
+It is present only for backwards compatibility.
+If omitted the size will be determined automatically.
+Only block counts strictly greater than 10 and strictly less than
+65536 are allowed.
+.SH OPTIONS
+.TP
+\fB\-c\fR, \fB\-\-check\fR
+Check the device for bad blocks before creating the filesystem. If any
+are found, the count is printed.
+.TP
+\fB\-n\fR, \fB\-\-namelength\fR \fIlength\fR
+Specify the maximum length of filenames. Currently, the only allowable
+values are 14 and 30 for file system versions 1 and 2. Version 3 allows
+only value 60. The default is 30.
+.TP
+\fB\-i\fR, \fB\-\-inodes\fR \fInumber\fR
+Specify the number of inodes for the filesystem.
+.TP
+\fB\-l\fR, \fB\-\-badblocks\fR \fIfilename\fR
+Read the list of bad blocks from
+.IR filename .
+The file has one bad-block number per line. The count of bad blocks read
+is printed.
+.TP
+.B \-1
+Make a Minix version 1 filesystem. This is the default.
+.TP
+.BR \-2 , " \-v"
+Make a Minix version 2 filesystem.
+.TP
+.B \-3
+Make a Minix version 3 filesystem.
+.TP
+\fB\-V\fR, \fB\-\-version\fR
+Display version information and exit. The long option cannot be combined
+with other options.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Display help text and exit.
+.SH "EXIT CODES"
+The exit code returned by
+.B mkfs.minix
+is one of the following:
+.IP 0
+No errors
+.IP 8
+Operational error
+.IP 16
+Usage or syntax error
+.SH "SEE ALSO"
+.BR fsck (8),
+.BR mkfs (8),
+.BR reboot (8)
+.SH AVAILABILITY
+The mkfs.minix command is part of the util-linux package and is available from
+https://www.kernel.org/pub/linux/utils/util-linux/.

+ *
+ * 28.02.92 - Added %-information when using -c.
+ *
+ * 28.02.93 - Added support for other namelengths than the original
+ * 14 characters so that I can test the new kernel routines..
+ *
+ * 09.10.93 - Make exit status conform to that required by fsutil
+ * (Rik Faith, faith@cs.unc.edu)
+ *
+ * 31.10.93 - Added inode request feature, for backup floppies: use
+ * 32 inodes, for a news partition use more.
+ * (Scott Heavner, sdh@po.cwru.edu)
+ *
+ * 03.01.94 - Added support for file system valid flag.

+.SH NAME
+mkswap \- set up a Linux swap area
+.SH SYNOPSIS
+.B mkswap
+[options]
+.I device
+.RI [ size ]
+.SH DESCRIPTION
+.B mkswap
+sets up a Linux swap area on a device or in a file.
+
+The
+.I device
+argument will usually be a disk partition (something like
+.IR /dev/sdb7 )
+but can also be a file.
+The Linux kernel does not look at partition IDs, but
+many installation scripts will assume that partitions
+of hex type 82 (LINUX_SWAP) are meant to be swap partitions.
+(\fBWarning: Solaris also uses this type. Be careful not to kill
+your Solaris partitions.\fP)
+
+The
+.I size
+parameter is superfluous but retained for backwards compatibility.
+(It specifies the desired size of the swap area in 1024-byte blocks.
+.B mkswap
+will use the entire partition or file if it is omitted.
+Specifying it is unwise \(en a typo may destroy your disk.)
+
+After creating the swap area, you need the
+.B swapon
+command to start using it. Usually swap areas are listed in
+.I /etc/fstab
+so that they can be taken into use at boot time by a
+.B swapon \-a
+command in some boot script.
+
+.SH WARNING
+The swap header does not touch the first block. A boot loader or disk label
+can be there, but it is not a recommended setup. The recommended setup is to
+use a separate partition for a Linux swap area.
+
+.BR mkswap ,
+like many others mkfs-like utils,
+.B erases the first partition block to make any previous filesystem invisible.
+
+However,
+.B mkswap
+refuses to erase the first block on a device with a disk
+label (SUN, BSD, \&...\&).
+
+.SH OPTIONS
+.TP
+.BR \-c , " \-\-check"
+Check the device (if it is a block device) for bad blocks
+before creating the swap area.
+If any bad blocks are found, the count is printed.
+.TP
+.BR \-f , " \-\-force"
+Go ahead even if the command is stupid.
+This allows the creation of a swap area larger than the file
+or partition it resides on.
+
+Also, without this option,
+.B mkswap
+will refuse to erase the first block on a device with a partition table.
+.TP
+.BR \-L , " \-\-label " \fIlabel\fR
+Specify a \fIlabel\fR for the device, to allow
+.B swapon
+by label.
+.TP
+.BR \-p , " \-\-pagesize " \fIsize\fR
+Specify the page \fIsize\fR (in bytes) to use. This option is usually unnecessary;
+.B mkswap

+.TP
+.BR \-U , " \-\-uuid " \fIUUID\fR

+Display version information and exit.
+
+.SH NOTES
+The maximum useful size of a swap area depends on the architecture and
+the kernel version.
+
+The maximum number of the pages that is possible to address by swap area header
+is 4294967295 (UINT_MAX). The remaining space on the swap device is ignored.
+
+Presently, Linux allows 32 swap areas.
+The areas in use can be seen in the file
+.I /proc/swaps
+
+.B mkswap
+refuses areas smaller than 10 pages.
+
+If you don't know the page size that your machine uses, you may be
+able to look it up with "cat /proc/cpuinfo" (or you may not \(en
+the contents of this file depend on architecture and kernel version).
+
+To set up a swap file, it is necessary to create that file before
+initializing it with
+.BR mkswap ,
+e.g.\& using a command like
+
+.nf
+.RS
+# dd if=/dev/zero of=swapfile bs=1MiB count=$((8*1024))
+.RE
+.fi
+
+to create 8GiB swapfile.
+
+Note that a swap file must not contain any holes. Using
+.BR cp (1)
+to create the file is not acceptable. Neither is use of
+.BR fallocate (1)
+on file systems that support preallocated files, such as
+.BR XFS " or " ext4 ,
+or on copy-on-write filesystems like
+.BR btrfs .
+It is recommended to use
+.BR dd (1)
+and /dev/zero in these cases. Please read notes from
+.BR swapon (8)
+before adding a swap file to copy-on-write filesystems.
+
+.SH ENVIRONMENT
+.IP LIBBLKID_DEBUG=all
+enables libblkid debug output.
+
+.SH "SEE ALSO"
+.BR fdisk (8),
+.BR swapon (8)
+.SH AVAILABILITY
+The mkswap command is part of the util-linux package and is available from
+https://www.kernel.org/pub/linux/utils/util-linux/.

+.SH NAME
+partx \- tell the kernel about the presence and numbering of on-disk partitions
+.SH SYNOPSIS
+.B partx

+.B partx
+.RB [ \-a | \-d | \-P | \-r | \-s | \-u ]
+.RB [ \-t " \fItype\fR]"
+.IR partition " [" disk ]
+.SH DESCRIPTION
+Given a device or disk-image,
+.B partx
+tries to parse the partition table and list its contents. It
+can also tell the kernel to add or remove partitions from its
+bookkeeping.
+.PP
+The
+.I disk
+argument is optional when a
+.I partition
+argument is provided. To force scanning a partition as if it were a whole disk
+(for example to list nested subpartitions), use the argument "\-" (hyphen-minus).
+For example:
+
+.RS 7
+.TP
+partx \-\-show \- /dev/sda3
+.RE
+.PP
+This will see sda3 as a whole-disk rather than as a partition.
+.PP
+.B partx is not an fdisk program
+\(en adding and removing partitions does not change the disk, it just
+tells the kernel about the presence and numbering of on-disk
+partitions.
+.SH OPTIONS
+.TP
+.BR \-a , " \-\-add"
+Add the specified partitions, or read the disk and add all partitions.
+.TP
+.BR \-b , " \-\-bytes"
+Print the SIZE column in bytes rather than in human-readable format.
+.TP
+.BR \-d , " \-\-delete"
+Delete the specified partitions or all partitions.
+.TP
+.BR \-g , " \-\-noheadings"
+Do not print a header line with \fB\-\-show\fR or \fB\-\-raw\fR.
+.TP
+.BR \-l , " \-\-list"
+List the partitions. Note that all numbers are in 512-byte sectors.
+This output format is DEPRECATED in favour of
+.BR \-\-show .
+Do not use it in newly written scripts.
+.TP
+.BR \-n , " \-\-nr " \fIM : \fIN
+Specify the range of partitions. For backward compatibility also the
+format \fIM\fB\-\fIN\fR is supported.
+The range may contain negative numbers, for example
+.B \-\-nr \-1:\-1
+means the last partition, and
+.B \-\-nr \-2:\-1
+means the last two partitions. Supported range specifications are:
+.RS 14
+.TP
+.I M
+Specifies just one partition (e.g.\& \fB\-\-nr 3\fR).
+.TP
+.IB M :
+Specifies the lower limit only (e.g.\& \fB\-\-nr 2:\fR).
+.TP
+.BI : N
+Specifies the upper limit only (e.g.\& \fB\-\-nr :4\fR).
+.TP
+.IB M : N
+Specifies the lower and upper limits (e.g.\& \fB\-\-nr 2:4\fR).
+.RE

+.TH RAW 8 "August 1999" "util-linux" "System Administration"
+.SH NAME
+raw \- bind a Linux raw character device
+.SH SYNOPSIS
+.B raw
+.I /dev/raw/raw<N> <major> <minor>
+.PP
+.B raw
+.I /dev/raw/raw<N> /dev/<blockdev>
+.PP
+.B raw \-q
+.I /dev/raw/raw<N>
+.PP
+.B raw \-qa
+.SH DESCRIPTION
+.B raw
+is used to bind a Linux raw character device to a block device. Any
+block device may be used: at the time of binding, the device driver does
+not even have to be accessible (it may be loaded on demand as a kernel
+module later).
+.PP
+.B raw
+is used in two modes: it either sets raw device bindings, or it queries
+existing bindings. When setting a raw device,
+.I /dev/raw/raw<N>
+is the device name of an existing raw device node in the filesystem.
+The block device to which it is to be bound can be specified either in
+terms of its
+.I major
+and
+.I minor
+device numbers, or as a path name
+.I /dev/<blockdev>
+to an existing block device file.
+.PP
+The bindings already in existence can be queried with the
+.I \-q
+option, which is used either with a raw device filename to query that one
+device, or with the
+.I \-a
+option to query all bound raw devices.
+.PP
+Unbinding can be done by specifying major and minor 0.
+.PP
+Once bound to a block device, a raw device can be opened, read and
+written, just like the block device it is bound to. However, the raw
+device does not behave exactly like the block device. In particular,
+access to the raw device bypasses the kernel's block buffer cache
+entirely: all I/O is done directly to and from the address space of the
+process performing the I/O. If the underlying block device driver can
+support DMA, then no data copying at all is required to complete the
+I/O.
+.PP
+Because raw I/O involves direct hardware access to a process's memory, a
+few extra restrictions must be observed. All I/Os must be correctly
+aligned in memory and on disk: they must start at a sector offset on
+disk, they must be an exact number of sectors long, and the data buffer
+in virtual memory must also be aligned to a multiple of the sector
+size. The sector size is 512 bytes for most devices.
+.SH OPTIONS
+.TP
+\fB\-q\fR, \fB\-\-query\fR
+Set query mode.
+.B raw
+will query an existing binding instead of setting a new one.
+.TP
+\fB\-a\fR, \fB\-\-all\fR
+With
+.B \-q
+, specify that all bound raw devices should be queried.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Display help text and exit.
+.TP
+\fB\-V\fR, \fB\-\-version\fR
+Display version information and exit.
+
+.SH BUGS
+The Linux
+.BR dd (1)
+command should be used without the \fBbs=\fR option, or the blocksize
+needs to be a multiple of the sector size of the device (512 bytes usually),
+otherwise it will fail with "Invalid Argument" messages (EINVAL).
+
+.PP
+Raw I/O devices do not maintain cache coherency with the Linux block
+device buffer cache. If you use raw I/O to overwrite data already in
+the buffer cache, the buffer cache will no longer correspond to the
+contents of the actual storage device underneath. This is deliberate,
+but is regarded either a bug or a feature depending on who you ask!
+.SH NOTES
+Rather than using raw devices applications should prefer
+.BR open (2)
+devices, such as /dev/sda1, with the O_DIRECT flag.
+.SH AUTHOR
+Stephen Tweedie (sct@redhat.com)
+.SH AVAILABILITY
+The raw command is part of the util-linux package and is available from
+https://www.kernel.org/pub/linux/utils/util-linux/.

+.SH NAME
+sfdisk \- display or manipulate a disk partition table
+.SH SYNOPSIS
+.B sfdisk
+[options]
+.I device
+.RB [ \-N
+.IR partition-number ]
+.sp
+.B sfdisk
+[options]
+.I command
+.SH DESCRIPTION
+.B sfdisk
+is a script-oriented tool for partitioning any block device.
+
+Since version 2.26
+.B sfdisk
+supports MBR (DOS), GPT, SUN and SGI disk labels, but no longer provides any
+functionality for CHS (Cylinder-Head-Sector) addressing. CHS has
+never been important for Linux, and this addressing concept does not make any
+sense for new devices.
+.sp
+.B sfdisk
+(since version 2.26)
+.B aligns the start and end of partitions
+to block-device I/O limits when relative sizes are specified, when the default
+values are used or when multiplicative suffixes (e.g. MiB) are used for sizes.
+It is possible that partition size will be optimized (reduced or enlarged) due
+to alignment if the start offset is specified exactly in sectors and partition
+size relative or by multiplicative suffixes.
+
+The recommended way is not to specify start offsets at all and specify
+partition size in MiB, GiB (or so). In this case sfdisk align all partitions
+to block-device I/O limits (or when I/O limits are too small then to megabyte
+boundary to keep disk layout portable). If this default behaviour is unwanted
+(usually for very small partitions) then specify offsets and sizes in
+sectors. In this case sfdisk entirely follows specified numbers without any
+optimization.
+.sp
+.B sfdisk
+does not create the standard system partitions for SGI and SUN disk labels like
+.BR fdisk (8)
+does.
+It is necessary to explicitly create all partitions including whole-disk system
+partitions.
+
+.B sfdisk
+uses BLKRRPART (reread partition table) ioctl to make sure that the device is
+not used by system or another tools (see also --no-reread). It's possible that
+this feature or another sfdisk activity races with \fBudevd\fR. The recommended way
+how to avoid possible collisions is to use exclusive flock for the whole-disk
+device to serialize device access. The exclusive lock will cause udevd to skip
+the event handling on the device. For example:
+.RS
+.sp
+.nf
+.B "flock /dev/sdc sfdisk /dev/sdc"
+.fi
+.sp
+.RE
+Note, this semantic is not currently supported by udevd for MD and DM devices.
+
+.SH COMMANDS
+The commands are mutually exclusive.
+.TP
+.RB [ \-N " \fIpartition-number\fR] " \fIdevice\fR
+The default \fBsfdisk\fR command is to read the specification for the desired
+partitioning of \fIdevice\fR from standard input, and then create a partition
+table according to the specification. See below for the description of the
+input format. If standard input is a terminal, then \fBsfdisk\fR starts an
+interactive session.
+.sp
+If the option \fB\-N\fR is specified, then the changes are applied to
+the partition addressed by \fIpartition-number\fR. The unspecified fields
+of the partition are not modified.
+.sp
+Note that it's possible to address an unused partition with \fB\-N\fR.
+For example, an MBR always contains 4 partitions, but the number of used
+partitions may be smaller. In this case \fBsfdisk\fR follows the default
+values from the partition table and does not use built-in defaults for the
+unused partition given with \fB\-N\fR. See also \fB\-\-append\fR.
+.TP
+.BR \-A , " \-\-activate \fIdevice " [ \fIpartition-number...]
+Switch on the bootable flag for the specified partitions and switch off the
+bootable flag on all unspecified partitions. The special placeholder '-'
+may be used instead of the partition numbers to switch off the bootable flag
+on all partitions.
+
+The activation command is supported for MBR and PMBR only. If GPT label is detected
+than sfdisk prints warning and automatically enter PMBR.
+
+If no \fIpartition-number\fR is specified, then list the partitions with an
+enabled flag.
+.TP
+.BR "\-\-delete \fIdevice " [ \fIpartition-number ...]
+Delete all or the specified partitions.
+.TP
+.BR \-d , " \-\-dump " \fIdevice\fR
+Dump the partitions of a device in a format that is usable as input to \fBsfdisk\fR.
+See the section \fBBACKING UP THE PARTITION TABLE\fR.
+.TP
+.BR \-g , " \-\-show\-geometry " [ \fIdevice ...]
+List the geometry of all or the specified devices. For backward
+compatibility the deprecated option \fB\-\-show\-pt\-geometry\fR have the same
+meaning as this one.
+.TP
+.BR \-J , " \-\-json " \fIdevice\fR
+Dump the partitions of a device in JSON format. Note that \fBsfdisk\fR is
+not able to use JSON as input format.
+.TP
+.BR \-l , " \-\-list " [ \fIdevice ...]
+List the partitions of all or the specified devices. This command can be used
+together with \fB\-\-verify\fR.
+.TP
+.BR \-F , " \-\-list-free " [ \fIdevice ...]
+List the free unpartitioned areas on all or the specified devices.
+.TP
+.BR "\-\-part\-attrs \fIdevice partition-number " [ \fIattributes ]
+Change the GPT partition attribute bits. If \fIattributes\fR is not specified,
+then print the current partition settings. The \fIattributes\fR argument is a
+comma- or space-delimited list of bits. The currently supported attribute
+bits are: RequiredPartition, NoBlockIOProtocol, LegacyBIOSBootable
+and GUID-specific bits in the range from 48 to 63. For example, the string
+"RequiredPartition,50,51" sets three bits.
+.TP
+.BR "\-\-part\-label \fIdevice partition-number " [ \fIlabel ]
+Change the GPT partition name (label). If \fIlabel\fR is not specified,
+then print the current partition label.
+.TP
+.BR "\-\-part\-type \fIdevice partition-number " [ \fItype ]
+Change the partition type. If \fItype\fR is not specified, then print the
+current partition type. The \fItype\fR argument is hexadecimal for MBR,
+or a GUID for GPT. For backward compatibility the options \fB\-c\fR and
+\fB\-\-id\fR have the same meaning as this one.
+.TP
+.BR "\-\-part\-uuid \fIdevice partition-number " [ \fIuuid ]
+Change the GPT partition UUID. If \fIuuid\fR is not specified,
+then print the current partition UUID.
+.TP
+.BR \-r , " \-\-reorder " \fIdevice
+Renumber the partitions, ordering them by their start offset.
+.TP
+.BR \-s , " \-\-show\-size " [ \fIdevice ...]
+List the sizes of all or the specified devices in units of 1024 byte size.
+This command is DEPRECATED in favour of
+.BR blockdev (1).
+.TP
+.BR \-T , " \-\-list\-types"
+Print all supported types for the current disk label or the label specified by
+\fB\-\-label\fR.
+.TP
+.BR \-V , " \-\-verify " [ \fIdevice ...]
+Test whether the partition table and partitions seem correct.
+
+.SH OPTIONS
+.TP
+.BR \-a , " \-\-append"
+Don't create a new partition table, but only append the specified partitions.
+.TP
+.BR \-b , " \-\-backup"
+Back up the current partition table sectors before starting the partitioning.
+The default backup file name is ~/sfdisk-<device>-<offset>.bak; to use another
+name see option \fB\-O\fR, \fB\-\-backup\-file\fR.
+.TP
+.BR \-\-color [ =\fIwhen ]
+Colorize the output. The optional argument \fIwhen\fP
+can be \fBauto\fR, \fBnever\fR or \fBalways\fR. If the \fIwhen\fR argument is omitted,
+it defaults to \fBauto\fR. The colors can be disabled; for the current built-in default
+see the \fB\-\-help\fR output. See also the \fBCOLORS\fR section.
+.TP
+.BR \-f , " \-\-force"
+Disable all consistency checking.
+.TP
+.B \-\-Linux
+Deprecated and ignored option. Partitioning that is compatible with
+Linux (and other modern operating systems) is the default.
+.TP
+.BR \-n , " \-\-no\-act"
+Do everything except writing to the device.
+.TP
+.B \-\-no\-reread
+Do not check through the re-read-partition-table ioctl whether the device is in use.
+.TP
+.B \-\-no\-tell\-kernel
+Don't tell the kernel about partition changes. This option is recommended together
+with \fB\-\-no\-reread\fR to modify a partition on used disk. The modified partition
+should not be used (e.g. mounted).
+.TP
+.BR \-O , " \-\-backup\-file " \fIpath
+Override the default backup file name. Note that the device name and offset
+are always appended to the file name.
+.TP
+.BR \-\-move-data [ =\fIpath ]
+Move data after partition relocation, for example when moving the beginning
+of a partition to another place on the disk. The size of the partition has
+to remain the same, the new and old location may overlap. This option requires
+option \fB\-N\fR in order to be processed on one specific partition only.
+
+The \fIpath\fR overrides the default log file name
+(the default is ~/sfdisk-<devname>.move). The log file contains information
+about all read/write operations on the partition data.
+
+Note that this operation is risky and not atomic. \fBDon't forget to backup your data!\fR
+
+In the example below, the first command creates a 100MiB free area before
+the first partition and moves the data it contains (e.g. a filesystem),
+the next command creates a new partition from the free space (at offset 2048),
+and the last command reorders partitions to match disk order
+(the original sdc1 will become sdc2).
+.RS
+.sp
+.B "echo '+100M,' | sfdisk --move-data /dev/sdc -N 1"
+.br
+.B "echo '2048,' | sfdisk /dev/sdc --append
+.br
+.B sfdisk /dev/sdc --reorder
+.sp
+.RE
+
+.TP
+.BR \-o , " \-\-output " \fIlist
+Specify which output columns to print. Use
+.B \-\-help
+to get a list of all supported columns.
+.sp
+The default list of columns may be extended if \fIlist\fP is
+specified in the format \fI+list\fP (e.g. \fB-o +UUID\fP).
+.TP
+.BR \-q , " \-\-quiet"
+Suppress extra info messages.
+.TP
+.BR \-u , " \-\-unit S"
+Deprecated option. Only the sector unit is supported. This option is not
+supported when using the --show-size command.
+.TP
+.BR \-X , " \-\-label " \fItype
+Specify the disk label type (e.g. \fBdos\fR, \fBgpt\fR, ...). If this option
+is not given, then \fBsfdisk\fR defaults to the existing label, but if there
+is no label on the device yet, then the type defaults to \fBdos\fR. The default
+or the current label may be overwritten by the "label: <name>" script header
+line. The option \fB\-\-label\fR does not force \fBsfdisk\fR to create empty
+disk label (see the \fBEMPTY DISK LABEL\fR section below).
+.TP
+.BR \-Y , " \-\-label\-nested " \fItype
+Force editing of a nested disk label. The primary disk label has to exist already.
+This option allows to edit for example a hybrid/protective MBR on devices with GPT.
+
+.TP
+.BR -w , " \-\-wipe "\fIwhen
+Wipe filesystem, RAID and partition-table signatures from the device, in order
+to avoid possible collisions. The argument \fIwhen\fR can be \fBauto\fR,
+\fBnever\fR or \fBalways\fR. When this option is not given, the default is
+\fBauto\fR, in which case signatures are wiped only when in interactive mode;
+except the old partition-table signatures which are always wiped before create
+a new partition-table if the argument \fIwhen\fR is not \fBnever\fR. In all

+.TP
+.B unit

+.TP
+.B label
+Specify the partition table type. For example \fBdos\fR or \fBgpt\fR.
+.TP
+.B label-id
+Specify the partition table identifier. It should be a hexadecimal number
+(with a 0x prefix) for MBR and a UUID for GPT.
+.TP

+.B last-lba
+Specify the last usable sector for GPT partitions.
+.TP
+.B table-length

+.sp
+.RE
+where each line fills one partition descriptor.
+.sp
+Fields are separated by whitespace, comma or semicolon possibly
+followed by whitespace; initial and trailing whitespace is ignored.
+Numbers can be octal, decimal or hexadecimal; decimal is the default.
+When a field is absent, empty or specified as '-' a default value is
+used. But when the \fB-N\fR option (change a single partition) is
+given, the default for each field is its previous value.
+.sp
+The default value of
+.I start
+is the first non-assigned sector aligned according to device I/O limits.
+The default start offset for the first partition is 1 MiB. The offset may
+be followed by the multiplicative suffixes (KiB, MiB, GiB, TiB, PiB,
+EiB, ZiB and YiB) then the number is interpreted as offset in bytes.
+.sp
+The default value of
+.I size
+indicates "as much as possible"; i.e. until the next partition or
+end-of-device. A numerical argument is by default interpreted as a
+number of sectors, however if the size is followed by one of the
+multiplicative suffixes (KiB, MiB, GiB, TiB, PiB, EiB, ZiB and YiB)
+then the number is interpreted as the size of the partition in bytes
+and it is then aligned according to the device I/O limits. A '+' can
+be used instead of a number to enlarge the partition as much as
+possible. Note '+' is equivalent to the default behaviour for a new
+partition; existing partitions will be resized as required.

+
+.SH "BACKING UP THE PARTITION TABLE"
+It is recommended to save the layout of your devices.
+.B sfdisk
+supports two ways.
+.sp
+Use the \fB\-\-dump\fR option to save a description of the device layout
+to a text file. The dump format is suitable for later \fBsfdisk\fR input.
+For example:
+.RS
+.sp
+.B "sfdisk --dump /dev/sda > sda.dump"
+.sp
+.RE
+This can later be restored by:
+.RS
+.sp
+.B "sfdisk /dev/sda < sda.dump"
+.RE
+
+If you want to do a full (binary) backup of all sectors where the
+partition table is stored,
+then use the \fB\-\-backup\fR option. It writes the sectors to
+~/sfdisk-<device>-<offset>.bak files. The default name of the backup file can
+be changed with the \fB\-\-backup\-file\fR option. The backup files
+contain only raw data from the \fIdevice\fR.
+Note that the same concept of backup files is used by
+.BR wipefs (8).
+For example:
+.RS
+.sp
+.B "sfdisk --backup /dev/sda"
+.sp
+.RE
+The GPT header can later be restored by:
+.RS
+.sp
+.nf
+.B "dd if=~/sfdisk-sda-0x00000200.bak of=/dev/sda \e"
+.B " seek=$((0x00000200)) bs=1 conv=notrunc"
+.fi
+.sp
+.RE
+Note that \fBsfdisk\fR since version 2.26 no longer provides the \fB\-I\fR option to
+restore sectors.
+.BR dd (1)
+provides all necessary functionality.
+
+.SH COLORS
+Implicit coloring can be disabled by an empty file \fI/etc/terminal-colors.d/sfdisk.disable\fR.
+
+See
+.BR terminal-colors.d (5)
+for more details about colorization configuration. The logical color names
+supported by
+.B sfdisk
+are:
+.TP
+.B header
+The header of the output tables.
+.TP
+.B warn
+The warning messages.
+.TP
+.B welcome
+The welcome message.
+
+.SH NOTES
+Since version 2.26 \fBsfdisk\fR no longer provides the \fB\-R\fR or
+\fB\-\-re\-read\fR option to force the kernel to reread the partition table.
+Use \fBblockdev \-\-rereadpt\fR instead.
+.PP
+Since version 2.26 \fBsfdisk\fR does not provide the \fB\-\-DOS\fR, \fB\-\-IBM\fR, \fB\-\-DOS\-extended\fR,
+\fB\-\-unhide\fR, \fB\-\-show\-extended\fR, \fB\-\-cylinders\fR, \fB\-\-heads\fR, \fB\-\-sectors\fR,

+.TH SWAPLABEL 8 "April 2010" "util-linux" "System Administration"
+.SH NAME
+swaplabel \- print or change the label or UUID of a swap area
+.SH SYNOPSIS
+.B swaplabel
+.RB [ \-L
+.IR label ]
+.RB [ \-U
+.IR UUID ]
+.I device
+.SH DESCRIPTION
+.B swaplabel
+will display or change the label or UUID of a swap partition located on
+.I device
+(or regular file).
+.PP
+If the optional arguments
+.B \-L
+and
+.B \-U
+are not given,
+.B swaplabel
+will simply display the current swap-area label and UUID of
+.IR device .
+.PP
+If an optional argument is present, then
+.B swaplabel
+will change the appropriate value on
+.IR device .
+These values can also be set during swap creation using
+.BR mkswap (8).
+The
+.B swaplabel
+utility allows to change the label or UUID on an actively used swap device.
+.SH OPTIONS
+.TP
+.BR \-h , " \-\-help"
+Display help text and exit.
+.TP
+.BR \-L , " \-\-label " \fIlabel\fR
+Specify a new \fIlabel\fR for the device.
+Swap partition labels can be at most 16 characters long. If
+.I label
+is longer than 16 characters,
+.B swaplabel
+will truncate it and print a warning message.
+.TP
+.BR \-U , " \-\-uuid " \fIUUID\fR
+Specify a new \fIUUID\fR for the device.
+The \fI UUID\fR
+must be in the standard 8-4-4-4-12 character format, such as is output by
+.BR uuidgen (1).
+.PP
+.SH AUTHOR
+.B swaplabel
+was written by Jason Borden <jborden@bluehost.com> and Karel Zak <kzak@redhat.com>.
+.SH ENVIRONMENT
+.IP LIBBLKID_DEBUG=all
+enables libblkid debug output.
+.SH AVAILABILITY
+The swaplabel command is part of the util-linux package and is available from
+https://www.kernel.org/pub/linux/utils/util-linux/.
+.SH SEE ALSO
+.BR uuidgen (1),
+.BR mkswap (8),
+.BR swapon (8)
