+.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.
