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.
