  24 == NAME
  25
  26 sfdisk - display or manipulate a disk partition table
  27
  28 == SYNOPSIS
  29
  30 *sfdisk* [options] _device_ [*-N* _partition-number_]
  31
  32 *sfdisk* [options] _command_
  33
  34 == DESCRIPTION
  35
  36 *sfdisk* is a script-oriented tool for partitioning any block device. It runs in interactive mode if executed on a terminal (stdin refers to a terminal).
  37
  38 Since version 2.26 *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.
  39
  40 *sfdisk* protects the first disk sector when create a new disk label. The option *--wipe always* disables this protection. Note that *fdisk*(8) and *cfdisk*(8) completely erase this area by default.
  41
  42 *sfdisk* (since version 2.26) *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.
  43
  44 The recommended way is not to specify start offsets at all and specify partition size in MiB, GiB (or so). In this case *sfdisk* aligns 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.
  45
  46 *sfdisk* does not create the standard system partitions for SGI and SUN disk labels like *fdisk*(8) does. It is necessary to explicitly create all partitions including whole-disk system partitions.
  47
  48 *sfdisk* uses *BLKRRPART* (reread partition table) ioctl to make sure that the device is not used by system or other tools (see also *--no-reread*). It's possible that this feature or another *sfdisk* activity races with *systemd-udevd*(8). The recommended way how to avoid possible collisions is to use *--lock* option. The exclusive lock will cause *systemd-udevd* to skip the event handling on the device.
  49
  50 The *sfdisk* prompt is only a hint for users and a displayed partition number does not mean that the same partition table entry will be created (if *-N* not specified), especially for tables with gaps.
  51
  52 == COMMANDS
  53
  54 The commands are mutually exclusive.
  55
  56 [*-N* _partition-number_] __device__::
  57 The default *sfdisk* command is to read the specification for the desired partitioning of _device_ 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 *sfdisk* starts an interactive session.
  58 +
  59 If the option *-N* is specified, then the changes are applied to the partition addressed by _partition-number_. The unspecified fields of the partition are not modified.
  60 +
  61 Note that it's possible to address an unused partition with *-N*. For example, an MBR always contains 4 partitions, but the number of used partitions may be smaller. In this case *sfdisk* follows the default values from the partition table and does not use built-in defaults for the unused partition given with *-N*. See also *--append*.
  62
  63 *-A*, *--activate* __device__ [__partition-number__...]::
  64 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.
  65 +
  66 The activation command is supported for MBR and PMBR only. If a GPT label is detected, then *sfdisk* prints warning and automatically enters PMBR.
  67 +
  68 If no _partition-number_ is specified, then list the partitions with an enabled flag.
  69
  70 *--backup-pt-sectors* _device_::
  71 Back up the current partition table sectors in binary format and exit. See the *BACKING UP THE PARTITION TABLE* section.
  72
  73 *--delete* _device_ [__partition-number__...]::
  74 Delete all or the specified partitions.
  75
  76 *-d*, *--dump* _device_::
  77 Dump the partitions of a device in a format that is usable as input to *sfdisk*. See the *BACKING UP THE PARTITION TABLE* section.
  78
  79 *-g*, *--show-geometry* [__device__...]::
  80 List the geometry of all or the specified devices. For backward compatibility the deprecated option *--show-pt-geometry* have the same meaning as this one.
  81
  82 *-J*, *--json* _device_::
  83 Dump the partitions of a device in JSON format. Note that *sfdisk* is not able to use JSON as input format.
  84
  85 *-l*, *--list* [__device__...]::
  86 List the partitions of all or the specified devices. This command can be used together with *--verify*.
  87
  88 *-F*, *--list-free* [__device__...]::
  89 List the free unpartitioned areas on all or the specified devices.
  90
  91 *--part-attrs* _device partition-number_ [__attributes__]::
  92 Change the GPT partition attribute bits. If _attributes_ is not specified, then print the current partition settings. The _attributes_ argument is a comma- or space-delimited list of bits numbers or bit names. For example, the string "RequiredPartition,50,51" sets three bits. The currently supported attribute bits are:
  93 +
  94 *Bit 0 (RequiredPartition)*;;
  95 If this bit is set, the partition is required for the platform to function. The creator of the partition indicates that deletion or modification of the contents can result in loss of platform features or failure for the platform to boot or operate. The system cannot function normally if this partition is removed, and it should be considered part of the hardware of the system.
  96 *Bit 1 (NoBlockIOProtocol)*;;
  97 EFI firmware should ignore the content of the partition and not try to read from it.
  98 *Bit 2 (LegacyBIOSBootable)*;;
  99 The partition may be bootable by legacy BIOS firmware.
 100 *Bits 3-47*;;
 101 Undefined and must be zero. Reserved for expansion by future versions of the UEFI specification.
 102 *Bits 48-63*;;
 103 Reserved for GUID specific use. The use of these bits will vary depending on the partition type. For example Microsoft uses bit 60 to indicate read-only, 61 for shadow copy of another partition, 62 for hidden partitions and 63 to disable automount.
 104
 105 *--part-label* _device partition-number_ [__label__]::
 106 Change the GPT partition name (label). If _label_ is not specified, then print the current partition label.
 107
 108 *--part-type* _device partition-number_ [__type__]::
 109 Change the partition type. If _type_ is not specified, then print the current partition type.
 110 +
 111 The _type_ argument is hexadecimal for MBR, GUID for GPT, type alias (e.g. "linux") or type shortcut (e.g. 'L'). For backward compatibility the options *-c* and *--id* have the same meaning as this one.
 112
 113 *--part-uuid* _device partition-number_ [__uuid__]::
 114 Change the GPT partition UUID. If _uuid_ is not specified, then print the current partition UUID.
 115
 116 *--disk-id* _device_ [__id__]::
 117 Change the disk identifier. If _id_ is not specified, then print the current identifier. The identifier is UUID for GPT or unsigned integer for MBR.
 118
 119 *-r*, *--reorder* _device_::
 120 Renumber the partitions, ordering them by their start offset.
 121
 122 *-s*, *--show-size* [__device__...]::
 123 List the sizes of all or the specified devices in units of 1024 byte size. This command is DEPRECATED in favour of *blockdev*(8).
 124
 125 *-T*, *--list-types*::
 126 Print all supported types for the current disk label or the label specified by *--label*.
 127
 128 *-V*, *--verify* [__device__...]::
 129 Test whether the partition table and partitions seem correct.
 130
 131 *--relocate* _oper_ _device_::
 132 Relocate partition table header. This command is currently supported for GPT header only. The argument _oper_ can be:
 133 +
 134 *gpt-bak-std*;;
 135 Move GPT backup header to the standard location at the end of the device.
 136 *gpt-bak-mini*;;
 137 Move GPT backup header behind the last partition. Note that UEFI standard requires the backup header at the end of the device and partitioning tools can automatically relocate the header to follow the standard.
 138
 139 == OPTIONS
 140
 141 *-a*, *--append*::
 142 Don't create a new partition table, but only append the specified partitions.
 143 +
 144 Note that unused partition maybe be re-used in this case although it is not the last partition in the partition table. See also *-N* to specify entry in the partition table.
 145
 146 *-b*, *--backup*::
 147 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 *-O*, *--backup-file*. See section *BACKING UP THE PARTITION TABLE* for more details.
 148
 149 *--color*[**=**__when__]::
 150 Colorize the output. The optional argument _when_ can be *auto*, *never* or *always*. If the _when_ argument is omitted, it defaults to *auto*. The colors can be disabled; for the current built-in default see the *--help* output. See also the *COLORS* section.
 151
 152 *-f*, *--force*::
 153 Disable all consistency checking.
 154
 155 *--Linux*::
 156 Deprecated and ignored option. Partitioning that is compatible with Linux (and other modern operating systems) is the default.
 157
 158 *--lock*[=_mode_]::
 159 Use exclusive BSD lock for device or file it operates. The optional argument _mode_ can be *yes*, *no* (or 1 and 0) or *nonblock*. If the _mode_ argument is omitted, it defaults to *yes*. This option overwrites environment variable *$LOCK_BLOCK_DEVICE*. The default is not to use any lock at all, but it's recommended to avoid collisions with *systemd-udevd*(8) or other tools.
 160
 161 *-n*, *--no-act*::
 162 Do everything except writing to the device.
 163
 164 *--no-reread*::
 165 Do not check through the re-read-partition-table ioctl whether the device is in use.
 166
 167 *--no-tell-kernel*::
 168 Don't tell the kernel about partition changes. This option is recommended together with *--no-reread* to modify a partition on used disk. The modified partition should not be used (e.g., mounted).
 169
 170 *-O*, *--backup-file* _path_::
 171 Override the default backup file name. Note that the device name and offset are always appended to the file name.
 172
 173 *--move-data*[**=**__path__]::
 174 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 *-N* in order to be processed on one specific partition only.
 175 +
 176 The optional _path_ specifies log file name. The log file contains information about all read/write operations on the partition data. The word "@default" as a _path_ forces *sfdisk* to use _~/sfdisk-<devname>.move_ for the log. The log is optional since v2.35.
 177 +
 178 Note that this operation is risky and not atomic. *Don't forget to backup your data!*
 179 +
 180 See also *--move-use-fsync*.
 181 +
 182 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).
 183 +
 184 ____
 185 *echo '+100M,' | sfdisk --move-data /dev/sdc -N 1*
 186
 187 *echo '2048,' | sfdisk /dev/sdc --append*
 188
 189 *sfdisk /dev/sdc --reorder*
 190 ____
 191
 192 *--move-use-fsync*::
 193 Use the *fsync*(2) system call after each write when moving data to a new location by *--move-data*.
 194
 195 *-o*, *--output* _list_::
 196 Specify which output columns to print. Use *--help* to get a list of all supported columns.
 197 +
 198 The default list of columns may be extended if _list_ is specified in the format _{plus}list_ (e.g., *-o +UUID*).
 199 //TRANSLATORS: Keep {plus} untranslated.
 200
 201 *-q*, *--quiet*::
 202 Suppress extra info messages.
 203
 204 *-u*, *--unit S*::
 205 Deprecated option. Only the sector unit is supported. This option is not supported when using the *--show-size* command.
 206
 207 *-X*, *--label* _type_::
 208 Specify the disk label type (e.g., *dos*, *gpt*, ...). If this option is not given, then *sfdisk* defaults to the existing label, but if there is no label on the device yet, then the type defaults to *dos*. The default or the current label may be overwritten by the "label: <name>" script header line. The option *--label* does not force *sfdisk* to create empty disk label (see the *EMPTY DISK LABEL* section below).
 209
 210 *-Y*, *--label-nested* _type_::
 211 Force editing of a nested disk label. The primary disk label has to exist already. This option allows editing for example a hybrid/protective MBR on devices with GPT.
 212
 213 *-w*, *--wipe* _when_::
 214 Wipe filesystem, RAID and partition-table signatures from the device, in order to avoid possible collisions. The argument _when_ can be *auto*, *never* or *always*. When this option is not given, the default is *auto*, 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 _when_ is not *never*. The *auto* mode also does not wipe the first sector (boot sector), it is necessary to use the *always* mode to wipe this area. In all cases detected signatures are reported by warning messages before a new partition table is created. See also the *wipefs*(8) command.
 215
 216 *-W*, *--wipe-partitions* _when_::
 217 Wipe filesystem, RAID and partition-table signatures from a newly created partition, in order to avoid possible collisions. The argument _when_ can be *auto*, *never* or *always*. When this option is not given, the default is *auto*, 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 after a new partition is created. See also *wipefs*(8) command.
 218
 219 *-v*, *--version*::
 220 Display version information and exit.
 221
 222 *-h*, *--help*::
 223 Display help text and exit.
 224
 225 == INPUT FORMATS
 226
 227 *sfdisk* supports two input formats and generic header lines.
 228
 229 === Header lines
 230
 231 The optional header lines specify generic information that apply to the partition table. The header-line format is:
 232
 233 *<name>: <value>*
 234
 235 The currently recognized headers are:
 236
 237 *unit*::
 238 Specify the partitioning unit. The only supported unit is *sectors*.
 239 *label*::
 240 Specify the partition table type. For example *dos* or *gpt*.
 241 *label-id*::
 242 Specify the partition table identifier. It should be a hexadecimal number (with a 0x prefix) for MBR and a UUID for GPT.
 243 *first-lba*::
 244 Specify the first usable sector for GPT partitions. This header is ignored if the script and device sector size differ. In this case *sfdisk* uses label specific default.
 245 *last-lba*::
 246 Specify the last usable sector for GPT partitions. This header is ignored if the script and device sector size differ. In this case *sfdisk* uses label specific default.
 247 *table-length*::
 248 Specify the maximal number of GPT partitions.
 249 *grain*::
 250 Specify minimal size in bytes used to calculate partitions alignment. The default is 1MiB and it's strongly recommended to use the default. Do not modify this variable if you're not sure.
 251 *sector-size*::
 252 Specify sector size. *sfdisk* always uses device sector size. Since version 2.39 *sfdisk* recalculates sizes from dump if the script and device sector size differ.
 253
 254 Note that it is only possible to use header lines before the first partition is specified in the input.
 255
 256 === Unnamed-fields format
 257
 258 ____
 259 _start size type bootable_
 260 ____
 261
 262 where each line fills one partition descriptor.
 263
 264 Fields are separated by whitespace, comma (recommended) 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 *-N* option (change a single partition) is given, the default for each field is its previous value.
 265
 266 The default value of _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. If the offset is followed by the multiplicative suffixes (KiB, MiB, GiB, TiB, PiB, EiB, ZiB and YiB), then the number is interpreted as offset in bytes. Since v2.38 when the *-N* option (change a single partition) is given, a '{plus}' can be used to enlarge partition by move start of the partition if there is a free space before the partition.
 267
 268 //TRANSLATORS: Keep {plus} untranslated.
 269 The default value of _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 '{plus}' can be used instead of a number to enlarge the partition as much as possible. Note '{plus}' is equivalent to the default behaviour for a new partition; existing partitions will be resized as required.
 270
 271 The partition _type_ is given in hex for MBR (DOS) where 0x prefix is optional; a GUID string for GPT; a shortcut or an alias. It's recommended to use two letters for MBR hex codes to avoid collision between deprecated shortcut 'E' and '0E' MBR hex code. For backward compatibility *sfdisk* tries to interpret _type_ as a shortcut as a first possibility in partitioning scripts although on other places (e.g. *--part-type* command) it tries shortcuts as the last possibility.
 272
 273 Since v2.36 libfdisk supports partition type aliases as extension to shortcuts. The alias is a simple human readable word (e.g. "linux").
 274
 275 Since v2.37 libfdisk supports partition type names on input, ignoring the case of the characters and all non-alphanumeric and non-digit characters in the name (e.g. "Linux /usr x86" is the same as "linux usr-x86").
 276
 277 Supported shortcuts and aliases:
 278
 279 *L - alias 'linux'*::
 280 Linux; means 83 for MBR and 0FC63DAF-8483-4772-8E79-3D69D8477DE4 for GPT.
 281
 282 *S - alias 'swap'*::
 283 swap area; means 82 for MBR and 0657FD6D-A4AB-43C4-84E5-0933C84B4F4F for GPT
 284
 285 *Ex - alias 'extended'*::
 286 MBR extended partition; means 05 for MBR. The original shortcut 'E' is deprecated due to collision with 0x0E MBR partition type.
 287
 288 *H - alias 'home'*::
 289 home partition; means 933AC7E1-2EB4-4F13-B844-0E14E2AEF915 for GPT
 290
 291 *U - alias 'uefi'*::
 292 EFI System partition, means EF for MBR and C12A7328-F81F-11D2-BA4B-00A0C93EC93B for GPT
 293
 294 *R - alias 'raid'*::
 295 Linux RAID; means FD for MBR and A19D880F-05FC-4D3B-A006-743F0F84911E for GPT
 296
 297 *V - alias 'lvm'*::
 298 LVM; means 8E for MBR and E6D6D379-F507-44C2-A23C-238F2A3DF928 for GPT
 299
 300 The default _type_ value is _linux_.
 301
 302 The shortcut 'X' for Linux extended partition (85) is deprecated in favour of 'Ex'.
 303
 304 // TRANSLATORS: Keep {asterisk} untranslated.
 305 _bootable_ is specified as [*{asterisk}*|*-*], with as default not-bootable. The value of this field is irrelevant for Linux - when Linux runs it has been booted already - but it might play a role for certain boot loaders and for other operating systems.
 306
 307 === Named-fields format
 308
 309 This format is more readable, robust, extensible and allows specifying additional information (e.g., a UUID). It is recommended to use this format to keep your scripts more readable.
 310
 311 ____
 312 [_device_ *:*] _name_[**=**__value__], ...
 313 ____
 314
 315 The _device_ field is optional. *sfdisk* extracts the partition number from the device name. It allows specifying the partitions in random order. This functionality is mostly used by *--dump*. Don't use it if you are not sure.
 316
 317 The _value_ can be between quotation marks (e.g., name="This is partition name"). The fields *start=* and *size=* support '{plus}' and '-' in the same way as *Unnamed-fields format*.
 318
 319 The currently supported fields are:
 320
 321 **start=**__number__::
 322 The first non-assigned sector aligned according to device I/O limits. The default start offset for the first partition is 1 MiB. If the offset is followed by the multiplicative suffixes (KiB, MiB, GiB, TiB, PiB, EiB, ZiB and YiB), then the number is interpreted as offset in bytes.
 323
 324 **size=**__number__::
 325 Specify the partition size in sectors. The number may be followed by the multiplicative suffixes (KiB, MiB, GiB, TiB, PiB, EiB, ZiB and YiB), then it's interpreted as size in bytes and the size is aligned according to device I/O limits.
 326
 327 *bootable*::
 328 Mark the partition as bootable.
 329
 330 **attrs=**__string__::
 331 Partition attributes, usually GPT partition attribute bits. See *--part-attrs* for more details about the GPT-bits string format.
 332
 333 **uuid=**__string__::
 334 GPT partition UUID.
 335
 336 **name=**__string__::
 337 GPT partition name.
 338
 339 **type=**__code__::
 340 A hexadecimal number (without 0x) for an MBR partition, a GUID for a GPT partition, a shortcut as for unnamed-fields format or a type name (e.g. type="Linux /usr (x86)"). See above the section about the unnamed-fields format for more details. For backward compatibility the *Id=* field has the same meaning.
 341
 342 == EMPTY DISK LABEL
 343
 344 *sfdisk* does not create partition table without partitions by default. The lines with partitions are expected in the script by default. The empty partition table has to be explicitly requested by "label: <name>" script header line without any partitions lines. For example:
 345
 346 ____
 347 *echo 'label: gpt' | sfdisk /dev/sdb*
 348 ____
 349
 350 creates empty GPT partition table. Note that the *--append* disables this feature.
 351
 352 == BACKING UP THE PARTITION TABLE
 353
 354 It is recommended to save the layout of your devices. *sfdisk* supports two ways.
 355
 356 === Dump in sfdisk compatible format
 357
 358 Use the *--dump* command to save a description of the device layout to a text file.
 359 The dump format is suitable for later *sfdisk* input. For example:
 360 ____
 361 *sfdisk --dump /dev/sda > sda.dump*
 362 ____
 363
 364 This can later be restored by:
 365 ____
 366 *sfdisk /dev/sda < sda.dump*
 367 ____
 368
 369 === Full binary backup
 370
 371 If you want to do a full binary backup of all sectors where the partition table is stored, then use the *--backup-pt-sectors* command. It writes the sectors to _~/sfdisk-<device>-<offset>.bak_ files. The default name of the backup file can be changed with the *--backup-file* option. The backup files contain only raw data from the _device_. For example:
 372
 373 ____
 374 *sfdisk --backup-pt-sectors /dev/sda*
 375 ____
 376
 377 The GPT header can later be restored by:
 378
 379 ____
 380 *dd if=~/sfdisk-sda-0x00000200.bak of=/dev/sda seek=$\((0x00000200)) bs=1 conv=notrunc*
 381 ____
 382
 383
 384 It's also possible to use the *--backup* option to create the same backup immediately after startup for other *sfdisk* commands. For example, backup partition table before deleting all partitions from partition table:
 385 ____
 386 *sfdisk --backup --delete /dev/sda*
 387 ____

 390 The same concept of backup files is used by *wipefs*(8).
 391
 392 Note that *sfdisk* since version 2.26 no longer provides the *-I* option to restore sectors. *dd*(1) provides all necessary functionality.

 396 The logical color names supported by *sfdisk* are:
 397
 398 *header*::
 399 The header of the output tables.
 400 *warn*::
 401 The warning messages.
 402 *welcome*::
 403 The welcome message.

 405 == ENVIRONMENT
 406
 407 *SFDISK_DEBUG*=all::
 408 enables *sfdisk* debug output.
 409 *LIBFDISK_DEBUG*=all::
 410 enables libfdisk debug output.
 411 *LIBBLKID_DEBUG*=all::
 412 enables libblkid debug output.
 413 *LIBSMARTCOLS_DEBUG*=all::
 414 enables libsmartcols debug output.
 415 *LOCK_BLOCK_DEVICE*=<mode>::
 416 use exclusive BSD lock. The mode is "1" or "0". See *--lock* for more details.
 417
 418 == NOTES
 419
 420 Since version 2.26 *sfdisk* no longer provides the *-R* or *--re-read* option to force the kernel to reread the partition table. Use *blockdev --rereadpt* instead.
 421
 422 Since version 2.26 *sfdisk* does not provide the *--DOS*, *--IBM*, *--DOS-extended*, *--unhide*, *--show-extended*, *--cylinders*, *--heads*, *--sectors*, *--inside-outer*, *--not-inside-outer* options.
 423
 424 == EXAMPLES
 425
 426 *sfdisk --list --label-nested=mbr /dev/sda*::
 427 Print protective MBR on device with GPT disk label.
 428
 429 *echo -e ',10M,L\n,10M,L\n,+,\n' | sfdisk /dev/sdc*::
 430 Create three Linux partitions, with the default start, the size of the first two partitions is 10MiB, and the last partition fills all available space on the device.
 431
 432 *echo -e 'size=10M, type=L\n size=10M, type=L\n size=+\n' | sfdisk /dev/sdc*::
 433 The same as the previous example, but in named-fields format.
 434
 435 *echo -e 'type=swap' | sfdisk -N 3 /dev/sdc*::
 436 Set type of the 3rd partition to 'swap'.
 437
 438 *sfdisk --part-type /dev/sdc 3 swap*::
 439 The same as the previous example, but without script use.
 440
 441 *sfdisk --delete /dev/sdc 2*::
 442 Delete 2nd partition.
 443
 444 *echo "\+,+" | sfdisk -N 3 --move-data /dev/sdc*::
 445 Enlarge 3rd partition in both directions, move start to use free space before the partition and enlarge the size to use all free space after to the partition, and move partition data too.
