mkudffs — create an UDF filesystem

Synopsis

mkudffs [ switches ] device [ blocks-count ]

Description

mkudffs is used to create a UDF filesystem on a device (usually a disk). device is the special file corresponding to the device (e.g /dev/hdX). blocks-count is the number of blocks on the device. If omitted, mkudffs automagically figures the file system size. The order of options matters. Ident string options must be first and options to override default settings implied by the media-type or UDF revison should be after the option they are overriding.

Options

-h,--help
Display the usage and list of options.
-l,--label= label
Specify the UDF label. UDF label is synonym for specifying both --lvid and --vid options. If omitted, mkudffs label is LinuxUDF.
-u,--uuid= uuid
Specify the UDF uuid. Must be exactly 16 characters and is used for first 16 characters of --fullvsid option. If omitted, mkudffs uuid is generated from local time and random number.
-b,--blocksize= block-size
Specify the size of blocks in bytes. Valid block size vales are 512, 1024, 2048 and 4096 bytes per block. If omitted, mkudffs block-size is set to device logical block (sector) size. If it is unknown then block-size 2048 is used.
-r,--udfrev= udf-revision
Specify the udf revision to use. Valid revisions are 0x0201, 0x0200, 0x0150, and 0x0102. If omitted, mkudffs udf-revision is 0x0201. The hex values represent the ISO/IEC 13346 standard version numbers: e.g. the 0x0201 refers to 2.01 (March 15, 2000) which is mainly a bugfix release to UDF 2.00.
--lvid= logical-volume-ident
Specify the logical volume identifier. If omitted, mkudffs logical-volume-ident is LinuxUDF.
--vid= volume-ident
Specify the volume identifier. If omitted, mkudffs volume-ident is LinuxUDF.
--vsid= volume-set-ident
Specify the 17.-127. character of volume set identifier. If omitted, mkudffs volume-set-ident is LinuxUDF.
--fsid= file-set-ident
Specify the file set identifier. If omitted, mkudffs file-set-ident is LinuxUDF.
--fullvsid= full-volume-set-ident
Specify the volume set identifier. Overwrite previous --uuid and --vsid options.
--uid= uid
Specify the uid of the root (/) directory. If omitted, mkudffs uid is 0.
--gid= gid
Specify the gid of the root (/) directory. If omitted, mkudffs gid is 0.
--strategy= strategy
Specify the allocation strategy to use. Valid strategies are 4 and 4096. If omitted, mkudffs strategy is based on the media-type.
--spartable= spartable-number
Specify the number of sparing tables to write to disc. Valid numbers are 1 - 4. This option implies --media-type=cdrw.
--media-type= media-type

Specify the media type. Valid media types are:

hd (default)
hard drive
dvd
DVD (Digital Versatile Disc)
dvdram
DVD-RAM (Digital Versatile Disc-Random Access Memory)
dvdrw
DVD-RW (DVD Read-Write)
worm
WORM (Write Once Ready Many)
mo
MO (Magneto Optical)
cdrw
CD-RW (CD Read-Write)
--space= space
freedbitmap
Freed bitmap
freedtable
Freed table
unallocbitmap
Unallocated bitmap
unalloctable
Unallocated table
--ad= ad
inicb
Allocation Descriptors in ICB
short
Short Allocation Descriptors
long
Long Allocation Descriptors
--noefe
Don't Use Extended File Entries
--u8
Ident string options are encoded in 8-bit OSTA Compressed Unicode equivalent. Must be specified as first argument.
--u16
Ident string options are encoded in 16-bit OSTA Compressed Unicode equivalent. Must be specified as first argument.
--utf8
Ident string options are encoded in UTF-8 (default). Must be specified as first argument.

--closed

--bridge

--packetlen= length
