NAME¶
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)
- cdr
- CD-R (CD Recordable)
- --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
- Make cdr media type closed (AVDP is written to start and also end of
disk). By default cdr media type is unclosed (AVDP is written only to
start of disk).
- --packetlen= length
- Packet length in number of sectors for cdrw (default: 32 sectors) and
dvdrw (default: 16 sectors) media types.
EXIT STATUS¶
mkudffs returns 0 if successful, non-zero if there are problems.
