DESCRIPTION

     The newfs_udf command builds the UDF filesystem on the specified special device.

     The options are as follows:

     General options:

     -N      Causes the file system parameters to be printed out without really creating the file system.

     -w      Stop processing on warnings, default: no

     --wipefs yes|no
	     Whether wipe existing file systems on the volume before formatting it.  Default: wipe existing file systems when media-type is block
	     device (blk), access-type is overwrite (ow), and the Keep Disc Open option (-o) is not specified; do not wipe existing file systems
	     by default in all other cases.

     --largesparse
	     Format the volume to use a non UDF-compliant format to efficiently support very large sparse files (up to 2^63 - 1, or
	     9,223,372,036,854,775,807 bytes).	Sparse files on this volume that has holes larger than 1GB cannot be accessed by other UDF imple-
	     mentations.

     Disc properties:

     -b block-size
	     The block size of the file system, in bytes, default: the native block size of the device, or 2048 for an image file

     -d      The file system manages defects by creating a sparable partition, default: no

     -e      Use extended file entry instead of file entry, default: no

     -E ecc-in-blks
	     ECC block size in number of blocks

     -m media-type
	     The type of the media, can be blk (block device), var-packet (varible size packet writing), fix-packet (fixed size packet writing),
	     or pow (pseudo overwrite), default: blk

     -t access-type
	     The access type of the partition, can be wo (writeonce), ow (overwrite), or pow (pseudo overwrite), default: ow

     -o      Keep the disc as open by only writing the first AVDP (e.g., background formating haven't finish, so the write of the last two AVDPs
	     is not possible), default: close the disc for overwrite media, and keep it open for write once media

     -p packet-size
	     The size of a packet in number of blocks, default: 1

     -s size
	     Size of the file system in blocks, default: size of the device

     UDF parameters:

     General:

     -r rev  UDF version number, can be 1.02, 1.50, 2.00, 2.01, 2.50, or 2.60, default: 2.01

     -u      Creates unique id table (or unique id stream), default: no

     --unalloc-spc blk-addr num-blks
	     Unallocated space recorded in unallocated space descriptor, default: no unallocated spc

     -v vol-name
	     Volume identifier, max 127 ascii or 63 unicode chars, default: "Untitled UDF Volume"

     --enc encoding-name
	     The character encoding of the volume name, can be "utf8" or "utf16", default: utf8

     Virtual partitions (for CD-R, DVD-R SL/DL, DVD+R SL/DL, and HD DVD-R SL/DL):

     -S start-block-address
	     The start block address of the last session.  Newfs_udf will search for this value for optical media

     Sparable partitions (for CD-RW, DVD-RW, and DVD+RW):

     --spare-blks n
	     Total number of sparing blocks (2 sparing tables are always used), default: 128

     -D defect-file-name
	     The name of the file containing all defect blocks.  This file is a text file, contains the physical block address of the media that
	     has defects.  When one block of a packet is defective, the whole packet is marked as defective.  The block numbers in the file is
	     delimited by space.  Multiple numbers can be on the same line.

     Metadata partitions (for BD-R with POW, BD-RE and other overwritable media with UDF 2.50 or higher ):

     --dup-meta-part-file
	     Duplicate the content of the metadata file in the metadata mirror file, default: no

     --meta-part-alloc-unit n
	     The allocation unit size of the metadata partition in number of blocks, default: max(32, eccSizeInBlks, packetSize)

     --meta-part-align-unit n
	     The alignment unit size of the metadata partition in number of blocks, default: max(eccSizeInBlks, packetSize)

     --meta-part-init-size n
	     The initial size of the metadata partition in number of blocks, default: 32

     --userid uid
	     or

     -U uid  Use the specified uid (numeric value only) as the owner of the root directory.

     --groupid gid
	     or

     -G gid  Use the specified gid (numeric value only) as the group of the root directory.
