MOUNT_UDF(8)			   BSD System Manager's Manual			     MOUNT_UDF(8)

     mount_udf -- mount an UDF file system

     mount_udf [-c] [-g gid] [-o options] [-t gmtoff] [-s session] [-u uid] special node

     The mount_udf command attaches the UDF file system residing on the specified special device
     node on the location indicated with node.

     Anonymous files stored on the UDF disc will be represented and saved in the specified
     uid:gid pair.  If unspecified, it will default to nobody:nobody.  Both uid and gid can be
     either specified with their names as with their numerical equivalents.

     -c 	 Close the session after unmount creating remountable snapshots.  Closing a ses-
		 sion also allows -ROM devices to read the disc created.  Note that this option
		 only makes sense when mounting sequential recordable media like CD-R and DVD*R.

     -g gid	 Set the group of anonymous files on the file system.  The default group is the
		 nobody group.

     -o options  Use the specified mount options as specified in mount(8).

     -s session  Select the session session to be mounted instead of the default last one.
		 Implements readonly snapshots on sequential media.  Positive session values
		 indicate an absolute session number.  Negative session values are relative to
		 the last session found on the disc.  Note that this option only makes sense when
		 mounting sequential recordable media like CD-R and DVD*R.

     -t gmtoff	 Set the time zone offset (in seconds) from UTC to gmtoff, with positive values
		 indicating east of the Prime Meridian.  If not set, the user's current time zone
		 will be used.

     -u uid	 Set the owner of anonymous files on the file system.  The default owner is the
		 user nobody.

     UDF is a file system defined by the OSTA standardization group and is tailored for data
     interchange on optical discs (like CDs and DVDs) between different operating systems.  Its
     also more and more common on other media like Compact Flash (CF) cards.

     Read and write access is supported for all media types that CD/DVD type drives can recognise
     including DVD-RAM.  BluRay support is preliminary; read-only access should work fine but
     write support is experimental.

     Implemented and tested media types are CD-ROM, CD-R, CD-RW, CD-MRW, DVD-ROM, DVD*R, DVD*RW,
     DVD+MRW, DVD-RAM but the same code can also read HD-DVD and BluRay discs.	Discs created and
     written by UDFclient, Nero's InCD, and Roxio's DirectCD/Drag2Disc can be read without prob-
     lems.  Both open and closed media are supported so there is no need to close discs or ses-

     All current UDF versions up to version 2.60 are supported.

     Hard disk partitions and vnd(4) devices may also be mounted.  Note when mounting a vnd(4)
     device it might be necessary to specify the file image sector size in the geomspec when cre-
     ating the vnd(4) device or the disc sector size will be used.

     Write support for UDF version 2.50 is not completely mature and UDF version 2.01 should be
     used if possible; this is also the default format.

     Due to lack of test media and recording devices, BluRay support and in particular BluRay-R
     is still preliminary as of writing.
