.Nm

.\".Op Fl c
|
||||
.Op Fl g Ar gid
|
||||
.Op Fl o Ar options
|
||||
.Op Fl t Ar gmtoff
|

.Pa special
|
||||
.Pa node
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
command attaches the UDF file system residing on the specified
|
||||
.Pa special
|
||||
device node on the location indicated with
|
||||
.Pa node .
|
||||
.Pp
|
||||
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.
|
||||
.Bl -tag -width XXXoptions
|
||||
.\" -c flag specifies closure of CD/DVD session after dismount (writing)
|
||||
.It Fl g Ar gid
|
||||
Set the group of anonymous files on the file system. The default group is the
|
||||
nobody group.
|
||||
.It Fl o Ar options
|
||||
Use the specified mount
|
||||
.Ar options
|
||||
as specified in
|
||||
.Xr mount 8 .
|
||||
.It Fl s Ar session
|
||||
Select the session
|
||||
.Ar session
|
||||
to be mounted instead of the default last one. Positive
|
||||
.Ar session
|
||||
values indicate an absolute session number. Negative
|
||||
.Ar session
|
||||
values are relative to the last lession found on the disc.
|
||||
Note that this option only makes sense when mounting sequential recordable
|
||||
media like CD-R and DVD*R.
|
||||
.It Fl t Ar gmtoff
|
||||
Set the time zone offset (in seconds) from UTC to
|
||||
.Ar gmtoff .
|
||||
with positive values indicating east of the Prime Meridian.
|
||||
If not set, the user's current time zone will be used.
|
||||
.It Fl u Ar uid
|
||||
Set the owner of anonymous files on the file system. The default owner is the
|
||||
user nobody.

|
||||
.Sh NOTES
|
||||
UDF is a file system defined by the OSTA standardisation 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.
|
||||
.Pp
|
||||
Currently only read access is supported to all media types that CD/DVD type
|
||||
drives can recognize including DVD-RAM and BlueRay drives. Write access is
|
||||
planned and in preparation.
|
||||
.Pp
|
||||
Implemented and tested media types are CD-ROM, CD-R, CD-RW, CD-MRW, DVD-ROM,
|
||||
DVD*R, DVD*RW, DVD+MRW but the same code can also read DVD-RAM, HD-DVD and
|
||||
BluRay discs. Discs created and written by UDFclient, Nero's InCD and Roxio's
|
||||
DirectCD/Drag2Disc read fine. Both open and closed media are supported so
|
||||
there is no need to close discs or close sessions.
|
||||
.Pp
|
||||
Support for harddisc partitions and optionally for files (like using vnd) is
|
||||
not implemented yet.
|
||||
.Pp
|
||||
All current UDF versions upto version 2.60 are supported.
|
||||
.Sh BUGS
|
||||
Due to lack of test media version 2.50 and 2.60 are prepared though not
|
||||
implemented and tested yet.
