.Sh DESCRIPTION
The
.Nm
utility attaches the NTFS filesystem residing on the device
.Pa special
to the global filesystem namespace at the location
indicated by
.Pa node .
This command is normally executed by
.Xr mount 8
at boot time, but can be used by any user to mount an
NTFS filesystem on any directory that they own (provided,
of course, that they have appropriate access to the device that
contains the filesystem).
.Pp
The options are as follows:
.Bl -tag -width Ds
.It Fl a
Force behaviour to return MS-DOS 8.3 names also on
.Fn readdir .
.It Fl i
Make name lookup case insensitive for all names except POSIX names.
.It Fl u Ar uid
Set the owner of the files in the filesystem to
.Ar uid .
The default owner is the owner of the directory
on which the filesystem is being mounted.
.It Fl g Ar gid
Set the group of the files in the filesystem to
.Ar gid .
The default group is the group of the directory
on which the filesystem is being mounted.
.It Fl m Ar mask
Specify the maximum file permissions for files
in the filesystem.
.It Fl W Ar u2wtable
Specify
.Ux
to
.Tn Unicode
translation table.
See
.Xr mount_msdosfs 8
for the description of this option.
.El
.Sh FEATURES

.Sq ATTRNAME
is an attribute name.
Default is none.
.Sh EXAMPLES
To mount an ntfs volume located in
.Pa /dev/ad1s1 :
.Bd -literal -offset indent
# mount_ntfs /dev/ad1s1 /mnt
.Ed
.Pp
To get the volume name (in Unicode):
.Bd -literal -offset indent
# cat /mnt/\\$Volume:\\$VOLUME_NAME
.Ed
.Pp
To read directory raw data:
.Bd -literal -offset indent
# cat /mnt/foodir:\\$INDEX_ROOT:\\$I30
.Ed

Limitations: file must be nonresident
and must not contain any sparces (uninitialized areas); compressed
files are also not supported.
