.Sh DESCRIPTION
The
.Nm
command attaches the MS-DOS filesystem residing on
the device

a special
to the global filesystem namespace at the location
indicated by

a node .
This command is normally executed by
.Xr mount 8
at boot time, but can be used by any user to mount an
MS-DOS file system on any directory that they own (provided,
of course, that they have appropriate access to the device that
contains the file system).

p
The options are as follows:
l -tag -width Ds t Fl o Ar options Use the specified mount
.Ar options ,
as described in
.Xr mount 8 .
t Fl u Ar uid Set the owner of the files in the file system to
.Ar uid .
The default owner is the owner of the directory
on which the file system is being mounted.
t Fl g Ar gid Set the group of the files in the file system to
.Ar gid .
The default group is the group of the directory
on which the file system is being mounted.
t Fl m Ar mask Specify the maximum file permissions for files
in the file system.
(For example, a mask of
.Li 755
specifies that, by default, the owner should have
read, write, and execute permissions for files, but
others should only have read and execute permissions.
See
.Xr chmod 1
for more information about octal file modes.)
Only the nine low-order bits of
.Ar mask
are used.
The default mask is taken from the
directory on which the file system is being mounted.
t Fl s Force behaviour to
ignore and not generate Win'95 long filenames.
t Fl l Force listing and generation of
Win'95 long filenames
and separate creation/modification/access dates.

p
If neither
.Fl s
nor
.Fl l
are given,
.Nm
searches the root directory of the filesystem to
be mounted for any existing Win'95 long filenames.
If no such entries are found,
.Fl s
is the default. Otherwise
.Fl l
is assumed.
t Fl 9 Ignore the special Win'95 directory entries even
if deleting or renaming a file. This forces
.Fl s .
t Fl G This option causes the filesystem to be interpreted as an Atari-Gemdos
filesystem. The differences to the msdos filesystem are minimal and
limited to the boot block. This option enforces
.Fl s .

.Sh CAVEATS
The use of the
.Fl 9
flag could result in damaged filesystems,
albeit the damage is in part taken care of by
procedures similar to the ones used in Win'95.

p
The default handling for
.Fl s
and
.Fl l
will result in empty filesystems to be populated
with short filenames only. To generate long filenames
on empty DOS filesystems use
.Fl l .
.Sh HISTORY
The
.Nm
utility first appeared in
.Nx 0.9.
Its predecessor, the
.Nm mount_pcfs
utility appeared in
.Nx 0.8 ,
and was abandoned in favor
of the more aptly-named
.Nm Ns .
