MOUNT_MSDOSFS(8) FreeBSD System Manager's Manual MOUNT_MSDOSFS(8)
NAME
mount_msdosfs - mount an MS-DOS file system
SYNOPSIS
mount_msdosfs [-9ls] [-D DOS_codepage] [-g gid] [-L locale] [-M mask]
[-m mask] [-o options] [-u uid] [-W table] special node
DESCRIPTION
The mount_msdosfs utility attaches the MS-DOS file system residing on the
device special to the global file system namespace at the location
indicated by node. This command is normally executed by 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).
The options are as follows:
-o options
Use the specified mount options, as described in mount(8). The
following MSDOS file system-specific options are available:
longnames
Force Windows 95 long filenames to be visible.
shortnames
Force only the old MS-DOS 8.3 style filenames to be
visible.
nowin95
Completely ignore Windows 95 extended file information.
-u uid Set the owner of the files in the file system to uid. The
default owner is the owner of the directory on which the file
system is being mounted.
-g gid Set the group of the files in the file system to gid. The
default group is the group of the directory on which the file
system is being mounted.
-m mask
Specify the maximum file permissions for files in the file
system. (For example, a mask of 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 chmod(1) for more information about octal file modes. Only
the nine low-order bits of mask are used. The value of -M is
used if it is supplied and -m is omitted. The default mask is
taken from the directory on which the file system is being
mounted.
-M mask
Specify the maximum file permissions for directories in the file
system. The value of -m is used if it is supplied and -M is
omitted. See the previous option's description for details.
-s Force behaviour to ignore and not generate Win'95 long filenames.
-L locale
Specify locale name used for file name conversions for DOS and
Win'95 names. By default ISO 8859-1 assumed as local character
set.
-D DOS_codepage
Specify the MS-DOS code page (aka IBM/OEM code page) name used
for file name conversions for DOS names.
-W table
This option is preserved for backward compatibility purpose only,
and will be removed in the future. Please avoid using this
option.
Specify text file name with conversion table: iso22dos, iso72dos,
koi2dos, koi8u2dos.
EXAMPLES
To mount a Russian MS-DOS file system located in /dev/ada1s1:
mount_msdosfs -L ru_RU.KOI8-R -D CP866 /dev/ada1s1 /mnt
To mount a Japanese MS-DOS file system located in /dev/ada1s1:
mount_msdosfs -L ja_JP.eucJP -D CP932 /dev/ada1s1 /mnt

HISTORY
The predecessor to mount_msdos utility named mount_pcfs appeared in
NetBSD 0.8. It was rewritten in NetBSD 1.0 and first appeared in
FreeBSD 2.0. mount_msdos was renamed to the more aptly-named
mount_msdosfs in FreeBSD 5.0. The character code conversion routine was
added in 2003.
AUTHORS
Initial implementation as mount_pcfs was written by Paul Popelka
<paulp@uts.amdahl.com>. It was rewritten by Christopher G. Demetriou
<cgd@NetBSD.org>. The character code conversion routine was added by
Ryuichiro Imura <imura@ryu16.org>.
CAVEATS
The use of the -9 flag could result in damaged file systems, albeit the
damage is in part taken care of by procedures similar to the ones used in
Win'95.
