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:
large
- Support file systems larger than 128 gigabytes at the expense of 32 bytes of kernel memory for each file on disk. This memory will not be reclaimed until the file system has been unmounted.
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
- Force listing and generation of Win'95 long filenames and separate
creation/modification/access dates.
If neither
-s
nor-l
are given,mount_msdosfs
searches the root directory of the file system to be mounted for any existing Win'95 long filenames. If no such entries are found, but short DOS filenames are found,-s
is the default. Otherwise-l
is assumed. -9
- Ignore the special Win'95 directory entries even if deleting or renaming a
file. This forces
-s
. -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 mount_msdosfs
utility first appeared
in FreeBSD 2.0. Its predecessor, the
mount_pcfs
utility appeared in
FreeBSD 1.0, and was abandoned in favor of the more
aptly-named mount_msdosfs
.
The character code conversion routine was added by
Ryuichiro Imura ⟨imura@ryu16.org⟩ at
2003.
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.
