MOUNT_MSDOS(8) BSD System Manager's Manual MOUNT_MSDOS(8)NAMEmount_msdos - mount an MS-DOS file system
SYNOPSISmount_msdos [-o options] [-u uid] [-g gid] [-m mask] [-s] [-l] [-9] [-G]
special node
DESCRIPTION
The mount_msdos command attaches the MS-DOS filesystem residing on the
device special to the global filesystem namespace at the location indi-
cated 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).
Options can be specified as a single letter flag, with an optional value,
in the standard getopt(3) style. Alternatively, options can be given as
arguments via the -o flag. In this form, a long name can be used; if a
value is required, it should appear following an equals sign, e.g., -o
uid=101. The long forms below appear in brackets.
The options are as follows:
-o options
Use the specified mount options, as described in mount(8).
-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 sys-
tem. (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 default mask is taken
from the directory on which the file system is being mounted.
-s [short]
Force behaviour to ignore and not generate Win'95 long filenames.
-l [long]
Force listing and generation of Win'95 long filenames and sepa-
rate creation/modification/access dates.
If neither -s [short] nor -l [long] are given, mount_msdos
searches the root directory of the filesystem to be mounted for
any existing Win'95 long filenames. If no such entries are
found, -s [short] is the default. Otherwise -l [long] is assumed.
-9 [nowin95]
Ignore the special Win'95 directory entries even if deleting or
renaming a file. This forces -s [short].
-G [gem]
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 -s
[short].
SEE ALSOmount(2), unmount(2), fstab(5), mount(8)CAVEATS
The use of the -9 [nowin95] flag could result in damaged filesystems, al-
beit the damage is in part taken care of by procedures similar to the
ones used in Win'95.
The default handling for -s [short] and -l [long] will result in empty
filesystems to be populated with short filenames only. To generate long
filenames on empty DOS filesystems use -l [long].
Note that Win'95 handles only access dates, but not access times.
HISTORY
The mount_msdos utility first appeared in NetBSD 0.9. Its predecessor,
the mount_pcfs utility appeared in NetBSD 0.8, and was abandoned in favor
of the more aptly-named mount_msdos.
