MOUNT_MSDOS(8)          NetBSD System Manager's Manual          MOUNT_MSDOS(8)

NAME
     mount_msdos -- mount an MS-DOS file system

SYNOPSIS
     mount_msdos [-9Gls] [-g gid] [-M mask] [-m mask] [-o options] [-t gmtoff]
                 [-u uid] 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.  Both special and node are converted to absolute paths
     before use.  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 direc-
     tory that they own (provided, of course, that they have appropriate
     access to the device that contains the file system).

     Support for FAT16 and VFAT32 as well as long file names is available.

     The options are as follows:

     -9            Ignore the special Win'95 directory entries even if delet-
                   ing or renaming a file.  This forces -s.

     -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 -s.

     -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.

     -l            Force listing and generation of Win'95 long filenames and
                   separate creation/modification/access dates.

                   If neither -s nor -l 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 is the default.  Otherwise -l is assumed.

     -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.

     -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.

     -o options    Use the specified mount options, as described in mount(8).

     -s            Force behaviour to ignore and not generate Win'95 long
                   filenames.  See also -l.

     -t gmtoff     Set the time zone offset (in seconds) from UTC to gmtoff,
                   with positive values indicating east of the Prime Meridian.
                   If not set, the user's current time zone will be used.

     -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.

EXAMPLES
     To remove the 'execute' permission bit for all files, but still keep
     directories searchable, use:

           mount_msdos -m 0644 -M 0755 /dev/wd0e /msdos

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.

BUGS
     Compressed partitions are not supported.

     The use of the -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.

     The default handling for -s and -l will result in empty filesystems to be
     populated with short filenames only.  To generate long filenames on empty
     DOS filesystems use -l.
