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

NAME
     mount_msdos -- mount an MS-DOS file system

SYNOPSIS
     mount_msdos [-o options] [-u uid] [-g gid] [-m mask] 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 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).

     -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 infor-mation information
             mation 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.

CAVEATS
     FreeBSD 2.1 and earlier versions could not handle cluster sizes larger than 16K.  Just mounting an MS-DOS MSDOS
     DOS file system could cause corruption to any mounted file system.  Cluster sizes larger than 16K are
     unavoidable for file system sizes larger than 1G, and also occur when filesystems larger than 1G are
     shrunk to smaller than 1G using FIPS.

HISTORY
     The mount_msdos 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_msdos.
