MOUNT_MSDOS(8)              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 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.

CAVEATS
     FreeBSD 2.1 and earlier versions could not handle cluster sizes larger
     than 16K.  Just mounting an MS-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.
