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

NAME
     mount_msdosfs -- mount an MS-DOS file system

SYNOPSIS
     mount_msdosfs [-o options]	[-u uid] [-g gid] [-m mask] [-s] [-l] [-9]
		   [-L locale] [-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	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).

     The options are as	follows:

     -o	options
	     Use the specified mount options, as described in mount(8),	or one
	     of	the MSDOS file system-specific options shortnames, longnames
	     or	nowin95, all of	which can be used to affect Windows name
	     translation in the	underlying file	system.

     -u	uid  Set the owner of the files	in the file system to uid.  The	de-
	     fault owner is the	owner of the directory on which	the file sys-
	     tem is being mounted.

     -g	gid  Set the group of the files	in the file system to gid.  The	de-
	     fault group is the	group of the directory on which	the file sys-
	     tem 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	     Force behaviour to	ignore and not generate	Win'95 long filenames.

     -l	     Force listing and generation of Win'95 long filenames and sepa-
	     rate 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 as-
	     sumed.

     -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 internal uppercase and lowercase
	     conversions for DOS and Win'95 names.  By default ISO 8859-1 as-
	     sumed as local character set.

     -W	table
	     Specify text file with 3 conversion tables:

	     1.	  Local	character set to Unicode conversion table (upper half)
		  for Win'95 long names, 128 Unicode codes separated by	8 per
		  row.	If some	code not present in Unicode, use 0x003F	code
		  ('?')	as replacement.

	     2.	  DOS to local character set conversion	table (upper half) for
		  DOS names, 128 character codes separated by 8	per row.  Code
		  0x3F ('?') used for impossible translations.

	     3.	  Local	character set to DOS conversion	table (upper half) for
		  DOS names, 128 character codes separated by 8	per row.  Some
		  codes	have special meaning:

		  0x00	  character disallowed in DOS file name;

		  0x01	  character should be replaced by '_' in DOS file
			  name;

		  0x02	  character should be skipped in DOS file name;

	     By	default	ISO 8859-1 assumed as local character set.  If file
	     path isn't	absolute, /usr/libdata/msdosfs/	prefix prepended.

FILES

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.

     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 file systems
     larger than 1G are	shrunk to smaller than 1G using	FIPS.

HISTORY
     The mount_msdosfs utility first appeared in FreeBSD 2.0.  Its predeces-
     sor, the mount_pcfs utility appeared in FreeBSD 1.0, and was abandoned in
     favor of the more aptly-named mount_msdosfs.
