36.Sh NAME
37.Nm mount_msdosfs
38.Nd mount an MS-DOS file system
39.Sh SYNOPSIS
40.Nm
41.Op Fl 9ls
42.Op Fl D Ar DOS_codepage
43.Op Fl g Ar gid
44.Op Fl L Ar locale
45.Op Fl M Ar mask
46.Op Fl m Ar mask
47.Op Fl o Ar options
48.Op Fl u Ar uid
49.Op Fl W Ar table
50.Ar special node
51.Sh DESCRIPTION
52The
53.Nm
54utility attaches the MS-DOS file system residing on
55the device
56.Pa special
57to the global file system namespace at the location
58indicated by
59.Pa node .
60This command is normally executed by
61.Xr mount 8
62at boot time, but can be used by any user to mount an
63MS-DOS file system on any directory that they own (provided,
64of course, that they have appropriate access to the device that
65contains the file system).
66.Pp
67The options are as follows:
68.Bl -tag -width Ds
69.It Fl o Ar options
70Use the specified mount
71.Ar options ,
72as described in
73.Xr mount 8 .
74The following MSDOS file system-specific options are available:
75.Bl -tag -width indent
76.It Cm longnames
77Force Windows 95 long filenames to be visible.
78.It Cm shortnames
79Force only the old MS-DOS 8.3 style filenames to be visible.
80.It Cm nowin95
81Completely ignore Windows 95 extended file information.
82.El
83.It Fl u Ar uid
84Set the owner of the files in the file system to
85.Ar uid .
86The default owner is the owner of the directory
87on which the file system is being mounted.
88.It Fl g Ar gid
89Set the group of the files in the file system to
90.Ar gid .
91The default group is the group of the directory
92on which the file system is being mounted.
93.It Fl m Ar mask
94Specify the maximum file permissions for files
95in the file system.
96(For example, a
97.Ar mask
98of
99.Li 755
100specifies that, by default, the owner should have
101read, write, and execute permissions for files, but
102others should only have read and execute permissions.
103See
104.Xr chmod 1
105for more information about octal file modes.
106Only the nine low-order bits of
107.Ar mask
108are used.
109The value of
110.Ar -M
111is used if it is supplied and
112.Ar -m
113is omitted.
114The default
115.Ar mask
116is taken from the
117directory on which the file system is being mounted.
118.It Fl M Ar mask
119Specify the maximum file permissions for directories
120in the file system.
121The value of
122.Ar -m
123is used if it is supplied and
124.Ar -M
125is omitted.
126See the previous option's description for details.
127.It Fl s
128Force behaviour to
129ignore and not generate Win'95 long filenames.
130.It Fl l
131Force listing and generation of
132Win'95 long filenames
133and separate creation/modification/access dates.
134.Pp
135If neither
136.Fl s
137nor
138.Fl l
139are given,
140.Fl l
141is the default.
142.It Fl 9
143Ignore the special Win'95 directory entries even
144if deleting or renaming a file.
145This forces
146.Fl s .
147.\".It Fl G
148.\"This option causes the file system to be interpreted as an Atari-Gemdos
149.\"file system.
150.\"The differences to the MS-DOS file system are minimal and
151.\"limited to the boot block.
152.\"This option enforces
153.\".Fl s .
154.It Fl L Ar locale
155Specify locale name used for file name conversions
156for DOS and Win'95 names.
157By default ISO 8859-1 assumed as local character set.
158.It Fl D Ar DOS_codepage
159Specify the MS-DOS code page (aka IBM/OEM code page) name used for
160file name conversions for DOS names.
161.It Fl W Ar table
162.Bf Em
163This option is preserved for backward compatibility purpose only,
164and will be removed in the future.
165Please avoid using this option.
166.Ef
167.Pp
168Specify text file name with conversion table:
169.Pa iso22dos , iso72dos , koi2dos , koi8u2dos .
170.El

190.Sh HISTORY
191The predecessor to
192.Nm mount_msdos
193utility named
194.Nm mount_pcfs
195appeared in
196.Nx 0.8 .
197It was rewritten in
198.Nx 1.0
199and first appeared in
200.Fx 2.0 .
201.Nm mount_msdos
202was renamed to the more aptly-named
203.Nm
204in
205.Fx 5.0 .
206The character code conversion routine was added in 2003.
207.Sh AUTHORS
208Initial implementation as
209.Nm mount_pcfs
210was written by
211.An -nosplit
212.An Paul Popelka Aq Mt paulp@uts.amdahl.com .
213It was rewritten by
214.An Christopher G. Demetriou Aq Mt cgd@NetBSD.org .
215The character code conversion routine was added by
216.An Ryuichiro Imura Aq Mt imura@ryu16.org .
217.Sh CAVEATS
218The use of the
219.Fl 9
220flag could result in damaged file systems,
221albeit the damage is in part taken care of by
222procedures similar to the ones used in Win'95.
