38 .Nd mount an MS-DOS file system
56 utility attaches the MS-DOS file system residing on
59 to the global file system namespace at the location
62 This command is normally executed by
64 at boot time, but can be used by any user to mount an
65 MS-DOS file system on any directory that they own (provided,
66 of course, that they have appropriate access to the device that
67 contains the file system).
69 The options are as follows:
72 Use the specified mount
76 or one of the MSDOS file system-specific options
81 all of which can be used to affect Windows name translation in the
82 underlying file system.
84 Set the owner of the files in the file system to
86 The default owner is the owner of the directory
87 on which the file system is being mounted.
89 Set the group of the files in the file system to
91 The default group is the group of the directory
92 on which the file system is being mounted.
94 Specify the maximum file permissions for files
100 specifies that, by default, the owner should have
101 read, write, and execute permissions for files, but
102 others should only have read and execute permissions.
105 for more information about octal file modes.)
106 Only the nine low-order bits of
112 directory on which the file system is being mounted.
115 ignore and not generate Win'95 long filenames.
117 Force listing and generation of
118 Win'95 long filenames
119 and separate creation/modification/access dates.
127 searches the root directory of the file system to
128 be mounted for any existing Win'95 long filenames.
129 If no such entries are found, but short DOS filenames are found,
136 Ignore the special Win'95 directory entries even
137 if deleting or renaming a file.
141 .\"This option causes the file system to be interpreted as an Atari-Gemdos
142 .\"file system. The differences to the MS-DOS file system are minimal and
143 .\"limited to the boot block. This option enforces
146 Specify locale name used for internal uppercase and lowercase conversions
147 for DOS and Win'95 names.
148 By default ISO 8859-1 assumed as local character set.
150 Specify text file with 3 conversion tables:
153 Local character set to Unicode conversion table (upper half) for Win'95 long
154 names, 128 Unicode codes separated by 8 per row.
155 If some code not present in Unicode, use
156 0x003F code ('?') as replacement.
158 DOS to local character set conversion table (upper half) for DOS names,
159 128 character codes separated by 8 per row.
160 Code 0x3F ('?') used for impossible translations.
162 Local character set to DOS conversion table (upper half) for DOS names,
163 128 character codes separated by 8 per row.
164 Some codes have special meaning:
167 character disallowed in DOS file name;
169 character should be replaced by '_' in DOS file name;
171 character should be skipped in DOS file name;
175 By default ISO 8859-1 assumed as local character set.
176 If file path isn't absolute,
177 .Pa /usr/libdata/msdosfs/
181 .Bl -tag -width /usr/libdata/msdosfs -compact
182 .It Pa /usr/libdata/msdosfs
183 default place for character sets conversion tables
193 flag could result in damaged file systems,
194 albeit the damage is in part taken care of by
195 procedures similar to the ones used in Win'95.
198 and earlier versions could not handle cluster sizes larger than 16K.
199 Just mounting an MS-DOS file system could cause corruption to any
201 Cluster sizes larger than 16K are unavoidable for file system sizes
202 larger than 1G, and also occur when file systems larger than 1G are
203 shrunk to smaller than 1G using FIPS.
