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 171.Sh EXAMPLES 172To mount a Russian MS-DOS file system located in 173.Pa

http://www.microsoft.com/globaldev/reference/oslocversion.mspx . 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. 223
