mount_msdosfs 36.Nd mount an MS-DOS file system 37.Sh SYNOPSIS 38.Nm 39.Op Fl 9ls 40.Op Fl D Ar DOS_codepage 41.Op Fl g Ar gid 42.Op Fl L Ar locale 43.Op Fl M Ar mask 44.Op Fl m Ar mask 45.Op Fl o Ar options 46.Op Fl u Ar uid 47.Op Fl W Ar table 48.Ar special node 49.Sh DESCRIPTION 50The 51.Nm 52utility attaches the MS-DOS file system residing on 53the device 54.Pa special 55to the global file system namespace at the location 56indicated by 57.Pa node . 58This command is normally executed by 59.Xr mount 8 60at boot time, but can be used by any user to mount an 61MS-DOS file system on any directory that they own (provided, 62of course, that they have appropriate access to the device that 63contains the file system). 64.Pp 65The options are as follows: 66.Bl -tag -width Ds 67.It Fl o Ar options 68Use the specified mount 69.Ar options , 70as described in 71.Xr mount 8 . 72The following MSDOS file system-specific options are available: 73.Bl -tag -width indent 74.It Cm longnames 75Force Windows 95 long filenames to be visible. 76.It Cm shortnames 77Force only the old MS-DOS 8.3 style filenames to be visible. 78.It Cm nowin95 79Completely ignore Windows 95 extended file information. 80.El 81.It Fl u Ar uid 82Set the owner of the files in the file system to 83.Ar uid . 84The default owner is the owner of the directory 85on which the file system is being mounted. 86.It Fl g Ar gid 87Set the group of the files in the file system to 88.Ar gid . 89The default group is the group of the directory 90on which the file system is being mounted. 91.It Fl m Ar mask 92Specify the maximum file permissions for files 93in the file system. 94(For example, a 95.Ar mask 96of 97.Li 755 98specifies that, by default, the owner should have 99read, write, and execute permissions for files, but 100others should only have read and execute permissions. 101See 102.Xr chmod 1 103for more information about octal file modes. 104Only the nine low-order bits of 105.Ar mask 106are used. 107The value of 108.Ar -M 109is used if it is supplied and 110.Ar -m 111is omitted. 112The default 113.Ar mask 114is taken from the 115directory on which the file system is being mounted. 116.It Fl M Ar mask 117Specify the maximum file permissions for directories 118in the file system. 119The value of 120.Ar -m 121is used if it is supplied and 122.Ar -M 123is omitted. 124See the previous option's description for details. 125.It Fl s 126Force behaviour to 127ignore and not generate Win'95 long filenames. 128.It Fl l 129Force listing and generation of 130Win'95 long filenames 131and separate creation/modification/access dates. 132.Pp 133If neither 134.Fl s 135nor 136.Fl l 137are given, 138.Fl l 139is the default. 140.It Fl 9 141Ignore the special Win'95 directory entries even 142if deleting or renaming a file. 143This forces 144.Fl s . 145.\".It Fl G 146.\"This option causes the file system to be interpreted as an Atari-Gemdos 147.\"file system. 148.\"The differences to the MS-DOS file system are minimal and 149.\"limited to the boot block. 150.\"This option enforces 151.\".Fl s . 152.It Fl L Ar locale 153Specify locale name used for file name conversions 154for DOS and Win'95 names. 155By default ISO 8859-1 assumed as local character set. 156.It Fl D Ar DOS_codepage 157Specify the MS-DOS code page (aka IBM/OEM code page) name used for 158file name conversions for DOS names. 159.It Fl W Ar table 160.Bf Em 161This option is preserved for backward compatibility purpose only, 162and will be removed in the future. 163Please avoid using this option. 164.Ef 165.Pp 166Specify text file name with conversion table: 167.Pa iso22dos , iso72dos , koi2dos , koi8u2dos . 168.El 169.Sh EXAMPLES 170To mount a Russian MS-DOS file system located in 171.Pa /dev/ada1s1 :

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