|
|
.Sh NAME
|
|
.Nm mount_msdos
|
|
.Nd mount an MS-DOS file system
|
|
.Sh SYNOPSIS
|
|
.Nm mount_msdos
|
|
.Op Fl u Ar uid
|
|
.Op Fl g Ar gid
|
|
.Op Fl m Ar mask
|
|
.Pa special
|
|
.Pa node
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm mount_msdos
|
|
command attaches the MS-DOS filesystem residing on
|
|
the device
|
|
.Pa special
|
|
to the global filesystem namespace at the location
|
|
indicated by
|
|
.Pa node .
|
|
This command is normally executed by
|
|
.Xr 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).
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Fl u
|
|
Set the owner of the files in the file system to
|
|
.Ar uid .
|
|
The default owner is the owner of the directory
|
|
on which the file system is being mounted.
|
|
.It Fl g
|
|
Set the group of the files in the file system to
|
|
.Ar gid .
|
|
The default group is the group of the directory
|
|
on which the file system is being mounted.
|
|
.It Fl m
|
|
Specify the maximum file permissions for files
|
|
in the file system.
|
|
(For example, a mask of
|
|
.Li 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
|
|
.Xr chmod 1
|
|
for more information about octal file modes.)
|
|
Only the nine low-order bits of
|
|
.Ar mask
|
|
are used.
|
|
The default mask is taken from the
|
|
directory on which the file system is being mounted.

.Sh CAVEATS
|
|
The
|
|
.Nm msdos
|
|
filesystem is not known to work reliably with filesystems created by versions
|
|
of MS-DOS later than version 3.3.
|
|
.Pp
|
|
The limitations on file names imposed by MS-DOS are strange, at best.
|
|
For instance, they are
|
|
limited to single-case, 8 character names with 3 character extensions.
|
|
.Sh HISTORY
|
|
The
|
|
.Nm mount_msdos
|
|
utility first appeared in FreeBSD 2.0.
|
|
Its predecessor, the
|
|
.Nm mount_pcfs
|
|
utility appeared in FreeBSD 1, and was abandoned in favor
|
|
of the more aptly-named
|
|
.Nm mount_msdos .
