(or subdirectory) will be renamed in the same directory, instead of being moved to the current
mcd directory as would be the case with mmove. Unlike the MS-DOS version of
REN, mren can be used to rename directories.

<A NAME="PAGENUM-331"><P>Page 331</P></A>
<P><B>DESCRIPTION</B></P>
<P>mtools is a public domain collection of programs to allow UNIX systems to read, write, and manipulate FILES on an
MS-DOS FILESystem (typically a floppy disk). Where reasonable, each program attempts to emulate the MS-DOS equivalent
command. However, unnecessary restrictions and oddities of DOS are not emulated. For instance, it is possible to move
subdirectories from one subdirectory to another.
</P>
<P>MS-DOS filenames are optionally composed of a drive letter followed by a colon, a subdirectory, and a filename.
Filenames without a drive letter refer to UNIX FILES. Subdirectory names can use either the
/ or \ separator. The use of the \ separator or wildcards will require the names to be enclosed in quotes to protect them from the shell. (Note: Wildcards in
UNIX filenames should not be enclosed in quotes, because here users want the shell to expand them.)
</P>
<P><B>Differences with MS-DOS</B></P>
<P>The regular expression "pattern matching" routines follow the UNIX-style rules. For example,
* matches all MS-DOS FILES in lieu of *.*. The archive, hidden, read-only, and system attribute bits are ignored during pattern matching.
</P>
<P>All OPTIONS use the - (minus) flag, not / as you'd expect in MS-DOS.
</P>
<P>Most mtools commands allow multiple filename parameters, which doesn't follow MS-DOS conventions, but which is
more user friendly.
</P>
<P><B>Working Directory</B></P>
<P>The mcd command is used to establish the device and the current working directory (relative to the MS-DOS
FILESystem); otherwise, the default is assumed to be
A:/. However, unlike MS-DOS, there is only one working directory, and not one
per drive.
</P>
<P><B>VFAT-Style Long Filenames</B></P>
<P>This version of mtools supports VFAT-style long filenames. If a UNIX filename is too long to fit in a short DOS name, it
is stored as a VFAT long name, and a companion short name is generated. This short name is what you see when you
examine the disk with a pre-7.0 version of DOS. The following table shows some EXAMPLES of short names:
</P>
<TABLE>
<TR><TD>
UNIX Name
</TD><TD>
MS-DOS Name
</TD><TD>
Reason for the Change
</TD></TR><TR><TD>
thisisatest
</TD><TD>
THISISAT
</TD><TD>
Filename too long
</TD></TR><TR><TD>
alain.knaff
</TD><TD>
ALAIN.KNA
</TD><TD>
Extension too long
</TD></TR><TR><TD>
prn.txt
</TD><TD>
XRN.TXT
</TD><TD>
PRN is a device name
</TD></TR><TR><TD>
.abc
</TD><TD>
X.ABC
</TD><TD>
Null filename
</TD></TR><TR><TD>
hot+cold
</TD><TD>
HOTXCOLD
</TD><TD>
Illegal character
</TD></TR></TABLE>
<P>The initial UNIX-style filename (whether long or short) is also called
primary name, and the derived short name is also
called secondary name.
</P>
<P>Example:
</P>
<!-- CODE SNIP //-->
<PRE>mcopy /etc/motd a:Reallylongname
</PRE>
<!-- END CODE SNIP //-->
<P>mtools creates a VFAT entry for Reallylongname, and uses
REALLYLO as a short name. Reallylongname is the primary name,
and REALLYLO is the secondary name.
</P>
<P>In this example:
</P>
<!-- CODE SNIP //-->
<PRE>copy /etc/motd a:motd
</PRE>
<!-- END CODE SNIP //-->
<P>motd fits into the DOS filename limits. mtools doesn't need to derivate another name.
motd is the primary name, and there is no secondary name.
</P>
<P>In a nutshell: The primary name is the long name, if one exists, or the short name if there is no long name.
