<P>mkmanifest—Create a shell script to restore UNIX filenames
</P>
<P><B>SYNOPSIS</B></P>
<!-- CODE SNIP //-->
<PRE>mkmanifest [ FILES ]
</PRE>
<!-- END CODE SNIP //-->
<P><B>DESCRIPTION</B></P>
<P>mkmanifest creates a shell script that will aid in the restoration of UNIX filenames that got clobbered by the
MS-DOS filename restrictions. MS-DOS filenames are restricted to eight-character names, three-character extensions, uppercase
only, no device names, and no illegal characters.
</P>
<P>The mkmanifest program is compatible with the methods used in
pcomm, arc, and mtools to change perfectly good
UNIX filenames to fit the MS-DOS restrictions.
</P>
<P><B>Example</B></P>
<P>Say you want to copy the following UNIX FILES to an MS-DOS disk (using the
mcopy command):
</P>
<!-- CODE SNIP //-->
<PRE>very_long_name
2.many.dots
illegal:
good.c
prn.dev
Capital
</PRE>
<!-- END CODE SNIP //-->
<P>mcopy will convert the names to
</P>
<!-- CODE SNIP //-->
<PRE>very_lon
2xmany.dot
illegalx
good.c
xprn.dev
capital
</PRE>
<!-- END CODE SNIP //-->
<P>The command:
</P>
<!-- CODE SNIP //-->
<PRE>mkmanifest very_long_name 2.many.dots illegal: good.c prn.dev Capital > manifest
</PRE>
<!-- END CODE SNIP //-->
<P>would produce the following:
</P>
<!-- CODE SNIP //-->
<PRE>mv very_lon very_long_name
mv 2xmany.dot 2.many.dots
mv illegalx illegal:
mv xprn.dev prn.dev
mv capital Capital
</PRE>
<!-- END CODE SNIP //-->
<A NAME="PAGENUM-325"><P>Page 325</P></A>
<P>Notice that good.c did not require any conversion, so it did not appear in the output.
</P>
<P>Suppose I've copied these FILES from the disk to another UNIX system, and I now want the FILES back to their original
names. If the file manifest (the output captured above) was sent along with those FILES, it could be used to convert the filenames.
</P>
<P><B>BUGS</B></P>
<P>The short names generated by mkmanifest follow the old convention (from
mtools-2.0.7) and not the one from Windows 95 and
mtools-3.0.

</P>
<!-- CODE SNIP //-->
<PRE>[_m mode] [--mode=mode] [--help] [--version]
</PRE>
<!-- END CODE SNIP //-->
<P><B>DESCRIPTION</B></P>
<P>This manual page documents the GNU version of
mknod. mknod creates a FIFO, character special file, or block special file
with the given filename. By default, the mode of created FILES is 0666 minus the bits set in the umask.
</P>
<P>The argument after filename specifies the type of file to make:
</P>
<P>p for a FIFO
</P>
<P>b for a block (buffered) special file
</P>
<P>c or u for a character (unbuffered) special file
</P>
<P>When making a block or character special file, the major and minor device numbers must be given after the file type.
