I believe I used the cat command to append a file beside another file (instead of below it) but I did not document it any where and I can't remember exactly how I did it. Has anyone else done this? I have tried all the cat options individually with no luck. It may be a combination of options.

mcat(1) General Commands Manual mcat(1)
Name
mcat - dump raw disk image
Note of warning
This manpage has been automatically generated from mtools's texinfo documentation, and may not be entirely accurate or complete. See the
end of this man page for details.
Description
The mcat command is used to copy an entire disk image from or to the floppy device. It uses the following syntax:
mcat [-w] drive:
Mcat performs the same task as the Unix cat command. It is included into the mtools package, since cat cannot access remote floppy devices
offered by the mtools floppy daemon. Now it is possible to create boot floppies remotely.
The default operation is reading. The output is written to stdout.
If the -w option is specified, mcat reads a disk-image from stdin and writes it to the given device. Use this carefully! Because of the
low-level nature of this command, it will happily destroy any data written before on the disk without warning!

Viewing the texi doc
This manpage has been automatically generated from mtools's texinfo documentation. However, this process is only approximative, and some
items, such as crossreferences, footnotes and indices are lost in this translation process. Indeed, these items have no appropriate repre-
sentation in the manpage format. Moreover, not all information has been translated into the manpage version. Thus I strongly advise you
to use the original texinfo doc. See the end of this manpage for instructions how to view the texinfo doc.
* To generate a printable copy from the texinfo doc, run the following commands:
./configure; make dvi; dvips mtools.dvi
* To generate a html copy, run:
./configure; make html
A premade html can be found at `http://www.gnu.org/software/mtools/manual/mtools.html'
* To generate an info copy (browsable using emacs' info mode), run:
./configure; make info
The texinfo doc looks most pretty when printed or as html. Indeed, in the info version certain examples are difficult to read due to the
quoting conventions used in info.
