[comp.sys.apollo] Converting unstructered Apollo files to Bitmap Apollo Bitmap files

gsl@caen.engin.umich.edu (Gregg S. Leichtman) (06/29/89)

I have transferred Apollo Bitmap files from one Apollo network to another
at the University of MI, Ann Arbor using FTP.  After the transfer the
new files were of object type Unstruc.  How can I convert them back to
object type Bitmap or transfer them so that they do not change to unstruc?
I transfered them using both ASCII and Binary file types to no avail.
Any help is greatly appreciated!

FTP does not have any concept of file types. That is why
you get an "unstruc" file at the far end. What you want
to do is to convert your Apollo-specific file types into
"unstruc" or "uasc" files before transferring them. There
are 2 easy ways to do this under SR10. The first is to
use the "tar -cvAf file_to_ftp <list of files>" command
under BSD4.3. This will backup your files into a standard
Unix "tar" format file while preserving the Apollo specific
information. You can then FTP this file to another Apollo
and unpack it with a similar "tar" command. The second
method is to use the "wbak -to" command to backup your
Apollo specific files to a "uasc" or "unstruc" file rather
than to a magtape device. There is an SR9.7 version of
wbak which has this capability. I believe it is available
from one of the patch tapes (or you can probably copy it
from the SR9.7 compatibility directory on an SR10 machine).
Both of these methods are nice in that you not only
preserve your file-types, but you can also transfer any
directory structure in a single operation.
