I’ve got an archive created using 2.1.0beta0 archive settings to bzip2 compression and to 650 Mb volumes and I need to extract files from the series, but I’ve had problems figuring out what I need to do to the file now.

Tar with multi-volume setting won’t read the file because it is compressed, but trying to unzip the beginning file using bunzip2 file_name just complains that the compressed file ends unexpectedly.

I've got an archive created using 2.1.0beta0 archive settings to bzip2
compression and to 650 Mb volumes and I need to extract files from the
series, but I've had problems figuring out what I need to do to the file
now.

Tar with multi-volume setting won't read the file because it is
compressed, but trying to unzip the beginning file using bunzip2
file_name just complains that the compressed file ends unexpectedly.

This should work:

1) Copy all the files into a single directory.

2) Cat them together (undo the split)

3) bunzip2 the file (undo the bzip2)

4) tar xvf the uncompressed file.

if that should work, then so should this:
cat file1 file2 ... | bunzip2 | tar xvf -
(and given the probably size of a bzipped tar that needed to be
split, i'd guess it would be preferable)

Probably what you really want here is a program that reads
the CDs directly and sends the output to a pipe, prompting
for each CD as needed. I know I've seen one of those in the
past but I can't remember the name.

i think cpio will do it, all by itself. of course, last time i
tried it was almost exactly 20 years ago now.
