cat is probably designed for text files, but it may work on binary files too.
So, it depends on how the export is done (ascii dump? binary one?).

Anyhow, "dd" can help you re-assemble binary files.

cat is designed to join files. It has some text-only options, but it works all right on all kinds of regular files. dd cannot join without manually setting all offsets.

For the record: if 'split' was used, 'cat' will rejoin. (Assuming GNU versions)

if hd space is critical, you can also try:

Code:

for a in <filelist>; do
    cat $a >> join
    rm $a
done
