Shell scripting an actual parser might be a bit of a pain. My choice
of language for this kind of thing is Python. Parsing an mbox is as
easy as:
import mailbox
mb = mailbox.UnixMailbox(open('/path/to/mbox','r'))
for msg in mb:
document = msg.as_string()
# do whatever you want with document
Equally, Perl, Lua, Ruby etc would make this easy.
