Extract all attachments from unix mailbox file

Hi guys,

I wondering if someone already wrote a script for this, it looks easy for the first shot but I would say it's a bit advanced.

I want to extract all my email attachments from /var/mail/username (Unix mail format) + from my local mails (Maildir format) to a directory with the original filename, and rename it automatically if 2 attachments have the same name. Thunderbird has an extension for it but I would like to do it with shellscript.

If noone knows script for this (tried googling of course) then I write my own.
Pbly sed would be sufficient to process the whole mailbox file and find the attachments as records.

Doing ops on e-mail is IMHO better (safer) using tools that understand e-mail (just like you don't write your MBR with a hex editor). In this case you could use "munpack":
find dir containing files | while read file; do
 create tempdir and copy file there
 run munpack on file and copy attachments elsewhere
 destroy tempdir (contents)

Thanks for the answers. Actually both of you give an answer which is part of the solution. I was thinking that someone must wrote a tool like munpack for it.

The only problem with munpack that it can't process a single mailbox file, eg: thunderbird's inbox. It only works if I make a test.txt which containst only a single mail which starts with:

From <sender> Mon Jun 16 20:42:11 2008
and ends with

So I still have to cut this file apart to single mails in order to extract the attachments from them but I can do it from here. Thx guys.

Yeah, I read over that in your OP. You could automate separating e-mails and processing them individually with munpack using a procmail recipe.
