Mutt is a really nice tool, but for this I would probably reach first
for 'reformime' from the maildrop package.  (I'm a long-time maildrop
fan.)

I have used ripmime without problems but on individual messages from a
Maildir, not on a large mbox.

You should first define the macro! You could do it interactively (for
testing purposes) by typing : (colon) followed by the macro definition
above, i.e.,
  :macro index Ys...
by making a text file whose content is the macro definition and
sourcing it from mutt
  :source filename.txt
or by adding it to you ~/.mutt/muttrc file so that it is loaded
automatically on the next mutt startup. Afterwards, you should be
able to call the macro when you are in the 'index' view. You could
replace Ys to the key sequence of your choice to call the macro.

Hi, I try to use your script, nut, when I hint Y, mutt tell me that "Key Y is
not mapped"

What could I doing wrong?

tried ripmime and munpak about a year ago to save all attachments from 
a large MBOX and it was everything but a hasslefree experience. Various 
attachments were missed or not processed, some segfaults.
Those tools are apparently not as robust as mutt is.

Ended up splitting the MBOX by formail 
  cat MBOX | formail -ds sh -c 'cat > msg.$FILENO'
and processing messages by 
  ripmime -v  --name-by-type --verbose-contenttype --verbose-defects  -i "$f"
.. and hoping not much was missed by this apporach.

Thanks - yes, my intention was just to demo the approach. I've done
a few MIME walks in Python so this was a simple modification of some
existing code. Even with many years of mutt experience I think rolling
this up last night was faster than getting something steady and sturdy
going with mutt macros, and I have more confidence in it.

There's certainly room to improve if anyone wants to take this further,
and you've raised a good point above. A few things ought to be sanitized
more.
