Did you mean to do case-insensitive grep? ('-i' instead of '-I').

Also, the '-F' option expects input on stdin, not a filename.


Try this (with all individual threads split into separate mboxes):

  #+begin_src sh
    for i in $(ls *.mbox) ; do
        grep -i '^Message-Id:' "${i}" | \
            sed -e 's/^.\{13\}//' -e 's/>$//' \
            > "${i}.mids"
    done
    for i in $(ls *.mids) ; do
        echo "## Grepping for ${i}'s Message-Ids"
        grep -i -F "$(cat ${i})" *.mbox
    done
  #+end_src


Here's another couple of threads squashed into a single one:
- [O] [Use Question] Capture and long lines
  - id:"BANLkTikoF4tXuNLLufRzNSD6k2ZYs7sUcg@mail.gmail.com"
- [O] Worg update
  - id:"m1wrfiz3ch.fsf@tsdye.com"
- [O] Table formula to convert hex to dec
  - id:"20110724080054.GB16388@x201"
- [O] ICS import?
  - id:"20120125173421.GQ3747@x201"


AFAICT, none of them share Message-Id's...
