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:"banlktikof4txunllufrznsd6k2zys7s...@mail.gmail.com" - [O] Worg update - id:"m1wrfiz3ch....@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... > /tmp/thread-I-m-interested-in.mbox is a mbox with messages > I'minterested in, the "real" ones. really.mid is a list of > Message-IDs of these "real" emails. rest.mbox is a mbox with the > other emails, Emacs showed in his notmuch show buffer but are > other threads. > > Since there is no match I concluded, the threads are not linked. > Perhaps I made a mistake.
