Well, after your earlier suggestion I considered to go with this: - perl -pi -e 's|^Message-Id:\s*<?([^>]+)>?$|Link: https://lore.kernel.org/r/$1|g;' "$1" + perl -pi -e 's|^Message-ID:\s*<?([^>]+)>?$|Link: https://lore.kernel.org/r/$1|i;' "$1" But... > Of course ;-) You need it to run checkpatch on patch series obtained > through "b4 am", before you apply them to your tree: > > $ cat *mbx | formail -s scripts/checkpatch.pl ...this made me wonder if formail would be the better solution. I came up with this: formail -A "Link: https://lore.kernel.org/r/`formail -c -x Message-ID < "${1}" | sed 's!.*<\(.*\)>!\1!'`" < "${1}" | sponge "${1}" Downsides: instead of perl it requires sed and sponge (part of moreutils, which I guess not everyone has installed; but I tried to avoid a big here document or moving files around). Is that worth it? Or is there a way to realize this in a more elegant fashion with tools everyone has installed? Ciao, Thorsten
