git format-patch for specific commit-ids

for revision ranges, appending ^! (which appropriate escaping) to a commit-id causes it to represent that range beginning/ending with that commit-id inclusively instead of exclusively. So for specifying a revision range consisting of exactly one specific revision (let's call it r1), you can specify r1^! r1

And if you want to generate a patch from all your commits while ignoring all other commits:

for c in `git log --author=Clark | grep ^commit | awk '{print $2}'`; do

git format-patch "$c^\!" "$c";

done
