Hello, all: What's the best approach to non-interactively rewrite specific commit messages? In this particular case, I am trying to automatically retrieve code review trailers sent to the mailing list and put them into corresponding commits. For example, I have a set of commits: abcabc: This commit does foo bcdbcd: This commit does bar cdecde: This commit does baz They were all sent to the mailing list and a maintainer sent a "Reviewed-by" to the second commit. In a usual interactive rebase session this would be: pick abcabc reword bcdbcd pick cdecde When the edit screen comes up for the bcdbcd commit, the author would manually stick the new trailer into the commit message. However, I can automate all that away with b4 -- just need a sane strategy for non-interactively rewriting entire commit messages at arbitrary points in the recent history. Any pointers? -Konstantin
