如何更改尚未推送的倒数第二个提交消息

Question

I usually submit a list of commits for review. If I have the following commits:

 HEAD (not pushed) Commit1 (not pushed) (Merged master here) Commit2 Commit3 ...

I know that I can modify head commit with git commit --amend. But how can I modify Commit1? given that it is not the HEAD commit and not pushed. git rebase does not show it in list of I enter git rebase -i HEAD~3.

Answer 1

Thank you for the answers, Actually the commit message I wanted to modify was merge commit and git rebase command does not show merge commits(if not pushed I guess) in rebase HEAD~n command and it was the main issue.

With the help of my colleague I was able to resolve by this command

git rebase -i -p HEAD~3

where -p is for preserve merges Still not able to understand how this works fully, but it did the job.

Answer 2

If you:

• don't want to do an integrative rebase (git rebase @~2)
• don't want to use a set of commands to do the same non-interactively

You can use git filter-repo and its callbacks , based on the content of the old message:

git-filter-repo --message-callback '
  if b"known content" in message:
    message = "New message\npossibly on\n several lines""
  return message'
