I was trying to edit an old commit message as explained here.
The thing is that now, when I try to run rebase -i HEAD~5
it says interactive rebase already started
.
So then I try: git rebase --continue
but got this error:
error: Ref refs/heads/master is at 7c1645b447a8ea86ee143dd08400710c419b945b but expected c7577b53d05c91026b9906b6d29c1cf44117d6ba
fatal: Cannot lock the ref 'refs/heads/master'.
Any ideas?

Just wanted to provide a different option for this. In my case, I usually work on my individual branches then merge to master, and the individual commits I do to my local are not that important.
Due to a git hook that checks for the appropriate ticket number on Jira but was case sensitive, I was prevented from pushing my code. Also, the commit was done long ago and I didn't want to count how many commits to go back on the rebase.
So what I did was to create a new branch from latest master and squash all commits from problem branch into a single commit on new branch. It was easier for me and I think it's good idea to have it here as future reference.
From latest master:
git checkout -b new-branch
Then
git merge --squash problem-branch
git commit -m "new message"
FWIW, git rebase interactive now has a "reword" option, which makes this much less painful!
As Gregg Lind suggested, you can use reword to be prompted to only change the commit message (and leave the commit intact otherwise):
git rebase -i HEAD~n
Here, n
is the list of last n commits.
For example, if you use git rebase -i HEAD~4
, you may see something like this:
pick e459d80 Do xyz
pick 0459045 Do something
pick 90fdeab Do something else
pick facecaf Do abc
Now replace pick with reword for the commits you want to edit the messages of:
pick e459d80 Do xyz
reword 0459045 Do something
reword 90fdeab Do something else
pick facecaf Do abc
Exit the editor after saving the file, and next you will be prompted to edit the messages for the commits you had marked reword, in one file per message. Note that it would've been much simpler to just edit the commit messages when you replaced pick
with reword
, but doing that has no effect.

If you don't want to deal with interactive mode then do this:
Update your last pushed commit
git commit --amend -m "New commit message."
Push your new commit message (this will replace the old last commit message to this new one)
git push origin --force **branch-name**

Here's a very nice Gist that covers all the possible cases: https://gist.github.com/nepsilon/156387acf9e1e72d48fa35c4fabef0b4
Overview:
git rebase -i HEAD~X
# X is the number of commits to go back
# Move to the line of your commit, change pick into edit,
# then change your commit message:
git commit --amend
# Finish the rebase with:
git rebase --continue
