It was the second time I've typed "git rebase --co", hit tab (for completion) and enter, and the result was --committer-date-is-author-date instead of --continue . Please do ask user before run actions like these! I have not found a way to undo that. I had to perform a reset in the repository. PS: Notice I was expecting a command of interactive rebase, and I got a bunch of commits's date (and hash) changed. Cheers! pasquali
