The author shares their experience with using the `git rebase -i` command to change commit history, which they found to be an interactive and powerful tool for managing code changes. They explain that this command allows developers to alter individual commits as part of the basic rebase process, making it possible to squash, fixup, reword, or edit commits in various ways. The author provides examples of how to use these options to address common scenarios such as changing an old commit message, squashing multiple commits together, and fixing code conflicts that may arise during the rebase process. They emphasize the importance of understanding each option carefully before applying them to avoid losing work or introducing errors into the repository.
