git rebase -i

`git rebase -i` stands for interactive rebase. It is a powerful Git command that allows you to modify the commit history of a branch by combining, editing, or removing individual commits.

When you run `git rebase -i`, Git will open a text editor with a list of commits that are part of the branch you want to rebase. Each commit is represented by a hash code and a commit message. You can modify this list to specify which commits you want to keep, which ones you want to modify, and which ones you want to delete.

For example, you can use `git rebase -i` to:

- Combine multiple commits into a single one
- Split a commit into multiple ones
- Change the order of the commits
- Edit the commit messages
- Delete commits that are no longer needed

Once you have made the necessary changes, save the file and exit the editor. Git will then apply your changes to the branch and update the commit history accordingly.

It's important to note that `git rebase -i` rewrites the commit history of a branch, so it should be used with caution. It's also recommended to create a backup branch before using this command, in case anything goes wrong.
