CompTIA Linux+ XK0-006 (V8) Practice Question

Using git rebase -i HEAD~6 tells Git to start an interactive rebase that rewinds the branch to the parent of the sixth-latest commit and then replays those six commits. The interactive todo list allows you to mark five of the commits as squash or fixup so they are folded into the first, producing one consolidated commit and a linear history.

git merge --squash HEAD~6 only stages a squashed snapshot and still requires a separate git commit; it does not provide an interactive interface and leaves a different history shape. git reset --soft HEAD~6 moves the branch pointer backward but loses the original commit objects until a new commit is made, so it is not a squash workflow. git rebase --onto origin/main rebases the branch onto the tip of origin/main; unless the -i option plus the correct upstream range is added, it neither squashes the six commits nor opens the interactive editor.
