[All 200-901 Questions]

Which command reverses the last commit without changing the index file or the working tree position?

Show Suggested Answer Hide Answer
Suggested Answer: C

The command git reset --soft HEAD^ reverses the last commit but keeps the changes staged in the index file (staging area) and working directory. Here's what the command does:

git reset --soft: Moves the HEAD pointer to the specified commit (in this case, the parent of the current commit, denoted by HEAD^) but leaves the changes from the reset commit in the staging area.

HEAD^: Refers to the parent commit of the current HEAD.

This command is useful when you want to uncommit the last commit but keep the changes for further modification or recommit them.

C) is nice for keeping changes, but A) is safer for just reverting.

I feel like "git reset --soft HEAD^" might be the right answer, but I can't recall if it affects the working tree.

I remember practicing a question like this, and I think "git revert HEAD" is the one that just creates a new commit.

Ah, I got it! The question is asking for a command that reverses the last commit without changing the index or working tree. That means it has to be git revert HEAD. Option A is the answer.

I've seen this type of question before. I think the key is to understand that we want to reverse the last commit without affecting the index or working tree. That points me towards option C - git reset --soft HEAD^.
