Undo a git merge (hasn't been pushed yet)

Question

I just committed some changes into one of my feature branches (\"feedback_tab\") then, checked out \"master\" and merged them in there. I actually meant to merge them into my \

Answer 1

To undo a merge that was NOT pushed:

git reset --merge ORIG_HEAD

If during the merge you get a conflict, the best way to undo the merge is:

git merge --abort

Answer 2

This one will surely work!

git reset --hard HEAD~1 
git init

The first one will revert the changes you recently made (the merge) the second will init the repo to latest (therefore will fast forward to latest on origin)

I've tried

git reset --merge

but it didn't do the trick.

Answer 3

Taken from git reset

Undo a merge or pull

    $ git pull                         <1>
    Auto-merging nitfol
    CONFLICT (content): Merge conflict in nitfol
    Automatic merge failed; fix conflicts and then commit the result.
    $ git reset --hard                 <2>
    $ git pull . topic/branch          <3>
    Updating from 41223... to 13134...
    Fast-forward
    $ git reset --hard ORIG_HEAD       <4>

Answer 4

git reset --hard HEAD~17 takes you back 17 commits ahead of the head of master. git rebase -i HEAD~17 probably gets rid of the extra commits as well.
