Question

I just did:

git reset --merge

and I lost my latest modifications to some files, how do I undo this last action?

Answer 1

you can look at your reflog to find the commit at wich you were before:

git reflog

Once you find your previous commit, copy the sha-1 hash and

git reset <commit sha-1> --hard

Although, if what you lose was uncommitted modifications, well then they’re lost.
