git --all missing commit

Question

Can someone please help me understand what\'s happening here?

I start with git log --oneline, which spits out:

4df9421 (HEAD, master) mo         


        

Answer 1

It is missing, because it isn't reference anymore by HEAD or by a branch.
You have reset both (HEAD and master) to another commit, with your git reset --hard.

Only git reflog would show you that recent commit.

git log --all is only for listing commits referenced in refs/ (like tags, heads, ...)

--all

Pretend as if all the refs in refs/ are listed on the command line as .
