What is Git HEAD@{x}

Question

I saw code examples using HEAD@{1}.

While reading about HEAD I saw the difference between HEAD~ and HEAD^ but what does this mean or where can I read more about the HEAD@?

Answer 1

HEAD@{1} is the reference before HEAD@{0} (which is the current HEAD).

Everything you're looking for can be found in the gitrevisions documentation. Additionally the git reflog documentation should be helpful too.

Answer 2

Git logs every change to HEAD in what is called reflog. Run git reflog to see. The HEAD@{x} will refer to the commit in that log.
