What is the purpose of "@" in Git command log output?

What is the relationship between "@" and HEAD in Git command?

- "@" is a shorthand notation that can be used to refer to the current commit. It is commonly used in commands like git show @ to show the changes in the current commit.
- HEAD is a reference to the current branch or the last commit on the current branch. It points to the most recent commit on the current branch and can be used in commands like git checkout HEAD to switch to the state of the repository at the current commit.
In summary, both "@" and HEAD can be used to refer to the current commit in a Git repository, with "@" being a shorthand notation and HEAD being a more explicit reference to the current branch or commit.
