What does the caret (^) character mean in Git?
git
Solution
`HEAD^` means the first parent of the tip of the current branch.
Remember that git commits can have more than one parent. `HEAD^` is short for `HEAD^1`, and you can also address `HEAD^2` and so on as appropriate.
You can get to parents of any commit, not just `HEAD`. You can also move back through generations: for example, `master~2` means the grandparent of the tip of the master branch, favoring the first parent in cases of ambiguity. These specifiers can be chained arbitrarily , e.g., `topic~3^2`. See related answer to What’s the difference between `HEAD^` and `HEAD~` in Git?
For the full details, see the “Specifying Revisions” section of `git rev-parse --help`.
Problem
I saw an answer to a question here that helps restore a deleted file in git. The solution was ``` git checkout <deleting_commit>^ -- <deleted_file_path> ``` What does the caret character (`^`) do? I’ve seen it elsewhere doing very useful things in git. It’s magical. Someone please spoil it for me and tell me what it does?
