What do these arguments mean in the "git-checkout" command?

Question

I have the following command in Git to recover a file:

git checkout (hash-commit)^  --(caminho-arquivo)

In this command what the ^ and --?

Answer 1

The ^ indicates that you want the commit a level above this specified. It is the same as ^1, If you wanted 2 levels above would use ^2.

The -- indicates that you will pass a subcommand, an argument of what you will do with the main command.
