Q. You told Git your name and email, but where does Git save that information? See if you can locate where this is.
A: It’s at the root of your ~ (i.e. home) folder; file .gitconfig.
Q. Git is known as the stupid content tracker. What git help page says this?
A: It’s the first item of the man page.
Q. What is the Git command that forward-ports local commits?
A: git-rebase - Forward-port local commits to the updated upstream head
Q. What does the abbreviation DAG stand for, in the context of Git?
