In git you always have some commit checked out. HEAD is a pointer to that commit and you’ll see HEAD used a lot in this zine. Like a branch, HEAD is just a text file. Run cat .git/HEAD or git status to see the current HEAD.
Examples of how to use HEAD:
- show the diff for the current commit:
git show HEAD
UNDO UNDO UNDO UNDO: reset branch to 16 commits ago
git reset --hard HEAD~16
(HEAD~16means 16 commits ago)show what’s changed since 6 commits ago:
git diff HEAD~6squash a bunch of commits together
git rebase -i HEAD~8
(this opens an editor, use “fixup” to squash commits together)
