Knowledge is Power: Getting out of Trouble by Understanding Git
summary
Explains Git as blobs, trees and commits and shows concrete commands to fix real breakage: creating a repo with git init, recovering from a destructive git reset --hard by using git reflog to find the lost hash, running git gc --prune=all implications for object lifetime, using git hash-object -w plus a tag and git cat-file to hide and retrieve blobs, automating regression hunting with git bisect, and using git rebase --exec to run tests while replaying commits.
