🚀 Advanced Git Techniques
Mastering power tools and recovery for complex scenarios.
In This Lesson
Interactive Rebase: Rewriting History
Interactive rebase is a powerful tool to reorganize, edit, and clean up your commit history before sharing it. Use it to squash related commits into one for a cleaner project history.
🔑 Key Insight: The Golden Rule of Rebasing
Never rebase a branch that has been pushed to a remote repository and is shared with other developers. Rebasing rewrites history, which causes major confusion for anyone else working on that branch.
Git Bisect
git bisect uses binary search to quickly find the commit that introduced a bug.
Git Reflog
git reflog keeps a record of where your branch HEAD has been. It's the ultimate "undo" button for Git, allowing you to recover commits that seemed "lost."
💡 Pro Tip: Reflog to the Rescue
Did you accidentally force-push, delete a branch, or rebase into a mess? Don't panic. Check git reflog. It often holds the reference to the commit you need to get back to.
Git Hooks
Hooks are scripts that run automatically at key points in the Git process (pre-commit, post-receive, etc.) to automate tasks like linting.
Reset Strategies
Understand the difference between --soft, --mixed (default), and --hard resets to manage your staging area and working directory safely.
Git Stash
git stash allows you to temporarily set aside uncommitted changes when you need to switch tasks quickly.
Submodules
Git submodules allow you to keep another Git repository as a subdirectory of your current project.
Recovery Scenarios
Beyond reflog, consider tools like git fsck to find dangling objects.
Git Worktrees
Worktrees allow you to have multiple branches checked out in different directories simultaneously.
Performance Optimization
For large repositories, use git gc to optimize the database.
