Overview
This sequence combines several important Git features that you’ll use regularly: grabbing specific commits, juggling commits to reorder them, creating tags for milestones, and using git describe to find your position in history.Levels in This Sequence
1. Grabbing One Commit
What you’ll learn: How to isolate and move a single specific commit. Key concepts:- Sometimes you just need one commit from a branch
- Use
cherry-pickorrebase -ito grab specific commits - Useful when you made commits on the wrong branch
- Helps keep commit history clean
2. Juggling Commits
What you’ll learn: How to reorder commits and make changes to earlier commits. Key concepts:- Sometimes you need to modify commits that aren’t the most recent
- Use
rebase -ito reorder commits - Can use
--amendto modify the currently checked-out commit - Combine these techniques to edit commit history
This pattern is common when you realize you need to fix something in an earlier commit before continuing work.
3. Juggling Commits #2
What you’ll learn: Advanced commit reordering with cherry-pick. Key concepts:- Cherry-pick can solve commit juggling problems
- You can specify exact commit order
- Useful when you know exactly what you want
- Often cleaner than interactive rebase for simple reordering
4. Git Tags
What you’ll learn: How to create permanent markers in your commit history. Key concepts:- Tags permanently mark specific commits as milestones
- Unlike branches, tags never move
- Used for releases, major milestones, etc.
- You can checkout tags like commits (enters detached HEAD)
- Can reference tags in other commands
5. Git Describe
What you’ll learn: How to describe your position relative to the nearest tag. Key concepts:git describehelps you see where you are in history- Output format:
<nearest-tag>_<numCommits>_g<hash> - Shows closest tag, number of commits since tag, and abbreviated hash
- Useful for versioning and understanding your location
If there are no tags in your repository, git describe will fail. Always tag your releases!
Common Patterns
Here are some practical scenarios where these techniques shine:Pattern 1: Fix a Commit in the Middle
Pattern 2: Mark and Find Releases
Pattern 3: Cherry-pick from Another Branch
Commands Reference
| Command | Purpose | Example |
|---|---|---|
git cherry-pick <commit> | Copy specific commits | git cherry-pick C2 C4 |
git rebase -i <location> | Interactive reorder commits | git rebase -i HEAD~3 |
git commit --amend | Modify the last commit | git commit --amend |
git tag <name> <commit> | Create a tag | git tag v1 C1 |
git describe <ref> | Describe position | git describe main |
