I deleted a branch

You will learn: how to bring back a branch you deleted by mistake.

The problem

You cleaned up branches with -D. Then you remember: about was never merged! Is your work gone? Breathe. This happens to everyone.

Try it

Deleting a branch only peels off its label. The commits stay for a while. The reflog: Git's diary of everywhere HEAD has been. remembers them.

Tap the line with your about page commit.

~/diary $ git reflog

0 of 1 found

Try it

Stick a new about label on that commit.

Predict

What does git branch -D really delete?

Check

Prevent it next time. Sort each fact.

Drag a card into a box. Or tap the card, then tap the box.

      You did it!

      You can now bring back a branch you deleted by mistake.

      Go deeper (optional)

      Look back at the hook. Git printed the old hash after the word was. git branch about plus that hash works too. Deleted the branch on GitHub as well? Its pull request page can often restore it.
