I forgot a file

You will learn: how to add a forgotten file to your last commit.

The problem

You committed your day 2 page. But its style file is still on your desk! This happens to everyone. Here’s the safe way out.

Try it

You haven’t pushed yet. What’s the neatest fix?

Try it

First, git add day2.css puts the file in the box. Now build the command that tucks the box into your last commit.

Tap the pieces in the right order.

…

Try it

Now do it for real. Add day2.css to the last commit.

Check with git show --stat. Both files sit in one commit. Same message as before.

Predict

New story: you had pushed the commit already. What now?

You did it!

You can now add a forgotten file to your last commit.

Go deeper (optional)

Amend makes a brand-new commit with a new hash. That is why it’s only for commits you haven’t pushed. Forgot a file several commits ago? Just commit it now with a clear message. Simple wins.
