Fixing commit mistakes

In this activity, we will begin to explore some ways Git and GitHub can help us shape our project history.

Revising your last commit

git commit --amend allows us to make changes to the commit that HEAD is currently pointing to. Two of the most common uses are:

• Re-writing commit messages
• Adding files to the commit

Let's see this in action:

1. Create a new file:
   • Bash: touch file7.md
   • PowerShell: Out-File file7.md
2. When you are adding files to the previous commit, they should be in the staging area. Move your file to the staging area: git add file7.md
3. git commit --amend
4. The text editor will open, allowing you to edit your commit message.

You can actually amend any data stored by the last commit such as commit author, email, etc.
