1. Make sure you're on the master branch

git checkout master

2. View your branches

git branch

3. Delete a branch

Assuming there's a branch, delete it:

git branch -d <your_github_username>-asks-a-question

If it's fully merged into master then it will be deleted. If not, you'll get an error like:

error: The branch '<your_github_username>-asks-a-question' is not fully merged.
If you are sure you want to delete it, run 'git branch -D <your_github_username>-asks-a-question'.

Donal says: Be very careful using the branch -D command as you can lose commits (actually, it maybe possible to retrieve them by inspecting the git reflog).
