git clean - Git checkout/pull doesn't remove directories?

Question

I've got my repo @ github. I did some work at home and pushed it to github. It involved some deleting of files and directories. Now I'm on my work box, which had a copy of the code before deleting the files and directories.

I issued the following:

git remote update
git checkout HEAD
git pull origin HEAD

It deleted all of the files it should have, but not the directories the files were in.

Two questions:

1. Why did it not remove the directories?
2. Is there a git command I can issue in the current state to remove them?

Answer 1

Git doesn't track directories, so it won't remove ones that become empty as a result of a merge or other change. However, you can use git clean -fd to remove untracked directories (the -fd flag means force removal of untracked files and directories).
