There were also quite a number of lower level plumbing commands that we encountered in the book.

The first one we encounter is ls-remote in ch06-github.html which we use to look at the raw references on the server.

We use ls-files in ch07-git-tools.html, ch07-git-tools.html and ch07-git-tools.html to take a more raw look at what your staging area looks like.

We also mention rev-parse in ch07-git-tools.html to take just about any string and turn it into an object SHA-1.

However, most of the low level plumbing commands we cover are in ch10-git-internals.html, which is more or less what the chapter is focused on. We tried to avoid use of them throughout most of the rest of the book.
