+You should work through linkgit:gittutorial[7] before reading this tutorial.
The goal of this tutorial is to introduce two fundamental pieces of
git's architecture--the object database and the index file--and to
characters to save yourself typing all 40 hex digits:

committer J. Bruce Fields <bfields@puzzle.fieldses.org> 1143414668 -0500
and the "parent" object refers to the previous commit:

-a", which creates a commit including every change you've made to
your working tree. But what if you want to commit changes only to
certain files? Or only certain changes to certain files?
head still doesn't contain the new line:

The thing that it's comparing against is actually the index file,
which is stored in .git/index in a binary format, but whose contents
we can examine with ls-files:

a reference to it in the index file. If we modify the file again,
we'll see that the new modifications are reflected in the "git-diff"
output:

the -a option), and verify that the state committed only includes the
changes stored in the index file, not the additional change that is
still only in our working tree:

the working tree; the -a option to commit tells it to first update
the index with all changes in the working tree.

In addition to being the staging area for new commits, the index file
is also populated from the object database when checking out a
branch, and is used to hold the trees involved in a merge operation.
