git diff HEAD：是查看 workspace 和 local repository 的差别的。

git diff：是查看 workspace 与 index 的差别的。 git diff --***d：是查看 index 与 local repositorty 的差别的。 git diff HEAD：是查看 workspace 和 local repository 的差别的。（HEAD 指向的是 local repository 中最新提交的版本）

贴一下 manpage 标答

Various ways to check your working tree

$ git diff (1)
$ git diff --***d (2)
$ git diff HEAD (3)

1. Changes in the working tree not yet staged for the next commit.
2. Changes between the index and your last commit; what you would be committing if you run "git commit" without "-a" option.
3. Changes in the working tree since your last commit; what you would be committing if you run "git commit -a"

Comparing with arbitrary commits

$ git diff test (1)
$ git diff HEAD -- ./test (2)
$ git diff HEAD^ HEAD (3)

1. Instead of using the tip of the current branch, compare with the tip of "test" branch.
2. Instead of comparing with the tip of "test" branch, compare with the tip of the current branch, but limit the comparison to the file "test".
3. Compare the version before the last commit and the last commit.
