此命令将获取Git父提交哈希：

git log -n 2 <commit-hash>

之后，gitdiff工具<commithash><parentcommithash>

例子：

bonnie@bonnie ~/ $ git log -n 2 7f65b9a9d3820525766fcba285b3c678e889fe3

CSS changed to maintain the aspect ratio of the channel logos and to fit them properly.

The ratio of the height to width of the channel images are maintained.

在此之后

git difftool 7f65b9a9d3820525766fcba285b3c678e889fe3b c3a61f17e14e2b80cf64b172a45f1b4826ee291f

git difftool COMMIT^ <commit hash>

如果您配置了difftool，也可以使用。

请参阅此处如何配置difftool。或此处的手册页。

此外，您可以使用git diff树--no commit id--name only-r＜commit hash＞来查看在给定的提交哈希中更改/提交了哪些文件。

您可以使用git diff HEAD HEAD ^1查看与父提交的差异。

如果您只想查看文件列表，请添加--stat选项。

从git diff（1）的手册页：

git diff [options] [<commit>] [--] [<path>…]
git diff [options] --cached [<commit>] [--] [<path>…]
git diff [options] <commit> <commit> [--] [<path>…]
git diff [options] <blob> <blob>
git diff [options] [--no-index] [--] <path> <path>

使用中间的第三个：

git diff [options] <parent-commit> <commit>

同样从同一手册页底部的示例部分：

$ git diff HEAD^ HEAD      <3>

比较上次提交和上次提交之前的版本。

诚然，它的措辞有点混乱，但也不会那么混乱

将最近的提交与之前的提交进行比较。

还可以查看特定文件的两次提交之间的更改。

git diff <commit_Id_1> <commit_Id_2> some_dir/file.txt

以下代码将显示当前提交

git show HEAD
