当我执行gitdiffCOMMIT时,我看到了提交和HEAD之间的变化(据我所知),但我希望看到单个提交所做的变化。

我还没有在diff/log上找到任何明显的选项来提供输出。


当前回答

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。

其他回答

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。

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。

一些答案漏掉了一个特例。如何查看根提交所做的更改,因为它没有父/祖先。

Both

git diff<root_commit>^<root_commit>

and

git diff<root_commit>~<root_commit>

抛出错误。

$git diff 27e521ca73a46b2d3a28568dc49fced81e46aaea~ 27e521ca73a46b2d3a28568dc49fced81e46aaea
fatal: ambiguous argument '27e521ca73a46b2d3a28568dc49fced81e46aaea~': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'

git diff<root_commit>^!

显示diff btw根提交和HEAD。像这样:

$ git diff 27e521ca73a46b2d3a28568dc49fced81e46aaea^!
diff --git a/file1.txt b/file1.txt

(这些是所有提交对我的根提交和HEAD所做的更改)。

对于根提交

我只发现

git show--color--prett=格式:%b<root_commit_hash>

作品

像这样:

$ git show --color --pretty=format:%b 27e521ca73a46b2d3a28568dc49fced81e46aaea

(我的根提交仅添加了README)

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

我在windows 10上运行的是Git 2.6.1.windows.1版本,所以我需要对Nevik的答案稍作修改(用波浪号代替插入符号):

git diff COMMIT~ COMMIT

另一个选项是引用插入符号:

git diff "COMMIT^" COMMIT
