更新:查尔斯·贝利的答案是正确的;所需的功能已经内置到git中。

我将把这个答案留在这里，因为它可能为git中没有内置的东西提供一些想法。

Git diff通过比较/dev/null来显示新建和删除的文件写一些东西(我自己用Perl)来查找/dev/null并过滤掉下面的行直到下一个diff，然后git diff…|过滤器。

重命名文件是另一回事;我(还)没有一个很好的答案。

——diff-filter选项同时适用于diff和log。

我经常使用——diff-filter=M，这将diff输出限制为仅对内容进行修改。

要检测重命名和副本并在diff输出中使用它们，您可以分别使用-M和-C，以及R和C选项来——diff-filter。

官方文档:

--diff-filter=[(A|C|D|M|R|T|U|X|B)…​[*]] Select only files that are Added (A), Copied (C), Deleted (D), Modified (M), Renamed (R), have their type (i.e. regular file, symlink, submodule, …​) changed (T), are Unmerged (U), are Unknown (X), or have had their pairing Broken (B). Any combination of the filter characters (including none) can be used. When * (All-or-none) is added to the combination, all paths are selected if there is any file that matches other criteria in the comparison; if there is no file that matches other criteria, nothing is selected. Also, these upper-case letters can be downcased to exclude. E.g. --diff-filter=ad excludes added and deleted paths.

示例:只显示添加、修改、修改的文件，不显示删除的文件:

git diff --diff-filter=ACM

此外，可以将这些大写字母小写以排除在外。 例如——diff-filter=ad排除添加和删除的路径。

在你的情况下，git diff——diff-filter=ad可以工作，但请确保不要在同一个过滤器中使用小写字母和大写字母，除非你有git 2.36 (Q2 2022)。

"git diff——diff-filter=aR"(man)现在正确解析。

The --diff-filter=<bits> option allows to filter the diff by certain criteria, for example R to only show renamed files. It also supports negating a filter via a down-cased letter, i.e. r to show everything but renamed files. However, the code is a bit overzealous when trying to figure out whether git diff(man) should start with all diff-filters turned on because the user provided a lower-case letter: if the --diff-filter argument starts with an upper-case letter, we must not start with all bits turned on. Even worse, it is possible to specify the diff filters in multiple, separate options, e.g. --diff-filter=AM [...] --diff-filter=m. Let's accumulate the include/exclude filters independently, and only special-case the "only exclude filters were specified" case after parsing the options altogether.
