您可以使用foldername或foldername/*。无论哪种方式都应该有效。

git log -- path/to/folder
git log -- path/to/folder/*

此方法不会跟踪重命名文件的历史记录。

请注意，这--也是可选的。（来自 git log 手册）

[--] <path>...

           Show only commits that are enough to explain how the files that match the specified paths came to be. See History Simplification below for
           details and other simplification modes.

           Paths may need to be prefixed with -- to separate them from options or the revision range, when confusion arises.
