Differences for a certain folder between git branches
提问by Wazery
As in the title, I want to have a diff file for a certain folder between the master branch and a branch I have created.
如标题所示，我希望在 master 分支和我创建的分支之间的某个文件夹中有一个 diff 文件。

You can use
您可以使用
git diff master..yourbranch path/to/folder
回答by Sergiu Dumitriu
git diffcompares trees (as in hierarchies of source files at two different points in time), so it can't extract the changes done by a certain author. If you want to see what changes a user committed, then you need git log.
git diff比较树（如在两个不同时间点的源文件层次结构），因此它无法提取某个作者所做的更改。如果您想查看用户提交的更改，那么您需要git log.
Does this solve your need?
这能解决您的需求吗？
git log --author=jdoe oldbranch..newbranch -p -- path/to/subdirectory > myChangesInSubdirectory.patch
This lists each commit done by jdoebetween the two commits, printing them as a patch instead of the usual commit summary, limiting only to commits that have changes in the target subdirectory, and redirects the output to a file.
这列出了jdoe在两次提交之间完成的每个提交，将它们打印为补丁而不是通常的提交摘要，仅限于在目标子目录中有更改的提交，并将输出重定向到文件。
