diff command ignoring new file in the new directory
提问by user1427180
I added a new file in "modified directory" (in 3rd sub level folder) and when i try to generate the patch file using the following command it appears that diff command is ignoring the new file:
我在“修改后的目录”（在第三个子级别文件夹中）添加了一个新文件，当我尝试使用以下命令生成补丁文件时，diff 命令似乎忽略了新文件：
diff –ur "original directory" "modified directory" > version1.patch
I appreciate your help..
我感谢您的帮助..

You also need -Nflag. From man diff:
您还需要-N标志。来自man diff：
-N --new-file
Treat absent files as empty.
When generating patches, the "standard" diff flags are -Npur. You've already discovered why you need -N; -pmakes the patch easier for humans to read.
生成补丁时，“标准”差异标志是-Npur. 你已经发现你为什么需要-N；-p使补丁更易于人类阅读。

Try with this command,
试试这个命令，
diff -RuN "original directory" "modified directory" > version.patch
diff -Run “原始目录” “修改后的目录” > version.patch
