unix diff命令问题
我有两个文件。我想使用 diff 来比较它们，看看发生了什么变化。 我检查了 man diff 但有选项日志。谁能给我一个快速提示我应该做什么？ 谢谢大家！！

将以统一的形式为您提供文件之间的差异。您还可以将它们保存到文件中
并修补原始文件以进行以下更改：
will give you a differences between files in unified form. You can also save them to a file
And patch an original file to have these changes:
简单：
差异路径/to/file1 路径/to/file2Simple:
diff path/to/file1 path/to/file2
