差异文件存在于两个不同的目录中 [英] Diff files present in two different directories

问题描述

我有两个目录具有相同的文件列表。我需要使用 diff 命令比较两个目录中存在的所有文件。是否有一个简单的命令行选项可以执行此操作，还是我必须编写一个Shell脚本来获取文件列表，然后遍历它们？

I have two directories with the same list of files. I need to compare all the files present in both the directories using the diff command. Is there a simple command line option to do it, or do I have to write a shell script to get the file listing and then iterate through them?

推荐答案

您可以为此使用 diff 命令：

diff -bur folder1/ folder2/

这将输出忽略空格的递归diff，并带有统一上下文：

This will output a recursive diff that ignore spaces, with a unified context:

• b 标志意味着忽略空格


• u 标志表示统一的上下文（前后3行）


• r 标志表示递归

• b flag means ignoring whitespace
• u flag means a unified context (3 lines before and after)
• r flag means recursive
