脚本宝典收集整理的这篇文章主要介绍了linux 比较两个文件夹diff不同 (diff命令, md5列表)，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。

比较文件夹diff，可以直接使用diff命令

[root@~]# diff -urNa dir1 dir2
　　-a Treat all files as text and compare them line-by-line, even if they do not seem to be text.
　　-N, --new-file
　　　　In directory comparison, if a file is found in only one directory, treat IT as PResent but empty in the other directory.
　　-r When comparing directories, recursively compare any subdirectories found.
　　-u Use the unified output format.

比较文件夹diff，也可以比较文件MD5列表。下面命令可以获取文件夹中文件md5列表

find /home/ -tyPE f -not \( -name '.*' \) -exec md5sum {} \;
