使用 shell 脚本比较 2 个文件
我试图找到知道两个文件是否相同的方法，并发现了这篇文章...
我在第一个答案中使用了代码，但我认为它不起作用，或者至少我无法让它正常工作......
我什至尝试制作一个文件的副本和比较两者（副本和原始），我仍然得到答案，就好像它们不同一样，而实际上它们不应该不同。
有人可以帮我一下，或者解释一下发生了什么吗？
非常感谢;

I was trying to find the way for knowing if two files are the same, and found this post...
Parsing result of Diff in Shell Script
I used the code in the first answer, but i think it's not working or at least i cant get it to work properly...
I even tried to make a copy of a file and compare both (copy and original), and i still get the answer as if they were different, when they shouldn't be.
Could someone give me a hand, or explain what's happening?
Thanks so much;

您是否试图比较两个文件是否具有相同的内容，或者您是否试图查找它们是否是同一文件（两个硬链接）？
如果您只是比较两个文件，请尝试：
或
以查看假定的差异。
您还可以尝试
md5sum：如果两个文件返回相同的校验和，则它们是相同的。
Are you trying to compare if two files have the same content, or are you trying to find if they are the same file (two hard links)?
If you are just comparing two files, then try:
or
in order to see the supposed differences.
You can also try
md5sum:If both files return same checksum, then they are identical.
