比较文件时如何忽略行尾？ [英] How can I ignore line endings when comparing files?

问题描述

我正在比较两个文本文件，得到以下结果：

I am comparing two text files and I get the following result:

diff file1 file2 | grep 12345678

> 12345678
< 12345678

如您所见，两个文件中都存在相同的字符串，并且两个文件都用 sort 。

As you can see, the same string exists in both files, and both files were sorted with sort.

这里的行尾必定会造成麻烦（Windows与Unix）。

The line endings must be getting in the way here (Windows vs. Unix).

是有没有办法让 diff 忽略Unix上的行尾？

Is there a way to get diff to ignore line endings on Unix?

推荐答案

使用-strip-trailing-cr 选项：

diff --strip-trailing-cr file1 file2

该选项导致 diff 剥离在比较文件之前，尾随回车符。

The option causes diff to strip the trailing carriage return character before comparing the files.
