How to ignore line endings when comparing files?

问题

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

diff file1 file2 | grep 12345678

> 12345678
< 12345678

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

The line endings must be getting in the way here (windows vs unix).

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

回答1:

Use the --strip-trailing-cr option:

diff --strip-trailing-cr file1 file2

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