I have two files that when I compare with diff show that every line has changed. When I compare them with
diff -w (ignoring whitespace) it shows the few minimal changes that I expect.
Obviously there is some difference between the whitespace in each file, but I don't know what they are or how to find them. I have tried editing the files to ensure that the whitespace is actually space characters (as opposed to tabs) but am unsure what else to do.
I have used vim with
:set list on to confirm there was no trailing space at the end of the lines.
I also believe that each file has Linux line terminators as vim didn't show the
^M at the end of the lines.
