nope
That's not what I want either. Both those functions output the entire line when there has been a single change to it. If I have two files like this:
File 1:
aaaaaaaa2
aaaaaaaa3
aaaaaaaa9
aaaaaaaa4
aaaaaaaa4
and File 2:
aaaaaaaa8
aaaaaaaa4
aaaaaaaa3
aaaaaaaa7
aaaaaaaa7
I'd like my output to be something like
<2
>8
<3
>4
<9
>3
<4
>7
<4
>7
so as to avoid having to deal with all those "a"s
