> I don’t quite follow. Do you mean the “.*”, so you replace .* with .? Yes. Based on the explanation of '*' in the gawk manual, it's used to match zero/one/more times repeating of the preceding character which in turn doesn't match the default diff printing mode( >for removing, <for adding). It's not necessary to add '*' to '/^>.*(=|Linux)/'.
