>From decvax!yale-comix!jre@Berkeley Thu Sep 24 15:17:30 1981 There is a much better algorithm for comparing files that is not only linear time/space, but also outputs differences in a way superior to DIFF. See "A Technique for Isolating Differences Between Files" by Paul Heckel, CACM April 1978. A good C programmer can implement the algorithm in a day. There are very successful versions running on TOPS-20 and the Apollo.
