compares three versions of a file, and prints disagreeing ranges of text flagged with these codes: all three files differ file1 is different file2 is different file3 is different The type of change required to convert a given range of a given file to some other is indicated in one of these ways: Text is to be appended after line number n1 in file f, where f = or Text is to be changed in the range line n1 through line n2. If n1 = n2, the range can be abbreviated to n1. The original contents of the range follows immediately after a indication. When the contents of two files are identical, the contents of the lower-numbered file is suppressed. Produces a script for the editor that can be used to incorporate into file1 all changes between file2 and file3 (see ed(1)); i.e., the changes that normally would be flagged and Produces a script to incorporate only changes flagged Produces a script to incorporate only changes flagged Produces a script that will incorporate all changes between file2 and file3, but treat overlapping changes (that is, changes that would be flagged with in normal listing) differently.
