1971Unix cmp: compare two files and it reports where they differ and the differing words. Unix First Edition, Bell Labs.
See also: Unix diff, line by line: manual page dated 15 May 1974.
“The two files are compared for identical contents. Discrepancies are noted by giving the offset and the differing words.”
diff (1974) shows how two files differ line by line; cmp, two and a half years earlier, already listed where and how they differ, word by word.
