  Diff - Wikipedia, the free encyclopedia
McIlroy's work was preceded and influenced by Steve Johnson's comparison program on GECOS and Mike Lesk's proof program.
The potential usefulness of a diff tool provoked McIlroy into researching and designing a more robust tool that could be used in a variety of tasks but perform well in the processing and space limitations of the PDP-11's hardware.
McIlroy considered writing a post-processor for diff where a variety of output formats could be designed and implemented, but he found it more frugal and simpler to have diff be responsible for generating the syntax and reverse-order input accepted by the ed command.

 Spellchecking by computer
For example, instead of holding doubt, doubts, doubted and doubting, they hold just doubt and use a set of rules to remove suffixes before looking words up; given doubting, the checker would remove the ing and look up the doubt.
A second way to save storage space is to hold the dictionary as a bit map (McIlroy 1982, Nix 1981).
