- "GNU Diffutils is a package of several programs related to finding
-differences between files.
-
-Computer users often find occasion to ask how two files differ. Perhaps one
-file is a newer version of the other file. Or maybe the two files started out
-as identical copies but were changed by different people.
-
-You can use the diff command to show differences between two files, or each
-corresponding file in two directories. diff outputs differences between files
-line by line in any of several formats, selectable by command line
-options. This set of differences is often called a ‘diff’ or ‘patch’. For
-files that are identical, diff normally produces no output; for
-binary (non-text) files, diff normally reports only that they are different.
-
-You can use the cmp command to show the offsets and line numbers where two
-files differ. cmp can also show all the characters that differ between the
-two files, side by side.
-
-You can use the diff3 command to show differences among three files. When two
-people have made independent changes to a common original, diff3 can report
-the differences between the original and the two changed versions, and can
-produce a merged file that contains both persons' changes together with
-warnings about conflicts.
-
-You can use the sdiff command to merge two files interactively.")
