wdiff: wdiff (display word differences between text files) wdiff: wdiff: The GNU wdiff program is a front end to diff for comparing files on wdiff: a word per word basis. A word is anything between whitespace. This is wdiff: useful for comparing two texts in which a few words have been changed wdiff: and for which paragraphs have been refilled. It works by creating wdiff: two temporary files, one word per line, and then executes diff on wdiff: these files. It collects the diff output and uses it to produce a wdiff: nicer display of word differences between the original files. wdiff: wdiff:
