It performs word-by-word comparison of one or multiple pair(s) of plain-text-files, in very much the same way as the UNIX wdiff() utility. Results are stored as color-marked difference-files in HTML-format, or in PDF-format if option -p is given.

A difference-file is a unification of the two input text-files, preserving original text sequence. Text present in both files is printed in black. (Groups of) words locally missing in one of the two files are color-marked as follows:

- bolt red text is present in the 1st file, and not present (there) in the 2nd file; - bolt green text is present in the 2nd file and not present (there) in the 1st file;

With option -d, wordif.sh acts on two directories instead of two text-files. It then compares each text-file in the 2nd directory to its associated text-file in the 1st directory. The resulting difference-files are collected in a difference-directory.

To correctly associate two files in either directory to each other, their respective file names must start with same unique number, followed by an underscore.
