NAME

dw - find duplicate words

SYNOPSIS

dw < infile >outfile

dw filters its standard input, printing on standard output only those words which appear twice in succession. Each word is prefixed by its line number(s).

A word starts with a letter or underscore, and is followed by zero or more letters, underscores, or digits. Letter case is ignored.

This is a handy tool for finding a common typographical error in documentation.

Its other purpose is to demonstrate a reasonably short lex(1) program.
