 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.

 SEE ALSO
      awk(1), lex(1).
