DW(1L) DW(1L) 08 April 1991 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). AUTHOR Nelson H. F.
