What operating system and shell are you using?

Is this a homework assignment? We have seen a request similar to this recently, except that request was looking for words that only contained a single character instead of a repeated letter.

Please more clearly define exactly what you are trying to do. Every word in your sample text file has at least one letter that appears more than once. Are you saying that you want to remove every line from your text file?
