To make the list easier to read, I want to *delete* the duplicate lines. A good example is a list of files that have errors (maybe excerpted from an application sever's log files). In that case you have a newline-delimited list of file paths, and depending upon the situation, the same file path might be listed 4 or 5 times or more. Often, it is useful to have a list of just the files that are faulty, which can be produced by deleting all the duplicate lines. This script is for filtering just those kinds of list files. [Of course,](http://xkcd.com/378/ "emacs has a command for that") for **Emacs** users [there is a much easier way to remove duplicate lines:](http://everything2.com/title/useful%2520emacs%2520lisp%2520functions "useful emacs lisp functions"), if you have `uniq` installed on your system. `M-x sort-lines RET C-x h M-x shell-command-on-region RET uniq RET`
