; KillDupes - adidos - 08.15.02
; Usage: /killdupes <C:\Path\To\File.txt>
; KillDupes sorts (alphabetically) and removes duplicate lines in a text file.
; It took only 6.5s to kill 550 dupes from a 1750 line file on my computer!
; Very useful for proxy lists, names, and anything else you can think of.
; I tried to do a 650kbyte file (which has over 30,000 lines) but it took over
; 5 minutes so I ended the loop (control + break).
; I suggest you don't use this for HUGE files such as the one I tried, but it
; is great for files under 100kbytes.
