duplicate lines

hello all,
i was wondering, i have a list of about 2,000 rows of text going down vertically,
but out of that 2,000 there's only about 1,500 actual items - the rest are duplicates.
how would i go about eliminating the duplicate strings of text quickly?
thanks much

thanks, that did the trick!
one more thing, sorry
any way to add a prefix/suffix to every item in a list?
i.e. for html formatting?

ahh sorry, i think i said that wrong...
here's what i have:
i got a list of about 1,000 numbers, all vertically down
how would i go about adding "<option>" before every number and "</option>" after every number?
thanks again!

what i have looks like:

5,366.43
7,384.87
9,114.63
11,614.75
5,367.38

what i'm trying to get to is:

<option>5,366.43</option>
<option>7,384.87</option>
<option>9,114.63</option>
<option>11,614.75</option>
<option>5,367.38</option>

rather then doing that manually a few thousand times, is there any way to automate that?
thnaks

thanks, that worked great!
