Subject: A simple newbie question (arrays and strings)

Today I started programming in ruby.
Here's what I managed to do so far:

string = Dir.entries(".")
string.delete_at(0)
string.delete_at(0)

1. I get a list of files
2-3. I delete the first two elements ('.' and '..')

Now my files are all like "something - some other thing"
I want to split them:

string.each do |s|
puts s.split("-")[0]
end

So it outputs the "something" part in my filenames.
Now I'd like to remove duplicate entries (.uniq method right?).
Can it be done in a single line? If not, how do i get an array 
containing only the "something" part to work on with .uniq?

I tried with some loops, to create a new array with the splitted string 
in it, but my PHP approach doesn't work:
i = 0
for i in string
splitted[i] = i.split("-")[0]
i += 1
end

Thank you!
