Subject: loop starting not from beginning

Hi Ruby friends,

I have lots of file loops w the ff form:

File.open("test") do |f|
	f.each do |line|
	   p line
	end 
end


However, the file has headers that I want to skip. So I skip first few line
of headers like ...

scheme 1:

File.open("test") do |f|
	f.each do |line|
         if f.lineno <= 5 then next end
	   p line
	end 
end

or 

scheme 2:

File.open("test") do |f|
   	f.readline	<---- just read
	f.readline
	f.each do |line|
	   p line
	end 
end


and I combine scheme 1 & 2 like:

File.open("test") do |f|
    while (f.lineno <= 4) 
          f.readline 
    end
    f.each do |line|
	 p line
    end 
end


Is there any other way better than this?
I like something that when it opens, its already on the line that I want...
or maybe, I'm asking too much.. I'm just newbie, so pls bear w me..

Many thanks,
