Subject: Re: Navigating Files by Line Number

That seems to fit with the ri description of File.lineno=.  It sets
lineno but doesn't seem to seek to that line in the file.  I think
what you want could be achieved by:

f.rewind
1.upto(9) { f.readline }

or even extending the File class to add a function that does this

Class File
  def seek_line(line)
     self.rewind
     1.upto(line) { self.readline }
  end
end

Cheers,
Jason
