There's also the flip flop operator:

File.foreach "myfile" do |line|
   if /pattern/ =~ line .. false
     puts line
   end
end

The trick I am using is that the FF operator starts to return true if 
the first expression returns true and stays true until the last 
expression returns true - in this case never since you want to read 
until the end of the file.

Kind regards
