remove this "do"

It's a syntax error, as correctly identified.
Syntax of "while" expression is:
  
  while <condition>
    <expressions>
  end

Your example:

  while 1
    f.each do |i|
       # do something with i and eventually break
    end
  end

or:

  loop do
    f.each do |i|
       # do something with i and eventually break
    end
  end

HTH,
