10.times do |i|
  begin
    puts "reading file #{i}"

    if i == 4
      raise "error reading file #{i}"
    end

  rescue RuntimeError => msg
    puts msg
    next
  end
end

--output:--
reading file 0
reading file 1
reading file 2
reading file 3
reading file 4
error reading file 4
reading file 5
reading file 6
reading file 7
reading file 8
reading file 9
