puts IO.read("data2")
Nashville
Orlando
Tampa
Memphis
    ==>nil

p IO.readlines("data2")
["Nashville\n", "Orlando\n", "Tampa\n", "Memphis\n"]
    ==>nil

p IO.readlines("data2").map{|s| s.strip}
["Nashville", "Orlando", "Tampa", "Memphis"]
    ==>nil

p IO.read("data2").split( /\s*\n\s*/ )
["Nashville", "Orlando", "Tampa", "Memphis"]
    ==>nil
