    Your loop answer is one of the ugliest I've ever seen (no offense). If you just want to put the content of a file in an array, please consider using mapfile instead; or at least, don't use eval since read (or even printf) will happily set an array field for you. Also, remove the function keyword when you're defining a function ;). Commented Nov 8, 2014 at 13:43
