Hibernate

This Bash Script will hibernate your PC after specified time in minutes. 
Okay, you're must be wondering what for? When I go to bed, I like to leave my laptop playing my favorite music as I sleep off. 
So, I need it to hibernate after say 1 hour, so that the battery is not drained or doesn't suddenly shutdown. Yeah, certainly not for everyone!
