I want to learn Unix on OS X Lion and AppleScripts very well. I've been a Mac user since Tiger OS X, but now I've decided to be serious about Unix and AppleScript. Can anybody recommend good books for this purpose. I would like to have books which start from basics but later go on to great details to fully explore these two things. I really need expert opinion here, plz.
