I know on windows allows you to run batch files without actually logging into the OS. This allows you to put an base image onto a PC and use batch files to change settings, place on active directory, and other things without having to log in. How do I do this with a mac? I want to be able to run 2 command line commands, one after the other once the other is finished, and then add it to Active directory. Would I do this in perl? and how do I get it to run without logging in so I can start it and then move on to other stuff?
