First, you need to know what is meant by an interactive and a login shell. Basically, the shell is just there to take a list of commands and run them; it doesn't really care whether the commands are in a file, or typed in at the terminal. In the second case, when you are typing at a prompt and waiting for each command to run, the shell is interactive; in the other case, when the shell is reading commands from a file, it is, consequently, non-interactive. A list of commands used in this second way --- typically by typing something like zsh filename, although there are shortcuts --- is called a script, as if the shell was acting in a play when it read from it (and shells can be real hams when it comes to playacting). When you start up a script from the keyboard, there are actually two zsh's around: the interactive one you're typing at, which is waiting for another, non-interactive one to finish running the script. Almost nothing that happens in the second one affects the first; they are different copies of zsh.
