The difference between an interactive shell and a non-interactive shell

The interactive mode is where the shell waits for your input and executes the commands you submit. This pattern is called interactive because the shell interacts with the user. This mode is also familiar to most users: Log in, execute some commands, and check back. When you sign back, the shell also terminates.
The shell can also run in a different mode: non-interactive mode. In this mode, the shell does not interact with you, but instead reads the commands stored in the file and executes them. When it reads the end of the file, the shell terminates.
