What is difference between Interactive Mode and Batch Mode of mysql client?

The mysql client program enables the user to send queries to the MySQL server and receive their results. It can be used interactively or it can read query input from a file in batch mode.

Batch mode is useful for running queries that have been prewritten and stored in a file. It's especially valuable for issuing a complex series of queries that's difficult to enter manually, or queries that need to be run automatically by a job scheduler without user intervention.
