Miscellaneous Statements

You should be aware of two other statements: the break statement and the exit statement.

The break Statement

The break statement can be used to terminate an iteration loop, such as a for, until, or repeat command.

The exit Statement

exit statements can be used to exit a shell program. You can optionally use a number after exit. If the current shell program has been called by another shell program, the calling program can check for the code and make a decision accordingly.
