Uit "man bash"

:
break [n]
Exit from within a for, while, until, or select loop. If n is
specified, break n levels. n must be >= 1. If n is greater
than the number of enclosing loops, all enclosing loops are
exited. The return value is 0 unless the shell is not executing
a loop when break is executed.
