continue [n]
       Resume the next iteration of the enclosing for, while, until, or
       select loop.  If n is specified, resume at the nth  enclosing loop.
       n must be >= 1.  If n is greater than the number of enclosing loops,
       the last enclosing loop (the ‘‘top-level’’ loop) is resumed. The
       return value is 0 unless the shell is not executing a loop when
       continue is executed.
