last [expression]

The last command is like the break statement in C (as used in loops); it immediately exits an enclosing loop. The optional expression argument may evaluate to a positive integer number that indicates which level of the nested loops to quit. If this argument is omitted, it defaults to 1, i.e. the innermost loop.

Using this command outside a subroutine causes an immediate run-time error.
