Usage

Prolog

This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

Overview

If n is specified, the continue utility shall return to the top of the nth enclosing for, while, or until loop. If n is not specified, continue shall behave as if n was specified as 1. Returning to the top of the loop involves repeating the condition list of a while or until loop or performing the next assignment of a for loop, and re-executing the loop if appropriate.

The value of n is a positive decimal integer. If n is greater than the number of enclosing loops, the outermost enclosing loop shall be used. If there is no enclosing loop, the behavior is unspecified.

The meaning of ``enclosing'' shall be as specified in the description of the break utility.
