CONTINUE(P)						     POSIX Programmer's Manual						       CONTINUE(P)

NAME
continue - continue for, while, or until loop SYNOPSIS
continue [n] DESCRIPTION
The continue utility shall return to the top of the smallest enclosing for, while, or until loop, or to the top of the nth enclosing loop, if n is specified. This 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 decimal integer greater than or equal to 1. The default shall be equivalent to n=1. If n is greater than the number of enclosing loops, the outermost enclosing loop shall be used.

PROLOG
This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the correspond- ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux. NAME
break -- exit from for, while, or until loop SYNOPSIS
break [n] DESCRIPTION
The break utility shall exit from the smallest enclosing for, while, or until loop, if any; or from the nth enclosing loop if n is speci- fied. The value of n is an unsigned decimal integer greater than or equal to 1. The default shall be equivalent to n=1. If n is greater than the number of enclosing loops, the outermost enclosing loop shall be exited. Execution shall continue with the command immediately following the loop. OPTIONS

Default. The following sections are informative. APPLICATION USAGE

for i in * do if test -d "$i" then break fi done RATIONALE
In early proposals, consideration was given to expanding the syntax of break and continue to refer to a label associated with the appropri- ate loop as a preferable alternative to the n method. However, this volume of POSIX.1-2008 does reserve the name space of command names ending with a <colon>. It is anticipated that a future implementation could take advantage of this and provide something like: outofloop: for i in a b c d e do for j in 0 1 2 3 4 5 6 7 8 9 do if test -r "${i}${j}" then break outofloop fi done done and that this might be standardized after implementation experience is achieved.
