NAME

break, continue - shell built-in functions to escape from or advance within a controlling while, for, foreach, or until loop  

SYNOPSIS

 

sh

break [n]

continue [n]  

csh

break

continue  

ksh

*break [n]

*continue [n]  

DESCRIPTION

 

sh

The break utility exits from the enclosing for or while loop, if any. If n is specified, break n levels.

The continue utility resumes the next iteration of the enclosing for or while loop. If n is specified, resume at the n-th enclosing loop.  

csh

The break utility resumes execution after the end of the nearest enclosing foreach or while loop. The remaining commands on the current line are executed. This allows multilevel breaks to be written as a list of break commands, all on one line.

The continue utility continues execution of the next iteration of the nearest enclosing while or foreach loop.  

ksh

The break utility exits from the enclosed for, while, until, or select loop, if any. If n is specified, then break n levels. If n is greater than the number of enclosing loops, the outermost enclosing loop shall be exited.

The continue utility resumes the next iteration of the enclosed for, while, until, or select loop. If n is specified then resume at the n-th enclosed loop. If n is greater than the number of enclosing loops, the outermost enclosing loop shall be used.

On this man page, ksh(1) commands that are preceded by one or two * (asterisks) are treated specially in the following ways:

1. Variable assignment lists preceding the command remain in effect when the command completes.


2. I/O redirections are processed after variable assignments.


3. Errors cause a script that contains them to abort.


4. Words that follow a command preceded by ** that are in the format of a variable assignment are expanded with the same rules as a variable assignment. This means that tilde substitution is performed after the = sign, and also that word splitting and file name generation are not performed.
