Break

Exit a program loop immediately.

In a For, ForEach, While, Do loop or in a Switch statement you can add a break statement to exit the code block.

Choose the conditions under which you call the continue statement carefully, as it is easy to create an infinite loop. Most commonly an if statement can be used to define the break conditions.

Examples

Count to 10 but stop as soon as you reach number 5:

 PS> $i =0
     while ($i -lt 10)
         {
           $i +=1 
           if ($i -eq 5) {break}
           Write-Host $i
         }
