break can be used to end a loop early. The loop in the following example would continue to 20; break is used to stop the loop at 10:

for ($i = 0; $i -lt 20; $i += 2) {
    Write-Host $i 
    if ($i -eq 10) {
        break    # Stop this loop 
    }
}

break acts on the loop it is nested inside. In the following example, the inner loop breaks early when the i variable is less than or equal to 2:

PS> $i = 1 # Initial state for i
PS> while ($i -le 3) {
>>     Write-Host "i: $i"
>>     $k = 1 # Reset k
>>     while ($k -lt 5) {
>>         Write-Host " k: $k"
>>         $k++ # Increment k
>>         if ($i -le 2 -and $k -ge 3) {
>>             break
>>         }
>>     }
>>     $i++ # Increment i
>> }

i: 1
k: 1
k: 2
i: 2
k: 1
k: 2
i: 3
k: 1
k: 2
k: 3
k: 4

The continue keyword may be used to move on to the next iteration of a loop immediately. For example, the following loop executes a subset of the loop body when the value of the i variable is less than 2:

for ($i = 0; $i -le 5; $i++) { 
    Write-Host $i 
    if ($i -lt 2) { 
        continue    # Continue to the next iteration 
    } 
    Write-Host "Remainder when $i is divided by 2 is $($i % 2)" 
}
