break and continue

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> $i = 1 # Initial state for iPS> while ($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: 1k: 1k: 2i: 2k: 1k: 2i: 3k: 1k: 2k: 3k: 4

The continue keyword may be used to move on to the next iteration of a loop immediately. ...
