Syntax
while (condition) {command_block}
Key
condition If this evaluates to TRUE the loop {command_block} runs.
when the loop has run once the condition is evaluated again
command_block Commands, separated by commas, to run each time the loop repeats.
As long as the condition remains true, PowerShell reruns the {command_block} section.
Count to 10:
PS C:\> while($val -ne 10) { $val++ ; Write-Host $val }
You can use carriage returns instead of semi-colons:
while($val -ne 10) {
$val++
Write-Host $val
}
